You use a dye that works well under most conditions, but you do not realize that your study area is subject to acid rain. After you release the marked frogs, a heavy rain occurs and any frog not under a shelter during the rain will lose its dye mark. If when you recapture frogs, the frogs are a mix of marked individuals who have kept their mark, marked individuals who have lost their mark due to rain, and unmarked individuals, then your estimate of population size will likely be unaffected by the change in marking smaller than expected larger than expected
