Cetacea: An order of wholly aquatic MAMMALS occurring in all the OCEANS and adjoining seas of the world, as well as in certain river systems. They feed generally on FISHES, cephalopods, and crustaceans. Most are gregarious and most have a relatively long period of parental care and maturation. Included are DOLPHINS; PORPOISES; and WHALES. (From Walker's Mammals of the World, 5th ed, pp969-70)ArtiodactylaDolphins: Mammals of the families Delphinidae (ocean dolphins), Iniidae, Lipotidae, Pontoporiidae, and Platanistidae (all river dolphins). Among the most well-known species are the BOTTLE-NOSED DOLPHIN and the KILLER WHALE (a dolphin). The common name dolphin is applied to small cetaceans having a beaklike snout and a slender, streamlined body, whereas PORPOISES are small cetaceans with a blunt snout and rather stocky body. (From Walker's Mammals of the World, 5th ed, pp978-9)Whales: Large marine mammals of the order CETACEA. In the past, they were commercially valued for whale oil, for their flesh as human food and in ANIMAL FEED and FERTILIZERS, and for baleen. Today, there is a moratorium on most commercial whaling, as all species are either listed as endangered or threatened.Porpoises: Mammals of the family Phocoenidae comprising four genera found in the North Pacific Ocean and both sides of the North Atlantic Ocean and in various other seas. They differ from DOLPHINS in that porpoises have a blunt snout and a rather stocky body while dolphins have a beak-like snout and a slender, streamlined body. They usually travel in small groups. (From Walker's Mammals of the World, 5th ed, pp1003-4)Minke Whale: The species Balaenoptera acutorostrata, in the family Balaenopteridae.

Fitzgerald factor (high molecular weight kininogen) clotting activity in human plasma in health and disease in various animal plasmas. (1/159)

Fitzgerald factor (high molecular weight kininogen) is an agent in normal human plasma that corrects the impaired in vitro surface-mediated plasma reactions of blood coagulation, fibrinolysis, and kinin generation observed in Fitzgerald trait plasma. To assess the possible pathophysiologic role of Fitzgerald factor, its titer was measured by a functional clot-promoting assay. Mean +/- SD in 42 normal adults was 0.99+/-0.25 units/ml, one unit being the activity in 1 ml of normal pooled plasma. No difference in titer was noted between normal men and women, during pregnancy, or after physical exercise. Fitzgerald factor activity was significantly reduced in the plasmas of eight patients with advanced hepatic cirrhosis (0.40+/-0.09 units/ml) and of ten patients with disseminated intravascular coagulation (0.60+/-0.30 units/ml), but was normal in plasmas of patients with other congenital clotting factor deficiencies, nephrotic syndrome, rheumatoid arthritis, systemic lupus erythematosus, or sarcoidosis, or under treatment with warfarin. The plasmas of 21 mammalian species tested appeared to contain Fitzgerald factor activity, but those of two avian, two repitilian, and one amphibian species did not correct the coagulant defect in Fitzgerald trait plasmas.  (+info)

Purification and properties of whale thyroid-stimulating hormone III. Properties of isolated multiple components. (2/159)

Properties of the four purified components of whale thyroid-stimulating hormone (TSH) have been compared. The amino acid composition shows close similarity among these components. Their hexosamine and sialic acid contents are of the same magnitude, whereas the neutral sugar composition differs somewhat from each other. The molecular weight of whale TSH determined by sedimentation equilibrium is 29,000, and no difference in molecular weight as well as in Stokes radius as determined by gel filtration has been detected among these four components. The amino acid and carbohydrate compositions of whale TSH resemble those of TSH from other species, especially those of non-primate mammalian TSH. Whale TSH contains, unlike bovine TSH but like human TSH, 1-2 residues of sialic acid as a constituent carbohydrate.  (+info)

Genealogy of families of SINEs in cetaceans and artiodactyls: the presence of a huge superfamily of tRNA(Glu)-derived families of SINEs. (3/159)

Several novel (sub)families of SINEs were isolated from the genomes of cetaceans and artiodactyls, and their sequences were determined. From comparisons of diagnostic nucleotides among the short interspersed repetitive elements (SINEs) in these (sub)families, we were able to draw the following conclusions. (1) After the divergence of the suborder Tylopoda (camels), the CHRS family of SINEs was newly created from tRNA(Glu) in a common ancestor of the lineages of the Suina (pigs and peccaries), Ruminantia (cows and deer), and Cetacea (whales and dolphins). (2) After divergence of the Suina lineage, the CHR-1 SINE and the CHR-2 SINE were generated successively in a common ancestor of ruminants, hippopotamuses, and cetaceans. (3) In the Ruminantia lineage, the Bov-tA SINE was generated by recombination between the CHR-2 SINE and Bov-A. (4) In the Suina lineage, the CHRS-S SINE was generated from the CHRS SINE. (5) In this latter lineage, the PRE-1 family of SINEs was created by insertion of part of the gene for tRNA(Arg) into the 5' region of the CHRS-S family. The distribution of a particular family of SINEs among species of artiodactyls and cetaceans confirmed the most recent conclusion for paraphyly of the order Artiodactyla. The present study also revealed that a newly created tRNA(Glu)-derived family of SINEs was subjected both to recombination with different units and to duplication of an internal sequence within a SINE unit to generate, during evolution, a huge superfamily of tRNA(Glu)-related families of SINEs that are now found in the genomes of artiodactyls and cetaceans.  (+info)

