Contrasting pathways of light and soil impacts on understory shrub diversity via functional traits in plantation and natural forests

Trees, Forests and People
The mechanisms by which environmental conditions in plantations and mixed natural forests drive changes in understory diversity through functional traits remain unclear, particularly regarding their dynamic effects during stand development.

A forest simulation approach using weighted Voronoi diagrams. An application to Mediterranean fir Abies pinsapo Boiss stands

Forest Systems, 2016
Aim of study: a) To present a new version of the forest simulator Vorest, an individual-based spatially explicit model that uses weighted Voronoi diagrams to simulate the natural dynamics of forest stands with closed canopies.

THE NATURAL REGENERATION IN OLD FOREST STANDS OF THE NATURE RESERVE "ROZTOCHYA"

Scientific Bulletin of UNFU, 2016
Досліджено лісовідновні процеси у 110-165-річних лісостанах різних типів лісу сугрудів і грудів Природного заповідника "Розточчя". Встановлено, що під наметом деревостанів переважає задовільне і добре (1,8-59,1 тис. шт./га) поновлення деревних порід із траплянням 80-100 %.

The Energy Cost of Sitting versus Standing Naturally in Man

Medicine & Science in Sports & Exercise, 2019
ABSTRACT Purpose Prolonged sitting is a major health concern, targeted via government policy and the proliferation of height-adjustable workstations and wearable technologies to encourage standing. Such interventions have the potential to influence energy balance and thus

Increased positive tree species mixture effects on the abundance and richness of Collembola with stand development in Canadian boreal forests

Forest Ecosystems
It is well established that species mixtures could enhance ecosystem functioning in diverse ecosystem types, with these benefits increasing over time. However, the impact of tree mixtures on Collembola communities following stand development in natural ...
