BAEZA, J.A.; Univ. of Louisiana, Lafayette: Local mate competition does affect sex allocation in a protandric simultaneous hermaphrodite with low risk of sperm competition For strictly simultaneous hermaphrodites, the local mate competition (LMC) model predicts a positive correlation between the proportion of resources devoted to the male function and mating group size whenever sperm competition […]

MILLER, B L W; Univ. of California, Santa Cruz: Heritable body size and consequences for sex allocation in a simultaneous hermaphrodite, Ariolimax dolichophallus Body size is an important life history trait that is under strong natural and sexual selection. There is often a difference in the importance of body size between the sexes, and natural […]

BEESE, K.*; BAUR, B.; Univ. of Basel, Switzerland: Coevolution of reproductive traits in a hermaphroditic land snail Postcopulatory sexual selection arising from interactions between the sexes can lead to a rapid evolution of reproductive traits and may contribute an important part to the speciation process. A correlated evolution between sperm traits and certain dimensions of […]

ELLIOTT, JK*; CHAMBERS, R; MCKINLEY, M; YOUNG, E; University of Puget Sound, Tacoma: The influence of predation on the distribution and abundance of an introduced mussel Introduced species are considered to be one of the largest threats to biodiversity in marine ecosystems because they can displace and/or hybridize with native species, and significantly alter food […]

WOLF, B. O.; MCKECHNIE, A. E.; WARNE, R. ; MATHIASEN, C.; Univ. of New Mexico; Univ. of Witwatersrand; Univ. of New Mexico; Univ. of New Mexico: The functional importance of columnar cacti as resources for a desert bird community; an assessment using stable isotopes Columnar cacti are prominent features of arid and semi-arid ecosystems in […]

MEYER, J* J; BYERS, J E; University of New Hampshire; University of New Hampshire: Sublethal predation facilitates lethal predation: consequences of siphon cropping on two intertidal bivlave species In soft-sediment marine communities, fishes often crop the extended feeding siphons of buried clams. This potentially causes clams to reduce their burial depth thereby enhancing their susceptibility […]

SHIKUMA, N. J.; HADFIELD, M. G. ; Univ. of Hawaii; Univ. of Hawaii: Revealing bacterial biofilm community composition and its role in inducing metamorphosis of the tubeworm Hydroides elegans The succession of sessile biofouling invertebrates is known to occur around the world, however the mechanisms behind this phenomenon have yet to be explained. Specific cues […]

JANES, D.E.; WAYNE, M.L.; Harvard Univ.; Univ. of Florida: Quantitative Genetic Variation in Sex-Determining Response to Incubation Temperature in Leopard Geckos Among vertebrates, sex is determined by one of two recognized mechanisms: environmental or genetic sex determination in which sex is determined by incubation environment or genetic contribution of parents, respectively. The adaptiveness of one […]

LEBLANC, A.M.*; ROSTAL, D.C.; WIBBELS, T.; Georgia Southern University; Georgia Southern University; University of Alabama at Birmingham: Natural Pivotal Temperature and Sex Ratios of Loggerhead Sea Turtles (Caretta caretta) Nesting on Two Georgia Barrier Islands Temperature-dependent sex determination was studied in loggerhead sea turtles (Caretta caretta) nesting on two Georgia barrier islands during the 2000-2003 […]
