Cuba
An island in the Greater Antilles in the West Indies, south of Florida. With the adjacent islands it forms the Republic of Cuba. Its capital is Havana. It was discovered by Columbus on his first voyage in 1492 and conquered by Spain in 1511. It has a varied history under Spain, Great Britain, and the United States but has been independent since 1902. The name Cuba is said to be an Indian name of unknown origin but the language that gave the name is extinct, so the etymology is a conjecture.

Bhutan
A kingdom in the eastern Himalayas on the northeast border of India, bounded on the north by Tibet, on the east by Assam, on the south by Assam and West Bengal, and on the west by Sikkim and Tibet. From 1720 to 1970 it was under Chinese or Indian domination. In 1971 it became a member of the United Nations. The name comes from the Sanskrit bhota, the name for Tibet, + anta, end, with reference to its location at the southern extremity of Tibet.

ROLE OF THE GAMETE MEMBRANES IN FERTILIZATION IN SACCOGLOSSUS KOWALEVSKII (ENTEROPNEUSTA). I. THE ACROSOMAL REGION AND ITS CHANGES IN EARLY STAGES OF FERTILIZATION. (1/153)
Previous electron microscope studies of sperm-egg association in the annelid Hydroides revealed novel aspects with respect to the acrosomal region. To determine whether these aspects were unique, a comparable study was made of a species belonging to a widely separated phylum, Hemichordata. Osmium tetroxide-fixed polyspermic material of the enteropneust, Saccoglossus, was used. The acrosomal region includes the membrane-bounded acrosome, with its large acrosomal granule and shallow adnuclear invagination, and the periacrosomal material which surrounds the acrosome except at the apex; here, the acrosomal membrane lies very close to the enclosing sperm plasma membrane. After reaching the egg envelope, the spermatozoon is activated and undergoes a series of changes: the apex dehisces and around the resulting orifice the acrosomal and sperm plasma membranes form a continuous mosaic membrane. The acrosomal granule disappears. Within 7 seconds the invagination becomes the acrosomal tubule, spans the egg envelopes, and meets the egg plasma membrane. The rest of the acrosomal vesicle everts. The periacrosomal mass changes profoundly: part becomes a fibrous core (possibly equivalent to a perforatorium); part remains as a peripheral ring. The basic pattern of structure and sperm-egg association in Saccoglossus is the same as in Hydroides. Previous evidence from four other phyla as interpreted here also indicates conformity to this pattern. The major role of the acrosome is apparently to deliver the sperm plasma membrane to the egg plasma membrane. (+info)ROLE OF THE GAMETE MEMBRANES IN FERTILIZATION IN SACCOGLOSSUS KOWALEVSKII (ENTEROPNEUSTA). II. ZYGOTE FORMATION BY GAMETE MEMBRANE FUSION. (2/153)
An earlier paper showed that in Saccoglossus the acrosomal tubule makes contact with the egg plasma membrane. The present paper includes evidence that the sperm and egg plasma membranes fuse to establish the single continuous zygote membrane which, consequently, is a mosaic. Contrary to the general hypothesis of Tyler, pinocytosis or phagocytosis plays no role in zygote formation. Contact between the gametes is actually between two newly exposed surfaces: in the spermatozoon, the surface was formerly the interior of the acrosomal vesicle; in the egg, it was membrane previously covered by the egg envelopes. The concept that all the events of fertilization are mediated by a fertilizin-antifertilizin reaction seems an oversimplification of events actually observed: rather, the evidence indicates that a series of specific biochemical interactions probably would be involved. Gamete membrane fusion permits sperm periacrosomal material to meet the egg cytoplasm; if an activating substance exists in the spermatozoon it probably is periacrosomal rather than acrosomal in origin. The contents of the acrosome are expended in the process of delivering the sperm plasma membrane to the egg plasma membrane. After these membranes coalesce, the sperm nucleus and other internal sperm structures move into the egg cytoplasm. (+info)AN UNUSUAL CONFIGURATION OF THE GOLGI COMPLEX IN PIGMENT-PRODUCING "TEST" CELLS OF THE OVARY OF THE TUNICATE, STYELA. (3/153)
