Data from: Seasonal dynamics in terrestrial insect communities after the impact of the Brumadinho Tailings Dam Disaster

This dataset contains species richness, Sorensen dissimilarity and its
components of species turnover (total and proportional) and
nestedness-resultant (total and proportional) data for five groups of
insects (ants, bees, butterflies, dung beetles, and termites) sampled in
20 sites across three habitat categories: legally protected areas (PRO),
reference sites (REF), and forest fragments adjacent to the mudflow (MUD),
conducted in the municipality of Brumadinho, Minas Gerais State,
southeastern Brazil. The region gained international attention following
the collapse of a tailings dam on 25 January 2019, owned by the Brazilian
mining company Vale S.A. The original vegetation of the region was
predominantly Atlantic Forest, mainly composed of semideciduous forests,
with patches of savanna and rocky-shrubby vegetation at higher altitudes,
owing to its location near the transition zone between the Atlantic Forest
and Cerrado biomes. Eight sites were in legally protected areas (PRO),
with which we aimed at understanding the best possible background scenario
in the region: three in Special Protection Area of Rio Manso (which
sources water to Belo Horizonte Metropolitan region), three in Inhotim
Private Reserve, and two in Rola Moça State Park. Six additional sites
were classified as reference areas (REF), consisting of secondary forest
patches within the landscape unaffected by the tailings but potentially
subject to other disturbances.
