“…2020; Sánchez-Hernández et al. 2022a). On the other hand, the high production of dung by domestic animals in the area, mainly stray and feral dogs (Carnivora: Canidae) (Zúñiga and Sarmiento 2014; Gómez-Méndez, unpublished data), is a resource that eventually replaces the absence of native mammals in cities (Cave 2005; Ramírez-Restrepo and Halffter 2016b); in this way, the exploitation of these resources allows the maintenance, to some extent, of dung beetle assemblages in urban and peri-urban areas (Carpaneto et al.…”

“…Both baits offset the two main trophic habits of Scarabaeinae and represent two frequently used, effective attractants that have been successfully used in previous dung beetle diversity studies in nearby regions (Sánchez-Hernández et al. 2018, 2022a). At each sampling habitat, we placed six pitfall traps in each of two sites (replicates; n = 24 total traps per sampling).…”

In this study, we compared the Scarabaeinae (Coleoptera) assemblages between two contrasting habitats (conserved forest versus urban habitat), located between the boundary of an urban zone and a protected area within the Mexican state of Chiapas. We collected 1003 individuals of 22 species and 12 genera. The composition of assemblages was similar between habitats, with a high species dominance. However, the identity of the dominant species differed between habitats, with 11 species considered indicators of one of the two conditions (five species in the conserved forest sites and six species in urban habitat sites), whereas three other species exhibited generalist habits. Large paracoprids predominate in the conserved forest, and small paracoprids in the urban habitat. The apparent homogeneity in the dung beetle assemblages probably is due to the high density of domestic and feral animals replacing native mammals and is promoted by the loss of forest-dependent species caused by continuous landscape fragmentation. Nonetheless, the association of some species with forest habitat and the differences in the structure of functional groups indicate the importance of conserving these forest remnants, which would help to mitigate the negative impact of urbanised areas, as these species are generally sensitive to the habitat fragmentation process.

“…Therefore, more complex and robust studies should disentangle the drivers of species diversity distribution, and how each driver is contributing to these patterns. In addition, dung beetles are highly mobile and successful dispersers (Sánchez- Hernández et al, 2022). So they can respond quickly to environmental variation in space, show compensatory dynamics and may be less affected by an unknown variable in site history compared to organisms with little dispersal (Blüthgen et al, 2022).…”

Studying mechanisms that impact and maintain species diversity in space and time is one of the most important questions in ecology and conservation (Castro et al., 2020;Chesson, 2000). To achieve this goal, it is important to evaluate multiple scales and metrics of biodiversity in response to ecological processes (Barton et al., 2013).Several studies have developed models and theories to assess the impacts that climate change can directly and indirectly cause on species diversity (Norberg et al., 2012). To assess these impacts, longterm assessments associating climate change with species diversity patterns are necessary. Nevertheless, due to the long time to have answers that are needed immediately, these analyses become unfeasible and impractical. In addition, since variation in temporal trends is typically based on comparison in more than one location, making it also a spatial pattern (Blüthgen et al., 2022), a suitable alternative
