MODRELL, M.S.*; PRICE, A.L; HANNIBAL, R.L.; PATEL, N.H.; Univ. of California, Berkeley; Univ. of Chicago; Univ. of California, Berkeley; Univ. of California, Berkeley: Regulation of early cell fates in the amphipod crustacean, Parhyale hawaiensis Parhyale hawaiensis, an amphipod crustacean, displays total (holoblastic) cleavage during early embryogenesis, and we hope to determine how tightly cell lineage […]

SANDERS, E.M.*; TERWILLIGER, N.B.; University of Oregon: Regulation of Hemocyanin and Cryptocyanin in adult Cancer magister Several proteins in the hemocyanin gene family are involved in the crustacean molt cycle. Hemocyanin is a copper-containing respiratory pigment that reversibly binds oxygen. Structurally similar to hemocyanin, cryptocyanin lacks several copper-binding histidines. It likely originated from a hemocyanin […]

ROGERS, S.A.*; CORBIN, C.E.; WASSMER, G.T.; Bloomsburg University of Pennsylvania; Bloomsburg University of Pennsylvania; Bloomsburg University of Pennsylvania: Prevalence of nest ectoparasites is independent of group size and nest density in barn swallows (Hirundo rustica) Coloniality has been suggested to have both costs and benefits. A potential cost of living in a group is high […]

FOX, Samuel *; VON KALM , Laurence; University of Central Florida, Orlando: Preliminary characterization of three genes with potential roles linking the RhoA signaling pathway to the ecdysone response in Drosophila epithelia Holometabolous insects undergo metamorphosis involving the destruction of existing larval tissues and the reformation of new cell populations to create adult organs and […]

FESSLER, JL*; WESTNEAT, MW; Field Museum and Univ. of Illinois at Chicago; Field Museum, Chicago: Phylogenetics and Evolutionary History of the Butterflyfishes (Chaetodontidae) Marine butterflyfishes (116 sp.) are conspicuously beautiful and abundant animals found on coral reefs worldwide, yet there remains an absence of a well-supported molecular phylogeny. We present a new molecular phylogeny of […]

HANCOCK, Jennifer A.*; BIKNEVICIUS, Audrone R.; Ohio University; Ohio University: Phylogenetic analysis of foveation in birds The fovea is a specialized area of the retina thought to function to increase visual acuity. Among vertebrates there are a number of different retinal configurations including afoveate, unifoveate and bifoveate. Afoveate and unifoveate retinae are found throughout vertebrates, […]

JENKS, S. M.*; KHAN, S.; TRACY, K.; KENDALL, K.; The Sage Colleges; The Sage Colleges; The Sage Colleges; The Sage Colleges : Photoperiod influence on crayfish agonistic behavior Alterations in monoaminergic neurotransmission are thought to underlie photoperiodic variation in mood, aggression and affective disorders in humans. Research by several investigators on crayfish neurobiology has shown […]
