<title>Abstract</title> Saline lakes are hypersensitive to changes in their water balance and therefore show amplified responses climatic land-use catchment. However, despite the resulting, often dramatic ecological consequences, saline rank low on policy agendas as they assumed support few ecosystem services levels of biodiversity. Here, we challenge this view evaluate threatened species 84 distributed across globe. We found that harbour not only aquatic biota but also a diverse range...
Measuring reliable greenhouse gases (GHGs) fluxes at the interface between water bodies and atmosphere in inland waters is crucial context of climate change but remains highly challenging. &#160;GHG can be measured directly in-situ with chambers placed water-atmosphere connected to portable gas analysers providing high-frequency timeseries GHGs partial pressures inside chamber. Fluxes are usually assumed constant over time incubation, varying GHG sources changing environmental conditions...
Inland saline shallow lakes play a role in the carbon and greenhouse gases exchange with atmosphere their climate regulation capacity is highly influenced by ecological status management. Our aim was to evaluate, through numerical modelling, behaviour of representative lakes, influence lake management on metabolic rates balance under different scenarios. The possible effects actions were modelled relation water regime vegetation cover, showing importance temporary flooding pattern key...
Wetlands are among the most biologically active ecosystems on Earth, playing an important role in global carbon cycle. Methane production wetlands, resulting from anaerobic respiration of organic matter, accounts for part natural sources methane. In this work, we have evaluated methane release rates saline shallow lakes located Central Spain, some which maintain conditions, whereas others hydrologically altered, with lowered salinity, or even presenting trophic alterations. We used sediment...
Deltaic wetlands are highly productive ecosystems, which characteristically can act as C-sinks. However, they among the most threatened being very vulnerable to global change, and require special attention towards its conservation. Knowing their climate change mitigating potential, conservation measures should also be oriented with a climatic approach, strengthen regulatory services. In this work we studied carbon biogeochemistry specific relevance of certain microbial guilds on metabolisms...
This work aims to validate the wide use of an algorithm developed using genetic programing (GP) techniques allowing discern between water and non-water pixels near infrared band different thresholds. A total 34 wetlands shallow lakes 18 ecological types were used for validation. These include marshes, salt ponds, saline freshwater, temporary permanent lakes. Furthermore, based on spectral matching Landsat Sentinel-2 sensors, this methodology was applied imagery, improving spatial temporal...
The effluents from conventional wastewater treatment plants (WWTP), even if accomplishing quality regulations, substantially differ in their characteristics with those of waters natural environments. Constructed wetlands (CWs) serve as transitional ecosystems within WWTPs, mitigating these differences and restoring features before water is poured into the environment. Our study focused on an experimental surface-flow CW naturalizing WWTP effluent a semiarid area Eastern Spain. Despite...
Permanent freshwater and brackish marshes are the typical wetland type of Mediterranean Spanish coast. Historically, alterations to original morphological hydrological characteristics some these ecosystems have increased their trophic status, which could influence carbon (C) balance, while other remain close natural condition. In this work, main processes related C cycle were studied in several coastal with different degrees alteration sites restored managed ways. Carbon associated...

The features of lentic waterbodies largely depend on the surrounding environment. Mediterranean coastal lagoons have been historically altered, with their catchment being highly modified for agricultural, livestock, or urban uses. Changes in land uses induce pressures that impact and alter ecological status. objectives this paper were: to develop a methodological approach (LUPLES: Land Uses estimating Pressure Levels Ecological Status), quantify main forecast possible impacts these...
Physical and chemical alterations may affect the microbiota of soils as much specific presence toxic pollutants. The relationship between microbial diversity patterns soil quality in a Mediterranean context is studied here to test hypothesis that strongly affected by level anthropogenic alteration. Our aim has been determine potential effect organic matter loss associated changes poorly evolved (Leptosols Regosols) suffering stress (i.e., cropping deforestation). correspond nine different...
Constructed wetlands are commonly used for sewage treatment. However, as the natural processes operate, these artificial ecosystems can also be to enhance equalization of water features those receiving environments, thus reducing impacts treated on systems. Here, we studied, by a year-round survey, simultaneous and separated operation two subsurface that were tertiary treatment naturalization wastewaters had already been in waste plant (WWTP). These operating serially, with first wetland...
Abstract Understanding the metabolic processes governing carbon biogeochemistry in inland brackish and saline shallow lakes is crucial for assessing their capacity to mitigate climate change. This study aimed investigate relationship between biotic processes, balances, environmental factors such as salinity, hydroperiod, ecological status, which can be affected by human activities. We analysed rates budgets 19 sites Spanish Mediterranean region, representing diverse conditions. Results...
Abstract Karstic lakes on gypsum are a very peculiar type of ecosystem declared as Habitat Type Community Interest (Type 3190) by the European Habitats Directive. They usually small but often displaying high relative depth, located in active karst areas, with saturation Ca 2 + and SO 4 2− its waters. These can stratify from spring to early autumn when depth is enough, then sulphide-rich anoxic hypolimnion develop deep layers. So far, neither comprehensive scientific definition their...
Mediterranean inland saline lakes may play an important role in the carbon cycle due to metabolic capacities of their prokaryotic communities.However, these are not homogeneous and have different environmental characteristics.In this work, structure function communities inhabiting water sediments 15 shallow been studied.These grouped categories according salinity, conservation statuses alterations, which determine structuration carbon-related metabolisms.Each salinity category status showed...
Saline shallow lakes may play an important role in carbon exchange with the atmosphere, but their alteration change balance and greenhouse gas emissions patterns. This study investigated relationship between metabolic processes environmental factors, focusing on alterations salinity, hydroperiod length, trophic status. The results revealed that disruptions to natural salinity patterns, driven by hydrological changes ecological degradation, enhanced emitting metabolisms. In contrast,...

The monitoring of the structure and potential function prokaryotic assemblages aquatic ecosystems can be used for assessment ecosystem health. In this work, we analysed by 16S rRNA gene amplicon massive sequencing sediment communities inhabiting three wetlands located in Ebro river Delta (Spain), which differ their salinity trophic status. We extracted DNA from both matrices sequenced V4 region Illumina sequencing. raw sequences obtained were processed clustered ZOTUs, are at 100% identity...
The use of proxies for ecosystem function in biomonitoring is desirable to move towards more holistic strategies. Next-generation sequencing environmental DNA can clearly contribute these advances. This research part a project aimed constructed wetlands (CWs), managed by the company Global Omnium (https://www.globalomnium.com/Group/Home/) and having University Valencia charge scientific research, order improve ecological quality already treated wastewaters before being poured into natural...
