Earlier spring?

Echinopluteus Larva  Phenology _echino  Crab Larvae2 

In recent years the CPR survey has found that some species of meroplankton (larval marine organisms) are emerging earlier in the spring.  Decapods (crabs and shrimps) and echinoderms (starfish and brittle stars) have been found in our plankton samples 4 - 5weeks earlier than the long term mean.  This trend has been highly correlated with an increase in sea surface temperature (SST).
