Variable Functional Responses Of A Marine Predator In Dissimilar Homogeneous Microhabitats, Rn Lipcius, Anson Hines Dec 1986

Variable Functional Responses Of A Marine Predator In Dissimilar Homogeneous Microhabitats, Rn Lipcius, Anson Hines

VIMS Articles

Adult soft-shelled clams (Mya arenaria) persist at low densities in Chesapeake Bay sandy habitats despite Intense predation by blue crabs (Callinectes sapidus). Clam persistence may be a consequence of variation in blue crab foraging rates as a function of clam density and sediment composition. In laboratory aquaria, we measured the functional responses (prey consumption per predator as a function of prey density) of large blue crabs to six densities of adult soft-shelled clams buried at natural depths in two sediment types (mud and sand). Functional responses in sand and mud were differentiated statistically by analyses of(1) residuals and residual sums …

The York River: A Brief Review Of Its Physical, Chemical And Biological Characteristics, Michael E. Bender Jan 1986

The York River: A Brief Review Of Its Physical, Chemical And Biological Characteristics, Michael E. Bender

Reports

The purpose of this paper is to provide an overview of the physical, chemical and biological characteristics of the York River, Virginia. The river is formed by the confluence of the Mattaponi and Pamunkey rivers at West Point, Virginia. It is tidal over its entire length and flows to the western shore of Chesapeake Bay.