The test cell in the ovary of the tunicate Styela contains a large and robust Golgi complex which demonstrates a regional structural differentiation. In one of the regions, branching of the lamellae occurs resulting in a honeycomb or lattice-type arrangement. Small, dense granules or homogeneous material of moderate density may be present within certain of the Golgi cisternae. The close association, or continuity in some cases, between elements of the Golgi complex and immature forms of pigment suggests that the Golgi complex in these cells is involved in pigment formation. These relationships are shown and discussed in terms of possible functional significance. (+info)A CYTOCHEMICAL STUDY OF CYTOPLASMIC BASIC PROTEINS IN THE ASCIDIAN OOCYTE. (4/153)
The cytoplasm of young oocytes of the ascidians contains high concentrations of proteins which are stainable with alkaline fast green at pH 8.1 and above. These proteins cannot be stained even with acid dyes at low pH unless RNA is removed. Deamination and formalin blockage of amino groups is incapable of destroying the net positive charge on these protein molecules in the presence of RNA, but these treatments destroy the charge if RNA is removed. It is therefore concluded that basic proteins and RNA exist as a nucleoprotein complex in the ribosomes of these young oocytes. The detectable RNA of the mature oocytes and unfertilized eggs shows no evidence of being associated with basic proteins. (+info)Amphioxus and ascidian Dmbx homeobox genes give clues to the vertebrate origins of midbrain development. (5/153)
The ancestral chordate neural tube had a tripartite structure, comprising anterior, midbrain-hindbrain boundary (MHB) and posterior regions. The most anterior region encompasses both forebrain and midbrain in vertebrates. It is not clear when or how the distinction between these two functionally and developmentally distinct regions arose in evolution. Recently, we reported a mouse PRD-class homeobox gene, Dmbx1, expressed in the presumptive midbrain at early developmental stages, and the hindbrain at later stages, with exclusion from the MHB. This gene provides a route to investigate the evolution of midbrain development. We report the cloning, genomic structure, phylogeny and embryonic expression of Dmbx genes from amphioxus and from Ciona, representing the two most closely related lineages to the vertebrates. Our analyses show that Dmbx genes form a distinct, ancient, homeobox gene family, with highly conserved sequence and genomic organisation, albeit more divergent in Ciona. In amphioxus, no Dmbx expression is observed in the neural tube, supporting previous arguments that the MHB equivalent region has been secondarily modified in evolution. In Ciona, the CiDmbx gene is detected in neural cells caudal to Pax2/5/8-positive cells (MHB homologue), in the Hox-positive region, but, interestingly, not in any cells rostral to them. These results suggest that a midbrain homologue is missing in Ciona, and argue that midbrain development is a novelty that evolved specifically on the vertebrate lineage. We discuss the evolution of midbrain development in relation to the ancestry of the tripartite neural ground plan and the origin of the MHB organiser. (+info)Retroelement dynamics and a novel type of chordate retrovirus-like element in the miniature genome of the tunicate Oikopleura dioica. (6/153)
Retrotransposable elements have played an important role in shaping eukaryotic DNA, and their activity and turnover rate directly influence the size of genomes. With approximately 15,000 genes within 65-75 megabases, the marine tunicate Oikopleura dioica, a nonvertebrate chordate, has the smallest and most compact genome ever found in animals. Consistent with a massive elimination of retroelements, only one apparently novel clade of non-long terminal repeat (non-LTR) retrotransposons was detected within 41 megabases of nonredundant genomic sequences. In contrast, at least six clades of non-LTR elements were identified in the less compact genome of the tunicate Ciona intestinalis. Unexpectedly, Ty3/gypsy-related Tor LTR retrotransposons presented an astonishing level of diversity in O. dioica. They were generally poorly or apparently not corrupted, indicating recent activity. Both Tor3 and Tor4b families bore an envelope-like open reading frame, suggesting possible horizontal acquisition through infection. The Tor4b envelope-like gene might have been obtained from a paramyxovirus (RNA virus). Tor3 and Tor4b are phylogenetically clearly distinct from vertebrate retroviruses (Retroviridae) and are more reminiscent of certain insect and plant sequences. Tor elements potentially represent a so far unknown, ancient type of infectious retroelement in chordates. Their distribution and transmission dynamics in tunicates and other chordates deserve further study. (+info)Bayesian inference of the metazoan phylogeny; a combined molecular and morphological approach. (7/153)
