Abstract Details

2009, Master of Sciences, Case Western Reserve University, Biology.
Canopy influence has been proposed to explain the co-dominance of American beech and sugar maple in temperate forest canopies. I hypothesized that recruitment of young beech and sugar maple stems differs beneath conspecific and heterospecific canopy adult trees and may be confounded by environmental factors or forest fragmentation. In three fragmented forest stands, I measured density and stem morphology of seedlings and beech root sprouts <2.5 cm dbh in plots positioned beneath beech and sugar maple adult trees. Mean density and stem morphology of young beech and sugar maple plants were not influenced by canopy adult tree species type. However, abiotic and biotic environmental factors, as well as distance from a forest edge, had species- and age-dependent effects on seedlings and root sprouts. I conclude that differential species responses to environmental factors at young life history stages”and not canopy influence”mediate the coexistence of beech and sugar maple.
