Environmental perturbation baseline δ15N values zooplankton trophic flexibility southern California Current Ecosystem
2014/4/2
Nitrogen isotopic compositions of zooplankton in the California Current Ecosystem (CCE) are known to vary over inter-annual scales of climate variability, but the extent to which those changes are dri...