Metazoan phylogeny remains one of evolutionary biology's major unsolved problems. Molecular and morphological data, as well as different analytical approaches, have produced highly conflicting results due to homoplasy resulting from more than 570 million years of evolution. To date, parsimony has been the only feasible combined approach but is highly sensitive to long-branch attraction. Recent development of stochastic models for discrete morphological characters and computationally efficient methods for Bayesian inference has enabled combined molecular and morphological data analysis with rigorous statistical approaches less prone to such inconsistencies. We present the first statistically founded analysis of a metazoan data set based on a combination of morphological and molecular data and compare the results with a traditional parsimony analysis. Interestingly, the Bayesian analyses demonstrate a high degree of congruence between morphological and molecular data, and both data sets contribute to the result of the combined analysis. Additionally, they resolve several irregularities obtained in previous studies and show high credibility values for controversial groups such as the ecdysozoans and lophotrochozoans. Parsimony, on the contrary, shows conflicting results, with morphology being congruent to the Bayesian results and the molecular data set producing peculiarities that are largely reflected in the combined analysis. (+info)Evolutionary relationships of Aurora kinases: implications for model organism studies and the development of anti-cancer drugs. (8/153)
BACKGROUND: As key regulators of mitotic chromosome segregation, the Aurora family of serine/threonine kinases play an important role in cell division. Abnormalities in Aurora kinases have been strongly linked with cancer, which has lead to the recent development of new classes of anti-cancer drugs that specifically target the ATP-binding domain of these kinases. From an evolutionary perspective, the species distribution of the Aurora kinase family is complex. Mammals uniquely have three Aurora kinases, Aurora-A, Aurora-B, and Aurora-C, while for other metazoans, including the frog, fruitfly and nematode, only Aurora-A and Aurora-B kinases are known. The fungi have a single Aurora-like homolog. Based on the tacit assumption of orthology to human counterparts, model organism studies have been central to the functional characterization of Aurora kinases. However, the ortholog and paralog relationships of these kinases across various species have not been rigorously examined. Here, we present comprehensive evolutionary analyses of the Aurora kinase family. RESULTS: Phylogenetic trees suggest that all three vertebrate Auroras evolved from a single urochordate ancestor. Specifically, Aurora-A is an orthologous lineage in cold-blooded vertebrates and mammals, while structurally similar Aurora-B and Aurora-C evolved more recently in mammals from a duplication of an ancestral Aurora-B/C gene found in cold-blooded vertebrates. All so-called Aurora-A and Aurora-B kinases of non-chordates are ancestral to the clade of chordate Auroras and, therefore, are not strictly orthologous to vertebrate counterparts. Comparisons of human Aurora-B and Aurora-C sequences to the resolved 3D structure of human Aurora-A lends further support to the evolutionary scenario that vertebrate Aurora-B and Aurora-C are closely related paralogs. Of the 26 residues lining the ATP-binding active site, only three were variant and all were specific to Aurora-A. CONCLUSIONS: In this study, we found that invertebrate Aurora-A and Aurora-B kinases are highly divergent protein families from their chordate counterparts. Furthermore, while the Aurora-A family is ubiquitous among all vertebrates, the Aurora-B and Aurora-C families in humans arose from a gene duplication event in mammals. These findings show the importance of understanding evolutionary relationships in the interpretation and transference of knowledge from studies of model organism systems to human cellular biology. In addition, given the important role of Aurora kinases in cancer, evolutionary analysis and comparisons of ATP-binding domains suggest a rationale for designing dual action anti-tumor drugs that inhibit both Aurora-B and Aurora-C kinases.

