Phylogeny And Paleobiogeography Of Short-Tailed Shrews (Genus Blarina), Cheri A. Jones, Jerry R. Choate, Hugh H. Genoways
Phylogeny And Paleobiogeography Of Short-Tailed Shrews (Genus Blarina), Cheri A. Jones, Jerry R. Choate, Hugh H. Genoways
University of Nebraska State Museum: Mammalogy Papers
Dental measurements of Pleistocene and Holocene shrews of the genus Blarina were analyzed in a multivariate assessment of phylogeny and paleobiogeography of the genus. Blarina brevicauda, or an indistinguishable precursor, apparently was the ancestral form. Two semispecies, brevicauda and talpoides, are recognizable early in the fossil record; these two phena probably appeared as a result of increasing diversity'in the environment of the late Irvingtonian. Evidently, repeated fluctuations of climate and the subsequent changes in range have not been sufficient to cause the cessation of gene flow necessary to complete speciation.
A second species, B. carolinensis, appeared in …

Angularella Audubonensis Sp. N. (Dilepididae) And Other Cestodes Of Cliff Swallows In Colorado, Jeffrey D. Stamper, Gerald D. Schmidt
Harold W. Manter Laboratory of Parasitology: Faculty Publications
One hundred forty-five cliff swallows, Petrochelidon pyrrhonota, were examined for cestodes in two separate surveys in Weld County, Colorado. Seven species representing four genera were found. Angularella audubonensis sp. n. is differentiated by the small size of the rostellar hooks (8.4-13.5 μm) and the medial relationship of the cirrus pouch to the osmoregulatory canals. Other species collected were Angularella beema, Anonchotaenia globata, Mayhewia ababili, Vitta magniuncinata, Vitta parvirostris and Vitta riparia. Seven new hosts and geographic distribution records were established for Colorado, and six new records were determined for North America.

The Dynamics Of Animal Distribution: An Evolutionary/Ecological Model, Charles H. Smith
Faculty/Staff Personal Papers
Investigators have sometimes assumed that the factors underlying animal distribution are too complex to lend themselves to normative modelling. In this work, a model of environment and community interaction is constructed which lends itself to the latter kind of interpretation. It is posed that spatially-varying rates and magnitudes of availability of moisture at given locations act as stresses on the nature of community infrastructure, and secondarily on the rates at which new populations may become integrated into these. Populations are thereby viewed as tending to change range in common directions, though at overall rates remaining peculiar to each. This interpretation …

Aspects Of The Nesting Ecology Of Least Terns And Piping Plovers In Central Nebraska, Craig A. Faanes
Papers in Ornithology
Breeding habitat of the least tern is made up primarily of coastal beaches and inland river sandbars. Populations of the interior (Sterna antillarum athalassos) and east coast (S. a. antillarum) subspecies are now declining (Marshall et al. 1975, Duffy 1977, Jernigan et al. 1978) and the western subspecies (S. a. browni) is endangered (Wilbur 1974). Although coastal populations have received considerable attention (Wolk 1974, Atwood et al. 1977, Blodgett 1978), little research has been conducted on the interior race (Hardy 1957, Downing 1975).
The piping plover inhabits river sandbars and sand beaches and, like …

A Checklist Of Parasites Of California, Oregon, And Washington Marine And Estuarine Fishes, Milton S. Love, Mike Moser
Harold W. Manter Laboratory of Parasitology: Faculty Publications
This report is a summary of the published records of parasites found from the marine and estuarine fishes of California, Oregon, and Washington. Coverage has not been limited to the western United States, but rather includes parasite reports from throughout each fish's range. Included is a host-parasite list and parasite-host cross index.
We have produced this survey because we felt there was a need for a single source which would list all the parasites infecting marine and estuarine fish from California, Oregon, and Washington. Pertinent sources are scattered over a number of journals, covering many years. Workers find it time …

An Evaluation Of Small Rodents In Four Dismal Swamp Plant Communities, F. Elizabeth Breidling, Frank P. Day Jr., Robert K. Rose
Biological Sciences Faculty Publications
Diversity and density of small rodents in the Dismal Swamp are believed to be low. Reasons for this may be excessive predation, heavy interspecific pressure from large rodents, lack of suitable habitat, low food availability or flooding.
Rodent populations were evaluated using live-traps and pitfall traps in four different Dismal Swamp plant communities. Habitat was compared on the basis of phytomass studies previously reported. Flood levels were recorded during live-trapping sessions. Mast from trees was collected in modified mast collectors, and fed to Peromyscus leucopus in the laboratory.
Only two small rodent species were captured: Ochrotomys nuttalli and Peromyscus leucopus …

