The Effect of Alternative Forest Management Models on the Forest Harvest and Emissions as Compared to the Forest Reference Level
forest management models carbon sink forest harvest forest reference level production forests multifunctional forests set-aside forests
2024/1/22
Background and Objectives: Under the Paris Agreement, the European Union (EU) sets rules for accounting the greenhouse gas emissions and removals from forest land (FL). According to these rules, the a...
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...

2023/12/19
Inventories of tropical forest aboveground biomass (AGB) are often imprecise and sparse. Increasingly,?airborne?Light Detection And Ranging (LiDAR) and satellite optical wavelength sensor data are use...
Influence of Soil Properties on P Pools and Its Effect on Forest Productivity in Mediterranean Calcareous Soils
calcareous soils Mediterranean ecosystem phosphorus availability phosphorus fractionation semiarid environment sequential extraction
2023/12/11
Although soil phosphorus is essential for vegetation growth it is not always found in labile forms, hampering its absorption by plants, and is limited in forest ecosystems. This study explores soil P ...
Assessing Tree Coverage and the Direct and Mediation Effect of Tree Diversity on Carbon Storage through Stand Structure in Homegardens of Southwestern Bangladesh
traditional homegardens agroforestry system biodiversity and carbon optical remote sensing
2023/12/8
Dealing with two major challenges, climate change mitigation and biodiversity loss, under the same management program, is more noteworthy than addressing these two separately. Homegardens, a sustainab...
A systems genetics approach to deciphering the effect of dosage variation on leaf morphology in Populus
Populus leaf morphology plant genomes gene dosage morphological
2023/12/6
Gene copy number variation is frequent in plant genomes of various species, but the impact of such gene dosage variation on morphological traits is poorly understood. We used a large population of Pop...
Time-Lag Effect of Climate Conditions on Vegetation Productivity in a Temperate Forest–Grassland Ecotone
