Local and regional patterns of fish assemblages in coastal lagoons surrounded by mangroves, Gulf of Tehuantepec in the south Pacific of Mexico

ABSTRACT We analyzed the local variation of fish assemblages in four coastal lagoon systems surrounded by mangroves, draining into the Gulf of Tehuantepec (Pacific versant of Mexico), and determined the spatial patterns of alpha, beta, and gamma diversity. Fish were sampled between 2004 and 2016 at...
