Data for: Madicolous insects from Atlantic forest and Amazon mountains (Brazil)

<p>The dataset consist on abundance values of madicolous insects - aquatic organisms that inhabit thin layers of water - recorded in three mountains of the Atlantic Rainforest (G1, G2, and G3) and in one Amazon mountain (G4). The distribution of sampling sites cover the full elevational range of each region, from 0 to 2,800 m a.s.l. in the Atlantic Forest and from 90 to 3,000 meters a.s.l. in the Amazon. A total of 109 sampling sites were investigated, where <span>physico-chemical parameters of water (temperature, pH, dissolved oxygen and conductivity), g</span><span>eographic coordinates and the altitude were also obtained.</span></p>
