Radial Growth of Qilian Juniper on the Northeast Tibetan Plateau and Potential Climate Associations [PDF]

open access: yes, 2013
There is controversy regarding the limiting climatic factor for tree radial growth at the alpine treeline on the northeastern Tibetan Plateau. In this study, we collected 594 increment cores from 331 trees, grouped within four altitude belts spanning the

Tree growth and management in Ugandan agroforestry systems: effects of root pruning on tree growth and crop yield [PDF]

open access: yes, 2008
Tree root pruning is a potential tool for managing below-ground competition when trees and crops are grown together in agroforestry systems. This study investigates its effects on growth and root distribution of Alnus acuminata (HB & K), Casuarina ...

Lianas Suppress Seedling Growth and Survival of 14 Tree Species in a Panamanian Tropical Forest [PDF]

open access: yes, 2016
Lianas are a common plant growth form in tropical forests, where they compete intensely with trees, decreasing tree recruitment, growth, and survival. If the detrimental effects of lianas vary significantly with tree species identity, as is often assumed,

Juniper from Ethiopia contains a large-scale precipitation signal [PDF]

open access: yes, 2008
Most semiarid regions are facing an increasing scarcity of woody vegetation due mainly to anthropogenic deforestation aggravated by climate changes. However, there is insufficient information to reconstruct past changes in climate and to evaluate the ...

Above- and below-ground competition in high and low irradiance: tree seedling responses to a competing liana Byttneria grandifolia [PDF]

open access: yes, 2008
: In tropical forests, trees compete not only with other trees, but also with lianas, which may limit tree growth and regeneration. Liana effects may depend on the availability of above- and below-ground resources and differ between tree species.
