“…Despite the efficiency of the functional groups approach, it is still a challenge in tropical regions, in particular in regions, such as the Amazon basin, for which the available database is limited (Brito et al 2018). At the present time, in fact, most of the field data and classifications have been derived from biodiversity studies in the temperate zone (Brasil et al 2020a). Given the increasing number of studies evaluating functional diversity in tropical macroinvertebrates (Luiza-Andrade et al 2017b), however, it is hoped that the database will expand further, in general, and, in particular, provide insights into the functionality of tropical streams, rather than just on their functional feeding groups.…”

“…The flow velocity (m/s) was estimated three times by timing the movement of an object floating over a distance of 3 m. The mean value was obtained per stream for all the metrics (Table 1). The selection of these variables was based on previous studies, which showed that they are ecologically relevant to the EPT (Brasil et al 2020a).…”

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.

“…These classification scores based on the HII have already been successfully used in other studies in the Amazon region [42]. Additionally, in a recent review, it was shown that the index is very efficient in studies of environmental monitoring using aquatic insects [43].…”

Response of the Zygopteran Community (Odonata: Insecta) to Change in Environmental Integrity Driven by Urbanization in Eastern Amazonian Streams

The accelerated and disordered growth of large urban centers has caused a significant loss of biodiversity and the negative effects are more significant in aquatic environments. Thus, the objective of this study is to assess the effects of environmental change due to urbanization in the abundance and biomass patterns of species belonging to the Zygoptera suborder. We tested the hypothesis that, in altered streams, there will be a predominance of organisms with fast growth and small biomass (r-strategists), and intermediate streams will have an overlapping of r and k-strategists. In control streams, there will be a predominance of k-strategists, with slow growth, decreased abundance, and high biomass. Urban expansion in Amazonian streams will cause loss of Zygoptera species richness. Streams draining urban areas will have higher air temperatures than control streams. Thus, small-sized and less abundant species will be favored. We sampled 15 streams in the metropolitan area of Belém. Sites were classified, using the index of physical habitat integrity, as control, intermediate and altered. Comparisons between biomass and abundance were analyzed using W Statistics. Our analyses showed that: the effects of urbanization cause loss of k-strategists and favors r-strategists, once abundance was placed above biomass; in intermediate environments, contrary to what we expected, there was no overlapping of strategies, once r-strategists were also placed above k-strategists; in control environments, biomass was placed above abundance, suggesting these environments have a predominance of k-strategist species, as we suggested; and we observed increased levels of temperature favor the most abundant species, the ones having generalist biological mechanisms; however, contrary to what we expected, there was no difference in richness. With these results, we reinforce the need for public policies to create or maintain the riparian forest along streams running through urban areas and create or maintain urban parks.

“…We measured 12 limnological environmental variables and landscape metrics that are considered important in assessing the level of environmental impact and in predicting Heteroptera and Odonada assemblages (Brasil et al, 2020b;Giehl et al, 2020): (1) air temperature, (2) nitrate, (3) ammonia, (4) turbidity, (5) water temperature, (6) dissolved oxygen (OD), (7) potential hydrogen (pH), (8) electric conductivity, (9) total dissolved solids (TDS), (10) oxidation-reduction potential (ORP), (11) luminosity, and (12) landscape change (Supplementary Table S1). To measure the chemical variables, we sampled 500 ml of water from each vereda in polyethylene bottles.…”

Dams Change Beta Diversity of Aquatic Communities in the Veredas of the Brazilian Cerrado

The veredas are wetland ecosystems responsible for supplying most of the water for rivers and streams in the Cerrado. The veredas’ hydromorfic soils retain a large amount of rainwater, releasing it slowly during drier periods. Therefore, these habitats are often used to build dams for cattle raising. Here we assessed the environmental conditions and beta-diversity of Odonata and Heteroptera on veredas impacted by dams in the Brazilian Cerrado. We sampled biological communities and a set of environmental variables in 13 veredas, six with dams and seven without dams. One limnological variable [oxidation–reduction potential (ORP)] and one landscape metric (% of the altered area) differed among veredas with and without dams. These variables were important predictors of the beta-diversity of both Odonata (R2 = 0.650; p < 0.001) and Heteroptera (R2 = 0.740; p < 0.001). The veredas stand among the most sensitive wetland ecosystems of the Cerrado. In this study, we show, for the first time, that veredas with dams may lose environmental quality resulting in changes in biological communities, especially ecologically unique species. Because the Cerrado naturally goes through approximately 5 months of severe drought, the veredas are critical for the Cerrado’s hydric safety. Therefore, we recommend that cattle-raising activities should rely on artificial water tanks instead of using dams for water storage since it affects ecologically unique species in this poorly known ecosystem.
