A Bayesian Approach to Estimating Seemingly Unrelated Regression for Tree Biomass Model Systems
Bayesian approaches seemingly unrelated regression Korean larch Markov chain Monte Carlo Gibbs sampler
<
2024/1/19
Accurate estimation of tree biomass is required for accounting for and monitoring forest carbon stocking. Allometric biomass equations constructed by classical statistical methods are widely used to p...
Allometric Biomass Model for Aquilaria Malaccensis Lam. in Bangladesh: A Nondestructive Approach
Allometry Aquilaria malaccencis biomass biomass expansion factor
<
2023/12/18
Aquilaria malaccensis Lam. is an important commercial tree species of Bangladesh. This species is widely planted for the increased demand for an essential oil locally knows as "Agar". A nondestructive...
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...
An approach to quantify natural durability of Eucalyptus bosistoana by near infrared spectroscopy for genetic selection
Eucalyptus near infrared spectroscopy genetic selection
<
2023/6/5
Natural durability within a timber species can be variable. Hence efficient assessments of natural durability are required to ensure quality either through tree breeding or segregation during producti...
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...
Adaptive k-tree sample plot for the estimation of stem density: An empirical approach
plotless sampling distance sampling bias efficiency forest sampling
<
2018/3/6
Available budgets for the inventory of non-commercial woodlands are small. Therefore, there has been increased
interest in using distance methods, such as k-tree sampling, which are faster than fixed...
Modelling individual tree diameter growth for Norway spruce in the Czech Republic using a generalized algebraic difference approach
base-age invariant approach Chapman-Richards function global parameters tree-specific parameters iterative nested regression National Forest Inventory
<
2017/6/26
Individual tree-based growth models precisely describe the growth of individual trees irrespective of stand complexity. These models are more useful than the stand-based growth models for effective ma...
Development of models for forest variable estimation from airborne laser scanning data using an area-based approach at a plot level
Python Fusion forest inventory linear regression Norway spruce
<
2016/4/6
Airborne laser scanning (ALS) is increasingly used in the forestry over time, especially in a forest inventory process. A great potential of ALS lies in providing quick high precision data acquisition...

This study focuses on using an ecosystem approach for forestland classification of the Liukuei Experimental Forest of Taiwan
Forestry Research Institute. The content includes the delineation of ecos...
Generalized additive models as an alternative approach to the modelling of the tree height-diameter relationship
nonparametric method Norway spruce Petterson function
<
2015/7/2
Generalized additive models were tested using three types of smoothing functions as an alternative for
modelling the height curve. The models were produced for 23 forest stands of Norway spruce (Pic...
Analysis of operational approach during forest transformation in Klokočná Range, Central Bohemia
stand transformation harvest diameter distribution
<
2015/5/18
In this study immediate results concerning the effectiveness of the applied silvicultural measures in the
course of forest transformation were analysed.
Multivariate statistical approach to comparison of the nutrient status of Norway spruce (Picea abies [L.] Karst.) and top-soil properties in differently managed forest stands
humification nutrition cation exchange capacity (CEC)
<
2015/3/6
The soil is an irreplaceable component of forest ecosystems. Soil-forming processes directly influence element cycling (EC). Plant-soil interaction is a specific part of EC. Plant-soil interactions we...
Logistic regression approach to the prediction of tree defoliation caused by sawflies (Hymenoptera: Symphyta)
