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 […]

Evolution of the Reproductive System of Urodasys (Gastrotricha, Macrodasyida)
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. In particular, species of Macrodasyida possess an array of accessory reproductive organs that function in sperm transfer and receival, but […]
Evolution of the LGR hormone receptor gene family in metazoans
Meeting Abstract P3.66 Sunday, Jan. 6 Evolution of the LGR hormone receptor gene family in metazoans AZOFEIFA, J.G.; CHAPPELL, P.; WEIS, V.M.; SCHWARZ, J.A.*; Vassar College; Oregon State University; Oregon State University; Vassar College joschwarz@vassar.edu Cnidarians exhibit cyclical patterns of gametogenesis and spawning, but it is not clear which genes play roles in establishing and controlling coral […]
Evolution of Rostrum Shape Variation in Mantis Shrimp
Meeting Abstract P3.85 Sunday, Jan. 6 Evolution of Rostrum Shape Variation in Mantis Shrimp STEVES, I.D.*; WRIGHT, M.L.; CALDWELL, R.L.; University of California, Berkeley; University of California, Berkeley; University of California, Berkeley isteves@berkeley.edu Widespread in tropical waters, mantis shrimp rely on their powerful raptorial appendages and keen eyesight to smash or spear their prey. Examined in isolation, […]
Evidence that octocorals are increasing in population density in the Caribbean
Meeting Abstract P3.58 Sunday, Jan. 6 Evidence that octocorals are increasing in population density in the Caribbean LENZ, E.A.*; EDMUNDS, P.J.; California State University, Northridge ealenz@gmail.com Coral reefs have long been valued as the most diverse marine ecosystem in the world, but their persistence is now threatened by multiple disturbances. In contrast to the high sensitivity of […]
Evaluating naturalized populations of western mosquitofish, Gambusia affinis, in the Verde River watershed for biomarkers of endocrine disruption
Meeting Abstract P3.30 Sunday, Jan. 6 Evaluating naturalized populations of western mosquitofish, Gambusia affinis, in the Verde River watershed for biomarkers of endocrine disruption HEALY, F.*; PARK, D.; BERGAMINI, R.; DANIELS, K.; PROPPER, C.R.; Northern Arizona Univ., Flagstaff fh52@nau.edu Invertebrate and vertebrate aquatic organisms exhibit a number of responses to xenobiotics, making them excellent bioindicators of environmental […]
Evaluating models of locomotion dynamics What complexity is adequate
Meeting Abstract P3.200 Sunday, Jan. 6 Evaluating models of locomotion dynamics: What complexity is adequate? HASANEINI, SJ; BERTRAM, JEA*; Univ. of Calgary, Calgary; Univ. of Calgary, Calgary jbertram@ucalgary.ca One approach to understanding biological legged locomotion is to use theoretical mechanical models as a test bed to evaluate theories of why humans and animals move as they do, […]
Establishing Antennule Flick Rate as an Assay for Odor Detection in Lobsters
Meeting Abstract P3.15 Sunday, Jan. 6 Establishing Antennule Flick Rate as an Assay for Odor Detection in Lobsters CLEMENTS, R*; RYCROFT, N; ATEMA, J; Boston University; Boston University; Boston University reenac@bu.edu Olfactory cues are important sources of information for marine organisms. The major odor detection organ for lobsters are the antennules. Aesthetasc sensilla on these antennules process […]
