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...
Biotic interactions are fundamental drivers governing biodiversity locally, yet their effects on geographical variation in community composition (i.e. incidence‐based) and structure abundance‐based) at regional scales remain controversial. Ecologists have only recently started to integrate different types of biotic into assembly a spatial context, theme that merits further empirical quantification. Here, we applied partial correlation networks infer the strength dependencies between pairs...
ABSTRACT Biodiversity studies have usually been conducted considering only the taxonomic dimension of ecological communities. However, diversity measurements taking into account functional traits species may be more sensitive in capturing aspects community functioning that are not apparent with traditional approach. Functional (either based on alpha or beta levels) is, therefore, a facet provides link between ecosystem and structure an important metric for assessing impact global change...
Abstract Motivation Aquatic insects comprise 64% of freshwater animal diversity and are widely used as bioindicators to assess water quality impairment ecosystem health, well test ecological hypotheses. Despite their importance, a comprehensive, global database aquatic insect occurrences for mapping biodiversity in macroecological studies applied research is missing. We aim fill this gap present the Global EPTO Database , which includes worldwide geo‐referenced occurrence records four major...
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...
1. The EC Water Framework Directive requires that Member States assess the ecological quality of their water bodies on basis a wide set variables, including benthic invertebrates. 2. aim study was to find one or more faunistic indices could be related status shallow lakes, independent different macrophyte types. 3. Six invertebrate were calculated from abundance and biomass data in 10 Spanish lakes: total biomass, Shannon's index, percentage predators, Ephemeroptera, Plecoptera Trichoptera,...
Summary 1. The impacts of nutrients (phosphorus and nitrogen) planktivorous fish on phytoplankton composition biomass were studied in six shallow, macrophyte‐dominated lakes across Europe using mesocosm experiments. 2. Phytoplankton was more influenced by than densities fish. Nutrient addition resulted increased algal at all locations. In some experiments, a decrease noted the highest nutrient loadings, corresponding to added concentrations 1 mg L −1 P 10 N. 3. Chlorophyll precise parameter...
Recent researches have started to provide useful information on the littoral macroinvertebrates living in European mountain ponds. However, there is still uncertainty factors really shaping their communities. Understanding patterns of biodiversity these systems essential for conservation and management purposes. In this paper, we sampled at 51 ponds from a wide Spanish region (Castilla y León) order define which set environmental variables were responsible differences richness (genus level...
Abstract Aim Metacommunity ecology is a vibrant area of research that has received increased attention in recent years, since it provides framework to assess the underlying dispersal‐ and niche‐based processes create non‐random ecologically meaningful patterns species assemblages across landscape. Here we set out test for role dispersal limitation, sorting shared effects assembly pond macrophyte metacommunities an extensive within Iberian Plateau, identify which traits, environmental...
Summary 1. A 2‐year study was carried out on the roles of nutrients and fish in determining plankton communities a shallow lake north‐west Spain. Outcomes were different each year depending initial conditions, especially macrophyte biomass. In 1998 estimated ‘per cent water volume inhabited’ (PVI) by submerged macrophytes about 35%. Phytoplankton biomass as chlorophyll strongly controlled fish, whereas effects nutrient enrichment not significant. 1999 PVI 80%, no effect observed...
To detect when changes in response to stressors are occurring, biomonitoring programs require an understanding of shifts biota that occur anthropogenic and natural effects. Aquatic plants expected reflect the environmental conditions ponds and, according European Water Framework Directive, macrophytes should be considered ecological status assessments inland surface waters. We assessed relative importance impacts on submerged, emergent floating-leaved 44 Duero river basin (North Iberian...
