“…Individuals from Hydropsychidae are selective in choosing the substrate and are found in clean waters or less impacted sites, indicating the sensibility of this group in degraded water bodies (Queiroz et al, 2018;Clemente et al, 2019). It therefore could inform that the presence of these organisms in the Faxinalzinho stream might also indicate good environmental quality.…”

Several studies indicate that negative impacts on water quality are minimally related to silviculture. We analyzed the water quality of a stream in a silvicultural region in southern Brazil, considering the relationship between the components of the landscape and biotic quality indexes, merging physical and biological descriptions of the macroinvertebrate community and environment. We selected three points in the Faxinalzinho stream to collect macroinvertebrate samples and to perform perceptual analysis from September to December/2014, applying the Biological Monitoring Working Party (BMWP') and the Rapid Assessment Protocol for Habitat Diversity (RAPHD). Diversity metrics and a Non-metric Multidimensional Scaling (NMDS) were also applied to explore variations in the aquatic community abundance matrix, associating the data to Land Use/Land Cover. A total of 569 individuals was recorded, distributed in 27 taxa. The results showed good water quality in the studied points, mainly when compared to other studies regarding urban rivers. However, we found negative effects in the site with higher silviculture land cover, presenting acceptable water quality (BMWP'= 66) and altered environmental conditions (RAPHD= 51), while the other sites presented excellent water quality (BMWP'= 127-131) and natural environment (RAPHD= 85-91).

“…Many countries have adopted macroinvertebrates as bioindicators of water quality, using the family level (Queiroz et al, 2018;Cortelezzi et al, 2019;Castro et al, 2020). However, Germany stands out as the only country that requires the use of species-level identification in its saprobic method (Jones, 2008).…”

Aim Macroinvertebrates are extensively employed as bioindicators for evaluating how stream ecosystems respond to alterations in physical and chemical habitats caused by human activity. Although family-taxonomic level is usually used to identify macroinvertebrates in biomonitoring programs, coarser taxonomic resolution may provide similar information. We aim to evaluate taxonomic sufficiency by comparing macroinvertebrate communities at the order and family levels to differentiate the effects of different land uses. Methods We conducted colonization experiments using artificial substrates in streams representing three land use types: urban (U, n=3), intensive agriculture - dairy production (AD, n=4), and extensive cattle ranching (CR, n=4). Results We obtained similar results using both taxonomic levels, which effectively distinguished the impacts of different land uses. In the sites examined, the majority of indicator groups exhibited only one family per order, with the exception of Ephemeroptera (Leptophlebiidae, Baetidae, and Caenidae). Notably, Baetidae and Caenidae were more prevalent in streams associated with extensive cattle ranching (CR). Conclusions Although this study provides a clear precedent, further investigation of these systems and other land uses (e.g., afforestation) is needed to validate this pattern. Coarser taxonomic assessment holds potential as a cost-effective method for stream monitoring and assessment in Uruguay.

“…In this sense, the group of invertivores was also highlighted, since the mentioned environmental quality allows a considerable increase in the richness and abundance of benthic and nektonic macroinvertebrates (Queiroz et al 2018). Abundant organisms, as the number of resources available in the region is also abundant (Rocha 2018) because it is a depositional area for most of the period and having added to this fact, the discharges from the agroindustry (Camargo et al 2019, Vieira et al 2021.…”

Este estudo apresenta os resultados da diversidade de peixes em um trecho do Rio dos Bois, um manancial de Cerrado, localizado no noroeste do Goiás, Brasil. Sendo um importante tributário das cabeceiras do rio Araguaia, bacia Araguaia-Tocantins, que possui importantes atributos na manutenção da biota deste complexo ecossistema, e parte deste mosaico do Cerrado. A região estudada, compreende a calha principal do Rio dos Bois, da sua cabeceira até a foz do Rio Formiga. As amostragens da ictiofauna foram efetuadas ao longo de duas estações climáticas da região (seca e chuvosa), realizadas em junho/2021 e novembro/2021, respectivamente. As amostragens foram realizadas em 5 pontos amostrais, distribuídos equidistantes de montante à jusante, no Rio dos Bois. Como resultado registrou-se 15.645 espécimes distribuídos em uma riqueza de 46 espécies. Neste estudo, os resultados foram avaliados por testes ecológicos, tais como, frequência de ocorrência, Dominance_D, Simpson_1-D, Shannon_H’, Evenness_e^H/S, Brillouin, Menhinick, Margalef, Equitability_J, Fisher_alpha, Berger-Parker e Chao-1. E analisados pelo teste de normalidade no Tukey test e ANOVA-One way. Sendo possível identificar os locais amostrais mais diversos, assim como os pontos que apresentaram divergência entre alta taxa de captura e baixa diversidade. Indicando que, alguns sítios apresentam maior importância de conservação que outros, vislumbrando futuras ações prioritárias a preservação ambiental.
