Increasing global background concentrations of tropospheric ozone (O(3)) are expected to affect both crops and forest ecosystems negatively. The phytotoxic effects of O(3) are mainly associated with the O(3)-induced production of reactive oxygen species (ROS) in excess of the ability of the plant to maintain ROS below the tolerance threshold. It is the balance between O(3) uptake and cellular a...

This study aimed to determine the effects of root pruning on the physicochemical characteristics and microbial activities of poplar rhizosphere soil. The root systems of 5-year-old poplar (Populus×euramericana cv. 'Neva') trees were manually pruned at 6, 8, or 10 times diameter at breast height (DBH) from the trunk (severe, moderate, and light, respectively) along both inter-row sides. Moderate...

Abstract The biodiversity of natural or semi-natural native, old oak woodlands have high conservation importance, especially in landscapes monocultural forest plantations and arable fields. With a wider variety microhabitats foraging sources, such forests can provide essential habitat for native bird communities. We conducted study using point counts to compare the communities pedunculate ( Que...
