BEAUMAN, R. L.; KAHN, P. F.; MENDON�A, M. T.; Auburn University: Short-term effects of burrow collapse on corticosterone levels and immune response of gopher tortoises The gopher tortoise is a federally listed species in the western portion of its range, and a species of concern elsewhere. Their burrows are often collapsed and tortoises become entombed […]

Physiological and behavioral effects of nonylphenol and 17β-estradiol on larval survival and smolt development of Atlantic salmon, Salmo salar
LERNER, D. T.*; MCCORMICK, S. D.; University of Massachusetts, Amherst; Conte Anadromous Fish Research Center: Physiological and behavioral effects of nonylphenol and 17β-estradiol on larval survival and smolt development of Atlantic salmon, Salmo salar Nonylphenol (NP) is widely found in effluents from sewage treatment plants and industrial sites due to its use in detergents, plastics, […]

Endocrine Disruption and Thyroid Adaptation in Quail
MCNABB, F.M.A.; QUERAL-KIRKPATRICK, L.T.; Virginia Tech; Virginia Tech: Endocrine Disruption and Thyroid Adaptation in Quail We studied the effects of sustained ammonium perchlorate (AP) exposure (.013-4,000 mgAP/l [ppm] in drinking water) for up to 8 weeks on chicks and adult bobwhite quail. AP competitively inhibits iodide uptake into the thyroid gland. We measured plasma thyroid […]

LANDYS, M.M.*; DECENCIERE, B.; GOYMANN, W.; SLAGSVOLD, T.; Univ. of Oslo; Univ. of Oslo; Max Planck Institute for Ornithology, Andechs; Univ. of Oslo: Effects of cross-fostering on territorial aggression and plasma testosterone in the blue tit: testing the �challenge hypothesis� Gonadal testosterone plays an important role in the support of territorial aggression in many breeding […]
Polyembryony in spermcast simultaneous hermaphrodites a twinned response to sperm limitation and restricted gene flow

D.; Marine Biological Association of the UK; current address: Danish Institute for Fisheries Research, Charlottenlund, Denmark; Marine Biological Association of the UK: Polyembryony in spermcast simultaneous hermaphrodites: a twinned response to sperm limitation and restricted gene flow ? Polyembryony, the splitting of a single sexually produced […]
Marine dispersal patterns in Hawaii a casestudy of tubesnails with differing developmental modes
FAUCCI, A.; HADFIELD, M.G.; Univ. of Hawaii, Honolulu: Marine dispersal patterns in Hawaii: a casestudy of tubesnails with differing developmental modes Population genetic data can be used as an indirect measure of dispersal, because the variation in the distance that larvae are transported, and subsequently gene flow, result in characteristic genetic patterns. Vermetids or tubesnails […]
Intra- and inter-annual variation in the genetic diversity of a desert breeding anuran
CHAN, L. M.; Cornell University: Intra- and inter-annual variation in the genetic diversity of a desert breeding anuran. In the deserts of the southwestern United States many anurans breed explosively at ephemeral ponds with the onset of monsoon rains in dense aggregations lasting only one to four nights. Mating system characteristics, life history traits, and […]
Genetic comparisons between native Atlantic and invasive Pacific populations of the barnacle Chthamalus proteus
ZARDUS, J.D.*; HADFIELD, M.G.; University of Hawaii, Honolulu; University of Hawaii, Honolulu: Genetic comparisons between native Atlantic and invasive Pacific populations of the barnacle Chthamalus proteus. The Atlantic Barnacle (Chthamalus proteus) is a recent invader of the Pacific, first found in Hawaii in 1993. Faunal surveys suggest it became established in Hawaii between 10 and […]
Does gene flow maintain a maladaptive phenotype in a Batesian mimicry complex
HARPER, G. R.; University of North Carolina at Chapel Hill: Does gene flow maintain a maladaptive phenotype in a Batesian mimicry complex? Palatable species (mimics) may resemble toxic or venomous species (models) with which they co-occur and thus gain protection from predators. This phenomenon, termed Batesian mimicry, occurs in numerous plant and animal taxa. A […]
