Belowground fungi are key sentinels in forest soils vulnerable to pentachlorophenol pollution: a mechanistic study in Quercus suber forests
Publication . Varela, Adélia; Pereira, Cristina Silva
"Atmospheric release of persistent organic pollutants (POPs) constitutes a silent threat through chronic contamination of soils at global scale; yet fundamental understanding of their occurrence, sources and fate is still largely lacking. The above statement has inspired the working hypothesis of this doctoral thesis – active sources of pentachlorophenol (PCP) pollution are reaching the soils of emblematic cork oak forests (Chapter II and III), hence altering the functioning of the belowground mycobiota (Chapter III and IV) that act as buffer against the disturbance caused by the biocide (Chapter III and IV).(...)"
Revealing specialisation events induced by pollutants in belowground fungal communities
Publication . Martins, Celso Filipe Ferreira; Pereira, Cristina Silva
"Chemical pollution has been in the centre of scientific discussion for decades, mainly due to toxicological motives. Pollution and climate change is leading to associated geological/geochemical and atmospheric alterations that negatively impact all ecosystems, including humans. To date our understanding of the environmental impact of pollution and climate change is still very limited. Among the ecological groups that are affected by pollution the “unseen “majority” are the microbial communities especially fungi, that dominate most habitats on Earth. Several studies exist focusing on the effects of organic pollutants towards microbes, especially considering their overall toxicity and degradation with emphasis on fungi due to their impressive catabolic capacities. However, how exposure to toxicants impacts the dynamics of microbial communities remains poorly understood.(...)"
