摘要: Records of the gastropod Melanoides tuberculatus (Muller, 1774), family Thiaridae, in Piranhas-Assu River basin Rio Grande do Norte reveal dispersal this native Southeast Asian and East African species into aquatic environments Brazilian semiarid region, including artificial (reservoirs) lotic systems. The eutrophic conditions local waterbodies appear to favor present situation, where invasive reaches extremely high densities, sometimes over 10,000 ind.m-2 as Armando Ribeiro Goncalves Reservoir. These observations indicate immediate need for new studies on spatial distribution its potential impact biodiversity water quality region state. Implantation regular systematic monitoring resources is urgently required.
