The Canadian Entomologist 32: 965 981 (2000) Leaf and bark volatiles from non-host birches, Betula pendula Roth. and Betula pubescens Ehrh. (Betulaceae), and aspen, Populus tremula L. (Salicaceae), were tested on spring-dispersing Tomicus piniperda (L.) and Tomicus minor (Hart.) by gas chromatographic electroantennographic detection (GC-EAD) and by attractantbaited traps in southern Sweden. GC-...

Investing in planting genetically improved silver birch ( Roth) Swedish plantations requires understanding how stands will develop over their entire rotation. Previous studies have indicated relatively low production of compared to Norway spruce (L.) Karst.) and Scots pine L.). This could result from using unrepresentative basic data, collected unimproved, naturally-regenerated spp.) grow...

Abstract Rainfall interception process is an important part of the biohydrological cycle, in which vegetation plays role by regulating amount and dynamics rainfall reaching ground. In this paper, event-based analysis performed to discuss influence on dynamic temporal response soil volumetric water content (VWC) upper layer during events. More specifically, six events that occurred between 19 No...

Over the coming decades, climate change can decrease forest productivity and stability in many semiarid regions. Tree-ring width (TRW) analysis allows estimation of tree sensitivity to droughts, including resistance (Rt) resilience (Rc) indexes. It helps find adaptive potential individual trees populations. On a stand scale, it is affected by habitat conditions species’ ecophysiological charact...

Air humidity indicated as vapour pressure deficit (VPD) is directly related to transpiration and stomatal function of plants. We studied the effects of VPD and nitrogen (N) supply on leaf metabolites, plant growth, and mineral nutrition with young micropropagated silver birches (Betula pendula Roth.) in a growth chamber experiment. Plants that were grown under low VPD for 26 d had higher biomas...
