Occurrence Of The Alien Species Aspidosiphon (Aspidosiphon) Elegans (Sipuncula) On The Levantine And Aegean Coasts Of Turkey, Şermi̇n Açik Jan 2008

Occurrence Of The Alien Species Aspidosiphon (Aspidosiphon) Elegans (Sipuncula) On The Levantine And Aegean Coasts Of Turkey, Şermi̇n Açik

Turkish Journal of Zoology

A total of 37 specimens of Aspidosiphon (Aspidosiphon) elegans were collected at 5 stations located along the Levantine coast of Turkey and at 1 station located near Foça (Aegean Sea). This species inhabited calcareous rocks, the mussel Branchidontes pharaonis, and the alga Corallina mediterranea between 0 and 3 m depths. The population density of this species in the area was found to be 25 ind. M^{-2}. As Aspidosiphon (A.) elegans is a bio-eroder species, its high population density may cause serious damage to coralligenous habitats. This study gives more data regarding the morphological, biological, and ecological features of the species …

Out Of South America: Multiple Origins Of Non-Native Apple Snails In Asia, Kenneth Hayes Jan 2008

Out Of South America: Multiple Origins Of Non-Native Apple Snails In Asia, Kenneth Hayes

Department of Biology Faculty Publications

Apple snails (Ampullariidae: Pomacea) native to the New World have become agricultural and environmental pests widely in southern and eastern Asia since their introduction in about 1980. Although their impacts have been extensively documented, considerable confusion persists regarding their identities and geographical origins. Efforts to resolve the confusion have suffered from inadequate taxonomic and geographical sampling from both native and introduced ranges. Using phylogenetic and genealogical methods, we analysed 610–655 bp of cytochrome c oxidase subunit I DNA sequences from 783 apple snails from 164 Asian locations and 57 native South American locations. In Asia, we found four species of …

Determination Of Diet Protein And Digestibility Of Native Sandhills Upland Range, Bobbi Gene Geisert, Terry J. Klopfenstein, Don C. Adams, Jacqueline A. Musgrave, Walter H. Schacht Jan 2008

Determination Of Diet Protein And Digestibility Of Native Sandhills Upland Range, Bobbi Gene Geisert, Terry J. Klopfenstein, Don C. Adams, Jacqueline A. Musgrave, Walter H. Schacht

Nebraska Beef Cattle Reports

A significant year by grazing level effect was detected on CP content of diet samples collected from 2003 to 2005 at the Gudmundsen Sandhills Laboratory. During drought years (2003 and 2004) cows selected plants which were higher in CP and lower in digestibility. High levels of grazing pressure decreased diet IVOMD compared to diets from ungrazed and moderately grazed pastures. Prediction models generated from these data predict dietary CP and organic matter disappearance (OMD) of cattle grazing native Sandhills range pastures.

The Effects Of Supplementing Wet Distillers Grains Mixed With Wheat Straw To Growing Steers, Brandon L. Nuttelman, Terry J. Klopfenstein, William A. Griffin, Matt K. Luebbe Jan 2008

The Effects Of Supplementing Wet Distillers Grains Mixed With Wheat Straw To Growing Steers, Brandon L. Nuttelman, Terry J. Klopfenstein, William A. Griffin, Matt K. Luebbe

Nebraska Beef Cattle Reports

A growing study compared feeding wet distillers grains, dried distillers grains, and a mix of 66% wet distillers grains and 33% wheat straw as supplements to a forage-based diet. Steers were supplemented 0, 2, 4, or 6 lb distillers grains/head daily. Wet distillers grains and dried distillers grains produced higher final body weight and dry matter intake compared to the mix. Increasing levels of distillers grains increased performance in forage based diets and wet grains mixed with straw reduced forage intake.

Influence Of Corn Hybrid And Processing Method On Finishing Performance And Carcass Characteristics, Flint W. Harrelson, Matt K. Luebbe, Galen E. Erickson, Terry J. Klopfenstein, Wayne A. Fithian Jan 2008

Influence Of Corn Hybrid And Processing Method On Finishing Performance And Carcass Characteristics, Flint W. Harrelson, Matt K. Luebbe, Galen E. Erickson, Terry J. Klopfenstein, Wayne A. Fithian

Nebraska Beef Cattle Reports

Five commercially available corn hybrids were evaluated for finishing cattle performance and carcass characteristics when fed as high-moisture (HMC) or dry-rolled corn (DRC). No significant interactions were observed between hybrid and processing method. Corn hybrid had no significant impact on ADG or DMI, but did have a minor influence on F:G. However, these data suggested that processing as HMC-method had a greater effect on cattle performance than hybrid.

