Sugar Maple Litter Decay Rates Are Reduced More Strongly by Drought Than by American Beech Proliferation in the Understory [PDF]

open access: yesEcology and Evolution
Recurrent drought threatens high‐latitude deciduous forests in eastern North America. The decline of sugar maple (Acer saccharum) at its northern limits under additional stress imposed by changing climate regimes and its replacement by American beech ...

Control of rhododendron (Rhododendron ponticum and R. flavum) in the eastern beech (Fagus orientalis) forests of Turkey

open access: yesNew Forests, 2004
Because purple-flowered rhododendron (Rhododendron ponticum L.) and yellow-flowered rhododendron (R. flavum Don.) significantly reduce seedling growth and regeneration of eastern beech (Fagus orientalis Lipsky) as well as local floristic diversity in northern Turkey, effective and cost-efficient woody control is needed.
