Within‐tree spatial heterogeneity of sap flow velocities and wood properties and its effect on the uncertainty of tree level sap flux estimates

PLANTS, PEOPLE, PLANET, EarlyView.
As forests are important for biodiversity and recreation and provide vital resources globally, it is essential that their health can be accurately monitored, for example, by using sap flow probes to measure tree water uptake. We investigated whether sap flow measurements might differ at various locations within the same tree due to variation in wood ...

Recruitment dynamics in conifer-dominated uneven-aged forests in the carpathians

Forest Ecosystems
In permanently uneven-aged forests, continuous ingrowth of recruitment into higher stand layers is a critical process for the formation and maintenance of differentiated stand structures.

Cisovka - the relic population of Abies alba and its relationship to man-made silver-fir stands in Białowieża primeval forest

Acta Societatis Botanicorum Poloniae, 2014
In Białowieża Primeval Forest, in 1823 Stanisław Górski discovered on the Cisovka Hag, a relic population of European silver-fir (Abies alba Mill.). This population is isolated and most away, 120 km to the North-East, from the border of European-silver ...

Chemical Composition and Activity of Essential Oils of Albanian Coniferous Plants on Plant Pests

Chemistry Proceedings, 2022
The present study was conducted to evaluate and compare the chemical composition and bioactivity of essential oils on different insect organisms from four Albanian coniferous plants. The phytochemical analysis carried out using GC-MS showed that the oils

Using Airborne Laser Scanning and Sentinel‐2 to Understand Subcanopy Light Regimes and Understory Diversity of Vascular Plants in Temperate Mountain Forests

Remote Sensing in Ecology and Conservation, EarlyView.
This study demonstrates that not just Airborne Laser Scanning, but also Sentinel‐2 can effectively estimate absolute canopy cover and canopy cover heterogeneity ‐ structural metrics that determine the subcanopy light regime, found to be linked to the vascular plant species richness in the understory of temperate mountain forests.

Effects of silver fir (Abies alba Mill.) on the humus forms in Norway spruce (Picea abies (L.) H. Karst.) stands

Journal of Forest Science, 2018
The effects of silver fir (Abies alba Miller) on the soil compared to Norway spruce (Picea abies (Linnaeus) H. Karsten) were evaluated. Altitude of the study site is 790 m a.s.l., mild slope of 10° facing SW, forest site is spruce-beech on acid soil. The
