The biota inhabiting the Suquía River Basin is described in this chapter.Comments on the species of fish, birds, invertebrates and aquatic plants registered in this system are included. Along the basin, different factors generate a non-continuous mosaic of abiotic conditions at temporal and spatial levels, which, in turn, structure the biotic communities.The hydrological system of the river drainage consists of three sections. The upper basin in a mountainous area with headwaters and torrential rivers flowing into the San Roque Reservoir.The middlebasin with drainage areas belonging to the eastern slope of the Sierras Chicas, together with the drainage area of the city of Córdoba. The lower basin is located downstream from the city of Córdoba flowing intothe Mar ChiquitaLake, where the river meanders exhibiting little flow. The species of the different groups change according to the characteristics of each section. In this chapter,endemic and introduced species are discussed. The bivalve species that inhabit the Suquía River are not native and the cause of their introductionis explained. Authors also specify the anthropic factors that negatively impactwater, bird and invertebrate species in the river.
