For historical reasons, knowledge about seasonality in the dynamics of mari
ne benthic suspension feeders from temperate areas comes mainly from studie
s of cold temperate seas. Recent surveys of Mediterranean taxa show differe
nt patterns from those observed in cold temperate seas, which are character
ized by winter dormancy. In the Mediterranean, summer dormancy predominates
among taxa and appears to be related to energetic constraints. Temperature
and food availability are crucial to the dynamics of benthic suspension fe
eders. However, because these factors tend to be positively correlated in c
old temperate seas, it is difficult to distinguish between their effects. S
uch correlation does not occur in Mediterranean ecosystems. The contrast be
tween recent studies in the Mediterranean and in other areas can help to di
sentangle confounded environmental controls.
