BISHOP, Renee E.; GEIGER, Stephen P.; MC CULLON, Joseph Jr.: Phronima Energetics: Life of a planktonic stowaway The hyperiid amphipods of the genus Phronima have adapted to the pelagia by hollowing transparent barrels from salps. The amphipods reside in the salp barrels and pilot them through the water. This unique behavioral adaptation may provide advantages […]

HUNT VON HERBING, I: Growth in the fast lane: metabolic scaling and activity in developing fishes. Embryonic and larval growth rates are high(50% d,-1)in some species,while juveniles have growth rates of 1-6%d-1.Given finite energy supplies,how can embryos and larvae simultaneously maintain high growth rates,swim and perform other metabolic processes? High growth rates are costly as […]

MORAN, A.L.*; MANAHAN, D.T.: Energy metabolism during larval development of two abalone species, Haliotis fulgens and H. sorenseni Lecithotrophic larvae of marine organisms develop to metamorphosis without feeding on plankton. An understanding of the biochemical and physiological energetics of lecithotrophic development is useful for interpreting patterns of larval development and dispersal. This study investigates the […]

GINSBURG, D.W.; MANAHAN, D.T.: Biochemical bases of metabolic intensity during sea urchin development Early stages of development require increased oxygen consumption to support energetically demanding processes, such as rates of protein synthesis and maintenance of ion gradients in the increasing number of cells. Little is known about the relationship among these physiological processes and their […]

BACHMAN, G.C.; Univ. of Nebraska, Lincoln: The cost of breeding : Energy availability and the recovery of immune function in recently emerged hibernators. Injury and subsequent infection are a potential cost of breeding in male mammals. Even where males are not wounded, the immunosuppressive effect of endocrine changes during breeding can increase a male’s susceptibility […]

LECLAIR, E. E.; NOMELLINI, V.; BAHENA, M.; BINGLE, C.D.; DePaul University; University of Sheffield: Innate Immunity in the Oral Cavity? A Mouse Tongue Tale Epithelial surfaces are patrolled by molecules that recognize bacterial byproducts to enhance host defense. We describe the cloning and expression of a mouse gene, which we call TPL, whose mRNA appears […]

OWEN-ASHLEY, N. T.; HASSELQUIST, D.; WINGFIELD, J. C.; Univ. of Washington, Seattle; Lund Univ., Lund, Sweden; Univ. of Washington, Seattle: Indirect mechanisms of testosterone-induced immunosuppression in songbirds: a new paradigm We investigated the effect of different androgens on immune function in song sparrows (Melospiza melodia). The immunocompetence handicap hypothesis predicts a tradeoff between suppressive effects […]
