Josefa Celsa Señaris or Señaris (born 2 November 1965) is a Venezuelan herpetologist. She has published information about frogs and she has identified new genera and species. Señaris is the director of the La Salle Foundation's Natural History Museum (Spanish: ''Museo de historia natural La Salle - MhnLS'') in Caracas. ==Life== Señaris was born in 1965 and she obtained a degree in biology at the Central University of Venezuela and her doctorate in 2001 at the University of Santiago de Compostela in Spain. She is interested in the fauna of Venezuela, in particular the Guayana Region where table-top mountains called tepuis provide habitats for endemic plant and animal species: some amphibians are known only from a single tepuy. From a geological point of view, the tepuis have been isolated for approximately 120 million years,〔http://www.worldwildlife.org/ecoregions/nt0169 Tepui]. WWF.〕 and it has been suggested that the tepuy habitats are a "lost world" that could support relictual populations.〔''The Lost World'', Conan Doyle's novel featuring living dinosaurs, may have been inspired by these mountains.〕 However, Señaris's work suggests that in a zoological context tepuis are not as isolated as originally believed, and that some of their species are neoendemics rather than paleoendemics. For example, an endemic group of tree frogs, ''Tepuihyla'', have diverged after the tepuis were formed, that is, speciation followed colonization from the lowlands. Señaris became the director in 2004 of the La Salle Foundation's Natural History Museum (Spanish: ''Museo de historia natural La Salle - MhnLS'') in Caracas.〔 Señaris has erected two genera (including ''Tepuihyla'' mentioned above) and described several species new to science. In many cases Señaris collaborated with two other herpetologists, José Ayarzagüena and Stefan Gorzula.〔José Ayarzagüena Sanz (1952–2011) was a Spanish herpetologist who specialised in Venezuelan crocodiles as well as frogs. Stefan Jan Filip Gorzula is a British-trained American. 〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Josefa Celsa Señaris」の詳細全文を読む スポンサード リンク
