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 …

Organic Replacement Heifer Enterprise Budget For Walker Dairy, Colton Brodt

Agribusiness

This study was undertaken to determine if Walker Dairy could raise replacement heifers cheaper than the current market price.

The main objective of this report was to calculate how much it costs Walker Dairy to raise a heifer per head. Data collected went into the development of a heifer enterprise budget and determining an average market price. Transfer value in (drop calf price), feed, labor, operating and fixed costs were all factored into the total cost per animal. Also, the data was broken into four different sections of a heifers’ life to aid management in evaluating the cost of raising …

Vocalization Behavior Of The Endangered Bahama Oriole (Icterus Northropi): Ontogenetic, Sexual, Temporal, Duetting Pair, And Geographic Variation, Valerie A. Lee

Faculty Works

Many birds communicate via a diverse set of vocalizations, but the contexts, roles, and structure of their varied songs and calls may change with age, differ between sexes, and vary temporally and geographically. In New World orioles, most tropical species exhibit the ancestral states of sexual monochromatism (both sexes have similar plumage) and monovocalism (both sexes sing and often duet together), whereas migratory temperate species tend toward dichromatism (males brightly colored and females drab) and divocalism (males sing almost exclusively). In this study, I examined the vocalizations of the Bahama Oriole, a non-migratory, monochromatic species, to learn where it fits …

The workshop participants -- experts from academia, regulatory authorities, a scientific animal welfare organization, and the fish vaccine …

Effect Of The Prolactin-Release Inhibitor Quinagolide On Lactating Dairy Cows, P. Lacasse, V. Lollivier, R. Bruckmaier, Y. R. Boisclair, G. F. Wagner, M. Boutinaud

Farm Animal Husbandry Collection

In most mammals, prolactin (PRL) is essential for maintaining lactation, and yet the short-term suppression of PRL during established lactation by bromocriptine has produced inconsistent effects on milk yield in cows and goats. To assess the effect of the long-term inhibition of PRL release in lactating dairy cows, 5 Holstein cows in early lactation received daily intramuscular injections of 1 mg of the PRL-release inhibitor quinagolide for 9 wk. Four control cows received the vehicle (water) only. During the last week of the treatments, one udder half was milked once a day (1×) and the other twice a day …

Assessment Of Pathways For The Introduction And Spread Of Mycobacterium Bovis In The United States, Katie Portacci, Jason Lombard, Lauren Abrahamsen, Eric Bush, Charles Fossler, Robert Harris, Kamina Johnson, Ryan S. Miller, Dianna Mitchell, Randy Pritchard, Steven Sweeney, Todd Weaver

Zoonotics and Wildlife Disease: Publications

Bovine tuberculosis (TB) was responsible for more losses among U.S. farm animals in the early 20th century than all other infectious diseases combined. The Cooperative State-Federal Tuberculosis Eradication Program (established in 1917 and administered by APHIS, State animal health agencies, and U.S. livestock producers) has nearly eradicated bovine TB from the nation’s livestock population. However, despite the many accomplishments of the program, bovine TB remains a serious and costly disease of livestock in the United States. In 1992, VS conducted an assessment to identify pathways for the introduction and spread of bovine TB, in order to develop the most effective …

The Development Of A Novel Technique To Evaluate Binding Between Probiotic Bacteria And Phospholipids, And The Creation Of A Dairy-Based Food Product Rich In Milk Bioactives, Megan Ann Cleveland

Master's Theses

Probiotic bacteria are increasingly prevalent in food and nutritional products today.  These remarkable microorganisms are capable of imparting exceptional health benefits on their host, including prevention of infection by pathogens and stimulation of immune system function.  Their most common mode of delivery is through dairy products (e.g. yogurt), which are also one of their preferred habitats.  The interactions between probiotic bacteria and dairy systems have been studied, but are still not well discerned.  There is a need for better understanding of these associations, as well as those surrounding the mode of bacterial transfer from the food product to the human …

A Late-Season Breeding Record For The Summer Tanager In Nebraska, Eric C. Hopps

Nebraska Bird Review

The breeding range of the Summer Tanager (Piranga rubra) is well documented and expands across the southern U.S. extending northward to New Jersey and west along and south of the Great Lakes to the eastern edge of the Great Plains (Terres 1991; Robinson 1996). In Nebraska the species is generally confined to the Lower Missouri and Platte River Valleys where it occurs locally (Sharpe et al. 2001). Because the species exists in relatively low numbers across southeastern Nebraska, there are few breeding and nesting records for the state. Fewer than 10 breeding records, including one historical account have …

Book Review [Of Wild Birding Colorado: The Big Year Of 2010], W. Ross Silcock

Nebraska Bird Review

Nebraska birders might remember seeing reports posted to NEBirds a few years back by Cole Wild, a native Coloradan whose mother's family is from Nebraska. Cole took up birding at age 19, spurred by an earlier high school environmental science class that required identification of 100 species of birds. As with many of us, a brightly plumaged bird, in this case a Western Tanager, resulted in "the birdwatching gene" in Cole suddenly being "switched to the ON position." Soon after, Cole went on a "what the heck, I'll try it" field trip to see a Kelp Gull at Loveland Reservoir …

2010–2011 Christmas Bird Counts, Don Paseka

Nebraska Bird Review

Fourteen Christmas Bird Counts were held in Nebraska in the 2010–2011 season. The Branched Oak–Seward count was canceled due to weather, but in comparison to last year, the weather was generally dry, mild, and cooperative. Even though open water was limited, the species associated with water were well represented, resulting in the highest total number of species (149) ever, easily topping the previous high count of 138 in 2001. In all, 17 species set new high counts, 5 tied previous highs, and the amazing Brown-headed Nuthatches stayed in Lincoln and were counted for the first time in Nebraska.

