“…Poole and Berman (2001) consider activity related to the production of electric energy as a factor of importance to changes in water temperature. This finding is confirmed among others in reference to rivers in NW Spain (Álvarez-Troncoso et al 2015), or in the case of research conducted in the Rhone River in the Alps (Fette et al 2007). In Poland, coastal rivers (except for mountain rivers) can be considered as belonging to the most favourable locations for water power plants, as determined by their natural characteristics.…”

Abstract. The paper presents water temperature fluctuations in coastal rivers (Rega, Parsęta, Słupia, Łupawa, Łeba) located in the southern Baltic Sea area in Poland. Based on the available detailed data on daily values of the analysed characteristic in the years 1971-2015, tendencies of changes in the period were determined. It includes an analysis of temperature fluctuations in reference to mean annual and mean monthly values. In all of the five cases, the mean annual temperature showed an increasing tendency. The value of water warming in particular rivers was approximate, and ranged from 0.26 °C•dec -1 to 0.31°C•dec -1. At the monthly scale, the highest increase was recorded in April, and amounted to 0.46°C•dec -1 on average. Water temperature fluctuations were particularly determined by climatic changes, and strongly correlated with air temperature. Local factors characteristic for coastal rivers, i.e. presence of infrastructure of small water power plants and predominance of groundwater alimentation, had a secondary effect on changes in the thermal regime of the analysed rivers.Long-term water temperature fluctuations in coastal rivers (southern Baltic) in Poland

“…Various aquatic macroinvertebrates, such as mayflies, stoneflies and caddisflies (Ephemeroptera, Plecoptera and Trichoptera) are commonly used as bio-indicator organisms for water quality and ecosystem assessments 4–6 . This is down to their rapid reaction to anthropogenic change such as levels of pollution, climate change, fracking, mining, and the construction of hydroelectric stations for example 5,7–9 .…”

21Isogenus nubecula is a critically endangered Plecoptera species. Considered extinct in the UK, the 22 species was recently rediscovered in one location of the river Dee in Wales after 22 years of absence. As 23 many species belonging to the Perlodidae, this species can be a bio-indicator, utilised for assessing 24 water quality and health status of a given freshwater system. However, conventional monitoring of 25 invertebrates via kick-sampling for example, is an invasive and expensive (time consuming). Further, 26 such methods require a high level of taxonomic expertise. Here, we compared the traditional kick-27 sampling method with the use of eDNA detection using qPCR and ddPCR-analyses. In spring 2018, we 28 sampled eDNA from twelve locations on the river Dee. I. nubecula was detected using kick-sampling in 29 five of these locations, three locations using both eDNA detection and kick-sampling and one location 30 using eDNA detection alone -resulting in a total of six known and distinct populations of this critically 31 endangered species. Interestingly, despite the eDNA assay being validated in vitro and in silico, and 32 results indicating high sensitivity, qPCR analysis of the eDNA samples proved to be ineffective. In 33 contrast, ddPCR analyses resulted in a clear detection of I. nubecula at four locations suggesting that 34 inhibition most likely explains the big discrepancy between the obtained qPCR and ddPCR results. It is 35 therefore important to explore inhibition effects on any new eDNA assay. We also highlight that ddPCR 36 may well be the best option for the detection of aquatic organisms which are either rare or likely to shed 37 low levels of eDNA into their environment. 38

“…Three aquatic insect orders, the mayflies (Ephemeroptera), stoneflies (Plecoptera) and caddisflies (Trichoptera), also known as EPT, are often used as biological indicators in freshwater quality assessments (Baird & Sweeney, ; Hering et al., ; Illies & Schmitz, ; Kolkwitz & Marsson, ; Liebmann, ; Meier et al., ; Pantle & Buck, ; Rolauffs, Hering, Sommerhäuser, Jähnig, & Rödiger, ; Sweeney, Battle, Jackson, & Dapkey, ; Zhou et al., ) and ecological studies (Böhmer, Rawer‐Jost, & Zenker, ; Böhmer et al., ; Braukmann & Biss, ; Lorenz, Hering, Feld, & Rolauffs, ; Schmedtje & Colling, ; Schöll, Haybach, & König, ; Vannote, Minshall, Cummins, Sedell, & Cushing, ). Bioindicator species are often used to survey the health of ecosystems, as they exhibit strong responses to pollution, mining, fracking or climate change (Álvarez‐Troncoso, Benetti, Sarr, Pérez‐Bilbao, & Garrido, ; Burton et al., ; Dedieu, Rhone, Vigouroux, & Céréghino, ; Wallace, Grubaugh, & Whiles, ; Wiederholm, ; Zhou et al., ). Therefore, an unambiguous identification of EPT species is a crucial step for investigations of freshwater quality, ecology and possible change or loss of biodiversity (Macher et al., ).…”

Mayflies, stoneflies and caddisflies (Ephemeroptera, Plecoptera and Trichoptera) are prominent representatives of aquatic macroinvertebrates, commonly used as indicator organisms for water quality and ecosystem assessments. However, unambiguous morphological identification of EPT species, especially their immature life stages, is a challenging, yet fundamental task. A comprehensive DNA barcode library based upon taxonomically well-curated specimens is needed to overcome the problematic identification. Once available, this library will support the implementation of fast, cost-efficient and reliable DNA-based identifications and assessments of ecological status. This study represents a major step towards a DNA barcode reference library as it covers for two-thirds of Germany's EPT species including 2,613 individuals belonging to 363 identified species. As such, it provides coverage for 38 of 44 families (86%) and practically all major bioindicator species. DNA barcode compliant sequences (≥500 bp) were recovered from 98.74% of the analysed specimens. Whereas most species (325, i.e., 89.53%) were unambiguously assigned to a single Barcode Index Number (BIN) by its COI sequence, 38 species (18 Ephemeroptera, nine Plecoptera and 11 Trichoptera) were assigned to a total of 89 BINs. Most of these additional BINs formed nearest neighbour clusters, reflecting the discrimination of geographical subclades of a currently recognized species. BIN sharing was uncommon, involving only two species pairs of Ephemeroptera. Interestingly, both maximum pairwise and nearest neighbour distances were substantially higher for Ephemeroptera compared to Plecoptera and Trichoptera, possibly indicating older speciation events, stronger positive selection or faster rate of molecular evolution.
