Sylvilagus Palustris Hefneri
''Sylvilagus palustris hefneri'', also known as the Lower Keys marsh rabbit, is an endangered subspecies of marsh rabbit named after ''Playboy'' founder Hugh Hefner. General ''Sylvilagus palustris hefneri'' was federally recognized as an endangered species on June 21, 1990. The urbanized Florida Keys have left the rabbits with a very small home range, making them more vulnerable to threats such as pollution, vehicular road kill, and predation by stray cats. Forys and Humphrey (1999) predicted a gradual decline in ''S. p. hefneri'' abundance and extinction within 50 years (of 1995).Forys, E.A., and S.R. Humphrey. 1994.

Endangered
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when assessing the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conocarpus Erectus
''Conocarpus erectus'', commonly called buttonwood or button mangrove, is a mangrove shrub in the family Combretaceae. This species grows on shorelines in tropical and subtropical regions around the world. Range Locations it is known from include Florida, Bermuda, the Bahamas, the Caribbean, Central and South America from Mexico to Brazil on the Atlantic Coast and Mexico to Ecuador on the Pacific Coast, western Africa and in Melanesia and Polynesia. It was introduced in Kuwait because it can thrive in high temperatures and absorbs brackish water. Description ''Conocarpus erectus'' is usually a dense multiple-trunked shrub, tall, but can grow into a tree up to or more tall, with a trunk up to in diameter. The United States National Champion green buttonwood is tall, has a spread of , and a circumference of . The bark is thick and has broad plates of thin scales which are gray to brown.

Sylvilagus
Cottontail rabbits are the leporid species in the genus ''Sylvilagus'', found in the Americas. Most ''Sylvilagus'' species have stub tails with white undersides that show when they retreat, giving them their characteristic name. However, this feature is not present in all cottontails nor is it unique to the genus. The genus is widely distributed across North America, Central America and northern and central South America, though most species are confined to some particular regions. Most species live in nests called forms, and all have altricial young. An adult female averages three litters per year, which can occur in any season; occurrence, and litter size depend on several factors including time of the year, weather, and location. The average litter size is four but can range from as few as two to as many as eight, most of whom do not go on to survive to adulthood. Cottontail rabbits show a greater resistance to myxomatosis than European rabbits. Evolution Cottontails ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Organisms Named After Famous People (born 1900–1949)
In biological nomenclature, organisms often receive scientific names that honor a person. A taxon (e.g. species or genus; plural: taxa) named in honor of another entity is an eponym, eponymous taxon, and names specifically honoring a person or persons are known as patronym (taxonomy), patronyms. Scientific names are generally formally published in peer-reviewed journal articles or larger monographs along with descriptions of the named taxa and ways to distinguish them from other taxa. Following rules of Latin grammar, species or subspecies names derived from a man's name often end in ''-i'' or ''-ii'' if named for an individual, and ''-orum'' if named for a group of men or mixed-sex group, such as a family. Similarly, those named for a woman often end in ''-ae'', or ''-arum'' for two or more women. This list is part of the List of organisms named after famous people, and includes organisms named after famous individuals born between 1 January 1900 and 31 December 1949. It also incl ...

Wildlife Corridor
A wildlife corridor, habitat corridor, or green corridor is an area of habitat connecting wildlife populations separated by human activities or structures (such as roads, development, or logging). This allows an exchange of individuals between populations, which may help prevent the negative effects of inbreeding and reduced genetic diversity (via genetic drift) that often occur within isolated populations. Corridors may also help facilitate the re-establishment of populations that have been reduced or eliminated due to random events (such as fires or disease). This may potentially moderate some of the worst effects of habitat fragmentation, wherein urbanization can split up habitat areas, causing animals to lose both their natural habitat and the ability to move between regions to use all of the resources they need to survive. Habitat fragmentation due to human development is an ever-increasing threat to biodiversity, and habitat corridors are a possible mitigation. Purpose Th ...

