Relationship Of Winter Hair Coat Shedding Ability Of Purebred Angus Dams With Mineral Status, Apparent Forage Digestibility, Uterine Artery Hemodynamics, And Calf Growth And Development, Randy Hunter Burnett
Relationship Of Winter Hair Coat Shedding Ability Of Purebred Angus Dams With Mineral Status, Apparent Forage Digestibility, Uterine Artery Hemodynamics, And Calf Growth And Development, Randy Hunter Burnett
Theses and Dissertations
Winter hair coat shedding ability in southern U.S. cattle production has previously been associated with differences in adjusted birth and weaning weights of calves from dams that shed by June or later (Gray et al., 2011; Cauble et al., 2019). This study was developed to research possible avenues of why these relationships exist with winter hair coat shedding ability. The primary objectives of the following experiments were to: 1) evaluate how mineral status relates to winter hair coat shedding ability, 2) evaluate how winter hair coat shedding ability relates to apparent digestibility of forage, 3) evaluate winter hair coat shedding …
Divergent Selection For Water Conversion Ratio In Broiler Populations, Joseph Hiltz
Divergent Selection For Water Conversion Ratio In Broiler Populations, Joseph Hiltz
Graduate Theses and Dissertations
Water scarcity is a global reality and with the anticipated population growth, freshwater resources will be further strained to meet both human needs and agriculture applications. To ensure a water sustainable and food secure future, all aspects of agriculture must become more efficient. Two strategies were explored. The potential of improving water efficiency in broilers was examined. The first strategy was to develop a more efficient and accurate method for measuring water consumption/inputs in agriculture. To date, water measuring technology has lacked the necessary sophistication to assure accuracy and repeatability of low flow water usage.
After establishing a low flow …
Dna Barcoding Enhances Large-Scale Biodiversity Initiatives For Deep-Pelagic Crustaceans Within The Gulf Of Mexico And Adjacent Waters, Carlos Varela
Dna Barcoding Enhances Large-Scale Biodiversity Initiatives For Deep-Pelagic Crustaceans Within The Gulf Of Mexico And Adjacent Waters, Carlos Varela
FIU Electronic Theses and Dissertations
In this dissertation I investigate the biodiversity of marine deep-water crustaceans of the Gulf of Mexico and adjacent waters, focusing on pelagic crustaceans. Taxonomic and molecular techniques were utilized to document adult and larval crustacean specimens to better under their taxonomy, life history, evolutionary relationships and cryptic biodiversity. The use of molecular techniques to study organisms from habitats with limited accessibility provides tremendous potential. With prevalent anthropogenic threats and the delicate nature of deep-water habitats, the need to improve our understanding of these systems is clear. Molecular techniques can act as a fundamental tool to complement traditional taxonomy. The application …
Invasion Genetics Of The Non-Native Geckos Phelsuma Grandis Gray 1870 And Gekko Gecko (Linnaeus 1758) In Southern Florida, Usa, Thomas William Fieldsend
Invasion Genetics Of The Non-Native Geckos Phelsuma Grandis Gray 1870 And Gekko Gecko (Linnaeus 1758) In Southern Florida, Usa, Thomas William Fieldsend
FIU Electronic Theses and Dissertations
Biological invasions cause tremendous damage to ecosystems, economies, and human livelihoods worldwide. Florida is home to more established non-native species of reptiles and amphibians than anywhere else on Earth, many of which cause substantial harm to native biodiversity and human well-being. The relatively new discipline of invasion genetics promises to significantly improve the understanding, prediction, prevention, and management of biological invasions. The purpose of this dissertation is to utilize invasion genetics techniques to further understanding of the patterns and processes of biological invasions, especially as they pertain to Florida’s destructive and diverse non-native squamate reptile assemblage. In the first phase …
Population Genetic Analyses Of Arctic Char (Salvelinus Alpinus) Life History Types In Nettilling Lake & Amadjuak River Ecosystem: A Test Of Reproductive Isolation, Chen Liu
Electronic Theses and Dissertations
A great number of studies have identified strong genetic differences between sympatric anadromous and resident populations of Salmonidae. However, Arctic char (Salvelinus alpinus) migratory phenotypes in the Nettilling Lake and Amadjuak River ecosystem in Nunavut, Canada have not been genetically characterized, and it remains unclear if distinct genotypes and phenotypes associated with migratory life history differences are maintained through reproductive isolation, and they have been assumed to be sympatric populations, or co-occurring populations. Co-occurring Arctic char (n=225) were sampled from eleven sites along the Amadjuak River in 2014 and 2015. Twelve microsatellite loci were used to quantify genetic variation among …
Otoliths Of South-Western Australian Fish: A Photographic Catalogue, Chris Dowling, Kim Smith, Elaine Lek, Joshua Brown
Otoliths Of South-Western Australian Fish: A Photographic Catalogue, Chris Dowling, Kim Smith, Elaine Lek, Joshua Brown
Fisheries research reports
Due to the species-specific nature of otoliths and given they are often the only part of the fish preserved when fish die, otolith catalogues can be used in numerous applications, such as diet studies in fish eating animals, including pinnipeds, fish and sea birds; archaeological purposes such as reconstructing indigenous people’s diets from otoliths found in middens or evolutionary history of fish species by comparing fossilized otoliths. Given the unique mixture of subtropical and temperate fish, including many endemic species that occur off the southwest corner of WA having a catalogue for this area is extremely important for people working …
A Reevaluation Of The Phylogeography Of The Chattahoochee Slimy Salamander (Plethodon Chattahoochee) Using Next-Generation Genomic Data, Jadin Cross
Symposium of Student Scholars
The Plethodon glutinosus species complex is a group of large-bodied, lungless salamanders that are widespread across the eastern United States. Species in this group are morphologically cryptic and were originally delimited using allozyme data, but in most cases, the extent of contemporary gene flow between named taxa has not be rigorously evaluated. The Appalachian Mountains of northern Georgia are home to several members of this group—including P. glutinosus, P. teyahalee, P. chlorobryonis, and P. chattahoochee. P. chattahoochee has been found to be especially cryptic both morphologically and genetically as both intraspecific genetic variation and species boundaries within …