Comparison Of Old Field Succession On A Tallgrass Prairie And A Nebraska Sandhills Prairie, Mary Bomberger Brown, Shelly L. Shields, A. Tyrone Harrsion, Kathleen H. Keeler
School of Biological Sciences: Faculty Publications
Long held to be reasonably well understood, the process of ecological succession has recently come under attack. The predictability of successional changes has been doubted (Walker 1970), the mechanism of species replacement has been questioned (Connell and Slatyer 1977), and the reality of steady-state (climax) challenged (Botkin and Sobel 1975, Connell and Slatyer 1977, Connell 1978). In particular, several communities are presently recognized as having "cyclic succession" (Ricklefs 1973), in which the process is continually repeating. Such communities include heaths (Watt 1947), prairie pot-hole marshes (Vander Valk and Davis 1978), spruce-fir forests (Sprugel 1976, Sprugel and Bormann 1981), and intertidal …

Abundance And Distribution Of Large Mammals In The Upper Ogun Game Reserve, Oyo State, Nigeria, T. A. Afolayan, K. R. N. Milligan, S. O. Salami
International Journal for the Study of Animal Problems
Three different methods for estimating wild animal populations were used to assess the density of different species in a game reserve in the Sahel region of Nigeria. Hunting for bushmeat by local communities living around the reserve was identified as one of the threats to wildlife populations. Bushmeat was an essential resource for communities around the reserve.
Biological Control Of Aleutian Island Arctic Fox: A Preliminary Strategy, Edward W. West, Robert L. Rudd
Biological Control Of Aleutian Island Arctic Fox: A Preliminary Strategy, Edward W. West, Robert L. Rudd
International Journal for the Study of Animal Problems
The intentional introduction of exotic animals can generally be expected to yield unanticipated biological consequences. Single-purpose introductions frequently result in ecological catastrophe. Islands are particularly vulnerable to such assault. Arctic foxes [Alopex lagopus), released for fur farming on the Aleutian Islands, formerly devoid of land predators, have significantly altered nesting avifaunal diversity, abundance, and productivity. A program for restoring the historical distribution and abundance of critically affected bird species is described. In a long-term study, biological control methods are proposed to test the hypothesis that introduced sterile red foxes [Vulpes fulva), apparently, a competitively superior species, will markedly …
The North American Black Duck (Anas Rubriges): A Case Study Of 28 Years Of Failure In American Wildlife Management, John W. Grandy
The North American Black Duck (Anas Rubriges): A Case Study Of 28 Years Of Failure In American Wildlife Management, John W. Grandy
International Journal for the Study of Animal Problems
A scientific and technical analysis is presented of the factors that may have been responsible for an estimated 60% decline in the black duck (Anas rubripes) population since 1955. The analyses presented show that the U.S. Fish and Wildlife Service (FWS], the management agency responsible for waterfowl management in the United States, has recognized the population decline, that the FWS's own experts have consistently recognized that hunting is the most likely cause of the population decline and that hunting is the only mortality factor which wildlife managers can control in the practical sense. Using FWS information, the author …

Die Fauna der Mongolischen Volksrepublik war bis zu den 60er Jahren unseres Jahrhunderts fast unbekannt geblieben. Eine Ausnahme ist die Wirbeltierfauna, welche vor allem von russischen Zoologen gründlich erforscht und deren Resultate publiziert wurden. Dagegen hatten wir von den Wirbellosen nur spärliche Angaben in der Literatur, welche teils auf der Sammeltätigkeit russischer Forscher beruhen. Von ungarischer Seite war nur eine Expedition an der Jahrhundertwende (1898) von dem Grafen Eugen ZICHY durchgeführt worden, und während der kurzen Durchreise (3. bis 15. September) in der Mongolei hat sein Begleiter E. CSIKI, damaliger Kustos der Zoologischen Abteilung des Ungarischen Nationalmuseums, ein abwechslungsreiches zoologisches …

The nematode Heligmosomoides thomomyos sp. n. is described from the small intestine of Thomomys bulbivorus and T. bottae. This is the first report of Heligmosomoides from rodents of the family Geomyidae.
Nematodes of the genus Heligmosomoides Hall, 1916 occur most commonly in arvicolid rodents. Of the 26 known species of the genus, 11 have been recorded from Nearctic rodents (Rausch and Rausch, 1973). In North America, Heligmosomoides spp. have been recorded not only from voles, but also from cricetids and murids. Heligmosomoides spp. characteristically inhabit the small intestine or cecum of their host, where they usually are found …
