Scalopus Aquaticus
The eastern mole or common mole (''Scalopus aquaticus'') is a medium-sized North American mole. It is the only species in the genus ''Scalopus''. It is found in forested and open areas with moist sandy soils in northern Mexico, the eastern United States and the southwestern corner of Ontario in Canada. The eastern mole has grey-brown fur with silver-grey underparts, a pointed nose and a short tail. It is about in length including a long tail and weighs about . Its front paws are broad and spade-shaped, specialized for digging. It has 36 teeth. Its eyes are covered by fur and its ears are not visible. The eastern mole spends most of its time underground, foraging in shallow burrows for earthworms, grubs, beetles, insect larvae and some plant matter. It is active year-round. It is mainly solitary except during mating in early spring. The female has a litter of two to five young in a deep burrow. In Canada, the eastern mole is limited to about 2,600 acres in southern Ontario, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Étienne Geoffroy Saint-Hilaire
Étienne Geoffroy Saint-Hilaire (; 15 April 177219 June 1844) was a French naturalist who established the principle of "unity of composition". He was a colleague of Jean-Baptiste Lamarck and expanded and defended Lamarck's evolutionary theories. Geoffroy's scientific views had a transcendental flavor (unlike Lamarck's materialistic views) and were similar to those of German morphologists like Lorenz Oken. He believed in the underlying unity of organismal design, and the possibility of the transmutation of species in time, amassing evidence for his claims through research in comparative anatomy, paleontology, and embryology. He is considered as a predecessor of the evo-devo evolutionary concept. Life and early career Geoffroy was born at Étampes (in present-day Essonne), and studied at the Collège de Navarre, in Paris, where he studied natural philosophy under M. J. Brisson. He then attended the lectures of Louis-Jean-Marie Daubenton at the College de France and Fourcroy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Foraging
Foraging is searching for wild food resources. It affects an animal's fitness because it plays an important role in an animal's ability to survive and reproduce. Foraging theory is a branch of behavioral ecology that studies the foraging behavior of animals in response to the environment where the animal lives. Behavioral ecologists use economic models and categories to understand foraging; many of these models are a type of optimal model. Thus foraging theory is discussed in terms of optimizing a payoff from a foraging decision. The payoff for many of these models is the amount of energy an animal receives per unit time, more specifically, the highest ratio of energetic gain to cost while foraging. Foraging theory predicts that the decisions that maximize energy per unit time and thus deliver the highest payoff will be selected for and persist. Key words used to describe foraging behavior include ''resources'', the elements necessary for survival and reproduction which have a l ...

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 ...

Fauna Of The Southeastern United States
Fauna (: faunae or faunas) is all of the animal life present in a particular region or time. The corresponding terms for plants and fungi are ''flora'' and ''funga'', respectively. Flora, fauna, funga and other forms of life are collectively referred to as '' biota''. Zoologists and paleontologists use ''fauna'' to refer to a typical collection of animals found in a specific time or place, e.g. the "Sonoran Desert fauna" or the "Burgess Shale fauna". Paleontologists sometimes refer to a sequence of faunal stages, which is a series of rocks all containing similar fossils. The study of animals of a particular region is called faunistics. Etymology ''Fauna'' comes from the name Fauna, a Roman goddess of earth and fertility, the Roman god Faunus, and the related forest spirits called Fauns. All three words are cognates of the name of the Greek god Pan, and ''panis'' is the Modern Greek equivalent of fauna (πανίς or rather πανίδα). ''Fauna'' is also the word for a boo ...

Taxa Named By Carl Linnaeus
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammals Described In 1758
A mammal () is a vertebrate animal of the Class (biology), class Mammalia (). Mammals are characterised by the presence of milk-producing mammary glands for feeding their young, a broad neocortex region of the brain, fur or hair, and three Evolution of mammalian auditory ossicles, middle ear bones. These characteristics distinguish them from reptiles and birds, from which their ancestors Genetic divergence, diverged in the Carboniferous Period over 300 million years ago. Around 6,640 Neontology#Extant taxon, extant species of mammals have been described and divided into 27 Order (biology), orders. The study of mammals is called mammalogy. The largest orders of mammals, by number of species, are the rodents, bats, and eulipotyphlans (including hedgehogs, Mole (animal), moles and shrews). The next three are the primates (including humans, monkeys and lemurs), the Artiodactyl, even-toed ungulates (including pigs, camels, and whales), and the Carnivora (including Felidae, ...

