Meeting Abstract 70-1  Wednesday, Jan. 6 08:00  Extent and evolutionary significance of heritable variation in reef-building corals. MATZ, MV; Univ. of Texas at Austin matz@utexas.edu Corals are excellent subjects for quantitative genetics: one can fragment the same colony into clonal replicates and expose them to various treatments, and generate thousands of offspring according to a desired crossing […]

Meeting Abstract 70-3  Wednesday, Jan. 6 08:30  Anthropogenic Effects on the Epigenome of the Túngara Frog (Physalaemus pustulosus) GARCIA, MJ*; RODRIGUEZ, S; TAYLOR, RC; HUNTER, KL; Salisbury University; University of Texas, Austin; Salisbury University; Salisbury University mjgarcia@salisbury.edu Phenotypic responsiveness to changing environmental conditions is mediated, in part, by changes in gene expression due to epigenetic modification. Epigenetic […]

Meeting Abstract 69-6  Tuesday, Jan. 5 14:45  Temporal variation in honeybee microbial symbionts KOVACS, J.L.*; VOISIN, D.; Spelman College; Spelman College jkovacs@spelman.edu Recent losses of honeybee colonies have led to an increased focus on understanding the microbial associations both within honeybee colonies and the honeybees themselves. While advances in sequencing have allowed us to identify the bacterial […]

Meeting Abstract 69-3  Tuesday, Jan. 5 14:00  Profiling gene expression in an intertidal sea anemone (Anthopleura elegantissima) across habitats and symbiotic states DZIEDZIC, K.E.*; MEYER, E.; Department of Integrative Biology, Oregon State University, Corvallis, OR, USA; Department of Integrative Biology, Oregon State University, Corvallis, OR, USA katherine.dziedzic@science.oregonstate.edu Changing ocean conditions are already impacting fitness and distribution of […]

Meeting Abstract 69-7  Tuesday, Jan. 5 15:00  Modulation of cnidarian sphingosine rheostat during symbiosis onset and breakdown KITCHEN, SA*; POOLE, AZ; WEIS, VM; Oregon State University; Oregon State University; Oregon State University kitchens@science.oregonstate.edu Lipids play a central in symbiosis, providing both cellular structure and energy storage, but little is known about how signaling lipids participate in onset […]

Meeting Abstract 69-8  Tuesday, Jan. 5 15:15  Micro-PAM in clams: A system for single-cell-scale spatial resolution of photosynthetic efficiency HOLT, A.L.*; SWEENEY, A.M.; University of Pennsylvania; University of Pennsylvania alholt@physics.upenn.edu We recently described a “solar transformer” in photosymbiotic tridacnid giant clams, an evolved system that functions to redistribute solar flux incident on the clam’s mantle to spatially […]

Meeting Abstract 69-5  Tuesday, Jan. 5 14:30  Like lemmings off a cliff?: Unraveling Symbiodinium migration in octocorals via canonical and non-canonical bleaching pathways PARRIN, AP*; HARMATA, KL; SAMOVA, EL; YAEGER, MA; BLACKSTONE, NW; Northern Illinois University; Northern Illinois University; Northern Illinois University; Northern Illinois University; Northern Illinois University apparrin@gmail.com Octocorals remain one of the understudied groups of […]

Meeting Abstract 69-2  Tuesday, Jan. 5 13:45  Host Cell Division and Symbiont Population Dynamics in the Symbiotic Anemone Aiptasia sp. TIVEY, T.R.*; WAIANUHEA, L.K.; WEIS, V.M.; Oregon State University tiveyt@onid.orst.edu http://tiveyt@onid.orst.edu The cnidarian-dinoflagellate endosymbiosis relies on the cellular coordination of its two partners, algal symbionts and the host cnidarian cells that contain them. We examined the effect […]

Meeting Abstract 69-1  Tuesday, Jan. 5 13:30  Biochemical assessment of the coral-dinoflagellate symbiosis: Enzymes of each partner show evidence of adaptation to different thermal regimes VELASCO, B.; CELA, B.; FIELDS, P. A.*; Franklin and Marshall College; Franklin and Marshall College; Franklin and Marshall College peter.fields@fandm.edu Tropical reef-building corals obtain most of their energy in the form of […]
