Does Ungulate Foraging Behavior in Forest Canopy Gaps Produce a Spatial Subsidy with Cascading Effects on Vegetation?

Concentrated foraging in forest canopy gaps by large ungulates may produce a pulsed spatial resource subsidy with cascading effects on the composition and developmental trajectory of gap vegetation. To test this hypothesis, we investigated the influence of white-tailed deer (Odocoileus virginianus) use of 12 artificial canopy gaps in a hemlock-northern hardwood forest. Ground-layer vegetation was monitored and available reactive nitrogen was...
