Meeting Abstract 63.3 Jan. 7 Exposing the embryo to maternal stress: an adaptive predictive mechanism or an unavoidable developmental cost? LOVE, Oliver/P*; WILLIAMS, Tony/D; Simon Fraser University, Canada; Simon Fraser University, Canada olovea@sfu.ca How and why maternal stress affects offspring phenotype has become a subject of considerable interest in studies spanning numerous vertebrate taxa. In birds, embryonic […]

Meeting Abstract 63.3 Tuesday, Jan. 6 Tooth Whorls in Chondrichthyes: The Edestoids, Helicoprion, and other Nightmarish Sharks of the Past LUND, R.*; GROGAN, E.D.; Carnegie Museum; Saint Joseph’s University rlund@sju.edu Tooth arches or whorls of the Edestoid and Helicoprionid Chondrichthyes (Euchondrocephali) of the Upper Paleozoic are borne upon calcified cartilage and bear triangular serrated teeth like those […]
Convergence and parallelism in the evolution of Anolis tail length
Meeting Abstract 63.5 Tuesday, Jan. 6 Convergence and parallelism in the evolution of Anolis tail length MAHLER, D.L.; Harvard University lmahler@oeb.harvard.edu In Anolis lizards, similar environments have spurred the evolution of similar species numerous times. But have these species evolved to look the same via the same mechanisms (parallelism), or has similarity been achieved through different evolutionary […]
Body size within species groups; do snail taxa have a specific size
Meeting Abstract 63.4 Tuesday, Jan. 6 Body size within species groups; do snail taxa have a specific size? DEMAINTENON, Marta; Univ. of Hawaii, Hilo demainte@hawaii.edu Variation in body size within animal taxa involves anatomical differences, which may take the form of differences in cell numbers, cell size, and/ or variation in overall anatomy. Evolutionary decrease in body […]
