Emergence of Trematode Parasites from the Marine Snail Cerithidea californica

MALDONADO, E.M.*; FINGERUT, J.T.; ZIMMER, R.K.: Emergence of Trematode Parasites from the Marine Snail Cerithidea californica Light microscopy, video/visual analysis, and dissections of Cerithidea californica indicate that there is a specific route of emergence taken by the trematode cercaria Himasthla rhigedana, Euhaplorchis californiensis, and Renicola buchanani within their mollusc host. Video microscopy has shown that […]

Effects of substrate orientation on inclination of the orbital plane in Loris tardigradus

STEVENS, N.S.; HEESY, C.P.*: Effects of substrate orientation on inclination of the orbital plane in Loris tardigradus. The arboreal environment provides a complex three-dimensional network for balance and movement. One of the most obvious challenges is that branches differ in angular orientation. Primates have developed various techniques for negotiating inclines and declines. On oblique supports, […]

Effects of abiotic and biotic stresses on patterns of energy storage and use in two species of crustacean Gammarus pseudolimnaeus and Caecidotea intermedius

BARKAUSKAS, R.T.*; SPARKES, T.C.: Effects of abiotic and biotic stresses on patterns of energy storage and use in two species of crustacean: Gammarus pseudolimnaeus and Caecidotea intermedius. Effective energy budget management by an organism will influence its ability to tolerate both abiotic and biotic stress; however, except in birds little is known about the potential […]

Early Development of Interdigitation in Rat Cranial Sutures

JASLOW, C.R.*; LANIER, B.; HILL, E.: Early Development of Interdigitation in Rat Cranial Sutures The cranial sutures are highly variable, ranging from relatively straight edges to highly interdigitated interfaces between neighboring bones. Sutural interdigitation has been correlated with patterns of loading encountered by the sutures. However, it remains unclear whether sutural interdigitation is caused by […]

Does time of contact predict the metabolic cost of walking

JOHNSEN, D.A.J.*; GRIFFIN, T.M.; WICKLER, S.J.; COGGER, E.A.; HOYT, D.F.: Does time of contact predict the metabolic cost of walking? The metabolic rate during trotting and galloping is primarily determined by the rate of generating muscular force to support the body, which is inversely proportional to the time of contact (tc). Does this important generalization […]

Does c-start performance predict survival of prey encountering predators

BUNCE, J.A.; EBY, S.L.; O’STEEN, S.: Does c-start performance predict survival of prey encountering predators? The kinematics of swimming performance are increasingly well studied in fish, but the fitness value, if any, of most kinematic variables remains unknown. This study examines the relationship between classical c-start performance and the locomotor performance and survival of prey […]

Do pregnant lizards reabsorb or abort inviable eggs Morphological evidence from an Australian skink, Pseudemoia pagenstecheri

BLACKBURN, D.G.*; WEABER, K.K.; STEWART, J.R.; THOMPSON, M.B.: Do pregnant lizards reabsorb or abort inviable eggs? Morphological evidence from an Australian skink, Pseudemoia pagenstecheri. Among lizards and snakes, pregnant females commonly are believed to be able to reabsorb inviable embryos and infertile eggs from their oviducts. Such reabsorption would allow females to recycle nutrients, while […]

Diversity, functional morphology, and phylogeny of the Gynodiastylidae (Crustacea Cumacea)

GERKEN, S: Diversity, functional morphology, and phylogeny of the Gynodiastylidae (Crustacea: Cumacea). Cumaceans are small, benthic marine crustaceans, commonly assumed to be deposit feeders, which at times are locally abundant. In the course of a monographic treatment of the family Gynodiastylidae, the number of species and genera doubled, with the vast majority of new species […]
