Classification of tree species and standing dead trees in Boreal forests using UAV‐based RGB, multispectral, and LiDAR point clouds

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
We evaluated single‐ and multi‐sensor UAV approaches for classifying tree species and standing dead trees in boreal forests, focusing on key biodiversity indicators such as European aspen. Using spectral and structural features extracted from RGB, multispectral (MSP), and LiDAR point clouds for 1,205 field‐measured trees, we compared classification ...

Mapping Scytonemin Pigment Content and Biocrust Functional Indicators Using High‐Resolution Multispectral Imagery

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
We demonstrate that high‐resolution multispectral imagery combined with machine learning can accurately predict key biocrust functional indicators, particularly the UV‐protective pigment scytonemin, across dryland ecosystems. Using fine‐scale imagery acquired in the Chihuahuan Desert and Colorado Plateau, we identified spectral bands strongly ...

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

open access: yesRemote 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.

Rilievi in sella a un quad

open access: yesGEOmedia, 2013
Renewable energy—including biomass, geo- thermal, hydroelectric, wind and solar—is big business in Italy. Solar farms able to produce 1 MW or more of nominal power are considered “large.” Before installing such a PV plant, an acc urate topographical ...

A low‐cost, portable polarizing digital light microscope for monitoring crystal growth and for crystal harvesting

open access: yesJournal of Applied Crystallography, EarlyView.
A low‐cost, portable, medium‐resolution polarizing digital light microscope device for monitoring crystal growth and for crystal harvesting is described. The device can be used with a cell phone or a personal computer for real‐time imaging by professional and amateur scientists alike.Motivated by the need for a convenient way to demonstrate the growth ...

Marine rewilding principles as a guiding framework for large‐scale ecosystem restoration

open access: yesConservation Science and Practice, EarlyView.
As marine ecosystems face accelerating degradation from human pressures, interest is growing in approaches that move beyond protection toward active recovery of ecological processes. This article introduces marine rewilding as a forward‐looking framework and synthesizes ecological and social science to develop eight transdisciplinary principles that ...

Behavioural Treatments for Tourette Syndrome: An Evidence-Based Review

open access: yesBehavioural Neurology, 2013
Tourette syndrome (TS) is a disorder characterised by multiple motor and vocal tics and is frequently associated with behavioural problems. Tics are known to be affected by internal factors such as inner tension and external factors such as the ...

Pharmacological treatment of tics in Gilles de la Tourette Syndrome

open access: yesClinical Management Issues, 2011
Tourette syndrome is a neurodevelopmental disorder characterised by the chronic presence of multiple motor tics (e.g. eye blinking, shoulder shrugging, etc.) and at least one vocal/phonic tic (e.g. grunting or sniffing).
