Effects Of Slope Upon Hind Limb Kinematics In Chukar Partridge (Alectoris Chukar), Anna T. Kenney 2020 University of Montana

Effects Of Slope Upon Hind Limb Kinematics In Chukar Partridge (Alectoris Chukar), Anna T. Kenney

Undergraduate Theses and Professional Papers

Ground dwelling birds must scale all kinds of complex terrain in order to survive in their natural environments. For instance, Alectoris chukar live on steep hillsides with slopes of up to 60° or 172.3% slope. We undertook the present study to improve understanding of how birds successfully traverse such complex terrain. Using a high speed camera, we analyzed the hind limb kinematics of chukars during normal locomotion on a 10° and 35° incline, decline, and level slope. We compared the data collected from the video recordings, which we had used to identify and digitize the bony landmarks, between all ...


Messy Eating, Samantha King, R Scott Carey, Isabel Macquarie, Victoria Millious, Elaine Power 2019 Fordham University

Messy Eating, Samantha King, R Scott Carey, Isabel Macquarie, Victoria Millious, Elaine Power

Environmental Studies

Literature on the ethics and politics of food and that on animal-human relationships have infrequently converged. Representing an initial step towards bridging this divide, Messy Eating features interviews with thirteen prominent and emerging scholars about the connections between their academic work and their approach to consuming animals as food. The collection explores how authors working across a range of perspectives—postcolonial, Indigenous, Black, queer, trans, feminist, disability, poststructuralist, posthumanist, and multispecies—weave their theoretical and political orientations with daily, intimate, and visceral practices of food consumption, preparation, and ingestion.

Nebraska Cooperative Fish & Wildlife Research Unit -- Staff Publications

Recreational fisheries (RF) are complex social-ecological systems that play an important role in aquatic environments while generating significant social and economic benefits around the world. The nature of RF is diverse and rapidly evolving, including the participants, their priorities and behaviors, and the related ecological impacts and social and economic benefits. RF can lead to negative ecological impacts, particularly through overexploitation of fish populations and spread of non-native species and genotypes through stocking. Hence, careful management and monitoring of RF is essential to sustain these ecologically and socioeconomically important resources. This special issue on recreational fisheries contains diverse research, syntheses ...

Automated Body Condition Scoring: Progression Across Lactation And Its Association With Disease And Reproduction In Dairy Cattle, Carissa Marie Truman 2019 University of Kentucky

Automated Body Condition Scoring: Progression Across Lactation And Its Association With Disease And Reproduction In Dairy Cattle, Carissa Marie Truman

Theses and Dissertations--Animal and Food Sciences

Body condition scoring is a technique used to noninvasively assess fat reserves. It provides an objective estimate to describe the current and past nutritional status of the dairy cow and has been associated with increased disease risk and breeding success. Traditionally body condition scores are taken manually by visual appraisal on a 1 to 5 scale, in one-quarter increments. However, recent studies have shown the potential of automating the body condition scoring of cows using images. The first objective was to estimate the likelihood of disease development and breeding success, using odds ratios, associated with body condition score scored automatically ...


A Sentiment And Content Analysis Of Twitter Content Regarding The Use Of Antibiotics In Livestock, Garrett M. Steede, Courtney Meyers, Nan Li, Erica Irlbeck, Sherice Gearhart 2018 University of Minnesota - Twin Cities

A Sentiment And Content Analysis Of Twitter Content Regarding The Use Of Antibiotics In Livestock, Garrett M. Steede, Courtney Meyers, Nan Li, Erica Irlbeck, Sherice Gearhart

Journal of Applied Communications

On January 1, 2017, the final rule of the Veterinary Feed Directive (VFD) was put into place requiring antibiotics approved for both humans and animals to be discontinued for growth promotion. This change was brought on by the role growth promoters in livestock production play in the development of antibiotic resistance. Antibiotic resistance increases the costs associated with human health care by increasing the length of stays in the hospital and requiring more intensive medical care for patients. The purpose of this study was to explore sentiment and characteristics of social media content and the characteristics of the key influencers ...


