Using Airborne Laser Scanning and Sentinel‐2 to Understand Subcanopy Light Regimes and Understory Diversity of Vascular Plants in Temperate Mountain Forests

Remote Sensing in Ecology and Conservation, EarlyView.
This study demonstrates that not just Airborne Laser Scanning, but also Sentinel‐2 can effectively estimate absolute canopy cover and canopy cover heterogeneity ‐ structural metrics that determine the subcanopy light regime, found to be linked to the vascular plant species richness in the understory of temperate mountain forests.

MULTI-WAVELENGTH AIRBORNE LASER SCANNING FOR ARCHAEOLOGICAL PROSPECTION [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2013
Airborne laser scanning (ALS) is a widely used technique for the sampling of the earth's surface. Next to the widely used geometric information current systems provide additional information about the signal strength of each echo.

Survey on differential estimators for 3d point clouds

Computer Graphics Forum, EarlyView.
Abstract Recent advancements in 3D scanning technologies, including LiDAR and photogrammetry, have enabled the precise digital replication of real‐world objects. These methods are widely used in fields such as GIS, robotics, and cultural heritage. However, the point clouds generated by such scans are often noisy and unstructured, posing challenges for ...

Integrating fossil data in ecological niche models to improve predictions of future habitat of Caribbean corals

Conservation Biology, EarlyView.
Abstract Ecological niche models (ENMs) are used to assess the abiotic preferences of species by linking their occurrences to the environmental conditions in which they live. We developed a fossil‐informed ENM framework that integrates mid‐Holocene and modern occurrences to test niche stability and reconstruct abiotic niche characteristics for four ...

Testing coir (coconut) fiber as a novel, biodegradable material for coral reef restoration: coir interactions with larval and juvenile corals

Restoration Ecology, EarlyView.
Abstract Introduction Coral populations have declined in recent decades, largely due to anthropogenic climate change. In response, coral restoration projects are being implemented, and rubble stabilization is one such approach. Rubble beds form when dead coral fragments accumulate on the seafloor and can be mobilized by water flow.

Antifouling capacity of substrate materials and their effects on settlement and post‐settlement survival of Acropora palmata and Orbicella faveolata

Restoration Ecology, EarlyView.
Abstract Introduction In coral reef restoration, sexual reproduction is a key methodology to enhance coral population recovery. However, post‐settlement survival remains a major bottleneck, as spat are particularly vulnerable to competition with fouling organisms.

Riegl, Hegel, Kunstwollen, and the Weltgeist [PDF]

RACAR : Revue d'art canadienne, 2020
Le but de cet article et d’offrir une réévaluation du concept de Kunstwollen proposé par Aloïs Riegl et d’établir sa relation avec la philosophie de Hegel. Cette réévaluation est centrée sur une discussion d’un certain nombres d’idées difficiles à résoudre au sujet du développement dialectique et de la nécessité qui sous-tendent les analyses ...
