Optimal Body Size With Respect To Maximal Speed For The Yellow-Spotted Monitor Lizard (Varanus Panoptes; Varanidae), Christofer J. Clemente, Philip C. Withers, Graham Thompson Jan 2012

Optimal Body Size With Respect To Maximal Speed For The Yellow-Spotted Monitor Lizard (Varanus Panoptes; Varanidae), Christofer J. Clemente, Philip C. Withers, Graham Thompson

Research outputs 2012

Studies of locomotor performance often link variation in morphology with ecology. While maximum sprint speed is a commonly used performance variable, the absolute limits for this performance trait are not completely understood. Absolute maximal speed has often been shown to increase linearly with body size, but several comparative studies covering a large range of body sizes suggest that maximal speed does not increase indefinitely with body mass but rather reaches an optimum after which speed declines. Because of the comparative nature of these studies, it is difficult to determine whether this decrease is due to biomechanical constraints on maximal speed …

Impacts Of Urbanisation On The Native Avifauna Of Perth, Western Australia, Robert Davis, C Gole, Jd Roberts Jan 2012

Impacts Of Urbanisation On The Native Avifauna Of Perth, Western Australia, Robert Davis, C Gole, Jd Roberts

Research outputs 2012

Urban development either eliminates, or severely fragments, native vegetation, and therefore alters the distribution and abundance of species that depend on it for habitat. We assessed the impact of urban development on bird communities at 121 sites in and around Perth, Western Australia. Based on data from community surveys, at least 83 % of 65 landbirds were found to be dependent, in some way, on the presence of native vegetation. For three groups of species defined by specific patterns of habitat use (bushland birds), there were sufficient data to show that species occurrences declined as the landscape changed from variegated …

Minimum Cost Of Transport In Asian Elephants: Do We Really Need A Bigger Elephant?, V. A. Langman, M. F. Rowe, T. J. Roberts, N. V. Langman, C. R. Taylor Jan 2012

Minimum Cost Of Transport In Asian Elephants: Do We Really Need A Bigger Elephant?, V. A. Langman, M. F. Rowe, T. J. Roberts, N. V. Langman, C. R. Taylor

Dartmouth Scholarship

Body mass is the primary determinant of an animal’s energy requirements. At their optimum walking speed, large animals have lower mass-specific energy requirements for locomotion than small ones. In animals ranging in size from 0.8 g (roach) to 260 kg (zebu steer), the minimum cost of transport (COTmin) decreases with increasing body size roughly as COTmin∝body mass (Mb)–0.316±0.023 (95% CI). Typically, the variation of COTmin with body mass is weaker at the intraspecific level as a result of physiological and geometric similarity within closely related species. The interspecific relationship estimates that …

The Influence Of Selenium Status On Immune Function And Antioxidant Status In The Horse, Mieke Brummer Jan 2012

The Influence Of Selenium Status On Immune Function And Antioxidant Status In The Horse, Mieke Brummer

Theses and Dissertations--Animal and Food Sciences

Selenium (Se) has received a lot of attention for its antioxidant and immune modulating properties. Yet, comparably few studies have focused on the horse. Therefore the objectives of this research were to evaluate the influences of Se status on immune function and antioxidant defense in horses. Twenty eight horses were allocated to one of 4 dietary Se treatments: low (LS), adequate (AS), high organic (SP) and high inorganic (SS). First, horses assigned to LS, SP and SS were depleted of Se and received a low Se diet (0.07 ppm Se) for 35 wk, while AS received an adequate Se diet …

Geostatistical Spatiotemporal Modelling With Application To The Western King Prawn Of The Shark Bay Managed Prawn Fishery, Ainslie M. Denham Jan 2012

Geostatistical Spatiotemporal Modelling With Application To The Western King Prawn Of The Shark Bay Managed Prawn Fishery, Ainslie M. Denham

Theses: Doctorates and Masters

Geostatistical methodology has been employed in the modelling of spatiotemporal data from various scientific fields by viewing the data as realisations of space-time random functions. Traditional geostatistics aims to model the spatial variability of a process so, in order to incorporate a time dimension into a geostatistical model, the fundamental differences between the space and time dimensions must be acknowledged and addressed. The main conceptual viewpoint of geostatistical spatiotemporal modelling identified within the literature views the process as a single random function model utilising a joint space-time covariance function to model the spatiotemporal continuity. Geostatistical space-time modelling has been primarily …

Birth Timing For Mountain Lions (Puma Concolor); Testing The Prey Availability Hypothesis, Brian D. Jansen Jan 2012

