Tree height-diameter allometry and implications for biomass estimates in Northeastern Amazonian forests [PDF]

PeerJ
The relationship between tree height and diameter varies across forest types, introducing uncertainties in height that can affect aboveground biomass estimates in tropical forests. Here, we used a four-step approach to assess whether incorporating height

Integration of tree allometry rules to treetops detection and tree crowns delineation using airborne lidar data

iForest - Biogeosciences and Forestry, 2017
Airborne laser scanning (ALS) has recently gained increasing attention in forestry, as ALS data may facilitate the efficient assessment of forest inventory attributes and ecological indicators related to forest stand structure.

Dynamic carbon allocation trade‐off: A robust approach to model tree biomass allometry

Methods in Ecology and Evolution
Forest above‐ground biomass (AGB) is often estimated by converting the observed tree size using allometric scaling between the dry weight and size of an organism. However, the variations in biomass allocation and scaling between tree crowns and stems due

Multi-scaling allometry in human development, mammalian morphology, and tree growth [PDF]

Scientific Reports
Various animal and plant species exhibit allometric relationships among their respective traits, wherein one trait undergoes expansion as a power-law function of another due to constraints acting on growth processes.

Allometry of the quasi-pipe (qPipe) model for estimating tree leaf area and tree leaf mass applied to plant functional types

Scientific Reports, 2023
The allometry of the pipe model quantifies the approximate proportionality between the tree leaf amount and the stem cross-sectional area at the crown base (A CB).

Stand Structure Impacts on Forest Modelling

Applied Sciences, 2022
Modelling is essential in forest management as it enables the prediction of productions and yields, and to develop and test alternative models of silviculture.

Developing nondestructive species‐specific tree allometry with terrestrial laser scanning

Methods in Ecology and Evolution, 2023
Allometric equations predict organism attributes from simple measurements and underlie many global‐scale estimates, from plant productivity to ecosystem carbon stocks. In forests, destructive harvesting of trees in common groups (e.g.

Edge effects on tree architecture exacerbate biomass loss of fragmented Amazonian forests

Nature Communications, 2023
Habitat fragmentation could potentially affect tree architecture and allometry. Here, we use ground surveys of terrestrial LiDAR in Central Amazonia to explore the influence of forest edge effects on tree architecture and allometry, as well as forest ...

Modelling tree height-diameter allometry of Chinese fir in relation to stand and climate variables through Bayesian model averaging approach

Silva Fennica, 2021
Tree height-diameter allometry reflects the response of specific species to above and belowground resource allocation patterns. However, traditional methods (e.g.

Epiphytic bryophyte biomass estimation on tree trunks and upscaling in tropical montane cloud forests [PDF]

PeerJ, 2020
Epiphytic bryophytes (EB) are some of the most commonly found plant species in tropical montane cloud forests, and they play a disproportionate role in influencing the terrestrial hydrological and nutrient cycles. However, it is difficult to estimate the
