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 ...

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

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.

Phylogenomics, ecomorphological evolution, and historical biogeography in Deuterocohnia (Bromeliaceae: Pitcairnioideae)

American Journal of Botany, EarlyView.
Abstract Premise Species of Deuterocohnia (17 spp.) show extraordinary variation in elevation (0–3900 m a.s.l.) and growth forms, and many have narrow geographic distributions in the west‐central Andes and the Peru‐Chile coast. Previous research using few plastid and nuclear loci failed to produce well‐resolved or supported phylogenies.

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 ...

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 ...

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.

Experimental methods for wind tunnel studies of seed dispersal by wind

Applications in Plant Sciences, EarlyView.
Abstract The complexity and variability of natural environments make quantitative studies of seed wind dispersal challenging. Wind tunnel experiments offer a controlled alternative to investigate the mechanisms of seed wind dispersal. This review focuses on wind tunnels and the associated technologies used for studying seed wind dispersal, including ...

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 ...

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.
