GARCIA, Rocío; GOLLO, Maira; VILLAGRA, Elizabeth  e  GOMEZ, Jonatan. Species of lichenized fungi associated with different land uses in the Luján district (Buenos Aires Province, Argentina). Rev. Mus. Argent. Cienc. Nat. [online]. 2023, vol.25, n.2, pp.165-175. ISSN 1853-0400.  http://dx.doi.org/10.22179/revmacn.25.780.

In the district of Luján (Buenos Aires Province, Argentina), the lichen community is almost unknown. Even more unknown is its relationship with the different land uses. The objec tives of the present work are: (1) to identify the species of lichenized fungi associated with the different land uses within the territory belonging to this district and (2) to extend the knowledge about the lichenized fungi com munity of the district. Corticolous lichenized fungi have been surveyed in areas with different land uses (urban, residential, and agricultural) and the association between the recorded species has been statistically explored, as well as the identity of indicator species for each type of land use. A total of 41 species were recorded. All indicator species recorded here are considered toxitolerant. The Urban zone can be clearly separated from the other zones by the presence of the species that inhabit it. The Agricultural and Residential zones cannot be clearly separated. The Residential zone is surrounded by large areas of agricultural and livestock use. This situation is common in the town of Luján, where the transition from residential to agricultural areas is abrupt and this would explain the difficulty in separating the agricultural and residential areas through their lichenized fungi community. In the present work, we are able to determine which are the indicator species of each zone according to their land use and for the first time we list corticolous lichenized fungi species belonging to the Luján district.
