Open Access“Candidatus Intestinibacterium parameciiphilum”—member of the “Candidatus Paracaedibacteraceae” family (Alphaproteobacteria, Holosporales) inhabiting the ciliated protist Paramecium
Protists frequently host diverse bacterial symbionts, in particular those affiliated with the order Holosporales (Alphaproteobacteria). All characterised members of this bacterial lineage have been retrieved in o...

Antimicrobial Resistance in Used Water Treatment and Water Reuse
Antibiotic resistance is one of the most pressing global health threats of our time. The rise of antibiotic-resistant bacteria is largely attributed to the overuse and misuse of antibiotics in human medicine, ...

Open AccessReduced selection for antibiotic resistance in community context is maintained despite pressure by additional antibiotics
Selection for antibiotic resistance at very low antibiotic concentrations has been demonstrated for individual antibiotics in single species experiments. Furthermore, selection in these focal strains is reduce...

Open AccessActive movement to coarse grained sediments by globally endangered freshwater pearl mussels (Margaritifera margaritifera)
The freshwater pearl mussel Margaritifera margaritifera is an endangered bivalve which is usually regarded as sedentary, although individual movement has been observed both vertically and horizontally. Little is ...

Open AccessThey do not fear the unknown: Ancylus fluviatilis (Mollusca, Planorbidae) shows no predator avoidance behavior towards a novel invasive predator
Biological invasion is a strong threat to native biodiversity, with limnic systems being especially vulnerable due to historical separation and resulting prey naivety. The prey naivety hypothesis states that n...

Open AccessDeciphering chloramphenicol biotransformation mechanisms and microbial interactions via integrated multi-omics and cultivation-dependent approaches
As a widely used broad-spectrum antibiotic, chloramphenicol is prone to be released into environments, thus resulting in the disturbance of ecosystem stability as well as the emergence of antibiotic resistance...

Article
Open AccessEnsemble of models shows coherent response of a reservoir’s stratification and ice cover to climate warming
Water temperature, ice cover, and lake stratification are important physical properties of lakes and reservoirs that control mixing as well as bio-geo-chemical processes and thus influence the water quality. W...

Open AccessA genome-wide scan of wastewater E. coli for genes under positive selection: focusing on mechanisms of antibiotic resistance
Antibiotic resistance is a global health threat and consequently, there is a need to understand the mechanisms driving its emergence. Here, we hypothesize that genes and mutations under positive selection may ...

Open AccessManaging climate change in drinking water reservoirs: potentials and limitations of dynamic withdrawal strategies
Climate change induced a rise in surface water temperature and a prolongation of summer stratification in drinking water reservoirs. Stratification and temperature are important factors for drinking water prod...

Managing Water Resources for Urban Catchments
The overall objective of the project was the development of water management system solutions for a sustainable improvement of water quality in the city of Chaohu and in the Chao Lake. The Urban Water Resource...

WP-C: A Step Towards Secured Drinking Water: Development of an Early Warning System for Lakes
Lakes are important ecosystems that provide a number of ecosystem services including provision of drinking water, flood control, fisheries and in general a high natural, cultural and aesthetic value. Provision...

Open AccessHigh genomic diversity of multi-drug resistant wastewater Escherichia coli
Wastewater treatment plants play an important role in the emergence of antibiotic resistance. They provide a hot spot for exchange of resistance within and between species. Here, we analyse and quantify the ge...

Article
Extended Spectrum Beta-Lactamase (ESBL)-producing bacteria isolated from hospital wastewaters, rivers and aquaculture sources in Nigeria
Untreated wastewater is a risk factor for the spread of antibiotic resistance in the environment. However, little is known about the contribution of untreated wastewater to the burden of antibiotic resistance ...

New Paramecium (Ciliophora, Oligohymenophorea) congeners shape our view on its biodiversity
Paramecium is one of the best known and most intensely studied ciliate genera. It currently comprises 18 morphospecies including the P. aurelia complex of 15 sibling species. Here, we describe th...

Tackling antibiotic resistance: the environmental framework
Antibiotic resistance constitutes a threat to human and animal health worldwide. Here, Manaia and colleagues report the main findings of the European COST (Cooperation in Science and Technology) Action DARE (D...

Article
Fish predation can induce mesohabitat-specific differences in food web structures in small stream ecosystems
Diverse benthic communities in streams include a wide variety of predators with different habitat preferences, e.g. for pools or riffles. We hypothesised that these preferences result in mesohabitat-specific p...

Environmental and public health implications of antibiotic-resistance genes in municipal wastewaters
Antibiotic resistance is a serious threat to public health in Europe leading to increasing health-care costs and deaths. Combating antibiotic resistance requires an understanding of the ecology of antibiotic-r...

Open AccessRediscovering the genus Lyticum, multiflagellated symbionts of the order Rickettsiales
Among the bacterial symbionts harbored by the model organism Paramecium, many still lack a recent investigation that includes a molecular characterization. The genus Lyticum consists of two species of large-sized...

Open AccessConvergent evolution of heat-inducibility during subfunctionalization of the Hsp70 gene family
Heat-shock proteins of the 70 kDa family (Hsp70s) are essential chaperones required for key cellular functions. In eukaryotes, four subfamilies can be distinguished according to their function and localisation...