A review of virus infections of cataceans and the potential impact of morbilliviruses, poxviruses and papillomaviruses on host population dynamics. (4/159)

Viruses belonging to 9 families have been detected in cetaceans. We critically review the clinical features, pathology and epidemiology of the diseases they cause. Cetacean morbillivirus (family Paramyxoviridae) induces a serious disease with a high mortality rate and persists in several populations. It may have long-term effects on the dynamics of cetacean populations either as enzootic infection or recurrent epizootics. The latter presumably have the more profound impact due to removal of sexually mature individuals. Members of the family Poxviridae infect several species of odontocetes, resulting in ring and tattoo skin lesions. Although poxviruses apparently do not induce a high mortality, circumstancial evidence suggests they may be lethal in young animals lacking protective immunity, and thus may negatively affect net recruitment. Papillomaviruses (family Papovaviridae) cause genital warts in at least 3 species of cetaceans. In 10% of male Burmeister's porpoises Phocoena spinipinnis from Peru, lesions were sufficiently severe to at least hamper, if not impede, copulation. Members of the families Herpesviridae, Orthomyxoviridae and Rhabdoviridae were demonstrated in cetaceans suffering serious illnesses, but with the exception of a 'porpoise herpesvirus' their causative role is still tentative. Herpes-like viruses and caliciviruses (Caliciviridae) give rise to cutaneous diseases in Monodontidae and Delphinidae. Antibodies to several serotypes of caliciviruses were found in odontocetes and mysticetes. An unrecognized Hepadnaviridae was detected by serology in a captive Pacific white-sided dolphin Lagenorhynchus obliquidens with chronic persistent hepatitis. Adenoviruses (Adenoviridae) were isolated from the intestinal tracts of mysticeti and a beluga Delphinapterus leucas but were not associated with any pathologies. We discuss the potential impact of Paramyxoviridae, Poxviridae and Papovaviridae on the dynamics of several odontocete populations.  (+info)

Using protein structural information in evolutionary inference: transmembrane proteins. (5/159)

We present a model of amino acid sequence evolution based on a hidden Markov model that extends to transmembrane proteins previous methods that incorporate protein structural information into phylogenetics. Our model aims to give a better understanding of processes of molecular evolution and to extract structural information from multiple alignments of transmembrane sequences and use such information to improve phylogenetic analyses. This should be of value in phylogenetic studies of transmembrane proteins: for example, mitochondrial proteins have acquired a special importance in phylogenetics and are mostly transmembrane proteins. The improvement in fit to example data sets of our new model relative to less complex models of amino acid sequence evolution is statistically tested. To further illustrate the potential utility of our method, phylogeny estimation is performed on primate CCR5 receptor sequences, sequences of l and m subunits of the light reaction center in purple bacteria, guinea pig sequences with respect to lagomorph and rodent sequences of calcitonin receptor and K-substance receptor, and cetacean sequences of cytochrome b.  (+info)

Model dependence of the phylogenetic inference: relationship among carnivores, Perissodactyls and cetartiodactyls as inferred from mitochondrial genome sequences. (6/159)

Some previous analysis of mitochondrial proteins strongly support the Carnivora/Perissodactyla grouping excluding Cetartiodactyla (Artiodactyla + Cetacea) as an outgroup, but the support of the hypothesis remains equivocal from the analysis of several nuclear-encoded proteins. In order to evaluate the strength of the support by mitochondrial proteins, phylogenetic relationship among Carnivora, Perissodactyla, and Cetartiodactyla was estimated with the ML method by using the updated data set of the 12 mitochondrial proteins with several alternative models. The analyses demonstrate that the phylogenetic inference depends on the model used in the ML analysis; i.e., whether the site-heterogeneity is taken into account and whether the rate parameters are estimated for each individual proteins or for the concatenated sequences. Although the analysis of concatenated sequences strongly supports the Carnivora/Perissodactyla grouping, the total evaluation of the separate analyses of individual proteins, which approximates the data better than the concatenated analysis, gives only ambiguous results, and therefore it is concluded that more data are needed to resolve this trichotomy.  (+info)

Elemental analysis of cetacean skull lesions associated with nematode infections. (7/159)

The elemental composition of both healthy and eroded cetacean skulls associated with nematode infections was evaluated. A total of 27 samples of eroded and non-eroded prepared museum cetacean skulls were characterised by elemental (CHN), X-ray fluorescence, and X-ray diffraction methods. The inorganic composition and crystal line structure (hydroxylapatite-like minerals) were similar for both types of skull samples, but the CHN values clearly differed. The results suggest that the carbon-rich fraction is lost in eroded areas, probably as a result of glycosaminoglycan-degrading Crassicauda enzymes.  (+info)

Consistency of SINE insertion topology and flanking sequence tree: quantifying relationships among cetartiodactyls. (8/159)

Short interspersed nuclear elements (SINEs) have been used to generate unambiguous phylogenetic topologies relating eukaryotic taxa. The irreversible nature of SINE retroposition is supported by a large body of comparative genome data and is a fundamental assumption inherent in the value of this qualitative method of inference. Here, we assess the key assumption of unidirectional SINE insertion by comparing the SINE insertion-derived topology and the phylogenetic tree based on seven independent loci of five taxa in the order Cetartiodactyla (Cetacea + Artiodactyla). The data sets and analyses were largely independent, but the loci were, by definition, linked, and thus their consistency supported an irreversible pattern of SINE retroposition. Moreover, our analyses of the flanking sequences provided estimates of divergence times among cetartiodactyl lineages unavailable from SINE insertion analysis alone. Unexpected rate heterogeneity among sites of SINE-flanking sequences and other noncoding DNA sequences were observed. Sequence simulations suggest that this rate heterogeneity may be an artifact resulting from the inaccuracies of the substitution model used.  (+info)

