Health And Fertility Implications Related To Seasonal Changes In Kidney Fat Index Of White-Tailed Jackrabbits In South Dakota, Dustin Schaible, Charles D. Dieter

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

White-tailed jackrabbit (Lepus townsendii) populations in the Northern Plains have been in a general decline for the past decade or longer. A suggested reason for this population decline was reduced body condition of individual jackrabbits due to habitat changes. In order to evaluate body condition, we determined the kidney fat index of 314 white-tailed jackrabbits harvested in 44 counties throughout South Dakota. We removed and weighed kidneys and all perirenal fat associated with the kidneys from collected jackrabbits. We measured kidney weight to determine times of high metabolic activity as indicated by an increase in mass. Body condition was …

Review Of Nature's Ghosts: Confronting Extinction From The Age Of Jefferson To The Age Of Ecology. By Mark V. Barrow, Jr., Peter A. Bednekoff

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

The saving of bison occupies a central place in Nature's Ghosts, but Mark Barrow's chronicle extends over a century both before and after. The story starts with Thomas Jefferson and fossils that came to be recognized as mastodons, mammoths, and giant ground sloths. "Jefferson and most of his contemporaries were certain that the natural world was orderly, static, and new." In such a worldview, extinction was unthinkable. Fossil evidence plus the historical extinctions of dodos, moas, and great auks forced reconsideration.

This book ranges across centuries and continents, and only a few parts of it are explicitly about the Great …

Historic And Contemporary Trends Of The Conservation Reserve Program And Ring-Necked Pheasants In South Dakota, Christopher R. Laingen

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Over the past century, the interactions between agricultural land use and government cropland retirement programs have affected pheasant population change. Two government land retirement programs that returned croplands to grasslands, Soil Bank in the 1960s and the current Conservation Reserve Program (CRP), help to illustrate these connections. From 2007 to 2010, South Dakota lost 41% of its CRP lands and experienced an 18% decline in pheasants per mile. However, because of where CRP expirations have occurred and where pheasant populations are found, some regional variability is seen. Western South Dakota (Region 1) had an 80% increase in pheasants per mile …

Using Euro-American Hunting Data To Assess Western Great Plains Biogeography, 1806-35, Cody Newton

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Historic accounts from the 19th-century western Great Plains contain significant information on Plains ungulates and other animals, particularly as they relate to provisioning the Euro-American travelers. Using data derived from these accounts, a quantitative assessment of the hunting success of the Pike, Long, Glenn, and Dodge expeditions of the early 19th century is presented to ascertain the conditions of these species in the region. These data are then used to assess historiographic models of bison overhunting. This analysis indicates that the western Southern Plains and western Central Plains had differing trajectories of overhunting explained by temporally variable human and environmental …

Review Of Cougar: Ecology And Conservation. Edited By Maurice Hornocker And Sharon Negri., Oranit Gilad

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Historically, cougars (mountain lions, pumas, or panthers) had an extensive distribution throughout the Americas, ranging from British Columbia in North America to Patagonia at South America's tip. As a native species and a large obligate carnivore, the cougar has a complex relationship with the human population in the Americas. This current book-the product of multiple authors, all with hands-on experience in cougar work, and written in a clear manner appropriate to most audiences-is an important addition to the scientific literature in the field of carnivore conservation in the New World. As a product of many authors, Cougar: Ecology and Conservation …

Review Of Whooping Crane: Images From The Wild. By Klaus Nigge., Paul Johnsgard

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

When asked to review this book I hadn't yet heard of it or its author, a wildlife photographer well known in his native Germany and the author of four photographic books published there, so I was eager to read it. The book is visually impressive, measuring 11" x 12", making it a true coffee-table production. Inside is a well-written 2S-page "primer" on whooping cranes by Krista Schlyer dealing with cranes in myth and legend, crane vocalizations and displays, and breeding biology. She also provides a brief survey of the whooping crane's population history, its near brush with extinction, and the …

Are Western Australian Waters The Least Productive Waters For Finfish Across Two Oceans? A Review With A Focus On Finfish Resources In The Kimberley Region And North Coast Bioregion, B. W. Molony, S. J. Newman, L. Loll, R C J Lenanton, B. Wise

