The Conjugates of Phenolic Acids in Lichens of the Order Lecanorales
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.

Rainfall as a cause of mechanical damage to Pseudocyphellaria rufovirescens in a New Zealand temperate rainforest [PDF]
Lichens, like all poikilohydric plants, have a metabolism that is dependent on external moistening from their environment. In the case of green algal lichens high humidities may be sufficient for positive net photosynthesis to occur (Lange et al. 1993a).

Estimating coextinction risks from epidemic tree death [PDF]
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 ...

ABSTRACT We present the case of a 79‐year‐old female patient diagnosed with psoriasis who developed paradoxical drug reactions after administration of anti‐IL17 and anti‐IL‐23 inhibitors. Having shifted towards a rather eczematous phenotype, the patient received an anti‐IL‐4/IL‐3 inhibitor, subsequently developing erythroderma.
