Seasonal variability of near-surface zooplankton community structure in the southern Gulf of Mexico

ABSTRACT The zooplankton taxonomic group composition was analyzed in a known spawning area for snooks of the family Centropomidae during March 2011-February 2012 near the González River’s mouth, a tributary of the Grijalva-Usumacinta River system, discharging into the southern Gulf of Mexi...
