Abiotic Factors Influencing Anuran Occupation Of Neotropical Brazilian Caves, Vinícius F. Sperandei, Willian Vaz-Silva, Tejerina-Garro L. Francisco

International Journal of Speleology

Despite increasing research on the Neotropical underground environment, anurans remain poorly understood in this habitat. It was analyzed scientific literature records of anurans in Brazilian natural caves and performed a redundancy analysis (RDA) to identify the environmental, taxonomic, geographic, geological and land-use variables that influence their cave occupancy. It was examined a total of 247 literature records, encompassing 83 species/morphospecies, which revealed distinct cave-dwelling tendencies. Some anuran species occupy caves at altitudes between 5 to 21 meters above sea level (m asl), in areas characterized by rocky outcrops and grassland. Others are associated with caves surrounded by forest, savanna, pasture …

To investigate the impacts of dietary Bacillus-based probiotics and yeast-derived prebiotics on the hepatic transcriptome profile, 500 Hisex White laying hens were randomly allotted into five dietary treatments from 37 to 52 weeks of age: control; control + Bacillus subtilis; control + Bacillus subtilis and Bacillus licheniformis; control + Bacillus coagulans; and control + Saccharomyces cerevisiae yeast cell wall. Transcriptome analysis revealed a substantial number of differentially expressed genes exclusively between the control and prebiotic groups, identifying 2221 genes (FDR ≤ 0.05), with 980 genes upregulated (log2 fold change 0.69 to 24.62) and 1241 downregulated (log2 fold change −0.74 to …

Effects Of Cryoprotective And Mitochondrial Stabilizing Agents On Vitrified Bovine Oocytes, Allison Hoang

LSU Master's Theses

Oocyte vitrification success is highly dependent on cryoprotectant agent (CPA) choice as well as possible additives that could help preserve mitochondrial membrane potential (mMP), reactive oxygen species (ROS) production, and calcium homeostasis within the cell. It is a delicate balance between levels needed for proper oocyte function and activation and levels needed to induce apoptotic pathways. The results of oocyte cryopreservation determine the eventual oocyte viability and subsequent fertilization and embryo development.

In this study potential permeating cryoprotectant combinations were explored such as ethylene glycol (EG) and propylene glycol (PG) or EG in combination with dimethyl sulfoxide (DMSO). Also, the …

Identification, Abundance, And Behavior Of North American Bobcat (Lynx Rufus) Along Road Mitigation Structures Designed For Endangered Species In South Texas, Victoria Hanley, Kevin W. Ryer, Md. Saydur Rahman, John H. Young Jr., Richard J. Kline

School of Integrative Biological & Chemical Sciences Faculty Publications

Endangered species are increasingly used as the target species in implementing and constructing new wildlife crossing structures (WCS). Highways in South Texas fragment the landscape and result in high road mortality for endangered species such as ocelots (Leopardus pardalis, a medium-sized spotted wild cat). In response, the Texas Department of Transportation constructed nine WCS on Farm-to-Market 106 (FM 106), a road which bisects Laguna Atascosa National Wildlife Refuge in Cameron County, Texas. With ocelots being rare and elusive, bobcats (Lynx rufus) are often used as a surrogate species to study felid behavior at road mitigation structures …

Studies of cetacean diving behavior in multiple locations in different ocean basins allow for an assessment of variability within and among populations. We examine foraging dive behaviors of goose-beaked whales (Ziphius cavirostris) and dense-beaked whales (Mesoplodon densirostris) using data from 132 tagged whales in seven locations in the Pacific and Atlantic Oceans and the Mediterranean Sea. Acoustic recording tags are used to identify foraging dives by the presence of echolocation. For other tag types, foraging dives are identified based on maximum dive depth. Five parameters are used to characterize foraging dives: maximum dive depth, foraging dive duration, dive cycle duration, …

Small Meat Processor Needs Are Similar Across Region, Jordan C. Wicks, Alexis Wivell, Thomas Archibald, David Gerrard

Journal of Extension

This needs-based assessment provides insight into the challenges of small meat processors in two regions of the US. On-line surveys were provided to processors and despite regional differences, data show approximately 70% of processors in each state find retention of skilled labor the greatest challenge in maintaining current levels of operation and impede future growth. These findings suggest educational and certification programing may help improve small processor viability and mitigate local food security concerns. Given the disparity in animal production and livestock availability between these diverse states but similarity in responses, we posit this information is translatable across the US.

