Morphological Variation, Karyology, And Systematic Relationships Of Heteromys Gaumeri (Rodentia: Heteromyidae), Mark D. Engstrom, Hugh H. Genoways, Priscilla K. Tucker Jan 1987

Morphological Variation, Karyology, And Systematic Relationships Of Heteromys Gaumeri (Rodentia: Heteromyidae), Mark D. Engstrom, Hugh H. Genoways, Priscilla K. Tucker

University of Nebraska State Museum: Mammalogy Papers

Morphological variation was assessed within and among populations of Heteromys gaumeri using univariate and multivariate statistical analyses of external and cranial measurements. Although patterns and amount of nongeographic variation in H. gaumeri were similar to other heteromyines, geographic variation was relatively conservative. Mean values of most characters were statistically homogeneous among localities and spatially unpatterned. Consequently, no association was found between levels of within- and among-sample variation for individual characters (the "Kluge-Kerfoot phenomenon"). Populations of H. gaumeri were chromosomally monomorphic. The lack of morphological and chromosomal variation in H. gaumeri contrasts sharply with patterns in other heteromyines. Heteromys gaumeri is …

Revised Checklist Of North American Mammals North Of Mexico, 1986, J. Knox Jones Jr., Dilford C. Carter, Hugh H. Genoways, Robert S. Hoffmann, Dale W. Rice, Clyde Jones Dec 1986

Revised Checklist Of North American Mammals North Of Mexico, 1986, J. Knox Jones Jr., Dilford C. Carter, Hugh H. Genoways, Robert S. Hoffmann, Dale W. Rice, Clyde Jones

University of Nebraska State Museum: Mammalogy Papers

As in previous lists, orders, families, and genera are listed in conventional phylogenetic sequence mostly following Hall (1981) but, in a departure from previous lists, species are entered alphabetically within each genus. This will facilitate use of the checklist by those unfamiliar with intrageneric taxonomy. Some assemblages are not well enough understood to create a meaningful hierarchy at the specific level.


Eulimdana Rauschorum N. Sp., A Filarioid Nematode (Lemdaninae) From Larus Dominicanus In Antarctica, With Comments On Evolution And Biogeography, Eric P. Hoberg Oct 1986

Eulimdana Rauschorum N. Sp., A Filarioid Nematode (Lemdaninae) From Larus Dominicanus In Antarctica, With Comments On Evolution And Biogeography, Eric P. Hoberg

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Eulimdana rauschorum n. sp. is described from southern black-backed gulls, Larus dominicanus Lichtenstein in Antarctica. The species is most similar to Eulimdana lari (Yamaguti, 1935) from Charadriiformes in the Holarctic. Males have spicules equal in length that are asymmetric in structure distally. There are 4-5 and 3-5 caudal papillae in rows to the right and left of the anus, and two small genital papillae at the posterolateral margin of the anus. Females have a variable number of prominent caudal papillae and large microfilariae (365 μm in length). The morphological similarities and host distribution of E. rauschorum and E. lari suggest …


Mortality Of White-Tailed Deer In Northeastern Minnesota, Michael E. Nelson, L. David Mech Oct 1986

Mortality Of White-Tailed Deer In Northeastern Minnesota, Michael E. Nelson, L. David Mech

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

Abstract: Two hundred nine white-tailed deer (Odocoileus virginianus) were radiotracked in the central Superior National Forest, Minnesota, from 1973 through winter 1983-84; 85 deaths were recorded. Annual survival was 0.31 for fawns (<1.0 years old), 0.80 for yearling (1.0-2.0 years old) females, 0.41 for yearling males, 0.79 for adult (≥2.0 years old) females, and 0.47 for adult males. Monthly survival rates were high from May through December (0.94-1.00), except for yearling (0.60) and adult (0.69) bucks during the November hunting season. Most mortality occurred from January through April when gray wolf (Canis lupus) predation was an important mortality source for all cohorts. Yearlings males were most vulnerable to hunting and adult males to wolf predation.


Relationship Between Snow Depth And Gray Wolf Predation On White-Tailed Deer, Michael E. Nelson, L. David Mech Jul 1986

Relationship Between Snow Depth And Gray Wolf Predation On White-Tailed Deer, Michael E. Nelson, L. David Mech

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

Abstract: Survival of 203 yearling and adult white-tailed deer (Odocoileus virginianus) was monitored for 23,441 deer days from January through April 1975-85 in northeastern Minnesota. Gray wolf (Canis lupus)predation was the primary mortality cause, and from year to year during this period, the mean predation rate ranged from 0.00 to 0.29. The sum of weekly snow depths/month explained 51% of the variation in annual wolf predation rate, with the highest predation during the deepest snow.

