Abstract The European Water Framework Directive requires the determination of ecological status in fresh and saline waters. This is to be through establishment a typology surface water bodies, reference (high status) conditions each element (ecotype) lower grades (good, moderate, poor bad) for ecotype. It then classification bodies their restoration at least ‘good status’ specified period. Though there are many methods assessing quality, none has scope that defined Directive. provisions...
Summary 1. Results are analysed from 11 experiments in which effects of fish addition and nutrient loading on shallow lakes were studied mesocosms. The experiments, five 1998, six 1999, carried out lakes, distributed Finland to southern Spain, according a standard protocol. 2. Effects the treatments 29 chemical, phytoplankton zooplankton variables examined assess relative importance bottom‐up (nutrient enrichment) top‐down (fish predation) effects. For each year, different locations treated...
The atmospheric contribution constitutes about 90 percent of the signal measured by satellite sensors over oceanic and inland waters. Over open ocean waters, is relatively easy to correct as it can be assumed that water-leaving radiance in near-infrared (NIR) equal zero performed applying a simple dark-pixel-correction-based type algorithm. coastal this assumption cannot made since NIR greater than due presence water components like sediments dissolved organic particles. aim study determine...
Summary 1. Nutrient and fish manipulations in mesocosms were carried out on food‐web interactions a Mediterranean shallow lake south‐east Spain. Nutrients controlled biomass of phytoplankton periphyton, while zooplankton, regulated by planktivorous fish, influenced the relative percentages dominant species. 2. Phytoplankton species diversity decreased with increasing nutrient concentration density. Cyanobacteria grew well both turbid clear‐water states. 3. Planktivorous increased...
Summary 1. In view of the paucity data on response warm shallow lakes to reductions in nutrient loading, this paper presents a long‐term limnological set document changes food‐web Mediterranean lake (Lake Albufera, Valencia, Spain) that has experienced phosphorus (P) (77%) and nitrogen (N) (24%) loading following sewage diversion. 2. Nine years after diversion, P concentration was reduced by 30% but remained high (TP = 0.34 mg L −1 ), although mean water retention time only 0.1 years....
Precambrian Banded Iron Formation (BIF) deposition was conventionally attributed to the precipitation of iron-oxides resulting from abiotic reaction ferrous iron (Fe(II)) with photosynthetically-produced oxygen. Earliest traces oxygen date 2.7 Ga, thus raising questions as what may have caused BIF before oxygenic photosynthesis evolved. The discovery anoxygenic phototrophic bacteria thriving through oxidation Fe(II) has provided support for a biological origin some BIFs, but despite reports...
Sentinel-2 offers great potential for monitoring water quality in inland and coastal waters. However, atmospheric correction these waters is challenging, there no standardized approach yet, but different methods coexist under constant development. The Case 2 Regional Coast Colour (C2RCC) processor has been recently updated with the C2X-COMPLEX (C2XC). This study one of first attempts at exploring its performance, comparison C2RCC C2X, east Iberian Peninsula, retrieving surface reflectance...
Lakes represent a considerable natural source of methane to the atmosphere compared their small global surface area. Methanotrophs in sediments and water column largely control fluxes from these systems, yet diversity, electron accepting capacity nutrient requirements microorganisms have only been partially identified. Here we investigated role acceptors alternative oxygen sulfate microbial oxidation at oxycline anoxic waters ferruginous meromictic Lake La Cruz, Spain. Active turnover zone...
Freshwater quality maintenance is essential for human use and ecological functions. To ensure this objective, governments establish programs a continuous monitoring of the inland waters state. This could be possible with Sentinel-2 (S2) Sentinel-3 (S3), two remote sensing satellites European Space Agency, equipped spectral optical sensors. determine optimal water algorithms applicable to their bands, 36 were tested different key variables (chlorophyll (Chl_a), colored dissolved organic...
Abstract The European Water Framework Directive implements the policies to achieve a good ecological status of all waterbodies. To determine potential in freshwater environments, abiotic (morphology, physical and chemical variables) biotics (algae, fishes, etc.) metrics are used. Despite their importance trophic web, zooplankton was not included as one Biological Quality Elements (BQE) water quality. In present research, we studied species that can be considered indicators for more than 60...

Long-standing taxonomic problems involving the Acanthocyclops robustus–vernalis complex of freshwater cyclopoids have not been resolved. After Kiefer's designation A. robustus Sars as an older synonym Acanthocycops americanus Marsh, a lot data indicating their differentiation accumulated. To handle this taxonomical problem, representative populations from type localities respective taxa and other European US sites were analyzed morphologically genetically using mitochondrial COI 12S rRNA....

Summary 1. Shallow lake ecosystems are normally dominated by submerged and emergent plants. Biological stabilising mechanisms help preserve this dominance. The systems may switch to dominance phytoplankton, however, with loss of This process usually takes place against a background increasing nutrient loadings but also requires additional mechanisms, which damage the plants or interfere their mechanisms. 2. extent details even major features general model change geographical location not...
