Ecology Of The Benthos Of The Lower Chesapeake Bay (Maryland), Linda C. Schaffner Jan 1987

Ecology Of The Benthos Of The Lower Chesapeake Bay (Maryland), Linda C. Schaffner

Dissertations, Theses, and Masters Projects

The spatially complex lower Chesapeake Bay estuary is characterized by a variety of bottom types and hydrodynamic regimes. to account for this physically-induced variability a benthic habitat delineation scheme was developed based on existing knowledge of physical and geological characteristics. Within the context of this scheme a series of studies were conducted to identify biotic response to and interactions with the physical, chemical and geological gradients that characterize the lower Chesapeake Bay. These studies characterized organism distribution and abundance patterns within the lower bay and identified processes controlling those patterns. The biological community of the polyhaline basin habitat, an area …


Studies Of Pipefish Foraging In Simulated Seagrass Habitats, Clifford H. Ryer Jan 1987

Studies Of Pipefish Foraging In Simulated Seagrass Habitats, Clifford H. Ryer

Dissertations, Theses, and Masters Projects

Laboratory experiments determined the effects of two levels of habitat complexity upon pipefish (Syngnathus fuscus) foraging for amphipods. Habitats were composed of equal densities of either narrow (low complexity) or wide (high complexity) leafed artificial seagrass. The response to habitat, as measured by rate of encounter with amphipods, probability of attack after encounter, probability of success after attack, and overall rate of amphipod consumption, was determined for combinations of two fish size classes and three amphipod size classes. Small fish did not experience visually inhibitive effects in either habitat, while large fish had their visual fields impinged upon in the …


Aspects Of The Ecology Of Estuarine Light With Special Reference To Seagrasses Of The Chesapeake Bay: Measurements And Models, Robin Francis Van Tine Jan 1987

Aspects Of The Ecology Of Estuarine Light With Special Reference To Seagrasses Of The Chesapeake Bay: Measurements And Models, Robin Francis Van Tine

Dissertations, Theses, and Masters Projects

The temporal spectral light environment of shallow areas of the lower Chesapeake Bay was characterized by cosine collection of downwelling diffuse irradiance at 12 wavelengths between 400 and 700 nm. An extensive monthly and site comparison of spectral attenuation coefficients is presented and compared with previous measurements of the light quality environment of the Chesapeake Bay and other estuaries and marine waters. Spectral irradiance and attenuation of light in a mangrove creek and Thalassia testudinum bed of Laguna de Terminos, Campeche, Mexico and their relationships to wind-driven suspension of particulate matter, and dissolved substances from the mangrove swamp is also …
