ARDITI Roger

As a professor at AgroParisTech, I joined in 2008 the former UMR7625 'Ecologie & Evolution', heading the team 'Ecologie des populations et communautés'. In 2013, E&E merged into iEES-Paris and EPC merged into EERI. Since retirement in 2012, I pursue voluntary research, both at Sorbonne Université and at the University of Fribourg in Switzerland.

Recent work in theoretical ecology deals with
(1) mathematical modelling of the dynamics of fragmented populations,
(2) dimensions and units of various interaction strength indicators.

Publication lists can be found through Google Scholar, Publons, Orcid, ResearchGate, and other tools.

The main aspect of my contribution to basic ecology is the Arditi-Ginzburg theory of ratio-dependent predation, which is now presented in standard ecology textbooks (e.g., Begon et al. 2006, Gotelli 2008, Krebs 2009, Molles 2015), and which is comprehensively explained in our 2012 book:

R. Arditi & L.R. Ginzburg, "How Species Interact: Altering the Standard View on Trophic Ecology", Oxford University Press, 192 p., 2012.

Outside of the field of scientific ecology, I am also involved in historical research, namely in the history of the Ministry of Agriculture of the Vichy Regime (1940–1944).
