- Bryophyte diversity at a site contaminated by hydrocarbons from abandoned oil wells in Patagonia, Argentina Agustina C. Cottet Matias Soto-Mancilla Natalia V. Fernández Biología mosses hornworts liverworts hydrocarbon tolerance Arbuscular mycorrhizae Background and Aims: Bryophytes are distributed worldwide and play a crucial role in disturbed sites, acting as pioneer organisms in ecological successions following disturbances. The objective of this work was to study bryophytes growing in relation to substrates contaminated with crude oil and to analyze their arbuscular mycorrhizal status.Methods: Samples were collected along a northern Patagonian stream located in the steppe (San Carlos de Bariloche, Río Negro, Argentina). The examined specimens were collected along the stream’s margins before, during and after the spill from the abandoned oil wells. Bryophyte species were identified based on morpho-anatomical characteristics. The abundance of arbuscular mycorrhizae (AM) in the plants and the number of AM spores in the substrate were also analyzed.Key results: Sixteen bryophyte species were identified; one hornwort, two liverworts and the rest were mosses. Although certain plants were mainly associated with some of the locations studied, bryophyte communities in general did not show significant variations along the pollution gradient, while AM inoculum exhibited variations.Conclusions: This study suggests that certain bryophyte species can tolerate the conditions generated by crude oil contamination and establish themselves in the early stages of environmental succession (e.g. on solidified crude oil beds). These results provide a basis for future ecological restoration efforts. 2024 artículo científico 0187-7151 https://www.redalyc.org/articulo.oa?id=57478628021 https://www.redalyc.org/journal/574/57478628021/ https://www.redalyc.org/journal/574/57478628021/html/ https://www.redalyc.org/journal/574/57478628021/57478628021.epub https://www.redalyc.org/journal/574/57478628021/movil 10.21829/abm131.2024.2379 en http://www.redalyc.org/revista.oa?id=574 Acta Botanica Mexicana application/pdf Instituto de Ecología, A.C.