The distribution of cetaceans has always been a difficult and polemic issue, and more so in open waters and pelagic habitats. Due to the high economic cost of surveying and the low detectability of certain cetacean species, the distribution of many cetacean species remains poorly known in many areas. In this work we explore the potential of Spatial Distribution Modelling using presence-only models to obtain a potential distribution map of cetacean populations from opportunistic data. We used opportunistic data from the MONICET database, provided by commercial whale-watching operations in the Azores using a standard, validated, methodology. Two different presence-only models were applied, the Genetic Algorithm for Rule-Set Production (GARP) and the Maximum Entropy Modelling (MaxEnt). Using different GIS programs we prepared a set of different bathimetric derived ecogeographical variables: Depth, Slope, Rugosity and Bathimetric Position Index, using the Bathimetric Terrain Modeller Extension for ...

Archaeoceti ("ancient whales"), or Zeuglodontes in older literature, is a paraphyletic group of primitive cetaceans that lived from the Early Eocene to the late Oligocene (55 to 23 million years ago). Representing the earliest cetacean radiation, they include the initial amphibious stages in cetacean evolution and are thus the ancestors of both modern cetacean suborders, Mysticeti and Odontoceti. This initial diversification occurred in the shallow waters that separated India and Asia 53 to 45 mya, resulting in some 30 species adapted to a fully oceanic life; though both echolocation and filter-feeding evolved during a second radiation 36 to 35 mya. All archaeocetes from the Ypresian (56-47.8 mya) and most from the Lutetian (47.8-41.3 mya) are known exclusively from Indo-Pakistan, but Bartonian (41.3-38.0 mya) and Priabonian (38.0-33.9 mya) genera are known from across Earth, including North America, Egypt, New Zealand, and Europe. Although there is no consensus regarding the mode of locomotion ...

The cetaceans are divided up into 3 major groups of which only 2 have living representatives. These are the baleen or moustache whales, whom lack teeth and depend mostly on small planktonic animals for food, and the Odontocetes, or teethed whales. Most Odontocetes are commonly refered to as dolphins or porpoises.. ...
The CetMap working group recognized the necessity of creating BIAs to incorporate additional information into the mapping tool by identifying areas where cetacean species or populations are known to concentrate for specific behaviors, or are range-limited, but for which there is not sufficient data for their importance to be reflected in the quantitative mapping effort. The result of the BIA assessment process includes narratives, maps, and tables that provide additional context within which to examine potential interactions between cetaceans and human activities. Our aim for this assessment is to combine expert judgement with available data (published or unpublished) to delineate BIAs for each species and each region. Our goal is not to define marine protected areas. Rather, we are identifying sites where cetaceans engage in activities at certain times that contribute to an individuals health and fitness and, ultimately, to the fecundity and survivor-ship of the population. During the ...

The project to restore the living ecosystem of the Mediterranean, MedRec S.A., was headed by a young superbright Nikolaus Vassiliou, with the assistance of the superturing AI NiarchosII and a team of augmented marine biologists. The devastated waters were soon filled with remote drone submarines and underwater survey teams, including biochipped dolphins (there were as yet no geneered neodolphins) and seals. The difficulties of working in the murky depths led the team to explore new possibilities. Vassiliou was a keen follower of genetic research into the evolution of marine mammals, and was informed by contacts within the bioengineering megacorp IntronTEK (soon after renamed GeneTEK) that mapping and extrapolation of various gene complexes had produced a number of possibly viable genotypes for marine humans. These extrapolations were based on cetacean and pinniped analogues, and sounded ideal for the sort of underwater ecological management his group was engaged in. The plans to gestate the new ...

River dolphins are a very widespread group of fully aquatic mammals that reside exclusively in freshwater or brackish water. They are an informal grouping of dolphins, which is a paraphyletic group within the infraorder Cetacea. The river dolphins comprise the extant families Platanistidae (the Indian dolphins), Iniidae (the Amazonian dolphins), and Pontoporiidae (the brackish dolphins). There are five extant species of river dolphins, and two subspecies. River dolphins, alongside other cetaceans, belong to the clade Cetartiodactyla, with even-toed ungulates, and their closest living relatives the hippopotamuses, having diverged about 40 million years ago. River dolphins are relatively small compared to other dolphins, having evolved to survive in warm, shallow water and strong river currents. They range in size from the 5-foot (1.5 m) long South Asian river dolphin to the 8-foot (2.4 m) and 220-pound (100 kg) Amazon river dolphin. Several species exhibit sexual dimorphism, in that the males are ...

The order Cetacea (pronounced /sɨˈteɪʃ(i)ə/, L. cetus, whale, from Greek) includes the marine mammals commonly known as whales, dolphins, and porpoises. Cetus is Latin and is used in biological names to mean "whale"; its original meaning, "large sea animal", was more general. It comes from Ancient Greek κῆτος (kētos), meaning "whale" or "any huge fish or sea monster". In Greek mythology the monster Perseus defeated was called Ceto, which is depicted by the constellation of Cetus. Cetology is the branch of marine science associated with the study of cetaceans ...

