Salinity and sedimentation rate influences on the community structure of polychaetes associated with two sympatric congeneric oyster species.

This study focused on spatial-temporal variations in the composition and structure of polychaete communities associated with two coexisting oyster species in a southern Gulf of Mexico coastal lagoon, showed that Crassostrea rhizophorae hosted 23 polychaete species and C. virginica only four. The observed variability was mainly explained by differences in salinity and sedimentation rate, two factors that also influenced the host species distribution.

Assessment of aquatic food web and trophic niche as a measurement of recovery function in restored mangroves in the Southern Gulf of Mexico.

Mangroves are coastal wetlands with high biodiversity and productivity, with great interaction with coastal environments. In the face of worldwide mangrove loss, restoration projects attempt to recover ecosystem composition and functioning over time. Our objective was to examine and compare the food webs in mangrove areas with different restoration times and in a reference mangrove in Términos Lagoon, Mexico.

Absence of hypoxia events in the adjacent coastal waters of Grijalva-Usumacinta river, Southern Gulf of Mexico.

Globally, oxygen concentration in many coastal areas is depleting. River nutrient discharges may produce hypoxia events. The Southern Gulf of Mexico receives the discharges of the Grijalva-Usumacinta River System, the second largest in the Gulf of Mexico.
