Background The spatial distribution of spawners and temporal parameters of spawning in motile invertebrates with external fertilization might influence reproductive success. However, to date, data on the prespawning and spawning behaviors of broadcas

Background In the predator–sea urchin–macrophyte trophic cascade, the ecological effect of sea urchins as grazers depends both on their density and the changes in foraging activity, which are influenced by various disturbing factors. However, the

Simultaneous video recording of the sea urchin spawning behavior and recording of environmental factors enabled us to found synergism of the effects of circadian rhythm and phytoplankton on the spawning activity of the sea urchin Strongylocentrotus i

The natural populations of the sea urchin Strongylocentrotus intermedius were studied along 350 km of the coast of the Primorye region of Russia (northwestern Sea of Japan). Most of the surveys were carried out in Kievka Bay, where sea urchins were s

Usin seven allozyme loci as gene markers, we studied the genetic structure of ten natural popula� tions of the sea urchin Strongylocentrotus intermedius in the northwestern Sea of Japan that differ in the pro� portion of individuals with differen
