Meeting Abstract 11-6  Saturday, Jan. 4 11:30 – 11:45  Growth, lifespan, and reproductive investment of Physa snails exposed to predators GOEPPNER, SR*; LUTTBEG, B; Oklahoma State University; Oklahoma State University scott.goeppner@okstate.edu Past research has shown that Physa snails change their shell morphology, life history, and behavior based on the type of predators in their environment. The snails […]

Meeting Abstract 11-4  Saturday, Jan. 4 11:00 – 11:15  Feeding of Crayfish Snakes: A Model System for Testing the Roles of Predator Anatomy and Behavior on Foraging Ecology GRIPSHOVER, ND*; JAYNE, BC; University of Cincinnati; University of Cincinnati gripshnd@mail.uc.edu Snakes are a classic example of a gape-limited predator, but ironically gape has been quantified directly in fewer […]

Meeting Abstract 11-7  Saturday, Jan. 4 11:45 – 12:00  Does individual performance influence antipredator behavioral strategy choice in chameleons? DROWN, RM*; ANDERSON, CV; University of South Dakota; University of South Dakota rachel.drown@coyotes.usd.edu Animals are under a constant selective pressure to avoid predation. They are often equipped with several anti-predatory behavior strategies based on their morphology, physiology and […]

Meeting Abstract 11-2  Saturday, Jan. 4 10:30 – 10:45  Differences in behavioral plasticity among populations of threespine stickleback experiencing a novel predation threat. STEVENS II, DR*; GRAHAM, MA; BADJIS, CB; MASON, JN; BAKER, JA; FOSTER, SA; Clark University dalstevens@clarku.edu Rapid, novel changes to an organism’s environment due to invasive species are a global threat to biodiversity. Behavioral […]

Meeting Abstract 11-1  Saturday, Jan. 4 10:15 – 10:30  Calling Owl: Rails Do Not Reduce Vocal Activity Rates in Response to Predation Risk GOLDBERG, DL*; BASSINGTHWAITE, TA; BEILKE, S; WARD, MP; CAPPARELLA, AP; Illinois State University; Illinois State University; Audubon Great Lakes, Chicago; University of Illinois at Urbana-Champaign; Illinois State University dlgoldb@ilstu.edu Animal communication carries the risk […]

ZANI, P.A.*; BRADSHAW, W.E.; HOLZAPFEL, C.M.; LUCERO, K.D.: The Thermal Tolerance of the Pitcher-Plant Mosquito, Wyeomyia smithii We examined the pitcher-plant mosquito, Wyeomyia smithii, from three northern and three southern populations to determine if a latitudinal gradient existed in their thermal tolerance. While many comparative studies among species have demonstrated a robust relationship between thermal […]

BENNETT, V.A.*; KUKAL, O.; LEE, R.E.: Seasonal metabolic depression and mitochondrial degradation in Arctic woollybear caterpillars, Gynaephora groenlandica Gynaephora groenlandica requires 7-14 years to complete its life cycle, overwintering as many times. Because of the short active season (3-4 weeks in June), these caterpillars may spend as much as 90% of their lives in dormancy […]

LERMAN, D.N.*; BETTENCOURT, B.R.; YI, C.H.; KIM, I.; FEDER, M.E.: Response of an hsp70 gene cluster to laboratory and natural selection in Drosophila melanogaster. We investigated whether polymorphisms at the 87A7 hsp70 cluster, which includes 2 of the 5 genes encoding the inducible molecular chaperone/heat-shock protein Hsp70, respond to natural and laboratory thermal selection in […]

Riehle, M. M.*; Bennett, A.F.; Long, A.D.: Genetic analysis of the adaptation to temperature stress: a role for gene duplications Additional copies of certain genes or gene regions have been implicated previously as instrumental players in organismal adaptation to environmental stresses, especially as a means for gene amplification in microorganisms. Six lines of high temperature […]

Shillington, C.: Energy Metabolism and Thermal Ecology of Male Tarantulas (Araneae: Theraphosidae) Male tarantulas of North America engage in intense mate-searching activity during the mating season. They compete for opportunities to mate and their mating success depends largely on rapid walking. Because they are ectotherms, their biological processes are dependent on environmental temperatures, which influences […]
