Effects of forest canopy structural complexity on productivity and its stability in the Qinling Mountains: Insights into environmental dependence

open access: yesTrees, Forests and People
Forest canopy structural complexity is a key determinant of forest productivity and exerts a strong influence on its stability. Yet, the relationship between forest canopy structural complexity and productivity and its stability under changing ...

Estimation of Forest Canopy Height and Aboveground Biomass from Spaceborne LiDAR and Landsat Imageries in Maryland

open access: yesRemote Sensing, 2018
Mapping the regional distribution of forest canopy height and aboveground biomass is worthwhile and necessary for estimating the carbon stocks on Earth and assessing the terrestrial carbon flux. In this study, we produced maps of forest canopy height and

Can increased training and awareness take forest research to new heights?

open access: yesTrees, Forests and People, 2020
Forest canopies contribute significantly to global forest biodiversity and ecosystem functioning, yet are declining and understudied. One reason for a knowledge gap is that accessing forest canopies can be difficult and dangerous.

Effect of leaf-on and leaf-off canopy conditions on forest height retrieval and modelling with ICESat-2 data

open access: yesInternational Journal of Digital Earth, 2023
Ice, Cloud, and land Elevation Satellite-2 (ICESat-2) provides effective photon-counting light detection and ranging (LiDAR) data for estimating forest height across extensive geographical areas.

SNOWMIP2: An evaluation of forest snow process simulation [PDF]

open access: yes, 2009
The Northern Hemisphere has large areas that are forested and seasonally snow covered. Compared with open areas, forest canopies strongly influence interactions between the atmosphere and snow on the ground by sheltering the snow from wind and solar ...

Light intensity affects spatial distribution of Heteroptera in deciduous forests

open access: yesEuropean Journal of Entomology, 2009
Studies on the effect of varying light intensity on the spatial distribution of flying insect communities are rare, particularly in complex ecosystems like forests.

Characterizing spatiotemporal variations of forest canopy gaps using aerial laser scanning data

open access: yesInternational Journal of Applied Earth Observations and Geoinformation, 2021
Spatiotemporal variations of forest canopy gaps are essential indicators for both forest dynamic monitoring by capturing their size and location variations and forest ecosystem management for tree seedling regeneration through altering the radiation ...

Abundant, distinct, and seasonally dynamic bee community in the canopy‐aerosphere interface above a temperate forest

open access: yes, 2022
Our understanding of how bees (Apoidea) use temperate forests is largely limited to sampling the understory and forest floor. Studies over the last decade have demonstrated that bee communities are vertically stratified within forests, yet the ecology of

Task‐Oriented Path Planning Towards Autonomous Sensor Network Deployment in Rainforest Canopies

open access: yesAdvanced Robotics Research, EarlyView.
An informative path planner for drone‐based deployment of wireless sensor networks in rainforest canopies is presented, addressing key challenges in large‐scale biodiversity monitoring. By integrating canopy surface detection with connectivity‐aware sampling under strict flight constraints, the approach enables efficient and reliable aerial sensor ...