Reticulated Python
The reticulated python (''Malayopython reticulatus'') is a python species native to South and Southeast Asia. It is the world's longest snake, and is among the three heaviest. It is listed as least concern on the IUCN Red List because of its wide distribution. In several countries in its range, it is hunted for its skin, for use in traditional medicine, and for sale as pets. It is an excellent swimmer, has been reported far out at sea, and has colonized many small islands within its range. Like all pythons, it is a non-venomous constrictor. Adult humans have been killed (and in at least two reported cases, eaten) by reticulated pythons. Taxonomy The reticulated python was first described in 1801 by German naturalist Johann Gottlob Theaenus Schneider, who described two zoological specimens held by the Göttingen Museum in 1801 that differed slightly in colour and pattern as separate species—''Boa reticulata'' and ''Boa rhombeata''. The specific name, ''reticulatus'', is Lat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ball Python
The ball python (''Python regius''), also called the royal python, is a python species native to West and Central Africa, where it lives in grasslands, shrublands and open forests. This nonvenomous constrictor is the smallest of the African pythons, growing to a maximum length of . The name "ball python" refers to its tendency to curl into a ball when stressed or frightened. Taxonomy ''Boa regia'' was the scientific name proposed by George Shaw in 1802 for a pale variegated python from an indistinct place in Africa. The generic name ''Python'' was proposed by François Marie Daudin in 1803 for non-venomous flecked snakes. Between 1830 and 1849, several generic names were proposed for the same zoological specimen described by Shaw, including ''Enygrus'' by Johann Georg Wagler, ''Cenchris'' and ''Hertulia'' by John Edward Gray. Gray also described four specimens that were collected in Gambia and were preserved in spirits and fluid. Description The ball python is black, or ...

Boa Constrictor
The boa constrictor (scientific name also ''Boa constrictor''), also called the red-tailed boa, is a species of large, non-venomous, heavy-bodied snake that is frequently kept and bred in captivity. The boa constrictor is a member of the family Boidae, found in tropical South America, as well as some islands in the Caribbean. A staple of private collections and public displays, its color pattern is highly variable yet distinctive. Four subspecies are currently recognized. This article focuses on the species ''Boa constrictor'' as a whole, and on the nominate subspecies ''B. c. constrictor''. Common names Though all boids are constrictors, only this species is properly referred to as a "boa constrictor"—a rare instance of an animal having the same common English name and scientific binomial name. All subspecies are referred to as "boa constrictors", and are part of a diverse group of New World boas referred to as "red-tailed" boas, comprising species of both ''Boa constrictor' ...

Gambian Pouched Rat
The Gambian pouched rat (''Cricetomys gambianus''), also Common name, commonly known as the African giant pouched rat, is a species of nocturnal pouched rat of the giant pouched rat genus ''Cricetomys'', in the Family (biology), family Nesomyidae. It is among the largest Muroidea, muroids in the world, growing to about long, including the tail, which makes up half of its total length. It is widespread in Sub-Saharan Africa, ranging from Senegal to Kenya and from Angola to Mozambique (although it is absent from much of the Democratic Republic of the Congo, where Emin's Pouched Rat, Emin's pouched rat is present) from sea level to . The Gambian pouched rat is sometimes kept as a pet, but some have escaped from captivity and become an invasive species in Florida. In the United States, the Centers for Disease Control and Prevention (CDC) and the Food and Drug Administration (FDA) now ban the importation of this species because it is blamed for the 2003 Midwest monkeypox outbreak, 200 ...

Invasive Species
An invasive species otherwise known as an alien is an introduced organism that becomes overpopulated and harms its new environment. Although most introduced species are neutral or beneficial with respect to other species, invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food webfor example the purple sea urchin (''Strongylocentrotus purpuratus'') which has decimated kelp forests along the northern California coast due to overharvesting of its natural predator, the California sea otter (''Enhydra lutris''). Since the 20th century, invasive species have become a serious economic, social, and environmental threat. Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range of ...

Sea Level Rise
Globally, sea levels are rising due to human-caused climate change. Between 1901 and 2018, the globally averaged sea level rose by , or 1–2 mm per year on average.IPCC, 2019Summary for Policymakers InIPCC Special Report on the Ocean and Cryosphere in a Changing Climate .-O. Pörtner, D.C. Roberts, V. Masson-Delmotte, P. Zhai, M. Tignor, E. Poloczanska, K. Mintenbeck, A. Alegría, M. Nicolai, A. Okem, J. Petzold, B. Rama, N.M. Weyer (eds.) Cambridge University Press, Cambridge, UK and New York, NY, USA. https://doi.org/10.1017/9781009157964.001. This rate is accelerating, with sea levels now rising by 3.7 mm per year. Climate scientists expect further acceleration during the 21st century. Climate change heats (and therefore expands) the ocean and melts land-based ice sheets and glaciers. Between 1993 and 2018, the thermal expansion of water contributed 42% to sea level rise; melting of temperate glaciers, 21%; Greenland, 15%; and Antarctica, 8%. Over the next 2 ...
