Assessing Localized Recovery And Synchrony Of An Endangered Wetland Species., Aiyana Reissman

Theses

The state and federally endangered light-footed Ridgway’s rail (LFRR; Rallus obsoletus levipes) is central to regional conservation, yet the drivers of its population fluctuations remain poorly understood. The fragmented nature of coastal wetlands in Southern California is threatening the existence of endemic species like the LFRR. Tidal inundation, severe storms, and overpredation threaten the survival of LFRR. This study addresses population fluctuations by analyzing the spatial and temporal drivers of LFRR populations to inform effective, site-specific management.

To do this, a 45-year (1980–2024) LFRR census data set across 16 wetlands throughout its range in California was synthesized. A multi-faceted …

Optimal Drought Management Actions For Cattle Operations On Navajo Nation, Tatiana Drugova, Kynda R. Curtis, Man-Keun Kim

All Current Publications

In this fact sheet, we examine the drought management options available to cattle operations on the Navajo Nation, the largest Native American reservation in the U.S. Specifically, we discuss the results of a study evaluating the economic outcomes of two common drought response strategies: herd reduction and supplemental hay purchases. We also provide recommendations for ranchers on optimal strategies, i.e., those that maximize profits, for two rancher types, differentiated by their willingness to accept (risk-neutral) or avoid risk (risk-averse).

Non-Invasive Monitoring Of Camel Hair From A Free-Grazing Herd As A Biomarker In Linking Environmental Exposure And Nutritional Status In Desert Ecosystems, Ibrahim Albokhadaim

The Thai Journal of Veterinary Medicine

Camels are vital livestock in arid regions, yet their elemental exposure remains underexplored, particularly through non-invasive biomarkers. This study is novel in applying camel hair as a non-invasive, long-term biomarker to assess nutritional adequacy and environmental exposure in a free-grazing desert herd, with age-stratified evaluation of essential and toxic element accumulation. For this purpose, a cross-sectional study was conducted on a herd of 18 apparently healthy camels (≤6 months: 28%; >6 months: 72%). Initially, hair samples were collected, washed, digested, and analyzed using inductively coupled plasma mass spectrometry (ICP-MS). The samples were then analyzed to determine the concentrations of 12 …

The Role Of Exotic Plants In The Diet Of Black-And-White Colobus Monkeys (Colobus Guereza) In Kibale National Park, Uganda, Michelle Gaykov

Theses and Dissertations

Exotic plants have both positive and negative impacts on their environment. They may act as additional food sources for the local fauna or as competition for local flora or leading to changes within a landscape or ecosystem. To considere the role of exotics in primate diet, this study focused on the dietary role of exotic plant species in the diet of a leaf-eating foregut fermenting monkey, the black-and-white colobus monkeys (Colobus guereza) in Kibale National Park, Uganda. Int this study, I followed individuals in two groups of black-and-white colobus monkeys for 21 days recording their food intake (0700-1900). I also …

Genetic Determinants Associated With Persistence Of Listeria Species And Background Microflora From A Dairy Processing Environment, Vaishali Poswal, Sanjeev Anand, Jose L. Gonzalez-Hernandez, Brian Kraus

Dairy Science and Food Science Faculty Publications: 2022 to Present

Listeria monocytogenes is a persistent foodborne pathogen capable of surviving in food processing environments, often in association with diverse environmental microflora. This study examines genomic determinants of persistence, specifically stress adaptation and biofilm-associated traits, in environmental Listeria species and other environmental microflora from a dairy processing facility by analyzing whole-genome sequences of 6 environmental Listeria isolates, 4 ATCC reference strains, and 22 air and floor swab cultures, annotated using the RAST platform. Subsystem analysis revealed that Listeria isolates carried a defined set of genes linked to biofilm formation, antimicrobial resistance, and stress response, though in lower abundance than environmental cultures. …

Behavior Of A Komodo Dragon In Relation To Whole-Prey Feeding, Gurkiran Kaur Natt

