Biomonitoring of intermittent rivers and ephemeral streams in Europe: Current practice and priorities to enhance ecological status assessments

Abstract: Intermittent rivers and ephemeral streams (IRES) are common across Europe and dominate some Mediterranean river networks. In all climate zones, IRES support high biodiversity and provide ecosystem services. As dynamic ecosystems that transition between flowing, pool, and dry states, IRES are typically poorly represented in biomonitoring programmes implemented to characterize EU Water Framework Directive ecological status. We report the results of a survey completed by representatives from 20 European countries… Show more

“…Extreme low‐flow conditions (<20% of median annual flow) in managed streams simulated patterns extensively reported for intermittent streams (Datry et al., ; Stubbington et al., ), where habitats such as pools provide, to some extent, favourable conditions between flow releases. Andean streams with unmanaged conditions are known for their high levels of dissolved oxygen and low nutrient concentrations, providing suitable conditions for benthic fauna colonisation (Ríos‐Touma, Encalada, & Prat Fornells, ).…”

“…IRES likely make up at least 50% of the world's waterways (Datry et al 2014), and flow intermittency is further increasing in extent and duration in response to changes in climate and land use (Leigh et al 2016). Despite a continually growing body of research on IRES (Datry et al 2017), substantial knowledge gaps of flow intermittencyecosystem function relationships still exist (Leigh et al 2016, Stubbington et al 2018. In particular, little is known regarding the ecology of intermittent alpine streams, which can experience up to 90% intermittency in fluvial networks (Robinson et al 2016).…”

“…Collection of high-resolution data on flow intermittency is often time and labor intensive (Stubbington et al 2018). Further, gauging stations are most often placed on large, perennial channels, rather than the extensive upper network of low-order streams that are more likely to dry (Meyer et al 2007, Snelder et al 2013.…”

“…Furthermore, it also can be difficult to assess whether missing gauge data are due to surface‐water drying, malfunction and maintenance, or transition to a lentic state (Oueslati et al ; Stubbington et al ). Many other direct measures (field mapping, aerial photos, remote sensing, citizen science; Fritz et al , Gallart et al , Robinson et al , Spence and Mengistu ) and indirect indicators of intermittency (temperature, modeling, aquatic community structure; Constantz et al , Cid et al , González‐Ferreras and Barquín ) are used, often in combination, to identify the distribution of IRES at finer spatial resolution ( see Stubbington et al ). However, these are largely time, labor, and cost‐intensive for measuring fine‐scale temporal variation in flow intermittency, especially for whole river networks.…”
