Meeting Abstract P1.117  Sunday, Jan. 4  Chorioallantoic Membrane Vascular Function of the Embryonic Domestic Chicken (Gallus gallus) ALVINE, T*; CROSSLEY II, DA; University of North Dakota; University of North Dakota travis.alvine@und.edu Vascular function and regulation is poorly understood in most fetal/embryonic vertebrates. Given the complexity of the vascular tree in developing animals, specifically the presence of the […]

Meeting Abstract P1.48  Sunday, Jan. 4  Chewing Rate Allometry Requires Natural Selection GERSTNER, GE; University of Michigan geger@umich.edu Mammalian chewing is produced by brainstem circuits called central pattern generators, which can be functionally subdivided into burst-generating neurons and a central timing network (CTN). The CTN generates a rhythm that sets chewing rate. Chewing rate scales allometrically to […]

Meeting Abstract P1.75  Sunday, Jan. 4  Characterization of a Photoperiodically Regulated Protein from a Woodroach. WASSMER, Gary; Bloomsburg University of Pennsylvania gwassmer@bloomu.edu The woodroach, Parcoblatta pennsylvanica, is one of the few species of roach that is able to overwinter at subfreezing temperatures. As winter approaches, the growth rate of the insects slows and molting ceases. Laboratory and […]

Meeting Abstract P1.4  Sunday, Jan. 4  Breeding behavior in Prothonotary Warblers: Is food availability the key? MOORE, JR*; WALTERS, JR; MOORE, IT; Virginia Tech s2jrmoor@vt.edu Global climate change has resulted in the advancement of many phenological events in the spring such as budburst, insect emergence, and reproductive behavior of many birds. A long-term study of the Prothonotary […]

Meeting Abstract P1.5  Sunday, Jan. 4  Breeding and molt in Neotropical bird communities ECHEVERRY-GALVIS, M.A.; Princeton University mechever@princeton.edu The temporal regulation of key events, such as molt and reproduction in the life cycle of individual birds requires highly sensitive internal mechanisms that can respond to variations in environmental conditions. For most tropical high-altitude species little information is […]

Meeting Abstract P1.155  Sunday, Jan. 4  Are the immune systems of tropical birds glucocorticoid resistant? ALAM, J. L.*; LIEBL, A.L.; MARTIN, L.B.; FOKIDIS, H.B.; University of South Florida; University of South Florida; University of South Florida; Arizona State University jalam@mail.usf.edu Corticosterone alters immune function, but its effects vary depending on magnitude and duration, immune response characterized, species […]

Meeting Abstract P1.168  Sunday, Jan. 4  Arboreal Habitat Structure Affects the Choice of Routes by Rat Snakes HAMILTON, R.A.*; JAYNE, B.C.; University of Cincinnati hamiltr4@email.uc.edu Recent studies of arboreal vertebrates, including snakes, have found that the speed and difficulty of movement may be affected by: 1) the diameter and incline of individual branches, 2) the clutter and […]
