Выполнено сравнение отклика локальных популяций березы повислой (Betula pendula) на факторы среды по двум морфометрическим индексам: флуктуирующей асимметрии (ФА) и ксероморфизма (ИК) листьев. Показано, что изменения значений исследованных индексов практически не зависят от концентрации тяжелых металлов (ТМ) в тканях листа существенно обусловлены действием экзогенных факторов. Особенно сильна з...

We examined densities of endophytic fungi and their associations with performance of Eriocrania leaf-mining moth larvae on white birch (Betula pubescens) and silver birch (B. pendula) around a large copper±nickel smelter in SW Finland. The analysis is based on 2-year data collected from sites distributed along the pollution gradient from 0 to 10.8 km from the smelter. Endophyte densities were l...

Plant genetic variation and herbivores can both influence ecosystem functioning by affecting the quantity and quality of leaf litter. Few studies have, however, investigated the effects of herbivore load on litter decomposition at plant genotype level. We reduced insect herbivory using an insecticide on one half of field-grown Betula Pendula saplings of 17 genotypes, representing random intrapo...
