“…It is comprised of a transition zone between Mixed Ombrophilous Forest and Semideciduous Seasonal Forest, two distinct Atlantic Forest physiognomies ( Joly et al 1999 ). There are 761 angiosperms, about 250 of them being arboreal species ( ICMBio 2018 ) and 84 mammal species, including some endangered ones, such as the jaguar, puma and tapir ( Brocardo et al 2019 ). The INP’s terrestrial fauna is also estimated to comprise more than 550 birds, 635 butterflies, 79 reptiles and 55 amphibians ( WWF-Brazil 2014 ) and for aquatic fauna, 18 species of stream fish ( Delariva et al 2018 ) and 193 taxa of benthic macroinvertebrates at hydrographic systems that flow to below the Waterfall ( Moretto and Pujarra 2017 ) are reported.…”

Background Iguaçu National Park (INP) is known worldwide due to Iguaçu Waterfalls, being considered a World Natural Heritage by UNESCO. The INP is one of the last large forested extensions of inland Brazil that provides protection to the Atlantic Forest, one of the world’s biodiversity hotspots. However, its Natural Heritage status has been threatened by the construction and operation of the Baixo Iguaçu dam, agricultural and urban impacts on its boundaries and the increasing interest of the Brazilian government in re-opening of the “Colono road”, an old illegal road that crossed the interior of the park. Indeed, since benthic macroinvertebrates have been widely used for the environmental assessment of streams, records and abundance of their taxa under different seasonal periods may provide an additional dataset for biomonitoring of hydrographic systems in the face of current anthropogenic impacts on the INP boundaries and other similar streams on forest edges. New information In this study, we improved the sampling design of benthic macroinvertebrates and provided seasonal records covering distinct precipitation/temperature periods between 2016 and 2017 of a stream on the eastern edge of the Iguaçu National Park, Brazil. The records total 2,840 individuals distributed in 88 different taxa. The most abundant taxa were the Diptera subfamilies, Chironominae (n = 1,487) and Tanypodinae (n = 256), besides the Heterelmis genus (n = 152, Elmidae; Coleoptera). Diptera was the richest order in number of families (n = 8), while Leptophlebiidae (Ephemeroptera) was the richest taxonomic family in number of genera (n = 11). Aegla (Crustacea) and the Insecta genera, Heterelmis, Hexacylloepus, Noelmis, Phylloicus and Thraulodes, were recorded through all samplings. Twenty-five genera of Ephemeroptera, Plecoptera, Trichoptera (EPT) and Odonata were recorded during intermediate precipitation/temperature periods. Twenty-one of them were recorded in May 2016, with five genera standing out in abundance (Hydrosmilodon, Anacroneuria, Argia, Coryphaeschna, Americabaetis) and four (Needhamella, Tikuna, Simothraulopsis, Neocordulia) in December 2016. Four general taxa were exclusive of the lower precipitation/temperature period (August 2016), standing out in abundance were the Oxystigma (Odonata) and Corydalus (Megaloptera) genera. In March 2017 (higher precipitation/temperature period), four exclusive taxa were recorded, amongst them, the Chimarra (Trichoptera) genus. Furthermore, seasonal records demonstrated higher occurrences and abundance of macroinvertebrates during the intermediate and lower precipitation/temperature periods, besides a varied taxa composition throughout the year, with the presence of both sensitive and tolerant groups to environmental impacts. Our findings suggest that the number and composition of the local-stream macrobenthic fauna were influenced by the seasonal climatic regime. These changes should be considered in the limnological monitoring developed on the hydrographic systems of INP eastern edges to improve the assessment of environmental quality under different local seasonal conditions.

“…Other mammals were only assigned at the family level, including other rodents (Cricetidae and Hydrocharidae), one bat (Phyllostomidae), and one carnivore (Procyonidae), that is a New World family (Duszynski et al, 2018). Although two species of Procyonidae, Nasua nasua and Procyon crancrivorous, are common in the region (Brocardo et al, 2019), these species were present in our reference database matching with a low similarity. These sequences may have low similarity due to the lack of publicly available representative sequences of the species which them belong, highlighting the need of further studies in the Neotropical region.…”

Metabarcoding of environmental DNA is based on primers that are specific to the target taxa (e.g. bacteria, zooplankton, fishes). However, due to the nature of the commonly used protocols, regardless of the chosen primers, several sequences of non-target species will inevitably be generated, but are usually discarded in commonly used bioinformatics pipelines. These non-target sequences might contain important biological information about the presence of other species in the studied habitats and its potential for ecological studies is still poorly understood. Here, we analyzed the presence of mammal and bird species in aquatic environmental samples that were originally amplified targeting teleost fish species. After all cleaning and checking steps, we kept 21 amplicon sequence variants (ASVs) belonging to mammals and ten to birds. Most ASVs were taxonomic assigned to farm/domestic animals, such as cats, cows, and ducks. Yet, we were able to identify a native semi-aquatic mammal, the capybara, in the samples. Four native bird species and a non-native potentially invasive bird (Corvus sp.) were also detected. Although the data derived from these samples for mammals and birds are of limited use for diversity analyses, our results demonstrate the potential of aquatic samples to characterize non-aquatic birds and highlight the presence of a potentially invasive species that had not been recorded before in the region.

“…Despite the importance of CUs for environment and biota conservation, many taxa are unknown, even in these sites of relevance for Brazil and the world ( e.g ., Sekiama et al 2001; Brocardo et al 2019). In addition, the degradation of riparian forests can contribute to habitat homogenization, making it difficult for the maintenance of aquatic communities, due in part to competition for reduced resources ( Fidelis et al 2008).…”
