Risk Academy, led by the Nexus Consortium · Earth and Environmental Sciences

Biodiversity and ecosystems

The discipline covers the condition of species, genetic diversity and ecosystems, the services people draw from them and the risks their decline creates for societies and economies.

03The discipline

The field and its scope

For ecologists, conservation planners, environmental assessors and analysts of nature-related risk who need to read an abundance index, a Red List category or a species distribution model and know what it rests on.

04Measures

Quantities and units

05Methods

Methods and their limits

Each method is listed with what it assumes and where it fails.

06Debates

What the field debates

07Bodies and data

Bodies that set practice, and the data they publish

Bodies and standards are named so learners can find and apply their published work; the Academy teaches their use and links to the publisher, and no affiliation is implied.

08Simulator

Run the discipline's simulator

Biodiversity and ecosystems's own model, as a live chart: move each parameter and read how the outputs respond.

09Maps

Maps and the globe for any place

Search any place or open the world; the layers and generators follow biodiversity and ecosystems on the planet map, the globe and in 3D.

The boundaries, names and designations shown do not imply any judgement on the legal status of any territory, or any endorsement or acceptance of such boundaries. Countries: Natural Earth (public domain).
