During the 1980s, reforestation programs using exotic species (Pinus spp.) were established in the páramo ecosystem of Ecuador. The aims of this study were: (1) to compare the natural regeneration bet...
Importance of stand structure and neighborhood in European beech regeneration
Fagus sylvatica Seedlings Saplings Closed canopy Ontogeny Competition Understory
2024/3/8
The European beech (Fagus sylvatica L.) is a competitive and shade-tolerant species, with its natural regeneration in closed-canopy stands affected by a number of variables. The study aimed to identif...

Prevalence of Tree Regeneration by Sprouting and Seeding Along a Rainfall Gradient in Hawai’i
feral pig disturbance Sus scrofa tropical dry forest tropical wet forest
2015/11/13
Drought stress in tropical dry forests is thought to result in greater asexual regeneration via vegetative sprouting (e.g., basal, root, and branch layering) than occurs in
moister tropical forests. ...
