Meeting Abstract S2.2-2  Saturday, Jan. 4 11:00  Nutritional Stress and the Evolution of Sexual Ornamentation: A Life History Perspective MOREHOUSE, N.I.; University of Pittsburgh nim@pitt.edu Nutritional stress is one of the most pervasive challenges that organisms face, with strong evolutionary leverage on all aspects of organismal life histories. Recent attention has focused on how sexual ornaments respond […]

Meeting Abstract S2.2-3  Saturday, Jan. 4 11:30  Mechanisms of Honest Signaling in Condition Dependent Growth in Exaggerated Traits LAVINE, L.C.*; EMLEN, D. J.; DUKE, A.; WARREN, I.A.; GOTOH, H.; Washington State University; University of Montana; University of Montana; University of Bristol; Washington State University lavine@wsu.edu Many male animals wield ornaments or weapons of exaggerated proportions. These traits […]

Meeting Abstract S2.1-1  Saturday, Jan. 4 08:00  Effects of developmental stress on a suite of physiological and behavioural traits in the zebra finch. CAREAU, V; BUTTEMER, WA; BUCHANAN, KL*; Deakin University; Deakin University; Deakin University kate.buchanan@deakin.edu.au Developmental pathways are shaped by evolution and may lead to defined suites of metabolic, behavioural, and life-history traits. Recent data suggest […]

Meeting Abstract S2.1-3  Saturday, Jan. 4 09:00  Developmental stress, song learning and cognition PETERS, S.*; SEARCY, W.A.; NOWICKI, S.; Duke University; University of Miami; Duke University speters@duke.edu The evolution of enhanced cognitive ability has sometimes been attributed to sexual selection. An association between male mating success and cognitive ability could arise either through male-male competition or through […]

Meeting Abstract S2.1-4  Saturday, Jan. 4 09:30  Developmental Stress, Condition, and Sexually Selected Traits in Song Sparrows MACDOUGALL-SHACKLETON, SA*; MACDOUGALL-SHACKLETON, EA; SCHMIDT, KL; KUBLI, SP; Univ Western Ontario, London, Canada smacdou2@uwo.ca Sexual selection theory posits that ornaments and displays reflect signaler condition, which in turn is affected by both recent and developmental conditions. Moreover, developmental conditions can […]

Meeting Abstract S2.3-3  Saturday, Jan. 4 14:30  Cellular respiration: the nexus of stress, condition, and ornamentation HILL, G. E.; Auburn Univ. ghill@acesag.auburn.edu Current theory suggests that females benefit by choosing highly ornamented males as mates because ornamentation is an honest signal of male condition. Empirical studies on a diversity of vertebrates and invertebrates have demonstrated associations between […]

Meeting Abstract S1.3-4  Saturday, Jan. 4 15:00  Epigenetics in Ecotoxicology HEAD, JA*; BASU, N; McGill University; McGill University niladri.basu@mcgill.ca An enormous amount of biomedical research has been focused on epigenetics in recent years. This wave is just beginning to hit the field of ecotoxicology, and the potential is exciting. The concepts behind epigenetics will generate ideas in […]

Meeting Abstract S1.2-2  Saturday, Jan. 4 10:30  Epigenetics in Cardiovascular Development HO, D.H.; Georgia Regents University, Augusta dho@gru.edu The field of epigenetics has gained much attention in the past few decades due to the fact that, in many instances, epigenetic processes outweigh direct genetic processes in the manifestation of aberrant phenotypes. Maternal effects, or the influences of […]

Meeting Abstract S1.3-1  Saturday, Jan. 4 13:30  Epigenetics and Species Divergence KELLER, TE; ZENG, J; MENDIZABAL, I; YI, SV*; Georgia Institute of Technology soojinyi@gatech.edu An important aspect of epigenetic inheritance is its pliability in response to changing signals from cellular environments. As such epigenetic modifications exhibit developmental- and cell type specific patterns that may underlie differentiation as […]

Meeting Abstract S1.1-1  Saturday, Jan. 4 08:00  Epigenetics and Organismal Biology BURGGREN, W. W.; University of North Texas burggren@unt.edu Epigenetics as a focus for biological studies has increasing exponentially over the decades since the introduction of this concept by Conrad H. Waddington in 1942. Yet, the broad incorporation of epigenetic theory and practice into experimental paradigms for […]
