“…the establishment of the same non-native species at two or more locations, decreasing beta-diversity over time (Olden et al, 2011). This situation is already occurring in the area (Magalhães et al, 2011), as well as the probable intra-specific hybridization between X. maculatus and X. variatus (A.L.B. Magalhães, pers.…”

“…Although more than 50 non-native fish species are currently found in Brazilian headwater creeks (Bizerril, Lima, 2001;Magalhães, Jacobi, 2008), a group of seven poeciliids deserve special attention as a threat to native communities due to negative impacts such as changes in the structure of the native fish assemblages and biotic homogenization: the guppy Poecilia reticulata Peters, 1859, sailfin molly P. latipinna (Lesueur 1821), black molly P. sphenops Valenciennes in Cuvier, Valenciennes, 1846, Yucatan molly P. velifera (Regan 1914), green swordtail Xiphophorus hellerii Heckel 1848, southern platyfish X. maculatus (Günther 1866), and variable platyfish X. variatus (Meek 1904) (Alves et al, 2007;Magalhães, Jacobi, 2008;Magalhães et al, 2011). Along with cyprinids, cichlids and osphronemids, these poeciliids are the ornamental fishes most sought by the Brazilian aquarium trade (Coe et al, 2011;Magalhães, Jacobi, 2013b;Assis et al, 2014;Garcia et al, 2014).…”

“…Não bastasse isso, mais uma ameaça ambiental chama a atenção das pessoas que se preocupam com a conservação e uso racional dos ecossistemas brasileiros. O foco agora é dirigido diretamente sobre a integridade dos ecossistemas aquáticos, já bastante ameaçado pelas mudanças propostas no Código Florestal (Magalhães et al 2011) e expansão da usinas hidroelétricas em todo o território nacional. Na Câmara dos Deputados tramita um Projeto de Lei (PL) que, se aprovado, pode causar grandes prejuízos à conservação dos recursos e ecossistemas de água doce brasileiros.…”

“…According to Ab'Saber (2010), the new law may increase the human interference of natural ecosystems and biodiversity by permitting, for example, a reduction in riparian forest cover. The expansion of economic activities such as agriculture, livestock production, and logging that would be sanctioned by the new legislation could lead to considerable environmental impacts on limnic ecosystems and the species that are dependent upon them (Casatti 2010;Tundisi & Tundisi 2010;Magalhães et al 2011;Ferreira et al 2014).…”
