DESCRIPTION:One equation helps solve three paradoxes in the spatial ecology
  of predators and prey\n\nMark Lewis\, University of Victoria\n	Tuesday Apr
 il 15\, 12-1pm\n	Zoom Link: https://mcgill.zoom.us/j/89914150820\n	In Person
 : 550 Sherbrooke\, Room 189\n	\n	Abstract: In this talk I will introduce thr
 ee paradoxes in the spatial ecology of predators and prey (1) Buffer Zone 
 Paradox: Why to wolves maintain stable buffer zones for prey\, even though
  they may be only saving prey for the neighboring packs? (2) Road Use Para
 dox: Why are wolves attracted to roads and related linear features\, even 
 though that can mean higher chances of dying? (3) Path Less Travelled Para
 dox: Why do wolves preferentially travel to places they haven’t been recen
 tly\, even if it means fewer prey? To help solve these paradoxes\, I will 
 start with the Fokker-Planck equation\, which describes the probability de
 nsity function for an individual undergoing a random walk. I will then emp
 loy a mixture of mathematical approaches including nonlinear advection-dif
 fusion\, differential games\, first passage time theory and stochastic pro
 cesses. All of the resulting models will be fit to data before drawing sci
 entific conclusions.\n
