In mixed forests, the presence of several tree species with various ecological characteristics leads to complex stand dynamics driven by the species-specific resource-use efficiencies that ultimately drive forest productivity. In this study, we applied the concept of stand growth dominance (GD), together with the growth rates of trees as a function...

The Altai Mountains in Northwest China has a great potential for dendroclimatological studies. Dendrochronological and climatological response analysis potentials of the northwest China Altai Mountains are hitherto unexplored. In this study, for the first time we have developed chronology statistics and climate response growth analysis of Pinus sib...

Accurate measurements of ring-width series are essential for dendrochronological analyses. We present an R package MtreeRing for ring-width measurements on scanned digital images. A morphological alternate sequential filter is used for noise reduction in the original image. Ring boundaries are determined by the steepest negative slopes in the light...

This research investigated and compared the primary and secondary forests in the ecological core area of Hainan Island to provide information for forest restoration. The secondary forest was in the early successional stage, and the comparative analysis was about species composition, forest structure and species biodiversity. The result showed signi...
