Microcosm experimental evidence that habitat orientation affects phytoplankton-zooplankton dynamics

Abstract Although spatial ecology has achieved a great success in the passing decades, the importance of habitat orientation has not been well studied, especially for its effects on prey-predator dynamics. Here, we examined the responses of zooplankton activity and grazing rate to habitat orientatio...
