Response Of Large River Fishes To A Prolonged High Water Event In The Missouri River, Nebraska, Nicholas Paul Hogberg 2014 University of Nebraska - Lincoln

Response Of Large River Fishes To A Prolonged High Water Event In The Missouri River, Nebraska, Nicholas Paul Hogberg

Dissertations & Theses in Natural Resources

Regulation and modification of large rivers to accommodate human uses have been a root cause of freshwater biodiversity declines. The Missouri River is among the most drastically-altered large river systems in North America, with a series of mainstem impoundments in the upper watershed altering flow characteristics downstream, and channelization throughout the lower river homogenizing instream habitat and reducing off-channel habitat. Precipitation events during the winter and spring 2010-2011 caused flooding of the greatest magnitude and duration since reservoir completion. The large magnitude and long duration of this flood made it unlike any flood in recent history and provided a unique ...


Accuracy Or Precision: Implications Of Sample Design And Methodology On Abundance Estimation, Lucas K. Kowalewski 2014 University of Nebraska - Lincoln

Accuracy Or Precision: Implications Of Sample Design And Methodology On Abundance Estimation, Lucas K. Kowalewski

Dissertations & Theses in Natural Resources

Estimation of population size by spatially replicated counts (point-count method) has been used for many large-scale animal-monitoring programs, yet its application in aquatic environments has been limited. Multiple site-specific estimates of abundance can be averaged and combined with covariate data to predict total abundance across an area of interest. Covariate data also provide an understanding of the relationship between abundance and habitat use, which is a fundamental interest of many animal-population investigations. Design of sampling scenarios for point-count population-estimate surveys can influence the accuracy and precision of the population estimate. The first objective of this study was to examine how ...


Nutrient Utilization, Lactational Performance, And Profitability Of Dairy Cows By Feeding Protein Supplements In High-Forage Lactation Diets, Kathryn Neal 2014 Utah State University

Nutrient Utilization, Lactational Performance, And Profitability Of Dairy Cows By Feeding Protein Supplements In High-Forage Lactation Diets, Kathryn Neal

All Graduate Theses and Dissertations

Due to the increasing cost of soybean meal and concerns of excess N being excreted into the environment, new protein supplements have been developed. Two products that have shown potential in increasing N utilization efficiency are slow release urea (SRU; Optigen) and ruminal escape protein derived from yeast (YMP; DEMP). The objective of this study was to assess the effects of feeding these 2 supplements in high-forage [(54% of total dietary dry matter (DM)] dairy diets on nutrient utilization, feed efficiency, lactational performance of dairy cows, and their impacts on income-over feed costs. Twelve multiparous dairy cows were used in ...

Northern Saw-Whet Owls: A Descriptive Look At Their Anatomy, Behavior, And Migration, Brandon M. Ray 2014 Liberty University

Northern Saw-Whet Owls: A Descriptive Look At Their Anatomy, Behavior, And Migration, Brandon M. Ray

Senior Honors Theses

The Northern Saw-whet Owl (Aegolius acadicus) is a small species of migratory owl native to North America. Through an analysis of research conducted at Liberty University’s Camp Hydaway in the Piedmont of Virginia as well as comparison studies at owl netting stations in the mountains and the coastal plain, it was shown that the Northern Saw-whet migrates along consistent routes southward while the timing and frequency of the migration varies by several days based on sex, age, owl population fluctuations, weather, and the owls’ physical health. Several years’ worth of owl capture data were compiled from stations across Virginia ...

Analytical Methods For Chemical And Sensory Characterization Of Scent-Markings In Large Wild Mammals: A Review, Simone B. Soso, Jacek A. Koziel, Anna K. Johnson, Young Jin Lee, W. Sue Fairbanks

Agricultural and Biosystems Engineering Publications and Papers

In conjoining the disciplines of “ethology” and “chemistry” the field of “Ethochemistry” has been instituted. Ethochemistry is an effective tool in conservation efforts of endangered species and the understanding of behavioral patterns across all species. Chemical constituents of scent-markings have an important, yet poorly understood function in territoriality, reproduction, dominance, and impact on evolutionary biology, especially in large mammals. Particular attention has recently been focused on scent-marking analysis of great cats (Kalahari leopards (Panthera pardus), puma (Puma concolor) snow leopard (Panthera uncia), African lions (Panthera leo), cheetahs (Acinonyx jubatus), and tigers (Panthera tigris)) for the purpose of conservation. Sensory analyses ...

