Meeting Abstract 57.3  Thursday, Jan. 5  The relationship between insulin-like growth factor-1 and life history across Mammalia SWANSON, E.M.*; DANTZER, B.; Michigan State University; Michigan State University eliswanson@gmail.com Life history traits describe parameters associated with growth, reproduction and survival. Life history variation is a hallmark of biological diversity, yet persistent patterns of variation are apparent among life […]

Meeting Abstract 57.2  Thursday, Jan. 5  The insulin-like growth factor axis as a mediator of life history trade-offs ADDIS, E.A.*; SCHWARTZ, T.S; REDING, D.M.; PALACIOS, M.G.; BRONIKOWSKI, A.M.; Iowa State University addis@iastate.edu Classic life-history theory predicts trade-offs between the lifetime fecundity and lifespan of an individual. However, little is know about the mechanisms that control these trade-offs. […]

Meeting Abstract 57.5  Thursday, Jan. 5  Rapid evolution of sex frequency selected by requirement for dormancy and hydroperiod adaptation SMITH, H.A.*; SNELL, T.W.; Georgia Institute of Technology hilary.smith@gatech.edu In many cyclical parthenogens that alternate between asexual and sexual reproduction, dormant stages produced by the sexual generation allow survival in ephemeral habitats. For example, in monogonont rotifers an […]

Meeting Abstract 57.1  Saturday, Jan. 5  Of Lice and Lemurs: Personality Traits and Parasite Dynamics in Wild Brown Mouse Lemurs Microcebus rufus ZOHDY, S*; KEMP, A.D.; TECOT, S; WRIGHT, P.C. ; JERNVALL, J; Emory University; University of Texas, Austin; University of Arizona; Stony Brook University; University of Helsinki sarah.zohdy@emory.edu Animal personality traits have the potential to influence […]

Meeting Abstract 57.3  Saturday, Jan. 5  Maternal predation risk induces transgenerational behavioral plasticity in a parthenogenetic insect KEISER, C.N.*; MONDOR, E.B.; University of Pittsburgh, PA. Georgia Southern University, Statesboro, GA; Georgia Southern University, Statesboro, GA cnk21@pitt.edu It is becoming increasingly evident in many organisms that cues of immediate and latent predation risk in one generation can induce […]

Meeting Abstract 57.5  Saturday, Jan. 5  Food supplementation of urban and rural sparrows: effects on corticosterone, weight, and territorial aggression FOLTZ, S. L.*; DAVIS, J. E.; ROSS, A. E.; ROCK, R. P.; MOORE, I. T.; Virginia Tech; Radford University; Virginia Tech; Virginia Tech; Virginia Tech sarahf8@vt.edu Urban areas are novel habitats that present animals with new challenges […]

Meeting Abstract 57.4  Saturday, Jan. 5  Behavioral plasticity mediates life history trade-offs in response to habitat disturbance WILLIAMS-SIEG, K. A.*; MILES, D. B.; Ohio University kw114105@ohio.edu Environmental variation is known to induce trade-offs, which requires shifts in energy allocation among behaviors involved in reproduction, parental care and self-maintenance, thereby affecting reproductive success and survival. We examined behavioral […]
