Phrynobatrachus Graueri

	Phrynobatrachus Graueri ''Phrynobatrachus graueri'' is a species of frog in the family Phrynobatrachidae. It is found in eastern Democratic Republic of the Congo, Rwanda, Uganda, and western Kenya. The specific name ''graueri'' honours Rudolf Grauer, Austrian explorer and zoologist who collected the holotype. Common names Rugege river frog and Grauer's puddle frog have been coined for it. Description Adult males can grow to and adult females in snout–vent length. The snout is short. The tympanum is distinct and about one-half of the eye width. The fingers and toes have distinct discs. The toes are slightly webbed. The dorsum is dark olive. A darker band runs from the nostril to the forearm. There might be a narrow or wide vertebral stripe. A pair of light lines are flanking the vent. Males have black throat. The base of the hind limb is often yellow. Habitat and conservation ''Phrynobatrachus graueri'' occurs in montane forest interior and edges at elevations greater than , often in association w ...

	Fritz Nieden Fritz Nieden (1883 – 1942) was a German zoologist who specialized in African herpetology. He worked as a zoologist at the ''Museum für Naturkunde'' in Berlin. His name is associated with Nieden's dwarf skink, '' Panaspis megalurus''. In 1911 he was the first to describe '' Callulina kreffti'', a species of frog, which until 2004 was the only known species of the genus ''Callulina''. The Sagala caecilian, ''Boulengerula niedeni'', is named after him.

picture info	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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Amphibians Described In 1911 Amphibians are four-limbed and ectothermic vertebrates of the class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within 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 recent decades there has been a dramatic decline ...