The objectives of this study were to 1) determine the conditions (temperature and pH) that exist in early postmortem muscle of normally chilled and delay chilled beef carcasses to provide a model for in vitro work and 2) determine the mechanism by which early postmortem temperature/pH conditions found in beef muscle influence the enzymes that regulate the aging process in vitro. For objective 1, 7 finished beef animals (HCW 385 ± 8 kg) were harvested with the right sides subjected to normal chilling (2.3°C) approximately 1.25 h postmortem and the left sides subjected to ambient temperature (delay ...


Effects Of Prey Abundance On Breeding Season Diet Of Northern Goshawks (Accipiter Gentilis) Within An Unusual Prey Landscape, Robert A. Miller, Jay D. Carlisle, Marc J. Bechard 2014 Boise State University

Effects Of Prey Abundance On Breeding Season Diet Of Northern Goshawks (Accipiter Gentilis) Within An Unusual Prey Landscape, Robert A. Miller, Jay D. Carlisle, Marc J. Bechard

Idaho Bird Observatory Publications and Presentations

A critical element of diet analysis is species adaptability to alternative prey sources. The breeding-season diet of Northern Goshawks (Accipiter gentilis) includes both mammalian and avian species, varies geographically, and is often dependent upon tree squirrels of the genera Sciurus andTamiasciurus. We studied alternative prey sources of Northern Goshawks in the South Hills of south-central Idaho, an area where tree squirrels are naturally absent and other prey frequently important in the diet of goshawks, such as smaller corvids, are uncommon. We quantified the diet of goshawks using nest cameras and surveyed abundance of prey using line transects. We found ...


The Effects Of Substituting True Protein With Non-Protein Nitrogen In Holstein Dairy Heifers Precision-Fed Different Forage To Concentrate Ratios, Noe Alberto Gomez 2014 California Polytechnic State University

The Effects Of Substituting True Protein With Non-Protein Nitrogen In Holstein Dairy Heifers Precision-Fed Different Forage To Concentrate Ratios, Noe Alberto Gomez

Animal Science

Understanding the efficiency and digestibility of dietary nutrients in dairy heifers is essential for minimizing costs and environmental impacts of the dairy industry. The objective of this study was to interpret the effects of manipulating rumen-degradable protein (RDP) in a precision feeding system. Eight Holstein ruminally cannulated heifers (14.6 ± 0.1 mo of age, and 386 ± 9.1 kg of weight) were randomly assigned to 2 forage levels: HC (25% forage) and LC (75% forage) and to a degradable protein sequence [0% degradable protein from urea U, 100% casein C (no urea treatment U0); 33% U, 67% C (low ...

These photographs describe “Science” born of consumerism, hijacked by me, economically disenfranchised, or rather—temporarily embarrassed, artist. I was putzing around Malibu—my old college stomping ground, looking for free food; maybe a sample of some gourmet $5 chocolate, and all I got were these photographs.

The most threatened mammal group

on Earth, Madagascar’s five endemic

lemur families (lemurs are found

nowhere else), represent more than 20%

of the world’s primate species and 30% of

family-level diversity. This combination of

diversity and uniqueness is unmatched by

any other country—remarkable considering

that Madagascar is only 1.3 to 2.9% the

size of the Neotropics, Africa, or Asia, the

other three landmasses where nonhuman

primates occur. But lemurs face extinction

risks driven by human disturbance of forest

habitats. We discuss these challenges

and reasons for hope in light of site-specific,

local actions proposed in ...


