MICE (Models of Intermediate Complexity) is a type of ecosystem model that is question-driven, and contains a limited number of components and ecological processes.

At NIWA, we consider all components of the marine ecosystem important when trying to better understand the role of dynamic, ecosystem processes on the distribution and abundance of marine organisms in New Zealand’s marine environments.

Approximately 500 Aquatic invertebrate taxa are described in this database, made available to assist with the identification of specimens.
