Meeting Abstract 2.2  Thursday, Jan. 3  The Pleistocene Encruster Scene: Comparison of Epibionts on Molluscan Shells from Different Habitats VON DASSOW, YJ*; DROSER, ML; Carnegie Museum of Natural History; Univ. of California, Riverside yasmin.vondassow@gmail.com Encrusters are sessile, suspension feeding, marine organisms such as bryozoans, barnacles, and tube-building worms, that live permanently attached to a substratum. They are […]

Meeting Abstract 2.3  Thursday, Jan. 3  Intrapopulation Genetic Variation Facilitates Niche Expansion AGASHE, Deepa; University of Texas, Austin deeps@mail.utexas.edu Evolutionary theory posits that adaptive potential is proportional to additive genetic variation in a population, implying that the rate and degree of adaptation to a novel environment increases with the amount of existing genetic variation for relevant traits. […]