Influence Of Corn Hybrid And Processing Method On Ruminal And Intestinal Digestion, Flint W. Harrelson, Nathan F. Meyer, Galen E. Erickson, Terry J. Klopfenstein, Wayne A. Fithian Jan 2008

Influence Of Corn Hybrid And Processing Method On Ruminal And Intestinal Digestion, Flint W. Harrelson, Nathan F. Meyer, Galen E. Erickson, Terry J. Klopfenstein, Wayne A. Fithian

Nebraska Beef Cattle Reports

Using the mobile bag technique, five commercially available corn hybrids harvested as either dry-rolled or high-moisture corn were evaluated for site and extent of DM and starch digestion. Total-tract DM digestibility was improved 7 to 16 percentage units, and total-tract starch digestibility was improved 9 to 18 percentage units among hybrids when processed as high-moisture corn compared to dry-rolled corn. The results of this trial suggest that hybrid and processing method interact and can influence DM and starch digestibility.

Modeling Daily Water Intake In Cattle Finished In Feedlots, Rodrigo A. Arias, Terry L. Mader Jan 2008

Modeling Daily Water Intake In Cattle Finished In Feedlots, Rodrigo A. Arias, Terry L. Mader

Nebraska Beef Cattle Reports

Simple regression and multiple regression analyses were conducted to estimate factors affecting daily water intake(DWI) of finishing cattle. Seasonal simple linear regression equations were very poor predicting DWI (r2 < 0.15). Best results were obtained with the overall simple regression. The multiple regression analysis showed that daily minimum temperature (or THI), solar radiation, and dry matter intake were the most important factors affecting DWI in cattle finished in feedyards. The following prediction equation was developed: daily water intake, gal*d-1 = -0.52677+ (0.1229 *DMI, lb*d-1) + (0.01137*solar radiation, kcal*d-1) + (0.06529*daily minimum temperature, °F).

The Effect Of Delaying Initial Feedlot Implant On Performance And Carcass Characteristics Of Calf-Fed Steers, William A. Griffin, Don C. Adams, Richard N. Funston Jan 2008

The Effect Of Delaying Initial Feedlot Implant On Performance And Carcass Characteristics Of Calf-Fed Steers, William A. Griffin, Don C. Adams, Richard N. Funston

Nebraska Beef Cattle Reports

Steers in two, 2-year experiments (n = 409) were either given an implant at feedlot arrival or implanted 30 days after feedlot entry. In Experiment 1, steer calves were not implanted at branding and in Experiment 2 calves were implanted at branding. There was no difference in feedlot performance for either experiment. However, in Experiment 1 there was a year by treatment interaction for marbling score suggesting that delaying implant in calves may affect quality grade.

Nebraska Beef Cattle Reports

In a clinical trial where cattle were either given Excede® or not on arrival, ADG increased and F:G was numerically improved for cattle that received Excede compared to control cattle. There were no differences between initial or final BW, or DMI observed during the receiving period due to the administration of Excede. The incidence of bovine respiratory disease (BRD) for the 32 days of the study was 4.4% for cattle that received Excede at arrival and was different compared to the control cattle which was 12.2%. The correlation (-0.157) between DMI and morbidity observed in this study was not significant. …

Effects Of Aging On Veal Shoulder Muscles, Gary A. Sullivan, Chris R. Calkins, D. Dwain Johnson, Brian G. Sapp Jan 2008

Effects Of Aging On Veal Shoulder Muscles, Gary A. Sullivan, Chris R. Calkins, D. Dwain Johnson, Brian G. Sapp

Nebraska Beef Cattle Reports

Six muscles were attained from 36 paired veal shoulders and each pair was assigned to one of six aging comparisons. After aging, muscles were cooked and evaluated using Warmer Bratzler shear force. The largest decline in shear force occurred during comparison of 3 and 10 days aging with additional improvements found up to 24 days. The m. infraspinatus was the most tender muscle; the m. supraspinatus was the toughest. The m. serratus ventralis had the greatest response to aging and the m. pectoralis profundus (brisket) had the least.

Relationship Between Metabolizable Protein Balance And Feed Efficiency Of Steers And Heifers, Grant I. Crawford, Stephanie A. Quinn, Terry J. Klopfenstein, Galen E. Erickson

Nebraska Beef Cattle Reports

Two individual feeding experiments were analyzed for the relationship between metabolizable protein (MP) balance and feed efficiency (G:F) in individually-fed steers and heifers. In Experiment 1, 29 crossbred steers were fed steam-flaked corn (SFC)-based diets containing either 0% or 1.2% urea (DM basis). In Experiment 2, 75 crossbred heifers were fed SFC-based diets with either 0% or 1.5% urea. The NRC (1996) MP model was used to determine individual degradable intake protein and MP balances. In both experiments there was a negative relationship within treatment between MP balance and G:F. These results were not expected, and three potential causes were …

Engineer Cantonment, Missouri Territory, 1819-1820: America's First Biodiversity Ineventory, Hugh H. Genoways, Brett C. Ratcliffe

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

It is our thesis that members of the Stephen Long Expedition of 1819-20 completed the first biodiversity inventory undertaken in the United States at their winter quarters, Engineer Cantonment, Missouri Territory, in the modern state of Nebraska. This accomplishment has been overlooked both by biologists and historians, but it should rank among the most significant accomplishments of the expedition. The results of this inventory allow us to evaluate the environmental, faunal, and floral changes along the Missouri River in the intervening nearly 190 years. The historical records form a visual image of a dynamic riverine system in which a highly …

