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

The Science of The Total Environment, Journal Year: 2023, Volume and Issue: 878, P. 163018 - 163018

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. The influence use practices on ecological needs evaluated making realistic scenarios. This study investigates how different affect Albufera Natural Park (Valencia, Spain), protected wetland.

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.

Abstract This study investigates the distribution and conservation status of plant species in lentic wetlands Mediterranean islands. Field data on vascular macrophytes were collected from online national databases “Conservation island Basin” (MedIsWet). A comprehensive inventory was conducted, information main anthropogenic impacts priorities compiled. In addition to all hygro- hydrophytes, we retained those typically adapted environments with intermittent or temporary wetness. significant knowledge gap regarding found. lower endemism rate observed particularly coastal wetlands. However, approximately 25% species, mainly relatively wide distribution, identified as endangered unknown status. Including seasonal wetness is crucial when considering wetland efforts. The research emphasised importance diverse types, including permanent, natural artificial, for effective conservation. Artificial emerged potential habitats considerable biodiversity value. provides a valuable insights into ecology, relevance aquatic enhances our understanding biogeographic patterns processes, offers critical management wetlands, presents replicable approach that can be applied other contexts.
