Abstract Impacts of climate warming on forests vigour are forecasted to increase in magnitude. Yet it remains unclear how stand characteristics and competition modulate the relationship between tree growth gross primary production with drought. Here, we studied spatial variation density, basal area height modulates (Basal Area Increment, BAI growth), summer NDVI, as well their responses drought...

‏ This experiment was conducted to determine the performance and intestinal microflora population of broiler chicks in diets supplemented with Roxarsone, Avilamycin and Formycin gold during starter period. A basal diet was formulated according to NRC (1994) recommendation for starter (0-21 d) period and also supplemented with appropriate amounts of the mentioned growth promoters. Each of the tr...

Global climate is changing due to increasing anthropogenic emissions of greenhouse gases. Forest managers need growth and yield models that can be used to predict future forest dynamics during the transition period of present-day forests under a changing climatic regime. In this study, we developed a forest growth and yield model that can be used to predict individual-tree growth under current ...

Modification of stands’ structure and managing them using silvicultural methods close to nature and single selection system require information on status of structure, determining the target diameter, basal area and suitable volume to result in long-term equilibrium and sustainability. So, this study was conducted using the selection sample statistical method by selecting  five 1-ha sample plot...

Quantifying forest growth and determination of its affective factors are fundamental for forest management. This study examines the effects of biotic and abiotic factors on the diameter increment of oriental beech (Fagus orientalis Lipsky) in a high-elevation forest in northern Iran using permanent sample plots. The aim of this study was identification and quantifying environmental factors such...
