Meeting Abstract 32-7  Saturday, Jan. 4 15:00 – 15:15  Is a novel marker of oxidative damage linked to aerobic scope and flying performance in birds exposed to crude oil? GOODCHILD, CG*; DURANT, SE; Oklahoma State University; University of Arkansas christopher.goodchild@okstate.edu Birds externally exposed to crude oil have impaired flying performance due to crude oil damaging the microstructure […]

Meeting Abstract 32-2  Saturday, Jan. 4 13:45 – 14:00  Energy expenditure of cage activity versus wheel running in deer mice DOLAN, JE*; MUSIAL, NA; HAMMOND, KA; UC, Riverside; UC, Riverside; UC, Riverside jdola001@ucr.edu In the lab, mice are often kept in cages seemingly without any way to exercise, thus restricting their voluntary energy expenditure. Because of this […]

SWIDERSKI, D.L.: Diversity of patterns of variation in the lower jaw of tree squirrels. Squirrels have a reputation for being morphologically conservative, and some investigators explicitly argue that most evolution of squirrel morphology can be described by an allometric trend. Most previous morphometric studies of squirrels have used sets of distance measurements. Such studies are […]

Theodor, J. M.*; Janis, C. M.; Boisvert, B.: Camelid foot morphology and the evolution of the pacing gait Among wild mammals, camels are unique in their use of a running pacing gait instead of a trot. Extant camelids are characterized by features unusual among artiodactyls: their feet are secondarily digitigrade, with a broad, flat pad […]

WHIDDEN, H.P.*; WOODS, C.A.: Assessment of sexual dimorphism in the Antillean insectivoran Nesophontes The Antillean insectivoran Nesophontes is known only from subfossil material from Cuba, Hispaniola, Puerto Rico, and the Cayman Islands. When the first Nesophontes species was described from Puerto Rico, specimens appeared to fall into 2 size classes, and this size variation was […]

HAUSSMANN,M.F.*; VLECK,C.M.; BRENNER,S.A.: Aging animals using telomere length – a novel approach. Field biologists often must work with animals for which there is no prior history. A physiological marker of an animal’s age would offer insight into how age and experience affect reproductive success and other life history parameters. The length of telomeres, theprotective caps […]

SANTINI, F.: Speciation in the Sea During this presentation I will review the recent literature on patterns of speciation that has been used by some authors to support the claim that vicariance is the dominant mode of speciation in vertebrates. This conclusion has been reached by applying flawed models of speciation to the study of […]
