Abstract The recent increase in the frequency and severity of drought‐induced tree mortality events in low‐elevation, mesic European forests poses considerable challenges to forest management and requires an understanding of its causes. Here, we propose a novel, parsimonious framework for integrating the factors underlying drought‐induced tree ...

Spectral response of chlorophyll content during leaf senescence in European beech trees [PDF]
Leaf chlorophyll content declines in response to environmental stressors and during natural senescence periods. Assessments of forest health and vulnerability to stressors require repeated measurements of forest health to quantify declines in chlorophyll

Site condition effects on beech leaf disease symptom severity in southwestern Ontario hardwood forests [PDF]
The health of American beech (Fagus grandifolia Ehrh.) is threatened in North America due to its susceptibility to various pathogens, including beech leaf disease.

The phenotypic expression of QTLs for partial resistance to barley leaf rust during plant development [PDF]
Partial resistance is generally considered to be a durable form of resistance. In barley, Rphq2, Rphq3 and Rphq4 have been identified as consistent quantitative trait loci (QTLs) for partial resistance to the barley leaf rust pathogen Puccinia hordei ...

Crown plasticity and neighborhood interactions of European beech (Fagus sylvatica L.) in an old-growth forest [PDF]
Competition for canopy space is a process of major importance in forest dynamics. Although virgin and old-growth European beech (Fagus sylvatica L.) forests in Europe have been studied for many years, there are to date no studies of individual-tree crown

A foliar disease model for use in wheat disease management decision support systems. [PDF]
A model of winter wheat foliar disease is described, parameterised and tested for Septoria tritici (leaf blotch), Puccinia striiformis (yellow rust), Erysiphe graminis (powdery mildew) and Puccinia triticina (brown rust).

The study of vegetation community and structural change has been central to ecology for over a century, yet the ways in which disturbances reshape the physical structure of forest canopies remain relatively unknown.

This study identified a specific sequence of an extended drought followed by exceptional rainfall as a necessary precursor for mouse plagues in southeastern Australia. Long‐term rainfall anomalies interact with ecological processes to reset population dynamics, creating conditions that support rapid mouse population growth following periods of ...

Variation in performance of beech saplings of 7 European provenances under shade and full light conditions [PDF]
The use of beech seedlings from South-East European and North-West (NW) provenances for underplanting in coniferous forests in North-West Europe was investigated by means of experimental shading.

N‐labeled beech and ash leaf litter
The aim of this study was to determine the influence of leaf-litter type (i.e., European beechFagus sylvatica L. and European ashFraxinus excelsior L.) and leaf-litter mixture on the partitioning of leaf-litter C and N between the O horizon, the topsoil,
