First good news: Rebekka’s (PhD student in Justin Travis‘ group) first paper has been accepted by Ecography! Here we present a theoretical model for the evolution of dispersal along a linear environment with a unidirectional current (e.g. a river). We show that a combination of natural selection and spatial sorting generates and maintains downstream gradients in dispersal propensity, where individuals from upstream populations tend to be substantially more philopatric.
Second good news: a fun collaboration led by Nick Synes and Aurore Ponchon using RangeShifter to assess the effectiveness of alternative conservation actions in facilitating range expansion and patch occupancy for virtual species. Now accepted in Biological Conservation!
