H�STAD, O.*; �DEEN, A.: Different avian color vision in predator and prey Birds see more than twice the number of colors compared to humans, and individual colors may appear very different, even to different bird species. We have developed a molecular marker that can be used for determining the type of color vision. The eyes […]

MCCRARY, S.P.; GONZALES, R.J.; SIMOVICH, M.A.: Correlation between Crustacean Fauna and Chemical Properties of Desert Dry Lakes at Edwards Air Force Base and 29 Palms Marine Base for Use in Management Planning. Temporary wetlands are disappearing across the world at an alarming rate. Our understanding of these systems is unfortunately limited because of their unpredictable […]

GAWLICKA, A.*; HORN, M.H; FREEMAN, C.T.; KIM, K.H.: Comparative ultrastructure of the intestinal epithelium in three species of atherinopsid fishes with different diets We explored possible diet-related specializations of the gut epithelium in stomachless fishes by comparing the surface area of the brush border and qualitative features of the absorptive cells in three closely related […]

KRIZ, M.A.*; RENO, P.L.; MCCOLLUM, M.A.; HORTON, W.E.; LOVEJOY, C.O.: Comparative analysis of mammalian proximal femoral development The mammalian proximal femur is highly complex in both anatomy and development. The greater trochanter and femoral head are each sites of secondary ossification even though both lie within a common epiphyseal cartilage. In some mammals (including humans), […]

HUBER, D. R. : Comparative Analysis of Methods for Determining Bite Force in the spiny dogfish Squalus Acanthias One of the critical factors in determining the trophic capabilities of fishes is their generated magnitude of bite force, which can be studied using the biomechanical concept of mechanical advantage and estimates of the maximum tetanic tension […]

ZEPNEWSKI, Eric*; NISHIKAWA, Kiisa: Collagen and Anuran tongues In previous studies, three non-exclusive mechanisms which frogs use to protract their tongues have been identified. These include mechanical pulling (short tongue frogs), inertial elongation (long tongue frogs), and hydrostatic elongation. In an evolutionary context, mechanical pulling is the most basal, while hydrostatic elongation is the most […]

ROSA, C.; BLAKE, J.E.; O’HARA, T.M.; MONNIER, V.: Collagen Aging in the Bowhead Whale (Balaena mysticetus) Age in marine mammals may be determined by various methods, ranging from simple photo re-identification to such methods as ear plug growth layer measurement, tooth growth layer group quantification, aspartic acid racemization in the teeth and eye lens nucleus, […]

HOBBS, S.L.; TSAI, P.-S.; NORRIS, D.O.: Cloning of a Partial Sequence of Kokanee Salmon Presenilin-1 Insoluble protein deposits of beta amyloid (A-beta) are one of two brain pathological markers used to diagnosis Alzheimer’s Disease (AD). Mutations in the human presenilin (PS) genes, primarily PS1, result in increased A-beta production and account for the majority of […]

HUANG, H.-D.*; RITTSCHOF, D.; JENG, M.-S.: Chemical and visual cues used in crionoid host selection by symbiotic snapping shrimp We hypothesized that obligate symbiotic snapping shrimp Synalpheus demani are able to locate and recognize crinoid hosts in a patched multi-species crinoid community. The present study tested S. demani’s responses to olfactory, visual and tactile cues […]

PODRABSKY, J.E.*; SOMERO, G.N.: Changes in Gene Expression Associated with Diurnal Temperature Cycling in the Annual Killifish Austrofundulus limnaeus Annual killifish thrive in small ephemeral ponds that experience wide fluctuations in temperature (22-39&degC) on a diurnal basis. The biochemical and molecular mechanisms that maintain cellular homeostasis during such temperature fluctuations are largely unknown. We are […]
