Nuptial thief male spiders steal food from mating partners
Meeting Abstract 115.1 Saturday, Jan. 7 Nuptial thief: male spiders steal food from mating partners DANIELSON-FRANCOIS, A.*; DROBOT, Y.; University of Michigan – Dearborn; University of Michigan – Dearborn danfranc@umd.umich.edu Adult male spiders do not build webs. Once males molt to maturity, they wander in search of females to mate. For orb-weaving spiders, not building a web […]
Mating Status Drives Male-Female Interactions in a Polygynandrous Butterfly
Meeting Abstract 115.2 Saturday, Jan. 7 Mating Status Drives Male-Female Interactions in a Polygynandrous Butterfly WESTERMAN, E.L.*; MONTEIRO, A.; Yale University; Yale University erica.westerman@yale.edu Operational sex ratio (OSR) is one of the main factors driving mate selectivity and mating behavior. Though often considered stable for a given population, OSR may vary throughout the breeding season as mating […]
The link between stress and behavior in zebrafish is embryonic perturbation a factor
Meeting Abstract 114.5 Saturday, Jan. 7 The link between stress and behavior in zebrafish: is embryonic perturbation a factor? WIEDEBACK, B D*; OSWALD, M E; ROBISON, B D; University of Idaho; University of Notre Dame; University of Idaho bwiedeback@vandals.uidaho.edu It is well known that embryonic exposure to stress hormones can affect adult behavior in mammals. However, the […]

Is plasma corticosterone a useful biomarker of environmental degradation
Meeting Abstract 114.1 Saturday, Jan. 7 Is plasma corticosterone a useful biomarker of environmental degradation? WOODLEY, S.K.*; RICCIARDELLA, L.F.; Duquesne University; Duquesne University woodleys@duq.edu Amphibians are declining throughout the world due to many factors. One source of environmental degradation impacting amphibian populations in Pennsylvania is stream acidification. We asked whether sublethal exposure to acidified environments was associated […]
