Other claims from this paper (8)
- Observation Eastern gray squirrels were absent from small or isolated patches and sites over 15 km from large riparian forests.
- Intervention effect Excluding Sciurus lowered seed survival compared with access by squirrels.
- Mechanism Fox squirrels may compensate through seed dispersal in watersheds without gray squirrels.
- Association Seed survival was extremely low in low-production years.
- Association Seed survival was higher and varied by seed type in high-production years.
- Association Rodents dispersed seeds farther in seed-poor than seed-rich years.
- Association Rodents dispersed more energy-rich food items farther.
- Method / resource Seed removal rate did not adequately index seed predation rate.