Identifying the genetic basis of adaptive phenotypes can be a significant step towards understanding how that phenotype evolved. With the increased availability of interspecific molecular data, an approach to uncover such genes has been to search for signatures of adaptive evolution at the molecular level. Many analyses have adopted a candidate gene approach, focusing on genes with important developmental roles. One such candidate gene is ASPM, which is involved in neurogenesis and associated with major neurological disorders [1]. The molecular evolution of ASPM has been investigated for a decade (see electronic supplementary material, table S1), under the hypothesis that it contributes to primate brain evolution. A recent study by Xu et al. [2] extends the taxonomic scope by demonstrating that ASPM evolved adaptively in cetaceans. However, descriptive studies of patterns of selection are now being supplanted by those that explicitly test for gene-phenotype associations. Using such an approach, ...
The cheek teeth [of Aetiocetus] are leaf shaped, similar to those of Patriocetus, but smaller and with the roots coalesced. The triangular rostrum, reduced dentition, and the conformation of the posterior ends of the maxillae, premaxillae, and nasals (Ernlong, 1966:s) are characters that would be expected in the ancestor of the mysticetes. Thenius (1969:489) stated: "Even if Aetiocetus, because of its geologic age (upper Oligocene) cannot be a direct stem form of the cetotheres, yet this genus documents that a specific family (Aetiocetidae) must be classified as ancestor, the link between ancient and baleen whales.. "Among the few Cetacea known from deposits of middle Oligocene age are two occurrences of unmistakable Mysticeti. One of these, Mauicetus Benham, 1939, from New Zealafid, has long nasals embraced by premaxillae and maxillae which extend posteriorly to the level of the supraorbital process of the frontal, together with an anteriorly thrusting triangular supraoccipital. The Oligocene ...

Solution #1: When the desmostylian, Desmostylus hesperus (Marsh 1888), and the odontocete, Zygorhiza kochii (True 1908), are added to the LRT (Fig. 2) the Odontoceti and the Mysticeti finally nest apart when tested together. Both of these transitional taxa are known from complete skeletons that link them to both ancestors and descendants. The addition of these two taxa makes the transition more seamless.. Solution #2: The RBCM specimen referred to Behemotops includes a partial skull, 12 thoracic vertebrae, 17 rib fragments, a very partial scapula and most of a humerus. Authors Beatty and Cockburn 2015 also report, "No other skeletal elements of desmostylians are found anywhere nearby, and the only other bone found in the area was a caudal vertebrae from a Tursiops-sized odontocete."

3 where dr is the centre-to-centre spacing between the receptors of the retina. This introduces a trade-off, since increasing the focal length of the eye on its own increases the f-number and so decreases sensitivity. One way to achieve both good sensitivity and acuity is to allow the focal length to increase, but simultaneously to increase the aperture size to avoid increasing the f-number. Hence, it may be that the large eyes of ichthyosaurs were a result of simultaneous selection for both high sensitivity and acuity. However, it is interesting to note that the visual acuities of extant cetaceans and pinnipeds are generally good and comparable with those of terrestrial hunters such as the domestic cat Felis catus (Muir and Mitchell, 1973).. Visual performance also depends on retinal pooling - the summation of signals from individual sensory cells to produce a retina with fewer individual receptor units but greater sensitivity per receptor. With the longer focal length of its larger eye, an ...
Holy, Trippel and Kings gillnets consist of a single wall of netting that is injected with barium sulphate, which makes the netting stiffer less likely to tightly tangle around a fin, flipper or tail. Barium sulphate also makes the nets more acoustically detectable for whales, dolphins and porpoises that are using echolocation to find objects. The ropes they use for float lines are specially designed to be easily broken (under a force of 1,100 lbs) so large cetaceans can wrestle their way free. In order to keep cetaceans away from the floatlines in the first place, the team designed a glowing rope that may visually deter the animals ...

The study is based on data gathered by the Kandalaksha State Sanctuary during 1947-1961. Most of the mammals were observed from islands during the navigational (free ice) period. It appears that the number of belugas that visit the gulf has greatly decreased. The greatest numbers of the mammals were observed in August-September -- a time when large concentrations of herring approach the coast. Usually, the number of belugas varies from year to year; the minimum was reached in 1948-1951 (5 in a year); the maxima in 1953 (37) and 1947 (32). (Author)(*CETACEA

Breeding occurs between males and females from unrelated pods. Gestation lasts 15 months, and calves are usually born in the winter during the time squid are spawning. Newborn short-finned pilot whales weigh 140 g on average. Females are the sole caretakers of the calves, and both young and old females make a contribution. The weaning period lasts 24 months, and the young are independent after 3 years. Adult females typically give birth every 7 years, and have 4 to 5 calves in their lifetime. Young females are sexually mature in 7 to 12 years, and in 9 years on average. Males are sexually mature in 7 to 17 years, and in 14.6 years on average. Males rarely stay within the same pod after reaching sexual maturity. Males have been known to move from pod to pod throughout their lifetime. Females breed until reaching the age of 40, at which they experience menopause. Males can breed until the time of their death, which is normally between 40 and 50 years of age.

