From: Multi-species genetic connectivity in a terrestrial habitat network
Population graphs representing the genetic relationships among 34 sites of fisher (Pekania pennanti, a), 28 sites of Canada lynx (Lynx canadensis, b), 29 sites of American marten (Martes americana, c), and 8 sites of southern flying squirrels (Glaucomys volans, d) in Ontario, Canada. Node size is proportional to node centrality and edge length is proportional to the genetic distance between populations
