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 ...

Neural networks use electronic analogs of the neurons in our brains. But it doesnt seem likely that just making enough electronic neurons would create a human-brain-like thinking machine. Consider that animal brains are sometimes larger than ours - a sperm whales brain weighs 17 pounds - yet we dont think they are as smart as humans or even dogs who have a much smaller brain. MIT researchers have discovered differences between human brain cells and animal ones that might help clear up some of that mystery. You can see a video about the work theyve done below.. Neurons have long finger-like structures known as dendrites. These act like comparators, taking input from other neurons and firing if the inputs exceed a threshold. Like any kind of conductor, the longer the dendrite, the weaker the signal. Naively, this seems bad for humans. To understand why, consider a rat. A rats cortex has six layers, just like ours. However, whereas the rats brain is tiny and 30% cortex, our brains are much ...

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." Now, Im no whale expert, ...
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 U.S. National Marine Fisheries Service has published for comment a draft national Procedural Directive clarifying the process for eligible permit applicants to obtain releasable marine mammals for public display purposes under the Marine Mammal Protection Act. Releasable marine mammals are those that were successfully rehabilitated by the Marine Mammal Health and Stranding Response Programs network of stranding centers and have been determined by the rehabilitation facilitys attending veterinarian to be candidates for return to the wild. NMFS will no longer grant permits for the specific purpose of retaining releasable marine mammals for public display. Instead, applicants will now need to apply for a permit to take (collect) animals from the wild pursuant to the MMPA. Non-releasable animals, on the other hand, may still be obtained through NMFS administrative procedures.. NMFS must receive any comments must by December 15, 2017..

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
MARINE MAMMALS. (plate VIII., p. 216). Section I.-Introductory Remarks Most of the recent writers on geographical distribution have confined their attention to terrestrial Mammals, or at any rate have but casually alluded to the marine groups of that Class. The seven previous chapters having been devoted to the terrestrial Mammals, it is proposed now to examine the principal facts connected with the distribution over the worlds surface of the Marine or aquatic members of the Class.. Aquatic Mammals which pass their lives entirely, or for the greater part, in the water are, of course, subject to very different laws of distribution from the terrestrial forms. As regards aquatic Mammals, land is of course an impassable barrier to their extension, and, subject to restrictions in certain cases, water offers them a free passage. Just the opposite is the case with the terrestrial Mammals, to which in most cases land offers a free passage, while seas and rivers restrain the extension of their ...
