Spatial Ecology Of Large Bodied Ichthyofauna In The Red River Of The North Basin, William Marshall Stuart Dec 2024

Spatial Ecology Of Large Bodied Ichthyofauna In The Red River Of The North Basin, William Marshall Stuart

School of Natural Resources: Dissertations, Theses, and Student Research

Understanding spatial patterns and processes is essential for designing research studies, implementing management actions, and planning restoration efforts. The Red River of the North basin spans a broad geographic area where jurisdictional oversight is divided among several entities (Manitoba, CAN; North Dakota, USA; Minnesota, USA; South Dakota, USA), creating a mosaic of regulatory and functional process zones. Understanding the spatial ecology of freshwater fishes in this disjointed landscape is essential to address diverse life history requirements and the movement constraints imposed by anthropogenic structures. Long-term acoustic telemetry revealed that large bodied ichthyofauna employ a diverse range of movement strategies (i.e., …

Comparing Metabolism And Hypoxia Tolerance Of Native And Non-Native Florida Freshwater Fishes In Climate Change Scenarios, Benjamin A. Share Dec 2024

Comparing Metabolism And Hypoxia Tolerance Of Native And Non-Native Florida Freshwater Fishes In Climate Change Scenarios, Benjamin A. Share

All HCAS Student Capstones, Theses, and Dissertations

As climate change brings rising water temperatures and lower dissolved oxygen (DO) concentrations to freshwater bodies, it has become increasingly important to understand how this will affect ecosystems with established non-native or invasive species. Fishes of the family Cichlidae are the most pervasive non-native fishes in the Everglades and may increase their range further north under a changing climate. To better understand potential invasibility and competition with native fishes, the metabolism and hypoxia tolerance of non-native Blue Tilapia Oreochromis aureus was compared to native Bluegill Lepomis macrochirus when acclimated across a range of seasonal and projected temperatures. Intermittent-flow respirometry was …

Understanding Bigeye Scad (Selar Crumenophthalmus) In Southeast Florida: Age-Growth, Reproduction, And Diet, Mariah France

All HCAS Student Capstones, Theses, and Dissertations

In southeastern Florida, the bigeye scad (Selar crumenophthalmus) is highly regarded as a baitfish for targeting billfish and other large sportfishes, often commanding market prices as live bait exceeding $180 per dozen. Despite its economic significance, there is limited knowledge regarding the species within the Atlantic Ocean, especially the population that occurs in Florida. Bigeye scad were collected monthly from local bait shops in Pompano Beach, Miami, and Islamorada to assess age-growth, reproductive behaviors, and dietary habits. Specimens from May to August had the highest values for length-weight relationships and gonadsomatic index, indicative of a spawning season during …


Providing Proteins To Belizean Residents Through Poultry Products, Ellis Freel Dec 2024

Providing Proteins To Belizean Residents Through Poultry Products, Ellis Freel

Poultry Science Undergraduate Honors Theses

Belize is a food insecure, developing country. Although Belize has plenty of nutritious food in-country, the exportation of that food to generate income contributed to a distribution issue of that nutritious food. More impoverished areas of Belize do not have access to nutritious food because of the lack of affordability and high export rates. Diets with a lack of food, or lack of balanced, nutritious food can negatively impact growth and cognitive development, especially in children. Poultry is one of the only products in Belize not able to be exported. Implementing poultry into Belizean diets would affordably alleviate food insecurity …

Fisheries Research Reports

The Smooth Marron (Cherax cainii) (‘Marron’) is endemic to freshwater dams and rivers of south-west Western Australia. The Recreational Marron Fishery is managed as a single stock within the South-West Recreational Freshwater Resource and is highly vulnerable to over-exploitation due to the biological characteristics of the species (e.g., low fecundity, localised populations) as well as external environmental (e.g., habitat loss, reduction in rainfall) and human factors (e.g., fishing, land clearing).

Due to this vulnerability, this species has been the focus of research, monitoring and management since the 1970’s. Recreational fishing for Marron was first licensed under the Amateur Fisherman’s licence …

Fat Deposition, Β- Carotene, And Vitamin A Metabolism In Bulls, Steers, And Heifers, Tesla Trammell Dec 2024

Fat Deposition, Β- Carotene, And Vitamin A Metabolism In Bulls, Steers, And Heifers, Tesla Trammell

Masters Theses & Specialist Projects

Research highlights the impact of Vitamin A on cattle growth and meat quality. Supplementing Vitamin A early in life has been linked to enhanced IMF content and growth rates in calves, especially when administered at birth or during early developmental stages. This is attributed to the role of the ZFP423 gene in adipocyte formation, with studies noting its involvement in the development of IMF during the finishing phase.

