NEVITT, Gabrielle ; LEMA, Sean; Univ. of California, Davis; Univ. of California, Davis: Testing a new model for olfactory imprinting in salmon: Evidence for proliferation of olfactory receptor neurons in response to thyroid hormone. Salmon are famous for their ability to imprint and home to natal stream odors, yet the mechanisms driving olfactory imprinting remain […]

LOVERN, M.B.*; WADE, J.; Michigan State Univ., East Lansing; Michigan State Univ., East Lansing: Relationship among sex steroid levels in breeding female plasma, yolk, and embryonic tissue in green anole lizards Sex steroids have been documented in the egg yolks of numerous birds and reptiles, but why they are there remains an open question. Steroids […]

TUBERTY, S. R.; GLAS, P.S.; Appalachian State University, Boone, NC; The Citadel, Charleston, SC: Free Ecdysteroid Levels in Grass Shrimp Embryos Relate to Embryonic Envelope Elevation Ecdysteroids, the hormones responsible for stimulating arthropod molting, are secreted by Y-organs in eyestalks of adult crustaceans. Ecdysteroids have been identified in crab (Okazaki and Chang, 1991) lobster (Goudeau, […]

WILLIAMS, T.D. *; VEZINA, F.; KITAYSKY, A.S.; Simon Fraser University, Burnaby; Simon Fraser University, Burnaby; University of Washington, Seattle: Estradiol: a neglected hormone in maternal modification of offspring phenotype? Many current studies suggest that transfer of maternal steroid hormones to the developing embryo might play a role in non-genetic modification of offspring phenotype. However, to […]

RYAN, W.L.; Kutztown University of Pennsylvania: Using AmphibiaWeb as a Model for Guided Inquiry The recent discovery of declining amphibian populations and its correlation with various human activities is one of a number of environmentally sensitive issues to arise in the past decade. It can be difficult for students, particularly undergraduates, to investigate a problem […]

MYERS, Marcella J.; College of Saint Catherine: The Confidence to Use Confidence Intervals:Moving Students toward More Sophisticated Analyses As the result of much trial and error in the undergraduate classroom, I have become convinced that: 1) students require objective rules (statistics) to properly interpret their data, no matter how simple the experiment, 2) students learn […]

MORSE, M. Patricia; Univ. of Washington, Seattle: Teacher Scholar Partnerships: Civic Engagement for Undergraduate Biologists in K-12 Schools The Teacher Scholar Partnership (TSP) presents a model for partnerships in science and mathematics (S&M) education with the K-12 community. The primary focus is to draw the attention of undergraduate S&M majors to the rewards of working […]

BUTCHER, M.T.*; BERTRAM, J.E.A.; Florida State University; Florida State University: Newton�s Laws of Motion and jumping performance: A lab exercise investigating jump distance increases due to added hand-held weight. Learning is facilitated by both engaging students in the learning process and providing them with direct experience of the phenomena of interest. This biomechanics laboratory is […]
