Biodiversity modelling.

Any SDM or biodiversity analysis starts with the conceptualisation of one or several underlying questions and related hypotheses. These conceptual considerations should be summarised in the Overview section, which captures the skeleton of the analyses, providing enough information for readers to understand the model setup and workflow (Guisan and Zimmermann 2000, Austin 2002, 2007).

The Decade aims to gather the science and best practices on ecosystem restoration and encourage action. Therefore, it is unlikely that any one approach to biodiversity modelling and prediction will outperform other approaches in all situations (Ferrier & Guisan, 2006). With respect to the challenges identified above, it is beneficial to incorporate the strengths of multiple modelling strategies to handle the multifacets of biodiversity.Just as diversity celebrates differences among groups of people, biodiversity concerns the differences among species in the natural world.