Birth Timing For Mountain Lions (Puma Concolor); Testing The Prey Availability Hypothesis, Brian D. Jansen

Natural Resource Management Faculty Publications

We investigated potential advantages in birth timing for mountain lion (Puma concolor) cubs. We examined cub body mass, survival, and age of natal dispersal in relation to specific timing of birth. We also investigated the role of maternal age relative to timing of births. We captured mountain lion cubs while in the natal den to determine birth date, which allowed for precise estimates of the population birth pulse and age of natal dispersal. A birth pulse occurred during June–August. Body mass of cubs was related to litter size and timing of birth; heaviest cubs occurred in litters of 2, and …

Priority Effects Among Young-Of-The-Year Fish: Reduced Growth Of Bluegill Sunfish (Lepomis Macrochirus) Caused By Yellow Perch (Perca Flavescens)?, Mark A. Kaemingk, Jeffrey C. Jolley, David W. Willis, Steven R. Chipps Jan 2012

Priority Effects Among Young-Of-The-Year Fish: Reduced Growth Of Bluegill Sunfish (Lepomis Macrochirus) Caused By Yellow Perch (Perca Flavescens)?, Mark A. Kaemingk, Jeffrey C. Jolley, David W. Willis, Steven R. Chipps

Natural Resource Management Faculty Publications

1. When available, Daphnia spp. are often preferred by age-0 yellow perch and bluegill sunfish because of energetic profitability. We hypothesised that predation by age-0 yellow perch could lead to a midsummer decline (MSD) of Daphnia spp. and that priority effects may favour yellow perch because they hatch before bluegill, allowing them to capitalise on Daphnia spp. prior to bluegill emergence. 2. Data were collected from 2004 to 2010 in Pelican Lake, Nebraska, U.S.A. The lake experienced a prolonged MSD in all but 1 year (2005), generally occurring within the first 2 weeks of June except in 2008 and 2010 …

The Rise And Fall Of Crassostrea Virginica Oyster Reefs: The Role Of Disease And Fishing In Their Demise And A Vignette On Their Management, Eric N. Powell, John M. Klinck, Kathryn Ashton-Alcox, Eileen E. Hofmann, Jason Morson

CCPO Publications

We describe a model designed to simulate the shell carbonate budget of an oyster reef.We identify five parameters descriptive of basic characteristics of the shell carbonate budget of a reef that limit simulation accuracy. Two describe the TAZ (taphonomically-active zone) and the distribution of shell carbonate within it. One is the taphonomic rate in the TAZ. Two determine the volume contribution of shell carbonate and the taphonomic loss rate within the reef framework. For Mid-Atlantic estuaries, model simulations suggest that reef accretion only occurs if oyster abundance is near carrying capacity. Simulations further suggest that reef accretion is infeasible for …

Repeatability Of Prolactin Responses To Sulpiride In Mares And Geldings And The Effect Of Pergolide And Cabergoline, Rebekah C. Hebert Jan 2012

Repeatability Of Prolactin Responses To Sulpiride In Mares And Geldings And The Effect Of Pergolide And Cabergoline, Rebekah C. Hebert

LSU Master's Theses

Four experiments were conducted in an effort to develop a method, based on prolactin secretion, for assessing the efficacy and duration of activity of dopaminergic agonists for the treatment of pituitary pars intermedia dysfunction (PPID) in horses. In the first experiment, prolactin response to a low dose of the dopamine antagonist, sulpiride, was generally repeatable in estrogen-primed geldings in winter over 8 every-other-day challenges. It was concluded that estrogen-primed, sulpiride-challenged geldings in winter could serve as a model for the study of potential dopaminergic drugs for the treatment of PPID in horses. The second experiment was performed in the summer …

Lentiviral Transduction Of Epigenetically Modified Bovine Adult Stem Cells, Meredith Kathleen Addison Jan 2012

Lentiviral Transduction Of Epigenetically Modified Bovine Adult Stem Cells, Meredith Kathleen Addison

LSU Master's Theses

Bovine adipose-derived stem cells (ADS), a form of adult stem cells, are somatic cells that have similar characteristics of embryonic stem (ES) cells. Bovine ADS cells possess multipotent capabilities and have been found to express pluripotency genes associated with ES cells. The unique properties of ADS cells make them a desirable source for reprogramming experiments. The goal of reprogramming experiments is to transform somatic cells from a differentiated state to a pluripotent state. When somatic cells reprogram, there are certain epigenetic changes or modifications that must occur in order to successfully reprogram the nucleus. Epigenetic modifications will change the chromatin …

