Kassina Cochranae
''Kassina cochranae'', sometimes known as the Cochran's running frog, is a species of frog in the family Hyperoliidae. It is found in southern Guinea, Liberia, Sierra Leone, western Ivory Coast (the Mount Nimba area, possibly wider), and at least tentatively, southern Ghana. '' Kassina arboricola'' was for a period treated as a subspecies ''Kassina cochranae arboricola'', but it is now considered a valid species. Etymology The specific name ''cochranae'' honours Doris Mable Cochran, an American herpetologist. Description ''Kassina cochranae'' are medium-sized, sturdy frogs. The legs and arms are short. There are 35–77 large spots on flanks and dorsum. The belly is white to brown and sometimes has scattered, small punctuations (but never with large spots). There are zero to two occipital spots. Males typically have dark throat that sometimes has black spots. Habitat and conservation ''Kassina cochranae'' is an arboreal, forest-dwelling species, including secondary forests. The ...

Arthur Loveridge
Arthur Loveridge (28 May 1891 – 16 February 1980) was a British biologist and herpetologist who wrote about animals in East Africa, particularly Tanzania, and New Guinea. He gave scientific names to several gecko species in the region. Arthur Loveridge was born in Penarth, and was interested in natural history from childhood. He gained experience with the National Museum of Wales and Manchester Museum before becoming the curator of the Nairobi Museum (now the National Museum of Kenya) in 1914. During WW1, he joined the East African Mounted Rifles, later returning to the museum to build up the collections. He then became an assistant game warden in Tanganyika. In 1924, he joined the Museum of Comparative Zoology in the grounds of Harvard University in Cambridge, Massachusetts, where he was the curator of herpetology. He returned to East Africa on several field trips and wrote many scientific papers before retiring from Harvard in 1957. He married Mary Victoria Sloan in 192 ...

Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphibians Described In 1941
Amphibians are tetrapod, four-limbed and ectothermic vertebrates of the Class (biology), class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial animal, terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kassina
''Kassina'' is a genus of hyperoliid frogs, commonly referred to as running frogs or kassinas. They are found throughout sub-Saharan Africa. They are characterized by preferring a distinctive "walking" with the back legs instead of the more traditional frog-hopping. Species The following species are recognized in the genus ''Kassina'': In captivity ''K. maculata'' is frequently exported from Tanzania for the exotic pet A pet, or companion animal, is an animal kept primarily for a person's company or entertainment rather than as a working animal, livestock, or a laboratory animal. Popular pets are often considered to have attractive appearances, intelligence, ... trade. They require more horizontal space than vertical, being a terrestrial species. Their captive environment should include a substrate that accommodates burrowing, and provides high humidity. ''K. maculata'' will readily eat crickets and small mealworms, although insects should be dusted with a vitamin sup ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat Loss
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

Savanna
A savanna or savannah is a mixed woodland-grassland (i.e. grassy woodland) ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses. According to '' Britannica'', there exists four savanna forms; ''savanna woodland'' where trees and shrubs form a light canopy, ''tree savanna'' with scattered trees and shrubs, ''shrub savanna'' with distributed shrubs, and ''grass savanna'' where trees and shrubs are mostly nonexistent.Smith, Jeremy M.B.. "savanna". Encyclopedia Britannica, 5 Sep. 2016, https://www.britannica.com/science/savanna/Environment. Accessed 17 September 2022. Savannas maintain an open canopy despite a high tree density. It is often believed that savannas feature widely spaced, scattered trees. However, in many savannas, tree densities are higher and trees are more regularly spaced than in for ...

Arboreal Locomotion
Arboreal locomotion is the 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 narrow branches, mov ...

Dorsum (anatomy)
Standard anatomical terms of location are used to unambiguously describe the anatomy of animals, including humans. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and anatomical axes. The meaning of terms that are used can change depending on whether an organism is bipedal or quadrupedal. Additionally, for some animals such as invertebrates, some terms may not have any meaning at all; for example, an animal that is radially symmetrical will have no anterior surface, but can still have a description that a part is close to the middle ("proximal") or further from the middle ("distal"). International organisations have determined vocabularies that are often used as standard vocabularies for subdisciplines of anatom ...

Doris Mable Cochran
Doris Mable Cochran (May 18, 1898 – May 22, 1968) was an American Herpetology, herpetologist and custodian of the American Natural Collection at the Smithsonian Institution in Washington, D.C., for many years. Life Born in North Girard, Pennsylvania, she grew up in Washington, D.C., after her father transferred there for a government job. While an undergraduate student at George Washington University (A.B. 1920, M.S. 1921), she worked for the United States Department of War, War Department and became Aide in the Division of Herpetology at the United States National Museum. Although the museum was under the curatorship of Leonhard Stejneger, Cochran was responsible for the administration of the herpetological collections. In 1927 she became Assistant Curator, and in 1942, Associate Curator just prior to Stejneger's death. She earned a Ph.D. at the University of Maryland, College Park, University of Maryland in 1933 with a thesis on Callinectes sapidus, blue crab musculature. ...

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet or species epithet) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the specific the proper term for ...

Kassina Arboricola
''Kassina arboricola'', sometimes known as the Ivory Coast running frog, is a species of frog in the family Hyperoliidae. It is found in southwestern Ghana and westward to south-central Ivory Coast. It occurs in secondary forests and forest edges, and to very limited extent, degraded former forest (farm bush). Breeding takes place in both temporary and permanent bodies of water, although it favours large, well-vegetated pools. It is probably negatively impacted by severe deforestation caused by agricultural expansion Agricultural expansion describes the growth of agricultural land (arable land, pastures, etc.) especially in the 20th and 21st centuries. The agricultural expansion is often explained as a direct consequence of the global increase in food and ene ..., logging, and growing human settlements.
