 WELCOME TO The Algae & Grazers Research group webpage

The Algae & Grazers Research Group is an interdisciplinary team of researchers from the School of Biological Sciences and Department of Mathematical Sciences at the University of Essex.

 

The oceans contain only about 0.5% of total global biomass of primary producers. However, they provide a similar amount of total annual production to that on land and turnover times for organic matter is 1000-times faster in marine in comparison to terrestrial ecosystems.

 

The Algae & Grazers Research Group is involved in a range of research areas from microzooplankton and copepod behavioural ecology and population modelling to phytoplankton trace gas production under different climate change scenarios.

 

Our research interests include:

DMSP & DMS Production & Biogeochemistry

Quantification of Real Time Trace gas production

Mathematical Modelling in Biology and Ecology

Production of biogenic trace gases under future CO2 levels

Plankton Chemical Ecology & Trophic Interactions
