Species distribution modelling (SDM) is a key competence for ecogeographical research and applied nature conservation. It allows researchers to estimate current distributions of species and to also predict their future distributions under climate change scenarios. SDM encompasses various area-wide spatial predictions techniques and requires profound skills related to organizing, handling, analyzing and visualizing geodata.
By using the programming environment R, this course will open the door to the cosmos of SDM techniques and will provide a flexible baseline for workflow automation in various research projects. Special emphasis will be on R Markdown and GitHub for proper documentation and reproducibility.
Intended learning outcomes
At the end of this course you should be able to
- feel comfortable with the usage of R and GitHub,
- distinguish between and apply major SDM techniques,
- analyse, share and reproduce your spatial data with R Markdown,
- use open GIS to manage, visualize and georeference your spatial data,
- include and process remote sensing data in your workflow,
- learn how to implement a research project in a collaborative approach, and last but not least to
- critically evaluate your analyses and results.
This course is intended as a blended learning module in our study program although the provided introductions, explanations and examples might be useful for self-study, too. Given the enormous body of literature and methods available for SDM, it can only be an entry point for more sophisticated and project-specific modelling techniques. Each course aims to create area-wide species distribution maps for a group of organisms and a particular area of the world for which hitherto no species richness maps exist.
This course will take place in a hybrid setting (except for the first session) with a digital classroom and additional students being present in person in the physical classroom (F 14 | 00A12). Details on this synchronous hybrid classroom format will be provided in the first session, which will take place in presence only on Tuesday 19.04.2022 at 10:15 am. The link to the digital classroom will be provided in the Ilias course environment (only accessible for members of the course who are logged-in into Ilias). Please also seriously check and follow the Information on the Coronavirus of the University of Marburg.
Tuesdays 10:15 - 12:45.

Preparation and prerequisites
Basic knowledge of R and of handling spatial data is beneficial, but not required. All software needed for this course is free and open source.
This course uses additionally provided material for teaching basic R skills, which can be found here.
