Resumo: | Biological invasions are leading several species to extinction and are projected as a main driver of biodiversity changes in lakes for this century. However, the knowledge of their impacts on the Neotropical ichthyofauna over time remains largely incipient, especially when considering the functional diversity of native communities. Here we aim to identify the effects of non-native species, especially the non-native piscivorous Cichla kelberi and Pygocentrus nattereri, on the functional diversity of the native ichthyofauna of the Carioca Lake, Middle Rio Doce basin, state of Minas Gerais. Using fish occurrence data for eight years from 1983 to 2010 combined with an ecomorphological-trait analysis, we found that while the native species richness dropped to 56%, the functional richness is only 27% of that found before introductions. In other words, more than species, the ichthyofauna suffered an impressive decline in the range of functional traits, which can further have severe impacts on ecological processes within that system. When considering all the components of the current ichthyofauna (native and non-native species), neither taxonomic nor functional richness have changed over time. However, even keeping biodiversity levels, non-native species are not able to fully compensate for the extinct native ones in terms of functions. |

Entretanto, o conhecimento dos impactos sobre a ictiofauna Neotropical ao longo do tempo permanece bastante incipiente, especialmente quando se considera a diversidade funcional de comunidades nativas. Neste estudo, nós procuramos identificar os efeitos das espécies não nativas, especialmente os piscívoros não nativos Cichla kelberi and Pygocentrus nattereri, sobre a diversidade funcional da ictiofauna da Lagoa Carioca, bacia do médio rio Doce, Minas Gerais. Utilizando dados de ocorrência de oito anos entre 1983 e 2010, combinados a uma análise de atributos ecomorfológicos, observamos que a riqueza de espécies decaiu a 56%, enquanto a riqueza funcional é de apenas 27% da encontrada antes das introduções. Ou seja, mais do que espécies, a ictiofauna sofreu um declínio significativo na amplitude de atributos funcionais, o que pode levar a impactos severos em processos ecológicos neste sistema. Ao considerar todos os componentes da ictiofauna atual (espécies nativas e não nativas), as métricas de riqueza não sofreram alterações ao longo do tempo. Entretanto, mesmo mantendo os níveis de biodiversidade, espécies não nativas não são capazes de compensar totalmente as espécies nativas extintas em termos funcionais.CNPq - Conselho Nacional de Desenvolvimento Científico e TecnológicoFAPEMIG - Fundação de Amparo à Pesquisa do Estado de Minas GeraisOutra AgênciaengUniversidade Federal de Minas GeraisUFMGBrasilICB - DEPARTAMENTO DE BIOLOGIA GERALNeotropical IchthyologyBiodiversidadeExtinção (Biologia)Peixe de água doceBioinvasãoBiodiversity erosionBiological invasionsFunctional traitsNon-native fishRio Doce basinDrastic reduction of the functional diversity of native ichthyofauna in a neotropical lake following invasion by piscivorous fishesRedução drástica da diversidade funcional da ictiofauna nativa em um lago neotropical após invasão de peixes piscívorosinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://www.scielo.br/j/ni/a/yZ6hSB4rWVYYJvFZZWQ3qbd/?lang=en#Carla Patrícia de SouzaCarlos Alberto de Sousa Rodrigues FilhoFrancisco Antônio Rodrigues BarbosaRafael Pereira Leitãoapplication/pdfinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFMGinstname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGLICENSELicense.txtLicense.txttext/plain;