What is not known about Waco is that the final assault plan was amended on the ground by the tactical field commanders on the very day of the assault. That alteration had been discussed and rejected by the FBI brass over several weeks. Nonetheless, the FBI HRT commander, Richard Rogers implemented the rejected plan via a loophole signed by Janet Reno the morning of the final assault on April 19. That alteration was identical to the gassing and demolition plan that two Delta Force advisors seconded to the Justice Dept. in a principals meeting of April 14. Those two advisors supported the rejected plan that was later implemented "hypothetically" in order to conform to the letter of Posse Comitatus law. I also have published a peer-reviewed article with this finding. It is based on government documents--all open source. The rejected plan supported by Jeff Jamar, Richard Rogers, and the two Delta Force officers resulted in a disaster that did not have to happen. It was an ill-advised tactical ...

Minke whales feed on fish and various invertebrates; like all baleen whales they filter their food from the water using their baleen plates like sieves. Although largely a solitary species, when feeding minke whales can often be seen in pairs, and on particularly good feeding grounds up to a hundred individuals may congregate. A number of feeding techniques have been observed, including trapping shoals of fish against the surface of the water. After a ten month gestation period, births occur in mid-winter, at birth the calf measures up to 2.8 metres in length. It will be weaned at four months of age, and will stay with its mother for up to two years, becoming sexually mature at seven years of age. Minke whales have an average life span of around 50 years. Minke whales are rather inquisitive and often swim by the side of boats for up to half an hour ...

The dorsal fin is hooked and set far back on the body. The tail is slightly notched at the mid-line, and scalloped along the posterior edge. The cervical vertebrae are not fused. The baleen plates are broad and short, the left and right rows being joined anteriorly. The animals are typically grey on the dorsal surface, with some white on the ventral surface; but Megaptera novaengliae (humpback) may be black above and below, with white flippers. Members of the family feed on krill and small fish, and occur in both hemispheres. They grow to 7-30 m depending on species. There are six species, in two genera: Balaenoptera (B. acutorostrata, minke or lesser rorqual; B. borealis, sei; B. physalus, fin; B. musculus, blue; B. edeni, Brydes); and Megaptera novaengliae (humpback). ...

Reproductive hormone levels, particularly progesterone, have been measured in cetacean blubber samples and blow samples as indicators of pregnancy in various cetacean species. Other studies have shown, that high progesterone levels are indicative of pregnancy. Therefore, we can collect information on pregnancy rates in our humpback whale population, as well as, calf survival rates, when females are seen the following season with or without a calf.. In the same matrices, the blubber and the blow, the stress hormone cortisol will also be measured. In their natural environment, animals experience a variety of environmental and anthropogenically influenced conditions, which can induce a physiological stress response. Stress responses ...
In 1999, a researcher suffered headaches, lassitude and a severe sinusitis after exposure to marine mammal strains of Brucella with which the worker was in contact. The symptoms resolved in one week after treatment with doxycycline and rifampin. The researcher had a positive titer for Brucella, and the organism was cultured from blood samples. PCR-RFLP was used to positively identify the isolates as being comparable to marine mammal Brucella (Brew and Staunton 1999). Organisms Brucella ssp. are gram-negative intracellular bacteria and are a major source of zoonoses worldwide. B. melitensus, B. abortus, and B. suis are some species commonly recognized to play a role in human and animal health. Nomenclature for marine mammal strains of Brucella has not yet been fully developed, but B. maris and B. pinnipedia have so far been named. Transmission occurs primarily through contact with aborted fetal material, and consumption of contaminated milk. ...
The Influence of Man: The Indus River Dolphins have suffered as a result of incidental and direct exploitation. They have been accidentally caught in fishing nets, but have also been hunted for meat, oil and traditional medicines. They are now fully protected in all of their range.. Flippers: The dolphin has very broad flippers to help it stabilise at slow swimming speed.. Reproduction: The gestation period for the dolphins is approximately 10 months and it is believed that the babies are born in spring. When a baby is born it is about 70 cm long (almost the length of a domestic cat and the mother helps it to the surface to breathe. Babies stay close to their mother for the first six months of their life.. Life span: Scientists think that these dolphins can live for approximately 20 years.. Introduction:The Indus River Dolphin is high on the list of the worlds endangered species. There are estimated to be fewer than 1000 of these dolphins remaining in the whole of Pakistan, most of them between ...

Small coastal dolphins endemic to south-eastern Australia have variously been assigned to described species Tursiops truncatus, T. aduncus or T. maugeanus; however the specific affinities of these animals is controversial and have recently been questioned. Historically the southern Australian Tursiops was identified as unique and was formally named Tursiops maugeanus but was later synonymised with T. truncatus. Morphologically, these coastal dolphins share some characters with both aforementioned recognised Tursiops species, but they also possess unique characters not found in either. Recent mtDNA and microsatellite genetic evidence indicates deep evolutionary divergence between this dolphin and the two currently recognised Tursiops species. However, in accordance with the recommendations of the Workshop on Cetacean Systematics, and the Unified Species Concept the use of molecular evidence alone is inadequate for describing new species. Here we describe the macro-morphological, colouration and cranial

