e0“When Sciurus was excluded from seeds, seed survival was much lower than when these species could access seeds.”
e1“The seeds of oaks (Quercus), hickories (Carya), and walnuts (Juglans) are dispersed by rodents”

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.
- Observation Seedling recruitment was not reduced where eastern gray squirrels were absent.
- 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.