Influence Of Weaning Date And Prepartum Nutrition On Cow-Calf Productivity, Kelsey M. Rolfe, L. Aaron Stalker, Terry J. Klopfenstein Klopfenstein, Richard N. Funston

Nebraska Beef Cattle Reports

October weaned cows had greater average BCS and BW compared to December weaned cows; however, the level of supplementation on winter range did not impact BCS or BW. Subsequent pregnancy rates (96.5% - 98.5%) were not influenced by weaning date or any winter treatments. Steer progeny showed no differences in feedlot entry BW, final BW, DMI, ADG, or carcass characteristics; and there were no differences in percentage cycling before breeding or in pregnancy rates of heifer progeny.

Oocyte Mrna And Follicle Androgen Levels Associated With Fertility, Ningxia Lu, Jacqueline Smith, Vanessa Brauer Brauer, Adam Summers, William E. Pohlmeier, Kevin A. Beavers, Renee M. Mcfee, Kevin Sargent, Jill Kerl, Robert A. Cushman, Andrea S. Cupp, Jennifer R. Wood

Nebraska Beef Cattle Reports

The environment that the oocyte develops in (follicle) and the mRNA that is produced (mRNA abundance) during development were examined. Androgen levels within the follicle were higher in heifers (≤ 2 years) that never established a pregnancy compared to cows that stayed in the herd at least 3 years and had at least one successful pregnancy. These high androgen levels were associated with increased abundance of several candidate mRNAs in the cumulus-oocyte complex (COC), which includes the oocyte and somatic cells immediately surrounding the oocyte, isolated from the dominant follicle. The data suggest that androgen levels represent a marker for …

Economic Analysis Of Keeping A Nonpregnant Cow, Trenton Bohling, Darrell R. Mark, Richard Rasby, David R. Smith Jan 2012

Economic Analysis Of Keeping A Nonpregnant Cow, Trenton Bohling, Darrell R. Mark, Richard Rasby, David R. Smith

Nebraska Beef Cattle Reports

Abnormally large numbers of nonpregnant cows in cow-calf herds may be caused by diseases like trichomoniasis or a culmination of environmental factors such as heat stress during breeding and abnormally cold winters and wet spring conditions. Typically, producers sell nonpregnant females and replace them with bred heifers or cows. The five-year cash flow budgets developed in this study suggest that in some circumstances it is economically feasible to keep a nonpregnant cow.

Spoilage Of Wet Distillers Grains Plus Solubles And Feed Value, Jana L. Harding, Kelsey M. Rolfe, Cody J. Schneider Schneider, Brandon L. Nuttelman, Galen E. Erickson, Terry J. Klopfenstein Jan 2012

Spoilage Of Wet Distillers Grains Plus Solubles And Feed Value, Jana L. Harding, Kelsey M. Rolfe, Cody J. Schneider Schneider, Brandon L. Nuttelman, Galen E. Erickson, Terry J. Klopfenstein

Nebraska Beef Cattle Reports

Performance of growing or finishing steers fed wet distillers grains plus solubles (WDGS) from a silo bag (nonspoiled) or bunker (spoiled) was studied. Spoiled WDGS lost DM, as well as decreased in fat, NDF, and CP. Even though DM was lost, and composition of the spoiled WDGS changed, the spoiled WDGS had no effect on finishing cattle performance, but it did affect DMI of the growing steers consuming high forage diets.

Metabolism Of Finishing Diets Containing Condensed Distillers Solubles And Wdgs, Anna C. Pesta, Adam L. Shreck, Terry J. Klopfenstein Klopfenstein, Galen E. Erickson Jan 2012

Metabolism Of Finishing Diets Containing Condensed Distillers Solubles And Wdgs, Anna C. Pesta, Adam L. Shreck, Terry J. Klopfenstein Klopfenstein, Galen E. Erickson

Nebraska Beef Cattle Reports

A metabolism study was conducted to evaluate the effects of feeding wet distillers grains (WDGS) and condensed distillers solubles (CDS), both separately and in combination, on the metabolism characteristics of feedlot steers. Diet had no impact on nutrient digestibility. Average ruminal pH was lower for steers fed CDS than for those fed WDGS alone, and steers fed WDGS spent less time below pH 5.6 than steers fed diets with no WDGS. Inclusion of CDS decreased ruminal acetate concentration and acetate to propionate ratio compared to diets with less or no CDS.
