Unravelling large-scale patterns and drivers of biodiversity in dry rivers
Foulquier, Arnaud; Datry, Thibault; Corti, Roland; von Schiller, Daniel; Tockner, Klement; Stubbington, Rachel; more 86 authorsMore than half of the world’s rivers dry up periodically, but our understanding of the biological communities in dry riverbeds remains limited. Specifically, the roles of dispersal, environmental filtering and biotic interactions in driving biodiversity in dry rivers are poorly understood.Here, we conduct a large-scale coordinated survey of patterns and drivers of biodiversity in dry riverbeds. We focus on eigh...
Long-term trends in crayfish invasions across European rivers
Soto, Ismael; Ahmed, Danish A.; Beidas, Ayah; Oficialdegui, Francisco J.; Tricarico, Elena; Angeler, David G.; Amatulli, Giuseppe; Briski, ElizabetaEurope has experienced a substantial increase in non-indigenous crayfish species (NICS) since the mid-20th century due to their extensive use in fisheries, aquaculture and, more recently, pet trade. Despite relatively long invasion histories of some NICS and negative impacts on biodiversity and ecosystem functioning, large spatio-temporal analyses of their occurrences are lacking. Here, we used a large freshwat...
The recovery of European freshwater biodiversity has come to a halt
Haase, Peter; Bowler, Diana E.; Baker, Nathan J.; Bonada, Núria; Domisch, Sami; Garcia Marquez, Jaime R.; Heino, Jani; Hering, Daniel; Jähnig, Sonja C.Owing to a long history of anthropogenic pressures, freshwater ecosystems are among the most vulnerable to biodiversity loss1. Mitigation measures, including wastewater treatment and hydromorphological restoration, have aimed to improve environmental quality and foster the recovery of freshwater biodiversity2. Here, using 1,816 time series of freshwater invertebrate communities collected across 22 European coun...
Invasion impacts and dynamics of a European-wide introduced species
Haubrock, Phillip J.; Ahmed, Danish A.; Cuthbert, Ross N.; Stubbington, Rachel; Domisch, Sami; Marquez, Jaime R. G.; Beidas, Ayah; Amatulli, GiuseppeGlobalization has led to the introduction of thousands of alien species worldwide. With growing impacts by invasive species, understanding the invasion process remains critical for predicting adverse effects and informing efficient management. Theoretically, invasion dynamics have been assumed to follow an "invasion curve" (S-shaped curve of available area invaded over time), but this dynamic has lacked empiric...
Trends in flow intermittence for European rivers
Tramblay, Yves; Rutkowska, Agnieszka; Sauquet, Eric; Sefton, Catherine; Laaha, Gregor; Osuch, Marzena; Albuquerque, M.T.D.; Alves, Maria HelenaIntermittent rivers are prevalent in many countries across Europe, but little is known about the temporal evolution of intermittence and its relationship with climate variability. Trend analysis of the annual and seasonal number of zero-flow days, the of dry spells and the mean date of the zero-flow events is performed on a database of 452 rivers with varying degrees of intermittence between 1970 and 2010. The ...
River ecosystem conceptual models and non‐perennial rivers: A critical review
Allen, Daniel C.; Datry, Thibault; Boersma, Kate S.; Bogan, Michael T.; Boulton, Andrew J.; Bruno, Daniel; Busch, Michelle H.; Costigan, Katie H.Conceptual models underpin river ecosystem research. However, current models focus on continuously flowing rivers and few explicitly address characteristics such as flow cessation and drying. The applicability of existing conceptual models to nonperennial rivers that cease to flow (intermittent rivers and ephemeral streams, IRES) has not been evaluated. We reviewed 18 models, finding that they collectively desc...
Accounting for flow intermittency in environmental flows design
Acuña, Vicenç; Jorda‐Capdevila, Dídac; Vezza, Paolo; De Girolamo, Anna Maria; McClain, Michael E.; Stubbington, Rachel; Pastor, Amandine V.River ecosystems world‐wide are affected by altered flow regimes, and advanced science and practice of environmental flows have been developed to understand and reduce these impacts. But most environmental flows approaches ignore flow intermittency, which is a natural feature of 30% of the global river network length. Ignoring flow intermittency when setting environmental flows in naturally intermittent rivers ...
A global analysis of terrestrial plant litter dynamics in non-perennial waterways
Datry, Thibault; more 68 authors; Morais, Manuela55Perennial rivers and streams make a disproportionate contribution to global carbon (C) cycling. However, the contribution of intermittent rivers and ephemeral streams (IRES), which sometimes cease to flow and can dry completely, is largely ignored although they represent over half the global river network. Substantial amounts of terrestrial plant litter (TPL) accumulate in dry riverbeds and, upon rewetting, thi...
Biomonitoring of intermittent rivers and ephemeral streams in Europe: Current p...
Stubbington, Rachel; Chadd, Richard; Cid, Núria; Csabai, Zoltán; Miliša, Marko; Morais, Manuela; Munné, Antoni; Pařil, Petr; Pešić, VladimirIntermittent rivers and ephemeral streams (IRES) are common across Europe and dominate some Mediterranean river networks, supporting high biodiversity and providing ecosystem services in all climate zones. 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 'ecologi...
Science and Management of Intermittent Rivers and Ephemeral Streams (SMIRES)
Datry, Thibault; Singer, Gabriel; Sauquet, Eric; Jorda-Capdevilla, Didac; Von Schiller, Daniel; Subbington, Rachel; Magand, Claire; Pařil, PetrMore than half of the global river network is composed of intermittent rivers and ephemeral streams (IRES), which are expanding in response to climate change and increasing water demands. After years of obscurity, the science of IRES has bloomed recently and it is being recognised that IRES support a unique and high biodiversity, provide essential ecosystem services and are functionally part of river networks a...
