Within tidal areas, early juveniles (J1–2) leave such nursery areas by undergoing secondary dispersal during nocturnal flood tides. The present study determined whether J1–2 blue crabs have a biological rhythm in vertical swimming activity that contributes to secondary dispersal. Endogenous rhythms in vertical swimming were determined for (1) J1–2 crabs collected from two estuaries with semi-diurnal tides, (2) J1 crabs that metamorphosed from the megalopal stage in the laboratory the day after collection, and (3) premolt megalopae that metamorphosed to J1 crabs under constant conditions during the experiment. In all cases, a circadian rhythm was present in which crabs swam vertically during the time of night in the field. The time of peak vertical swimming did not correspond to the time of flood tide at the collection sites, but did consistently occur at night, with a mean around midnight. While responses to environmental factors probably control the onset and end of vertical swimming by early juvenile blue crabs during flood tides in tidal areas, a circadian rhythm underlies secondary dispersal at night.}, number={1}, journal={JOURNAL OF EXPERIMENTAL MARINE BIOLOGY AND ECOLOGY}, author={Forward, RB and Reyns, NB and Diaz, H and Cohen, JH and Eggleston, DB}, year={2005}, month={Mar}, pages={91–100} }

Crabs in the first–fifth instar stages (J1–5) then emigrate from these areas by walking on the bottom or pelagic dispersal throughout estuaries. The present study was designed to characterize the timing of this migration pattern relative to the light–dark and tidal cycles. Field sampling in Pamlico Sound, NC, USA indicated that J4–5 juveniles were most abundant in the water column during the night. J4–5 juveniles were collected from Pamlico Sound in an area near Oregon Inlet that has semi-diurnal tides, a Mid-Sound area where tides are weak, and on the West side where regular tides do not occur. Crabs from all three sites had a circadian rhythm in which they swam up in the water column during the time of darkness in the field. Peak swimming consistently occurred at about 0300 h, but was not related to the timing of the tidal cycle. Similar results were obtained for juvenile crabs from an adjacent estuary having semi-diurnal tides. Dispersal at night reduces predation by visual predators, and allows early juvenile blue crabs to disperse planktonically from initial settlement sites.}, number={1}, journal={JOURNAL OF EXPERIMENTAL MARINE BIOLOGY AND ECOLOGY}, author={Forward, RB and Reyns, NB and Diaz, H and Cohen, JH and Eggleston, DB}, year={2004}, month={Feb}, pages={63–76} }

We examined the physical environmental (wind, diel cycle, tidal phase) and biological (ontogenetic, density-dependent) factors that contribute to the secondary dispersal of a benthic marine invertebrate, the blue crab (Callinectes sapidus) in Pamlico Sound, NC, USA. Field studies conducted in relatively large (0.05 km2) seagrass beds determined that secondary dispersal is primarily undertaken by the earliest juvenile blue crab instar stages (J1 crabs). These crabs emigrated pelagically from seagrass settlement habitats using nighttime flood tides during average wind conditions (speed approximately 5 m s-1). Moreover, the secondary dispersal of J1 crabs was density-dependent and regulated by intra-cohort (J1) crab density in seagrass. Our results suggest that dispersal occurs rapidly following settlement, and promotes blue crab metapopulation persistence by redistributing juveniles from high-density settlement habitats to areas characterized by low postlarval supply. Collectively, these data indicate that blue crab secondary dispersal is an active process under behavioral control and can alter initial distribution patterns established during settlement. This study highlights the necessity of considering secondary dispersal in ecological studies to improve our understanding of population dynamics of benthic organisms.}, number={2}, journal={OECOLOGIA}, author={Reyns, NB and Eggleston, DB}, year={2004}, month={Jul}, pages={280–288} }