Historic And Recent Distributions Of Elk In Nebraska, Kent A. Fricke, Michael A. Cover, Scott E. Hygnstrom, Scott R. Groepper, Hugh H. Genoways, Kit M. Hams, Kurt C. Vercauteren Jan 2008

Historic And Recent Distributions Of Elk In Nebraska, Kent A. Fricke, Michael A. Cover, Scott E. Hygnstrom, Scott R. Groepper, Hugh H. Genoways, Kit M. Hams, Kurt C. Vercauteren

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

Elk (Cervus elaphus) were historically found throughout North America but were extirpated from Nebraska and much of the Great Plains in the 1880s due to consumptive uses by settlers, miners, market hunters, and others. Elk began to reappear in Nebraska in the 1950s and 1960s, and established a stable, nonmigratory population that currently consists of seven herds and an estimated 1,400 individuals throughout western and central Nebraska. The reappearance and subsequent persistence of elk in Nebraska suggests there is adequate habitat to support a self-sustaining population. The general movement of elk eastward may lead to an eventual statewide …

Distribution Patterns And Habitat Use Of Black Cockatoos (Calyptorhynchus Spp.) In Modified Landscapes In The South-West Of Western Australia, Marieke S. Weerheim Jan 2008

Distribution Patterns And Habitat Use Of Black Cockatoos (Calyptorhynchus Spp.) In Modified Landscapes In The South-West Of Western Australia, Marieke S. Weerheim

Theses: Doctorates and Masters

Conservation planning for animal species inhabiting modified landscapes requires understanding of where animals occur and how they utilise both natural and modified habitats. In this study the distribution and foraging behaviour of the forest red-tailed cockatoo (Calyptorhynchus banksii naso), Baudin’s cockatoo (C. baudinii) and Carnaby’s cockatoo (C. latirostris) was investigated in three study areas which each contained a different combination of modified habitats. Pickering Brook contained native forest and orchards, Wungong contained a mosaic of native forest and revegetation, while Karnet contained primarily native forest and paddocks. The relationship between cockatoo distribution and land use types was examined by constructing …

Ecological Factors Determining Nesting Habitat For American Avocets, Landon R. Jones Jan 2008

Ecological Factors Determining Nesting Habitat For American Avocets, Landon R. Jones

Student Works

The American Avocet (Recurvirostra americana) is a large shorebird that breeds and congregates in open, shallow, saline wetlands (Robinson et al. 1997). Its long, curved bill is well adapted for stirring up and feeding on invertebrates from the benthos. Because they fill such a narrow habitat niche, the majority of avocets concentrate in the thousands to breed in a few hot spots such as Mono Lake in California, and the Great Salt Lake in Utah (Robinson et al. 1997). Avocets arrive at the Great Salt Lake in late March and nest from mid-April to mid-July (Sordahl 1981). They require 15-20 …

Sharpshooting Suburban White-Tailed Deer Reduces Deer–Vehicle Collisions, Anthony J. Denicola, Scott C. Williams Jan 2008

Sharpshooting Suburban White-Tailed Deer Reduces Deer–Vehicle Collisions, Anthony J. Denicola, Scott C. Williams

Human–Wildlife Interactions

Too many deer–vehicle collisions (DVCs) are one of the primary reasons local governments implement lethal deer management programs. However, there are limited data to demonstrate that a reduction in deer (Odocoileus spp.) densities will result in a decline in DVCs. We conducted sharpshooting programs in 3 suburban communities to reduce deer numbers and to address rising DVCs. Annual or periodic population estimates were conducted using both helicopter snow counts and aerial infrared counts to assess population trends. Management efforts were conducted from 3 to 7 years. Local deer herds were reduced by 54%, 72%, and 76%, with resulting reductions …

Physiological Effects Of Gonadotropin-Releasing Hormone Immunocontraception On White-Tailed Deer, Paul D. Curtis, Milo E. Richmond, Lowell A. Miller, Fred W. Quimby Jan 2008

Physiological Effects Of Gonadotropin-Releasing Hormone Immunocontraception On White-Tailed Deer, Paul D. Curtis, Milo E. Richmond, Lowell A. Miller, Fred W. Quimby

Human–Wildlife Interactions

Before immunocontraceptives can be considered safe to use on wildlife species, potential health risks should be assessed. Gonadotropin-releasing hormone (GnRH) immunocontraceptive has successfully reduced fertility of white-tailed deer (Odocoileus virginianus); however, associated deer physiology has rarely been examined. We conducted gross necropsy examinations, histology, and blood chemistry comparisons on euthanized deer previously vaccinated with immunogenic GnRH (n = 18 females and n = 4 males), or left as untreated controls (n = 7 females and n = 6 males). Granulomas were found at injection sites of most deer, even 3 years post-treatment. There were no significant …