Water deer
Apart from mating during the rutting season, water deer are solitary animals, and males are highly territorial. Each buck marks out his territory with urine and feces. Sometimes a small pit is dug and it is possible that in digging, the male releases scent from the interdigital glands on its feet. The male also scent-marks by holding a thin tree in his mouth behind the upper canines and rubbing his preorbital glands against it. Males may also bite off vegetation to delineate territorial boundaries.[citation needed] Water deer use their tusks for territorial fights and are not related to carnivores. Confrontations between males begin with the animals walking slowly and stiffly towards each other, before turning to walk in parallel 10-20 m / 32-64 ft. apart, to assess one another. At this point, one male may succeed in chasing off his rival, making clicking noises during the pursuit. However, if the conflict is not resolved at the early stage, the bucks will fight. Each would try to wound the ...
Pickerel frog
The pickerel frog is a medium sized gray or tan frog marked with seven to twenty-one irregular rectangular dark brown spots which are oriented in two columns down its back.[3] The distinctive rectangular spots of the pickerel frog may blend together to form a long rectangle along the back. All leopard frogs have circular spots. In addition, pickerel frogs have prominent dorsolateral ridges that are unbroken. Another important distinguishing mark is the orange or yellow flash pattern found on the inner surface of the hind legs of pickerel frogs. The frog must be picked up to examine this, as the legs cover the coloration otherwise. The plains leopard frog (Lithobates blairi) exhibits this coloration as well, but the dorsolateral ridges are interrupted and inset medially in that species. The front toes of pickerel frogs are not webbed, a morphological characteristic for some frogs of the genus Rana and some frogs of the genus Lithobates. This allows pickerel frogs to be fit for terrestrial life. ...
Paranthropus boisei
The brain volume is quite small, about 500 to 550 cm3, not much larger than that of Australopithecus afarensis and Australopithecus africanus or modern-day chimpanzees. In P. boisei the foramen magnum is much shorter than in P. robustus. In addition, the cranial variation of P. boisei is remarkably high.[6] The adult males were larger on average than females (sexual dimorphism), as was the case in virtually all australopithecine species. Males weighed some 49 kg (108 lb) and stood about 1.37 m (4 ft 6 in) tall, while females weighed about 34 kg (75 lb) and were 1.24 m (4 ft 1 in) tall.[1] It had a skull highly specialized for heavy chewing and several traits seen in modern-day gorillas. The molar teeth were very large, with an area over twice that of modern humans.[7] The species is sometimes referred to as "Nutcracker Man" because it had the biggest, flattest cheek teeth and the thickest enamel of any known hominin.[8] P. boisei had large chewing muscles attached to a pronounced sagittal crest. ...
Brolga
... s are widespread and often abundant in north and north-east Australia, especially north-east Queensland, and are common as far south as Victoria. They are also found in southern New Guinea and as rare vagrants in New Zealand and the northern part of Western Australia. The population in northern Australia is estimated at between 20,000 and 100,000 birds and in southern Australia, 1,000 birds. The numbers of individuals in New Guinea are unknown.[10] Until 1961, Brolgas were thought to be the only species of crane in Australia, until the Sarus Crane was also located in Queensland.[12] Brolgas are non-migratory but move to different areas in response to seasonal rains and drying. In northern Australia, during the dry season (June to November), populations of brolgas are gregarious and largely occupy a strip of freshwater marshland up to 50 kilometres (31 mi) wide, lying between the coastal hills and the saline mangrove swamps that fringe the sea. They also visit freshwater lagoons in the ...