The common dolphins underwent centuries of evolution to move from terrestrial to aquatic mammals. These mammals share much of their evolution with the other members of the Cetacea. Various genes went through positive selection, or Darwinian selection, to be in the form they take today. Numerous studies show the about 2.26%-4.8%, around 376 genes, of genes were selected for with positive selection. This gene selection is believed to help the overall system development, pattern of specification process, and mesoderm development.[6] Morphological evolution is evident as the Delphinus form is significantly different than the body of the Pakicetus. In dolphins, there is a overrepresentation in genes of MET, FOXP2, TRIM63, FOXO3, CD2, and PTCH1 which are possibly responsible for the morphological evolution. Evidence shows that there could be changes in transcription factors, expression patterns, and in protein function that is also responsible for the morphological changes.[7] Adapting to the aquatics ...
The phenomenon of a remarkable conservation of the X chromosome in eutherian mammals has been first described by Susumu Ohno in 1964. A notable exception is the cetartiodactyl X chromosome, which varies widely in morphology and G-banding pattern between species. It is hypothesized that this sex chromosome has undergone multiple rearrangements that changed the centromere position and the order of syntenic segments over the last 80 million years of Cetartiodactyla speciation. To investigate its evolution we have selected 26 evolutionarily conserved bacterial artificial chromosome (BAC) clones from the cattle CHORI-240 library evenly distributed along the cattle X chromosome. High-resolution BAC maps of the X chromosome on a representative range of cetartiodactyl species from different branches: pig (Suidae), alpaca (Camelidae), gray whale (Cetacea), hippopotamus (Hippopotamidae), Java mouse-deer (Tragulidae), pronghorn (Antilocapridae), Siberian musk deer (Moschidae), and giraffe (Giraffidae) were ...
Dolphins are highly intelligent social animals. Many species appear to live in cooperative groups, groups that work together. They may live in groups called pods of fewer than five or as many as several thousand. To some extent, group size depends on the availability of food. Within a large group, animals often separate by age and sex.. Dolphins have excellent hearing and communicate with each other by producing a variety of different sounds, often identified as "clicks," "pulses," and "whistles." Some of these sounds may be identifiers for individual animals, but this communication is not well understood. Dolphins living in clear water may also communicate by flipping and flashing patches of color on their bodies.. There are many examples of dolphins working cooperatively. They may work together to locate and round up a school of fish or chase them into shallow water or to attack a predator, an animal that hunts them for food. They have been seen helping newborn or injured animals to the ...
Im a paleontologist and adjunct faculty at College of Charleston in South Carolina, with research interests in Cenozoic marine vertebrates with an emphasis on marine mammals (whales, dolphins, pinnipeds, otters, sea cows, and others), but I willingly entertain brief distractions into the worlds of marine birds, sharks, and fish. My M.S. (2011, MSU-Bozeman) focused on marine vertebrate taphonomy whilst my Ph.D. (2015, U. Otago, NZ) focused on Oligocene baleen whales from New Zealand. Current research is concerned with fossil cetaceans from South Carolina including Oligocene eomysticetids, toothed mysticetes, and archaic dolphins ...
Further evidence that food enzymes have been ordained by nature over countless millions of years to help digest the food of all creatures, including human beings, is supplied by special organs with no function except to serve as food-enzymes stomachs. Food enzymes are made up of proteolytic food enzymes to digest protein, amyloytic food enzymes to digest carbohydrates, and lipolytic food enzymes to digest fats. The so-called killer whale, a member of Cetacea, has a food enzyme stomach larger than any land creature. The food-enzyme stomach of this whale has been found to contain more than a dozen porpoises and seals. In one instance this enormous food enzyme stomach, which is the first of the whales three stomachs, and much larger than the others, was found to house the bodies of 32 entire seals undergoing digestion by the seal enzymes, which now belong to the whale, and are the whales food enzymes. The remarkable fact elicited by physiologists is that the first stomach (forestomach) has no ...
Just as in humans, it is possible to learn about a dolphins health from physiological biomarkers measured in their blood. However, blood sampling is a medical procedure that requires careful handling of animals in controlled conditions, which can be challenging and untenable in some field research applications.

