The Ecological Stoichiometry Cooperative (ESC) is aiming to address the need for a comprehensive stoichiometry database by building a new database called Stoichiometric Traits of Organisms In their Chemical Habitats (STOICH). The construction of this database is one of the main objectives of the ES Cooperative’s NSF-funded STOICH project.

The ESC aims to encourage community member contributions to the STOICH database. With each contribution, the breadth of this database will increase, as well as its value to scientists who use it. We are excited for the STOICH project to assist our community in addressing stoichiometric questions regarding ecosystems, communities, organisms, and evolution.
