MENZE, M.A.*; HAND, S.C.; Louisiana State University; Louisiana State University: Lessons in Apoptosis from an Invertebrate Extremophile, Embryos of Artemia franciscana Embryos of the brine shrimp A. franciscana are exceptional in their ability to tolerate anoxia and desiccation at room temperature for years and to maintain viability under conditions that are known in mammalian species […]

SECOR, Stephen M.; University of Alabama: Heart position in snakes, ontogenetic shifts and correlation with other organs It has been hypothesized for snakes that heart position is adaptively link to habitat. From aquatic to terrestrial to arboreal habitats as snakes are more often vertically oriented, there is an increase tendency for their hearts to be […]

Meeting Abstract 9.0  Jan. 4  Energy maximization strategies of two surface deposit-feeding gastropods. MAHON, H. K. *; DAUER, D. M.; Old Dominion University; Old Dominion University hmahon@odu.edu Surface deposit-feeders rely on a poor food source; therefore, many have evolved strategies to increase sediment processing efficiency and to maximize net energy gain. Two strategies are patch selection and […]
