TL;DR: For these sympatric shallow-water agariciid corals, larval metamorphosis and recruitment are not wholly stochastic lottery-like processes, but instead appear to be determined, in part, by larval recognition of and responses to, environmental and biochemical factors that can be experimentally resolved and identified.

TL;DR: Gut clearance rate constant (K) of T. longicornis was positively related to temperature (T) and the relationship was best described by the equation K = 0.0119 + 0.001904T, and it is suggested that K may be estimated by knowledge of ambient temperature if food conditions are not limiting.

TL;DR: It is suggested that some coral reef fish larvae use dissolved chemical cues to choose or to avoid settlement sites, as well as a number of other species, due either to selective settlement or to differential persistence.

TL;DR: Litter bag experiments were used to follow changes in mass and chemical constituents during decomposition of leaves from three mangrove species, Rhizophora stylosa Griff.

TL;DR: Comparisons of watermotion measured in the field with rates of water motion in the laboratory incubations indicate that coral growth and reef development are influenced by the metabolic responses of corals to water motion over and around coral reefs.

TL;DR: A standard microwave oven for the sterilization of phytoplankton culture media and apparatus was tested and elimination of bacterial, algal, and fungal contaminants is achieved.

TL;DR: The use of energy-conversion factors based on AFDW is preferable due to their lower dispersion, and a general conversion factor of 23 J · mg−1 AFDW can be used for aquatic macrobenthic invertebrates.

TL;DR: When food is scarce, the ciliated band elongates relative to larval size through an increase in larval arm length relative to body length, and this plasticity may be an adaptation to variable food supplies in their natural environment.

TL;DR: It is concluded that the location of a seagrass bed within an estuary has a significant effect on abundances of juveniles of many species of fish and decapods, and the most likely cause of these effects is variation in distribution and availability of competent larvae.

TL;DR: In a reef environment dominated by visually oriented predators, the striking color pattern and behavioral responses of Hexabranchus may have arisen with a concomitant elaboration of dietarily derived chemical defenses.

TL;DR: The blue mussel Mytilus edulis is the first mollusc reported that is not induced to settle and metamorphose by elevated potassium ion levels.

TL;DR: Coral substratum was found to have much greater effects than competition on juvenile survival over a 1-yr period, with greater numbers of both fish species surviving on Pocillopora reefs, and the factors controlling growth and mortality are complex.

TL;DR: The results of a reciprocal transplant experiment showed that there was consistently greater settlement and recruitment on granite stones than on basalt stones at both shores, suggesting that larvae select granite over basalt substrata for settlement.

TL;DR: It is demonstrated that larvae entering the water column have a low chance of returning to their parent reef and that recruitment to some reefs from an upstream population was unlikely during a typical 3–7-day pelagic period because some populations were found to be hydrodynamically isolated from their neighbours.

TL;DR: The idea that mussel beds function as systems not just as populations of mussels which process estuarine materials is supported, as the magnitudes of material transports are generally higher on the mussel bed due to greater filter-feeder biomass, the existence of a substantial microbenthic algal component and a considerably different environmental setting.

TL;DR: The similarity of the deterrent effects of the compounds used in this study increases the validity of previous studies in the northeastern Pacific Ocean which correlate algal phenolic levels and diets or feeding preferences of invertebrate herbivores.

TL;DR: The data suggest that the growth rate as well as the degree to which this species can penetrate estuaries is partially determined by the amount of time which the mussels are able to spend in positive scope for growth under the estuarine conditions of reduced and fluctuating salinities.

TL;DR: Preliminary data suggest that survival may be enhanced in the presence of older conspecifics, and the discussion emphasizes the species-specific nature of the identified interactions, and cautions against treating guild members as a homogeneous group when examining patterns of recruitment.

TL;DR: Temperature clearly influenced fatty acid composition and levels of unsaturated fatty acids and ratios of (n−3)(n−6) fatty acids were highest at the lowest temperatures, and Levels of C and N per biovolume unit followed a pattern of temperature dependence similar to growth rate.

TL;DR: It is suggested that in an early stage of eutrophication, before an extensive increase in turbidity caused by phytoplankton, the microphytobenthos will benefit from increased nutrient levels and have a positive effect on the ecosystem by improving oxygen conditions at the sediment-water interface and by decreasing the release of inorganic nutrients from the sediment.

TL;DR: Visual surveys along subtidal belt transects indicate that the presence of a giant kelp forest may increase the abundance and species diversity of the fish assemblages over a high relief rocky reef in central California, U.S.A.

TL;DR: Results show that for Haliotis rubra Leach, on a spatial scale measured in 10s of meters, the abundance of recruitment is directly related toThe abundance of mature abalone.

TL;DR: Temperature had little effect on stage-specific survival of larval stages I and II but survival of stages III and IV was significantly reduced among lobsters reared at 10°C ( 75%) and a quadratic growth response to temperature revealed that the largest growth rates were at 15 and 18 °C.

TL;DR: This study investigated the feeding relationship between the ascoglossan Elysia halimedae Macnae and its preferred food, the seaweed Halimeda macroloba Decaisne, and isolated and determined the structure of the ascogslossan compound, a significant feeding deterrent at naturally occurring concentrations toward potential predators.

TL;DR: Results of this study suggest a possible association between senescence and protein metabolism in scallops, and serve to stress the importance of protein as an energy substrate in pectinids.

TL;DR: Phaeophorbides may represent good feeding markers for macrobenthic deposit-feeding processes and the amount of ingested chlorophyll that is converted to phaeopigments is dependent upon the quality of plant source materials and the interactions between coexisting species.

TL;DR: In this article, population dynamics of two benthic dinoflagellates, which have been implicated in ciguatera fish poisoning, were studied over a 3-yr period in southwestern Puerto Rico.

TL;DR: Spatial patterns in epibenthic mud dwelling copepods appears to be disrupted with each tidal cycle due to active or passive resuspension processes, and patterns vary with species and feeding mode (benthic or planktonic).

TL;DR: Field and laboratory experiments were used to determine the importance of the polychaete Nereis divero lower densities of thepolychaete had little or no impact on the emigration of the prey organism.

TL;DR: A spreading out of the risks is thus noted for the Brest population where the spawning, fractioned over several months, increase the global chances of success over the year, and at St. Brieuc, the success or failure of the main spawning is determinant for recruitment.
