Bats Of Guadeloupe, Robert J. Baker, Hugh H. Genoways, John C. Patton May 1978

Bats Of Guadeloupe, Robert J. Baker, Hugh H. Genoways, John C. Patton

University of Nebraska State Museum: Mammalogy Papers

The bat fauna of the Lesser Antillean chain is of considerable interest because it is composed of a depauperate extension of the South American fauna, species that have a widespread distribution in the Antilles, and a few species that are endemic to the Lesser Antilles (Baker and Genoways, 1978). Relative to bat speciation and diversity, Guadeloupe is probably the most important island of the Antillean chain.

This report is concerned with the natural history and systematics of the 11 chiropteran species known from Guadeloupe, three of which are endemic. Comments concerning systematic relationships are based on specimens that we collected …


Bats From Southern Haiti, David Klingener, Hugh H. Genoways, Robert J. Baker Mar 1978

Bats From Southern Haiti, David Klingener, Hugh H. Genoways, Robert J. Baker

University of Nebraska State Museum: Mammalogy Papers

A collection of 450 specimens of bats from the Departement du Sud, Haiti, is described. Fifteen of the 17 species previously recorded from Hispaniola are represented, and Noctilio leporinus is reported from Haiti for the first time. Reproductive information for the months of January, May, June, August, and December is presented. Macrotus waterhousii is seasonally monoestrous, as on the mainland. The two species of stenodennines, Artibeus jamaicensis and Phyllops hailiensis, do not show bimodal seasonal polyestry as do stenodermines in Central America. Monophyllus redmani and the phyllonycterines may be seasonally monoestrous. Differences in reproductive biology between Haitian bats and …

Relating Wolf Scat Content To Prey Consumed, Theodore J. Floyd, L. David Mech, Peter A. Jordan Jan 1978

Relating Wolf Scat Content To Prey Consumed, Theodore J. Floyd, L. David Mech, Peter A. Jordan

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

In 9 trials, captive wolves (Canis lupus) were fed prey varying in size from snowshoe (Lepus americanus) to adult deer (Odocoileus virginianus), and the resulting scats were counted. collectible scats were distinguished from liquid, noncollectible stools. In collectible scats, the small prey occurred in greater proportion relative to the prey's weight, and in lesser proportion to the prey's numbers, than did the remains of larger prey. A regression equation with an excellent the data (r2 = 0.97) was derived to estimate the weight of prey eaten per collectible scat for With this information …


Zoogeography Of Antillean Bats, Robert J. Baker, Hugh H. Genoways Jan 1978

Zoogeography Of Antillean Bats, Robert J. Baker, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Analysis of the bat fauna of the Antillean Islands suggest that the most probable source of invasion of the islands by bats is by overwater dispersal. The bat fauna of ·the Greater Antilles is unique, a percentage of endemism on each island being over 50 percent except for the Virgin Islands which has 33 percent endemics.

The richest bat fauna in the Antilles is on Cuba (32 species) followed by Jamaica (23 species) then Hispaniola (17 species) and Puerto Rico (16 species). The number of species found on Cuba is probably the result of the island's proximity to Central and …


Productivity, Mortality, And Population Trends Of Wolves In Northeastern Minnesota, L. David Mech Nov 1977

Productivity, Mortality, And Population Trends Of Wolves In Northeastern Minnesota, L. David Mech

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Population parameters, mortality causes, and mechanisms of a population decline were studied in wolves (Canis lupus lycaon) from 1968 to 1976 in the Superior National Forest. The main method was aerial radio-tracking of 129 wolves and their packmates. Due to a decline in white-tailed deer (Odocoileus virginianus), the wolf population decreased during most of the study. Average annual productivity varied from 1.5 to 3.3 pups per litter, and annual mortality rates from 7 to 65 percent. Malnutrition and intraspecific strife accounted equally for 58 percent of the mortality; human causes accounted for the remainder. As wolf …


Wolf-Pack Buffer Zones As Prey Reservoirs, L. David Mech Oct 1977

Wolf-Pack Buffer Zones As Prey Reservoirs, L. David Mech

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Abstract. In a declining herd, surviving deer inhabited overlapping edges of wolf- pack territories. There, wolves hunted little until desperate, in order to avoid fatal encounters with neighbors. Such encounters reduce wolf numbers and predation pressure and apparently allow surviving deer along territory edges to repopulate the area through dispersal of their prime, less vulnerable offspring into territory cores.


