New article on optimal movement

November 4, 2013

My first article on optimal behavior in patchy habitats has just been published online in the Journal of Mathematical Biology. It is available in Open-access from the journal :

How optimal foragers should respond to habitat changes: a reanalysis of the Marginal Value Theorem

Vincent Calcagno, Ludovic Mailleret, Éric Wajnberg, Frédéric Grognard

This is the first of a series of articles (which we informally call the “Charnov series”) where we revisit the celebrated Marginal Value Theorem from Charnov (1976), proving and expanding the theoretical predictions. In particular, we work out the adaptive consequences of habitat heterogeneity (i.e. resource distribution) on individual fitness and on the optimal rate of movement.

Modelling workshop in Oléron, September 24-27

September 6, 2013

The interdisciplinary group M3D organizes its 2013 workshop on the beautiful island of Oléron, on the French Atlantic coast.

I’ll be giving a mini-course on the implicit modelling of spatial structure for ecological systems.



CSEE meeting in Kelowna, next month

April 12, 2013

I won’t be able to attend the meeting unfortunately, but Renato Henriques- Silva will be presenting the PhD research he is doing in the Peres-Neto lab at UQAM, Montreal. He is modelling the evolution of flexible dispersal strategies in a network-metapopulation context. Go see his talk if you have the luck to be in Kelowna!

The structure of spatial networks influences dispersal evolution“, Tuesday 14th, 11:15am, room EME1101


Outreach articles on submission flows

February 28, 2013

In two forthcoming articles, we explain and discuss (in French!) our results on manuscripts submission flows. One has just been published online in the latest issue of Medecine/Sciences, the other is to appear soon in Virologie, with a closer look at selected journals from this field.




Stat course in Sophia: February 11-14

February 7, 2013

The course will take place at the Molecular & Cellular Physiology Institute (IPMC) in Sophia-Antipolis, room B07 (IPMC2 – R-1):
