SKIBIEL, A.L.*; KATS, L.B.; VANDERGON, T.L.; Juniata College, Huntingdon, PA.; Pepperdine University, Malibu, CA.; Pepperdine University, Malibu, CA.: Microsatellite allele composition differs significantly between two populations of the California newt, Taricha torosa, in the Santa Monica Mountains. Coastal populations of the California newt, Taricha torosa appear to be in decline. Much of the coastal California […]

DETTAI, A.; LECOINTRE, G.; MNHN, Paris; MNHN, Paris: MetAcanthomorpha, a phylogeny-oriented database for acanthomorph morphology Acanthomorpha (Teleostei) is a wide clade currently divided in 329 families (for about 15 000 species). Relationships within acanthomorphs are not fully resolved, despite the fact that a great amount of morphological and molecular data has already been published, however […]

JONZ, M.G.*; NURSE, C.A.*; McMaster University, Hamilton, ON, Canada: Merkel-like cells of the zebrafish gill arch and oral epithelium The identity of receptors that line the buccal cavity and gill arches in fish sensitive to mechanical stimuli is unknown. Neurosecretory cells in these regions, similar in morphology to mechanoreceptive Merkel cells of higher vertebrates, have […]

TRIBLEHORN, J.D.*; YAGER, D.D.; Univ. of Maryland, College Park; Univ. of Maryland, College Park: Mantis auditory interneuron 501-T3 responses and the triggering of the evasive response during bat attack sequences. Bat vocalization parameters (such as pulse repetition rate-PRR and pulse duration-PD) change predictably as they approach and capture prey. A flying mantis could use these […]

DRENNAN, R.W.; MCCLARY, JR., M.; Fairleigh Dickinson University, Teaneck, NJ; Fairleigh Dickinson University, Teaneck, NJ: Low salinity does not control the distribution of barnacles in the tidal Hackensack River. The barnacles, Balanus improvisus, are found and were once found in sites in the tidal Hackensack River of New Jersey. Previous transplantation studies conducted in the […]

LANDELS, C.; GIBB, A.C.; Northern Arizona University; Northern Arizona University: Kinematics of the aquatic escape response in Periophthalmus argentilineatus: Do mudskippers “skip” underwater? Periophthalmus argentilineatus, also known as the mudskipper, is an amphibious fish species. Because members of this species are amphibious, they produce both aquatic escape responses (“C-starts”) and terrestrial ones (“skipping”) when fleeing […]

JOHNSEN, D.A.J.; WICKLER, S.J.; COGGER, E.A.; HOYT, D.F.; California State Polytechnic University, Pomona: Kinematics of the Walk-Trot Transition in Horses In humans, the transition from a walk to a run is correlated with changes in joint kinematics, in particular peak ankle angular velocity and peak ankle angular acceleration. Because the spring mass model describes both […]
