Species whose geographic ranges span over various
regions with different seasonal regimes have different
reproductive schedules. For example, high-latitude species
might reproduce later close to the poleward side of their
range, and earlier near the equatorward side. On the other hand, regional patterns of larval
settlement are potentially less strictly dependent on a seasonal
schedule, because currents might transport larvae to and from sites
with individuals with different reproductive schedules. Settlement may
or may not be temporally correlated with the local reproductive
schedule.
We are investigating timing of larval release and
settlement in the circum-boreal barnacle Semibalanus balanoides.
Our sampling locations along Northeastern North America include
Connecticut, Rhode Island, Massachusetts, Maine, and Nova Scotia. Work
includes asses regional patterns of larval release together with
seasonal patterns of settlement.
