New Zealand winters are a month shorter than they were 80 years ago, NIWA scientists say.“This is a consequence of rising temperatures around the globe, and such trends in colder temperatures and frosts will influence the life cycle of plants and animals” - Dr Brett Mullan.

Unlike other ecosystem models, machine learning is built solely from the information it is presented.

Ecopath with Ecosim (EwE) is trophodynamic modelling software that uses a mass-balance approach to describe ecosystem based, marine food web interactions.

LIEM synthesizes field measurements with a priori knowledge of ecosystem structure and physiological capabilities, to constrain material flows through an ecosystem.

Spatially explicit disturbance/recovery models are a cellular automaton that uses a mechanistic approach to investigate recovery rates of benthic species following disturbance events.

Resource trade-off models are spatial models that use biological, environmental and socio-economic data to optimise management (protected area designation) across potentially conflicting uses, or across different ecosystem services.

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.

A weekly update describing soil moisture across the country to help assess whether severely to extremely dry conditions are occurring or imminent. Regions experiencing these soil moisture deficits are deemed “hotspots”. Persistent hotspot regions have the potential to develop into drought.
