Aquatic macroinvertebrates in Madeira Island (Portugal) streams: diversity and distribution
The Madeira Island (Portugal; 32°24’–33°07’N, 16°16–17°16’W; 796 km2) is an oceanic island located in the North Atlantic, about 980 km south of Portugal and about 700 km west of the African coast. The presence of freshwater invertebrates in oceanic islands has always raised questions concerning disp...
