Experimental Infections Of Muskoxen (Ovibos Moschatus) And Domestic Sheep With Umingmakstrongylus Pallikuukensis (Nematoda: Protostrongylidae): Parasite Development, Population Structure, And Pathology, Susan J. Kutz, Eric P. Hoberg, Lydden Polley Jan 1999

Experimental Infections Of Muskoxen (Ovibos Moschatus) And Domestic Sheep With Umingmakstrongylus Pallikuukensis (Nematoda: Protostrongylidae): Parasite Development, Population Structure, And Pathology, Susan J. Kutz, Eric P. Hoberg, Lydden Polley

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Three captive muskoxen (Ovibos moschatus) were successfully infected with third-stage larvae of Umingmakstrongylus pallikuukensis digested or emerged from the slugs Deroceras reticulatum and D. laeve, for the first time completing the life cycle of this parasite under experimental conditions. The course of parasite development and patency was followed for 26 months post infection (p.i.) using fecal examinations and radiography. The prepatent periods in two of the muskoxen were 91 and 95 days and the patent period in one extended for 23 months. Larval production peaked 13–14 months p.i. On postmortem of two of the muskoxen at months …

Regurgitative Food Transfer Among Wild Wolves, L. David Mech, Paul C. Wolf, Jane M. Packard Jan 1999

Regurgitative Food Transfer Among Wild Wolves, L. David Mech, Paul C. Wolf, Jane M. Packard

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

Few studies of monogamous canids have addressed regurgitation in the context of extended parental care and alloparental care within family groups. We studied food transfer by regurgitation in a pack of wolves on Ellesmere Island, North West Territories, Canada, during 6 summers from 1988 through 1996. All adult wolves, including yearlings and a post-reproductive female, regurgitated food. Although individuals regurgitated up to five times per bout, the overall ratio of regurgitations per bout was 1.5. Pups were more likely to receive regurgitations (81%) than the breeding female (14%) or auxiliaries (6%). The breeding male regurgitated mostly to the breeding female …


Twenty-Year Home-Range Dynamics Of A White-Tailed Deer Matriline, Michael E. Nelson, L. D. Mech Jan 1999

Twenty-Year Home-Range Dynamics Of A White-Tailed Deer Matriline, Michael E. Nelson, L. D. Mech

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

We examined the seasonal migration and home-range dynamics of a multigeneration white-tailed deer (Odocoileus virginianus) matriline comprising six females from four generations spanning a 20-year period in northeastern Minnesota. All, from the matriarch to her great-granddaughter, migrated to the same summer and winter ranges, the longest individual record being 14.5 years. Three maternal females concurrently occupied exclusive fawning sites within their ancestral matriarch’s summer range, while two nonmaternal females explored new areas and ranged near their mothers. One great-granddaughter expanded her summer range 1 km beyond the matriarch’s summer range while essentially vacating half of her ancestors’ range …

Changes In Small Mammal Community Attributes Associated With Increasing Pine Stand Age In Managed Pine Plantations In Southeastern Virginia, James Douglas Dolan Oct 1998

Changes In Small Mammal Community Attributes Associated With Increasing Pine Stand Age In Managed Pine Plantations In Southeastern Virginia, James Douglas Dolan

Biological Sciences Theses & Dissertations

Loblolly pine plantations were examined at different ages to identify small mammal community attributes in relation to the succession of the plant community. Forest floor and understory plant communities were characterized. Small mammals were collected by Fitch (live) traps and pitfall traps in four age classes during five seasons of study. Fitch live traps and pitfall traps were used in conjunction with one another to obtain the most accurate depiction of the small mammal community. Fitch traps accounted for 65 % of small mammal captures and 7 of 9 species captured. Small mammal abundance and biomass declined with increasing stand …

At 183 m depth, the bank is 179 km long. The Grenadines cover the bank to its northern end, but the bank extends for 39 km south of Grenada with no islands. During the last Ice Age, Grenada and the …


