Regional patterns in reproduction and settlement

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.