Economic Analysis Of Stockers Grazing Botanically Diverse Summer Annual Pasture, Kelly M. Mercier, Christopher D. Teutsch, S. Ray Smith, Kenneth H. Burdine, Eric S. Vanzant, Edwin L. Ritchey

Journal of Extension

Economic analyses were performed to determine the feasibility of retaining weaned fall-born calves on summer annual pastures (a monoculture, a 3-species mixture, or a 12-species mixture). Average daily gain was reduced by 0.3 lbs/day in calves grazing the complex mixture in two out of three years. Enterprise budgeting illustrated that retaining calves on summer annual forages was not economical. Two-way net return tables indicated that this scenario would only be profitable when cattle prices are high and pasture establishment costs are low. Extension educators should be sure to emphasize the economic risks when discussing these systems.

Isolation And Divergence Of Greater Earless Lizards (Phrynosomatidae: Cophosaurus) In Western North America Support Multiple Diversification Processes And A Complex Demographic History, Christopher Robert Blair, Carlos Joaquín Pavón-Vázquez, Qaantah Rana, Keaka Farleigh, Erika Crispo, Thomas Panzera, Felipe De Medeiros Magalhães, Britt White, Uri Omar Garcia-Vazquez

Publications and Research

The Southwestern US and northern Mexico continue to serve as ideal regions to elucidate the suite of ecological and evolutionary processes influencing lineage diversification. The complex geological history of arid North America, coupled with paleoclimate change during the Pleistocene and diverse ecoregions makes a multipronged approach to hypothesis testing necessary. We combine thousands of loci from a genotyping-by-sequencing (GBS) approach along with mitochondrial DNA (mtDNA) sequences from the Greater Earless Lizard (Cophosaurus texanus) to examine diversity and test for cryptic population structure. We also apply recently developed coalescent approaches in a Bayesian framework to estimate migration rates. Population …

Turkish Journal of Veterinary & Animal Sciences

In this study, the relationship between the Growth Differentiation Factor-9 (GDF9) gene polymorphism and birth weight, as well as weights on days 30, 60, 90, was investigated in Akkaraman lambs, one of the indigenous sheep breeds of Türkiye. For this purpose, a total of 314 lambs were genotyped by PCR-RFLP method for the single nucleotide polymorphism (SNP) c.260G>A in the GDF9 gene. While GG and GA genotypes were observed in the studied breed, the AA genotype was not observed. The results showed that Akkaraman lambs were in Hardy–Weinberg (H–W) equilibrium for the GDF9-c.260G>A polymorphism (p < 0.05). In this study, a significant association was observed between GDF9-HhaI polymorphism and 30th day weight and 60th day weight in Akkaraman lambs. When the animals were analyzed according to birth type, it was observed that this factor was associated with birth weight, as well as weights on days 30, 60, and 90. It is suggested that the c.260G>A coded SNP …

Snake Spirits, Fishermen And Water Birds On Lake Victoria: A Case Study Of Cultural Conservation In The Musambwa Islands, Uganda, And Prospects For Tourism To Improve Local Livelihoods, Joel T. Heinen, Henry Batenda

Journal of Ecological Anthropology

Abstract.

Using a combination of site visits, document reviews, focus group and key informant surveys of fishermen, we explore the cultural beliefs, taboos and norms that protect Musambwa Islands, Uganda. The islands form part of a large protected wetland with nesting habitat for thousands of water birds and a large population of highly-venomous forest cobras that coexist in and around fishermen dwellings. There are strong taboos against cutting trees, allowing women on the island, and harming cobras. We present some of our ideas on how to improve the economic situation of fishermen through the promotion of nature-based and cultural tourism …

Successful Artificial Incubation And Juvenile-Rearing Of Dropped Eggs Of A Critically Endangered Freshwater Crayfish (Cherax Tenuimanus), Rodney Duffy Dr., Blaine Hodgson, Amber Quinn, Marcus Newman

