Social Traveling Inferred from Multiple Captures: Testing Assumptions

Abstract

Live-trapping studies in which aspects of social behavior in rodents are inferred from multiple capture data assume that there is no bias introduced by the trapping mechanism. We document differences in springing weights of Sherman traps m the field, and show that more deer mice are captured in traps that have lower springing weights. Multiple captures need not occur as a result of social traveling, but could result from random nonsynchronous entry of mice into insensitive traps.
