European beech is one of the most important deciduous tree species in natural forest ecosystems Central Europe. Its dominance now being questioned by emerging drought damages due to increased incidence severe summer droughts. In Switzerland, Fagus sylvatica have been observed Intercantonal Forest Observation Program since 1984. The dataset presented here includes 179176 annual observations tree...

Physicochemical properties and chemism of atmospheric precipitation, influenced by atmospheric air pollution, are a major element affecting contemporary degradation of the natural environment. It is known that water, apart from its function as a partner in physical reactions, is also the carrier of anthropogenic transformation of the natural environment. Acid rain is all the rain, snow, and mis...

Drought-induced cavitation resistance varies considerably between tree species and forest ecosystems (Maherali et al., 2004; Delzon et al., 2010) and is closely linked to survival under severe drought in both conifers (Brodribb & Cochard, 2009; Brodribb et al., 2010) and angiosperms (Kursar et al., 2009; Anderegg et al., 2012; Barigah et al., 2013; Urli et al., 2013). Choat et al. (2012) recent...

Attention is focused on the fact that in recent years there has been epiphytotic dieback out of many species forest woody plants both Ukraine and other countries world, which a dynamic character tendency to grow. In deep pathology this phenomenon, phytopathogenic bacteria, have high reproduction energy can penetrate plant from outside cause pathological process as vital obligates, were left wit...

New Zealand kauri (Agathis australis) trees are culturally, socially and ecologically significant within northern Zealand's nutrient-poor podocarp forest ecosystems. Phytophthora agathidicida is an aggressive oomycete pathogen, capable of killing A. australis across its ecological range, causing the disease known as dieback. The like many other species, commences a fine root rot which progresse...

Since 1991 epidemic dieback of the kelp Ecklonia radiata has been observed at the Leigh h4arine Reserve and other sites in northern New Zealand. As the dominant phaeophycean E. radiata is a very important component of the eastern coastal ecosystem, providing both food and refuge for many species. Examination of the E. radiata sap extracts by electron microscopy detected the presence of both str...

Background: A severe outbreak of Diplodia-associated dieback Pinus radiata D.Don shoots in 1967 prompted a pilot programme selection for resistance to dieback. Plus trees were selected 1970 absence dieback, growth and tree form, seed collected. Methods: Twenty open-pollinated progenies plus two control lots field-tested on sites, assessed around 6.5 years after planting. Alternative measures sh...

Seedling establishment is a critical part of the life cycle, thus seedling survival might be even more important for forest persistence under recent and future climate change. Scots pine forests have been disproportionally more affected by climate change triggered forest-dieback. Nevertheless, some Scots pine provenances might prove resilient to future drought events because of the species' lar...

Herbicides, particularly diuron, were correlated with severe and widespread dieback of the dominant mangrove, Avicennia marina (Forsk.) Vierh. var. eucalyptifolia (Val.) N.C. Duke (Avicenniaceae), its reduced canopy condition, and declines in seedling health within three neighbouring estuaries in the Mackay region of NE Australia. This unusual species-specific dieback, first observed in the ear...