Environmental Factors Influencing Spring Migration Chronology Of Lesser Scaup (Aythya Affinis), Taylor A. Finger 2014 Western University

Environmental Factors Influencing Spring Migration Chronology Of Lesser Scaup (Aythya Affinis), Taylor A. Finger

University of Western Ontario - Electronic Thesis and Dissertation Repository

Weather likely affects the timing and rate of migration by waterfowl to their breeding grounds. I hypothesized that timing of migration by lesser scaup during spring is affected by annual variation in temperature, precipitation and ice cover. I used satellite telemetry data, waterfowl survey data and corresponding weather data to evaluate competing models that explained variation in timing and rate of migration by lesser scaup. Timing of spring migration occurred earlier and faster when lesser scaup encountered warmer temperatures and greater precipitation, both of which are known to influence thermoregulation and habitat availability for waterfowl. Migration chronology of lesser scaup ...


Understanding The Magnetostructural Transformation In Ferh Thin Films, Melissa Loving 2014 Northeastern University

Understanding The Magnetostructural Transformation In Ferh Thin Films, Melissa Loving

Chemical Engineering Dissertations

Magnetostructural materials demonstrate concurrent magnetic and structural phase transformations which may be driven by changes in temperature, pressure (strain), or magnetic field. The ability to alter the phase transformation via a variety of routes makes these systems the interest of fundamental studies of the physics underlying the transformation, as well as potential technological applications. Equiatomic FeRh, a model magnetostructural material with the chemically-ordered CsCl-type crystal structure, undergoes a first-order phase transition (FOPT) (upon heating) from antiferromagnetic (AF) to ferromagnetic (FM) order with an accompanying 1% (volume) lattice expansion at T~370 K, in bulk. Thin film forms of FeRh provide ...


Animals' Capability To Bond And The Implications That Follow, Falyn Goldfarb 2014 Pace University

Animals' Capability To Bond And The Implications That Follow, Falyn Goldfarb

Honors College Theses

This paper explores the ways in which humans have historically viewed animals, with a focus on Descartes theory automata. Further concepts of the problem of different minds, inherent value, empathy, love, friendship, grief, isolation, anthropomorphism, and biochemistry (focusing on oxytocin, cortisol and the prefrontal cortex) are all explored. Numerous literature reviews are used as examples to fight against the argument that animals are merely machines and can therefore be used and abused. Animal social bonds, including parent-child, purely social, and animal-human, are analyzed for their evolutionary and biological purposes in attempt to highlight the relationships that are not obviously valuable ...


Nesting Ecology Of White-Throated Sparrows (Zonotrichia Albicollis) : The Effects Of Variation In Clutch-Initiation Date And The Application Of Prescribed Fire On Nesting Success, Melissa Olmstead 2014 Wilfrid Laurier University

Nesting Ecology Of White-Throated Sparrows (Zonotrichia Albicollis) : The Effects Of Variation In Clutch-Initiation Date And The Application Of Prescribed Fire On Nesting Success, Melissa Olmstead

Theses and Dissertations (Comprehensive)

The study of nesting success is one of the most widely-used methods for examining the factors governing recruitment in birds. Many ecological influences act together to increase or decrease nesting success, and knowledge of these mechanisms is crucial for determining the habitat or conservation requirements of a given species. One ecological influence is the timing of breeding, which in many species is related to a decline in nest success later in the breeding season. Much of the research on this subject has focused on cavity-nesting species, and the hypothesis that this seasonal decline is caused by a mismatch between clutch-initiation ...

Aquaculture In Regional Australia: Responding To Trade Externalities. A Northern Nsw Case Study., Jeffrey A. Guy, Alistair Mcilgorm, Peter Waterman

Journal of Economic and Social Policy

Australia’s aquaculture industry is predominantly based in rural coastal regions where it makes a significant contribution to local economies as well as to national food security. Over the past decade changing global economic and trade conditions have resulted in Asia supplying an ever-increasing amount of seafood to Australian consumers. From 2003 to 2007 landings of cheaper imported Asian prawns increased dramatically, seriously impacting the eastern Australian prawn farming industry as graphically illustrated by the collapse of prawn farming in the Northern Rivers region of NSW. In response, the Southern Cross University’s National Marine Science Centre researched the feasibility ...
