Courtland, H.W-.*; Wright, G. M.; DeMont, M. E.: Physical Properties of Noncollagenous Lamprey Cartilages Morphological and biochemical studies have demonstrated that lamprey cartilages are different from other vertebrate cartilages in that their major structural components lack collagen and elastin. Notable biochemical and morphological variations even suggest that a family of noncollagenous matrix proteins comprises the […]

Moon, B.R.*; Urquhart, M.R.; Conley, K.E.: In vivo shortening in the superfast tailshaker muscle of rattlesnakes Sound-producing muscles typically contract at high frequencies with minimal shortening. The tailshaker muscle of western diamondback rattlesnakes (Crotalus atrox) contracts at frequencies of 20-100 Hz and has a constant energetic cost per twitch, but its extent of shortening is […]

FRANCIS, JR., A.W.*; TURINGAN, R.G.: Functional implications of asymmetrical feeding biomechanics in pleuronectiform fishes Flatfishes (Order Pleuronectiformes) differ from the generalized teleost morphology in that bilaterally symmetrical larvae metamorphose into bilaterally asymmetrical juveniles where one eye migrates to the opposite side of the head. The development of morphological asymmetry is expected to have profound consequences […]

SCHAR, D.W.*; KRUG, P.J.; ZIMMER, R.K.: The scent of danger: Chemical alarm signals and escape from cannibalism in newts Larvae of the California newt exhibit a chemically mediated anti-predator defense, demonstrating escape behavior and increased refuge use after detecting a cue from cannibalistic adults. Stream water collected near adults was tested in non-recirculating flow-through chambers, […]

COWART, J.D.: Sometimes It’s Good to Taste Bad: Palatability of Pteraster tesselatus (Echinodermata: Asteroidea) Adults and Offspring This study investigated secondary metabolites as chemical defenses in Pteraster tesselatus adults and offspring. Members of the Pterasteridae rapidly secrete copious amounts of mucus over their aboral surface when attacked. This mucus secretion is an effective anti-predator mechanism […]

MEAD, K.S.; WILEY, M.B.: How Do Benthic Crustaceans Trace Odor Plumes In Waves?: Integrating Fine-Scale Odor Structure With Animal Behavior. Like many crustaceans, stomatopods rely on their sense of smell to find food. Odors in their marine environment are present as filamentous plumes, which the animals have to trace to find the source. Stomatopods sample […]

RIORDAN, JR., T.J.; LINDSAY, S.M.*: Functional labeling of peripheral sensory cells in the spionid polychaete, Dipolydora quadrilobata Our integrated investigation of chemoreception in deposit-feeding polychaetes has identified and described putative sensory structures on the feeding palps of several spionid polychaete species and shown that chemical cues bound to glass beads stimulate feeding in the spionid […]

COHEN, J.H.*; FORWARD, JR., R.B.: Alteration of the shadow response in a larval crab by ctenophore kairomones Zoeal larvae of the estuarine crab Rhithropanopeus harrisii display negative phototaxis upon sudden decreases in light intensity. This photobehavior participates in a predator avoidance shadow response which functions in the avoidance of non-visually orienting surface predators such as […]

BOURNE, G.B.*; RUSSELL, A.P.; BARCLAY, R.M.R.; YEUNG, E.C.; Univ. of Calgary; Univ. of Calgary; Univ. of Calgary; Univ. of Calgary: Undergraduate Scientists as Content Specialists in the Grades1-6 Classroom In 1996, the Province of Alberta introduced a new science curriculum for grades one to six. Since few grades 1-6 teachers are trained science majors, there […]

MORSE, M.P.; Univ. of Washington, Seattle: “Science As A Way Of Knowing”: the Legacy of John A. Moore Scholarship in biology education has lost a great contributor with the passing of Dr. John A. Moore, Professor emeritus, University of California, Riverside. Member of the National Academies of Sciences, Moore’s research was in cellular and phenotypic […]
