Cellulose is the most abundant unique biopolymer in nature with widespread applications in bioenergy and high-value bioproducts. The large transmembrane-localized cellulose synthase (CESA) complexes (...
Convergence in water use efficiency within plant functional types across contrasting climates
water use efficiency plant functional types climates grassland permanent wetland savannah deciduous broadleaf and deciduous needleleaf forest
2023/11/28
Water use efficiency (WUE) provides a direct measure of the inextricable link between plant carbon uptake and water loss, and it can be used to study how ecosystem function varies with climate. We ana...

Foresters frequently lack sufficient information about thinning intensity effects to optimize semi-natural forest management and their effects and interaction with climate are still poorly understood....
Foliage and fine roots in terms of growth efficiency – a comparison between European beech and Norway spruce at early growth stages
allometric equations fine root morphology leaf area stem diameter stem mass production interspecies differences
2015/4/24
The quantification of stems (under- and overbark), foliage and fine roots in 14-year-old stands of European beech and Norway spruce grown on the same site were evaluated. Therefore, 60 trees of each s...