Eutheria
... (/juːˈθɪəriə/; from Greek εὐ-, eú- 'good, right' and θηρίον, thēríon 'beast'; lit. 'true beasts') is the clade consisting of all therian mammals that are more closely related to placentals than to marsupials. Eutherians are distinguished from noneutherians by various phenotypic traits of the feet, ankles, jaws and teeth. All extant eutherians lack epipubic bones, which are present in all other living mammals (marsupials and monotremes). This allows for expansion of the abdomen during pregnancy.[2] The oldest-known eutherian species is Juramaia sinensis, dated at 161 million years ago from the early Late Jurassic (Oxfordian) of China.[3] Eutheria was named in 1872 by Theodore Gill; in 1880 Thomas Henry Huxley defined it to encompass a more broadly defined group than Placentalia.[4] ...

Brown-cheeked fulvetta
The brown-cheeked fulvetta nests from January to June with a peak in January-February. In a study by Anoop Das and Vijayan, a total of 38 nests were found in 50,000 square metres. The nest is a cup, built with green moss, rootlets, lichen, leaves and grass lined with rootlets and placed in a fork or suspended from the twigs at a mean height of 68.21 cm from ground. Mean nest width was 91.8 mm and depth 48.7 mm.. Clutch size was two to three eggs and the incubation period is 10 ± 2 days and the nestling period is 12 ± 2 days. Hatching success was 55% while the nestling success was 32%. The most preferred plants for nesting were shrubs of the species Lasianthus ciliatus (36%) followed by the Saprosma fragrans (27%) and Thottea siliquosa (23%).. They tended to locate their nests at central position just near the main stem. A principal component analysis of the nest site variables showed nest height, concealment, plant height and canopy cover as the major parameters in nest site selection, ...
Homo habilis
It has generally been thought that brain size increased along the human line especially rapidly at the transition between species, with H. habilis brain size smaller than that of H. ergaster / H. erectus, jumping from about 600-650 cc (37-40 cu in) in H. habilis to about 900-1,000 cc (55-61 cu in) in H. ergaster and H. erectus.[25][23] However, a 2015 study showed that the brain sizes of H. habilis, H. rudolfensis, and H. ergaster generally ranged between 500-900 cc (31-55 cu in) after reappraising the brain volume of OH 7 from 647-687 cc (39.5-41.9 cu in) to 729-824 cc (44.5-50.3 cu in).[23] This does, nonetheless, indicate a jump from australopithecine brain size which generally ranged from 400-500 cc (24-31 cu in).[25] The brain anatomy of all Homo features an expanded cerebrum in comparison to australopithecines.

Atheris hispida
The males of this species grow to maximum total length of 73 cm (29 in): body 58 cm (23 in), tail 15 cm (5.9 in). Females grow to a maximum total length of 58 cm (23 in). The males are surprisingly long and slender compared to the females.[3]. The head has a short snout, more so in males than in females. The eyes are large and surrounded by 9-16 circumorbital scales. The orbits (eyes) are separated by 7-9 scales. The nostril is like a slit and separated from the eye by two scales. The eye and the supralabials are separated by a single row of scales. The supralabials number 7-10, of which the fourth is enlarged.[3] The body is covered with elongated, heavily keeled dorsal scales that give this animal a unique 'shaggy' idea to its skin, almost bristly appearance. The scales around the head and neck are the longest, decreasing posteriorly. Midbody, the dorsal scales are in 15-19 rows. There are 149-166 ventral scales and 35-64 subcaudals. The anal scale is single.[2][3]. ...
Bluespotted cornetfish
It is widespread in the tropical and subtropical waters of the Indo-Pacific as far north as Japan and east to the coasts of the Americas,[1] including the Red Sea.[3] In 2000, its presence was reported in the Mediterranean Sea; since then, it has continued to disperse and is now well established in some areas.[4] This species is considered as part of the Lessepsian migration.[5] It has spread rapidly through the Mediterranean from its origin in the Suez Canal, the first records being off Israel in 2000 and it had reached the southern coast of Spain[6] and as far north as the Gulf of Lions by 2007.[7] Scientists have determined that the fish in the Mediterranean are all descended from a small number of ancestors, possibly as a result of a single invasion event, and are not as genetically variable as their conspecifics in the Red Sea.[7] ...
