The characteristics of Glycyrrhiza plants from 12 collection sites in southeastern Kazakhstan were investigated. G. uralensis was observed at 9 of the sites from Almaty to Shu, and G. glabra was observed at 8 sites. At 4 sites near Shu, and 1 site near Almaty, G. glabra and G. uralensis grew together forming a mixed population, and intermediate-type plants between them were also observed at 3 s...

Formaldehyde-based adhesives are used in the forestry industry. This is because formaldehyde inexpensive, easy to use and resistant moisture; it also has particular mechanical effects. Formaldehyde both advantages disadvantages. It known that various diseases such as lung cancer occur humans a result of release into air during after board production. In this study, urea glue mixture was prepare...

Largely consistent with general predictions and earlier empirical studies, it appears that post-Little Ice Age climate warming has started to affect large-scale biogeographic patterns in northern Sweden. Long-term monitoring subalpine adjacent regions reveals sparse spread of broadleaved thermophilic tree species. Saplings Quercus robur, Ulmus glabra, Acer platanoides, Alnus glutinosa Betula pe...

Abstract Invasive fungal pathogens are an increasing problem globally and can cause strong effects on forest ecosystems. In this study, we contrast vegetation surveys in eutrophic elm ( Ulmus glabra ) ash Fraxinus excelsior forests southern Sweden, conducted just prior to the arrival of Dutch disease (DED) 1989, then again 2021, several years after dieback (ADB) began. At sample plot scale, spe...
