Biomass estimation as a function of vertical forest structure and forest height. Potential and limiations for remote sensing (radar and LiDAR) [PDF]

open access: yes, 2011
Forest biomass stock, spatial distribution and dynamics are unknown parameters for many regions of the world. Today’s information is largely based on ground measurements on a plot basis without coverage in many remote regions that are fundamental for the

Effects of stand edges on the structure, functioning, and diversity of a temperate mountain forest landscape

open access: yesEcosphere, 2021
Human land use is fragmenting forests around the globe, increasing the edge density in forest landscapes. More frequent natural disturbances also increase the presence of edges in forest ecosystems.

Simulating realistic spatial structure for forest stands: a mimetic point process [PDF]

open access: yes, 2004
The recent development of individual based and spatially explicit models raises the question of how to simulate relevant initial states for these models, and more particularly how to simulate realistic spatial structures.

Coupling Avicennia tree architecture to radar backscatter models for estimating mangrove forest biomass [PDF]

open access: yes, 2004
The understanding of mangrove ecosystems functioning requires techniques allowing their forest structure and forest biomass to be assessed. Among them, radar measurements have demonstrated powerful capabilities that, however, must be validated ...

Forming Probably Stable Communities with Limited Interactions

open access: yes, 2018
A community needs to be partitioned into disjoint groups; each community member has an underlying preference over the groups that they would want to be a member of. We are interested in finding a stable community structure: one where no subset of members

Inferring alpha, beta, and gamma plant diversity across biomes with GEDI spaceborne lidar

open access: yesEnvironmental Research: Ecology, 2023
Biodiversity-structure relationships (BSRs), which describe the correlation between biodiversity and three-dimensional forest structure, have been used to map spatial patterns in biodiversity based on forest structural attributes derived from lidar ...

Height-diameter allometry of tropical forest trees [PDF]

open access: yes, 2011
Tropical tree height-diameter (H:D) relationships may vary by forest type and region making large-scale estimates of above-ground biomass subject to bias if they ignore these differences in stem allometry.

Forest Management Approaches for Coping with the Uncertainty of Climate Change: Trade-Offs in Service Provisioning and Adaptability

open access: yesEcology and Society, 2014
The issue of rapid change in environmental conditions under which ecosystem processes and human interventions will take place in the future is relatively new to forestry, whereas the provision of ecosystem services, e.g., timber or fresh water, is at the

Forest Stand Structure and Primary Production in relation to Ecosystem Development, Disturbance, and Canopy Composition [PDF]

open access: yes, 2016
Temperate forests are complex ecosystems that sequester carbon (C) in biomass. C storage is related to ecosystem-scale forest structure, changing over succession, disturbance, and with community composition.

Growth trends reveal the forest structure during Roman and Medieval times in Western Europe: a comparison between archaeological and actual oak ring series (Quercus robur and Quercus petraea) [PDF]

open access: yes, 2005
At some point in time, man has influenced nearly all forests in Western Europe. Most of the original forest cover has been converted to arable land and pastures, or has been cut for the supply of firewood and construction timber.
