University of Nebraska State Museum: Mammalogy Papers

An inventory of mammals in the vicinity of Brownsberg Nature Park, Suriname, incorporated a number of different sampling methods including examining museum voucher specimens, an animal-rescue operation, transect surveys, camera photo-traps, and interviews with local inhabitants. We document a total of 125 mammal species present in the Park. These include ten opossums, five pilosans, four armadillos, 58 bats, eight monkeys, 13 carnivores, one tapir, four artiodactyls, and 22 rodents. Nine of these species are reported for the first time from Suriname: one mouse opossum (Marmosops pinheiroi); one naked-backed moustached bat (Pteronotus gymnonotus); four fruit-eating bats ( …

Preliminary Survey Of The Mayflies (Ephemeroptera) And Caddisflies (Trichoptera) Of Big Bend Ranch State Park And Big Bend National Park, David E. Baumgardner, David E. Bowles

College of Natural and Applied Sciences

The mayfly (Insecta: Ephemeroptera) and caddisfly (Insecta: Trichoptera) fauna of Big Bend National Park and Big Bend Ranch State Park are reported based upon numerous records. For mayflies, sixteen species representing four families and twelve genera are reported. By comparison, thirty-five species of caddisflies were collected during this study representing seventeen genera and nine families. Although the Rio Grande supports the greatest diversity of mayflies (n=9) and caddisflies (n=14), numerous spring-fed creeks throughout the park also support a wide variety of species. A general lack of data on the distribution and abundance of invertebrates in Big Bend National and State …

Use Of 16s Rrna Gene Terminal Restriction Fragment Analysis To Assess The Impact Of Solids Retention Time On The Bacterial Diversity Of Activated Sludge, Pascal E. Saikaly, Peter George Stroot, Daniel B. Oerther

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Terminal restriction fragment length polymorphism (T-RFLP) analysis of 16S rRNA genes was used to investigate the reproducibility and stability in the bacterial community structure of laboratory-scale sequencing batch bioreactors (SBR) and to assess the impact of solids retention time (SRT) on bacterial diversity. Two experiments were performed. In each experiment two sets of replicate SBRs were operated for a periods of three times the SRT. One set was operated at an SRT of 2 days and another set was operated at an SRT of 8 days. Samples for T-RFLP analysis were collected from the two sets of replicate reactors. HhaI, …

The Effectiveness Of The Endangered Species Act: A Quantitative Analysis, Martin F.J. Taylor, Kieran F. Suckling, Jeffrey J. Rachlinski

Cornell Law Faculty Publications

Population trends for 1095 species listed as threatened and endangered under the Endangered Species Act were correlated with the length of time the species were listed and the presence or absence of critical habitat and recovery plans. Species with critical habitat for two or more years were more than twice as likely to have an improving population trend in the late 1990s, and less than half as likely to be declining in the early 1990s, as species without. Species with dedicated recovery plans for two or more years were significantly more likely to be improving and less likely to be …

Recent Records Of Formerly Extirpated Carnivores In Nebraska, Justin D. Hoffman, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

By the early 1900's, several large carnivores had been extirpated from Nebraska as a result of unrestricted hunting and trapping by early European settlers. Recently, there have been several confirmed records of carnivores that were once extirpated from Nebraska. In our study, we present new data for five species that recently were documented in Nebraska: Lynx canadensis, Ursus americanus, Canis lupus, Puma concolor, and Lontra canadensis. Restoration programs and legal protection afforded to these species in Nebraska and in adjacent states have allowed population numbers to increase. Because of the increase in populations of these …

Increasing Interest In Parasitology At The Past Three International Mammalogical Congresses Held In 1997, 2001 And 2005: Mammals, Parasites, Zoonoses And Biodiversity, Scott Lyell Gardner, Mitsuhiko Asakawa, Luis A. Ruedas, Kenichi Takahashi

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

We summarized the data from the past three TTC (now IMC) meetings to examine the potential trends in presentation of parasites of mammals at the meeting. The lists include titles and authors of papers given in symposia, poster sessions, and oral presentations related to diseases, zoonoses, parasites, and causative agents of diseases of sylvatic mammals. Our analysis shows that there has been an increase in the number of papers (from 2.8% in 1997 to 5.1% in 2005) presented at the International Mammalogical Meetings. We also show that there are potentially more than 27,000 species of parasites (broadly defined) currently inhabiting …

Predicting Plant Extinction Based On Species-Area Curves In Prairie Fragments With High Beta Richness, Brian J. Wilsey, Leanne M. Martin, H. Wayne Polley

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Species-area relationships and island biogeography theory are commonly used to predict how species richness will decline with fragmentation. There are a variety of largely untested assumptions in these approaches, including the assumptions that populations are distributed uniformly before fragmentation, and that local extinctions are due to effects of small population sizes. If populations are not distributed uniformly, then populations can be abundant locally but rare globally. This would cause extinction rates to be smaller than predicted.We tested extinction theory by developing estimates of the number of plant species that should be present in small tallgrass prairie fragments and then testing …

Natural Resource Management Issues For The South Coast Regional Strategy, B Nicholas

Resource management technical reports

This report has been prepared by the Agricultural Resource Management Program of the Department of Agriculture to assist SCRIPT (South Coast Regional Initiative Planning Team) in preparing the regional strategy. It records the key natural resource management issues threatening agricultural land on the south coast of Western Australia. Managing agricultural land effectively should be a priority in reducing the risks of land degradation on all assets-productive agricultural land, biodiversity and waterways.

Wagin-Woodanilling (Zone 5) : Catchment Appraisal 2005, K Ohlsen, T Schulz, T W. Mathwin, Gina Pemberton, Henry Brockman, J Firth, Mitchell Davies, Heather M. Percy

Resource management technical reports

The aim of this report is to assess the current extent of salinity and other natural resource degradation issues and provide landholders with the best current management options to address natural resource management issues and enhance sustainable agricultural production.