Hantavirus Pulmonary Syndrome
Hantavirus pulmonary syndrome (HPS), also called hantavirus cardiopulmonary syndrome (HCPS), is a severe respiratory disease caused by hantaviruses. The main features of illness are microvascular leakage and acute respiratory distress syndrome. Symptoms occur anywhere from one to eight weeks after exposure to the virus and come in three distinct phases. First, there is an early phase with flu-like symptoms such as fever, muscle aches, headache, and shortness of breath, as well as low platelet count. Second, there is cardiopulmonary phase during which people experience elevated or irregular heart rate, cardiogenic shock, and pulmonary capillary leakage, which can lead to respiratory failure, low blood pressure, and buildup of fluid in the lungs and chest cavity. The final phase is recovery, which typically takes months, but difficulties with breathing can persist for up to two years. The disease has a case fatality rate of 30 to 60 percent. Death usually occurs suddenly during the c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rockport Virus
Rockport virus (RKPV) is a single-stranded, enveloped, negative-sense RNA orthohantavirus. Natural reservoir Rockport virus was first isolated in archival tissues of four Eastern moles found in and around Rockport, Texas. Virology Phylogenetic analysis shows Rockport virus clusters geographically with Andes virus (ANDV) and Sin Nombre virus (SNV), both of which are carried by sigmodontine and Neotominae rodents. It shares the same S and the L genomic-segment with Puumala virus (PUUV), Tula virus (TULV), and Prospect Hill virus (PHV).Arai S., et al.

Englewood, Florida
Englewood is a census-designated place (CDP) in Charlotte and Sarasota counties in the U.S. state of Florida. As of the 2020 census, it had a population of 20,800, up from 14,863 at the 2010 census. It is part of the North Port-Bradenton-Sarasota, Florida Metropolitan Statistical Area. History Archeological digs in what is now Englewood discovered ceramics belonging to both the Weeden Island culture and Safety Harbor culture. One of the earliest white settlers in the area was William Goff, who arrived by schooner from Tampa in 1878. He settled a piece of land a few miles south of where Englewood would be platted. On July 3, 1895, a post office was established in the area as well. The Great Freeze of 1894 and 1895, along with a bad freeze in 1896, led to the decimation of many local orange plants. For this reason, by 1897, a Manatee County General Directory listed fish as the chief product for Englewood.Deming, et al (1990). p. 123. The original plat of Englewood was recor ...

Anastasia Island
Anastasia Island is a barrier island located off the northeast Atlantic coast of Florida in the United States. It sits east of St. Augustine, running north–south in a slightly southeastern direction to Matanzas Inlet. The island is about long and an average of 1 mile in width. It is separated from the mainland by the Matanzas River, part of the Intracoastal waterway. Matanzas Bay, the body of water between the island and downtown St. Augustine, opens into St. Augustine Inlet. Part of the island (the Davis Shores and Lighthouse Park neighborhoods) is within St. Augustine city limits, while other communities on the island include St. Augustine Beach, Coquina Gables, Butler Beach, Crescent Beach, and Treasure Beach. Fort Matanzas National Monument, a Spanish colonial-era fort built in 1740–1742, is located at the southern end of the island on Rattlesnake Island in the Intracoastal waterway within the park boundaries; it was designed to protect St. Augustine from atta ...

Beetle
Beetles are insects that form the Taxonomic rank, order Coleoptera (), in the superorder Holometabola. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described arthropods and 25% of all known animal species; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. However, the number of beetle species is challenged by the number of species in Fly, dipterans (flies) and hymenopterans (wasps). Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae (ladybirds or ...

Earthworm
An earthworm is a soil-dwelling terrestrial invertebrate that belongs to the phylum Annelida. The term is the common name for the largest members of the class (or subclass, depending on the author) Oligochaeta. In classical systems, they were in the order of Opisthopora since the male pores opened posterior to the female pores, although the internal male segments are anterior to the female. Theoretical cladistic studies have placed them in the suborder Lumbricina of the order Haplotaxida, but this may change. Other slang names for earthworms include "dew-worm", "rainworm", "nightcrawler", and "angleworm" (from its use as angling hookbaits). Larger terrestrial earthworms are also called megadriles (which translates to "big worms") as opposed to the microdriles ("small worms") in the semiaquatic families Tubificidae, Lumbricidae and Enchytraeidae. The megadriles are characterized by a distinct clitellum (more extensive than that of microdriles) and a vascular system ...
