Optimizing the Remote Detection of Tropical Rainforest Structure with Airborne Lidar: Leaf Area Profile Sensitivity to Pulse Density and Spatial Sampling

open access: yesRemote Sensing, 2019
Airborne Laser Scanning (ALS) has been considered as a primary source to model the structure and function of a forest canopy through the indicators leaf area index (LAI) and vertical canopy profiles of leaf area density (LAD).

Light Relations in Plant Canopies

open access: yesApplied Optics, 1970
A theory of light relations in plant canopies is presented which has potential applications in remote sensing and photosynthetic modeling of plant canopies. Predictions of the model are compared with field measurements of light reflection and transmission in a corn crop.

Dynamics of biotic resistance to plant invasions

open access: yesBiological Reviews, EarlyView.
ABSTRACT Biotic resistance, the reduction in invasion success caused by native communities, plays an important role in the long‐term dynamics of biological invasions. A large body of empirical research on biotic resistance has accumulated since the last comprehensive review on the subject 20 years ago, enabling us to achieve a refined understanding of ...

What drives animal responses to high severity fire? The role of functional traits

open access: yesBiological Reviews, EarlyView.
ABSTRACT Fire regimes are changing worldwide, with increases in the frequency, extent, and severity of fires posing growing risks to biodiversity. Fire severity – the degree of habitat alteration following fire – strongly influences both immediate survival and long‐term recovery of fauna.

Royal canopy over the church entrance: Forms, spatial contexts, iconographic programs, and meaning of the dome in Serbian narthexes of the 14th century [PDF]

open access: yesZbornik Radova Filozofskog Fakulteta u Prištini
The churches commissioned by King (later Emperor) Stephen Dušan, his important dignitaries, and later Serbian rulers-e.g., Holy Archangels near Prizren, Lesnovo, Hilandar, Markov Manastir, Ravanica, and Manasija-often have a narthex or an entrance porch ...

Land birds on atolls: diversity, origin, and function

open access: yesBiological Reviews, EarlyView.
ABSTRACT Oceanic islands are global hotspots of avian biodiversity and endemism. Their isolation and distinct environmental conditions have uniquely shaped the evolutionary trajectories of island birds, while, in turn, land bird communities have become critical providers of ecological functions to island ecosystems.

Canopy structural modeling using object-oriented image classification and laser scanning [PDF]

open access: yes, 2008
A terrestrial laser scanning (TLS) experiment was carried out in the EAGLE 2006 campaign to characterize and model the canopy structure of the Speulderbos forest. Semi-variogram analysis was used to describe spatial variability of the surface.

Les lits de Louis XIII à Versailles. Entre sobriété et majesté : manifeste d’un dessein royal

open access: yesIn Situ, 2019
Louis XIII’s beds at Versailles are not the best-known ones in the history of the palace. No pictures of them survive but other archival and printed sources allow us to analyse them and to study their usages and symbolic values.
