Modeling 3D Canopy Structure and Transmitted PAR Using Terrestrial LiDAR

Canadian Journal of Remote Sensing, 2017
The heterogeneity and 3-dimensional (3D) organization of forest canopy elements is highly linked with the spatial variability of within and below canopy light. Using terrestrial LiDAR we studied the influence of several parameters in efficiently building

Application of a Three-Dimensional Radiative Transfer Model to Retrieve the Species Composition of a Mixed Forest Stand from Canopy Reflected Radiation

Remote Sensing, 2018
The paper introduces a three-dimensional model to derive the spatial patterns of photosynthetically active radiation (PAR) reflected and absorbed by a non-uniform forest canopy with a multi-species structure, as well as a model algorithm application to ...

Landscape-scale changes in forest canopy structure across a partially logged tropical peat swamp [PDF]

Biogeosciences, 2015
Forest canopy structure is strongly influenced by environmental factors and disturbance, and in turn influences key ecosystem processes including productivity, evapotranspiration and habitat availability.

Divergent responses of forest canopy height to environmental conditions across China

Ecological Indicators
As major components of terrestrial ecosystems, forest ecosystems play an important role in sequestering carbon and hence mitigating climate change. Canopy height is a crucial factor characterizing the structure and function of forest ecosystems, yet the ...

Coming down from the trees: is terrestrial activity in Bornean orangutans natural or disturbance driven? [PDF]

, 2014
The orangutan is the world's largest arboreal mammal, and images of the red ape moving through the tropical forest canopy symbolise its typical arboreal behaviour. Records of terrestrial behaviour are scarce and often associated with habitat disturbance.

Light-related variation in sapling architecture of three shade-tolerant tree species of the Mexican rain forest [PDF]

, 2008
The crown architecture of three shade-tolerant tree species (two subcanopy and one mid-canopy) was analyzed in relation to the light regime of the forest understorey.

Canopy soil bacterial communities altered by severing host tree limbs [PDF]

PeerJ, 2017
Trees of temperate rainforests host a large biomass of epiphytic plants, which are associated with soils formed in the forest canopy. Falling of epiphytic material results in the transfer of carbon and nutrients from the canopy to the forest floor.

Quantifying Dynamics in Tropical Peat Swamp Forest Biomass with Multi- Temporal LiDAR Datasets [PDF]

, 2013
Tropical peat swamp forests in Indonesia store huge amounts of carbon and are responsible for enormous carbon emissions every year due to forest degradation and deforestation.

Key canopy traits drive forest productivity [PDF]

Proceedings of the Royal Society B: Biological Sciences, 2012
Quantifying the mechanistic links between carbon fluxes and forest canopy attributes will advance understanding of leaf-to-ecosystem scaling and its potential application to assessing terrestrial ecosystem metabolism. Important advances have been made, but prior studies that related carbon fluxes to multiple canopy traits are scarce. Herein, presenting

Reliability of canopy photography for forest ecology and biodiversity studies

Ecological Indicators
Understory is a key component of forest biodiversity. The structure of the forest stand and the horizontal composition of the canopy play a major role on the light regime of the understory, which in turn affects the abundance and the diversity of the ...
