Meeting Abstract P1.44  Wednesday, Jan. 4  Corticosterone, immune function, and behavior in free-living dark-eyed juncos HANAUER, RACHEL E.*; KETTERSON, ELLEN D.; Indiana University; Indiana University rhanauer@indiana.edu Pleiotropic effects of hormones can lead to integration of traits, potentially causing trade-offs that limit an organism’s adaptive responses to different environments. Previous studies in birds have found that the steroid […]

Meeting Abstract P1.112  Wednesday, Jan. 4  Convergence in pharyngeal jaw morphology in Heroine cichlids CLEMMENSEN, S.F.*; HULSEY, C.D.; University of Tennessee, Knoxville; University of Tennessee, Knoxville sclemmen@utk.edu Trophic divergence in cichlids is linked to shifts in pharyngeal jaw morphology. In Heroine (Central American) cichlids, the ability to consume a novel prey type – mollusks – is a […]

Meeting Abstract P1.121  Wednesday, Jan. 4  Connective Tissues of the Craniovertebral Joint in Rajidae CLAESON, Kerin M.; Ohio University Heritage College of Osteopathic Medicine claeson@ohio.edu The craniovertebral joint (CVJ) exhibits arrangements and morphologies of skeletal and connective tissues that vary according to ontogeny and systematics. For instance, within chondrichthyans a broad articulation between the skull and basiventral […]

Meeting Abstract P1.3  Wednesday, Jan. 4  Comparison of Startle Response in Two Ambystomid Species TAYLOR, Z. J.*; MILLIKEN, G. W.; College of Charleston; College of Charleston zjtaylor@g.cofc.edu The ability of sensory systems to detect disturbances in the surrounding environment and select an appropriate startle response determines an animal’s ability to avoid predation. During the aquatic stage, salamander […]

Meeting Abstract P1.53  Wednesday, Jan. 4  Comparative sugar transport by crustacean hepatopancreas and intestine DUKA, A.*; AHEARN, G.A.; U. of North Florida, Jacksonville; U. of North Florida, Jacksonville gahearn@unf.edu Crustacean hepatopancreas and intestine are both sites of nutrient absorption. Glucose is transported in both organs by Na-dependent cotransport, while Na-dependent D-fructose influx has also been described for […]

Meeting Abstract P1.144  Wednesday, Jan. 4  Comparative proteomic analysis of blood sera of venom-resistant and non-resistant ground squirrels under rattlesnake predation BIARDI, James; Fairfield University jbiardi@fairfield.edu Rattlesnake venoms produce a suite of effects, including hemorrhage, myotoxicity, hypovolemic shock, clotting disorders, edema, and paralysis. These arise from a complex mix of enzymatic and non-enzymatic toxins. Our work on […]

Meeting Abstract P1.109  Wednesday, Jan. 4  Comparative adductor mandibula architecture and muscle fiber type composition within Cyprinidae MULLER, LJ*; STAAB, KL; HERNANDEZ, LP; George Washington University larajmuller@gmail.com The adductor mandibula complex of fishes has long been of interest to functional morphologists interested in feeding. In basal teleosts this muscle serves only to close the jaws, while in […]

Meeting Abstract P1.17  Wednesday, Jan. 4  Comparative Transcriptomics of Two Freshwater Mussels, Villosa nebulosa and Villosa lienosa, in Response to Heat Shock PERKINS, Samantha L.*; JENNY, Matthew J.; University of Alabama; University of Alabama mjjenny@bama.ua.edu The impact of stress related to global warming of surface waters has been studied extensively on multiple levels of biological organization. However, […]
