Insect herbivores increase mortality and reduce tree seedling growth of some species in temperate forest canopy gaps [PDF]

PeerJ, 2017
Insect herbivores help maintain forest diversity through selective predation on seedlings of vulnerable tree species. Although the role of natural enemies has been well-studied in tropical systems, relatively few studies have experimentally manipulated ...

Tree regeneration and spatial patterning among midtolerant tree species following gap-based harvesting in a temperate hardwood forest

Frontiers in Forests and Global Change, 2023
IntroductionField experiments of gap-based harvest systems in temperate northern hardwood forests have provided inconsistent support for the theory that such regeneration approaches can improve regeneration success among increasingly underrepresented ...
