Open AccessCoinfection frequency in water flea populations is a mere reflection of parasite diversity
In nature, parasite species often coinfect the same host. Yet, it is not clear what drives the natural dynamics of coinfection prevalence. The prevalence of coinfections might be affected by interactions among...

Open AccessPotential for high toxicity of polystyrene nanoplastics to the European Daphnia longispina
Current regulatory discussions about microplastics are often questioned based on a lack of data indicating high ecotoxic hazards of these particles within standard and recognized definitions. Moreover, there i...

Open AccessHost-Associated Bacterial Communities Vary Between Daphnia galeata Genotypes but Not by Host Genetic Distance
Host genotype may shape host-associated bacterial communities (commonly referred to as microbiomes). We sought to determine (a) whether bacterial communities vary among host genotypes in the water flea Daphnia ga...

Open AccessPrior exposure of a fungal parasite to cyanobacterial extracts does not impair infection of its Daphnia host
Cyanobacteria periodically dominate phytoplankton composition in lakes, and produce a wide array of toxic secondary metabolites. Blooms of cyanobacteria often coincide with infections of zooplankton by micropa...

Using DNA from formaldehyde-preserved Daphnia to reconstruct past populations
We compared taxon composition of the Daphnia longispina hybrid community, as reconstructed from dormant eggs (retrieved from sediment samples) and the pelagic population (retrieved from formaldehyde-preserved zoo...

Open AccessDaphnia galeata responds to the exposure to an ichthyosporean gut parasite by down-regulation of immunity and lipid metabolism
Regulatory circuits of infection in the emerging experimental model system, water flea Daphnia and their microparasites, remain largely unknown. Here we provide the first molecular insights into the response of D...

Open AccessCytonuclear diversity and shared mitochondrial haplotypes among Daphnia galeata populations separated by seven thousand kilometres
The zooplanktonic cladocerans Daphnia, present in a wide range of water bodies, are an important component of freshwater ecosystems. In contrast to their high dispersal capacity through diapausing eggs carried by...

Open AccessChytrid parasitism facilitates trophic transfer between bloom-forming cyanobacteria and zooplankton (Daphnia)
Parasites are rarely included in food web studies, although they can strongly alter trophic interactions. In aquatic ecosystems, poorly grazed cyanobacteria often dominate phytoplankton communities, leading to...

Toxicity of two fungicides in Daphnia: is it always temperature-dependent?
The joint effect of increasing temperature and pollution on aquatic organisms is important to understand and predict, as a combination of stressors might be more noxious when compared to their individual effec...

Open AccessGenetic diversity of two Daphnia-infecting microsporidian parasites, based on sequence variation in the internal transcribed spacer region
Microsporidia are spore-forming obligate intracellular parasites that include both emerging pathogens and economically important disease agents. However, little is known about the genetic diversity of microspo...

Outcome of esophageal atresia/tracheoesophageal fistula in extremely low birth weight neonates (<1000 grams)
To review the outcomes of extremely low birth weight (ELBW, <1000 g) infants with esophageal atresia/tracheoesophageal fistula (EA/TEF).

Open AccessPopulation structure of a microparasite infecting Daphnia: spatio-temporal dynamics
Detailed knowledge of spatial and temporal variation in the genetic population structure of hosts and parasites is required for understanding of host − parasite coevolution. As hot-spots of contemporary coevol...

Open AccessHybridizing Daphnia communities from ten neighbouring lakes: spatio-temporal dynamics, local processes, gene flow and invasiveness
In natural communities of cyclical parthenogens, rapid response to environmental change is enabled by switching between two reproduction modes. While long periods of asexual reproduction allow some clones to o...

Two threats at once: encounters with predator cues alter host life-history and morphological responses to parasite spores
Parasites and predators are ubiquitous threats in every ecosystem. Host and prey species, respectively, have evolved effective protective mechanisms which are assumed to involve costs. In this study, we analyz...

Open AccessFighting parasites and predators: How to deal with multiple threats?
Although inducible defences have been studied extensively, only little is known about how the presence of parasites might interfere with these anti-predator adaptations. Both parasites and predators are import...

Open AccessFine-scale temporal and spatial variation of taxon and clonal structure in the Daphnia longispinahybrid complex in heterogeneous environments
Cyclical parthenogenetic water fleas of the genus Daphnia have become a prominent model organism in ecology and evolution. In the past, analyses of their population structure have been limited by the prevailing u...

Epidemiology of a Daphnia brood parasite and its implications on host life-history traits
Parasites influence host life-history traits and therefore might crucially shape host populations in natural systems. In a series of laboratory experiments, we studied the impact of an oomycete brood parasite ...

Hatching with the enemy: Daphnia diapausing eggs hatch in the presence of fish kairomones
Infochemicals are known to play a key role in mediating predator-prey interactions, both in aquatic and terrestrial communities. However, state-dependent variation may exist in how effectively individuals can ...
