John Taylor

I am an aquatic ecologist/ecotoxicologist with an interest in how ecosystem changes affect aquatic trophic ecology and how food web changes can alter contaminant cycling in aquatic biota and habitats.

My current position is in the Ecosystem Analysis Unit of the SLU Coastal Laboratory where my main duties are to asstist with national and international projects aiming to improve the sustainable management of aquatic environments.

Previsouly, I have studied how a changing Baltic Sea (such as an increase in cyanobacteria blooms) has affected the growth of Baltic herring, and how this change in growth has altered the cycling of persistent organic pollutants within the herring.