Legacy Habitat Suitability Of Eastern Oysters (Crassostrea Virginica) In Louisiana: A Prelude To Mississippi River Delta Freshwater Diversions, Tasia MV Denapolis 2018 University of New Orleans

Legacy Habitat Suitability Of Eastern Oysters (Crassostrea Virginica) In Louisiana: A Prelude To Mississippi River Delta Freshwater Diversions, Tasia Mv Denapolis

University of New Orleans Theses and Dissertations

The Louisiana oyster industry is greatly impacted by freshwater and sediment diversions that are part of the effort to restore the state’s coastline. A habitat suitability index (HSI) proposes species-habitat relationships that can be instrumental in creating impact assessments and suitability predictions for management as new diversions are implemented. An oyster (Crassostrea virginica) HSI was developed using three variables crucial to oyster sustainability: average annual salinity, minimum monthly salinity, and average salinity during the spawning season. These Legacy HSI visualizations show annual fluctuations in the distribution of zones suitable for oyster cultivation prior to proposed diversions in Pontchartrain and ...


Fishing Technologies: Specification And Estimation, Quinn Weninger, Larry Perruso, Helle Bunzel 2018 Iowa State University

Fishing Technologies: Specification And Estimation, Quinn Weninger, Larry Perruso, Helle Bunzel

Economics Working Papers

This paper consistently estimates the structural properties of a multiple-species fishing technology. Our approach overcomes two ubiquitous features of fisheries data generating processes that invalidate classical ordinary least squares estimators: (1) unobservability, by the researcher, of the in situ fish stock and its effect on productivity, and (2) endogenous production decisions that vary with fishermen’s private information about stock abundance and other economic variables. Our estimations obtain consistency by exploiting the timing of production decisions and the information available to fishermen when endogenous production scale and scope, i.e., targeting of individual species’, decisions are made. Our estimator adopts ...

Revision Of The Central Asian Scorpion Genus Anomalobuthus Kraepelin, 1900, With Descriptions Of Three New Species And A Generic Synonymy (Scorpiones: Buthidae), Rolando Teruel, František Kovařík, Victor Fet

Euscorpius

We revise the Central Asian endemic genus Anomalobuthus Kraepelin, 1900, which was considered monotypic for more than 100 years until the recent addition of a second species from Iran (Teruel et al., 2014). We redefine the generic diagnosis of Anomalobuthus and reveal that it is composed of no less than six species, three of which are described as new: A. krivochatskyi, sp. n. (central Uzbekistan and extreme southern Kazakhstan), A. lowei, sp. n. (southeastern Kazakhstan), and A. pavlovskyi, sp. n. (south-central Kazakhstan and extreme northern Turkmenistan). The monotypic genus Psammobuthus Birula, 1911 (described from the Ferghana Valley at the border ...


Employing Natural History Collections In The Aid Of Conservation: Streamlining An Approach To Model Species Distributions En Masse For The Preservation Of Biodiversity, Alice Fornari 2018 The University of San Francisco

Employing Natural History Collections In The Aid Of Conservation: Streamlining An Approach To Model Species Distributions En Masse For The Preservation Of Biodiversity, Alice Fornari

Master's Projects and Capstones

Using species distribution models (SDMs) in Natural History Collections (NHCs) can influence how humans implement conservation changes in flora and fauna communities and ecosystems. Through the use of legacy data (old NHCs and their associated locality/collection information), data correction (background data or pseudo absences added to presence-only data), and the SDM software, Maxent (and its associated geographic information systems or GIS projected models), it has been shown that it is feasible to create a low budget protocol/setup to project the past, present and future of species population changes. This has been done in the past few decades as ...

Rediscovery Of Red Wolf Ghost Alleles In Canid Population Along The American Gulf Coast, Elizabeth Heppenheimer, Kristin Brzeski, Ron Wooten, William Waddell, Linda Y. Rutledge, Michael J. Chamberlain, Et. Al.

