Sex steroids and cortisol in male bluegill sunfish Correlations with reproductive tactic and stage of parental care
KNAPP, R.*; NEFF, B.D.; Univ. Oklahoma, Norman; Univ. Western Ontario, London, Canada: Sex steroids and cortisol in male bluegill sunfish: Correlations with reproductive tactic and stage of parental care Across vertebrates, androgens and glucocorticoids influence behavior and mediate responses to environmental stimuli, especially with respect to reproductive behavior and function. We are investigating how these […]

Parasite removal and its impact on behavior and reproduction in a social African ground squirrel
WATERMAN, J.M.*; HILLEGASS, M.A.; University of Central Florida, Orlando; University of Central Florida, Orlando: Parasite removal and its impact on behavior and reproduction in a social African ground squirrel. In the social species of ground-dwelling sciurids, females live in cohesive, matrilineal social groups. There are many suggested benefits of such cohesive groups, yet in some […]
Mechanisms for sex recognition in the big brown bat potential use of pheromones and ultrasonic vocalizations
MENDON�A, MT; SCHMAEMAN, CN; GRILLIOT, ME; Auburn University, Auburn, AL: Mechanisms for sex recognition in the big brown bat: potential use of pheromones and ultrasonic vocalizations A variety of studies in bats have demonstrated the use of pheromones for mother-young recognition, roost mate recognition, and male-male recognition in harem systems. Additionally, the use of ultrasonic […]

Economy of Mate Attraction in the Cassin’s Finch
SOCKMAN, KW; SEWALL, KB; BALL, GF; HAHN, TP; Univ. of North Carolina, Chapel Hill; Univ. of California, Davis; Johns Hopkins Univ., Baltimore; Univ. of California, Davis: Economy of Mate Attraction in the Cassin’s Finch Mate attraction can be costly. Thus, individuals should modulate it according to its probable benefits. Specifically, individuals should modulate mate-attraction efforts […]
Why are there so many calanoid copepods in temporary ponds of southeastern North America
TAYLOR, B.E.; DEBIASE, A.E.; Univ. of Georgia, SREL, Aiken; Univ. of Georgia, SREL, Aiken: Why are there so many calanoid copepods in temporary ponds of southeastern North America? At least fourteen species of calanoid copepods are known from temporary ponds on the Coastal Plain in South Carolina, USA, and additional species have been reported elsewhere […]
What determines lipid content in copepods preparing for long-term dormancy
WILLIAMS, Judith L.; Univ. of Southern Miss Gulf Coast: What determines lipid content in copepods preparing for long-term dormancy? The storage of lipids prior to dormancy is a widespread phenomenon in animals that diapause or hibernate. Lipid class and fatty acid content are highly variable, even within members of the same genus. Copepods undergo long […]
