How do patch burnings affect ant communities and seed removal in a subtropical grassland?
Disturbances modify local abiotic properties, habitat structure and resource availability, shaping community assembly and ecological interactions. Open ecosystems have an evolutionary relationship with fire. We evaluated the effects of patch burnings on grassland ant communities and patterns of seed removal. We established 14 plots of 10 m2 in pairs in a disturbance-suppressed grassland in South Brazil. A random plot of each pair was burned, and another plot was the control. We accessed ant communities with pitfall-traps and sweeping net, and seed removal with seed traps in all plots prior the experimental fires, and then on three occasions following fires. We recorded 57 ant species belonging to 29 genera. Ant species composition did not significantly vary between treatments neither did ant body size. We detected significantly positive fire effects on ant richness after 1 month and 12 months, mediated by the increase in plant species richness in burned plots. Mean seed removal rates were increased in burned plots after 1 month. We showed that prescribed patch burnings in fire-prone grasslands promoted ant richness, and their foraging activity. Our study may serve as a basis for conservation decisions, showing the importance of maintenance of disturbances in grasslands.
期刊介绍：
Perspectives in Ecology and Conservation (PECON) is a scientific journal devoted to improving theoretical and conceptual aspects of conservation science. It has the main purpose of communicating new research and advances to different actors of society, including researchers, conservationists, practitioners, and policymakers. Perspectives in Ecology and Conservation publishes original papers on biodiversity conservation and restoration, on the main drivers affecting native ecosystems, and on nature’s benefits to people and human wellbeing. This scope includes studies on biodiversity patterns, the effects of habitat loss, fragmentation, biological invasion and climate change on biodiversity, conservation genetics, spatial conservation planning, ecosystem management, ecosystem services, sustainability and resilience of socio-ecological systems, conservation policy, among others.
