Helen Beulah Thompson Gaige (November 24, 1890 – October 24, 1976) was an American herpetologist, curator of Reptiles and Amphibians for the Museum of Zoology at the University of Michigan, and a specialist in neotropical frogs. Gaige was born in Bad Axe, Michigan, and studied at the University of Michigan with Frank Nelson Blanchard, under professor Alexander Grant Ruthven. From 1910 until 1923 she was an assistant curator of reptiles and amphibians for the Museum of Zoology at the University of Michigan. In 1923 she became curator of amphibians. In 1928, she co-authored ''The Herpetology of Michigan'' with Ruthven. In 1937 she became editor in chief of the ichthyological and herpetological periodical ''Copeia'', and wrote extensively on Central American amphibians and reptiles. Her research chiefly concerned the geographical distribution, habitats, and life histories of amphibians. In 1917 she discovered the salamander genus ''Rhyacotriton','' which would later be divided ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Big Bend Slider
The Big Bend slider (''Trachemys gaigeae''), also called the Mexican Plateau slider, is a species of aquatic turtle in the family Emydidae. The species is endemic to the Southwestern United States and northern Mexico. Taxonomy The species ''Trachemys gaigeae'' was first described by professor of zoology at the University of Michigan, Dr. Norman Edouard Hartweg, in 1939, as a subspecies, ''Pseudemys scripta gaigeae''. Later, it was assigned to the genus ''Chrysemys'', then to the genus ''Trachemys''. Most recently, it was granted full species status, though many sources still refer to it by its various synonyms. The Nazas slider (''T. hartwegi'') of the Nazas River in northern Mexico was formerly considered a subspecies of ''T. gaigeae'', but was reclassified as a distinct species by the Turtle Taxonomy Working Group and the Reptile Database in 2021.

Sphenomorphus
The genus ''Sphenomorphus'' – vernacularly known as the common skinks – currently serves as a "wastebin taxon" for numerous skinks. While most or all species presently placed here are probably rather close relatives, the genus as presently delimited is likely to be not monophyletic and is in need of review. Some species in this genus have been moved to '' Pinoyscincus''. The namesake of the ''Sphenomorphus'' group of Lygosominae genera, most species would probably occupy a rather basal position therein.

Sphaerodactylus
''Sphaerodactylus'' is a genus of geckos from the Americas that are distinguished from other Gekkota by their small size, by their round, rather than vertical, eye pupils, and by each digit terminating in a single, round adhesive pad or scale, from which their name (''Sphaero'' = round, ''dactylus'' = finger) is derived. All species in this genus are rather small, but two species, '' S. ariasae'' and '' S. parthenopion'', are tiny, and – with a snout-vent length of about – the smallest reptiles in the world. Fossil record Fossil remains referred to ''Sphaerodactylus'' have been recovered from Dominican amber. Species The following 108 species are recognized as being valid. *'' Sphaerodactylus alphus'' - Guanaja large-scaled geckolet *''Sphaerodactylus altavelensis'' - Alto Velo least gecko, Alto Velo sphaero *''Sphaerodactylus argivus'' - Cayman least gecko *''Sphaerodactylus argus'' - ocellated gecko, ocellated sphaero, stippled sphaero *''Sphaerodactylus ariasae'' ...

Plestiodon Multivirgatus
''Plestiodon multivirgatus'', commonly known as the many-lined skink, the northern many-lined skink, or the variable skink, is a medium-sized species of lizard, a member of the North American skink genus ''Plestiodon'' in the family Scincidae. The species is native to the western United States. Taxonomy The taxonomy of this species is somewhat unclear, even amongst researchers. Most commonly, two subspecies are recognized: *''P. m. multivirgatus'' ( Hallowell, 1857) – northern many-lined skink *''P. m. epipleurotus'' (Cope, 1880) – variable skink The latter is sometimes treated as a separate species ''Plestiodon epipleurotus'' or ''Plestiodon gaigeae'' (Taylor, 1935), or given as the subspecies ''P. m. gaigeae''. These last two scientific names are in honor of American herpetologist Helen Beulah Thompson Gaige (1890–1976) of the University of Michigan. Beolens, Bo; Watkins, Michael; Grayson, Michael (2011).
