Meeting Abstract 33-2  Saturday, Jan. 4 13:45 – 14:00  Plasticity and the Origin of Evolutionary Pattern FOSTER, S A*; BAKER, J A; Clark University; Clark University sfoster@clarku.edu The role of phenotypic plasticity in evolution has become increasingly apparent in recent years. A primary recent interest has involved the possibility that it could guide evolutionary transitions and influence […]

Meeting Abstract 33-1  Saturday, Jan. 4 13:30 – 13:45  Nitrogen Excretion Plasticity and Reproductive Colonization of Land by Frogs: Multiple Strategies to Avoid Ammonia Toxicity MENDEZ-NARVAEZ, J*; WARKENTIN, K; Boston University; Smithsonian Tropical Research Institute javier0620@gmail.com Ammonia excretion is cheap but requires water; excreting urea helps terrestrial vertebrates conserve water and avoid ammonia toxicity. The desiccation risk […]

WALLACE, B.D.*; HAMMER, H.S.; WATTS, S.A.; LAWRENCE, J.M.; LAWRENCE, A.L.: The effects of dietary protein concentration on growth of juveniles of the sea urchin Lytechinus variegatus . Juveniles (ca. 14 mm diameter, n=120) were collected at St. Joseph Bay, FL in March 2000. They were held in 80 L aquaria with artificial seawater at 21 […]

Hammer, H.S.*; Watts, S.A.; Lawrence, J.M.; Lawrence, A.L.; McClintock, J.B.: The effect of dietary protein concentration on gonad composition and gametic condition in the sea urchin Lytechinus variegatus Ecological studies suggest that nutrition, particularly dietary protein, affects nutrient storage and reproductive competency. Starved urchins (ca. 36 mm diameter, n=12) were held in replicated (3x) 80 […]

TELANG, A.*; CHAPMAN, R.F.; WHEELER, D.E.: Sexual differences in protein and carbohydrate utilization by larval tobacco budworm, Heliothis virescens (F.). Female Lepidoptera are often heavier than males, presumably due to greater food consumption. Our previous studies indicated that female Heliothis virescens caterpillars use both feeding and post-ingestive processing as mechanisms to meet nutrient needs. Our […]

SECOR, S.M.*; NAGY, T.R.: Postprandial response of plasma lipds and the hormone leptin in pythons With each meal, pythons rapidly upregulate gut performance and dramatically increase metabolic rate. We suggest one manner by which pythons fuel these postprandial responses is to mobilize stored energy sources, particularly lipids. To evaluate the mobilization of lipids with feeding […]
