Epiphytes growing on seagrass leaves increase productivity and add food for grazers to the ecosystem.

The response of Pacific Northwest (PNW) Z. marina to interactive effects of temperature and nitrogen conditions was experimentally evaluated. . . . Temperature played a dominant role controlling Z. marina response to nutrients; nitrogen toxicity was not observed, and in general the effects of temperature and nutrients were not synergistic. This work highlights the complex nature of Z. marina response to environmental conditions; additional multifactor experiments will be required to tease apart these interactions."
