[EN] Parmotrema pseudotinctorum (des Abb.) Hale is a foliose lichen able to colonize
large areas on rock surfaces in semiarid and warm localities in the Canary Islands. In
this contribution, we investigate the phycobionts ...
[EN] The precise boundary delineations between taxa in symbiotic associations are very important for evolutionary and ecophysiological studies. Growing evidence indicates that in many cases, the use of either morphological ...

Lichen thalli are permeable to airborne substances, including heavy metals, which are harmful to cell metabolism. Ramalina farinacea shows a moderate tolerance to Pb. This lichen comprises two Trebouxia phycobionts, ...
[EN] The anatomical changes produced by ozone in leaves of the Mediterranean deciduous shrub Pistacia
terebinthus (terebinth) were investigated in an OTC experiment. Plants were exposed at three different
O3 levels from ...
Fast urbanization has led to ozone (O3) being the main pollutant in summer in most of China. To assess future ground-level O3 effects on the service of urban greening species and clarify the underlying mechanism of O3 ...
[EN] An open-top chamber study was conducted to investigate the tissue and cellular-level foliar effects of ozone (O-3) on a Mediterranean evergreen species, the mastic plant (Pistacia lentiscus L.). Plants were exposed ...

[EN] Background
Reactive oxygen species (ROS) are normally produced in respiratory and photosynthetic electron chains and their production is enhanced during desiccation/rehydration. Nitric oxide (NO) is a ubiquitous and ...

[EN] Air pollution has dramatically decreased lichen diversity in polluted areas. However, the causes underlying this sensitivity are poorly known, hindering the prevention of biodiversity loss. Nitric oxide (NO) is a ...
[EN] Potato plants were grown in open-top chambers under
three ozone concentrations during two complete cropping
seasons (93 and 77 d in 2004 and 2005, respectively). The
effects of chronic exposure to ozone on leaf ...
Calatayud, V.; García Breijo, Francisco José; Cervero, J; Reig Armiñana, José; Sanz Sánchez, Maria Jose(Elsevier, 2011-07)
Ozone effects on the perennial forb Lamottea dianae were studied in an open-top chamber experiment. Ozone was found to induce reductions in CO 2 assimilation and water use efficiency in the leaves of this species. These ...
