“…We chose to include landscape metrics in our study to better investigate the responses of the highly sensitive group of organisms to variations in the environment. Indeed, a number of studies have shown that the micro-basin landscape encompasses essential metrics for the environmental quality of streams and their biota (Compin & Céréghino 2007, Deegan et al 2011, Brito et al 2018.…”

“…To avoid pseudoreplication, the individual samples were pooled across the segments and transects of the same stream. We used the EPT as a biological tool because it comprises organisms with low dispersal capacity, high biological diversity, and sensitivity to environmental change (Brito et al 2018). Immature specimens were sampled in 16 headwater streams (1st to 3rd order -Strahler 1957) in September and October 2017.…”

“…At a local scale, the community of aquatic insects found in impacted streams varies at both at the taxonomic level (e.g., species richness, composition, and abundance) and in terms of its functional feeding groups (FFGs). These changes may be associated with the variation in abiotic parameters, such as that provoked by the loss of the riparian vegetation, which reduces the input of allochthonous matter (Brito et al 2018, Castro et al 2018. The sunlight penetrating to the channel heats the water, while also decreasing oxygenation and favoring the growth of algae and macrophytes, with the proliferation of these photosynthetic organisms altering the basis of the food chain, favoring the occurrence of predatory insects (Astudillo et al 2016).…”

“…Ecological studies that evaluate the association between the trophic relationships of the EPT and the variation in abiotic parameters are relatively recent in the Amazon region (Luiza-Andrade et al 2017a, Brito et al 2018, Shimano et al 2018, still incipient in areas affected by mining (Callisto & Esteves 1998, Dedieu et al 2015, and nonexistent in the Amazonian campo rupestre ("rocky grassland"), the savanna vegetation growing on iron-rich laterite, known locally as the canga. This type of vegetation is embedded within a tropical forest matrix, generally in isolated tracts, and as it has a distinct soil composition and unique vegetation, the resident species need to adapt to these conditions to survive (Borges et al 2017).…”

Effects of Local Environmental and Landscape Variables on the Taxonomic and Trophic Composition of Aquatic Insects in a Rare Forest Formation of the Brazilian Amazon

et al. 2020

In the present study, we analyzed a unique phytophysiognomy in the Amazon region, which is formed by savanna-like vegetation on iron-rich soil (known locally as canga) located within an iron-ore mining region. We used the habitat template theory to test the hypothesis that changes in the physical-chemical properties of streams and the physical structure of their habitats at in-stream and micro-basin (landscape) levels affect the taxonomic and trophic composition of immature aquatic insects. For this, we used a local environmental matrix composed of nine physical-chemical and structural habitat variables, together with the Habitat Integrity Index. We also calculated landscape metrics based on the area of the microbasin, such as relief, slope, mean current flow, and vegetation cover. We divided the aquatic insects into five functional feeding groups based on their diet and food sources. Our results indicate that changes in the trophic level of the insects of the orders Ephemeroptera, Plecoptera, and Trichoptera are more easily observed than the taxonomic structure of communities. The loss of environmental integrity and vegetation cover were responsible for 84% of the variation observed in the composition of functional feeding groups (FFGs). Our study shows that aquatic insect communities in the canga and in the Amazon regions dominated by forest require specific in-stream and landscape conditions. These findings reinforce the need for the preservation of areas of canga vegetation, which not only have a unique levels of biological diversity, but are also targeted for the exploitation of their economically valuable natural resources.

“…Macroinvertebrate benthic community is commonly used as streams bioindicators. They are quite sensitive in responding to streams physical and chemical changes, have a variety of higher taxa, limited mobility, long life cycle, easy to sample, and easy to identified [8][9][10][11][12][13]. Distribution and abundance of macroinvertebrate benthic are driven by several factors such as habitat characteristic, water quality, pollutant, stream beds sediment characters, and biological factors including predators and competition [14].…”

Macroinvertebrate benthic community as rapid quality assessment in Winongo, Code, and Gajahwong Streams inside Yogyakarta City, Special Region of Yogyakarta Province

et al. 2019

Streams in Yogyakarta City are classified as an urban river, they receive huge amount of organic matter daily from anthropogenic waste. Growing urbanization affected water ecosystem causing water quality and benthic community changes. Macroinvertebrate benthic immediately respond to physic-chemical changes of the stream. Aims of this study are studying urbanization alter macroinvertebrate benthic community, and water quality in Winongo, Gajahwong, and Code streams of Yogyakarta City. Samples were collected at December 2015 and January 2017 in Winongo, Gajahwong, and Code streams inside the administration area of Yogyakarta City using sediment Dredge. Collections perform by dividing each stream into three parts with five replications. Macroinvertebrate benthic were filtered using stratified filter mesh 60, 40, and 20 results showed that macroinvertebrate benthic diversity decreasing from 2015 to 2017 in these three urban streams. There were not much species founded in Yogyakarta City Streams, indicates riparian ecosystem lack of natural habitat. All riparian zone are damage by anthropogenic activities. Their density is also decreasing probably because riparian floodplain embankment caused water velocity faster, leave little sediment for benthic organism. Chironomids larvae dominate in all stations in each river, and the most abundant in Code. They were abundant because streams in Yogyakarta City accept high input of organic matter. They classified as tolerate groups where their abundance indicates water pollution. High waterfall during 2016 most probably caused water quality better in 2017 than 2015. Dissolved oxygen was higher, and water ph is closer to neutral. Thus it cannot be used as an indicator.

1. Environmental changes are increasingly frequent, resulting in adverse impacts on biodiversity. These effects are more harmful when superimposed on areas of high biodiversity such as the Amazon region, in which the gaps in knowledge of the number of existing species and how they are distributed. This article reviews the known geographical distributions of Ephemeroptera in theBrazilian Amazon based on the current uneven sampling effort to identify which species and biodiversity hotspots are poorly protected, and where more work is required to address the conservation needs of this group.3. A sampling effort index was created to identify which areas have the highest potential mayfly richness and the greatest concentration of knowledge gaps. The mayfly records were combined with environmental variables to generate predictive models of the areas suitable for mayflies using species distribution modelling, and species that lack protection in conservation units and indigenous territories were indicated as priorities for future inventories. Caenis pflugfelderi, Microphlebia surinamensis, Tricorythopsis pseudogibbus and Tricorythodes sp. nov.were identified as threatened in the Brazilian Amazon given that they were recorded in an unprotected area of intense land use with a restricted potential distribution.4. Mayflies have been recorded in only 5% of the Brazilian Amazon biome. The model indicated a greater diversity in the northern and north-eastern Amazon.The sampling effort index indicated a total area of 46,225 km 2 in mayfly biodiversity not protected by conservation units or indigenous territories.5. This study raises awareness of the importance of intensifying studies of Ephemeroptera in the Brazilian Amazon, and demonstrates that the conservation units or indigenous territories do not protect many species.
