Biocenosis of benthic community in Guerrero Negro Lagoon, Baja California Sur, Mexico: spatio-temporal characterization
In order to know and characterize the benthic marine community at Guerrero Negro Lagoon, Baja California Sur, Mexico, a monitoring during six months were conducted, sampling 10 stations every month from July to December of 2012. Collected samples were taken with 0,50 m² quadrants by scuba between 5...