Fisheries Research Articles

The marine ecosystems of Western Australia, including those in the Kimberley, are classified as being of moderate to low productivity. This is primarily a consequence of the influence of the Leeuwin Current, the eastern boundary current that flows poleward delivering warm, low nutrient waters, and only sporadic short-term upwelling events to shelf habitats off the Western Australian coast. This, coupled with little riverine inflow from old weathered terrestrial systems, results in low levels of primary and secondary production in habitats along most of the coast. The consequence is that finfish fisheries in the Kimberley and throughout the State typically land …

A Comparison Of Adrenal In Toad-Eating And Nontoad-Eating Snakes, Shabnam Mohammadi

Biological Sciences Theses & Dissertations

Toads are chemically defended by bufadienolides, a class of cardiotonic steroids lethal to most predators, including many snakes. Bufadienolides bind to Na+K +-ATPase, inhibiting their ability to transport ions. In cardiocytes, this inhibition cause arrhythmia and severely increased contraction strength, which, if prolonged, lead to death. However, several snakes are resistant to bufadienolides and consume toads with no ill effects. Adrenal glands produce hormones that are important for the maintenance of Na+K +ATPase, and may therefore play an important role in countering the negative effects of bufadienolides. Indeed, the toad-eating specialist Heterodon platirhinos has been known to possess enlarged, and …

Population Dynamics Of Sheepshead (Archosargus Probatocephalus; Walbaum 1792) In The Chesapeake Bay Region: A Comparison To Other Areas And An Assessment Of Their Current Status, Joseph Charles Ballenger

OES Theses and Dissertations

Sheepshead recently have seen an increase in fishing pressure in Virginian waters of the Chesapeake Bay. This increase in fishing pressure has led to demands to install effective management measures to protect the fishery. However, no study regarding the population dynamics, and thus potential yield, of sheepshead has been conducted north of Cape Hatteras. We addressed the need for information regarding the population dynamics of Chesapeake Bay sheepshead by investigating their age distribution, growth rate and reproductive biology. We used this information to construct yield-per-recruit models, which local management agencies may use in the formation of scientifically based management measures. …

Ecology And Management Of Channel Catfish Ictalurus Punctatus And Flathead Catfish Pylodictis Olivaris Populations In The Missouri River, Ne, Cameron Wesley Goble

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

Channel catfish Ictalurus punctatus and flathead catfish Pylodictis olivaris are two of the most important freshwater recreational or commercial species in the United States. Catfish populations in the Missouri River are important resources to the people of Nebraska and surrounding states. The objective of my study was to determine the present status of catfish populations in the Missouri River, Nebraska. Specifically I evaluated population characteristics such as relative abundance, population size and density, size structure, condition, age structure, growth, and mortality. I used a stratified random sampling design and generalized linear mixed modeling approach to assess differences in population characteristics …

Preference Of White-Tailed Deer For Corn Hybrids And Agricultural Husbandry Practices During The Growing Season, Joshua A. Delger, Kevin L. Monteith, Lowell E. Schmitz, Jonathan A. Jenks

Natural Resource Management Faculty Publications

Damage to field corn (Zea mays) by white-tailed deer (Odocoileus virginianus) can be substantial, resulting in millions of dollars lost annually. Numerous methods exist to minimize deer depredation, but all have met with varying degrees of success. Currently, little information is available on preference of white-tailed deer for corn hybrids during the growing season and how that preference might affect depredation patterns. We used adult female white-tailed deer in captivity to study the effect of herbicide treatments on deer-use (treatment versus no treatment) of corn in 2005 and to document preference among specific corn hybrids in …

Identification And Characterization Of The Contact Zone Between Short-Tailed Shrews (Blarina) In Iowa And Missouri, Cody W. Thompson, R. S. Pfau, Jerry R. Choate, Hugh H. Genoways, Elmer J. Finck

