BRANDENBURG, M.D.*; MILES, D.B.; Ohio University, Athens; Ohio University, Athens: Responses of Small Mammals to Deer Exclosures in Oak-Hickory Forest Small mammal communities of eastern deciduous forests provide a model system for evaluating how variables such as behavior, food availability, competition, and abiotic conditions structure communities. Several herbivorous mammals coexist in eastern forests: White-tailed deer […]

SABA, M.V.*; HORN, M.H.; California State University, Fullerton; California State University, Fullerton: Ontogeny of Diet and Trophic Position in Herbivorous and Carnivorous Prickleback Fishes (Stichaeidae): Dietary and Stable Isotope Analyses We examined gut contents and carbon (&delta13C) and nitrogen (&delta15N) signatures of four related, wild-caught, and experimentally-fed (high-protein animal diet) prickleback fishes as well as […]

BERGER, M.S.; University of Oregon, OIMB: Juvenile performance of the barnacle Balanus glandula along an estuarine gradient The acorn barnacle, Balanus glandula, has a wide intertidal distribution within the South Slough Estuary in Oregon that ranges from the oceanic mouth to approximately six kilometers upstream towards the riverine head of the estuary. Along this horizontal […]

REITZEL, A.R.*; DARLING, J.; Boston University; Boston University: Global population structure of the invasive salt marsh anemone Nematostella vectensis Nematostella vectensis is a euryhaline, burrowing anemone inhabiting estuarine sediments along the Atlantic, Gulf, and Pacific coasts of North America, as well as the southern and southeastern coasts of England. The species is currently listed as […]

CORBIN, Clay E; Bloomsburg University: Ecomorphological Concordance in North American and South African Flycatcher Communities In both the Old and New Worlds, independent clades of sit-and-wait insectivorous birds have evolved. These independent radiations provide an excellent opportunity to test whether the relationships between morphology and ecology are concordant. First, with canonical correlation analysis, I test […]

BUNKERS, J L; GOMES, F; REZENDE, E L; SALTZMAN, W; GARLAND, T Jr; Univ. of California, Riverside: Plasma Corticosterone of Mice Selectively Bred for High Voluntary Wheel Running: Levels at Rest and Following Restraint Stress The hypothalamic-pituitary-adrenal (HPA) axis is important in regulating energy metabolism and mediates responses to a broad range of stressors. Glucocorticoids […]

DERRICKSON, E.M.; Loyola College: Maternal protein intake during pregnancy and lactation determines milk composition in Mus musculus Both the quantity and quality of resources available to mammals can strongly influence growth and development of juveniles during the lactation period. Although the quantity of food has demonstrated effects on lactation and reproductive success, the effect of […]

OUFIERO, C.E.*; ANGILLETTA, M.J.; Indiana State Univ., Terre Haute: It�s not just the size; it�s what�s inside that counts: Female size, egg size, and egg composition in the lizard Sceloporus undulatus. Morphological constraints are thought to produce non-adaptive variation in egg size. For example, the size of a female�s pelvis may force her to produce […]

MARTIN, LB*; HASSELQUIST, D; WIKELSKI, MC; Princeton University; Lund University; Princeton University: Immune function complements life history in tropical and temperate House Sparrows Tropical passerine birds often lay small clutches, have long embryonic developmental periods, and high adult survival rates compared to related temperate species. Many ecological factors, particularly nest predation and food availability, have […]

HAZARD, L.C.*; NAGY, K.A.; MILES, D.; COSTA, D.; SINERVO, B.; Univ. of California, Santa Cruz; Univ. of California, Los Angeles; Ohio University; Univ. of California, Santa Cruz; Univ. of California, Santa Cruz: Field metabolic rate, stamina and survival of male lizards with alternative mating strategies Male side-blotched lizards (Uta stansburiana) in Los Banos, CA exhibit […]
