Abstract Freshwater ecosystems worldwide are threatened by salinisation caused human activities. Scientific attention on the ecological impacts of from road deicing salts is increasing exponentially. Spanning multiple trophic levels and ecosystem types, we review synthesise salt in freshwater to understand species‐, community‐, ecosystem‐level responses. In our review, identify knowledge gaps that hope will motivate future research directions. We found negatively affect species at all levels, biofilms fish. The concentration which triggered an effect varied considerably. Species‐level were generally sub‐lethal, leading reductions growth reproduction, can be magnified natural stressors such as predation. Community‐level including biodiversity common, communities salt‐tolerant species, may have implications for disease transmission enhanced recruitment host mosquitoes. At level, alter nutrient energy flow. Contaminated wetlands could see greater export greenhouse gases, streams probably more nitrogen carbon, lakes encounter altered hydrology oxygen dynamics, phosphorus release sediments. While it necessary keep roads safe humans, costs severe if actions not taken mitigate salinisation.

Freshwater salinisation: a research agenda for a saltier world

Trends in Ecology & Evolution, Год журнала: 2022, Номер 37(5), С. 440 - 453

Опубликована: Янв. 18, 2022

The widespread salinisation of freshwater ecosystems poses a major threat to the biodiversity, functioning, and services that they provide. Human activities promote through multiple drivers (e.g., agriculture, resource extraction, urbanisation) are amplified by climate change. Due its complexity, we still far from fully understanding ecological evolutionary consequences salinisation. Here, assess current research gaps present agenda guide future studies. We identified different in taxonomic groups, levels biological organisation, geographic regions. suggest focusing on global- landscape-scale processes, functional approaches, genetic molecular levels, eco-evolutionary dynamics as key avenues predict for human societies.

Review: Toward management of urban ponds for freshwater biodiversity

Abstract Many cities around the world are expanding and this trend in urbanization is expected to sharply increase over coming decades. At same time, integration of green blue spaces widely promoted urban development, potentially offering numerous benefits for biodiversity. This particularly relevant waterbodies, a type ecosystem present most cities. However, site managers often lack knowledge base promote biodiversity these which generally created provide other services. To address this, our review presents guidelines promoting ponds. We found total 516 publications indexed ISI Web Sciences related topic, 279 were retained purposes review. The ponds, measured by species richness, appears be lower than rural ponds; however, ponds support threatened species. Furthermore, if well managed, have potential much greater they currently do. Indeed, shows that range factors can impair or pond biodiversity, including many easily controlled managers. Local include design (surface area, depth, banks margins, shade, shoreline irregularity), water quality (conductivity, nutrients, heavy metals), hydroperiod biotic characteristics (stands vegetation, fish, invasive species). Important regional several indicators (roads, buildings, density population, impervious surfaces, car traffic), presence wetlands surrounding landscape. considered each their impact on freshwater Taking into account management measures listed reviewed, we proposed framework with services, avoid disservices creation ecological traps. city scale, pondscape from high diversity types, differing environmental management.

Current water quality guidelines across North America and Europe do not protect lakes from salinization

Proceedings of the National Academy of Sciences, Год журнала: 2022, Номер 119(9)

Опубликована: Фев. 22, 2022

Significance The salinity of freshwater ecosystems is increasing worldwide. Given that most organisms have no recent evolutionary history with high salinity, we expect them to a low tolerance elevated caused by road deicing salts, agricultural practices, mining operations, and climate change. Leveraging the results from network experiments conducted across North America Europe, showed salt pollution triggers massive loss important zooplankton taxa, which led increased phytoplankton biomass at many study sites. We conclude current water quality guidelines established governments in Europe do not adequately protect lake food webs, indicating an immediate need establish where they exist reassess existing guidelines.

A review of recent advances and future challenges in freshwater salinizationIn spite being a worldwide phenomenon that can have important ecological, economic social consequences, salinization (i.e. the increase ion concentrations freshwaters) has been poorly studied when compared with other environmental issues.However, it is receiving increasing attention, significant scientific made during last two decades.Here I current knowledge on topic propose research directions within context human welfare global change.Freshwater caused by wide range activities, agriculture resource extraction most widely documented.Different studies suggest could be affecting around 1/3 bodies, this number will very likely due to climate land use changes.The salinity freshwaters known cause adverse effects fitness survival many aquatic organisms, however osmoregulatory mechanisms underlying these are still understood.Moreover, proved different ions toxicities but focused exclusively Na + Cl -.Thus, more investigations potential specific (e.g.K , SO 4 2-) needed.The impact biodiversity alter ecosystem functioning, although only few functions (e.g.leaf litter decomposition).Also, affect delivery services direct (e.g.infrastructure corrosion) (e.g.human health) impacts rarely assessed.The management urgent issue needs improved through mitigation (e.g.backfilling mine tailings), remediation (e.g.enhanced wastewater treatment), prevention (e.g. using alternative deicers for roads) monitoring (e.g.estimating salt loads ecosystems) actions.

Salinity impacts on river ecosystem processes: a critical mini-review

Philosophical Transactions of the Royal Society B Biological Sciences, Год журнала: 2018, Номер 374(1764), С. 20180010 - 20180010

In many dry parts of the world, salinization water resources threatens freshwater biodiversity and livelihood people. However, ecological impact studies remain scarce. Here, we review field-observations salinity impacts on ecosystem processes such as leaf decomposition, metabolism, biomass production nutrient cycling, with a special emphasis dryland ecosystems. addition, discuss potential linkages these to service delivery—the benefits that humans derive from ecosystems—as additional nature conservation arguments challenges associated this endeavour. This article is part theme issue ‘Salt in freshwaters: causes, consequences future prospects'.

Lakes in the Midwest and Northeast United States are at risk of anthropogenic chloride contamination, but there is little knowledge prevalence spatial distribution freshwater salinization. Here, we use a quantile regression forest (QRF) to leverage information from 2773 lakes predict concentration all 49 432 greater than 4 ha 17-state area. The QRF incorporated 22 predictor variables, which included lake morphometry characteristics, watershed land use, distance nearest road interstate. Model predictions had an r2 0.94 for observations, 0.86 median observed each lake. four predictors with largest influence on concentrations were low medium intensity development watershed, crop density Almost 2000 predicted have above 50 mg L–1 should be monitored. We encourage management governing agencies lake-specific model assess salt contamination as well augment their monitoring strategies more comprehensively protect ecosystems

Rivers are experiencing increasing anthropogenic pressures and salinity has shown to affect freshwater fish behaviour, potentially disrupting ecological processes. In this study, the aim was determine sub-lethal effects of salinization on using a widespread native cyprinid species, Iberian barbel (Luciobarbus bocagei) as model species. Behavioural trials in mesocosms setting were performed assess three levels gradient - control (no salt added water, 0.8 mS/cm), low (9 high concentration (18 mS/cm) routine activity, shoal cohesion boldness.
