“…A transport mechanism similar to that described here may occur with ingress of Atlantic blue crabs to Delaware Bay (Little and Epifanio 199 1) and Chesapeake Bay (Goodrich et al 1989). In these cases, influx of megalopae corresponds with periods of southward winds and consequent positive anomalies in sea level (Little and Epifanio 199 1).…”

The temporal pattern of settlement of King George whiting (Sillaginodes punctata) in Port Phillip Bay, Australia, was compared with the temporal ingress of passive particles to the bay from adjacent coastal waters, predicted by a numerical hydrodynamic and dispersal model. The settlement data and the numerical model showed significantly correlated pulsing on an approximate 10–14‐d period. Pulsing was not obviously associated with individual oceanographic or climatic variables but was most likely caused by a combination of factors related to the passage of pressure systems and associated rotating winds that occur on a 7–14‐d cycle in this region. Such factors may include low‐frequency oscillations related to barometric pressure, reversals in longshore currents, and coastal trapped waves. Additionally, these processes would interact with the spring‐neap tidal cycle. The strong tidal currents in the region of settlement may overwhelm the behavioral responses of larvae and cause them to act as passive particles. High interannual variability in recruitment of S. punctata may relate to variation in the frequency and timing of hydrodynamic events that allow transport of larvae to juvenile habitats.

“…Larval advection of the polychaete Pectinaria korenii from the eastern Baie de Seine to Baie des Veys in the English Channel was demonstrated only during extreme wind conditions, otherwise larval dispersal was limited to within the natal habitats (Jolly et al 2003 and references therein). Mass settlement of blue crab megalopae in Chesapeake Bay has also been observed due to a bay-inflow event caused by a hurricane (Goodrich et al 1989). More research on the causes of recruitment variability in large species, including S. kagoshimensis, is necessary for efficient restoration in the deteriorated benthic community of Ariake Bay.…”

Small species often dominate benthic communities in hypoxia-stressed sites, but the organizing process has rarely been investigated. Community assembly was investigated in northwestern Ariake Bay, which is exposed to hypoxia during summer. Sampling was performed 11 times between May 2010 and May 2012. The timing and duration of hypoxia differed between 2010 and 2011, which caused a different pattern of seasonal change in the community structure between the 2 years. The community was mainly composed of small species such as Theora fragilis, Veremolpa micra, and Sternaspis scutata at all times. The exception was the large arcid bivalve Scapharca kagoshimensis. This bivalve newly settled after hypoxia in 2010 and became a dominant species of the subsequent community, whereas its density decreased greatly after hypoxia in 2011. Interestingly, new settlement of arc shells did not occur in 2011 when hypoxia was relatively moderate compared with that in 2010. These results suggest that small species dominance at a hypoxia-stressed site cannot be attributable only to repeated hypoxic devastation and quick recovery of short-lived small species but also to the variability in natural recruitment of long-lived large species. Large species cannot easily recover if low recruitment years continue, even if hypoxic conditions are moderate. Therefore, the need for more attention to recruitment variability of large species is emphasized in striving to understand community assembly and efficiently restore coastal soft bottom communities that have deteriorated due to hypoxia.

“…Goodrich et al, 1989;van Montfrans et al, 1990;Boylan & Wenner, 1993;Wrona et al, 1995;Hasek & Rabalais, 2001) suggest that this type of sampling reflect natural settlement rates and respective temporal intensity patterns. Strictly on a temporal basis it may be true, but when spatial patterns are concerned, the present results make this statement very doubtful.…”

The Use of Artificial Benthic Collectors for Assessment of Spatial Patterns of Settlement of Megalopae of Carcinus maenas (L.) (Brachyura: Portunidae) in the Lower Mira Estuary, Portugal

Artificial benthic collectors have been widely used for the assessment of settlement rates of decapod crustaceans. However, to date no consistent works have addressed spatial patterns of settlement in different estuarine habitats, and no specific studies targeted the interaction of artificial surfaces with the surrounding natural substrate. It may be expected that the artificial surface may produce a different thigmotactic response when compared to the natural substrate, which may limit the use of this technique for assessment of natural settlement rates. In this study the settlement rates of megalopae of the estuarine crab Carcinus maenas were addressed, specifically deploying artificial benthic collectors in different habitats both intertidal and subtidal in the lower Mira estuary. A number of experiments were performed concerning stratification and temporal fluctuations of settlement. Further, the interaction of collector surface with the surrounding substrate was investigated, by comparing settlement rates in natural and artificial substrates in different habitats. Results have shown significant differences in settlement between different estuarine habitats, both in spatially replicated experiments and in a high-resolution temporal experiment. However, comparison between settlement rates in artificial and natural substrates has shown that there is a strong interference between collectors and surrounding substrate, limiting interpretation of results concerning settlement rates in artificial substrate alone.