Comparison Of Coyote And Coyote × Dog Hybrid Food Habits In Southeastern Nebraska, Brian R. Mahan Sep 1977

Comparison Of Coyote And Coyote × Dog Hybrid Food Habits In Southeastern Nebraska, Brian R. Mahan

University of Nebraska State Museum: Mammalogy Papers

The recent taxonomic study by Mahan et al. (1978) documented the occurrence of coyote (Canis latrans) x dog (c. familiaris) hybrids in Nebraska. This study, and those by Freeman (1976) in Oklahoma and Gipson et al. (1974) in Arkansas show coyote x dog hybrids, though not abundant, to be numerous in some areas. The purpose of the present study was to compare the stomach contents of coyote x dog hybrids collected by Mahan et al. (1978) from southeastern Nebraska with those of contemporary coyotes.

Stomachs of 12 coyote x dog hybrids and 16 coyotes collected November 1975 …

A New Species Of Chiroderma From Guadeloupe, West Indies (Chiroptera: Phyllostomidae), Robert J. Baker, Hugh H. Genoways Apr 1976

A New Species Of Chiroderma From Guadeloupe, West Indies (Chiroptera: Phyllostomidae), Robert J. Baker, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

During the course of a study of the bat faunas of the Caribbean islands we obtained a specimen of Chiroderma from the island of Guadeloupe in the Lesser Antilles. The nearest known populations of this genus occur on Tobago and Trinidad (C. villosum and C. trinitatum). approximately 550 kilometers to the south. This specimen represents a distinct new species that appears to be most closely related to C. doriae and C. villosum. This new species is named and described.

A New Species Of Eptesicus From Guadeloupe, Lesser Antilles (Chiroptera: Vespertilionidae), Hugh H. Genoways, Robert J. Baker Jul 1975

A New Species Of Eptesicus From Guadeloupe, Lesser Antilles (Chiroptera: Vespertilionidae), Hugh H. Genoways, Robert J. Baker

University of Nebraska State Museum: Mammalogy Papers

In the course of field studies on bats of the Antillean region, three specimens of the genus Eptesicus were obtained on the island of Guadeloupe in the Lesser Antilles. The nearest known populations of this genus are on Puerto Rico 500 kilometers to the west (E. fuscus wetmorei), on the northern coast of South America 850 kilometers to the southwest (E. fuscus miradorensis), and on Tobago 550 kilometers to the south (E. brasiliensis melanopterus). Study of the specimens from Guadeloupe reveals that they represent a distinct species that is most closely related to Eptesicus …


A New Subspecies Of Geomys Bursarius (Mammalia: Geomyidae) From Texas And New Mexico, Robert J. Baker, Hugh H. Genoways Apr 1975

A New Subspecies Of Geomys Bursarius (Mammalia: Geomyidae) From Texas And New Mexico, Robert J. Baker, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

As part of a study of the systematics and ecology of pocket gophers occurring on the high plains of Texas and eastern New Mexico, numerous populations of the plains pocket gopher, Geomys bursarius, were examined karyotypically. Four chromosomal races were described from this area by Baker et al. (1973). Additional studies lead us to believe that two of these races represent an undescribed subspecies of the plains pocket gopher. In addition to karyological evidence, specimens of this subspecies are morphologically distinct from those of all contiguous populations of Geomys bursarius major, the race to which they previously were assigned. …

Mammals Of The Guadalupe Mountains National Park, Texas, Hugh H. Genoways, Robert J. Baker, John E. Cornely

University of Nebraska State Museum: Mammalogy Papers

Our survey began in late May 1973 and continued through August 1975. The objectives of our study, which was supported by the National Park Service, were to survey the mammals occurring in the Guadalupe Mountains National Park, Texas, and to correlate their distribution with major plant associations. This inventory of the natural resources of the park is preliminary to the development of any serious management program. Therefore, we present the following accounts to serve as baseline data for future mammalian work in the park and development of the master plan for the park.

