The effect of tree age, size and competition on above ground growth allocation was studied with 69 Pinus sylvestris trees. Competition was described by tree-level indicators (needle density, crown ratio and height-diameter ratio). The stem, branch and needle growth were determined by stem and branch radial increments and tree level biomass analysis. Combined growth of compartments was strongly ...

Flood regime and vegetation flood tolerance interact to influence tree growth in riverine landscapes. We studied tree growth in floodplain and upland forests of theWisconsin River. About a century ago, levees set back from the river were constructed on this floodplain. The levee restricts some floodplain area from overbank flood events, but leaves a portion of active floodplain still inundated ...

This study was conducted in the Kordofan region of Sudan during 2011–12. It was devoted to the morphology associated to the juvenile development and performance of tree species of Capparaceae and Combretaceae in a nursery and early field growth. The nursery experiment was conducted to study morphological characters to identify seedlings of tree species under study. Seedlings were transplanted t...

Nutrient enrichment is increasingly affecting many tropical ecosystems, but there is no information on how this affects tree biodiversity. To examine dynamics in vegetation structure and tree species biomass and diversity, we annually remeasured tree species before and for six years after repeated additions of nitrogen (N) and phosphorus (P) in permanent plots of abandoned pasture in Amazonia. ...

Climate change is challenging forestry management and practices. Among other things, tree species with the ability to cope with more extreme climate conditions have to be identified. However, while environmental factors may severely limit tree growth or even cause tree death, assessing a tree species' potential for surviving future aggravated environmental conditions is rather demanding. The ai...

Comparison of the historical and spatial precipitation and tree growth patterns confirm that one of the limiting conditions to growth on southern Vancouver Island is moisture, both as it relates to precipitation as well as the position of the tree within the slope catena. Comparison of tree growth patterns with AVIRIS reflectance indicates that there is correlation between the growth increment ...