University of Nebraska State Museum: Mammalogy Papers

Short-tailed shrews (genus Blarina Gray, 1838) are characterized by divergent karyotypes and are genetically distinct. Blarina species are similar morphologically but, in most cases, can be distinguished morphometrically. Blarina distributions tend to be parapatric along well-defined contact zones; however, it has been suggested that the northern short-tailed shrew (Blarina brevicauda (Say, 1823)) and Elliot’s short-tailed shrew (Blarina hylophaga Elliot, 1899) occur sympatrically in Iowa and Missouri. To evaluate this possibility, 179 specimens were collected in southwestern Iowa and northwestern Missouri. Karyotypes and total length were used for field identification, and amplified fragment length polymorphism (AFLP) analysis was used …

A Habitat And Abundance Study Of Octopus Cyanea In Southwest Madagascar, Michael Belazis

Independent Study Project (ISP) Collection

The increased demand for marine products has fueled a worldwide overexpansion of the fishing industry. Furthermore, the shift of lower-income countries, like Madagascar, from subsistence to market-based cash economies has led to increased fishing pressures on marine resources. Recent commercialization of fisheries in Southwest Madagascar has caused an over-exploitation of octopus in the Toliara region. In an effort to create sustainable octopus fisheries, Blue Ventures, a UK-based NGO, created the world’s first community run Marine Protected Area (MPA) for octopus near Andavadoaka called Velondriake.

Here, the results of an Octopus cyanea habitat study performed near Beheloke, a fishing village on …

Examining Trends In Taste Preferences, Market Demand, And Annual Catch In An Indigenous Marine Turtle Fishery In Southwest Madagascar, Kristin Jones

Independent Study Project (ISP) Collection

The worldwide exploitation of marine turtles has been common throughout human history, turtle products including carapaces for decoration and use, skin for leather, and eggs and meat for consumption. The hunting of marine turtles has long established economic importance among Madagascar's coastal inhabitants and is an activity traditionally associated with integral cultural and spiritual values. Due to overexploitation and a combination of relatively newer threats such as pollution, habitat loss, and incidental fisheries take, however, all marine turtle species in the Indian Ocean are considered to be endangered or critically endangered. Although Madagascar's marine turtles have been legally protected from …

Adult Female Activity Time Budgets In Red-Bellied Lemurs (Eulemur Rubriventer) And Infant Survival: Ranomafana National Park, Frances Hardy

Independent Study Project (ISP) Collection

My research during the independent study period focuses on the relationship between activity time budgets of adult female red-bellied lemurs (Eulemur rubriventer) and infant survival. I conducted my research under the guidance of Centre ValBio in Ranomafana National Park. Red-bellied lemurs have a clear three month birth peak from Aug-Oct, but up to 30% of infants in a single year can be born outside of this birth peak, however, survival for out-of-season infants is strikingly low compared to in-season infants, 100% (n=4) of out-of-season infants died in one study conducted in 2009, whereas only 11% (n=18) of in-season …

Monitoring Nesting Trends And Hatchling Success Of The Green Turtle (Chelonia Mydas) Population On Mnemba Island, Zanzibar, Taylor Dunbar

Independent Study Project (ISP) Collection

The nesting trends and hatching success of Green sea turtles (Chelonia mydas) were studied on Mnemba Island. This study involved a continuation of data collection for the ongoing monitoring program of sea turtles on Mnemba Island. Data was collected from nesting females as well as from post hatching nest excavations. The data that has been collected over the course of ten years was then analyzed to examine trends over time as well as to assess the current status of the turtle population on Mnemba Island. Hatch success as a function of different seasons was analyzed. It has been concluded that …

Multilocus And Parametric Analyses Of The Evolutionary History Of The Amazonian Peacock Cichlids, The Genus Cichla (Teleostei: Cichlidae), Stuart Clayton Willis

School of Biological Sciences: Dissertations, Theses, and Student Research

Accurate knowledge of species boundaries and species phylogeny are fundamental to testing hypotheses of recent evolutionary processes, but the estimation of these partitions is challenging due both to inherent confusion about what is being estimated as well as the data available to estimate them. Using multilocus data from mtDNA, microsatellites, and nuclear locus sequences of over 1100 individuals, we delimited eight separately evolving species of Cichla rather than the 15 described. Among species we found evidence of rare but widespread introgressive hybridization, while within these species we observed evidence of long-term gene exchange and constrained evolutionary trajectories. In most cases …

