Evapotranspiration and water use efficiency in relation to climate and canopy nitrogen in U.S. forests [PDF]

, 2016
Understanding relations among forest carbon (C) uptake and water use is critical for predicting forest-climate interactions. Although the basic properties of tree-water relations have long been known, our understanding of broader-scale patterns is ...

Effect of stand density, canopy leaf area index and growth variables on Dendrocalamus brandisii (Munro) Kurz litter production at Simao District of Yunnan Province, southwestern China

Global Ecology and Conservation, 2020
Litterfall is the primary interface between the forest canopy and forest floor for efficient carbon and nutrient cycling. However, there is limited knowledge on factors that influence D. brandisii litter production and its seasonal dynamics.

Forest summer albedo is sensitive to species and thinning: how should we account for this in Earth system models? [PDF]

Biogeosciences, 2014
Although forest management is one of the instruments proposed to mitigate climate change, the relationship between forest management and canopy albedo has been ignored so far by climate models.

Using Microwave Profile Radar to Estimate Forest Canopy Leaf Area Index: Linking 3D Radiative Transfer Model and Forest Gap Model

Remote Sensing, 2021
Profile radar allows direct characterization of the vertical forest structure. Short-wavelength, such as Ku or X band, microwave data provide opportunities to detect the foliage.

Canopy structural modeling using object-oriented image classification and laser scanning [PDF]

, 2008
A terrestrial laser scanning (TLS) experiment was carried out in the EAGLE 2006 campaign to characterize and model the canopy structure of the Speulderbos forest. Semi-variogram analysis was used to describe spatial variability of the surface.

Estimates of Forest Canopy Height Using a Combination of ICESat-2/ATLAS Data and Stereo-Photogrammetry

Remote Sensing, 2020
Forest canopy height is an indispensable forest vertical structure parameter for understanding the carbon cycle and forest ecosystem services. A variety of studies based on spaceborne Lidar, such as ICESat, ICESat-2 and airborne Lidar, were conducted to ...

Forest Vegetation Texture Segmentation in Remote Sensing Image Based on Visual Attention [PDF]

Jisuanji gongcheng, 2018
As a typical texture unit of forest vegetation in remote sensing image,the canopy has prominent structural texture features,but the current segmentation methods make use of this texture insufficiently.Aiming at this problem,based on visual attention ...

Tropical Dry Forest Succession and the Contribution of Lianas to Wood Area Index (WAI) [PDF]

, 2009
The transmission and interception of light through the canopy is an important indicator of forest productivity in tropical forest ecosystems, and the amount of light that eventually reaches the forest floor is influenced by its interactions with leaves ...

Contribution of Lianas to Plant Area Index and Canopy Structure in A Panamanian Forest [PDF]

, 2016
Lianas are an important component of tropical forests, where they reduce tree growth, fecundity, and survival. Competition for light from lianas may be intense; however, the amount of light that lianas intercept is poorly understood.

Assessing the impact of canopy opening in regeneration status of tropical Terai forest of Nepal

Trees, Forests and People
Understanding how canopy structure influences regeneration is crucial for sustainable management of forests, particularly critical tropical forests. Although numerous studies have examined regeneration patterns, few have assessed how both seedling and ...
