Meeting Abstract 126.1  Tuesday, Jan. 7 13:30  Extending the U: Power estimates of Cliff Swallow low-speed flight and hovering in the field JACKSON, BE*; HEDRICK, TL; Skidmore College; Univ. North Carolina, Chapel Hill bjackson@skidmore.edu Most of our understanding of animal locomotion biomechanics comes from examining a limited set of behaviors in laboratory settings. For example, the costs […]

Meeting Abstract 126.5  Tuesday, Jan. 7 14:45  Don’t stop bee-weavin’: effects of wing wear on flight maneuverability in bumblebees MOUNTCASTLE, AM*; ALEXANDER, TM; COMBES, SA; Harvard University; Morgan State University; Harvard University mountcastle@fas.harvard.edu The wings of many insects experience cumulative and irreversible damage over the course of their lifespan, and this wear and tear can impose significant […]

Meeting Abstract 126.6  Tuesday, Jan. 7 15:00  Diversity and functional consequences of reducing synovial joints in bat wings BAHLMAN, J*; LIPPE, H; BREUER, K; SWARTZ, S; University of British Columbia; Brown University; Brown University; Brown University batman@zoology.ubc.ca Bat wings, like other mammalian limbs, contain many joints within the digits.

Meeting Abstract 125.5  Tuesday, Jan. 7 15:00  Testosterone at the Top of the World: Disparate hormone-behavior interrelationships between two high-arctic breeding populations of Lapland Longspurs (Calcarius lapponicus) ASHLEY, N.T.*; WINGFIELD, J.C.; Western Kentucky University; University of California, Davis noah.ashley@wku.edu Interrelationships between testosterone and aggression are dynamic and change in relation to life cycles even in polar environments […]

Meeting Abstract 125.1  Tuesday, Jan. 7 14:00  Shift in a life history trade-off linked with change in hormonal cross-talk ABOLINS-ABOLS, M*; KETTERSON, E D; Indiana University, Bloomington; Indiana University, Bloomington mabolins@indiana.edu Perhaps the most fundamental life history trade-off is that between reproduction and self-maintenance. This trade-off is mediated by the interaction of two major endocrine systems, the […]
