Honey bees (Apis mellifera Linnaeus) are important pollinators in natural and agricultural ecosystems and play a key role in global food production. However, colonies are increasingly affected by multiple stressors, including emerging parasites, which can compromise their health and performance. Among these, phorid flies (Diptera: Phoridae) have been observed in association with weak or collapsing honey bee colonies in various regions in Mexico, yet their effects on honey bee behavior and immune function under field conditions remain poorly understood. In this study, we investigated the impact of a phorid fly infestation on the behavior, survival, and immune defense of A. …

Phenotypic Variation Between Surface And Cave-Adapted Poeciliids And Its Effect On Metabolism, Karch Knipp, Michael Tobler, Soren Johnson
Undergraduate Research Symposium
Cave-adapted organisms often exhibit pronounced morphological changes relative to their surface counterparts, a phenomenon known as troglomorphy. In Poecilia mexicana (Atlantic molly), these differences include variation in coloration between surface and cave populations. Troglobitic organisms also typically exhibit reduced metabolic rates, likely as an adaptation to environments with low primary productivity. This makes P. mexicana an ideal system for investigating the evolution of metabolic traits. In this study, we leveraged variation in coloration among cave-dwelling mollies to examine potential associations with resting metabolic rate (RMR). Coloration was quantified using PCR values, and individuals were categorized as “yellow” or “non-yellow.” We …

Relationship Between Morphological And Behavioral Laterality In Astyanax Mexicanus, Allison Lendman, Michael Tobler, Erik Johnson
Undergraduate Research Symposium
Populations within the Astyanax genus have experienced extreme differences in environment, leading to distinct morphological adaptations. The cave populations of these fish are eyeless and have acquired fixed, cranial asymmetries. We explored a possible relationship between this physical asymmetry and behavioral laterality. We tested 28 adult fish, 14 male and 14 female, from the Pachón cave in controlled behavioral trials. We found that both sexes demonstrated behavioral laterality, observed as a consistent left-turn bias in these trials. This supports the hypothesis that these populations display behavioral laterality that is correlated to their physical asymmetries. Ongoing research comparing behavioral patterns in …

Under The Surface: Human Disturbance Reduces Species Richness In Glade Microhabitats, Maddie Smith, Becky Hansis-O'Neill, Aimee Dunlap Phd
Undergraduate Research Symposium
Human disturbance can alter microhabitats in ways that affect biodiversity, especially in sensitive ecosystems like glades where many animals rely on rocks for thermoregulation and refuge. This study examined how rock displacement by human activity influences species richness and community composition in glade habitats at Shaw Nature Reserve and Victoria Glades Conservation Area. We hypothesized that disturbed rocks would be less suitable for wildlife and would support fewer species. From September to November 2025, about 30 rocks per site were pseudo-randomly selected and monitored. Each rock was classified as displaced or nondisplaced, and all organisms found beneath them were recorded. …

The Effect Of Alpha-Lipoic Acid On Sperm Cryobiology And Post-Thaw Quality Of Sperm In Livestock Species, Kashif Ali Malak, Nazar Ali Korejo, Hira Sajjad Talpur, Asmatullah Kaka, Atif Ali Malak, Muhammad Aqeel, Rasool Bux
Journal of Bioresource Management
The cryopreservation of semen is a prerequisite for artificial insemination, germplasm banking and the global distribution of elite livestock breeding. However, spermatozoa are particularly sensitive to cooling and freezing/thawing processes due to the presence of large amounts of polyunsaturated fatty acids in their plasma membranes and limited cytoplasmic antioxidant stores. An increase in reactive oxygen species, lipid peroxidation, mitochondrial dysfunction, acrosomal injury and DNA fragmentation occurs due to stress associated with cryopreservation, which results in the lowering of motility as well as viability and post-thaw low quality of sperm. Alpha-lipoic acid is a natural disulfide compound that acts as a …