This study aims to add to the present research by evaluate the effect of calves’ sexual class on blood β-carotene and Vitamin A before weaning. The second study evaluated the β- carotene …

Analyzing Head Morphology Trends With Increasing Population Density In A Jamaican Lizard Species, Lillian Durand Dec 2024

Analyzing Head Morphology Trends With Increasing Population Density In A Jamaican Lizard Species, Lillian Durand

2024 Fall Honors Capstone Projects - Archive

Anolis lizards are model organisms for studying natural selection and evolutionary processes. One trait that is hypothesized to be advantageous for males is head size, as larger heads lead to stronger bite forces and increased likelihood in outcompeting other males for mates. To better understand how linked head size and intraspecific competition are, the head morphology of male A. lineatopus was analyzed among Jamaican populations with varying levels of population density. Population densities were determined using standardized plot surveys and mark resight models. Head dimensions and body condition for individual lizards were measured at each site. My study found that …


First Breeding Confirmation For Red-Breasted Nuthatch (Sitta Canadensis) Along The Big Bend Reach Of The Platte River, Jacob C. Cooper, Cody Mcgregor, Letitia M. Reichart, Janet Steele Dec 2024

First Breeding Confirmation For Red-Breasted Nuthatch (Sitta Canadensis) Along The Big Bend Reach Of The Platte River, Jacob C. Cooper, Cody Mcgregor, Letitia M. Reichart, Janet Steele

Nebraska Bird Review

The Red-breasted Nuthatch (Sitta canadensis) is a highly nomadic species of North American nuthatch prone to large movements across the entire continent (Ghalambor and Martin 2020). This behavior has resulted in both a lack of geographic variation across the continent and propensity to colonize isolated patches of suitable habitat (Ghalambor and Martin 2020). In the Bessey District of the Nebraska National Forest (NNF), Red-breasted Nuthatches were one of the first coniferous-forest bird species to colonize and begin breeding in the isolated planted stands of pine (Zimmer 1913, Bray 1994). Despite the increasing number of records for the species …

Fall Field Report, August–November 2024, W. Ross Silcock Dec 2024

Fall Field Report, August–November 2024, W. Ross Silcock

Nebraska Bird Review

First off, I should reiterate that records are only mentioned in this Introduction and in the text when they add to or fine-tune data included in BONO (Birds of Nebraska – Online (outdoornebraska.gov). It was my expectation that as the number of birders and in particular those reporting to eBird continue to increase, gaps in the database will be filled and my job will become simpler. However, this expectation is yet to be realized, likely due to increasing movements and activity among birds that appears to be due to increasing severity of weather events, such as heat, cold, and drought, …

The Relationship Between Chute Behavior And Morbidity In Cattle, Andrea Rankin Dec 2024

The Relationship Between Chute Behavior And Morbidity In Cattle, Andrea Rankin

Animal Science Undergraduate Honors Theses

Most cattle see a handling chute at least once in their lives. Handling plays a huge role in cattle management, whether it’s for transportation, auction sales, deworming, medical treatments, or AI purposes. Morbidity related to Bovine Respiratory Disease (BRD) is one of the biggest causes of economic loss for ranchers and can be related to handling stress. Auction-derived calves (ADC; n=92) were brought to the University of Arkansas Savoy Research Facility for processing and monitoring for behavioral cues and disease. The objective of this study was to find a relationship between the calves’ behavior in the chute and morbidity. The …

The Bacterial Cell Wall Components Lipopolysaccharide And Peptidoglycan Initiate Divergent Local Tissue And Systemic Inflammatory Response Profiles In The Chicken Model, Kristen A. Byrne, Gisela F. Erf

Poultry Science Faculty Publications and Presentations

The innate immune system plays an important role in the early defense against pathogens. To better understand the chicken’s innate inflammatory responses, we concurrently examined the cellular responses at the injection site and in the blood following intradermal (i.d.) injections of lipopolysaccharide (LPS) or peptidoglycan (PGN) into the pulp of growing feathers (GFs). Both LPS from Gram-negative bacteria and PGN from Gram-positive bacteria are potent stimulators of innate inflammatory responses. The time-course study conducted revealed similarly elevated levels of heterophils and macrophages in injected GF-pulps during the first 24 h for both LPS and PGN. However, PGN also stimulated rapid …
