Mexican Gray Squirrel
The Mexican gray squirrel (or red-bellied squirrel) (''Sciurus aureogaster'') is a tree squirrel in the genus ''Sciurus'' native to Guatemala and eastern and southern Mexico. It has been introduced to the Florida Keys. The alternate name should not be confused with the Indonesian red-bellied squirrel (''Rubrisciurus rubriventer'') or the Asian red-bellied tree squirrel (''Callosciurus erythraeus''). Behaviour Since the introduction of the species to Florida in the late 1930s, its nesting locations have become more irregular, nesting in varying species of trees and even choosing to nest in hurricane debris. Ecology ''Sciurus aureogaster'' has had an extremely negative impact on ''Thrinax radiata'' populations on Elliot Key. It uses palm fibers as nesting materials and consumes the palm itself, often killing the plant. Subspecies The two subspecies each have many synonyms associated with them: * The subspecies ''S. a. aureogaster'' was also known as ''S. a. chrysogaster'', ''S ...

Frédéric Cuvier
Georges-Frédéric Cuvier (28 June 1773 – 24 July 1838) was a French zoologist and paleontologist. He was the younger brother of noted naturalist and zoologist Georges Cuvier. Career Frederic was the head keeper of the menagerie at the Muséum d'Histoire Naturelle in Paris from 1804 to 1838. He named the red panda (''Ailurus fulgens'') in 1825. The chair of comparative physiology was created for him at the Muséum d'Histoire Naturelle in 1837. He was elected as a foreign member of the Royal Society in 1835. He is mentioned in Charles Darwin's ''On the Origin of Species'' (Chapter VII) as having worked on animal behaviour and instinct, especially the distinction between habit and instinct. He is also mentioned in Herman Melville's ''Moby-Dick'' (Chapter 32) as having written on the topic of whales. Evolution Cuvier has been described as the first scientist to use terms ''"héréditaire"'' (hereditary) in 1807 and "heredity” in 1812 in their now biological context. He used b ...

Red-bellied Tree Squirrel
Pallas's squirrel (''Callosciurus erythraeus''), also known as the red-bellied tree squirrel, is a species of squirrel native to Greater China, India, and Southeast Asia. Description Pallas's squirrel is a medium-sized tree squirrel, with a head-body length of , and a tail in length. Both sexes are of similar size and appearance, and weigh between . The colour of the pelt varies considerably between the many different subspecies, but is generally brownish on the upper body with a more reddish tint on the belly, and often with some black on the tail. The precise pattern and shades of the fur are often used to distinguish subspecies from one another, but make it difficult to distinguish the species as a whole from other, similarly variable, tree squirrel species. Subspecies Over 30 subspecies have been identified, although not all are recognised by all authorities: * ''C. e. erythraeus'' * ''C. e. atrodorsalis'' * ''C. e. bartoni'' * ''C. e. bhutanensis'' * ''C. e. bonhot ...

Mammals Described In 1829
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla ( cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together w ...

Rodents Of North America
Rodents (from Latin , 'to gnaw') are mammals of the order Rodentia (), which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for New Zealand, Antarctica, and several oceanic islands, though they have subsequently been introduced to most of these land masses by human activity. Rodents are extremely diverse in their ecology and lifestyles and can be found in almost every terrestrial habitat, including human-made environments. Species can be arboreal, fossorial (burrowing), saltatorial/richochetal (leaping on their hind legs), or semiaquatic. However, all rodents share several morphological features, including having only a single upper and lower pair of ever-growing incisors. Well-known rodents include mice, rats, squirrels, prairie dogs, porcupines, beavers, guinea pigs, and hamsters. Rabbits, hares, and pikas, whose ...