Bird Use Of Lakes In The Claremont-Upland Area, Valerie Banschbach

Pomona Senior Theses

I studied water bird use of two lakes in the Claremont-Upland area to determine what physical, chemical, and biological aspects of these lakes provide suitable water bird habitat and food resources. I censused the Bernard Field Station Lake in Claremont and a gravel pit freshwater area in Upland from 10/85 to 3/86 for water bird use. I also mapped these sites, noted their water surface area and water depth changes, monitored their water chemistry, and censused their vegetation. The results of this work showed more total water birds per hour of observation time, and more birds per hour of observation …

Evolution And Historical Biogeography Of A Parasite-Host Assemblage: Alcataenia Spp. (Cyclophyllidea: Dilepididae) In Alcidae (Charadriiformes), Eric P. Hoberg Jan 1986

Evolution And Historical Biogeography Of A Parasite-Host Assemblage: Alcataenia Spp. (Cyclophyllidea: Dilepididae) In Alcidae (Charadriiformes), Eric P. Hoberg

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The methodology of phylogenetic systematics was used to develop hypotheses for the evolution of eight species of Alcataenia, a group of host-specific cestodes of the Alcidae and, to a lesser extent, the Laridae (Charadriiformes). Concurrently, aspects of the early biogeography of alcids were reevaluated making it possible to study the historical and distributional relationships of parasites and hosts. The most parsimonious hypothesis for the phylogeny of Alcataenia suggested that sequential colonization or host switching with limited coevolution (coaccommodation) by parasites best explained the distributional patterns exhibited by Alcataenia spp. Morphological evolution of specific species of Alcataenia accompanied host switching, …


Reproductive Strategies Of Meadow Voles, Hispid Cotton Rats, And Eastern Harvest Mice In Virginia, Robert K. Rose Jan 1986

Reproductive Strategies Of Meadow Voles, Hispid Cotton Rats, And Eastern Harvest Mice In Virginia, Robert K. Rose

Biological Sciences Faculty Publications

Patterns of reproduction in small mammals in Virginia were examined by autopsying samples of meadow voles (Microtus pennsylvanicus) collected for 23 months near Charlottesville, of hispid cotton rats (Sigmodon hispidus) collected for 14 months in Portsmouth, and by evaluating live-caught eastern harvest mice (Reithrodontomys humulis) trapped for 15 months in Suffolk and for 12 months in Chesapeake. The meadow vole, a microtine rodent with a north temperate and sub-arctic distribution throughout North America, suspended breeding during the winter of peak density but not of declining density. High metabolic rates and other adaptations for winter …

Vegetation Patterns In Relation To Topography And Edaphic Variation Nebraska Sandhills Prairie, P. W. Barnes, A. T. Harrison, S. P. Heinisch Dec 1984

Vegetation Patterns In Relation To Topography And Edaphic Variation Nebraska Sandhills Prairie, P. W. Barnes, A. T. Harrison, S. P. Heinisch

School of Biological Sciences: Faculty Publications

Detailed studies on soil texture and moisture retention indicate a close association between edaphic features and the distribution and composition of plant communities along topographic gradients at Arapaho Prairie, a typical, semi-arid Nebraska Sandhills prairie. The vegetation characteristics of three major habitat types (ridge, slope, and valley) and several minor subtypes (swale, stable ridge, and eroding ridge) are recognized and quantitatively described. Texture analysis indicates that the soils of dune slopes and ridges are largely azonal and are very coarse with substantially lower fine fractions (silt-clay ~ 13-15%) than soils of the more lowland swale and valley sites where surfact …

Results Of The Alcoa Foundation-Suriname Expeditions. Ix. Bats Of The Genus Tonatia (Mammalia: Chiroptera) In Suriname, Hugh H. Genoways, Stephen L. Williams Jul 1984

Results Of The Alcoa Foundation-Suriname Expeditions. Ix. Bats Of The Genus Tonatia (Mammalia: Chiroptera) In Suriname, Hugh H. Genoways, Stephen L. Williams

University of Nebraska State Museum: Mammalogy Papers

Five species of Tonatia (bidens, brasilense, carrikeri, schulzi, and silvicola) are known to occur in Suriname. Tonatia bidens and silvicola are the largest in overall size (forearm length over 50 mm and greatest length of skull over 27.0 mm). However, T. bidens has a broader postorbital region (5.0 mm or more) and narrower mastoid region (less than 13.0 mm). The lower incisors of T. bidens are also noticeably broader than those of T. silvicola. These two species were found throughout most of the forested areas of Suriname. T. bidens displayed no secondary sexual …
