Secondly, the results of an analysis can be interpreted scientifically in terms of the hydrodynamics of the seas and their responses to tidal forcing. WebWe explored the effect of tidal vertical advection on the vertical distribution of bivalve larvae through a combination of ﬁeld sampling, simulation modeling, and a meta-analysis. This approach reﬂected an evolution of our thinking about the problem, and each component was devised in response to the results from the preceding component.

"WebBivalve sperm have two flagellae. Most eggs are small, and synchronized spawning results in the discharge of both types of gametes into the sea for external fertilization. Hermaphrodites usually bring in sperm from another individual through the incurrent siphon. The embryos are then brooded, and brooding typically occurs within the ctenidia.
