Published: March 5, 2024

Abstract Rising water temperatures in rivers due to climate change are already having observable impacts on river ecosystems. Warming has both direct and indirect aquatic life, further aggravates pervasive issues such as eutrophication, pollution, the spread of disease. Animals can survive higher through physiological and/or genetic acclimation, behavioral phenological change, range shifts more suitable locations. As such, those animals that adapted cool‐water regions typically found high altitudes latitudes where there fewer dispersal opportunities most at risk future extinction. However, sub‐lethal animal physiology phenology, body‐size, trophic interactions could have significant population‐level effects elsewhere. Rivers vulnerable warming because historic management left them exposed solar radiation removal riparian shade, hydrologically disconnected longitudinally, laterally, vertically. The resilience riverine ecosystems is also limited by anthropogenic simplification habitats, with implications for resource use resident organisms.

Combined effects of heatwaves and micropollutants on freshwater ecosystems: Towards an integrated assessment of extreme events in multiple stressors research

Abstract Freshwater ecosystems are strongly influenced by weather extremes such as heatwaves (HWs), which predicted to increase in frequency and magnitude the future. In addition these climate extremes, freshwater realm is impacted exposure various classes of chemicals emitted anthropogenic activities. Currently, there limited knowledge on how combined HWs affects structure functioning ecosystems. Here, we review available literature describing single effects different levels biological organization, obtain a holistic view their potential interactive effects. We only found few studies (13 out 61 included this review) that investigated combination with chemical pollution. The reported varied largely not within trophic but also depending studied endpoints for populations or individuals. Hence, owing little number available, no consistent could be highlighted at any level organization. Moreover, an imbalance towards species population experiments, five using multitrophic approach.

Interactive Effects of Warming and Pollutants on Marine and Freshwater Invertebrates

Abstract Purpose of Review Global warming and pollution are among the five major causes global biodiversity loss, particularly in aquatic invertebrates which highly diverse but understudied. In this review, we highlight advancements current environmental studies investigating interactive effects between contaminants freshwater marine invertebrates. We not only focused on temperate regions also synthesized information less studied Arctic/Antarctic tropical regions. Recent Findings general, same combination may result either additive or non-additive depending taxa, response variable, life stage, genotype, exposure level, duration order exposure, number exposed generations. For traditional such as metals pesticides, combined with at individual level were generally synergistic. Growing evidence suggests that multigenerational can shift interaction toward antagonism, while contemporary evolution change type. Summary Our synthesis highlights importance temporal aspects shaping type, including ontogenetic effects, transgenerational evolution. The laboratory experiments (to advance mechanistic understanding) outdoor mesocosm field observations increase realism) is needed to obtain comprehensive assessments pollutants from genes ecosystems.

Influence of climate change and pesticide use practices on the ecological risks of pesticides in a protected Mediterranean wetland: A Bayesian network approach

Pollution by agricultural pesticides is one of the most important pressures affecting Mediterranean coastal wetlands. Pesticide risks are expected to be influenced climate change, which will result in an increase temperatures and a decrease annual precipitation. On other hand, pesticide dosages change given pest resistance implementation environmental policies like European ´Farm-to-Fork` strategy, aims for 50 % reduction usage 2030.

Combined stress of an insecticide and heatwaves or elevated temperature induce community and food web effects in a Mediterranean freshwater ecosystem

Water Research, Journal Year: 2024, Volume and Issue: 260, P. 121903 - 121903

Published: June 6, 2024

Ongoing global climate change will shift nature towards Anthropocene's unprecedented conditions by increasing average temperatures and the frequency severity of extreme events, such as heatwaves. While climatic changes pose an increased threat for freshwater ecosystems, other stressors like pesticides may interact with warming lead to unpredictable effects. Studies that examine underpinned mechanisms multiple stressor effects are scarce often lack environmental realism. Here, we conducted a experiment using outdoor mesocosms natural assemblages macroinvertebrates, zooplankton, phytoplankton, macrophytes, microbes. The neonicotinoid insecticide imidacloprid (1 µg/L) were investigated in combination three temperature scenarios representing ambient, elevated (+4°C), heatwaves (+0 8°C), latter two having similar energy input. We found dissipation patterns all treatments lowest half-lives under both (DT50: 3 days) highest ambient 4 throughout experiment. Amongst communities, only zooplankton community was significantly affected combined treatments. This demonstrated low chemical sensitivity lagged significant negative cyclopoids. Heatwaves caused early long-lasting on compared temperatures, Polyarthra, Daphnia longispina, Lecanidae, cyclopoids being most negatively taxa, whereas Ceriodaphnia nauplii showed positive responses temperature. Community recovery from stress slower heatwaves, suggesting temperature-enhanced toxicity. Finally, microbial macrofauna litter degradation enhanced temperature, also imidacloprid. A structural equation model depicted cascading food web stronger relationships at higher than lower trophic levels. Our study highlights series imidacloprid-stressed freshwaters.

An Emergency Recovery Plan (ERP) proposed 2020 comprises six measures intended “bend curve” loss, if they are widely adopted adequately supported. We review evidence suggesting that combined intensity persistent emerging threats become so serious current projected efforts preserve, protect restore inland‐water ecosystems may insufficient avert losses coming decades. In particular, climate change, complex harmful impacts, will frustrate attempts prevent from already affected by multiple threats. Interactions among these limit recovery populations exacerbate declines resulting local or even global extinctions, especially low‐viability degraded fragmented ecosystems. addition impediments represented we identify several other areas where absolute scarcity fresh water, inadequate information predictive capacity, a failure mitigate anthropogenic stressors, liable set limits on biodiversity.