Comparison Of Gray Squirrel (Sciurus Carolinensis) And Fox Squirrel (Sciurus Niger) In Order To Explore Genes That Confer A Fitness Advantage, Joshua Franzen
Comparison Of Gray Squirrel (Sciurus Carolinensis) And Fox Squirrel (Sciurus Niger) In Order To Explore Genes That Confer A Fitness Advantage, Joshua Franzen
UNO Student Research and Creative Activity Fair
Mutations in the MC1R gene is associated with melanism, or black fur, and the presence of a 24 base pair deletion in the MC1R gene of fox and gray squirrels suggests a shared ancestry between the two species. This could be due to a mutation in a common ancestor or previous mating between species. Evidence has shown that the most likely cause for the presence of MC1R in both species is previous mating between species. If this did occur, then it is possible that other genes traveled between species along with the mutated MC1R gene. Conserved genes shared between species …

Much like humans, chimpanzees occupy diverse habitats and exhibit extensive behavioural variability. However, chimpanzees are recognized as a discontinuous species, with four subspecies separated by historical geographic barriers. Nevertheless, their range-wide degree of genetic connectivity remains poorly resolved, mainly due to sampling limitations. By analyzing a geographically comprehensive sample set amplified at microsatellite markers that inform recent population history, we found that isolation by distance explains most of the range-wide genetic structure of chimpanzees. Furthermore, we did not identify spatial discontinuities corresponding with the recognized subspecies, suggesting that some of the subspecies-delineating geographic barriers were recently permeable to gene flow. …

Will There Be Changes In Sexually Differentiated Behaviors In Mice Manipulated For The Sry Gene As They Mature Into Adultood?, Subin Joo
CMC Senior Theses
Sexually differentiated behavior has been shown to be affected by both genes and hormones. The discovery of the SRY gene, which codes for the development of testes, lead to the development of the Four Core Genotypes model of mice, and the separation of sex chromosomes and its resulting gonadal hormones. Using the FCG model, this study aims to look at the development of sexually differentiated behavior in mice, and track how it changes throughout their life. FCG mice will be divided into individual and social housing, and repeated experiments carried out to test their reaction to both intact female and …
Population Genetics Of A Reintroduced Fisher (Pekania Pennanti) Population In West Virginia, Caroline E. Harms
Population Genetics Of A Reintroduced Fisher (Pekania Pennanti) Population In West Virginia, Caroline E. Harms
Graduate Theses, Dissertations, and Problem Reports
Fishers (Pekania pennanti) were reintroduced in West Virginia in 1969 with no population wide genetic analysis ever having been conducted. Genetic analysis of reintroduced populations is vital to assess genetic diversity as an indicative of population viability. My objective was to collect fisher samples throughout West Virginia, nearby states where fisher may be migrating (PA and NY), and the New Hampshire source population to provide a full genetic interpretation of the reintroduced West Virginia population. Genetic analysis was used to measure genetic diversity, admixture or delineation of subpopulations, and effective population size. Sample location and genetic data were …
A Quantitative Genetic Analysis Of Commercial Traits In Polyploid Crassostrea Virginica, With An Evaluation Of Strategies For Genetic Improvement Of Triploids, Joseph L. Matt
Dissertations, Theses, and Masters Projects
Triploids are a popular product in commercial oyster aquaculture and make up most of the hatchery-produced Crassostrea virginica farmed in the Chesapeake Bay. Despite their importance to commercial aquaculture, the potential of genetically improving triploid C. virginica from selective breeding and breeding strategies for their improvement had not been evaluated. In this dissertation, the prospect of improving triploid C. virginica through selective breeding was assessed with a quantitative genetic analysis from a field test, and breeding strategies for genetically improving triploids were compared by computer simulation. Heritability and genetic correlations involving commercial traits in triploids, including mass mortality associated with …
Stock Composition Of Striped Marlin (Kajikia Audax) In The Central North Pacific Ocean Inferred By Analyses Of Genome-Wide Molecular Markers, Jackson Martinez
Stock Composition Of Striped Marlin (Kajikia Audax) In The Central North Pacific Ocean Inferred By Analyses Of Genome-Wide Molecular Markers, Jackson Martinez
Dissertations, Theses, and Masters Projects
Relative to many highly migratory fishes, Striped Marlin, Kajikia audax, exhibit considerable stock structure. At least four genetically distinct stocks of Striped Marlin have been delineated in the Pacific and Indian oceans, although stock composition in the central North Pacific (CNP) remains unclear and the presence of an additional stock in the North Pacific has been suggested in two recent studies. The goals of this research were to clarify the number of Striped Marlin stocks in the North Pacific and utilize temporal sampling to better understand the stock dynamics of Striped Marlin exploited by the Hawaii-based pelagic longline fishery (HBPLLF). …
