Effects of Oscillatory Flow on Fertilization in the Green Sea Urchin Strongylocentrotus droebachiensis

Abstract: Broadcast spawning invertebrates that live in shallow, high-energy coastal habitats are subjected to oscillatory water motion that creates unsteady flow fields above the surface of animals. The frequency of the oscillatory fluctuations is driven by the wave period, which will influence the stability of local flow structures and may affect fertilization processes. Using an oscillatory water tunnel, we quantified the percentage of eggs fertilized on or near spawning green sea urchins, Strongylocentrotus droebach… Show more

“…This factor may explain why intertidal species are more genetically structured than subtidal species [34]. As ambient flow rates increase with the inflowing tide, the heterogeneous bathymetry resulting from the presence of local features, such as the plants themselves, rocks, boulders and changes in depth, give rise to increased turbulence which can effectively transport the newly released spores into the overlying water column [44]. Once the spores become buoyant, because of their small size (approx.…”

“…While hydrodynamic variability, such as differences in wave height and period or current speeds, are considered a major driver of species distributions (Denny, 2006), effects of hydrodynamics on species interactions are still understudied. Different hydrodynamic conditions can lead to changes in biotic processes such as altering growth rates (Millar et al, 2019), fertilisation success (Kregting et al, 2013), and nutrient uptake (Morris et al, 2008).…”
