Inventari micològic de les zones enjardinades del Campus Montilivi

Abstract

In this study, a mycological inventory was conducted in the landscaped areas of the Montilivi Campus at the University of Girona, with the aim of understanding the structure, composition, and diversity of the fungal community in the area. Despite being a relatively unknown group, fungi play a crucial role in ecosystems and provide important ecosystem services to humans. To develop the inventory, nine plots distributed across the entire campus were sampled, covering a total area of 12,736 m2 and ranging in elevation from 98 to 116 meters above sea level. Species identification was carried out on-site, with the abundance of each species also recorded. Only species that raised doubts were collected and analyzed in the laboratory, minimizing the impact on the sampled environment. Field data was collected in Excel and supplemented with information on the family and ecology of each species. Subsequently, all inventoried species were compiled in a table along with relevant information, and different sector graphs were created to represent the representation of each family and ecological role (saprobes, mycorrhizal, or parasitic) within the fungal community. A list with relevant information on the most abundant species in each group was also provided. The abundance of individuals and their dominant ecology in each sampled plot was analyzed. Finally, the fungal community's diversity in the area was assessed using the Shannon-Wiener index (H') and Evenness (E). The inventory includes 24 species, with one belonging to the Ascomycota group and the rest to the Basidiomycota group. The dominant family in the study area, accounting for over half of the community, is Psathyrellaceae. In terms of ecological roles, saprophytes represent 83% of the community, while mycorrhizal species are in the minority, and no parasites were found. Although the results may not be considered truly representative of the community, as data collection over a longer period or the use of high-throughput sequencing techniques on soil samples from the study area would be required, and the environmental conditions, such as precipitation, have not been favorable for fungal fruiting, diversity indices indicate that the fungal community in the study area is in a good state in terms of diversity
