Seasonal Patterns in Spectral Irradiance and Leaf UV-A Absorbance Under Forest Canopies

Frontiers in Plant Science, 2020
Plants commonly respond to UV radiation through the accumulation of flavonoids and related phenolic compounds which potentially ameliorate UV-damage to crucial internal structures.

Community Structure in an Isolated Tropical Forest Biome: One Year of Fruit-Feeding Butterfly Trapping in Four Habitats in the Western Ghats, India

Diversity, 2022
Insect communities in tropical forests tend to be structured vertically and with respect to tree fall gaps and edges. Furthermore, insect communities vary over time.

An integrated model of soil-canopy spectral radiances, photosynthesis, fluorescence, temperature and energy balance [PDF]

, 2009
This paper presents the model SCOPE (Soil Canopy Observation, Photochemistry and Energy fluxes), which is a vertical (1-D) integrated radiative transfer and energy balance model. The model links visible to thermal infrared radiance spectra (0.4 to 50 μm)

The regional market for non-timber forest products

Desenvolvimento e Meio Ambiente, 2018
The fate of tropical forests is shaped by their perceived value, which in turn depends on awareness of their benefits.  Regional markets for non-timber forest products (NTFPs) could both help rural people generate income from forests and raise urban ...

Large-scale variation in combined impacts of canopy loss and disturbance on community structure and ecosystem functioning. [PDF]

, 2013
Ecosystems are under pressure from multiple human disturbances whose impact may vary depending on environmental context. We experimentally evaluated variation in the separate and combined effects of the loss of a key functional group (canopy algae ...

The dependence of canopy layer turbulence on within-canopy thermal stratification [PDF]

Agricultural and Forest Meteorology, 1992
Transport properties near the Earth's surface are strongly influenced by the thermal stratification of the atmosphere. Until now, no distinction has been made between thermal stability parameters within and above a plant canopy, and it has been usual to classify canopy transport processes in terms of above-canopy stability parameters only. The question

Relighting Photographs of Tree Canopies [PDF]

IEEE Transactions on Visualization and Computer Graphics, 2011
We present an image-based approach to relighting photographs of tree canopies. Our goal is to minimize capture overhead; thus the only input required is a set of photographs of the tree taken at a single time of day, while allowing relighting at any other time. We first analyze lighting in a tree canopy both theoretically and using simulations.