Twelve species …

Winter Field Report, December 2010 To February 2011, W. Ross Silcock

Nebraska Bird Review

This winter was pretty much a rerun of last, although perhaps not as severe; I could have used last winter's Introduction again. If there was an overall theme, it would be the widespread occurrences of species that would not be expected to linger into late December and January. Several species of waterbirds, notably Blue-winged Teal, scoters, Ruddy Duck, Common Loon, and Homed and Red-necked Grebes were in this category. Large numbers of Western Grebes were still at Lake McConaughy in early January, and surprisingly late individuals of Black-crowned Night-Heron and Plegadis ibis were located. Mourning Doves were in good numbers …

Book Review [Of The Stokes Field Guide To The Birds Of North America], Tim Hajda

Nebraska Bird Review

Don and Lillian Stokes are well known for their nature guides that cover a variety of subjects, from hummingbirds and beginner shorebird identification to reptiles and amphibians. Their original pair of Stokes Field Guide to Birds: Eastern Region and Western Region have remained popular among North American birders since their appearance in 1995. They were illustrated with photographs instead of the traditional paintings used in most field guides. The authors' latest book, The Stokes Guide to Birds of North America is essentially an entirely new and much improved version of these two guides. Instead of being split into two books, …

Intake, Apparent Digestibility, And Digesta Passage In Leopard Tortoises (Geochelone Pardalis) Fed A Complete, Extruded Feed, Laura Evelyn Lickel

Master's Theses

The influence of feeding juvenile female leopard tortoises (Geochelone pardalis, n=18) a commercially available, complete, extruded feed three (3) or seven days (7) per week on dry matter and digestible energy intake, apparent digestibility of dry matter, organic matter, gross energy and fiber fractions, animal body weight and measurements, digesta transit time, rate of passage, and indigestible fill was evaluated.  Both feeding frequencies are commonly practiced with captive tortoises. When fed 7 compared to 3 days per week, dry matter and digestible energy intake was greater.  Tortoises gained more g BW, but not when adjusted per kg initial …

Characterization Of The Equine Spermadhesin Hsp-7 Found On Stallion Spermatozoa As It Relates To Stallion Fertility And Sperm Capacitation, Melodee Kathleen Heidmiller

Master's Theses

Equine spermadhesin HSP-7 is a 14 kDa protein isolated from stallion seminal plasma and present on the surface of spermatozoa. HSP-7 displays carbohydrate and zona-pellucida binding properties, but the physiological role in equine fertilization is not well defined. HSP-7 has 98% amino acid sequence homology with the well-studied boar spermadhesin, AWN. Currently, these two proteins are considered to have the same reproductive function. Immunofluorescence studies presented here show that the stallion and boar spermadhesins are localized to different segments on spermatozoa. The variation in molecular compartmentalization of spermadhesin molecules in different species suggests that these structurally related proteins could be …

Factors Affecting Space Use Overlap By White-Tailed Deer In An Urban Landscape, W. David Walter, Jeff Beringer, Lonnie P. Hansen, Justin W. Fischer, Joshua J. Millspaugh, Kurt C. Vercauteren

United States Department of Agriculture Wildlife Services: Staff Publications

Variation in the size and overlap of space use by white-tailed deer (Odocoileus virginianus) has broad implications for managing deer–human conflicts and disease spread and transmission in urban landscapes. Understanding which factors affect overlap of home range by various segments (i.e., age, sex) of an urban deer population has implications to direct contact between deer on disease epidemiology. We assessed size of home range and overlap of space use using the volume of intersection index (VI) for deer in an urban landscape by sex, age, season, and time of day. We found mean space use was larger for …

Neuroprotective Effects Of The Lipidic Extract From Integument Of Squid Dosidicus Gigas, Pai-An Hwang, Yi-Gung Tsai, Shu-Yun Gau, Yu-Lan Hung, Chi-Chung Fan

Journal of Marine Science and Technology–Taiwan

The integument of the squid Dosidicus gigas is an industrial waste and trouble the industrial processing. In this study, we examined the lipid composition and neuroprotective effects of D. gigas integument lipidic extract (DGI) in SH-SY5Y neuroblastoma cells which have been exposed to H2O2. The results showed that phospholipids, triacylglycerol and cholesterol accounted for 70.90 ± 4.96 (mean ± S.D.), 20.70 ± 3.54 and 8.40 ± 0.28% of DGI, respectively. And the main fatty acids were docosahexaenoic acid (30.53% of total fatty acid), palmitic acid (20.36% of total fatty acid) and eicosapentaenoic acid (11.84% of total fatty acid). DGI at …
