GIFFORD, M. E.**; LARSON, A.; Washington University, St. Louis; Washington University, St. Louis: Consequences of recent secondary contact between lineages of Ameiva chrysolaema in the Dominican Republic Historic climate fluctuations have been implicated as playing a significant role in structuring genetic variation within and between species. Repeated expansion and contraction of organismal ranges has has […]

Meeting Abstract 67.2 Jan. 7 Seasonal changes in the diet of a non-hibernating high-latitude rodent: the northern red-backed vole, Clethrionomys rutilus. BRENNAN, April M.*; VAN TETS, Ian G. ; University of Alaska Fairbanks; University of Alaska Anchorage ftamb@uaf.edu Rodents, such as lemmings and voles, which do not use hibernation and torpor, must choose foods that will enable […]
Physiological Consequences of Folic Acid in the Fruit Fly
Meeting Abstract 67.3 Jan. 7 Physiological Consequences of Folic Acid in the Fruit Fly BLATCH, S.A.*; HARRISON, J.F.; Arizona State Univ.; Arizona State Univ. sydella.blatch@asu.edu Folic acid is essential for DNA synthesis and methylation, a form of epigenetic regulation. Irregularities in folate metabolism have been linked with a host of diseases, but the mechanisms remain unclear. The […]
Food intake and its effects on life history in a parthenogenetic insect
Meeting Abstract 67.5 Jan. 7 Food intake and its effects on life history in a parthenogenetic insect ROARK, A.M.**; BJORNDAL, K.A.; Univ. of Florida, Gainesville; Univ. of Florida, Gainesville amroark@ufl.edu Changes in food availability throughout an animal�s lifetime can influence physiology and life history. In this study, we assessed the effects of various combinations of ad libitum […]
Changes in antioxidant production during chronic caloric restriction may affect susceptibility to intestinal parasites
