MURDOCK, C.A.; WIBBELS, T.; University of Alabama at Birmingham: Chronology of expression for potential sex-determining genes during temperature-dependent sex determination. Temperature-dependent sex determination (TSD) has been observed in many species of reptiles. During TSD egg incubation temperatures influence the sex determination during a critical period of embryonic development (i.e., temperature-sensitive period or TSP), which coincides […]

MEAD, K. S.; Denison University: Blood Sugar And Exercise: Inquiry-Based Laboratory Exercises About Homeostasis. Three groups of undergraduate physiology students designed and carried out related laboratory experiments that examined the effect of exercise on blood glucose. All experiments used Freestyle glucometers to monitor blood glucose levels in normal, non-diabetic college students. The first set of […]

DAVIS, H.*; DIAL, K. P.; Univ. of Montana, Missoula; Univ. of Montana, Missoula: Bipeds Ascending: Avian Locomotor Performance During Incline Running. Recent work suggests that some bipedal ground birds use their forelimbs in novel ways to increase escape performance up steep inclines (Dial 2003). To better understand how bipedal birds in general negotiate sloped terrestrial […]

VEAZEY LASSEIGNE, J; LANDRY, CA; LAFLEUR, JR, GJ; Nicholls State University, Thibodaux, LA: Biomarkers of oogenesis as molecular tools for conservation biology Louisiana is currently losing an acre of coastal wetlands every 30 minutes. To reverse this natural disaster, large-scale restoration activities are being proposed which will divert water and sediments from the Mississippi River […]

CARSIA, R.V.; JOHN-ALDER, H.B.*; UMDNJ School of Osteopathic Medicince, Stratford; Rutgers Univ., New Brunswick: Atrial Natriuretic Peptide (ANP) is a Negative Modulator of Adrenocortical Cell Function in Sceloporus undulatus (Eastern Fence Lizard) In mammals, ANP is a consistent suppressor of aldosterone secretion, but its effects on adrenal steroidogenic function in non-mammalian vertebrates are both stimulatory […]

LUCKENBACH, J/Adam; EARLY, Lea/W; BORSKI, Russell/J; ROWE, Ashlee/A; GODWIN, John; North Carolina State Univ., Raleigh: Aromatase: a functional biomarker for female differentiation in a teleost fish The Southern flounder (Paralichthys lethostigma) is a high-value teleost fish in which females grow faster and reach a larger adult body size than males. We have shown that Southern […]