The name Perissodactyla means "odd-toed." This group of ungulates includes horses, tapirs, and rhinos. The name of their order derives from the fact that their middle toe is larger than the others, and the plane of symmetry of the foot passes through it, a condition called mesaxonic. Most species have three digits on the hindfoot and three or four on the forefoot, but in some only a single digit, the third, remains. Some species have horns, but these are dermal structures without bony cores, and they are located on the nasals or frontals in the midline of the skull. This contrasts with the horns of artiodactyls, which have bone cores, are paired, and are located on the frontals. The anterior part of the skull of perissodactyls is elongated and accomodates a full series of large cheek teeth (most have a total of 44 teeth). Molars and premolars are hypsodont in grazing forms such as horses, and brachydont in browsers such as tapirs. Modern species are lophodont (complexly so in equids), in ...
Several workers have made a strong case that changes in outcrop preservation and availability exert a substantial bias on coincident changes in Phanerozoic biodiversity (e.g. Raup 1972; Peters & Foote 2001, 2002; Smith 2001; Smith & McGowan 2007). However, most of the studies corroborating the prevalence of such a bias have focused on global marine diversity (Peters & Foote 2001, 2002; Smith 2001; Smith & McGowan 2007) or large faunal groups at high taxonomic levels, such as Mollusca (Crampton et al. 2003). The results of the present study stand in contrast to both their main conclusions and the comprehensiveness of the faunal groups investigated. None of the three groups of marine mammals examined here exceeds the level of a mammalian order. More importantly, the results of this study provide only limited evidence for a strong influence of the amount of available rock on marine mammal palaeodiversity, since all of the correlations of marine mammal diversity with outcrop area observed here are ...
Canada s coastal regions are an excellent source of marine renewable energy. These regions are also popular with marine mammals, providing good feeding opportunities. However little is known about how marine mammals will be affected by tidal energy developments. Concerns include the impacts of sound on animals ability to find food and navigate, the indirect effects of changes in prey distribution and abundance, and the direct impacts of collision with tidal energy structures in the water column. The objectives of this project are to better understand how marine mammals interact with tidal energy devices using a combination of traditional passive acoustic monitoring and novel sonar imaging methods. This study will improve our understanding of environmental effects and will contribute to the development of crucial collision risk models. This project will allow SMRU Canada to help move marine renewables forward into a cleaner future, both in Canada and elsewhere in the world.. ...
Hydrophones allow detection of sounds emitted underwater by the marine mammals (e.g. [3]). The sensitivity of these acoustic receivers and the bandwidth of the hydrophones frequency spectrum in relation to the ambient noise, define the detection range of the hydrophones and hence the variety of marine mammals it can detect. The receiving hydrophones are either being towed behind a vessel ([4]) or deployed as stationary hydrophones (SOSUS [5] [6], T-PODs ([7] [8]). When towed, usually two or more hydrophones are installed in an array. The time difference of arrival of the animals individual sounds at the spatially separated hydrophones allows to triangulate and analyse a bearing of the received sound, thereby locating its sound source. Usually special sound recognition software is needed to identify the species to which the recorded sounds can be attributed to. With decreasing the size of the technical acoustic components, it is possible to deploy sound recording systems on marine mammals in ...
Unfortunately, this skull is in one of the hardest primary sedimentary rocks Ive ever seen or hammered upon, and in a block the size of a refridgerator. Theres no way this thing is coming out without access to a jackhammer and a truck. There are four labeled features that help identify it as Herpetocetus. Some of these are not unique to Herpetocetus, but do not occur in any other known contemporaneous mysticetes, so can be used for purposes of identification. 1) The cranial vertex; the vertex is pyramidal in shape, bears a distinct saggital crest on the supraoccipital, which is also very acute. 2) There is a distinct deep fossa medial of the dorsal crest of the squamosal, which is an synapomorphy of the clade Herpetocetinae. 3) The zygomatic process of the squamosal is anteriorly oriented. 4) The postorbital process is elongate and finger like, which may be a reversal to the primitive condition of mysticetes ...

BACKGROUND: Understanding the role of seascape in shaping genetic and demographic population structure is highly challenging for marine pelagic species such as cetaceans for which there is generally little evidence of what could effectively restrict their dispersal. In the present work, we applied a combination of recent individual-based landscape genetic approaches to investigate the population genetic structure of a highly mobile extensive range cetacean, the harbour porpoise in the eastern North Atlantic, with regards to oceanographic characteristics that could constrain its dispersal. RESULTS: Analyses of 10 microsatellite loci for 752 individuals revealed that most of the sampled range in the eastern North Atlantic behaves as a continuous population ...

Many proteoglycans (PGs) in the tumor microenvironment have been shown to be key macromolecules that contribute to biology of various types of cancer including proliferation, adhesion, angiogenesis and metastasis, affecting tumor progress. The four main types of proteoglycans include hyaluronan (HA), which does not occur as a PG but in free form, heparan sulfate proteoglycans (HSPGs), chondroitin sulfate proteoglycans (CSPGs), dematan sulfate proteoglycans (DSPG) and keratan sulfate proteoglycans (KSPGs) [BR:00535]. Among these proteoglycans such as HA, acting with CD44, promotes tumor cell growth and migration, whereas other proteoglycans such as syndecans (-1~-4), glypican (-1, -3) and perlecan may interact with growth factors, cytokines, morphogens and enzymes through HS chains [BR: 00536], also leading to tumor growth and invasion. In contrast, some of the small leucine-rich proteolgycans, such as decorin and lumican, can function as tumor repressors, and modulate the signaling pathways by ...
A speculative life rendering of the fossil whale [I]Balaenoptera bertae[/I] unearthed in the San Francisco Bay Area. The whale belongs within the same genus as minke and fin whales, indicating that the [I]Balaenoptera[/I] lineage has lasted for 3-4 million years. [I]Balaenoptera bertae[/I] would have been approximately 5-6 meters in length, slightly smaller than modern minke whales. It was named by University of Otago Ph.D. student Robert Boessenecker in honor of San Diego State Universitys Professor Annalisa Berta.
ABSTRACT: Understanding the factors influencing habitat selection is critical to improving management and conservation plans for large whales. Many studies have linked the distribution of cetaceans to basic environmental features such as underwater topography and sea surface temperature (SST), but the mechanisms underlying these relationships are poorly understood. Dynamic mesoscale processes like thermal fronts are prime candidates to link physiographic factors to whale distribution because they increase biological productivity and aggregate prey. However, previous studies of large whales have found little evidence of such associations, possibly because they were not at the appropriate spatio-temporal scales. We quantified the relationship between SST fronts and the distribution of blue Balaenoptera musculus, finback B. physalus, humpback Megaptera novaeangliae and minke B. acutorostrata whales in the northern Gulf of St. Lawrence. We compared the distribution of 1094 whale sightings collected ...
Pilot whales have a tendency to follow conspecific pilot leaders, which may explain their common name and also make them particularly vulnerable to drive fisheries and mass stranding events (Kritzler, 1952; Fehring and Wells, 1976; Ellis, 1982). Long-finned pilot whales (Globicephala melas Traill 1809) inhabit the deep waters of the North Atlantic and feed on squid and other prey normally found down to 600 m (Baird et al., 2002; Aguilar Soto et al., 2008). They do not usually dive as deeply as other pelagic odontocete cetaceans such as beaked whales or sperm whales (Heide-Jorgensen et al., 2002). Long-finned pilot whales are very similar to the short-finned pilot whale (Globicephala macrorhynchus) and differ primarily by the habitats they occupy, the long-finned pilot whale being found primarily in subpolar oceanic regions while the short-finned pilot whale is found in tropical and subtropical regions. Both species are classified as Data Deficient on the IUCN Redlist and have been included in ...
Marine mammals possess adaptations for repetitive and extended diving to great depths without suffering the ill effects seen in humans [e.g. decompression sickness (DCS)] which involve altered immune activity. In recent decades, DCS-like symptoms in marine mammals have increased concerns about marine mammal health and whether anthropogenic activities can interfere with adaptive dive responses, increasing susceptibility to dive related pathologies. The purpose of this work was to address these concerns by: 1) evaluating the in vitro response of marine mammal immune cells to increased pressure, 2) comparing the response of cells between baseline and stressor conditions, and 3) developing a non -invasive means of monitoring cortisol in belugas (Delphinapterus leucas). Blood samples were obtained from belugas during baseline and stressor (e.g. out of water examination, wild chase and capture) conditions, as well as from stranded harbor seals (Phoca vitulina), harp seals (Phoca groenlandica) and grey seals
As with seabirds and fishes, the composition of the sanctuarys marine mammal community is a mix of permanent and seasonal residents as well as species that use these waters for shorter periods - either as a feeding destination or in transit during long-distance migratory journeys.. Californias central coast is located on a migration pathway between northern feeding grounds and temperate and tropical breeding areas for many marine mammal species. For example, gray whales traverse these waters on their annual migrations between Arctic feeding grounds and Mexican breeding areas; however, in some years, many gray whales will also over-summer in the sanctuary to feed.. Blue and humpback whales are seasonally abundant, migrating into the sanctuary during late spring, summer and fall to feed in its productive waters. Northern fur seals and California sea lions are also seasonally abundant, coming here to forage during the fall through the spring. Smaller cetaceans (e.g., several dolphin and porpoise ...

