Resumo: | Deforestation is a major threat globally, but especially in tropical regions because they are biodiversity strongholds and carbon storehouses. Some studies have reported changes in species richness and composition in lotic ecosystems with increased forest-loss in their catchment, presumably resulting from the replacement of sensitive taxa by more resistant or tolerant taxa. Also, sensitive taxa respond to deforestation in a non-linear manner and fish and macroinvertebrates have different sensitivities to landscape pressures. Therefore, it is useful to determine the effects of forest-loss on widespread sensitive or threshold taxa in aquatic ecosystems. We used Threshold Indicator Taxa Analysis (TITAN) to assess forest-loss and land use history impacts in 92 eastern Amazonian stream sites. We determined TITAN peak-change thresholds for fish at 1% and 6% of forest-loss at total-catchment and local-riparian spatial extents, respectively, and at 2% and 40% of land-use intensity change at total-catchment and local-riparian spatial extents, respectively. For macroinvertebrates, TITAN peak-change thresholds were 1% and 11% of forest loss at total-catchment and local-riparian spatial extents, respectively, and at 3% of land-use intensity change for both total-catchment and local-riparian spatial extents. Because of these thresholds, inherent ecoregional variability and key literature, we have three major recommendations. 1) Logging should be prohibited in riparian reserves that are at least 100-m wide on each side of headwater streams and in a network of catchments across all biomes and as many landscape types as possible. 2) An ecologically and statistically rigorous monitoring program with standard methods should be implemented to assess and regulate land uses better. 3) Conservation planning areas should consider aquatic biota as well as terrestrial biota. |

Alguns estudos relataram mudanças na riqueza e composição de espécies em ecossistemas lóticos com aumento da perda de floresta em sua bacia hidrográfica, presumivelmente resultante da substituição de táxons sensíveis por táxons mais resistentes ou tolerantes. Além disso, táxons sensíveis respondem ao desmatamento de maneira não linear e peixes e macroinvertebrados têm diferentes sensibilidades às pressões da paisagem. Portanto, é útil determinar os efeitos da perda de floresta em táxons sensíveis ou limiares generalizados em ecossistemas aquáticos. Usamos Threshold Indicator Taxa Analysis (TITAN) para avaliar a perda de floresta e os impactos do histórico de uso da terra em 92 locais de riachos da Amazônia oriental. Nós determinamos limites de mudança de pico TITAN para peixes em 1% e 6% de perda de floresta na captação total e extensões espaciais ribeirinhas locais, respectivamente, e em 2% e 40% de mudança de intensidade de uso da terra na captação total e extensões espaciais locais-ciliares, respectivamente. Para macroinvertebrados, os limiares de mudança de pico do TITAN foram de 1% e 11% de perda de floresta na bacia total e extensões espaciais ribeirinhas locais, respectivamente, e em 3% de mudança de intensidade de uso da terra para a bacia total e espacial ribeirinha local. extensões. Por causa desses limiares, variabilidade ecorregional inerente e literatura chave, temos três recomendações principais. 1) A exploração madeireira deve ser proibida em reservas ciliares com pelo menos 100 m de largura em cada lado dos córregos de cabeceira e em uma rede de bacias hidrográficas em todos os biomas e tantos tipos de paisagem quanto possível. 2) Um programa de monitoramento ecologicamente e estatisticamente rigoroso com métodos padrão deve ser implementado para avaliar e regular melhor os usos da terra. 3) As áreas de planejamento de conservação devem considerar tanto a biota aquática quanto a biota terrestre.CNPq - Conselho Nacional de Desenvolvimento Científico e TecnológicoFAPEMIG - Fundação de Amparo à Pesquisa do Estado de Minas GeraisCAPES - Coordenação de Aperfeiçoamento de Pessoal de Nível SuperiorFAPESP - Fundação de Amparo à Pesquisa do Estado de São PauloOutra AgênciaengUniversidade Federal de Minas GeraisUFMGBrasilICB - DEPARTAMENTO DE BIOLOGIA GERALEcological IndicatorsBiodiversidadeDesmatamento - AmazonasRios - BrasilFlorestas tropicais - AmazôniaMadeira - ExploraçãoFlorestas - ConservaçãoEcological thresholdsAmazonian deforestationSmall streamsIndicator taxaIntegrityBiodiversityLow forest-loss thresholds threaten Amazonian fish and macroinvertebrate assemblage integrityBaixos limiares de perda florestal ameaçam a integridade da assembléia de peixes e macroinvertebrados amazônicosinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://www.sciencedirect.com/science/article/pii/S1470160X21004386?via%3DihubRenato Tavares MartinsJanaina Gomes de BritoKarina Dias da SilvaCecília Gontijo LealRafael Pereira LeitãoVivian Campos de OliveiraJosé Max Barbosa de Oliveira JúniorSílvio Frosini de Barros FerrazFelipe Rossetti de PaulaFábio de Oliveira RoqueNeusa HamadaLeandro JuenJorge Luiz NessimianPaulo dos Santos PompeuRobert M.

Deforestation is a major threat globally, but especially in tropical regions because they are biodiversity strongholds and carbon storehouses. Some studies have reported changes in species richness and composition in lotic ecosystems with increased forest-loss in their catchment, presumably resulting from the replacement of sensitive taxa by more resistant or tolerant taxa. Also, sensitive taxa respond to deforestation in a non-linear manner and fish and macroinvertebrates have different sensitivities to landscape pressures. Therefore, it is useful to determine the effects of forest-loss on widespread sensitive or threshold taxa in aquatic ecosystems. We used Threshold Indicator Taxa Analysis (TITAN) to assess forest-loss and land use history impacts in 92 eastern Amazonian stream sites. We determined TITAN peak-change thresholds for fish at 1% and 6% of forest-loss at total-catchment and local-riparian spatial extents, respectively, and at 2% and 40% of land-use intensity change at total-catchment and local-riparian spatial extents, respectively. For macroinvertebrates, TITAN peak-change thresholds were 1% and 11% of forest loss at total-catchment and local-riparian spatial extents, respectively, and at 3% of land-use intensity change for both total-catchment and local-riparian spatial extents.
