A mammal is a vertebrate animal of the class Mammalia. Mammals are characterized by the presence of milk-producing mammary glands for feeding their young,a neocortex region of the brain,fur or hair,and three middle ear bones. These characteristics distinguish them from reptiles and birds,from which their ancestors diverged in the Carboniferous Period over 300 million years ago. Around 6,400 extant species of mammals have been described and divided into 29 orders.
The culpeo,also known as culpeo zorro,Andean zorro,Andean fox,Paramo wolf,Andean wolf,and colpeo fox,is a species of South American fox. Regardless of the name,it is not a true fox,but more closely related to wolves and jackals. Its appearance resembles that of foxes due to convergent evolution.
In zoology,mammalogy is the study of mammals –a class of vertebrates with characteristics such as homeothermic metabolism,fur,four-chambered hearts,and complex nervous systems. Mammalogy has also been known as "mastology," "theriology," and "therology." The archive of number of mammals on earth is constantly growing,but is currently set at 6,495 different mammal species including recently extinct. There are 5,416 living mammals identified on earth and roughly 1,251 have been newly discovered since 2006. The major branches of mammalogy include natural history,taxonomy and systematics,anatomy and physiology,ethology,ecology,and management and control. The approximate salary of a mammalogist varies from $20,000 to $60,000 a year,depending on their experience. Mammalogists are typically involved in activities such as conducting research,managing personnel,and writing proposals.
Michael L. Rosenzweig is a professor of ecology and evolutionary biology at the University of Arizona. He developed and popularized the concept of Reconciliation ecology. He received his Ph.D in zoology at the University of Pennsylvania in 1966 and then held a number of academic positions around the United States.
The hoary bat is a species of bat in the vesper bat family,Vespertilionidae. It lives throughout most of North America.
The plains rat(Pseudomys australis),also known as the palyoora,plains mouse and eastern mouse,is a conilurine rodent native to arid and semi-arid Australia. Referred to as the pallyoora or yarlie by Indigenous groups,the plains rat was once widely distributed across central Australia,including north-west New South Wales and south-west Queensland;however,habitat degradation due to grazing,introduced predators and drought have contributed to its decline. Consequently,the plains rat has been listed as 'presumed extinct' in New South Wales and Victoria,'endangered' in the Northern Territory and Queensland and 'vulnerable' in Western Australia and South Australia. While recent research has indicated the presence of the plains rat in areas such as the Fowlers Gap and Strzelecki Desert regions of New South Wales and within the Diamantina National Park in Queensland,there are only five sub-populations currently recognised nationally,none of which coincide with recent discoveries of the plains rat. As the current population trend of the plains rat has been listed as 'declining' by the International Union for the Conservation of Nature (IUCN),the IUCN conservation status for the species is 'vulnerable'.
The sandy inland mouse is a species of rodent in the family Muridae. Also known as the Hermannsburg (Mission) false-mouse or Hermannsburg mouse,it is endemic to Australia and found widely yet sparsely through arid and semi-arid areas.
The plains viscacha rat,plains vizcacha rat,red viscacha rat,or red vizcacha rat is a species of rodent in the family Octodontidae native to Argentina. It is one of three species in the genus Tympanoctomys.
The delicate salt flat mouse is a sigmodontine rodent species in the family Cricetidae from South America. It is the only species in the genus Salinomys. Its habitat is scrublands bordering salt flats in the Monte Desert area of central western Argentina at elevations around 400 m. The closest relatives of the species are the chaco mice (Andalgalomys).
Bats are flying mammals of the order Chiroptera. With their forelimbs adapted as wings,they are the only mammals capable of true and sustained flight. Bats are more agile in flight than most birds,flying with their very long spread-out digits covered with a thin membrane or patagium. The smallest bat,and arguably the smallest extant mammal,is Kitti's hog-nosed bat,which is 29–34 millimetres in length,150 mm (6 in) across the wings and 2–2.6 g in mass. The largest bats are the flying foxes,with the giant golden-crowned flying fox reaching a weight of 1.6 kg and having a wingspan of 1.7 m.
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.
James Lloyd Patton,is an American evolutionary biologist and mammalogist. He is emeritus professor of integrative biology and curator of mammals at the Museum of Vertebrate Zoology,UC Berkeley and has made extensive contributions to the systematics and biogeography of several vertebrate taxa,especially small mammals.
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.
The western red bat or desert red bat is a species of microbat in the family Vespertilionidae. It is found in western North America and Central America.
Erna W. Mohr was a German zoologist who made contributions to ichthyology and mammalogy. Mohr was long associated with the Zoological Museum Hamburg,where she was successively head of the Fish Biology Department,Department of Higher Vertebrates,and Curator of the Vertebrate Department. She was a member of the Academy of Sciences Leopoldina and held an honorary doctorate from the University of Munich.
Aeorestes is a subgenus of Lasiurus commonly known as the hoary bats.
The South American hoary bat is a species of vesper bat found in South America.
David Christopher Dawber Happold,,in publications often D. C. D. Happold,is a British-Australian mammalogist. His main research interests are the small mammals of Africa and Australia.
Dasypterus is a subgenus of Lasiurus. Collectively,members of Lasiurus (Dasypterus) are referred to as the yellow bats.