Greater black krait
This species is medium in length, slender-bodied, and triangular in cross-section, with a short, pointed tail. It can grow to a maximum of about 1.3 m (4.3 ft), but adults usually average around 0.8 m (2.6 ft). The head is flat and slightly distinct from the neck. The eyes are small to medium in size, black with round pupils. Dorsal scales are smooth and glossy with scales of the vertebral row enlarged and hexagonal. Dorsal scale count is 15 - 15 - 15.[1] It is syntopic with the lesser black krait (Bungarus lividus), but can be separated by the enlarged dorsal vertebral scales. The number of ventral and subcaudals are higher than in all other Bungarus species (216-231 ventrals and 47-57 subcaudals).[2]. ...
Pygmy ringtail possum
Pseudochirulus mayeri is a very small species, with the males being slightly smaller than the females. The average female weight is 154.5 grams, ranging from 105 to 206 grams, while the average length is 372 mm with a range of 330-400 mm. The male weighs approximately 149 grams ranging between 115 and 178 grams and an average length of 344 mm with a range of 318-369 mm. Their life expectancy in the wild is approximately 4 or 5 years. These specific pygmy ringtails have "cinnamon brown to dark brown" fur with a visible "bluish-gray undercoat" when they move. Their tail has thick brown hair on top while calloused and hairless underneath. The Pseudochirulus mayeri also have "an opposable first toe on their hind feet, and their second and third toes are syndactylus."[3] These possums make dreys, or nests, "in the forks of trees, less than four meters off the ground."

Indian rhinoceros
The Rhinoceros Sutra is an early text in the Buddhist tradition, found in the Gandhāran Buddhist texts and the Pali Canon, as well as a version incorporated into the Sanskrit Mahavastu.[38] It praises the solitary lifestyle and stoicism of the Indian rhinoceros and is associated with the eremetic lifestyle symbolized by the Pratyekabuddha.[39] In the 3rd century, Philip the Arab exhibited an Indian rhinoceros in Rome. In 1515, Manuel I of Portugal obtained an Indian rhinoceros as a gift, which he passed on to Pope Leo X, but which died on the way from Lisboa to Rome. Three artistic representations were prepared of this rhinoceros: a woodcut by Hans Burgkmair dated to 1515, a drawing and a woodcut by Albrecht Dürer, also dated 1515. Latter is known as 'Dürer's Rhinoceros'. In about 1684, the first presumably Indian rhinoceros arrived in England.[40] George Jeffreys, 1st Baron Jeffreys spread the rumour that his chief rival Francis North, 1st Baron Guilford had been seen riding on it.[41] In ...
Pileated woodpecker
These birds mainly eat insects, especially carpenter ants and wood-boring beetle larvae. They also eat fruits, nuts, and berries, including poison ivy berries.[8] Pileated woodpeckers often chip out large and roughly rectangular holes in trees while searching out insects, especially ant colonies.[5] They also lap up ants by reaching with their long tongues into crevices. They are self-assured on the vertical surfaces of large trees, but can seem awkward while feeding on small branches and vines. Pileated woodpeckers may also forage on or near the ground, especially around fallen, dead trees, which can contain a variety of insect life. They may forage around the sides of human homes or even cars, and can occasionally be attracted to suet-type feeders. Although they are less likely feeder visitors than smaller woodpeckers, pileateds may regularly be attracted to them in areas experiencing harsh winter conditions.. Usually, pileated woodpeckers excavate their large nests in the cavities of dead ...
