CARBON STOCK GROWTH IN A SECONDARY ATLANTIC FOREST [PDF]

open access: yesRevista Árvore, 2019
The secondary Atlantic forests play an important role in the context of climate change, acting as a carbon sink for the atmosphere. However, these forests can become a carbon source in case of increased tree mortality.

Complex Physiological Response of Norway Spruce to Atmospheric Pollution – Decreased Carbon Isotope Discrimination and Unchanged Tree Biomass Increment

open access: yesFrontiers in Plant Science, 2016
Atmospheric pollution critically affects forest ecosystems around the world by directly impacting the assimilation apparatus of trees and indirectly by altering soil conditions, which subsequently also leads to changes in carbon cycling.

Impact of regional climatic conditions on tree growth on mainland Greece

open access: yesFolia Oecologica, 2019
Forest growth is commonly used to explore tree vitality and ability to resist to environmental changes or climatic fluctuations. This paper illustrates and examines how regional climatic conditions can be related to the decline of tree growth, which were

Select or Not? Comparing the Impact of Selective and Schematic Thinning on Scots Pine Tree Growth and Stand Structure

open access: yesForests, 2023
The first commercial thinning usually entails a high cost in harvest operations and a low resulting income. From a practical forestry perspective, a schematic spatial selection might be more efficient than a selective approach.

Variation in the diversity-productivity relationship in young forests of the eastern United States.

open access: yesPLoS ONE, 2017
The diversity-productivity relationship has not been studied as extensively in forests as in other ecosystems. We address this gap in our knowledge by examining the relationship of productivity (primarily the periodic annual increment in aboveground ...

Diameter growth prediction for individual Pinus occidentalis Sw. trees

open access: yesiForest - Biogeosciences and Forestry, 2013
Predictive equations calibrated with remeasurement data from 25 permanent plots having individually identified trees were used to project stem diameter of Pinus occidentalis Sw. in Dominican Republic. The general form of the models used to fit the growth

Competition Indices and Their Relationship With Basal Area Increment of Araucaria

open access: yes, 2018
Models that report the effect of competition are important for forest management since forests with higher levels of competition have lower increment rates, and their use is necessary to plan forest interventions.
