Quantifying Costs And Benefits Of Alternative Overwintering Strategies In A Southeastern Population Of Timber Rattlesnakes (Crotalus Horridus), John Powers, Amber Stubbs, Alfred J. Mead, Dominic L. Desantis

Temperate reptile populations are under strong selective pressure to minimize the costs of extreme winter temperatures. For high latitude and high elevation snake populations, this has often favored communal overwintering behavior, wherein large numbers of conspecifics aggregate at optimal sites given the limited availability of such features in the environment. Timber Rattlesnakes (Crotalus horridus) are distributed across a wide latitudinal gradient in North America, and therefore represent ideal models for exploring how variable winter selective regimes might favor different strategies. Here, we leverage a unique intermediate population of C. horridus from central Georgia, USA, that exhibits both communal …

Aedes aegypti is a primer vector of dengue virus (DENV) and chikungunya virus (CHIKV). The susceptibility of mosquitoes to DENV and CHIKV depends on their recognition receptor of pathogens. C-type lectins (CTLs) are an important mediator of virus infection in A. aegypti. This study aims to identify potential receptors and determine the binding affinity between ligand–receptor interaction, CTLs and virus envelopes (DENV-1, 2, 3, and 4 and CHIKV) interaction based on in silico analysis. Sample sequences were obtained from GenBank (NCBI), and 10 CTLs were acquired from VectorBase. Homology modeling based on a minimum standard of 20% was processed …
Compliance And Roughness In Relation To Gecko Locomotion, Brooklynn Campbell
Compliance And Roughness In Relation To Gecko Locomotion, Brooklynn Campbell
Williams Honors College, Honors Research Projects
Geckos move efficiently through a variety of substrates, from swaying branches to wooden fences to the sides of structures. Previous studies have studied locomotion and adhesion on manmade and rough substrates; however, the work is limited when discussing locomotion and adhesion as a relationship of compliance and roughness. Ease of movement was quantified by speed, under the assumption that the faster a gecko moves, the easier it is for the gecko to cross the substrate. Gehyra oceanica geckos from Moorea, French Polynesia were tested on substrates varying in compliance and roughness with four different treatments in total. Compliance, roughness, and …
