Meeting Abstract P1.152 Wednesday, Jan. 4 Geographic variation in maternal effects across the breeding range of the tree swallow (Tachycineta bicolor) FORSMAN, A.M.*; PAITZ, R.T.; Cornell University; Illinois State University amf226@cornell.edu During the process of egg-formation, hormones and immune compounds accumulate in the developing yolk and subsequently influence offspring development. Maternally derived steroids such as testosterone have […]

Genetics and color development in a rare melanized and pterin-less morph of a North American lizard (Sceloporus)
Meeting Abstract P1.102 Wednesday, Jan. 4 Genetics and color development in a rare melanized and pterin-less morph of a North American lizard (Sceloporus) NYGAARD, K.R.*; HUND, A.K.; RAND, M.S.; Carleton College, Northfield, MN; Carleton College, Northfield, MN; Carleton College, Northfield, MN mrand@carleton.edu In certain Colorado populations, male prairie lizards (Sceloporus consobrinus) exhibit one of three discrete chin-color […]
Further Investigation of the Effects of Putative Neurotransmitters on the Body Wall of Lumbricus terrestris
Meeting Abstract P1.166 Wednesday, Jan. 4 Further Investigation of the Effects of Putative Neurotransmitters on the Body Wall of Lumbricus terrestris KRAJNIAK, K*; NEAL, M; Southen IL Univ. Edwardsville; Southern IL Univ. Edwardsville kkrajni@siue.edu Previous studies have suggested that putative neurotransmitters modulate body wall contractions of L. terrestris. To investigate body wall modulation, a dorsal strip of […]
Functional Characterization of Calsequestrin from the Eurythermal Killifish, Fundulus similis
Meeting Abstract P1.162 Wednesday, Jan. 4 Functional Characterization of Calsequestrin from the Eurythermal Killifish, Fundulus similis GROVE, TJ*; FORT, TJ; Valdosta State University; Valdosta State University tjgrove@valdosta.edu Calsequestrin (CSQ) is a calcium-binding protein in sarcoplasmic reticulum (SR) that undergoes dramatic conformational changes, changing from a random coil at low Ca2+ levels in SR during muscle contraction to […]
Frontal Sinus Morphology in Arctoid Carnivorans
Meeting Abstract P1.94 Wednesday, Jan. 4 Frontal Sinus Morphology in Arctoid Carnivorans CURTIS, Abigail A.*; LAI, George; VAN VALKENBURGH, Blaire; Univ. of California, Los Angeles abigailacurtis@gmail.com Frontal sinuses are one of four mammalian paranasal sinuses that form when nasal epithelium escapes the nasal chamber and invades surrounding bones including the maxilla, sphenoid, ethmoid, and frontal. Sinuses appear […]
Force enhancement of soleus muscles from mdm mice
Meeting Abstract P1.155 Wednesday, Jan. 4 Force enhancement of soleus muscles from mdm mice FUQUA, RD*; MONROY, JA; NISHIKAWA, KC; Northern Arizona University rdf2@nau.edu When muscles are stretched actively, tension increases and settles at a steady state that is well above isometric force. The mechanism underlying this behavior, termed force enhancement, remains poorly understood. In this study, […]
Flying high body size, flight performance, and vertical stratification of orchid bee communities in tropical rainforests
Meeting Abstract P1.72 Wednesday, Jan. 4 Flying high: body size, flight performance, and vertical stratification of orchid bee communities in tropical rainforests CRALL, J.D.*; COMBES, S.A.; Harvard University; Harvard University jcrall@oeb.harvard.edu Forests are complex three-dimensional environments, characterized by significant gradients of wind speed and turbulence from the forest floor to the canopy. Such complexity is frequently accompanied […]
Fish out of water Evaluating the use of substrate during terrestrial excursions
Meeting Abstract P1.116 Wednesday, Jan. 4 Fish out of water: Evaluating the use of substrate during terrestrial excursions ALUCK, R/J*; WARD, A/B; Adelphi University; Adelphi University robertaluck@mail.adelphi.edu Vertebrate body shapes are extremely diverse ranging from spheroidal to highly elongate. In fishes, body elongation is due primarily to changes in the axial skeleton. Most frequently, elongate fish species […]
Fall migration is associated with changes in neurogenesis in red-sided garter snakes (Thamnophis sirtalis)
Meeting Abstract P1.172 Wednesday, Jan. 4 Fall migration is associated with changes in neurogenesis in red-sided garter snakes (Thamnophis sirtalis) MAINE, A.R.*; POWERS, S.D.; LUTTERSCHMIDT, D.I.; Portland State University, Oregon; Portland State University, Oregon; Portland State University, Oregon d.lutterschmidt@pdx.edu Seasonal rhythms in physiology and behavior are often associated with changes in brain markers, including the generation of […]
