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 …

The Secretive Shorebirds: Nebraska’S Phantom Migrants, Paul A. Johnsgard

Paul Johnsgard Collection

Much less apparent and well known than the annual crane migration is Nebraska’s role in the spring and fall migrations of shorebirds such as sandpipers, plovers, curlews and godwits. These migrations are inconspicuous, in part because of the fact that most long-distance shorebird flights occur at night. Shorebirds also never migrate in the enormous flocks that are so typical of geese and cranes, and their flights are usually unaccompanied by loud calls. Yet, they are massive if nearly invisible migrations, involving over 30 species and an estimated 200,000–300,000 birds. Many of the species travel from South American wintering grounds, and …

Quantifying Recreational Fishing Catch And Effort: A Pilot Study Of Shore-Based Fishers In The Perth Metropolitan Area, Claire B. Smallwood, K H. Pollock, Brent S. Wise, Norman G. Hall, Daniel J. Gaughan

Fisheries research reports

Recreational fishing is a popular activity throughout Western Australia, including adjacent to the populous Perth Metropolitan area. Understanding the level of catch and effort associated with this activity is essential for the sustainable management of fish stocks. Whilst the focus of recent surveys in the Perth Metropolitan area has been on boat-based fishers targeting demersal species, shore-based fishing has not been measured for many years. Recent changes to management controls for these demersal species, including the implementation of a fishing boat licence, may increase existing pressures on nearshore stocks by displacing fishing effort onto these resources. Therefore, a need exists …

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

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 …

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 …

Nitric Oxide Synthesis By Chicken Macrophages Results In Coordinated Changes Of Multiple Arginine Transporters, Michael Moulds

Master's Theses

Arginine transport is primarily mediated by the cationic amino acid transporters (CATs) in mammalian cells, but in aves the y⁺, b^0,+ and B^0,+ transport systems have also been observed. Arginine is the limiting catabolic substrate required for the production of nitric oxide (NO), a highly reactive compound that acts as a signaling molecule or killing compound. NO is synthesized by inducible nitric oxide synthase (iNOS) by macrophages for pathogen clearance. In mammals, CAT-2B is responsible for ARG import in the macrophage for NO synthesis, but the chicken CAT-2B isoform does not transport ARG. Therefore the objective …

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

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 …

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

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 …

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

Great Plains Research: A Journal of Natural and Social Sciences

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 …

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

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

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 …

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 …

Predators Of Enashiva: A Survey Of Occurrence & Distribution, Adrienne Fisk Bowles

Independent Study Project (ISP) Collection

This study was conducted during a period of 16 days (April 10 to April 26, 2011) at the Enashiva Nature Refuge in Northern Tanzania. It was a modified repeat study, using the same methodologies of a mammal survey conducted in November 2009, however this study only focused on occurrence and distribution of predators in the highest trophic level and accounted for reptile and birds, in addition to mammals. Based upon the findings of the November 2009 study, it was hypothesized that the woodland would have the highest predator species richness. This hypothesis was supported by the data; the woodland habitat …

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 …
