(MDPI AG (Multidisciplinary Digital Publishing Institute-MDPI), 2021)
The Atiwa forest reserve of Ghana sits upon roughly 150 million tons of bauxite. The Government has decided to mine and use the proceeds for national infrastructure development programs. This article examines the impact ...
Overwinter Storage of European Beech and Norway Spruce Planting Stock: Effect of Different Methods and Temperature Conditions
(MDPI AG (Multidisciplinary Digital Publishing Institute-MDPI), 2021)
The aim of this research was to compare methods of overwinter storage of forest tree species planting stock and to specify of the optimal and the minimal temperature for freezing. Planting stock of European beech and Norway ...
Efficiency of Harvester with the Debarking Head at Logging in Spruce Stands Affected by Bark Beetle Outbreak
(MDPI AG (Multidisciplinary Digital Publishing Institute-MDPI), 2021)
This paper deals with the use of debarking modifications of the conventional harvester head in the conditions of felling due to bark beetle calamity. For this purpose, a time study was established, in which the conventional ...
Multi-seasonal systematic camera-trapping reveals fluctuating densities and high turnover rates of Carpathian lynx on the western edge of its native range
(Nature Publishing Group, 2021)
Camera-trapping and capture-recapture models are the most widely used tools for estimating densities of wild felids that have unique coat patterns, such as Eurasian lynx. However, studies dealing with this species are ...
Stand factors affecting the wood density of naturally regenerated young silver birch growing at the lower altitude of the Czech Republic region
(Výskumný ústav papiera a celulózy, Sekcia Slovenský drevársky výskumný ústav, 2019)
The objective of this study was to investigate the basic wood density (rho(k) ) of the silver birch (Betula pendula Roth.) trees in relation to the stand structure. This research was conducted in three stands of different ...
Xylogenesis and phloemogenesis of Norway spruce in different ages stands at middle altitudinal zone
(Výskumný ústav papiera a celulózy, Sekcia Slovenský drevársky výskumný ústav, 2020)
This study aimed to determine the influence of the stand age and selected weather conditions on the cambial activity, xylem and phloem formation and their development. For the analysis, microcores were taken weekly from ...
Seed Viability and Potential Germination Rate of Nine Endemic Boswellia Taxa (Burseraceae) from Socotra Island (Yemen)
(MDPI AG (Multidisciplinary Digital Publishing Institute-MDPI), 2022)
The endemic Boswellia species (Burseraceae) on Socotra Island (Yemen) are of great local significance due to their various local ethnobotanical uses. However, despite the fact that these trees are endangered, little is ...
Auxin (IAA) and soluble carbohydrate seasonal dynamics monitored during xylogenesis and phloemogenesis in Scots pine
(Italian Society of Silviculture and Forest Ecology, 2018)
The metabolic activity of phytohormones and the accumulation of carbohydrates affect the reactivation of the cambial zone and the radial increment of woody plants. We aimed to monitor the dynamics of indole-3-acetic acid ...
