Research Abstract
In this study, we attempted to compare the distance of seed dispersal between brown bear habitat and non-habitat areas. In one brown bear habitat area, mountain grape (Vitis coignetiae) seeds were established more than 10 km away, suggesting that there is long-distance seed dispersal in brown bear habitat areas. Because we could not successfully estimate seed dispersal distances in areas without brown bear habitat, we did not know whether the presence or absence of brown bears affects the distance of seed dispersal in V. coignetiae. However, because there were no distinct differences in the genetic diversity of mountain grape between areas inhabited by brown bears and areas not inhabited by brown bears, we inferred that, at least on long time scales, differences in animal seed disperser communities do not affect the rate of plant dispersal.
