Resumo: | Experimentation in ecology has been widely addressed by researchers due to its ability to control environmental and biological effects of interest, and thus obtain more robust scientific evidence. However, in recent years there has been a growing debate about the “reproducibility crisis” in science. The main issue in the lack of reproducibility of the results is the failure of the scientific theory validation process that occurs through the accumulation of evidence by Works replicated by several researchers. Considering the continental aquatic ecosystems, for example, in the last decades, several experiments have sought to explain the consequences generated by changes in the composition and wealth of communities on ecosystem functions and services. Thus, within the context of experimental replication in ecology of continental aquatic environments, the present study had as objectives, divided into three chapters: (i) to evaluate experimental studies in aquatic ecology through a systematic review; (ii) discuss the replicability and reproducibility of the most prominent experiments in aquatic ecology and (iii) quantify the global effect of biodiversity on the functioning of continental aquatic ecosystems through a meta-analysis. In general, the themes addressed experimentally in aquatic ecology are quite diverse and dynamic over time. In the first decades there was an increase in the number of new topics developed through experiments. In recent decades, researchers have sought to focus mainly on replicating the different dimensions of ecological questions that were initially tested. It is important to note, however, that the confirmation or not of the original results of the experiments in aquatic ecology occurs at different levels of secondary replication. Exact replications, for example, do not exist, since there is always, to some degree, heterogeneity between studies. On the other hand, in general, the original questions replicated can be generalized to other organisms and ecosystems. However, at the same time it is necessary caution when interpreting generalizations in nature, due to the different conditions of heterogeneity that the experiments are manipulated. Although it is known that biodiversity improves the functioning of ecosystems, due to several experimental evidences that corroborate this premise, given the different experimental conditions that a given hypothesis test of the relationship between biodiversity and ecosystem functioning may occur, the effect of this relationship may be overestimated or underestimated when jointly comparing individual results in a meta analytical synthesis. In general terms, the ecological issues addressed in the experiments are replicated at different levels, considering different conceptual and methodological approaches to reproduce similar results and search for ecological patterns. |

No entanto, nos últimos anos tem havido um crescente debate sobre a “crise de reprodutibilidade” na ciência. A principal questão na falta de reprodutibilidade dos resultados está na falha do processo de validação de teorias científicas que se dá através do acúmulo de evidências por trabalhos replicados por diversos pesquisadores. Considerando os ecossistemas aquáticos continentais, por exemplo, nas últimas décadas, diversos experimentos têm buscado explicar as consequências geradas por mudanças na composição e riqueza das comunidades sobre as funções e serviços ecossistêmicos. Assim, dentro do contexto de replicação experimental em ecologia de ambientes aquáticos continentais, o presente trabalho teve como objetivos, divididos em três capítulos: (i) avaliar os estudos experimentais em ecologia aquática através de uma revisão sistemática; (ii) discutir a replicabilidade e reprodutibilidade dos experimentos de maior destaque na ecologia aquática e (iii) quantificar o efeito global da biodiversidade sobre o funcionamento de ecossistemas aquáticos continentais através de uma meta-análise. Em geral, os temas abordados experimentalmente na ecologia aquática são bastante diversos e dinâmicos ao longo do tempo. Nas primeiras décadas houve um aumento no número de novos tópicos desenvolvidos através de experimentos. Nas últimas décadas, os pesquisadores buscaram focar principalmente na replicação em diferentes dimensões das perguntas ecológicas já testadas inicialmente. É importante destacar, no entanto, que a confirmação ou não dos resultados originais dos experimentos em ecologia aquática se dá em diferentes níveis de replicação secundária. Replicações exatas, por exemplo, são inexistentes, visto que sempre há, em algum grau, uma heterogeneidade entre os estudos. Por outro lado, em geral, as perguntas originais replicadas, podem ser generalizadas para outros organismos e ecossistemas. Entretanto, ao mesmo tempo é necessário ter cautela na interpretação das generalizações na natureza, devido às diferentes condições de heterogeneidade que os experimentos são manipulados, e próprios dentro da disciplina de Ecologia. Embora seja conhecido que a biodiversidade melhora o funcionamento dos ecossistemas, por diversas evidências experimentais que corroboram essa premissa, dada as diferentes condições experimentais que um determinado teste de hipóteses da relação biodiversidade e funcionamento dos ecossistemas podem ocorrer, o efeito dessa relação poderá estar superestimada ou subestimada quando comparados conjuntamente os resultados individuais em uma síntese meta-analítica. Em termos gerais, as questões ecológicas abordadas nos experimentos são replicadas em diferentes níveis, considerando diferentes abordagens conceituais e metodológicas para reproduzir resultados semelhantes e buscar por padrões ecológicos.Submitted by Luciana Ferreira (lucgeral@gmail.com) on 2020-12-17T12:13:16Z No. of bitstreams: 2 Tese - Leticia Pereira dos Santos - 2020.pdf: 2951720 bytes, checksum: c126006ea4f2fc5e43332bb40889e101 (MD5) license_rdf: 805 bytes, checksum: 4460e5956bc1d1639be9ae6146a50347 (MD5)Approved for entry into archive by Luciana Ferreira (lucgeral@gmail.com) on 2020-12-18T12:51:36Z (GMT) No. of bitstreams: 2 Tese - Leticia Pereira dos Santos - 2020.pdf: 2951720 bytes, checksum: c126006ea4f2fc5e43332bb40889e101 (MD5) license_rdf: 805 bytes, checksum: 4460e5956bc1d1639be9ae6146a50347 (MD5)Made available in DSpace on 2020-12-18T12:51:36Z (GMT).
