DESCRIPTION:How do we define a patch? Deriving subpopulation structure from
  movement models using random-walk-based distance metrics\n\nEric Pedersen
 \, Concordia University\n	Tuesday October 31\, 12-1pmZoom Link: https://mcg
 ill.zoom.us/j/86855481591In Person: 550 Sherbrooke\, Room 189Abstract: The
  metapopulation framework is a cornerstone tool for modelling spatially st
 ructured populations. A metapopulation is defined as a set of subpopulatio
 ns living in well-mixed patches\, connected by inter-patch movement. Howev
 er\, there is currently no clear single definition of what constitutes a “
 patch” of habitat in fragmented and heterogeneous landscape. In this talk\
 , I argue that we should define patches based on synchronization of popula
 tion dynamics driven by local interactions between individuals. Further\, 
 when interaction is driven by individual patterns of movement and movement
  follows a Markov random walk\, I show that it is possible to derive a mea
 sure of lifetime encounter probabilities between individuals inhabiting th
 e landscape. This can be used to define a consistent metric for clustering
  locations on a landscape based on patterns of encounter probability. I de
 monstrate an eigenvector- based approach to approximating this metric for 
 large complex landscapes\, and show how this approach works for clustering
  simulated landscapes and spatially structured marine habitat of Northern 
 Shrimp in northern Atlantic waters in Canada.\n\nContact Information\n\nEm
