Eumops Perotis, Troy L. Best, W. Mark Kiser, Patricia W. Freeman

University of Nebraska State Museum: Mammalogy Papers

Eumops perotis is the largest bat in the United States. The greater mastiff bat resembles other North American free-tailed bats, but is distinguished from other molossids by its large size and lack of long guard hairs on the rump (Barbour and Davis, 1969). E. perotis has the thinnest dentary of any Eumops (Freeman, 1981a).In the United States, E. perotis can be separated from E. underwoodi by its larger size (forearm is 73-83 mm in E. perotis and 65-77 mm in E. underwoodi), darker color, and lack of long guard hairs on the rump. The ears are longer (36-47 mm …

A Recent Record Of Mountain Lion In Nebraska, Hugh H. Genoways, Patricia W. Freeman

University of Nebraska State Museum: Mammalogy Papers

On the morning of November 10, 1991, a deer hunter in the Pine Ridge area of extreme northwestern Nebraska shot a young female mountain lion (Gertzen, 1991, Omaha World-Herald, November 15, Sunrise ed. p. 17sf; Henion, 1991, Omaha World-Herald, November 15, Metro ed. p. 17). Although mountain lions (Felis concolor) were part of the original mammalian fauna of Nebraska (Jones, 1949, J. Mammal. 30: 313; 1962, Bull Univ. Nebraska State Mus. 4: 87-100; 1964, Univ. Kansas Publ., Mus. Nat. Hist. 16: 1-356), the species has been considered to be extirpated from the state. The most recent record that …

Mammals Of The Mixedwood Plains Ecozone, Andrew Smith, Donald A. Smith

University of Nebraska State Museum: Mammalogy Papers

Ontario and Quebec were totally covered with ice during the last glaciation. Deglaciation was followed by gradual post-glacial repopulation of these two provinces (and others) by mammals from source areas in the United States. Thus most range expansions were from south to north east of the Great Lakes.

The mammalian fauna of the Mixedwood Plains Ecozone has been steadily changing since deglaciation about 10 000 years ago. During this period a succession of species assemblages has moved through this ecozone as the climate warmed. Several of the larger mammal species known from this area became extinct during this period of …

Notes On Bats From Montserrat (Lesser Antilles) With Comments Concerning The Effects Of Hurricane Hugo, Scott C. Pedersen, Hugh H. Genoways, Patricia W. Freeman

University of Nebraska State Museum: Mammalogy Papers

From August 1993 to August 1994, bats were surveyed on Montserrat, Lesser Antilles. Four years after this small volcanic island was struck by Hurricane Hugo (1989), there remains a 20-fold decrease in bat populations as compared to levels before Hugo. After the hurricane, composition of the community shifted from smaller frugivorous species to one of more omnivorous and larger frugivorous species. With the addition of a new record for Sturnira thomasi, voucher specimens from Montserrat exist for ten species of Chiroptera: Noctilio leporinus, Monophyllus plethodon, Sturnira tkomasi, Chiroderma improvisum, Artibeus jamaicensis, Ardops nichollsi, Brachyphylla cavernarum, Natalus stramineus, Tadarida brasiliensis …

Molecular Systematics Of The Fruit Bat, Artibeus Jamaicensis: Origin Of An Unusual Island Population, Dorothy E. Pumo, Iksoo Kim, James Remsen, Carleton J. Phillips, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

DNA sequences from mitochondrial tRNA genes, the light strand replication site, and a region of the 12s rRNA gene were used to test the hypothesis that the unusual Antillean island subspecies, Artibeus jamaicensis schwartzi, was derived from a South American origin. Parsimony and bootstraping analyses allied the mitochondrial genome in these bats with mitochondrial DNA (mtDNA) isolated from Artibeus planirostris living in French Guiana rather than with mtDNA isolated from Artibeus jamaicensis from the Antilles or Mexico. Although the tRNA sequences differed slightly, the 12s rRNA sequences were identical in mtDNA isolated from A. j. schwartzi on St. Vincent …

Obituary: J. Knox Jones, Jr., 1929-1992, James S. Findley, Clyde Jones, Hugh H. Genoways, Elmer C. Birney, Robert J. Baker

University of Nebraska State Museum: Mammalogy Papers

J. Knox Jones, Jr., was born in Lincoln, Nebraska, March 16, 1929, the eldest of the three sons of Virginia Bowen Jones and James Knox Jones. Knox passed away at his home in Lubbock, Texas, on November 15, 1992, after a two-year battle with cancer.

A New Species Of The Genus Rhogeessa, With Comments On Geographic Distribution And Speciation In The Genus, Hugh H. Genoways, Robert J. Baker

University of Nebraska State Museum: Mammalogy Papers

A new species of Rhogeessa is described from southern Suriname. The new species is characterized by a karyotype that possesses a diploid number of 52 and a fundamental number of 52 and by its relatively large overall size compared to other South American Rhogeessa. Tenspecies are now recognized within the genus. Seven of these species, including the one described herein, are members of R. tumida complex. Two of these species--R. io and R. minutilla--also occur in South America and the remaining four species are confined to Mexico and Central America.