Abundance And Seasonal Distribution Of The Marbled Murrelet In Puget Sound And Hood Canal In Fall And Winter, Richard Anthony Jensen Merizon Jun 1998

Abundance And Seasonal Distribution Of The Marbled Murrelet In Puget Sound And Hood Canal In Fall And Winter, Richard Anthony Jensen Merizon

Dissertations and Theses

The greater Puget Sound area is home to a diversity of seabirds, however with encroaching human recreational and economic use of these areas these birds are facing unique threats. It is vitally important that we understand where these seabirds occur in order to minimize the risks associated with human influences. Intensive and extensive transects were used to collect data on seasonal distribution and abundance of seabirds, specifically marbled murrelets (Brachyramphus marmoratus), in Puget Sound and Hood Canal. Surveys were conducted from the water during the fall and winter in 1995 and 1996 and summer of 1997. Marbled murrelets were abundant …

Natural History Of The Southern Short-Tailed Shrew, Blarina Carolinensis, Hugh H. Genoways, Jerry R. Choate Feb 1998

Natural History Of The Southern Short-Tailed Shrew, Blarina Carolinensis, Hugh H. Genoways, Jerry R. Choate

University of Nebraska State Museum: Mammalogy Papers

The southern short-tailed shrew, Blarina carolinensis, inhabits a broad range of ecological situations in the southeastern United States and, in many areas, is among the two or three most abundant species of small mammals. Nevertheless, its natural history is poorly known and much of what researchers assumed was fairly well understood about this species actually resulted from work on another species (Blarina brevicauda) and may not be correct in all instances. This problem resulted when modem systematic methods revealed that the wide-ranging and well-studied species known at that time as Blarina brevicauda actually consisted of three species …

The Evolution Of Primate Malaria Parasites Based On The Gene Encoding Cytochrome B From The Linear Mitochondrial Genome, Ananias A. Escalante, Denise E. Freeland, William E. Collins, Altaf A. Lal Jan 1998

The Evolution Of Primate Malaria Parasites Based On The Gene Encoding Cytochrome B From The Linear Mitochondrial Genome, Ananias A. Escalante, Denise E. Freeland, William E. Collins, Altaf A. Lal

Harold W. Manter Laboratory of Parasitology: Library Materials

We report a phylogenetic analysis of primate malaria parasites based on the gene encoding the cytochrome b protein from the mitochondrial genome. We have studied 17 species of Plasmodium, including 14 parasitic in primates. In our analysis, four species were used for rooting the Plasmodium phylogenetic tree: two from closely related genera (Hepatocystis sp. and Haemoproteus columbae) and two other Apicomplexa (Toxoplasma gondii and Theileria parva). We found that primate malaria parasites form a monophyletic group, with the only exception being the Plasmodium falciparum–Plasmodium reichenowi lineage. Phylogenetic analyses that include two species …

Metazoan Parasites And Other Symbionts Of Cetaceans In The Caribbean, Antonio A. Mignucci-Giannoni, Eric P. Hoberg, Doug Siegel-Causey, Ernest H. Williams Jr.

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The parasite fauna in cetaceans from Puerto Rico, the Virgin Islands, and the larger Caribbean region is poorly known. We provide the first records for parasite biodiversity among a diverse assemblage of cetaceans from the Caribbean Sea. Internal and external parasites and commensals were collected from stranded whales and dolphins salvaged in Puerto Rico, the United States and British Virgin Islands, Jamaica, and Venezuela between 1989 and 1997. A total of 47 individuals of 16 species of whales and dolphins (15 odontocetes and one mysticete) were examined. Overall, parasites and commensals were found in 34 (72.3%) animals, representing 13 species …

Terrestrial Natural Communities Of Nebraska - Version I, Gerry Steinauer, Steven B. Rolfsmeier

