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.

Interpreting a Legacy Fossil Assemblage Excavated From Waribruk (New Guinea II Cave), GunaiKurnai Aboriginal Country, Snowy River National Park, Southeastern Australia

Archaeology in Oceania, EarlyView.
ABSTRACT In this paper we report on faunal remains recovered from a legacy archaeological excavation undertaken in the rockshelter entrance of Waribruk (New Guinea II Cave), a GunaiKurnai site located on the west bank of the Snowy River, East Gippsland, southeastern Australia.

Prospecting of Architectural Features Using LiDAR‐UAV Technology, Deep Neural Networks and Visualization Techniques: A Case Study in Kuélap and Cambolín (NW Peru)

Archaeological Prospection, EarlyView.
ABSTRACT High‐resolution and accurate synoptic images of terrestrial topography, even in densely forested areas, have proven valuable for archaeology by enabling the identification and characterization of relief patterns associated with ancient human activities. This study presents a novel approach that integrates digital terrain models (DTMs) obtained

Spatial metrics in fire ecology: seeking consistency amidst complexity

Biological Reviews, EarlyView.
ABSTRACT Technological advances, including remote sensing, have led to a proliferation of metrics used in ecological studies to examine spatial patterns of fire regimes and their ecological effects. Researchers can use many different metrics to analyse spatial variation in both fire events and resulting fire regimes, including fire size, shape ...

Extent, characteristics and policy applications of Key Biodiversity Areas

Biological Reviews, EarlyView.
ABSTRACT A global standard for the identification of Key Biodiversity Areas (KBAs) was published 10 years ago to provide a unified set of criteria for identifying ‘sites of significance for the global persistence of biodiversity’. We review the initiative's origins, the KBA identification process, characteristics of the current network, threats, policy

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 ...

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.

Life in the Forest Canopy

BioResources, 2013
Scientists have been devoting increased time and attention to the tops of trees. As made clear by results of their studies, the environment of the forest canopy is teeming with life. Perhaps because the crowns of trees are difficult for people to reach, and due to the micro-climates within them, they hold a rich and diverse collection of life forms ...
