VONESH, J. R. *; DE LA CRUZ, O.: Modeling the effect of UV-B induced egg-stage mortality on the population dynamics of the Common Toad There has been increasing evidence of widespread population declines of amphibians from relatively undisturbed habitats. It has been suggested that ultraviolet radiation induced embryonic mortality has contributed to the decline of […]

KUFFNER, I.B.: Effects of ultraviolet radiation and water motion on the reef coral Porites compressa: A transplantation experiment Ultraviolet radiation (UVR, 280 – 400 nm) is an important ecological variable affecting coral reef organisms, but UVR effects may be influenced by other factors such as water motion. In this study, the effects of ambient UVR […]

COATES, M.M.*; THOMPSON, S.H.: Vision in a cubozoan jellyfish. Jellyfish of the class Cubozoa possess camera-type eyes similar to those of cephalopods and vertebrates; consisting of a lens, cornea, and retina. The retina is composed of three layers: a sensory layer, a pigmented layer, and a nuclear layer with extending nerve fibers. The cells of […]

Burnaford, J. L.: The physiology of positive interactions: effects of shade and season on endogenous levels of hsp70 in field populations of the black chiton Katharina tunicata Canopy-forming algae can be important to consumers by providing food and protection from predation or intense insolation. In the low rocky intertidal zone of the Pacific Northwest, the […]

Satterlie, R.A.*; Nolen, T.G.: The Small Number of Swim Pacemakers in Cubomedusae May Promote Biphasic Modulation of Swimming Activity Since the earliest behavioral investigations of scyphomedusan and cubomedusan swimming, swim contractions were found to be controlled by multiple pacemaker/sensory centers that were spread around the margin of the jellyfish. Coordination of swim pacemakers was presumed […]

EDWARDS, D.R.*; WOODIN, S.A.: Should worms of a feather stink together? The effects of prey density and aggregation on predator deterrence SHOULD WORMS OF A FEATHER STINK TOGETHER? THE EFFECTS OF PREY DENSITY AND AGGREGATION ON PREDATOR DETERRENCE. D.R. Edwards* and S.A. Woodin. University of South Carolina, Columbia. deirdre@sc.edu Halogenated hydrocarbons are widespread among hemichordates […]

TROWBRIDGE, C.D.* ; HIRANO, Y.J.: Marine specialist herbivores on high-diversity shores: Ecological notes of Japanese Ascoglossan (= Sacoglossan) Opisthobranchs. Most marine specialist herbivores belong to the molluscan order Ascoglossa, a group of suctorial sea slugs that show intriguing parallels with phytophagous insects. We investigated the ecology of ascoglossans in a region of high species richness: […]

Pedersen, S.P.: The impact of volcanic eruptions on the bat populations of Montserrat, BWI. Hurricanes and volcanic eruptions have had significant impacts upon the bat populations of Montserrat, underlined by the loss of 3 of its 10 species:Chiroderma, Sturnira, Noctilio. Seven surveys have documented population decreases following Hurricane Hugo in ’89 and the Soufriere Hills […]

Judd, T.M.*; Herbers, J.M.: The effects of moisture and time of year on the foraging preferences of the ant Pheidole ceres. Colonies of the ant Pheidole ceres are faced with an environment filled with variable food sources. The colony must be able to allocate its foragers to these food sources in order to maximize its […]

DINKELACKER, S.A.; WILSON, T. P.; HOWARD, J. H.: Spatial Ecology of Syntopic Bog (Clemmys muhlenbergii), Spotted (Clemmys guttata) and Snapping (Chelydra serpentina) Turtles in Maryland I examined differences in home ranges among syntopic species of turtles occurring within a 3-ha wetland in Carroll County, Maryland. I attached radio transmitters to the carapaces of bog (Clemmys […]