Editors' Note To Biological Investigations In The Guadalupe Mountains National Park, Texas., Hugh H. Genoways, Robert J. Baker

University of Nebraska State Museum: Mammalogy Papers

The Guadalupe Mountains National Park, which is located in TransPecos Texas between Carlsbad, New Mexico, and EI Paso, Texas, is one of the newest national parks being formed by the Congress in 1967. The Guadalupe Mountains and the associated Chihuahuan Desert included in the park represent a unique biological area in which a fragile biological equilibrium exists between the fauna and flora of the Chihuahuan Desert of the lowlands and the Rocky Mountains of the high elevations. The preservation of this area will depend upon sound management decisions. This volume is the result of a symposium held at The Museum …

Raising Wood Ducks, Richard L. Nelson Jan 1975

Raising Wood Ducks, Richard L. Nelson

Nebraska Game and Parks Commission: Publications

Numbered among Nature's most colorful creatures, wood ducks willingly accept a helping hand from man in establishing new homes. These birds adapt well to suitable habitat, and you can play an important part in bringing the wood duck to locations where they do not now nest. For groups or individuals who are willing to expend the effort necessary to undertake a wood duck restoration project anti see it to completion, it is an exceptional gift from today's generation to those of decades and centuries to come. Many areas in Nebraska provide suitable wood duck habitat, but do not have a …


Karyotype Of Geomys Pinetis (Mammalia: Geomyidae), With A Discussion Of The Chromosomal Relationships Within The Genus, S. L. Williams, Hugh H. Genoways Jan 1975

Karyotype Of Geomys Pinetis (Mammalia: Geomyidae), With A Discussion Of The Chromosomal Relationships Within The Genus, S. L. Williams, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Summary. Four of the five subspecies of Geomys pinetis were karyotyped. All specimens examined had a diploid number of 42 and a fundamental number of 80. This karyotype was compared with the described karyotypes of other species of Geomys and was considered to be derived from an ancestoral form having a karyotype of about 70 acrocentric elements.


Taxonomy And Zoogeography Of Lemmus Spp. (Rodentia: Arvicolinae), With Notes On Laboratory-Reared Lemmings, Robert L. Rausch, Virginia R. Rausch Jan 1975

Taxonomy And Zoogeography Of Lemmus Spp. (Rodentia: Arvicolinae), With Notes On Laboratory-Reared Lemmings, Robert L. Rausch, Virginia R. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Lemmings of the genus Lemmus Link, 1795, have long attracted interest because of the high numerical densities attained at intervals by their populations. In earlier times, in northern Europe, such events seemed so remarkable as to be explained by some as a consequence of the animals' having fallen from the sky (HaGSTROM 1749). During the last 25 years, lemmings have been the object of intensive ecological investigation in Eurasia and North America, although there has been no consensus concerning their taxonomic relationships. In 1959, a colony of brown lemmings from arctic Alaska was established in our laboratory, primarily to provide …

Bats Of Margarita Island, Venezuela, With Zoogeographic Comments, James Dale Smith, Hugh H. Genoways Aug 1974

Bats Of Margarita Island, Venezuela, With Zoogeographic Comments, James Dale Smith, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Sixteen species of bats are reported from Margarita Island, Nueva Esparta, Venezuela. These include two species of emballonurids, one noctilionid, two mormoopids, nine phyllostomatids, one vespertilionid, and one molossid. Accounts including natural history and taxonomic comments are given for each species. The chiropteran fauna of Margarita Island is compared with the bat faunas of the adjacent Venezuelan mainland and islands off the northern coast of South America, including Trinidad and other Antillean islands. It is concluded that the chiropteran fauna of Margarita Island represents an attenuated mainland fauna.
