Allometry of Hematological Parameters in Birds A Phylogenetic Approach
Meeting Abstract P3.43 Jan. 6 Allometry of Hematological Parameters in Birds: A Phylogenetic Approach WAGNER, E.C.*; WILLIAMS, T.D.; Simon Fraser University ewagner@sfu.ca The allometric scaling of metabolic rate across animal species has long been a subject of interest in comparative biology. Our objective here is to provide a functional explanation for this general pattern in birds by […]
Aggression in female dark-eyed juncos (Junco hyemalis) a role for progesterone
Meeting Abstract P3.139 Jan. 6 Aggression in female dark-eyed juncos (Junco hyemalis): a role for progesterone? JAWOR, Jodie*; KETTERSON, Ellen; Indiana University, Bloomington; Indiana University, Bloomington jodie.jawor@usm.edu In female mammals, progesterone (P) can influence sexual receptivity, maternal, and intrasexual aggression. Less is known about the role of P in female birds. Previous studies in dark-eyed juncos (Junco […]

A comparison of methods for collecting exhaled breath from birds for stable isotope analysis
Meeting Abstract P3.126 Jan. 6 A comparison of methods for collecting exhaled breath from birds for stable isotope analysis HATCH, K.A.; WU, A.C.*; Brigham Young University; Brigham Young University alexwu00@yahoo.com Stable isotope analysis is becoming a widely used technique in animal physiology and ecology. Usually muscle or liver tissue, hair or feathers are used for diet and […]
A biophysical model of the reflexive startle response interaction of Mauthner cells with the CPG
Meeting Abstract P3.76 Jan. 6 A biophysical model of the reflexive startle response: interaction of Mauthner cells with the CPG KUNEC, S A*; ROOT, R G; Worcester State College; Lafayette College stephen.kunec@worcester.edu One of the most primitive behaviors of vertebrates is the reflexive startle response. The interaction between Mauthner cells and the central pattern generator (CPG) lies […]

Disrupting […]
A Science Mentoring Model for Partnerships Between Graduate Research Communities and Public School Classrooms
Meeting Abstract P3.97 Jan. 6 A Science Mentoring Model for Partnerships Between Graduate Research Communities and Public School Classrooms MOREHOUSE, Nathan I.*; DAVIS, Jonathan R.; Arizona State University; Arizona State University nmorehouse@asu.edu A number of signs indicate a waning in student interest in secondary and post-secondary science education. This trend has spurned a call for changes, both […]