Fisheries Research Articles

One-third of the world’s freshwater crayfish species face extinction risk, necessitating extreme and urgent conservation measures such as captive rearing. Little information exists on these measures for most threatened species. The hairy marron, Cherax tenuimanus (Parastacidae), is a critically endangered freshwater crayfish endemic to the Margaret River in south-western Western Australia. C. tenuimanus is being rapidly replaced by the smooth marron, Cherax cainii, a translocated congener, causing its progressive decline in range, and now it faces imminent extinction in the wild. Attempts at captive breeding have resulted in few occurrences of egg laying of C. tenuimanus, which ended in complete …

From Larvae To Livelihoods: Examining The Realities Of Black Soldier Fly Farming In Malawi, Emily Herriott

Capstone Collection

Black Soldier Fly (BSF) larvae offer a cost-effective, nutrient-rich alternative to synthetic fertilizers and conventional feed inputs such as soy, fishmeal, and maize bran in sub-Saharan Africa. In Malawi, where smallholder farmers grapple with declining soil fertility, high input prices, chronic food insecurity, and livestock nutritional challenges, BSF farming is emerging as a promising circular agricultural innovation. Despite its technical promise, the social, economic, and ecological realities of BSF adoption remain underexplored.This study investigates the early implementation of BSF farming in Malawi through the Sustainable Livelihoods Framework, focusing on farmer experiences, challenges, and the social and structural processes shaping uptake …

Background: Severe fever with thrombocytopenia syndrome virus (SFTSV) is a highly pathogenic bunyavirus with a high case-fatality ratio for which there is no approved vaccine. Studies have assessed different vaccine technologies. However, few studies have yet assessed the immunogenicity of heterologous prime-boost regimens. Methods: Here, we compare a lipid nanoparticle (LNP)-encapsulated nucleoside-modified mRNA-based vaccine encoding the SFTSV glycoproteins, Gn and Gc, to our recently described recombinant VSV SFTSV (rVSV-SFTSV) vaccine in single dose, homologous, and heterologous prime-boost regimens in mice. Results: We show that all regimens protect from pathogenic SFTSV challenge and elicit strong long-lasting antibody responses. Furthermore, strong cellular …

Genetic And Environmental Factors Contributing To The Pathogenesis Of Vertebral Osteomyelitis Caused By Enterococcus Cecorum In Broiler Chicken, Ummu Syauqah Al Musyahadah, Andi Asnayanti, Anh Dang Trieu Do, Adnan Alrubaye

Poultry Science Faculty Publications and Presentations

Enterococcus cecorum (EC) is the primary cause of Vertebral Osteomyelitis (VO) in poultry, characterized by a hock-sitting posture with legs extended forward. The disease begins with intestinal colonization, where pathogenic strains of E. cecorum establish themselves in the gut within the first week of a bird's lifecycle and translocate to the bloodstream later, reaching the organs, which finally infect the birds' Free Thoracic Vertebrae (FTV). Several factors contribute to the initiation and progression of the disease. Environmental factors such as heat stress, high blood sugar levels, prior infections, overcrowding, and rapid growth conditions weaken immunity and stimulate the emergence of …

Abundance, Distribution, And Shoaling Of Driftfishes And Allies (Scombriformes: Stromateoidei) In The Pelagic Gulf Of Mexico, Juliet Tretler

All HCAS Student Capstones, Theses, and Dissertations

The suborder Stromateoidei contains 80 species of mesopelagic fishes in five families distributed throughout temperate and tropical seas worldwide, including the Gulf of Mexico (Gulf hereafter). Mesopelagic fishes, especially those that spatially aggregate, serve as important forage items for commercially, recreationally, and ecologically important species of fish, marine mammals, and seabirds. However, knowledge of the ecology and trophic importance of stromateoid fishes in the Gulf is extremely limited. This study provides quantitative information on the species composition, abundance, distribution, and biomass contribution of the stromateoid species to the Gulf deep-pelagic fish assemblage, with comparison to “archetypal” mesopelagic fish families (e.g., …