Review Of Raptors Of New Mexico. Edited By Jean-Luc E. Cartron., Brian Millsap

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

As a raptor specialist, I eagerly look forward to the publication of state and regional books on birds of prey, typically rich with hard-to-find locally flavored information on distribution and biology. With the publication of Raptors of New Mexico, my home state has joined the ranks of the handful of states blessed with such volumes, and in fine form. This is an impressive work both in size and content, but the first thing anyone will notice are the photographs-hundreds, most top-notch, many capturing moods, scenes, and places unique to New Mexican raptors. In many ways the book is a showcase …

The 100th Meridian Initiative: A Strategic Approach To Prevent The Westward Spread Of Zebra Mussels And Other Aquatic Nuisance Species, Susan Mangin

United States Fish and Wildlife Service: Publications

Zebra mussels are prolific alien invaders that have rapidly become
established in waters of the eastern United States and Canada. These
natives of the Black, Caspian, Azov and Aral Sea drainage basins were first
discovered in Lake St. Clair near Detroit, Michigan, in 1988. By 1991, they
had spread throughout the Great Lakes basin and are now established
throughout the Mississippi River basin and are spreading west into
Oklahoma. Except for Oklahoma, zebra mussels have not been detected in
open waters of the West. However, without effective prevention measures,
their invasion into the West is a real and imminent possibility. …

Evolution Of A Major Drug Metabolizing Enzyme Defect In The Domestic Cat And Other Felidae: Phylogenetic Timing And The Role Of Hypercarnivory, Binu Shrestha, J. Michael Reed, Philip T. Starks, Gretchen E. Kaufman, Jared V. Goldstone, Melody E. Roelke, Stephen J. O'Brien, Klaus-Peter Koepfli, Laurence Frank, Michael H. Court

Biology Faculty Articles

The domestic cat (Felis catus) shows remarkable sensitivity to the adverse effects of phenolic drugs, including acetaminophen and aspirin, as well as structurally-related toxicants found in the diet and environment. This idiosyncrasy results from pseudogenization of the gene encoding UDP-glucuronosyltransferase (UGT) 1A6, the major species-conserved phenol detoxification enzyme. Here, we established the phylogenetic timing of disruptive UGT1A6 mutations and explored the hypothesis that gene inactivation in cats was enabled by minimal exposure to plant-derived toxicants. Fixation of the UGT1A6 pseudogene was estimated to have occurred between 35 and 11 million years ago with all extant Felidae having dysfunctional …

A Molecular Phylogeny Of Living Primates, Polina L. Perelman, Warren E. Johnson, Christian Roos, Hector Seuanez, Julie E. Horvath, Miguel A. M. Moreira, Bailey Kessing, J. U. Pontius, Melody E. Roelke, Yves Rumpler, Maria P. C. Schneider, Artur Silva, Stephen J. O'Brien, Jill Pecon-Slattery

Biology Faculty Articles

Comparative genomic analyses of primates offer considerable potential to define and understand the processes that mold, shape, and transform the human genome. However, primate taxonomy is both complex and controversial, with marginal unifying consensus of the evolutionary hierarchy of extant primate species. Here we provide new genomic sequence (~8 Mb) from 186 primates representing 61 (~90%) of the described genera, and we include outgroup species from Dermoptera, Scandentia, and Lagomorpha. The resultant phylogeny is exceptionally robust and illuminates events in primate evolution from ancient to recent, clarifying numerous taxonomic controversies and providing new data on human evolution. Ongoing speciation, reticulate …

De Novo Genome Assembly And Snp Marker Development Of Pyrenophora Semeniperda, Marcus Makina Soliai

