“…Mexico City is among the top five megacities of the world with respect to total human population [34]. Within this megacity, an ecological reserve (Reserva Ecológica del Pedregal de San Ángel, REPSA) was created in 1983, as an effort to preserve a unique xerophytic scrub that was formed after the eruption of the Xitle volcano almost 2 000 years ago [35–37]. Its 237 hectares are currently inhabited by 1 849 native species of plants and animals.…”

This town ain't big enough for both of us…or is it? Spatial co-occurrence between exotic and native species in an urban reserve

Exotic species pose a threat to most ecosystems because of their potential to establish negative interactions with native biota. However, exotic species can also offer resources to native species, especially within highly modified environments such as urban ecosystems. We studied 17 exotic-native pairs of species with the potential to compete with one another, or in which one of the species could offer resources to the other, in an urban ecological reserve located within Mexico City. We used two-species occupancy models to analyze the potential association between the presence of the exotic species and the spatial distribution of the native species, as well as to assess if these species tend to avoid each other (negative spatial interaction) or to co-occur more often than expected under the hypothesis of independent occurrences (positive spatial interaction). Our results revealed few cases in which the exotic species influenced occupancy of the native species, and these spatial interactions were mainly positive, indicated by the fact that the occupancy of the native species was usually higher when the exotic species was also present. Seven of the eight observed non-independent patterns of co-occurrence were evident during the dry months of the year, when resources become scarce for most species. Our results also demonstrate that the observed patterns of species co-occurrence depend on the distance to the nearest urban structure and the amount of herb, shrub, and tree cover, indicating that these habitat features influence whether native species avoid or co-occur with exotic species. Our study represents an important contribution to the understanding of temporal dynamics in the co-occurrence between exotic and native species within urban ecological reserves.

“…The REPSA is now home to 1,849 native and 317 exotic species (REPSA, 2017). As other PUGS, this area is inserted in an urban matrix and provides ecosystem services such as highwater infiltrations to the city and flood regulation (Vargas, 1984;Delgado et al, 1998;Nava-López et al, 2009;Palacio-Prieto and Guilbaud, 2015).…”

“…Previous studies on Mexico City´s geoheritage have focused on Xitle volcano because it is the youngest dated volcano of the SCVF (1670 +/-35 calibrated years before present; Siebe 2000) and hence one of the best preserved, and it fed an extensive lava field now covered by the city, therefore having a strong connec-tion with the urban communities (Figure 1). Those studies have identified main geosites that have great scientific and cultural significance and provide numerous ecosystem services (Palacio and Guilbaud 2015;Guilbaud et al 2021;Nieto-Torres et al 2022). Nevertheless, many other public parks within the city also contain remains of this geoheritage, and the development of research projects in these parks could allow to advance the scientific knowledge while at the same time allow scientists to engage with citizens and stakeholders, with the aim to contribute to environmental conservation, increase people´s resilience to volcanic hazards, and reduce the science-society gap (Topp et al 2018(Topp et al , 2020Sarkki et al 2020;Lièvre et al 2022).…”

Urban geosites are an important resource for science, geoeducation and geotourism that may provide multiple benefits for local communities. The gigantic Mexico City is settled in a paleolake basin sur- rounded by Quaternary volcanic ranges. The SW corner of the city has spread over two of these ranges, Sierra Chichinautzin and the Sierra de las Cruces, leaving few outcrops in the dense urban network that are preserved in public parks. We present here the results of our study of the geological characteristics of two parks managed by local communities. We found surprisingly high geodiversity in these parks and their directly surrounding areas which, along with their accessibility, give them elevated geoeducation and geotourism values. This geodiversity is combined with biodiversity, creating a geo-bio-heritage that is, however, threatened by anthropic activities. We designed geopaths and, as a first approach to the communities, we organized field excursions along them which were highly successful in raising the knowledge and interest of local people on their geo-bio-heritage and also contributed to their aware- ness of anthropic threats that need to be addressed in order to achieve sustainable management for their conservation. Our project hence represents the first step of a strategy to promote the natural heritage to local communities, contribute to its conservation, and reduce the gap between science and society.