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

The Nebraska Natural Heritage Program has been collecting information and data including published literature, field observations and vegetation plot data over the last 10 years of development of Nebraska’s natural community classification. The classification contains 27 wetland and 36 upland communities including forest, woodland, shrubland, herbaceous, and sparsely vegetated (e.g. rock outcrop) types. The community types were distinguished primarily on plant species composition and to a lesser extent on soils, hydrology and geographic location. The classification contains descriptions of each community type that include dominant species, soils, range, and other ecological information. The classification is designed to be flexible enough …


Survey Of Mollusks Of The Niobrara River: Final Report, Patricia W. Freeman, Keith Perkins Sep 1997

Survey Of Mollusks Of The Niobrara River: Final Report, Patricia W. Freeman, Keith Perkins

School of Natural Resources: Faculty Publications

We surveyed the mollusks of the Niobrara River in Nebraska from 1992–1996. We found two species of unionid clams and ten species of snails that either must live in water or near water. Both clams and snails are poorly sampled in the state, however we attribute the low number of species of unionid clams in the Niobrara to its cold, fast flow and rocky bottom. In contrast, the Platte River is slower moving with a muddy bottom and has at least 11 species of unionid clams. Each species has been mapped with latitude/longitude coordinates. Specimens have been curated and are …

Habitat Use By Migrant Whooping Cranes In Saskatchewan, Brian W. Johns, Eric J. Woodsworth, Ed A. Driver Jan 1997

Habitat Use By Migrant Whooping Cranes In Saskatchewan, Brian W. Johns, Eric J. Woodsworth, Ed A. Driver

Proceedings of the North American Crane Workshop

We investigated habitat use by migrating whooping cranes (Grus americana) in Saskatchewan between 1986 and 1990. At foraging and roosting sites and a sample of randomly selected sites we measured various habitat parameters. Palustrine and lacustrine wetlands were the most frequently used wetlands. Temporary and seasonal wetlands were the primary roost habitat during spring migration, and semi-permanent and permanent wetlands were frequently used during the fall. Cranes were attracted to areas of higher than average wetland density. Land use within 2 km of roost sites was intensively modified by man. Cereal crops were the most used feeding areas. …


Availability Of Stopover Habitat For Migrant Whooping Cranes In Nebraska, Dale W. Stahlecker Jan 1997

Availability Of Stopover Habitat For Migrant Whooping Cranes In Nebraska, Dale W. Stahlecker

Proceedings of the North American Crane Workshop

Four stratified random samples of 512 National Wetland Inventory (NWI) maps within the central Nebraska portion of the Wood Buffalo-Aransas whooping crane (Grus americana) migration corridor were used to evaluate the availability of wetland roost sites. Wetlands were eliminated as potential roosts if visibility was obscured by vegetation or slope, if certain human activities occurred within 100-800 ro, or if water < 30 em deep was not available. Seasonal emergent wetlands, available as roosts primarily in spring, dominated all samples, particularly in the nortb. Sixty-five percent of all wetlands >0.04 ha passed map review and 52 % passed when ground-truthed. NWI map review was a good predictor of both suitability (63 % correct) and unsuitability (73 % correct). More than one-half of all open and emergent …


Woody Vegetation Expansion And Continuing Declines In Open Channel Habitat On The Platte River In Nebraska, Paul J. Currier Jan 1997

Woody Vegetation Expansion And Continuing Declines In Open Channel Habitat On The Platte River In Nebraska, Paul J. Currier

Proceedings of the North American Crane Workshop

Aerial videography in 1988 and 1994 of the same selected segments of the Big Bend reach of the Platte River in central Nebraska was compared. During this 6-year period, channel area declined 4 to 41 % (median 26%). In river segments where the channel had already narrowed significantly and at sites where channel habitat is actively managed declines were less (17-18%). These substantial changes occurred during a time that included a relatively low flow period (1990-92). Flows during the summer gertttination and establishment period (mid-May through August) for cottonwood (Populus deltoides) and willow (Salix spp.), the …