South Pacific humpback whales were devastated by commercial whaling in their Antarctic feeding areas during the 20th century. Understanding migratory connections and current abundance of these isolated breeding stocks is crucial for the allocation of historical Antarctic catches in population dynamic models used to assess current recovery. However, only a small number of migratory connections have been documented between Oceania breeding stocks within the South Pacific and feeding areas in the Antarctic. In addition, little is known about abundance of these stocks which encompass a vast oceanic region. For this thesis I first used mixed-stock analysis (MSA) to allocate migratory connections from four Antarctic feeding areas (n=142) to seven South Pacific breeding stocks (n=1,373), including four in Oceania, based on genetic marker frequencies. The use of this method was justified by the breeding stocks showing genetic differentiation at the haplotype level with an F[subscript ST] value of 0.027 ...

  • Trees based only on data that fossilize continue to show the classic arrangement of relationships within Artiodactyla with Cetacea grouping outside the clade, a signal incongruent with the molecular data that dominate the total evidence result. (plos.org)
  • Graur and Higgins ( 8 ) proposed a Ruminantia/Cetacea clade to the exclusion of Suiformes. (pnas.org)
  • When the temporal range of Archaeoceti is calibrated radiometrically, comparison of likelihoods constrains the time of origin of Archaeoceti and hence Cetacea to about 54-55 Ma (beginning of the Eocene), whereas their divergence from extant Artiodactyla may have been as early as 64-65 Ma (beginning of the Cenozoic). (pnas.org)
  • The study of phylogenetic data that fossilizes (primarily skeletal and dental morphology) has been particularly important because it is by studying extinct species that we can reconstruct the order of character acquisition that led to the origin of Cetacea (see review of studies in , ). (plos.org)
  • In this report, phylogenetic relationships between Cetacea and artiodactyls are tested with a combination of 15 published data sets plus new DNA sequence data from two nuclear loci, interphotoreceptor retinoid-binding protein (IRBP) and von Willebrand factor (vWF). (nih.gov)
  • A chronicle of phylogenetic results over the past 3 years suggests that cladistic relationships between Cetacea and artiodactyls have been stable to increased taxonomic sampling and to the addition of more than 1,400 informative characters from 15 data sets. (nih.gov)
  • We reexamine relationships of critical extinct taxa that impact our understanding of the origin of Cetacea. (plos.org)
  • Molecular genetic study of the beluga (Delphinapterus leucas: Cetacea, Monodontidae) summering in. (deepdyve.com)
  • This not only extends the fossil record of Cetacea back in time, but also reinforces the idea that whales originated on the margin of Tethys and corroborates interpretation of pakicetids as an initial amphibious stage of cetacean evolution entering Tethys to feed on fish. (pnas.org)
  • The fossil record of whales is rich, and recent discoveries have shed much light on the origin of the Cetacea. (berkeley.edu)
  • The relationships of †Mesonychia and † Indohyus are highly unstable, however - in trees only two steps longer than minimum length, †Mesonychia falls inside Artiodactyla and displaces † Indohyus from a position close to Cetacea. (plos.org)
  • Many of these data sets suggest that Artiodactyla (even-toed ungulates) is paraphyletic and that Cetacea (whales) represents a highly derived "artiodactyl" subgroup. (nih.gov)
