THOMTON, J. D.*; TAMONE, S. L.; Univ. of Alaska, Fairbanks; Univ. of Alaska, Fairbanks: Measuring ecdysteroid levels to assess physiological state in Alaskan Dungeness crab populations Research on Dungeness crab (Cancer magister) has revealed a significant difference in the reproductive and growth cycles between populations of crabs in Alaska versus Washington, Oregon and California. Understanding […]

SWANSON, BO; GIBB, AC; LANDELS, C; Northern Arizona University; Northern Arizona University; Northern Arizona University: Kinematics of aquatic and terrestrial escape responses in mudskippers: Does the same morphology produce a similar behavior across different environments? Escape responses in fishes are rapid, often reflexive, behaviors that are critical for avoiding predators. Amphibious fishes are unusual in […]

HENRY, H.T.*; MARSH, R.L.; ELLERBY, D.J.; Northeastern University, Boston, MA; Northeastern University, Boston, MA; Northeastern University, Boston, MA: Jumping performance of guinea fowl Jumping performance has been studied in a variety of animals that are specialized for jumping. Although generally not considered specialized jumpers many birds must use powerful jumps routinely preparatory to flight. We […]

CROTWELL, P.L.*; MABEE, P.M.; Univ. South Dakota, Vermillion; Univ. South Dakota, Vermillion: Joints, co-option, and functional approaches in late-stage zebrafish Significant evolutionary changes in morphology are frequently manifested late in development. What is considered �late� in molecular developmental biology is defined in part by molecular genetic tools available to test gene function. Zebrafish researchers who […]
