Variation in the release and recruitment of larvae of estuarine invertebrates affects the distribution and abundance of adults, as well as trophic interactions in both the plankton and the benthos. Larval release and supply are often timed to environmental cycles such as the diel and tidal cycles. Here, we determined using plankton tows whether the abundance of larvae spanning salt marsh and mangrove habitats across the intertidal landscape varied with diel and tidal cycles. Using three… 
Biotic vs. abiotic forcing on plankton assemblages varies with season and size class in a large temperate estuary
Large river estuaries experience multiple anthropogenic stressors. Understanding plankton community dynamics in these estuaries provides insights into the patterns of natural variability and
Tidal, diel and lunar patterns in intertidal and subtidal mangrove creek fish assemblages from southwest Thailand
Estuarine mangrove fish studies of the Andaman Sea region may suffer significant bias when the importance of tidal-lunar and diel cycle interactions are not considered because the role of Ambassidae will be strongly underestimated.
Effects of Tropical Saltmarsh Patches on the Structure of Benthic Macrofaunal Assemblages
Habitat complexity can affect assemblage abundance, richness and composition by providing resources and mediating ecological interactions for an array of organisms in many ecosystems. Temperate
Impacts of water quality on Acropora coral settlement: The relative importance of substrate quality and light
This work applies programmable multispectral lights to create realistic light spectra to find little evidence that light intensity or changes in the spectral profile play a substantial role in larval settlement under most environmentally realistic settings but can under more extreme or artificial settings.
Environmental Characteristics on Larval Release of Rockworm Polychaete Marphysa sanguinea
This study investigates the relationship between environmental factors, such as semilunar rhythm and atmospheric pressure, and the release of Marphysa sanguinea larvae. During artificial seed
Equivalence of trophic structure between a tropical and temperate mangrove ecosystem in the Indo-Pacific
In this study we compared ecosystem trophic structure between a tropical mangrove forest at Matang, Malaysia, and a temperate mangrove forest near mangrove poleward limits at Towra Point in
Mass spawning of crabs: ecological implications in subtropical Australia
The link between sediment organic matter, crab and zooplanktivore isotopic composition remained tightly coupled in spite of variation in anthropogenic N between estuaries and the isotopic signature of mangroves.


Diurnal and lunar patterns of larval recruitment of Brachyura into a mangrove estuary system in Ranong Province, Thailand
It is concluded that megalopae recruit in a similar manner to what has been found in other regions of the world, except that the abundance of ocypodids and Metaplax is not influenced by the diel cycle.
A field study to describe diel, tidal and semilunar rhythms of larval release in an assemblage of tropical rocky shore crabs
The field methods applied to describe the larval release rhythms of an assemblage of tropical rocky shore crabs suggest that breeding groups release their larvae in alternate syzygy periods, responding to a lunar cycle instead of the semilunar pattern observed for the whole population.
Dispersal and recruitment of fiddler crab larvae in the Delaware River estuary
In spite of a semi-terrestnal adult habitat, fiddler crabs of the Middle Atlantic Bight show no adaptahon for retaining larvae in hdal marsh creeks Abundant data show that newly hatched zoeae are
Planktivory as a selective force for reproductive synchrony and larval migration
Diurnally foraging planktivorous fishes, crabs, and fishes collected in Flax Pond salt marsh suggest that reproductive and larval behaviors largely overcame mortality during the planktonic phase of the life cycle and coupled production to recruitment, regardless of whether or not recruits primarily originated from local populations.
Nearshore larval retention in a region of strong upwelling and recruitment limitation.
It is shown that 45 species of nearshore crustaceans were not transported far offshore in a recruitment-limited region characterized by strong upwelling, and larvae are more likely to recruit closer to natal populations than is widely believed.
Paradigm lost? Cross-shelf distributions of intertidal invertebrate larvae are unaffected by upwelling or downwelling
Upwelling and downwelling had no effect on the cross-shelf distribution of the larvae of intertidal invertebrates and the hypothesis that upwelling carries larvae offshore and down welling carries them back onshore was not supported.
Trophic importance of a temperate intertidal wetland to resident and itinerant taxa: evidence from multiple stable isotope analyses
The present study highlights the significance of mangrove and saltmarsh wetlands as a feeding habitat for resident grazers and itinerant nekton and investigates the contribution of wetland primary producers and grazing herbivores to these habitats.
Larval supply, settlement and survival of barnacles in a temperate mangrove forest
Cyprids of the barnacles Elminius covertus and Hexaminius popeiana were sampled in the water column at differing distances from the seaward edge within a mangrove forest and at different tidal
Supply-side ecology works both ways: The link between benthic adults, fecundity, and larval recruits
It is predicted that large-scale patterns of recruitment could be driven by changes in the abundance of adults and/or their fecundity, i.e., that corals exhibit a stock-recruitment relationship, and implies that small, sublethal changes in fecundities of corals could result in major reductions in recruitment.
