Did bat ancestors glide A phylogenetic approach
Meeting Abstract 28.1 Friday, Jan. 4 Did bat ancestors glide? A phylogenetic approach PADIAN, K.*; DIAL, K.P.; Univ. of California, Berkeley; Univ. of Montana, Missoula kpadian@berkeley.edu The predominant biological view of the evolution of flight is that it is preceded phylogenetically by a gliding stage. Support for this hypothesis has mainly rested on what is presumed to […]
Two closely related cichlids with divergent social systems differ in socially relevant behaviours and molecular pathways
Meeting Abstract 28.1 Saturday, Jan. 4 13:30 Two closely related cichlids with divergent social systems differ in socially relevant behaviours and molecular pathways O’CONNOR, CM*; MARSH-ROLLO, S; CORTZ GHIO, S; HICK, K; TAN, J; WONG, MYL; REDDON, AR; AUBIN-HORTH, N; BALSHINE, S; McMaster University; McMaster University; Universite Laval; McMaster University; McMaster University; University of Wollongong; McMaster University; […]
Oxidative Costs of Reproduction and the Evolution of Cooperative Breeding
Meeting Abstract 28.2 Saturday, Jan. 4 13:45 Oxidative Costs of Reproduction and the Evolution of Cooperative Breeding GUINDRE-PARKER, S.*; RUBENSTEIN, D.R.; Columbia University, NYC; Columbia University, NYC slg2154@columbia.edu For cooperative breeders where more than two individuals care for young, high costs of parental care may contribute to the evolution of this social behavior. This hypothesis has gone […]
Experimentally testing potential benefits of cooperative display in passerine bird
Meeting Abstract 28.3 Saturday, Jan. 4 14:00 Experimentally testing potential benefits of cooperative display in passerine bird JONES, M.A.; Florida State University majones@bio.fsu.edu Much of the research of understanding cooperative behaviors has focused on why helpers assist. There has been little attention to why the recipient of the help participates; the benefit is often assumed. Yet it […]
Collective learning and optimal consensus decisions in social animal groups
Meeting Abstract 28.4 Saturday, Jan. 4 14:15 Collective learning and optimal consensus decisions in social animal groups KAO, AB*; MILLER, N; TORNEY, C; HARTNETT, A; COUZIN, ID; Princeton University; Princeton University; Princeton University; Princeton University; Princeton University akao@princeton.edu Learning has been studied extensively in the context of isolated individuals. However, many organisms are social and consequently make […]
Unable to shift gears the loss of variable gearing in aged muscles
Meeting Abstract 28.1 Monday, Jan. 5 08:00 Unable to shift gears: the loss of variable gearing in aged muscles HOLT, NC*; DANOS, N; AZIZI, E; UC Irvine natalie.c.holt@gmail.com In pennate muscles, shortening of muscle fibers is accompanied by a change in their pennation angle. This fiber rotation can increase whole muscle shortening velocity for a given fiber […]
Titin function during in vitro cyclic movements
Meeting Abstract 28.5 Monday, Jan. 5 09:00 Titin function during in vitro cyclic movements MONROY, J.A.*; NISHIKAWA, K.C.; Denison University; Northern Arizona University monroyj@denison.edu The goal of predicting how muscle force changes during natural cyclic movements remains elusive. The sarcomeric protein, titin, has been suggested to play a role in a number of muscle properties that influence […]
Simulating titin’s role in force enhancement using the “winding filament hypothesis”
Meeting Abstract 28.8 Monday, Jan. 5 09:45 Simulating titin’s role in force enhancement using the “winding filament hypothesis” NISHIKAWA, K*; FUQUA, RD; HANSON, S; MONROY, JA; PACE, CM; Northern Arizona University; The Jackson Laboratories; Northern Arizona University; Denison University; Northern Arizona University kiisa.nishikawa@nau.edu We developed a “winding filament” hypothesis for muscle contraction that includes a role for […]
Passive force along the length-tension curve A role for titin
Meeting Abstract 28.3 Monday, Jan. 5 08:30 Passive force along the length-tension curve: A role for titin? PACE, CM*; MONROY, JA; NISHIKAWA, KC; Northern Arizona University; Denison University; Northern Arizona University Cinnamon.Pace@nau.edu When a muscle has been stretched during activation, the passive tension of the relaxed muscle is greater than after an isometric contraction at the stretched […]