Osteostraci
The class Osteostraci ("Bony Shields") is an extinct taxon of bony-armored jawless fish, termed "ostracoderms", that lived in what is now North America, Europe and Russia from the Middle Silurian to Late Devonian. Anatomically speaking, the osteostracans, especially the Devonian species, were among the most advanced of all known agnathans. This is due to the development of paired fins, and their complicated cranial anatomy. The osteostracans were more similar to lampreys than to jawed vertebrates in possessing two pairs of semicircular canals in the inner ear, as opposed to the three pairs found in the inner ears of jawed vertebrates. They are thought to be the sister-group to pituriaspids, and together, these two taxa of jawless vertebrates are the sister-group of gnathostomes. Several synapomorphies support this hypothesis, such as the presence of: sclerotic ossicles, paired pectoral fins, a dermal skeleton with three layers (a basal layer of isopedin, a middle layer of spongy bone, and a ...
Kangaroo rat
... s are primarily seed eaters.[10] They will, however, sometimes eat vegetation at some times of the year and some insects, too.[3] They have been seen storing the seeds of mesquite, creosote, bush, purslane, ocotillo and grama grass in their cheek pouches. Kangaroo rats will store extra seeds in seed caches.[8] This caching behavior affects the range-land and croplands where the animals live.[3] Kangaroo rats must harvest as much seed as possible in as little time as possible.[10] To conserve energy and water, they minimize their time away from their cool, dry burrows. In addition, maximizing time in their burrows minimizes their exposure to predators.[10] When on foraging trips, kangaroo rats hoard the seeds that they find. It is important for a kangaroo rat to encounter more food items than are consumed, at least at one point in the year, as well as defend or rediscover food caches and remain within the same areas long enough to utilize food resources.[7] Different species of ...

Crab-eating fox
The crab-eating fox is predominantly greyish-brown, with areas of red on the face and legs, and black-tipped ears and tail. It has short, strong legs and its tail is long and bushy. It may reach an adult weight of 10 to 17 pounds (4.5 to 7.7 kg). The head and body length averages 64.3 centimetres (25.3 in), and the average tail length is 28.5 centimetres (11.2 in).[9] This fox weighs between 10 to 17 pounds (4.5 to 7.7 kg).[10][11] It is mainly nocturnal and also is active at dusk, spending its day in dens that were dug by other animals. It either hunts individually or lives in pairs; it eats crabs, lizards and different flying animals. It is easy to domesticate and farm, but its fur is not so highly valued as that of other species. The coat is short and thick. Coloration varies from grey to brown, to yellowish, to pale, to dark grey. There is a black streak along the back legs, with a black stripe along the spine. On muzzle, ears and paws there is more-reddish fur. The tail, legs and ear tips ...
Mexican wolf
The Mexican wolf was listed as endangered under the U.S. Endangered Species Act in 1976, with the Mexican Wolf Recovery Team being formed three years later by the United States Fish and Wildlife Service. The Recovery Team composed the Mexican Wolf Recovery Plan, which called for the reestablishment of at least 100 wolves in their historic range through a captive breeding program. Between 1977 and 1980, four males and a pregnant female were captured in Durango and Chihuahua in Mexico to act as founders of a new "certified lineage". By 1999, with the addition of new lineages, the captive Mexican wolf population throughout the US and Mexico reached 178 individuals. These captive-bred animals were subsequently released into the Apache National Forest in eastern Arizona, and allowed to recolonize east-central Arizona and south-central New Mexico, areas which were collectively termed the Blue Range Wolf Recovery Area (BRWRA). The Recovery Plan called for the release of additional wolves in the White ...
Speckled mousebird
This bird is about 35 cm (14 inches) long, with the tail comprising approximately half the length, and weighs about 57 grams (2 oz). It is well-named, because it is dull-mousy brown in overall color on the back and on the head (including a prominent crest). The bill is black on the upper part and is a pinkish color on the lower part. The rare white-headed mousebird can be confused with this species, but the differently colored mandibles and the lack of a bare grey orbital patch render the Speckled species distinctive.[2] The speckled mousebird is not known for its voice, as songbirds are, although it is a noisy creature. They make a warbling tsu-tsu call while in flight, and are known for their tisk-tisk alarm call while in flight.[2] ...
