Inia is a genus of river dolphins from South America, containing one to four species.
A dunnart is a narrow-footed marsupial the size of a European mouse, of the genus Sminthopsis. Dunnarts have a largely insectivorous diet.
Microtus is a genus of voles found in North America, Europe and northern Asia. The genus name refers to the small ears of these animals. They are stout rodents with short ears, legs and tails. They eat green vegetation such as grasses and sedges in summer, and grains, seeds, root and bark at other times. The genus is also called "meadow voles".
Marmosops is a genus of Neotropical opossums of the family Didelphidae. The genus was originally treated as a subgenus from the genus Marmosa rather than having their own classification. This was changed in 1989 by Gardner and Crieghton, who officially separated the group and made them their own genus. The mix-up between to genera Marmosa and Marmosops was common due to the similar appearances including size and other external features. However, the two groups differ significantly in their integument and in the arrangement of their skull and dentition. The dentition is similar in morphology between the two groups, with the exception of the deciduous lower third premolar varying from one genus to the next. The similarity between the two continues to cause the genus Marmosops to be frequently misidentified due to the lack of knowledge regarding the species along with the overlooked traits that help separate them from other opossums. The Marmosops are also commonly confused with the genus Gracilinanus, but this is quickly ruled out by a large number of differing characteristics. These differences include the arrangement of their digits, caudal scales, and the central hair on the scales changing from a three hairs per follicle to many more. This causes the hair of the Gracilinanus to be thicker and has also found to be heavily pigmented. The last group commonly confused with Marmosops is known as the genus Thylamys. These animals have a contrasting dorsal body pelage and the taxa are actually quite different.
Diplomesodon is a genus of shrew that contains a single extant species, the piebald shrew (Diplomesodon pulchellus).
Maria Nazareth Ferreira da Silva is a zoologist from Manaus, Brazil.
Blanfordimys is a subgenus of voles in the family Microtus. It was formerly considered a distinct genus, but taxonomic studies group it within the Microtus radiation.
Chionomys is a genus of rodent in the family Cricetidae.
The juniper vole is a species of rodent in the family Cricetidae. It is found in Afghanistan, China, Pakistan and Tajikistan. It was formerly classified in the genus Neodon, but genetic evidence indicates that it is classified within the subgenus Blanfordimys in Microtus.
Tarsomys is a genus of rodent in the family Muridae found exclusively in Mindanao, Philippines.
Richard George Van Gelder was an American mammalogist who served as the Curator of Mammalogy for the American Museum of Natural History in New York for more than twenty-five years.
The Argentine fat-tailed mouse opossum was formerly considered a species of opossum in the family Didelphidae. It is found in the eastern foothills of the Andes in northern Argentina and southern Bolivia. Typically reach around 10-13 cm in body length, with a bushy tail adding another 12-15 cm. Its dorsal fur is gray brown to dark brown. Its ventral fur is gray-based except for the white to yellowish chest hairs. It has been distinguished from T. cinderella by its postorbital ridges. T. cinderella has well-developed postorbital ridges in both juveniles and adults that extend laterally behind the eye sockets. Only adults of T. sponsorius have fully developed postorbital ridges, and these do not extend laterally behind the eye sockets. While the American Society of Mammalogists maintains this as a distinct species, mitochondrial DNA sequence analysis does not support the population being distinct from T. cinderella.
Mondolfi's four-eyed opossum is a South American species of opossum found in Colombia and Venezuela, first described in 2006. It inhabits foothills of the Cordillera de Mérida and those on the eastern side of the Cordillera Oriental at elevations from 50 to 800 m. Populations in the two ranges may represent distinct subspecies. It is named after the Venezuelan biologist Edgardo Mondolfi. It has short woolly fur with a pale cream-colored venter as well as large ears pigmented on only the distal half. It is considered to be a junior synonym of the common four-eyed opossum by some sources, such as the Mammal Diversity Database.
The Society for Marine Mammalogy was founded in 1981 and is the largest international association of marine mammal scientists in the world.
Oliver Payne Pearson, or "Paynie" to many that knew him, was an American zoologist and ecologist. Over a very active 50-year career, he served as professor of zoology at UC Berkeley and curator of mammals at the Museum of Vertebrate Zoology. Pearson is best known for his work on the role of predation on vole demography and population cycles, and for his piercing contributions to the biology of South American mammals, but his earlier studies on reproductive and physiological ecology are highly regarded as well.
Don Ellis Wilson is an American zoologist. His main research field is mammalogy, especially the group of bats which he studied in 65 countries around the world.
Rodrigo A. Medellín is a Mexican ecologist and Senior Professor of Ecology at the Institute of Ecology, University of Mexico (UNAM). Known for his work in bat, jaguar, bighorn sheep and other species conservation, his research has always been designed and conducted to advice conservation policy and conservation decision-making processes in Mexico and 16 other countries for over 40 years.
Eugene Raymond Hall was an American mammalogist.
Neogale is a genus of carnivorous, highly active small mammals belonging to the Mustelidae family. Neogale contains four species: the Amazon weasel, the long and short-tailed weasels, and the American mink. Native to the Americas, members of the genus can be found as far north as Alaska and as far south as Argentina and Bolivia. Across this distribution, they thrive in a range of habitats, from the deep-freezes of the Alaskan and Canadian boreal forests to the arid desert southwest, and from the humid tropics of Central and South America to the windswept foothills of the Andes and northern Patagonia.
Massoia's lutrine opossum is a species of opossum native to South America.