Williams Honors College, Honors Research Projects

In zoological settings, whole-prey feeding is an enrichment strategy widely used to prompt naturalistic behaviors; yet, the specific behavioral shifts this causes in reptiles are not well-documented. This study focused on the activity budgets and spatial use of a six-year-old male Komodo dragon (Varanus komodoensis) housed at the Akron Zoo, analyzing his movements in direct response to whole-prey feeding sessions. Over an eight-week observation period, instantaneous scan sampling was utilized to quantify behaviors before and after two distinct whole-prey feeding sessions. Although active behaviors and "not visible" instances increased marginally post-feeding, paired t-tests confirmed these shifts were not statistically significant …

Evaluating Cow/Calf And Stocker Performance When Grazing Sudangrass With And Without Sunnhemp, Shelby L. Davis-Jenkins, Daren D. Redfearn, Mary E. Drewnoski

Nebraska Beef Cattle Reports

Summary with Implications

Sudangrass can provide high-quality summer forage, supporting cow/calf pairs and growing cattle. In this study, sudangrass or a sudangrass–sunnhemp mix was grazed over two years by cow/calf pairs and heavy stockers (~880 lb). There was no difference in carrying capacity between forage types. Sunnhemp inclusion had no effect on cow body condition or nursing calf gain. Cows maintained condition through peak lactation, and nursing calves gained 2.27 lb/day. Stockers gained 1.56 lb/day on sudangrass alone and 1.73 lb/day on the mix. However, the added seed cost of sunnhemp increased the cost of gain in year 1 and …

Largemouth Bass Diet Changes Through The Summer In Central Minnesota, Ethan Kunz

Journal of Earth and Life Science

Largemouth Bass Micropterus nigricans is one of the most widespread fish species in the world, due in part to human introduction for angling. Largemouth Bass are opportunistic predators that will consume the largest prey they can often find; however, it has been shown that their diet mainly consists of invertebrates such as crayfish, with less focus on other fish species. This research aimed to determine what the Largemouth Bass diets in Central Minnesota consist of, and how they may change from the beginning of summer through the beginning of fall. A total of 174 Largemouth Bass were sampled from late …

Relationship Between Ratio Of Hybrid Sunfish To Their Parent Species And Latitude, Maxwell Kattner

Journal of Earth and Life Science

Hybrid sunfish of the Lepomis genus make up a generally small but notable portion of the population of sunfish in Minnesota lakes. Hybrid sunfish play a significant role in freshwater ecosystems across the United States. They are both morphologically and behaviorally distinct in some ways and similar in other ways to their parent species, causing them to both fill and compete with their parent species for niches occupied by multiple Lepomis species. Despite this, the ratio of hybrid sunfish to their parent species has never been properly explored. This study observed if the ratio of hybrid sunfish to their parent …

Effect Of Corn Harvest With A Chopping Head On Performance Of Cattle Grazing Corn Residue, Conner K. Biehler, Mary E. Drewnoski, Jim C. Macdonald

Nebraska Beef Cattle Reports

Summary with Implications

The effects of harvesting corn using a chopping vs a standard, non-chopping combine head on steer performance when grazing corn residue were evaluated. Steers were supplemented with dry distillers grains at 0.6% of initial body weight. The amount of corn residue mass and the quality of the husk did not differ between harvest methods. Steer gains were over twice as high in year 2 (2.10 lb/d) than year 1 (0.76 lb/d), potentially due to greater husk digestibility and milder winter conditions. Corn residue harvested with a standard combine head resulted in a slightly higher average daily gain …

Artificial Insemination Of Beef Heifers With Multi-Sire Semen, Dempster M. Christenson, Jordan M. Thomas, Daniel J. Kelly, Rick N. Funston

Nebraska Beef Cattle Reports

Summary with Implications

This study compared pregnancy rates of beef heifers artificially inseminated with multi-sire semen to single-sire semen. It was hypothesized pregnancy rates resulting from multi-sire semen would be increased compared to single-sire semen. Heifers were artificially inseminated with semen from one of three sires or semen from a combination of the same three sires. Pregnancy rates did not significantly differ. Paternity testing suggests sire parentage can be unequal when semen is mixed from multiple sires. In summary, similar pregnancy rates were observed using single-sire and multi-sire semen, but progeny may have unequal sire representation.
