Appendix C - Presenting STOC case study with biomod2 v4.3-4
收藏资源简介:
To illustrate the different features of biomod2, both existing and new, this tutorial presents a case study with count data. The example dataset comes from the French Breeding Bird Survey (STOC program) of Vigie-Nature (Fontaine et al. 2020). The original dataset contains 2,948 sites in which more than XX bird species have been observed from 2001 to 2024. Original raw data is not provided here, but might be made available on request by contacting Benoît Fontaine (benoit.fontaine@mnhn.fr). Specific sub-dataset has been built for this example, and the data has been integrated to the biomod2 package and can be access through data(DataSTOC) command. 20 bird species present in 1,003 sites have been kept, and their yearly average headcounts have been computed over 2 time periods: 2006-2011 and 2012-2017. These periods ensure both the match with environmental variables availability (especially CORINE habitats, see after) and sufficient records. 6 explanatory variables have been extracted for each site coordinates: annual mean temperature and precipitation (from CHELSA), percentage of agricultural, water and wetland habitat cover around each point (from European Union’s Copernicus Land Monitoring Service information) and Shannon habitat diversity (from CORINE). An example of Material and Methods paragraph, describing this present example, is available below. Italic sentences do not relate directly to this dataset, but have been included for the sake of completeness of the various steps of the modelling workflow. All data and code used for this example are presented here. Original data DATA_biomod2_STOC.csv Dataset used in the example and obtained from STOC.Dataset is also available directly within biomod2 package through data(DataSTOC) command.
