Gulf and Caribbean Research
The opossum pipefish, Microphis brachyurus lineatus, is a migratory syngnathid with a salmon-like life history (Frias-Torres 2002). Adults breed in freshwater and oligohaline habitats associated with emergent vegetation, mostly Panicum sp. and Polygonum sp.; breeding occurs during the wet season (May to November) (Gilmore and Hastings 1983). In southern Mexico, opossum pipefish associate with Ruppia maritima, and reproduction is year-round (Miranda-Marure et al. 2004). Pelagic juveniles are found in the Atlantic Ocean and are associated with Sargassum sp. (Böhlke and Chaplin 1968). Juveniles eventually recruit into oligohaline habitats. The species range is from Sao Paulo, Brazil, to New …

Benthic-Pelagic Coupling In Northern Gulf Of Mexico Estuaries: Do Benthos Feed Directly On Phytoplankton?, Gary R. Gaston, Carol M. Cleveland, Steven S. Brown, Chet F. Rakocinski
Gulf and Caribbean Research
Few of the dominant benthic taxa of the northern Gulf of Mexico feed directly on phytoplankton. Rather, most of them feed on near-bottom seston and detritus. This is in contrast to models for Chesapeake Bay and San Francisco Bay. We found that detritivores represented over 80% of the macrobenthic organisms and over 90% of the biomass in Gulf of Mexico estuaries. The paucity of benthos that consumed phytoplankton led us to hypothesize that macrobenthos in Gulf of Mexico estuaries had less effect on plankton communities than was documented in U.S. east coast and west coast estuaries, where benthic communities consumed …
