Estimating coextinction risks from epidemic tree death [PDF]
, 2012 At least 10% of the world's tree species are threatened with extinction and pathogens are increasingly implicated in tree threats. Coextinction and threats to affiliates as a consequence of the loss or decline of their host trees is a poorly understood ...

Land Degradation &Development, EarlyView.ABSTRACT Permafrost is rapidly degrading in the sporadic zone, including palsa mires in Scandinavia. Peatlands in the area have likely accumulated heavy metals from atmospheric deposition of industrial contaminants in the wider region. As the palsa mire chemical composition is not well known, and in other permafrost regions the permafrost thaw may ...

Community dynamics of lignicolous lichens on standing deadwood in a 275‐year chronosequence
Oikos, EarlyView.Dead trees provide discrete habitat patches in which patch quality changes gradually due to wood decomposition. Although in most cases these patches persist for not more than a few decades, in some ecosystems deadwood decomposition and the consequent change in habitat patch quality can be a centuries‐long process, potentially leading to dynamics of ...

The Conjugates of Phenolic Acids in Lichens of the Order Lecanorales
International Journal of Secondary Metabolite, 2014 Lichens are symbiotic associations of a fungus (usually an ascomycete) and a photobiont, which may be an alga and/or a cyanobacterium. Lichens dominate on about 6–8% of land surface, mainly in the habitats with severe climatic conditions.

Lichens and lichenicolous fungi of the “Golczewskie Uroczysko” nature reserve (NW Poland)
Acta Biologica, 2017 Lichens of the “Golczewskie Uroczysko” nature reserve were studied in 2007–2008 and 2015–2016. Within the examined area, 68 species of lichens and 5 lichenicolous fungi were observed. Eleven species are included in the red list of threatened lichens in
