Course schedule & structure § Loïc and I teach a similar course at ETH since 2 years, covering approx. the domain of the introductory course. § In this course we introduce the basic statistical methods and some important conceptual constraints on how to build species distribution models (SDMs). § This introduction covers the methods GLM, GAM and CART, and also introduces methods to evaluate models and covers some important decisions. § Other, more advanced methods are not covered in the introduction, as these almost all go back to one of the three basic methods.

What limits the spatial distribution of species? Introductory course in Species Distribution Modelling using R @ PKU, Beijing, China Loïc Pellissier, Marc Grünig Philipp Brun & Niklaus E. Zimmermann | 6/13/2022 | 7

What limits the spatial distribution of species? Some important aspects § Most species have restricted distributions § Most species do not occur everywhere § Most species do not occupy all suitable habitat § Most species occur in the tropics Gaston (2003) The structure and dynamics of geographic ranges.
