HUANG, H.-D.*; RITTSCHOF, D.; JENG, M.-S.: Are Anemonefish Lures? An experimental analysis of chemically and visually mediated anemonefish and grouper behavior Anemone fish display specific swimming behaviors when chemically stimulated by their anemone hosts (Murata et al., 1986). The present study tests if these behaviors function to lure anemone fish predators into becoming anemone prey. […]

SCHAEFER, J. T.*; SCHULTZ, E. T.: Scaling allometry of energy allocation to growth and storage in temperate populations of an annual fish, Pimephales promelas The allocation patterns of acquired energy to growth or storage are subject to environmental factors and may be modified by evolution. Selective pressures on the allocation strategies of annual temperate fish […]

PETERSEN, J.; ADOLPH, S.C.*: Lizards in a Fluctuating Environment: a Stochastic Population Model for the Desert Night Lizard Xantusia vigilis We constructed and analyzed a stochastic population model for the desert night lizard (Xantusia vigilis) in the western Mojave Desert of California. The model is based on demographic data of Zweifel and Lowe (1966), who […]

TILLACK, M.A.*; BRAITHWAITE, L.F.: Feeding Methods of Balanus eburneus and Balanus amphitrite in the Indian River Lagoon, Florida Filter feeding of barnacles can be active or passive. Active filter feeding involves stroking the water with the filter structures, with the organisms expending significant energy. Passive filter feeding involves holding the cirri up into the water […]

TROWBRIDGE, C.D.: Emerging associations: sacoglossan opisthobranchs associated with introduced macroalgae On temperate European shores, the native stenophagous marine herbivore Placida dendritica associates with the green macroalga Codium fragile introduced from north Pacific shores. On Scottish coasts, adult P. dendritica collected from introduced hosts prefer to associate with and consume the introduced hosts than the native […]

SWIMMER, Y; BRILL, R; MAILLOUX, L; MOYES, C: Cardiac Biochemistry in Three Species of Tuna with Widely Divergent Temperature Tolerances Tracking of pelagic tunas reveals strikingly different depth and temperature distributions among three congeners–yellowfin (Thunnus albacares), skipjack (Katsuwonus pelamis), and bigeye (T. obesus). The former spend 60-80% in relatively warm water (~20 to 28oC) and […]

TUBERTY, S.R.: Effects of the insect juvenile hormone agonist, methoprene, on female growth and reproduction in the Gulf sand fiddler crab, Uca panacea. Adult Uca panacea were distributed randomly (250 females, 100 males per pond) into six estuarine ponds in order to determine the effects of field applications of methoprene (Altosid� XR briquets) on female […]

DOHM, M.R.*; MAUTZ, W.J.: Effects of ozone on marine toad thermoregulatory behavior and immune function Ozone (O3) is a common air pollutant in many urban settings, and in the adjacent wildlife habitats, O3 levels frequently exceed the U.S. federal standard of 0.12 ppm. Ozone is a strong pulmonary irritant and causes a suite of thermoregulatory, […]

SCHOENFUSS, H.L.*; MARTINOVIC, D.; SORENSEN, P.W.: Effects of Water-Borne 17b-Estradiol on Reproductive Fitness in Two Species of Fish To assess the effects of endocrine disrupters on the reproductive health of male fish, we exposed male goldfish (a substrate spawner) and fathead minnows (a nest guarding species) to waterborne estradiol at a concentration found in some […]

LOVE, O.P.; SHUTT, L.; BIRD, D.M.: Dietary PCB-induced impairment of the adrenocortical response in captive American kestrels We examined the effects of dietary exposure to PCBs on the adrenocortical response in American kestrels (Falco sparverius). Nine captive male American kestrels previously exposed to elevated levels of a mixture of PCB congeners (1248:1254:1260; 1:1:1) in their […]
