Biomass and Volume Modeling along with Carbon Concentration Variations of Short-Rotation Poplar Plantations
biomass additivity Populus spp quantifying carbon stock short-rotation coppice stem volume equations
2024/1/22
Short-rotation forestry is of interest to provide biomass for bioenergy and act as a carbon sink to mitigate global warming. The Poplar tree (Populus × xiaohei) is a fast-growing and high-yielding tre...
Modeling Biomass and Nutrients in a Eucalyptus Stand in the Cerrado
non-linear model Schumacher–Hall model aerial biomass nutrient cycling
2024/1/19
The prediction of biological processes, which involve growth and plant development, is possible via the adjustment of mathematical models. In forest areas, these models assist in management practices,...
Use of Optimization Modeling to Assess the Effect of Timber and Carbon Pricing on Harvest Scheduling, Carbon Sequestration, and Net Present Value of Eucalyptus Plantations
timber harvest scheduling mixed-integer programming harvest age carbon sequestration
2023/12/19
Quantifying the impact of carbon (C) and timber prices on harvest scheduling and economic returns is essential to define strategies for the sustainable management of short-rotation plantations so that...

CONSERVATION RESOLUTION FOREST AREAS DIVERSITY INVASIONS PATTERNS SHIFTS BRAZIL HOOK
2023/12/18
Climate is the dominant control factor on the spatial distribution of organisms on a global scale and global warming is predicted to become a major cause of species extinctions. In our study ecologica...
Unmanned?aerial?vehicles (UAV)-based canopy height modeling under leaf-on and leaf-off conditions for determining tree height and crown diameter (case study: Hyrcanian mixed?forest)
canopy height model digital elevation model forest inventory unmanned aerial vehicles (UAVs) tree crown architecture
2023/12/1
Tree height and crown diameter are two common individual tree attributes that can be estimated from unmanned aerial vehicle (UAV) images thanks to photogrammetry and structure from motion. This resear...
Modeling Tree Growth Responses to Climate Change: A Case Study in Natural Deciduous Mountain Forests
biotic and abiotic factors climate change Hyrcanian Forest machine learning RCP scenarios
2023/11/22
Climate change has significant effects on forest ecosystems around the world. Since tree diameter increment determines forest volume increment and ultimately forest production, an accurate estimate of...
Modeling the effect of rockfall on forest development in a dynamic forest landscape model
disturbance dynamic forest modeling meta-model protection forest rockfall rockfall-forest feedback TreeMig
2023/11/20
Mountain forests below rocky cliffs are regularly impacted by falling blocks. Rockfall thus increases tree mortality and can locally alter the forest structure. At the same time, trees can decelerate ...

2023/11/20
Species distribution models (SDMs) are currently the main tools to derive species niche estimates and spatially explicit predictions for species geographical distribution. However, unobserved environm...
Modeling the Carbon Cycle of a Subtropical Chinese Fir Plantation Using a Multi-Source Data Fusion Approach
process-based terrestrial ecosystem model model–data fusion multi-source data carbon cycle plantation
2024/2/5
Process-based terrestrial ecosystem models are increasingly being used to predict carbon (C) cycling in forest ecosystems. Given the complexity of ecosystems, these models inevitably have certain defi...
