Meeting Abstract P3.174  Sunday, Jan. 6  Exogenous corticosterone reduces circulating testosterone but not courtship behavior in male zebra finches (Taeniopygia guttata) FERGUSON, S.M.*; LYNN, S.E.; University of Memphis; College of Wooster s.ferguson@memphis.edu Among vertebrates, environmental stressors can simultaneously activate the hypothalamo-pituitary-adrenal (HPA) axis, inhibit hypothalamo-pituitary-gonadal (HPG) axis activity, and alter reproductive behavior. For example, previous studies in […]

Meeting Abstract P3.100  Sunday, Jan. 6  Evolution of the Reproductive System of Urodasys (Gastrotricha, Macrodasyida) ATHERTON, S.*; HOCHBERG, R.; University of Massachusetts Lowell; University of Massachusetts Lowell sarah_atherton@student.uml.edu Gastrotrichs are microscopic, hermaphroditic invertebrates with complex reproductive systems.
