Airborne multispectral scanner (MSS) digital data (3.8 m resolution) and MEIS II digital data (10 ;m resolution) have been used to investigate the effects of anomalous metal concentrations in the soil on the spectral reflectance of selected tree species. Analysis of on-site spectral measurements...
analysis and machine learning classification procedures, after field calibration and photogrammetric processing of consumer-grade unmanned aerial vehicle (UAV) digital camera data, were implemented to classify tree species in a conifer forestin the Great Lakes/St Lawrence Lowlands Ecoregion, Ontario, ...
However, a considerable gap in ethnopharmacological data was found for species of skullcaps (, and . ) and St. John's wort (, , ) growing in northern Ontario. These findings provide promising incentives in the ethnopharmacological community for medicinal research in this region. 展开 ...

We lacked distribution data for amphibians and vascular plants from Ontario, located south-east of Quebec, where some future immigrants to Quebec potentially occur. For vascular plants other than trees, we modeled only species already present in the province of Quebec. These sampling constraints ...

Our study is the first unravelling the habitat use and selection of this poorly studied species in a semi-natural lowland area of northern Italy. The multi-scale analysis of habitat selection was carried out with regards to the tree species composition and vegetation structure, which are regarded...
