Meeting Abstract S8.3 Tuesday, Jan. 6 09:00 Acute Estrogen Actions in the Hippocampus: Implications for Epilepsy WOOLLEY, C.S.; Northwestern University cwoolley@northwestern.edu It has been known for decades that estrogens acutely potentiate neuronal excitability and synaptic transmission in the hippocampus, a brain region involved in learning and memory, affective behavior, and in epilepsy. By what cellular mechanisms do […]

Understanding venom variability a challenge for the analytical chemist, an opportunity for the evolutionary biologist
Meeting Abstract S8-4 Wednesday, Jan. 6 09:30 Understanding venom variability: a challenge for the analytical chemist, an opportunity for the evolutionary biologist CALVETE, Juan J.; Instituto de Biomedicina de Valencia, CSIC jcalvete@ibv.csic.es http://www3.ibv.csic.es/index.php/es/investigacion/genomica/upr Adaptive radiation involves the diversification of a lineage into species that differ in phenotypic traits used to exploit different resources. Ecological opportunities arise when […]
Scorpion neurotoxins and their ion channel targets diversity through coevolution
Meeting Abstract S8-6 Wednesday, Jan. 6 11:00 Scorpion neurotoxins and their ion channel targets: diversity through coevolution? ROWE, A.H.*; ROWE, M.P.; Michigan State University; Michigan State University roweashl@msu.edu A goal of venom evolution studies is to identify the causes and consequences of intra- and interspecific variation in venom. Determining the effects of drift and selection is complicated […]

Colubrid snake venoms as a source for understanding biological roles of venoms among advanced snakes
Meeting Abstract S8-9 Wednesday, Jan. 6 14:00 Colubrid snake venoms as a source for understanding biological roles of venoms among advanced snakes MACKESSY, Stephen P.; University of Northern Colorado stephen.mackessy@unco.edu http://www.unco.edu/nhs/biology/faculty_staff/mackessy/mackessy_stephen.htm Snake venoms represent an adaptive trophic response to the challenges confronted by a limbless predator for overcoming fractious prey, and this chemical means of dispatching prey […]
Beak of the Snake Conceptual Frameworks for Assessing Venom as an Adaptive Phenotype
Meeting Abstract S8-11 Wednesday, Jan. 6 15:00 Beak of the Snake: Conceptual Frameworks for Assessing Venom as an Adaptive Phenotype GIBBS, H. Lisle*; HOLDING , Matthew L.; SIMLEY, Sarah A.; Ohio State University; Ohio State University; Ohio State University gibbs.128@osu.edu Intraspecific variation in venom is hypothesized to be adaptive yet conceptual frameworks for testing this idea are […]
