United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
WOLVES CAN LIVE almost anywhere in the Northern Hemisphere, and almost everywhere they do, they are an issue. In the vast emptiness of the northern tundra or the Arabian desert, on the outskirts of a European town or in the safety of an American national park, in meager agricultural lands in India or mountains in rich Norway or Switzerland, wolves always attract people's attention. Wolves form a key part of many ecosystems, and they are considered charismatic creatures by most human cultures. Thus they polarize public opinion and make headlines year after year.
If we look back 6o years to …

Bats Of Nevis, Northern Lesser Antilles, Scott C. Pedersen, Hugh H. Genoways, Matthew N. Morton, James W. Johnson, Siân E. Courts
University of Nebraska State Museum: Mammalogy Papers
Only one species of bat, Molossus molossus, previously has been documented as occurring on the northern Lesser Antillean island of Nevis. Field research and reviews of existing museum collections have provided documentation based on voucher specimens for an additional seven species occurring on the island — Noctilio leporinus, Brachyphylla cavernarum, Monophyllus plethodon, Ardops nichollsi, Artibeus jamaicensis, Natalus stramineus, and Tadarida brasiliensis. The biological diversity of the chiropteran fauna on Nevis is similar to that found on other islands in the northern Lesser Antilles. Ecologically, this is a simple chiropteran fauna, including one …

Avian Use Of Chinese Tallow Seeds In Coastal Texas (Abstract), Warren C. Conway
Avian Use Of Chinese Tallow Seeds In Coastal Texas (Abstract), Warren C. Conway
Faculty Publications
The Chinese tallow tree (Sapium sebiferum) (Euphorbiaceae) was introduced into coastal Texas in the late 1800s and forms monotypic woodlands once naturalized. However, few studies have examined avian use of tallow seeds during fall migration in coastal Texas. We documented use of Chinese tallow seeds and compared foraging frequency on Chinese tallow seeds among permanent, summer, and winter residents and migrants. We also tested the hypothesis that Chinese tallow seed germination was enhanced by foraging activities of yellow-rumped warblers (Dendroica coronata), the most common species observed foraging on tallow seeds. During fall migration 1995 and 1996, …

Pasture Condition Guides For The Pilbara, A L. Payne, A A. Mitchell
Pasture Condition Guides For The Pilbara, A L. Payne, A A. Mitchell
Agriculture reports
These pasture condition guides are relevant to about 192 000 square kilometres of the Pilbara region of Western Australia. The rangeland of the Pilbara can be separated into 12 very broad pasture types. The ‘pasture type’ is not strictly a botanical classification because, in determining such a class of pastoral lands, the perennial plant species that contribute to stock production have an over-riding importance. Even so, each pasture type represents a broad group of similar vegetation associations or ‘site types’ which will have similar management requirements for pastoralism. The aim of this publication is to provide pastoralists with descriptions and …

Endangered And Threatened Wildlife And Plants: Designation Of Critical Habitat For The Topeka Shiner, Proposed Rule
Endangered Species Bulletin
We, the U.S. Fish and Wildlife Service, propose designation of critical habitat pursuant to the Endangered Species Act of 1973, as amended, for the Topeka shiner (Notropis topeka). This proposal is made in response to a court settlement in Biodiversity Legal Foundation et al. v. Ralph Morganweck et al. C00–D–1180, committing the Service to submit for publication in the Federal Register a proposal to withdraw the existing ‘‘not prudent’’ critical habitat determination together with a new proposed critical habitat determination for the Topeka shiner by August 13, 2002. We are proposing to designate as critical habitat a …

Fisheries Research Report No. 133 - Preliminary Assessment And Seasonal Fluctuations In The Fish Biota Inhabiting The Concentrator Ponds Of Dampier Salt, Port Hedland, With Options For The Potential Application Of Results, Brett Molony, Gareth Parry
Fisheries Research Report No. 133 - Preliminary Assessment And Seasonal Fluctuations In The Fish Biota Inhabiting The Concentrator Ponds Of Dampier Salt, Port Hedland, With Options For The Potential Application Of Results, Brett Molony, Gareth Parry
Fisheries Research Reports
The concentrator ponds (CPs) of Dampier Salt, Port Hedland, cover an area in excess of 7 300 ha. Water is pumped from two adjacent, mangrove-lined estuaries at certain times of the year and small and larvae fishes are carried into the ponds, becoming trapped. A survey of the fish biota within the CPs was undertaken at four time periods between May 2000 and February 2001 to identify the species of fishes present and to estimate their abundances and distribution throughout the CPs. Further, the Artemia resources within the CPs were also assessed for identification of species and quality.

