Abstract Despite the ecological and societal importance of large rivers, fish sampling remains costly limited to specific habitats (e.g., river banks). Using an eDNA metabarcoding approach, we regularly sampled 500 km a (Rhône River). Comparisons with long-term electrofishing surveys demonstrated ability qualitatively quantitatively reveal assemblage structures (relative species abundance) but integrated larger space than classical location. Combination literature review field data showed...
Owing to a long history of anthropogenic pressures, freshwater ecosystems are among the most vulnerable biodiversity loss
Abstract Understanding and predicting how biological communities respond to climate change is critical for assessing biodiversity vulnerability guiding conservation efforts. Glacier‐ snow‐fed rivers are one of the most sensitive ecosystems change, can provide early warning wider‐scale changes. These frequently used hydropower production but there minimal understanding influenced by in a context flow regulation. This study sheds light on this issue disentangling structural (water temperature...
Abstract Most of the present EU Water Framework Directive (WFD) compliant fish‐based assessment methods European rivers are multi‐metric indices computed from traditional electrofishing (TEF) samples, but this method has known shortcomings, especially in large rivers. The probability detecting rare species remains limited, which can alter sensitivity indices. In recent years, environmental (e)DNA metabarcoding techniques have progressed sufficiently to allow applications various ecological...
Globalization has led to the introduction of thousands alien species worldwide. With growing impacts by invasive species, understanding invasion process remains critical for predicting adverse effects and informing efficient management. Theoretically, dynamics have been assumed follow an "invasion curve" (S-shaped curve available area invaded over time), but this dynamic lacked empirical testing using large-scale data neglects consider invader abundances. We propose "impact describing...
Abstract As alien invasive species are a key driver of biodiversity loss, understanding patterns rapidly changing global compositions depends upon knowledge population dynamics and trends at large scales. Within this context, the Ponto-Caspian region is among most notable donor regions for aquatic in Europe. Using macroinvertebrate time series collected over 52 years (1968–2020) 265 sites across 11 central western European countries, we examined occurrences, invasion rates, abundances...
The zebra mussel Dreissena polymorpha is one of the most successful, notorious, and detrimental aquatic invasive non‐native species worldwide, having invaded Europe North America while causing substantial ecological socio‐economic impacts. Here, we investigated spatiotemporal trends in this species' invasion success using 178 macroinvertebrate abundance time series, containing 1451 records D. collected across nine European countries between 1972–2019. Using these raw (absolute) data,...
Abstract Setting appropriate conservation strategies in a multi-threat world is challenging goal, especially because of natural complexity and budget limitations that prevent effective management all ecosystems. Safeguarding the most threatened ecosystems requires accurate integrative quantification their vulnerability functioning, particularly potential loss species trait diversity which imperils functioning. However, magnitude threats associated biological responses both have high...
Abstract Aim Invasive alien species are a growing problem worldwide due to their ecological, economic and human health impacts. The “killer shrimp” Dikerogammarus villosus is notorious invasive amphipod from the Ponto‐Caspian region that has invaded many fresh brackish waters across Europe. Understandings of large‐scale population dynamics highly impactful invaders such as D. lacking, inhibiting predictions impact efficient timing management strategies. Hence, our aim was assess trends well...
Abstract Ongoing global changes are causing major ecological shifts worldwide. Biological trends need to be assessed over long periods of time better understand past and current community responses. The present study developed a methodological framework for meta‐analyses conducted that account the temporal spatial autocorrelation observational data. We provided R code processing this framework, which enables tested through analysis long‐term, spatially structured datasets. Taking both types...
Abstract Aquatic ecosystem recovery from anthropogenic degradation can be hampered by internal feedbacks that stabilize undesirable states. The challenges of managing and predicting alternative states in lakes are well known, but state shifts rivers their attendant effects on function remain understudied despite strong recent evidence such do occur. Using three decades measurements key variables as turbidity, nutrient concentrations, Corbicula fluminea clam densities, chlorophyll a ,...
Abstract. Stream temperature appears to be increasing globally, but its rate remains poorly constrained due a paucity of long-term data and difficulty in parsing effects hydroclimate landscape variability. Here, we address these issues using the physically based thermal model T-NET (Temperature-NETwork) coupled with EROS semi-distributed hydrological reconstruct past daily stream streamflow at scale entire Loire River basin France (105 km2 52 278 reaches). increased for almost all reaches...
Climate-induced changes in river conditions, such as water temperature and current velocity, can disrupt species migration patterns by altering the conditions encountered during migration. We assessed these impacts across Loire River basin Europe compiling long-term fish passage data for three diadromous at fishways, alongside reconstructed time series of velocity. considered both velocity on days when was observed ''suitable conditions'' species' upstream Our findings 1963–2019 period...
Coastal ecosystems are affected by numerous direct anthropogenic pressures (urbanization, fisheries, etc.) and global changes (climate change, biological invasions, etc.). Long-term monitoring of their biodiversity is crucial for (1) diagnosing disturbances as early possible, (2) evaluating conservation (Marine Protected Areas) restoration actions, (3) better predicting the dynamics functioning. However, national international programs often limited in time (1-4 years) offer few...
Abstract Freshwater macroinvertebrates are a diverse group and play key ecological roles, including accelerating nutrient cycling, filtering water, controlling primary producers, providing food for predators. Their differences in tolerances short generation times manifest rapid community responses to change. Macroinvertebrate composition is an indicator of water quality. In Europe, efforts improve quality following environmental legislation, primarily starting the 1980s, may have driven...
Most key life-events of organisms are synchronized by complex interactions several environmental cues to ensure optimal survival and growth individuals their offspring. However, global change is known affect multiple components ecosystems at the same time. Therefore, detecting joint trends in covariate time series a crucial challenge ecology that has rarely been addressed so far. In this context, we designed an innovative combination kernel density estimations Mann-Kendall trend tests detect...
Functionally distinct species (i.e. with unique trait combinations in the community) can support important ecological roles and contribute disproportionately to ecosystem functioning. Yet, how functionally have responded recent climate change human exploitation has been widely overlooked. Here, using traits long-term fish data North Sea, we identified common species, evaluated their spatial temporal dynamics relation environmental variables fishing pressure. were characterized by late sexual...
Hydropeaking corresponds to rapid artificial discharge variations, designed address sub-daily peaks in electricity demand. It generates changes physical habitat (e.g., flow velocity and water depth) with potential impacts on stream assemblages. For assessing the generality of hydropeaking effects fish assemblages, we present an original combination spatial (among 45 reaches, including six groups nearby reaches) temporal (over 3-17 years) analyses these effects. Our involved descriptions...
Species distribution models (SDMs) are the main tool to predict global change impacts on species ranges. Climate alone is frequently considered, but in freshwater ecosystems, hydrology a key driver of ecology aquatic species. At large scale, however rarely accounted for, owing lack detailed stream flow data. In this study, we developed an integrated modelling approach simulate using hydrological Soil and Water Assessment Tool (SWAT). Simulated was subsequently included as input variable SDMs...
