Drivers of macroinvertebrate assemblages in littoral and pelagic habitats of a large shallow lake: implications for bioassessment
Different measures of macroinvertebrate diversity (species diversity, functional diversity, phylogenetic diversity) and functional feeding groups (FFGs) are commonly used to assess the ecological status of lar...

Open AccessTime series of freshwater macroinvertebrate abundances and site characteristics of European streams and rivers
Freshwater macroinvertebrates are a diverse group and play key ecological roles, including accelerating nutrient cycling, filtering water, controlling primary producers, and providing food for predators. Their...

Multi-decadal improvements in the ecological quality of European rivers are not consistently reflected in biodiversity metrics
Humans impact terrestrial, marine and freshwater ecosystems, yet many broad-scale studies have found no systematic, negative biodiversity changes (for example, decreasing abundance or taxon richness). Here we ...

Open AccessAcidification of freshwater lakes in Scandinavia: impacts and recovery of chironomid communities under accelerating environmental changes
We re-examined the effects of acidification on Scandinavian freshwater lakes using paleolimnological reconstructions focused on subfossil chironomids. Our study showed a widespread shift in chironomid communit...

Open AccessThe recovery of European freshwater biodiversity has come to a halt
Owing to a long history of anthropogenic pressures, freshwater ecosystems are among the most vulnerable to biodiversity loss1. Mitigation measures, including wastewater treatment and hydromorphological restoratio...

Open AccessChallenges in supplying empirical proof for predictions derived from Species Distribution Models (SDMs): the case of an invasive cyanobacterium
Species distribution models (SDMs) calibrated with bioclimatic variables revealed a high probability for range expansion of the invasive toxin producing cyanobacterium, Raphidiopsis raciborskii to Sweden, where n...

Open AccessPartitioning spatial, environmental, and community drivers of ecosystem functioning
Community composition, environmental variation, and spatial structuring can influence ecosystem functioning, and ecosystem service delivery. While the role of space in regulating ecosystem functioning is well ...

Approaches for integrated assessment of ecological and eutrophication status of surface waters in Nordic Countries
We review approaches and tools currently used in Nordic countries (Denmark, Finland, Norway and Sweden) for integrated assessment of ‘ecological status’ sensu the EU Water Framework Directive as well as assess...

Spatial Patterns and Functional Redundancies in a Changing Boreal Lake Landscape
Global transformations extend beyond local habitats; therefore, larger-scale approaches are needed to assess community-level responses and resilience to unfolding environmental changes. Using long-term data (1...

Linking degradation status with ecosystem vulnerability to environmental change
Environmental change can cause regime shifts in ecosystems, potentially threatening ecosystem services. It is unclear if the degradation status of ecosystems correlates with their vulnerability to environmenta...

Open AccessThe Swedish monitoring of surface waters: 50 years of adaptive monitoring
For more than 50 years, scientific insights from surface water monitoring have supported Swedish evidence-based environmental management. Efforts to understand and control eutrophication in the 1960s led to co...

Cross-taxon responses to elevated nutrients in European streams and lakes
Few studies have compared the response of different taxonomic groups to environmental stress across aquatic ecosystems. We regressed assemblage structure of fish, invertebrates, macrophytes, phytoplankton and...

The impact of climate on the geographical distribution of phytoplankton species in boreal lakes
Here, we use a novel space-by-time approach to study large-scale changes in phytoplankton species distribution in Swedish boreal lakes in response to climate variability. Using phytoplankton samples from 27 la...

In situ generated cellulose nanoparticles to enhance the hydrophobicity of paper
Handsheets with in situ generated cellulose nanoparticles were made from oxidized pulp fibers prepared by 2,2,6,6-tetramethylpiperidinyl-1-oxyl-mediated oxidation of kraft fiber with sodium hypochlorite and so...

Community structure in boreal lakes with recurring blooms of the nuisance flagellate Gonyostomum semen
Blooms of the nontoxic raphidophyte Gonyostomum semen have shown a recent increase in frequency and distribution in the Fennoscandian region. Due to large cell size and several grazer-avoidance strategies, G. sem...

Optimizing stream bioassessment: habitat, season, and the impacts of land use on benthic macroinvertebrates
Bioassessment of running waters should ideally be optimized to include sampling of the biota when and where they are most sensitive to anthropogenic disturbances, but direct comparisons of the responses of bio...

Preparation and characterization of hydrophobic derivatives of TEMPO-oxidized nanocelluloses
Amidation and ionic complexation were evaluated as surface modification treatments for TEMPO-oxidized nanocelluloses (TONc), using octadecylamine (ODA) as the modifying compound. Effects of the two treatments ...

Effects of nutrient enrichment on C and N stable isotope ratios of invertebrates, fish and their food resources in boreal streams
Carbon and nitrogen stable isotopes are frequently used to study energy sources and food web structure in ecosystems, and more recently, to study the effects of anthropogenic stress on aquatic ecosystems. We i...