Fisheries Research Reports
The State Territorial Waters surrounding the Abrolhos Islands are gazetted as a Fish Habitat Protection Area and vested with the Minister for Fisheries under the Fish Resources Management Act 1994. Three Fisheries Management Papers have identified management priorities for the marine environment at the Abrolhos Islands:
- Management of the Houtman Abrolhos System
- Aquaculture Plan for the Houtman Abrolhos Islands
- Sustainable Tourism Plan for the Houtman Abrolhos Islands.
These plans and other national and international obligations to examine the effect of extractive and non-extractive anthropogenic activities on marine habitats (eg. Environment Protection and Biodiversity Conservation Act 1999) led to …

Genomic Microsatellites As Evolutionary Chronometers: A Test In Wild Cats, Carlos A. Driscoll, Marilyn Menotti-Raymond, George Nelson, David Goldstein, Stephen J. O'Brien
Biology Faculty Articles
Nuclear microsatellite loci (2- to 5-bp tandem repeats) would seem to be ideal markers for population genetic monitoring because of their abundant polymorphism, wide dispersal in vertebrate genomes, near selective neutrality, and ease of assessment; however, questions about their mode of generation, mutation rates and ascertainment bias have limited interpretation considerably. We have assessed the patterns of genomic diversity for ninety feline microsatellite loci among previously characterized populations of cheetahs, lions and pumas in recapitulating demographic history. The results imply that the microsatellite diversity measures (heterozygosity, allele reconstitution and microsatellite allele variance) offer proportionate indicators, albeit with large variance, of …

Rapid Ecological Assessment Of The Northern Mixedgrass Prairie Ecoregion (Nebraska Portion), Gerry Steinauer
Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts
This study was conducted as part of The Nature Conservancy’s (TNC) project to conduct ecoregional conservation planning throughout the continental United States. TNC contracted with the Nebraska Game and Parks Commission (NGPC) to conduct a rapid ecological assessment (REA) of the portion of the Northern Mixedgrass Prairie ecoregion (NMGP) occurring in Nebraska. This report concludes that agreement. Roughly the northern 1/5 of central Nebraska occurs within the NMGP (Figure 1). This ecoregion also includes extensive area of central South Dakota and central North Dakota. The objective of this study was to conduct a REA of the untilled landscapes within the …

Clone Size Of Andropogon Gerardii Vitman (Big Bluestem) At Konza Prairie, Kansas, Kathleen H. Keeler, Charles F. Williams, Linda S. Vescio
School of Biological Sciences: Faculty Publications
Clone size of plants of Andropogon gerardii from Konza Prairie Biological Station, Manhattan, Kansas was estimated from spatial patterns of genetic variation, using proteins detected by starch gel electrophoresis and DNA content (ploidy) measured by flow cytometry. Unique multi-locus protein banding patterns and differences in ploidy were used to exclude plants as members of the same clone. Individual clones averaged about 2 m in diameter and areas of prairie of 100 m2 were calculated to contain an average of 31.8 genetic individuals.

Development of the muskox protostrongylid lungworm, Umingmakstrongylus pallikuukensis, in its slug intermediate host, Deroceras laeve, was investigated under field conditions in the Arctic. Every two weeks, from 19 June to 28 August 1997, groups of ten experimentally infected slugs were placed in tundra enclosures in a mesic sedge meadow near Kugluktuk, Nunavut, Canada. First-stage larvae (L1) infecting slugs on or before 17 July developed to third-stage larvae (L3) in 4–6 weeks. Intensity of L3 in slugs peaked at 6–8 weeks post infection (PI) and then progressively declined by 10, 12, and 48–50 weeks PI. Abundance of L3 in …

Burgeoning awareness about biodiversity emphasizes the fundamental importance of museum collections and the contributions of systematists and taxonomists in documenting the structure and history of the biosphere. An essential role is served by this infrastructure in collecting, preparing, analyzing, and disseminating information about the specimens that represent species, document a range of complex biological associations from symbioses to parasitism, and form the tapestry and the myriad facets of biodiversity (e.g., Wilson, 2000). As parasitologists we can examine how we may contribute to this broader documentation and understanding of global biodiversity, and we can articulate and communicate our role as vital …
Protostrongylus Stilesi (Nematoda: Protostrongylidae): Ecological Isolation And Putative Host-Switching Between Dall’S Sheep And Muskoxen In A Contact Zone, Eric P. Hoberg, Susan J. Kutz, John Nagy, Emily Jenkins, Brett Elkin, Marsha Branigan, Dorothy Cooley
Protostrongylus Stilesi (Nematoda: Protostrongylidae): Ecological Isolation And Putative Host-Switching Between Dall’S Sheep And Muskoxen In A Contact Zone, Eric P. Hoberg, Susan J. Kutz, John Nagy, Emily Jenkins, Brett Elkin, Marsha Branigan, Dorothy Cooley
Harold W. Manter Laboratory of Parasitology: Faculty Publications
The occurrence of Protostrongylus stilesi in a population of introduced muskoxen, Ovibos moschatus wardi, on the Arctic Coastal Plain, Yukon Territory (YT) and Northwest Territories (NT), Canada, is consistent with a contemporary colonization event from Dall’s sheep, Ovis dalli dalli, which indicates that host specificity may be ecologically based and contextual for this parasite. Colonization of muskoxen by P. stilesi may be a predictable event in zones of sympatry with Dall’s sheep; exposure to infection may coincide with occupation of winter ranges of Dall’s sheep by muskoxen during the summer season. Disruption of contemporary ecological isolating barriers can …
