Ecological functions of forest stands in urbanized environment of Moscow

RUDN Journal of Agronomy and Animal Industries, 2019
In urban forests, stock production is not the main function of stands. Carbon sequestration, the release of oxygen and phytoncides, dust precipitation, and changing wind conditions et al. are the main environmental functions.

Structural heterogeneity modulates the effects of stem density on standing biomass in mature dry Isoberlinia woodlands

Frontiers in Forests and Global Change
IntroductionWhile the impacts of forest structural attributes on above-ground biomass (AGB) has been largely documented in closed-canopy forests, much less is known in dry forests, where water rather than light drives biomass accumulation. In particular,

Analysis of monoterpene variation in natural stands and plustrees of Pinus sylvestris in Finland.

Silva Fennica, 1986
Variation of monoterpene composition of L. was studied in Southern, Central and Northern Finland using data from both natural stands and plus trees. The natural stands were analysed using different techniques and for fewer terpenes than the plus trees ...

Lower alpha, higher beta, and similar gamma diversity of saproxylic beetles in unmanaged compared to managed Norway spruce stands.

PLoS ONE, 2022
Strong anthropogenic pressures on global forests necessitate that managed forests be evaluated as habitat for biodiversity. The complex pattern of habitat types created in forestry systems is ideal for analyses through the theoretical framework of alpha (
