Policy Implications Of Managing Biodiversity And Natural Resources Across International Boundaries, Dillon Brown

Dissertations

Fisheries Management under the best of scenarios is a complex action. It requires thoughtful consideration of resources that tend to be out of sight, widely distributed, highly variable both spatially and temporally, and present dramatic variation in life history and ecology. No one management approach has been developed which can effectively incorporate all these variables. Add to this the issue of transnational boundary movements of these resources, and one discovers that this complex issue needs to be addressed by multiple entities, agencies, and nations to have any chance of success.

This research set out to discover ways in which fisheries …

New Sandhoppers (Crustacea: Amphipoda) From The Gulf Coast Of The United States, E.L. Bousfield

Gulf and Caribbean Research

Three species of sand-burrowing semi-terrestrial amphipod crustaceans are newly described from sandy beaches of the North American coast of the Gulf of Mexico. They (and two related species from the open Atlantic coast of North America) are removed from the genus Talorchestia Dana 1853, and placed in a new genus, Americorchestia. Americorchestia salomani, new species, and A. heardi, new species, occur from northwestern Florida to the Mississippi Delta. They are morphological counterparts of the well-known sandhoppers from the open Atlantic coast, A. megalophthalma (Bate) and A. longicornis (Say) respectively. Americorchestia barbarae, new species, related to A. …

A Range Extension For Manayunkia Aestuarina (Bourne, 1883) (Polychaeta: Sabellidae) To The Gulf Coast Of The United States With A Review Of Previous Habitat Information, T. Dale Bishop

Gulf and Caribbean Research

The sabellid polychaete Manayunkia aestuarina (Bourne, 1883) is reported for the first time from the Gulf coast of the United States and from a Juncus roemerianus marsh. Individuals were collected from a brackish J. roemerianus marsh in St. Louis Bay, Mississippi, (30^o22'N, 89^o15'W) during the period of June 1979 to May 1980. Adults with eggs were first noted in early January and increased in number through May. Brooded young were observed from late January through May. Habitat comparisons are made between this and other North American and European populations. The present population is associated with lower …

Observations On The Food And Food Habits Of Clapper Rails (Rallus Longirostris Boddaert) From Tidal Marshes Along The East And Gulf Coasts Of The United States, Richard W. Heard

Gulf and Caribbean Research

The feeding habits of five nominal subspecies of clapper rails (Rallus longirostris Boddaert) collected in tidal marshes along the Gulf and Atlantic coasts of the United States are compared. Data on the food from the stomachs of 183 rails were analyzed and the earlier literature critically reviewed. During the warmer months (May through early fall), crabs, predominantly Uca spp., comprised the major part of the food items found. Limited data on a few rails collected during late fall and winter, when Uca spp. are not usually available, indicate that snails then become a major part of the clapper rail’s …
