“…However, the decrease in forest cover favored the presence of the habitat-generalist scorpion T. stigmurus. This species is synanthropic, with a greater abundance in urban regions than in natural ones (Amado et al, 2021;Foerster et al, 2021Foerster et al, , 2022. Previous studies indicated that Atlantic Forest scorpion assemblages are highly sensitive to changes in habitat at a local or landscape scale (Lira et al, 2016(Lira et al, , 2020(Lira et al, , 2021.…”

Urban landscapes restrain the distribution of forest‐dwelling species, which may be related to challenging conditions that impair body condition. The dynamics in urban areas lead to the simplification of communities that inhabit forest patches in cities with the turnover of sensitive species for opportunistic ones. In this study, we investigated the effect of urbanization on the body condition and diversity of scorpions at the landscape scale. Sampling was carried out in 10 forest patches in an urban matrix in Brazil, originally covered by a tropical rainforest. The surroundings of the landscape of each forest patch were characterized through the amount of forest, agriculture, and urban land cover. Individual body length, dry, lipid, and muscular masses were used as proxies of Tityus pusillus body condition. In total, 147 scorpions were collected, belonging to the species Ananteris mauryi, T. pusillus, T. stigmurus, and T. neglectus. Forest cover explained 28% of species variation. There was a positive relationship between forest cover and T. pusillus and A. mauryi abundances, while T. stigmurus was negatively affected by forest cover. Species richness and total scorpion abundance were not influenced by landscape metrics. In terms of body condition, only females of T. pusillus were affected by landscape variables, with individuals showing higher body mass with an increase in forest cover. Our results suggest that urban forests can support scorpion assemblages. However, there is a turnover in specialist forest species for opportunistic species. Forest cover is a crucial factor in maintaining healthy scorpion populations in urban areas.
