Forest Net Primary Production Resistance Across a Gradient of Moderate Disturbance [PDF]

open access: yes, 2014
The global carbon (C) balance is vulnerable to disturbances that alter terrestrial C uptake and loss. Moderate disturbances that kill or defoliate only a subset of canopy trees such as insect defoliation, drought, and age-related senescence are ...

Stand-level drivers of tree-species diversification in Mediterranean pine forests after abandonment of traditional practices [PDF]

open access: yes, 2015
The progressive abandonment of traditional forest management over the last few decades has led to significant densification processes in most Mediterranean pine stands.

Gainesville's Urban Forest Canopy Cover

open access: yesEDIS, 2009
FOR-215, a 3-page illustrated fact sheet by Francisco Escobedo, Jennifer A. Seitz, and Wayne Zipperer, examines how tree cover changes over time, how tree composition and location influence urban forest canopy and leaf area, and how tree and ground surface covers vary across Gainesville. Includes references.

Comparison of four different programs for the analysis of hemispherical photographs using parameters of canopy structure and solar radiation transmittance [PDF]

open access: yes, 2013
There have been many studies involving the use of hemispherical photographs to indirectly estimate canopy structures and forest light environments.

Deep learning-driven forest canopy height mapping in boreal regions through multi-source remote sensing fusion: Integrating Sentinel-1/2, PALSAR, and ICESat-2/LVIS data

open access: yesInternational Journal of Applied Earth Observations and Geoinformation
Forest canopy height is a key indicator for estimating forest carbon sinks and managing vegetation growth. Existing methods for fusing optical and Light Detection and Ranging (LiDAR) data still have limitations in canopy height estimation for boreal ...

Effects of Silvopasture Establishment on Aqueous and Gaseous Soil N Losses at the University of New Hampshire Organic Dairy Research Farm [PDF]

open access: yes, 2017
The expansion of local agriculture in the New England region is putting increased pressure on farmers to expand their arable land base. While clear-cutting is a traditional method of converting forested land to agriculture, it is known for having ...

Geometric-optical Modeling of a Conifer Forest Canopy [PDF]

open access: yes
The objective of this research is to explore how the geometry of trees in forest stands influences the reflectance of the forest as imaged from space. Most plant canopy modeling has viewed the canopy as an assemblage of plane-parallel layers on top of a ...

Composition and Host-Use Patterns of a Scarab Beetle (Coleoptera: Scarabaeidae) Community Inhabiting the Canopy of a Lowland Tropical Rainforest in Southern Venezuela [PDF]

open access: yes, 2019
The adult scarab beetle fauna of the canopy in a lowland tropical rainforest in southern Venezuela was observed and collected by means of a 42 m-tall tower crane for a complete year.

DIRECT ESTIMATION OF ABOVEGROUND FOREST PRODUCTIVITY THROUGH HYPERSPECTRAL REMOTE SENSING OF CANOPY NITROGEN [PDF]

open access: yes, 2002
The concentration of nitrogen in foliage has been related to rates of net photosynthesis across a wide range of plant species and functional groups and thus represents a simple and biologically meaningful link between terrestrial cycles of carbon and ...

Hydrological Responses to Rainfall Across Varying Canopy Densities in a Tropical Peat Swamp Forest

open access: yesJurnal Manajemen Hutan Tropika
Peat swamp forests play a vital role in carbon storage, water regulation, and biodiversity conservation. This study about the hydrological behaviour of three compartments in the Resak Tambahan Forest Reserve with different forest canopy densities ...
