Métodos Cuantitativos Para La Conservación De Los Vertebrados, Michael J. Conroy, John P. Carroll, Juan Carlos Senar, Jeffrey J. Thompson

School of Natural Resources: Faculty Publications

Este libro es destinado para el uso por biólogos del campo y otras personas, incluso biólogos de campo en el futuro que podrían estar en un curso de la universidad y trabajando en estudios y conservación de animales. Nuestro objetivo es que los biólogos usen este libro como (haciendo apología a nuestro colega Evan Cooch) una “introducción suave” al campo de la ecología cuantitativa. Esperamos convencer a los lectores que los métodos y aproximaciones del libro no son solo para los matemáticos, estadísticos y programadores de computadoras, sino que de hecho son herramientas esenciales para practicar la conservación en el …

Amphibian Occupancy And Functional Connectivity Of Restored Wetlands In The Missouri River Floodplain, Michelle L. Hellman

School of Natural Resources: Dissertations, Theses, and Student Research

Wetland decline may threaten many taxa including shorebirds, amphibians, and fish. As agencies increase restoration of wetland habitat, monitoring is crucial to inform the process. Permeable skin sensitive to water quality and biphasic life histories requiring both terrestrial and aquatic habitat make amphibians good indicators of wetland health. I modeled amphibian occupancy in restored Missouri River bends to determine habitat characteristics associated with the presence of amphibians.

Occupancy modeling acknowledges imperfect detection and allows the inclusion of detection covariates. To assess detection I examined two methods currently used to assess anuran occupancy in wetlands, aural anuran surveys and tadpole dip-netting. …

Ramphotyphlops Braminus (Brahminy Blindsnake): Predation, Louis A. Somma

Papers in Herpetology

Ramphotyphlops braminus currently has the most widespread, near worldwide, nonindigenous distribution of any snake. In Florida, USA, R. braminus is rapidly expanding its distribution.

The stomach contents of a necropsied Dasypus novemcinctus (nine-banded armadillo) found on the premises of the Florida Department of Agriculture and Consumer Services in Gaisesville in March 2011 included an intact adult R. braminus. Dasypus novemcinctus is nonindigenous in Florida. It has a primarily insectivorous diet but occasionally preys upon small vertebrates, including reptiles. This is the first record of R. braminus in the diet of D. novemcinctus.

Impact Of Alternative Range Management Systems On Grasslands In The Central Platte River Valley, Nebraska, Luis E. Ramirez

School of Natural Resources: Dissertations, Theses, and Student Research

Land management strategies can directly and indirectly affect plant assemblages and their behavior. Little research has been performed in south central Nebraska to quantify the effect of fire and grazing interactions on species composition, vegetation structure, forage quality, and potential cost associated with land management.

I evaluate the effect of season-long continuous, patch-burning, and rotational grazing approaches on vegetation and ranching costs to determine their value as conservation tools. This study includes data collected between 2007 and 2009 from grasslands in south central Nebraska. I found that land management influence plant assemblages by shifting communities when grazing and/or fire are …

Origin And Conservation Genetics Of Threatened Ute Ladies’-Tresses, Spiranthes Diluvialis (Orchidaceae), Allen L. Szalanski, Gerry Steinauer, Richard Bischof, Jessica Lynn Petersen

Department of Animal Science: Faculty Publications

The Ute ladies’-tresses, Spiranthes diluvialis, is listed as a threatened orchid in west-central United States by the Federal government. Information on its origin and patterns of genetic variation is needed to develop effective conservation strategies for this species. DNA sequencing and polymerase chain reaction–restriction fragment length polymorphism (PCR-RFLP) was used to evaluate genetic variation and structure of 23 populations of S. diluvialis. In addition, four congeneric species were analyzed to determine possible origins of the putative allotetraploid S. diluvialis. DNA sequencing and PCR-RFLP analysis of the nuclear ribosomal internal transcribed spacer (ITS) and mitochondrial and chloroplast DNA …

Catalog Of The Recent Scandentia And Primates In The Carnegie Museum Of Natural History, Suzanne B. Mclaren, Duane A. Schlitter, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

The Section of Mammals, Carnegie Museum of Natural History, houses six specimens of Recent tree shrews and 611 specimens of Recent primates. The only family in the Order Scandentia is Tupaiidae. Primate families represented are Lemuridae, Lorisidae, Cebidae, Callitrichidae, Cercopithecidae, Pongidae, and Hominidae. For each specimen the following data are recorded: locality; date collected; catalog number; sex; age; nature of specimen; condition of specimen and comments. The latter category gives information on the condition of the skin and skeletal material, and gives information on the availability of the specimen.
