Meeting Abstract 20-2  Saturday, Jan. 4 10:45 – 11:00  Genotype-by-temperature effects on thermal preference in the house fly Musca domestica DELCLOS, PJ*; MEISEL, RP; University of Houston; University of Houston pdelclos@uh.edu Environmental temperature strongly affects the physiology of individuals, and so thermoregulation is vital for maximizing an individual’s fitness. Ectotherms largely rely on two mechanisms to thermoregulate: […]

Meeting Abstract 20-3  Saturday, Jan. 4 11:00 – 11:15  Genetic Variation and Molecular Regulation of Cold Hardiness in Spotted Wing Drosophila GARCIA, MJ*; TEETS, NM; University of Kentucky; University of Kentucky mjga237@uky.edu Managing invasive pests requires a thorough understanding of their basic biology including life history traits, resistance to control treatments (e.g. pesticides), and thermal tolerance. Cold […]

Meeting Abstract 20-1  Saturday, Jan. 4 10:30 – 10:45  Distance Matters: Experimental Test of the Influence of Avian Migration Distance on Readiness to Breed in Spring FUDICKAR, AM*; BREWER, DE; Indiana University; Indiana University afudickar@gmail.com Migration in birds often results in individuals dispersing over large geographic areas after the breeding season. Here we asked if within population […]

NISHIGUCHI, M.K.*: Reverse physiological patterns between sepiolid squids and their luminous bacterial symbionts: Host specificity examined from down under. Mutualistic associations between bacteria and their eukaryotic hosts have a variety of mechanisms that determine patterns of host specificity among symbionts during infection and colonization. Although most symbiotic bacteria are only capable of infecting their particular […]

Lickliter, C.L.*; Nishiguchi, M.K.: Phylogenetic characterization of the genus Vibrio based on morphological and molecular data. Vibrio fischeri and Vibrio logei are two species of luminous bacteria (GAMMA-Proteobacteria) that reside as symbionts in the light organs of a variety of sepiolid squids (Cephalopoda: Family Sepiolidae). These squids include the genera Euprymna and Sepiola, which are […]

Trapido-Rosenthal, H.G.*; Zengler, K.; Ritter, J.E.: Multiple Species of Archaea, Cyanobacteria, and Eubacteria Live in Association with the Sponge Chondrilla nucula Marine sponges have been the subjects of natural products chemists’ investigations for many years, and have been the sources from which novel chemicals with interesting properties have been isolated. Many marine sponges harbor large […]

O’BRIEN, J.J.*; BOETTCHER, A.A.; BOONE, E.; SHERMAN, T.D.: Chemical cues and vulnerable hosts: An investigation into factors affecting settlement of Loxothylacus texanus, a rhizocephalan barnacle parasitizing portunid crabs in the Gulf of Mexico The parasitic castrator, Loxothylacus texanus, stunts the growth and inhibits reproduction of economically important portunid crabs in the Gulf of Mexico where […]

OKAMURA, B.*; ANDERSON, C.L.; CANNING, E.U.: An ancient clade of myxozoans parasitic in freshwater bryozoans The Myxozoa, an enigmatic group of endoparasites, is marked by a long history of phylogenetic and taxonomic uncertainty. Originally classified as protists, it is now clear that myxozoans are proper metazoans, although controversy remains as to whether they are highly […]

BRADLEY, TJ; HETZ, S: Specific Dynamic Action in the Insect Rhodnius prolixus Larval instars of the Reduviid bug Rhodnius prolixus take blood meals that are up to ten times their previous body volume. Digestion and absorption of the meal is necessary for growth of the insect prior to the subsequent molt. We measured carbon dioxide […]
