COOK, M.E.; MOORE, P.A.; Bowling Green State University; Bowling Green State University: The effects of the herbicide metolachlor on agonistic behavior in the crayfish Orconectes rusticus Previous research suggests that agricultural herbicides interfere with behavior, especially in impacting an animal�s ability to receive and respond to chemical stimuli. Aggressive interactions between animals are important in […]

The Thyroid Disrupting Effects of Ammonium Perchlorate Depend upon Environmental Iodide and Developmental Stage in Larval Xenopus Laevis
HU, F.; GENTLES, A.; GOLEMAN, W.L.; CARR, J.A.; Texas Tech Univ.; Texas Tech Unvi.; Texas Tech Univ.; Texas Tech Univ.: The Thyroid Disrupting Effects of Ammonium Perchlorate Depend upon Environmental Iodide and Developmental Stage in Larval Xenopus Laevis Ammonium perchlorate, a military and aerospace industry waste product, disrupts thyroid function and retards metamorphosis in laboratory […]
The Effects of the Common Pesticide Endosulfan on Behavior and the Stress Response in Bullfrogs (Rana catesbeiana)

The Effect of Reclaimed Wastewater on Western Mosquitofish (Gambusia affinis) Survivorship
SOMLEY, B.L.*; HORTIN, S.M.; PROPPER, C.R.; Bates College: The Effect of Reclaimed Wastewater on Western Mosquitofish (Gambusia affinis) Survivorship This study investigated the endocrine disrupting potential of reclaimed wastewater. We hypothesized that the wastewater treatment process may not have sufficiently removed all androgenic xenobiotics. Female western mosquitofish (Gambusia affinis) were utilized as bioindicators because they […]
The Depression of Oxygen Uptake in Blue Crabs in Response to Bacterial Challenge
HOLMAN, J.D.*; BURNETT, L.E.; BURNETT, K.G.; JORGENSEN, D.D.; Univ. of North Texas; College of Charleston; College of Charleston; Roanoke College: The Depression of Oxygen Uptake in Blue Crabs in Response to Bacterial Challenge We investigated the respiratory responses of the blue crab, Callinectes sapidus, to an injection of bacterial pathogen Vibrio sp. 90-69B3. Current results […]
Testosterone Correlates with Morph-type in the Behaviorally Polymorphic White-throated Sparrow (Zonotrichia albicollis)
SWETT, M. B.; BREUNER, C. W.; Univ. of Texas, Austin; Univ. of Texas, Austin: Testosterone Correlates with Morph-type in the Behaviorally Polymorphic White-throated Sparrow (Zonotrichia albicollis) The white-throated sparrow exhibits a unique genetic polymorphism that effects plumage and behavior in both sexes. Birds possessing a chromosomal inversion have brighter white stripes on their crown, are […]
Swimming in painted turtles testing kinematic similarity among members of a morphologically conservative lineage
ESPINOZA, N.R.*; BLOB, R.W.; Erskine College; Clemson University: Swimming in painted turtles: testing kinematic similarity among members of a morphologically conservative lineage. Use of representative species is widespread in evolutionary studies of locomotor diversity. Functional diversity is often expected in the context of morphological divergence among taxa, but what are the prospects for locomotor diversity […]
Swim Speed and Cholinesterase Activity in Organophosphate Exposed Anuran Tadpoles
WIDDER, P. D. *; HUSAK, J.F.; BIDWELL, J.R.; Oklahoma State University, Stillwater; Oklahoma State University, Stillwater; Oklahoma State University, Stillwater: Swim Speed and Cholinesterase Activity in Organophosphate Exposed Anuran Tadpoles A commonly used biomarker for exposure to organophosphate pesticides is cholinesterase (ChE) activity, however the ecological relevance of this parameter remains largely unexplored in anurans. […]
Storage protein levels in lubber grasshoppers are not regulated by juvenile hormone
HATLE, John D.; DING , Xiang; BARRY, Thomas O.; BORST, David W.; Univ. of North Florida; Illinois State Univ.; Illinois State Univ.; Illinois State Univ.: Storage protein levels in lubber grasshoppers are not regulated by juvenile hormone Hemolymph storage proteins (SPs), especially methionine-rich SPs, are negatively regulated by juvenile hormone (JH) in several insects. In […]
Starting an Undergraduate Field Research Program
ARMSTRONG, S.L.; MCKEOWN, J.P.; Millsaps College; Millsaps College: Starting an Undergraduate Field Research Program There are many opportunities for undergraduates to study abroad in a classroom setting or living with a local family, but biological field research is usually reserved for graduate students. In the summer of 2002, we began a successful undergraduate research program […]
