“…Decapod assemblage patterns in seagrass beds and shallow marsh creeks from sub-tropical and temperate estuaries supported our observation [40,42,[81][82][83]. Diel difference in abundance might relate to diurnal changes in decapod behavior associated with variation in light intensity, turbidity, and tide forcing [84,85]. Rountree and Able [81] reported that young-of-the-year decapod were significantly more abundant at night due to their nocturnal movement into shallow marsh creeks.…”

Decapod assemblages in Zostera marina beds from two bays adjacent to unvegetated habitats were investigated to assess their influence on decapod assemblages. Thirty-eight decapod species belonging to four taxa were collected using a small beam trawl at four habitat types from two different locations off the coast of Namhae Island, South Korea. Dominant decapod taxon at all habitats was the caridean shrimps, with Eualus leptognathus, Heptacarpus pandaloides, Latreutes anoplonyx, La. Laminirostris, and Palaemon macrodactylus being the most abundant caridean species. Crabs were characterized with the highest biomass, but with moderate species richness and abundance. Penaeoid and sergestoid shrimps only accounted for <1% of the total decapod abundance. The number of species and their abundance of decapod assemblages varied greatly by habitat type, season, and diel patterns, but not diversity. Species number and abundance peaked in seagrass beds of southern exposed bays during the autumn and were lowest in unvegetated habitats during the summer months. Diel decapod catch rates were higher at night. Dense seagrass vegetation and nighttime supported higher decapod mean densities, but not species richness and diversity. Multivariate analyses revealed that habitat type and season significantly affected the structure of decapod assemblages, but diel patterns had a minor influence. Among decapod species, Pa. macrodactylus and Pugettia quadridens characterized the decapod assemblages in seagrass beds at the northern semi-closed bay, while Telmessus acutidens, Crangon affinis, Cr. hakodatei, Charybdis (Charybdis) japonica, and Portunus sanguinolentus were significantly associated with both vegetated and unvegetated habitats at the southern exposed bay, with the former two species more abundant during the colder season.

“…Depth preferences as well as diel and ontogenetic vertical migrations that have been previously documented seaward of the estuary for other species (Morgan et al 2009b(Morgan et al , 2012Morgan and Fisher 2010) were not detected in the estuary. Selective tidal stream transport was not evident either, even though reverse tidal vertical migrations have been reported for several species in other low-inflow estuaries (Queiroga et al 1997;Pereira et al 2000;Hsueh 2002;Breckenridge and Bollens 2011), including one of our study species (P. crassipes) in San Diego Bay .…”

“…Consequently, larvae may be less able to regulate depth and, hence, the rates and directions of transport. While reverse tidal vertical migration facilitates seaward transport of benthic crustacean larvae in several low-inflow estuaries, this behavior requires migration to the bottom boundary layer (very close to the seabed) and appears to be better defined in some estuaries and species than others (Queiroga et al 1997;Pereira et al 2000;Hsueh 2002;Breckenridge and Bollens 2011). Classic tidal vertical migrations facilitating larval retention have not been detected in low-inflow estuaries, and occupying bottom waters has been found only once (Pereira et al 2000).…”

“…Specifically, we determined the effectiveness of larval behavior by benthic crustaceans in regulating larval transport between a low-inflow estuary and coastal waters. We hypothesize that previously documented larval behaviors in adjacent coastal waters may not be evident in the estuary due to tidal vertical mixing and turbulence in shallow water (Breckenridge and Bollens 2011;Kunze et al 2013) or the lack of low salinity or pronounced salinity fluctuations to cue tidal vertical migrations (Miller and Morgan 2013a). Thus, we concurrently looked for vertical migrations in adjacent nearshore waters where salinity fluctuations are similar, but tidal flows and the strength of vertical mixing are weaker.…”

The effectiveness of larval behavior in regulating transport between well-mixed, low-inflow estuaries and coastal waters in seasonally arid climates is poorly known. We determined the flux of an assemblage of benthic crustacean larvae relative to physical conditions between a shallow estuary and coastal waters on the upwelling coast of northern California (38°18′N, 123°03′W) from 29 to 31 March 2006. We detected larval behaviors that regulate transport in adjacent coastal waters and other estuaries for only two taxa in the low-inflow estuary, but they were apparent for taxa outside the estuary. Vertical mixing in the shallow estuary may have overwhelmed larvae of some species, or salinity fluctuations may have been too slight to cue tidal vertical migrations. Nevertheless, all larval stages of species that complete development in nearshore coastal waters were present in the estuary, because they remained low in the water column reducing seaward advection or they were readily exchanged between the estuary and open coast by tidal flows. Weak tidal flows and gravitational circulation at the head of the estuary reduced seaward transport during development for species that completed development nearshore, whereas larval release during nocturnal ebb tides enhanced seaward transport for species that develop offshore. Thus, nonselective tidal processes dominated larval transport for most species back and forth between the low-inflow estuary and open coastal waters, whereas in adjacent open coastal waters, larval behavior in the presence of wind-induced shear was more important in regulating migrations between adult and larval habitats along this upwelling coast.
