Supplemental Information (presence-absence matrix) from “Save the survivors: the remarkable ant diversity of the last protected fragment of savanna in Southern Brazil”.|生物多样性数据集|生态研究数据集

The dataset is a presence-absence matrix, obtained for 136 ant species sampled at the Parque Estadual do Cerrado (Cerrado State Park - CSP). The park has 420 ha and is located 10 km northeast of the urban perimeter of Jaguariaíva (24°10'S 49°39'W). We established three 380 m transects, separated from each other by 1 km. Along each transect, we marked 20 sampling points, spaced by 20 m. The points were alternated to sample the ground-dwelling ants on the soil surface and the arboreal ants on the trees, totaling 60 samples, 30 on soil, and 30 arboreal. In both strata, we used pitfall traps, which consisted of a small plastic cup of 250 ml, 8.5 cm high, and 7.8 cm in diameter. To collect the ground-dwelling ants, four pitfall traps containing water and detergent were arranged in the soil in a square grid of 2.5m x 2.5m. In the arboreal stratum, four pitfall traps, containing human urine diluted 1:2 in water and detergent were fixed on the trees at approximately 2.5 m high. The pitfall traps remained installed for 48 hours; after that, the contents of the four pitfalls in each point were combined into a single plastic bag, making up a single composite sample. The samples were transported to the Laboratório de Sistemática e Biologia de Formigas at Universidade Federal do Paraná (UFPR), Curitiba, Brazil, where the collected ants were sorted, mounted, and identified to species whenever possible.
