Welcome to the ES Cooperative’s STOICH Project Website!

The STOICH Project: Stoichiometric Traits of Organisms in their Chemical Habitats


the quantitative relationship between constituents in a chemical substance

Ecological Stoichiometry

the study of the balance of energy and multiple chemical elements in ecological interactions

Exploring broad-scale, aquatic, ecological questions using stoichiometry

We are the Ecological Stoichiometry Cooperative, a team of researchers whose goal is to synthesize existing and new datasets on the ecological stoichiometry of inland waters.

Our collective research aims have given rise to the STOICH project.

We are creating an open-source, stoichiometric database (STOICH) to answer broad-scale, aquatic, ecological questions.
