Meeting Abstract 53.5  Tuesday, Jan. 5  Oxygen-induced plasticity and evolution of larval tail morphology in stream and pond-breeding salamanders (genus Ambystoma) LANDBERG, Tobias; University of Connecticut tobias.landberg@uconn.edu Adaptive variation in larval ecotypes has evolved in five salamander families, but the environmental contributions to evolutionary differences are barely explored. Large gills and tail fins contribute to gas exchange […]

Meeting Abstract 53.2  Tuesday, Jan. 5  Comparative morphology and evolution of pilidiophoran larvae (Nemertea) SCHWARTZ, M.L.*; NORENBURG, J.L.; University of Puget Sound; Smithsonian Institution mschwartz@pugetsound.edu Pilidiophoran life-history has been characterized as possessing indirect development via a planktotrophic larva, the pilidium. Although so-called direct development has also been recorded, only six instances are currently known. This dichotomy in […]
