Southern Ribbon Snake
The southern ribbon snake ''(Thamnophis saurita sackenii''), also known commonly as the peninsula ribbon snake and the Florida ribbon snake, is a subspecies of garter snake in the family Colubridae. It is one of four subspecies of the ribbon snake (''Thamnophis saurita''). Etymology The subspecific name, ''sackenii'', is in honor of Russian entomologist Carl Robert Romanovich von der Osten-Sacken. Geographic range The southern ribbon snake occurs in the southeastern United States in extreme southern South Carolina, southeastern Georgia, and peninsular Florida, at elevations from sea level to .

Robert Kennicott
Robert Kennicott (November 13, 1835 – May 13, 1866) was an American naturalist and herpetologist. Chronic illness kept Kennicott out of school as a child. Instead, Kennicott spent most of his time outdoors, collecting plants and animals. His father schooled him at home and convinced naturalist Jared Potter Kirtland to take him as an understudy. Soon, Kennicott was providing specimens for the Smithsonian Institution via assistant secretary Spencer Fullerton Baird. Kennicott advocated for the study and protection of native prairie animals in an era when farmers sought to eradicate them. He teamed with Northwestern University to found a natural history museum in 1857, then founded the Chicago Academy of Sciences. While in Chicago he served as a mentor to several young naturalists, including William Healey Dall. He joined the Megatherium Club and studied specimens in Hudson Bay. The Western Union Telegraph Expedition commissioned Kennicott as a scientist for their excursion in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hobart Muir Smith
Hobart Muir Smith, born Frederick William Stouffer (September 26, 1912 – March 4, 2013), was an American herpetologist. He is credited with describing more than 100 new species of American reptiles and amphibians. In addition, he has been honored by having at least six species named after him, including the southwestern blackhead snake (''Tantilla hobartsmithi)'', Smith's earth snake (''Uropeltis grandis''), Smith's arboreal alligator lizard (''Abronia smithi)'', Hobart's anadia ('' Anadia hobarti)'', Hobart Smith's anole ('' Anolis hobartsmithi)'', and Smith's rose-bellied lizard ('' Sceloporus smithi'')''. At 100 years of age, Smith continued to be an active and productive herpetologist. Although he published on a wide range of herpetological subjects, his main focus throughout his career was on the amphibians and reptiles of Mexico, including taxonomy, bibliographies, and history. Having published more than 1,600 manuscripts, he surpassed all contemporaries and remai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Delbert Dwight Davis
Delbert Dwight Davis (in literature, usually just D. Dwight Davis), (30 December 1908 – 6 February 1965) was an American comparative anatomist and curator of zoology at the Chicago Natural History Museum. Davis was born in Rockford, Illinois and was educated at North Central College, Naperville. In 1930, he joined the Chicago Natural History Museum as an assistant in osteology under Wilfred Osgood. He became a curator of anatomy in 1941. He published on a range of zoological taxa from insects to mammals. He took a special interest in identifying the evolutionary relationships of the giant panda to other mammals using anatomical studies. He took over 25 years on the study and published a comprehensive book on the topic just a couple of months before his death. He visited Borneo in 1950 on a collection expedition and visited Malaya in 1962 where he worked for 9 months at the University in Kuala Lumpur.

John L
John Lasarus Williams (29 October 1924 – 15 June 2004), known as John L, was a Welsh nationalist activist. Williams was born in Llangoed on Anglesey, but lived most of his life in nearby Llanfairpwllgwyngyll. In his youth, he was a keen footballer, and he also worked as a teacher. His activism started when he campaigned against the refusal of Brewer Spinks, an employer in Blaenau Ffestiniog, to permit his staff to speak Welsh. This inspired him to become a founder of Undeb y Gymraeg Fyw, and through this organisation was the main organiser of ''Sioe Gymraeg y Borth'' (the Welsh show for Menai Bridge using the colloquial form of its Welsh name).Colli John L Williams , '''', 15 June ...

Ovoviviparity
Ovoviviparity, ovovivipary, ovivipary, or aplacental viviparity is a term used as a "bridging" form of reproduction between egg-laying oviparous and live-bearing viviparous reproduction. Ovoviviparous animals possess embryos that develop inside eggs that remain in the mother's body until they are ready to hatch. The young of some ovoviviparous amphibians, such as ''Limnonectes larvaepartus'', are born as larvae, and undergo further metamorphosis outside the body of the mother. Members of genera ''Nectophrynoides'' and ''Eleutherodactylus'' bear froglets, not only the hatching, but all the most conspicuous metamorphosis, being completed inside the body of the mother before birth. Among insects that depend on opportunistic exploitation of transient food sources, such as many Sarcophagidae and other carrion flies, and species such as many Calliphoridae, that rely on fresh dung, and parasitoids such as tachinid flies that depend on entering the host as soon as possible, the e ...

Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arboreal
Arboreal locomotion is the Animal locomotion, locomotion of animals in trees. In habitats in which trees are present, animals have evolved to move in them. Some animals may scale trees only occasionally, but others are exclusively arboreal. The habitats pose numerous mechanical challenges to animals moving through them and lead to a variety of anatomical, behavioral and ecological consequences as well as variations throughout different species.Cartmill, M. (1985). Climbing. In ''Functional Vertebrate Morphology'', eds. M. Hildebrand D. M. Bramble K. F. Liem and D. B. Wake, pp. 73–88. Cambridge: Belknap Press. Furthermore, many of these same principles may be applied to climbing without trees, such as on rock piles or mountains. Some animals are exclusively arboreal in habitat, such as the tree snail. Biomechanics Arboreal habitats pose numerous mechanical challenges to animals moving in them, which have been solved in diverse ways. These challenges include moving on n ...

Stream
A stream is a continuous body of water, body of surface water Current (stream), flowing within the stream bed, bed and bank (geography), banks of a channel (geography), channel. Depending on its location or certain characteristics, a stream may be referred to by a variety of local or regional names. Long large streams are usually called rivers, while smaller, less voluminous and more intermittent river, intermittent streams are known as streamlets, brooks or creeks. The flow of a stream is controlled by three inputs – surface runoff (from precipitation or meltwater), daylighting (streams), daylighted subterranean river, subterranean water, and surfaced groundwater (Spring (hydrology), spring water). The surface and subterranean water are highly variable between periods of rainfall. Groundwater, on the other hand, has a relatively constant input and is controlled more by long-term patterns of precipitation. The stream encompasses surface, subsurface and groundwater fluxes th ...

Pond
A pond is an area filled with water, either natural or artificial, that is smaller than a lake. Defining them to be less than in area, less than deep, and with less than 30% emergent vegetation helps in distinguishing their ecology from that of lakes and wetlands.Clegg, J. (1986). Observer's Book of Pond Life. Frederick Warne, London Ponds can be created by a wide variety of natural processes (e.g. on floodplains as cutoff river channels, by glacial processes, by peatland formation, in coastal dune systems, by beavers), or they can simply be isolated depressions (such as a kettle hole, vernal pool, prairie pothole, or simply natural undulations in undrained land) filled by runoff, groundwater, or precipitation, or all three of these. They can be further divided into four zones: vegetation zone, open water, bottom mud and surface film. The size and depth of ponds often varies greatly with the time of year; many ponds are produced by spring flooding from rivers. Ponds may be ...
