Fig. 2From: Diffusion modeling reveals effects of multiple release sites and human activity on a recolonizing apex predatorTime series of total abundance estimates from the spatiotemporal model of sea otter population growth and spread in Southeast Alaska. Points are posterior means, and segments are 95% credible intervals. Note region-wide surveys were completed over two years for the years 2002–2003 and 2010–2011Back to article page
