“…Ammonium concentrations in water samples taken above the test sediments both prior and subsequent to addition of new juveniles of both Arenicola and Mercenaria were relatively low (mean < 3.0 µM for "Medium" and < 8.4 µM for "High") and within the range of water column concentrations for the North Inlet (Marinelli and Woodin, 2004). This suggests the disturbance of porewater associated with the addition of new juveniles was minimal.…”

Recent studies have shown that local variation in sediment geochemistry can have significant effects on settlement rates of benthic invertebrates. For example, elevated porewater ammonium concentrations in soft-sediment benthic systems may result in decreased recruitment rates of settling larvae. Recruitment responses of the benthic polychaete Arenicola cristata and the bivalve Mercenaria mercenaria to varying ammonium concentrations were measured in realistic flow environments.Experiments made novel use of ammonium-spiked polyacrylamide gels placed beneath field-collected sediment, which produced predictable porewater ammonium concentrations. Post-larval arenicolids and Mercenaria were allowed to settle in an annular flume containing sediment treatments with varying ammonium concentrations. Porewater ammonium data indicated successful manipulation of geochemical properties without contamination of overlying water. In Mercenaria trials, recruit retention was low. For Arenicola trials, significant retention differences were observed as a function of ammonium concentration, and indicate that ammonium plays a significant role in determining recruitment patterns and hence juvenile abundance.

“…In soft-sediment communities, local recruitment may be affected by grain size and sediment chemistry, which in turn can be influenced by resident organisms (e.g. Hockin 1982, Snelgrove & Butman 1994, Wu & Shin 1997, Marinelli & Woodin 2004, Beukema & Dekker 2005. Polluted sediments may affect settlement (Lenihan et al 2003, Stark et al 2004, Lu & Wu 2006, although it is difficult to distinguish this effect from early mortality.…”

Variation in recruitment does not drive the cline in diversity along an estuarine gradient

Spatial pattern and intensity of recruitment have substantial effects on adult community structure in some but not all marine systems. Such 'supply-side' effects have been relatively poorly studied in soft-sediment habitats because of the difficulty of sampling very small infaunal recruits. I investigated whether spatial patterns of infaunal recruitment along an estuarine gradient could account for the observed cline in adult diversity. On 9 occasions spread over 13 mo, cores of sterile sediment from 2 different sources were embedded in beaches along the estuarine axis of Puget Sound, Washington, and sampled 6 wk later for new recruits. Identities and abundances of recruits (mostly polychaetes and bivalves) varied among seasons, but differed little between sediments from different sources. Contrary to expectations, neither recruit richness nor abundance was lower at the southern (more estuarine) end of the gradient, where adult taxonomic diversity is low. For a number of taxa and time periods, recruitment was actually stronger at the southern beaches. Multivariate differences between assemblages of recruits and adults were much greater at the southern sites, indicating that post-recruitment processes at these sites modify diversity and abundance patterns initially established by recruitment. These processes could include predation on juveniles, adult -juvenile competition, or physiologically stressful abiotic conditions.

Nevertheless, sites with consistently high recruitment do not necessarily have large adult populations, illustrating the intervention of post-recruitment mortality (Olafsson et al. 1994). Predation on and bioturbation of larvae and juveniles can reduce abundance and impose new patterns on adult assemblages (e.g. Beukema & Dekker 2005, Pillay et al. 2007); however, experiments on these processes are often confounded by cage artifacts (Peterson 1979). Food subsidies for recruits are thought to affect growth more than survival (Peterson 1982, Olafsson et al. 1994, although food resource levels in surface sediments may affect both larval settlement behavior and subsequent survivorship. Abiotic factors such as sediment movement or physiologically stressful conditions can also affect survival (e.g. Labrune et al. 2007).Few field studies in soft sediments have quantified settlement per se (propagules reaching the bottom at a site) because of the difficulty of sampling very small infauna (Smith & Brumsickle 1989, Hunt et al. 2003, Reiss & Kroncke 2005, so patterns of recruitme...

The aim of the present study was to understand how larvae and juveniles of the opportunistic polychaete Capitella sp. I respond to natural sediments with varying biochemical properties. Muddy sediments of a similar particle size spectrum were collected from 5 sites in Hong Kong along a pollution gradient of domestic sewage on 4 sampling occasions in both wet and dry seasons. The sediments were used to study the influence of organic matter quantity and composition (i.e. total organic carbon [TOC], total nitrogen [TN], chlorophyll a, biopolymeric carbon and enzymatically hydrolysable amino acid contents) on larval metamorphosis (i.e. habitat selection) and juvenile performance (i.e. growth and survivorship). Organic matter quantity and composition varied with sampling date and site. Still water multiple-choice experiments showed that larval choice at settlement varied with spatial and temporal variations in sediment biochemical properties. A series of experiments in the study also showed that both the quantity and the composition of organic matter affect the attractiveness of substrates to larvae and appear to play a key role in determining larval behavior at the time of settlement. Further laboratory experiments showed that larvae did not choose to settle on sediments from sites where juvenile growth was poor and mortality was higher. Our field data indicated that both larval metamorphosis and juvenile performance patterns observed in this laboratory study partially corroborate data on the abundance of adult Capitella spp. in the field. Overall, this study suggests that the field distribution of Capitella sp. I, and consequently species composition in a community, could be determined by the habitat selection by larvae and early juvenile performance. KEY WORDS: Capitella sp.
