2021-10-01Teil eines BuchesIs there a size-dependency in the predator- prey interaction of Asterias rubens and Mytilus edulis? This study examines the complex structure of prey and predator interactions, which are regulated by a variety of factors. Here, we are focusing on the prey size preference of the starfish Asterias rubens and its prey, the ...
