Zooplankton abundance during summer in the Bay of La Paz (southwestern Gulf of California, Mexico)

ABSTRACT Marine zooplankton play key roles in the transfer of energy to higher trophic levels and the removal of CO2 from the atmosphere through the sedimentation of inorganic and organic carbon compounds included in their fecal pellets. Therefore, differences in the zooplankton groups driven by cli...