School of Forest Resources and Environmental Science Publications

Rediscovering species once thought to be extinct or on the edge of extinction is rare. Red wolves have been extinct along the American Gulf Coast since 1980, with their last populations found in coastal Louisiana and Texas. We report the rediscovery of red wolf ghost alleles in a canid population on Galveston Island, Texas. We analyzed over 7000 single nucleotide polymorphisms (SNPs) in 60 canid representatives from all legally recognized North American Canis species and two phenotypically ambiguous canids from Galveston Island. We found notably high Bayesian cluster assignments of the Galveston canids to captive red wolves with extensive sharing ...

Population Genomic Analysis Of North American Eastern Wolves (Canic Lycaon) Support Their Conservation Priority Status, Elizabeth Heppenheimer, Ryan Harrigan, Linda Rutledge, Klaus-Peter Koepfli, Alexandra L. Decandia, Kristin Brzeski, Et. Al.

School of Forest Resources and Environmental Science Publications

The threatened eastern wolf is found predominantly in protected areas of central Ontario and has an evolutionary history obscured by interbreeding with coyotes and gray wolves, which challenges its conservation status and subsequent management. Here, we used a population genomics approach to uncover spatial patterns of variation in 281 canids in central Ontario and the Great Lakes region. This represents the first genome-wide single nucleotide polymorphism (SNP) dataset with substantial sample sizes of representative populations. Although they comprise their own genetic cluster, we found evidence of eastern wolf dispersal outside of the boundaries of protected areas, in that the frequency ...


Weather--Associated Triggers Of Nesting Activity Of Blanding’S Turtles (Emydoidea Blandingii) In Northeastern Illinois, Emma Buckardt 2018 SUNY College of Environmental Science and Forestry

Weather--Associated Triggers Of Nesting Activity Of Blanding’S Turtles (Emydoidea Blandingii) In Northeastern Illinois, Emma Buckardt

Honors Theses

Environmental triggers of nesting activities in turtles are poorly known, but important for guiding species protection efforts. Blanding’s Turtle (Emydoidea blandingii) is a species of concern throughout much of its range and is thought to prefer to nest on wet warm nights. Weather conditions during the nesting season were analyzed from 2013-2017 of a Blanding’s Turtle population located within the Lake Plain of northeastern Illinois and southeastern Wisconsin to identity climate conditions most associated with nesting activity. Peak nesting dates each year were associated with warmer mean temperature in the preceding months of March, April, and May such ...


Predicting Kidding Date Using Prepartum Milk Calcium Concentrations And Comparing Kid Growth To Colostrum Quality In Goats, Justin Hamm 2018 University of Arkansas, Fayetteville

Predicting Kidding Date Using Prepartum Milk Calcium Concentrations And Comparing Kid Growth To Colostrum Quality In Goats, Justin Hamm

Animal Science Undergraduate Honors Theses

Abstract

Goats have a very long history with mankind and are commonly used as a nutritious red meat source around the world. The supply of goat meat in the United States does not meet the growing demand from ethnic consumers. This provides an economic opportunity in Arkansas agriculture because goats are uniquely adapted to the Ozark environment. There is a wide gap in caprine research which facilitated the conception of the study’s objectives to determine whether prepartum milk in goats showed a sudden rise in calcium levels within 24 to 48 hours of kidding and to ascertain whether an ...

Identifying And Assessing Conflicts Between Future Development And Current Migratory Bird Habitat Around Farmington Bay, Utah, Aubin A. Douglas

All Graduate Plan B and other Reports

Every year, the Great Salt Lake (GSL) and its associated wetlands provide critical habitat for over 250 migratory bird species from both the Pacific and Central Flyways. The GSL borders the Wasatch Front, which is the fastest growing and most populous region in Utah. To support the ever-increasing working population, the government of Utah aspires to increase the robust economic growth of the region through economic incentives and development of infrastructure. As this area continues to develop, greater pressure will be placed on the surrounding natural resources, including the GSL, its wetlands, and the open space and agricultural land that ...
