Comparison of partial least squares-discriminant analysis, support vector machines and deep neural networks for spectrometric classification of seed vigour in a broad range of tree species
least squares-discriminant analysis spectrometric classification seed tree species
2023/6/5
Seed vigour significantly influences the seed production and plant regeneration performance. The capability of NIR spectroscopy to identify seed vigour across multiple tree species rapidly and cost-ef...

Snow depth as a function of canopy cover and other site attributes in a forested ungulate winter range in southeast British Columbia
canopy cover southeast British Columbia snow depth ungulate winter range
2009/1/9
Snow depth is considered a major influence on deer (Odocoileus spp.) winter distribution and abundance in northern parts of their range. Overstorey canopy cover is often considered a principal variabl...
