New article on optimal movement

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.