Mammals Of Mexico
This is a list of the native wild mammal species recorded in Mexico. As of September 2014, there were 536 mammalian species or subspecies listed. Based on International Union for Conservation of Nature, IUCN data, Mexico has 23% more noncetacean mammal species than the U.S. and Canada combined in an area only 10% as large, or a species density over 12 times that of its northern neighbors. Mexico's high mammal biodiversity is in part a reflection of the wide array of biomes present over its latitudinal, climatic and altitudinal ranges, from lowland tropical rainforest to temperate desert to montane forest to alpine tundra. The general increase in terrestrial biodiversity moving towards the equator is another important factor in the comparison. Mexico includes much of the Mesoamerica#Biodiversity, Mesoamerican and Madrean pine-oak woodlands biodiversity hotspots. From a biogeographic standpoint, most of Mexico is linked to the rest of North America as part of the Nearctic realm. Howeve ...

Thrinax Radiata
''Thrinax radiata'', also known as the Florida thatch palm, is a medium to slow growing palm in the family Arecaceae. It is native to many Caribbean islands, Mexico, Central America, and far southern Florida. Its natural habitat is sandy, calcareous soil in coastal areas. Description Like all palms, this species grows thick and low to the ground before sending its meristem vertical, gaining the form of a slender tree. This species has no crownshaft and the canopy appears to emerge directly from the trunk. On average this species reaches a height of 20 feet. It has large compoundly segmented leaves which are 4 to 5 feet wide and 2.5 feet long. The leaves are palmate and divide into segments about halfway down their length with the leaf emerging from the petiole in what is described as a pointed hastula shape. The entire canopy consists of between 10 and 20 large leaves and on average gains only 6 inches of height per year. The shape of the canopy varies depending on its amount of i ...

Red-bellied Squirrel
The red-bellied squirrel or Sulawesi giant squirrel (''Rubrisciurus rubriventer'') is a species of squirrel. Until recently, it was described as a species in the genus ''Callosciurus'', but since the 1990s it is generally placed in its own genus ''Rubrisciurus''. It is endemic on the Indonesian island of Sulawesi, where it is widespread. It has also been found on Sangir Island Sangir Besar, commonly called Sangir Island (with the spelling variants "Sangihe", "Sanghir" or "Sangi"), is an island in the Sangir Islands group. Its Indonesian name literally means "Great Sangir", in reference to the fact that it is the archip ... to the north of Sulawesi. With a length of 25 cm (head and body), it is rather large for a squirrel. It lives in the tree tops of the rainforests of the island. References *Thorington, R. W. Jr. and R. S. Hoffman. 2005.

Tree Squirrel
Tree squirrels are the members of the squirrel Family (biology), family (Sciuridae) commonly just referred to as "squirrels." They include more than 100 arboreal species native to all continents except Antarctica and Oceania. They do not form a single natural, or monophyly, monophyletic, group; they are variously related to others in the squirrel family, including ground squirrels, flying squirrels, marmots, and chipmunks. The defining characteristic used to determine which species of Sciuridae are tree squirrels is dependent on their habitat rather than their physiology. Tree squirrels live mostly among trees, as opposed to those that live in burrows in the ground or among rocks. An exception is the flying squirrel that also makes its home in trees, but has a physiological distinction separating it from its tree squirrel cousins: special flaps of skin called patagia, acting as glider wings, which allow gliding flight. The best known genus of tree squirrels is ''Sciurus'', which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Florida Keys
The Florida Keys are a coral cay archipelago located off the southern coast of Florida, forming the southernmost part of the continental United States. They begin at the southeastern coast of the Florida peninsula, about south of Miami, and extend in a gentle arc south-southwest and then westward to Key West, the westernmost of the inhabited islands, and on to the uninhabited Dry Tortugas. The islands lie along the Florida Straits, dividing the Atlantic Ocean to the east from the Gulf of Mexico to the northwest, and defining one edge of Florida Bay. At the nearest point, the southern part of Key West is just from Cuba. The Florida Keys are between about 24.3 and 25.5 degrees North latitude. More than 95 percent of the land area lies in Monroe County, but a small portion extends northeast into Miami-Dade County, such as Totten Key. The total land area is . As of the 2010 census the population was 73,090 with an average density of , although much of the population is concent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