Theses and Dissertations

Pyrenophora semeniperda (anamorph Drechslera campulata) is a necrotrophic fungal seed pathogen of a variety of grass genra and species, including Bromus tectorum, an exotic grass that has invaded many natural ecosystems of the U.S. Intermountain West. As a natural seed pathogen of B. tectorum, P. semeniperda has potential as a biocontrol agent due to its effectiveness at killing dormant B. tectorum seeds; however, few genetic resources exist for this fungus. Here, the genome assembly of a P. semeniperda isolate using 454 GS-FLX genomic and paired-end pyrosequencing techniques is presented. The total assembly is 32.5 Mb and contains …

Usage And Development Of Molecular Markers For Investigation Of The Population And Ecological Genetics Of Bromus Tectorum L., Keith R. Merrill

Theses and Dissertations

This thesis includes two studies: The first examined patterns of neutral genetic diversity within Bromus tectorum L. across the IMW region, and uses patterns of microsatellite (SSR) genotype distribution to make inferences about the respective roles of adaptively significant genetic variation, adaptive phenotypic plasticity, and facultative outcrossing in the ongoing invasion and recent range expansion of B. tectorum. It has been previously demonstrated that, due to extremely low outcrossing rates, it is possible to characterize individual genotypes of this species using four SSR loci. We sampled 20 individuals from each of 96 B. tectorum populations (classified by region and …

Apparent Competition With Bromus Tectorum Through Pyrenophora Semeniperda Reduces Establishment Of Native Grasses, Katherine Temus Merrill

Theses and Dissertations

Contributing to the success of Bromus tectorum in the Intermountain West may be a mechanism called apparent competition, which occurs when one species increases the pressure of a consumer on a second species. This indirect interaction has been documented only a few times in invasive plant systems, and never in a fungal pathosystem. We examined the effects of the invasive annual Bromus tectorum and predation by the seed pathogen Pyrenophora semeniperda on seedling emergence and survival for two native grasses (Pseudoroegneria spicata and Elymus elymoides), by manipulating B. tectorum densities and P. semeniperda inoculum loads in randomized plots. …

Native Grassland Management Guidelines For Nebraska's Wildlife Management Areas, Gerry Steinauer, Kent Pfeiffer, Jarren Kuipers

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

This document is one of a four part series produced by the Nebraska Game and Parks Commission to provide direction to managers of Wildlife Management Areas (WMAs) in Nebraska. Other documents in the series cover management of woodlands, wetlands, and converted habitats.

Prior to EuroAmerican settlement grasslands covered 98% of the Nebraska landscape and supported the majority of the state’s biodiversity. Since settlement, Nebraska’s native grasslands have suffered serious decline. For example, approximately 98% of eastern Nebraska’s tallgrass prairie has been lost to development. In central and western Nebraska grassland losses have been less dramatic though still substantial. Remnant grasslands …

Native Forest And Woodland Management Guidelines For Nebraska's Wildlife Management Areas, Gerry Steinauer

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

This document is one in a four part series produced by the Nebraska Game and Parks Commission to provide direction to managers of Wildlife Management Areas (WMAs) in Nebraska. Other documents in the series cover management of grasslands, wetlands, and early successional habitats.

Prior to Euroamerican settlement wildfires, drought and competition with prairie grasses limited the presettlement distribution of trees in Nebraska to well-watered and somewhat fire protected river valleys and rocky escarpments. At that time, wooded habitats covered about 2 percent of the Nebraska landscape. Though limited in areal, these communities were diverse and supported important components of Nebraska’s …

Isolation By Distance Explains Genetic Structure Of Buggy Creek Virus, A Bird-Associated Arbovirus, Abinash Padhi, Amy T. Moore, Mary Bomberger Brown, Jerome E. Foster, Martin Pfeffer, Charles R. Brown

School of Natural Resources: Faculty Publications

Many of the arthropod-borne viruses (arboviruses) show extensive genetic variability and are widely distributed over large geographic areas. Understanding how virus genetic structure varies in space may yield insight into how these pathogens are adapted to and dispersed by different hosts or vectors, the relative importance of mutation, drift, or selection in generating genetic variability, and where and when epidemics or epizootics are most likely to occur. However, because most arboviruses tend to be sampled opportunistically and often cannot be isolated in large numbers at a given locale, surprisingly little is known about their spatial genetic structure on the local …
