Meeting Abstract 15-8  Saturday, Jan. 4 11:45 – 12:00  Nectary size is a pollination syndrome trait in Penstemon KATZER, AM*; WESSINGER, CA; HILEMAN, LC; University of Kansas a681k477@ku.edu Individual trait adaptation can influence the evolution of complex phenotypes such as floral pollination syndromes. In Penstemon, hummingbird-adapted flowers have evolved many times from bee-adapted ancestors. We examined the […]

Meeting Abstract 15-3  Saturday, Jan. 4 10:30 – 10:45  From satellites to sequences: investigating drought adaptive life history evolution in plants MONROE, JG*; MCKAY, JK; Max Planck Institute for Developmental Biology; Colorado State University greymonroe@gmail.com http://greymonroe.github.io Explaining variation in life history strategies has been a central challenge of ecology and organismal biology for at least 250 years. […]

Meeting Abstract 15-6  Saturday, Jan. 4 11:15 – 11:30  Evolution of the integument and its implication in seed plant evolution. ZUMAJO-CARDONA, C*; AMBROSE , BA; The New York Botanical Garden; The Graduate Center-CUNY; The New York Botanical Garden czumajo@nybg.org Gene duplication plays a decisive role in organismal diversification and the appearance of novel structures. One of these […]

Meeting Abstract 15-2  Saturday, Jan. 4 10:15 – 10:30  A new perspective on ecological prediction reveals limits to climate adaptation in a temperate tree species BLUMSTEIN, MB*; RICHARDSON, AR; WESTON, D; ZHANG, J; WELLINGTON, M; HOPKINS, R; Harvard University, Cambridge; Northern Arizona University, Flagstaff; Oak Ridge National Laboratory, Oak Ridge; Oak Ridge National Laboratory, Oak Ridge; Oak […]

Meeting Abstract 15-5  Saturday, Jan. 4 11:00 – 11:15  A global molecular phylogeny of chromosomal evolution in wild onions (Allium, Amaryllidaceae) BABIN, CH*; BELL, CD; University of New Orleans; University of New Orleans chbabin@uno.edu Polyploidy, the event of increasing nuclear chromosomes, is believed to be a significant driver of diversification among land plants. Mechanisms of chromosome number […]

Moore, M.C.*; Painter, D.; Woodley, S.K.; Lacy, E.L.; Jennings, D.H.; Wikelski, M.: Neuroendocrine mechanisms of alternative male reproductive tactics in marine iguanas Alternative male phenotypes often differ as much in appearance and behavior as do males from females. These extreme examples of within-sex variation are good models to examine neuroendocrine bases of such variation. The […]

Mendon�a, M. T.: Effects of temperature, testosterone, and flutamide on mating in male big brown bats Male big brown bats exhibit a dissociated pattern of reproduction. They mate in the late fall and throughout the winter upon periodic arousal from hibernation when testosterone (T) is basal and gonads are regressed. In previous experiments, males mated […]

LOVERN, M.B.*; MCNABB, F.M.A.; JENSSEN, T.A.: Developmental effects of testosterone on behavior in male and female green anole lizards. This study addressed the role of testosterone (T) in the development of sexually dimorphic behavior in the green anole lizard, Anolis carolinensis. We described the developmental pattern of endogenous T concentrations, and determined the behavioral effects […]

WOODLEY, S.*; PAINTER, D.; MOORE, M.; WIKELSKI, M.: Daily rhythm of basal corticosterone levels is not synchronized with feeding activity in Marine Iguanas Basal plasma glucocorticoids (e.g., corticosterone (B)) levels follow a circadian rhythm. The rhythm can be entrained by photoperiod and food availability and functions in aspects of energy metabolism. Marine iguanas (Amblyrhynchus cristatus) […]
