Does Motility-Restricting Fibrosis Influence Dispersal? An Experiment in Nature With Threespine Stickleback.

ABSTRACT: Dispersal can affect individual-level fitness and population-level ecological and evolutionary processes. Factors that affect dispersal could therefore have important eco-evolutionary implications. Here, we investigated the extent to which an inflammation and tissue repair response-peritoneal fibrosis-which is known to restrict movement, could influence dispersal by conducting a mark-recapture experiment in a lake in Alaska with threespine stickleback (Gasterosteus aculatus). A subset of captured stickleback were injected with aluminium phosphate to experimentally induce fibrosis ('treatment group'), and another subset were injected with saline or received no injection-both of which do not induce fibrosis ('control group'). We released all fish at one introduction point and re-sampl
