Open AccessLife in a changing environment: dreissenids’ feeding response to different temperature
Invasive species have far-reaching consequences for whole ecosystems. The two dreissenids zebra and quagga mussels are two of the most successful invaders in aquatic systems. Quagga mussels can colonize deeper...

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...

Geographical and temporal patterns of cyanobacterial assemblages in the Danube Delta lake complexes
Danube Delta shallow lakes experience cyanobacteria blooms that can negatively affect the aquatic ecosystem. Although there are several studies on Danube Delta cyanobacteria, little is known about their spatia...

Sex in crowded places: population density regulates reproductive strategy
Changing reproductive strategy from investment in current (asexual eggs) to future (sexual ephippia) reproduction depending on environmental cues is an important fitness trait in zooplankton species like water...

Diversity and distribution of Daphnia across space and time in Danube Delta lakes explained by food quality and abundance
Eutrophication of shallow lakes often triggers a series of cascading ecological effects. Among these are shifts in the zooplankton community structure due to phytoplankton changes, or shifts in the fish commun...

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...

Consumer-resource dynamics is an eco-evolutionary process in a natural plankton community
When traits affecting species interactions evolve rapidly, ecological dynamics can be altered while they occur. These eco-evolutionary dynamics have been documented repeatedly in laboratory and mesocosm experi...

Open AccessHigh dispersal levels and lake warming are emergent drivers of cyanobacterial community assembly in peri-Alpine lakes
Disentangling the relative importance of deterministic and stochastic processes in sha** natural communities is central to ecology. Studies about community assembly over broad temporal and spatial scales in ...

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...

Homogenization of lake cyanobacterial communities over a century of climate change and eutrophication
Human impacts on biodiversity are well recognized, but uncertainties remain regarding patterns of diversity change at different spatial and temporal scales. Changes in microbial assemblages are, in particular,...

Sedimentary and egg-bank DNA from 3 European lakes reveal concurrent changes in the composition and diversity of cyanobacterial and Daphnia communities
Eutrophication generally favours the growth of cyanobacteria over eukaryotic green algae in freshwater lakes. Cyanobacteria constitute a poor food source for the waterflea Daphnia, an important primary consumer o...

Clonal structure and depth selection during a Caullerya mesnili epidemic in a hybridizing population of the Daphnia longispina complex
Daphnia perform diel vertical migration (DVM), a predator-avoidance strategy to migrate towards deeper and colder layers in the water column in the morning and movement to the algae-rich ...

Parasite Fitness Traits Under Environmental Variation: Disentangling the Roles of a Chytrid’s Immediate Host and External Environment
Parasite environments are heterogeneous at different levels. The first level of variability is the host itself. The second level represents the external environment for the hosts, to which parasites may be exp...

At the edge and on the top: molecular identification and ecology of Daphnia dentifera and D. longispina in high-altitude Asian lakes
The occurrence of members of the highly diverse Daphnia longispina complex in Southern and Central Asian high-mountain lakes has been recognized for more than a century. Until now, however, no molecular data have...

Combined exposure to parasite and pesticide causes increased mortality in the water flea Daphnia
Organisms are exposed to multiple biotic and abiotic environmental stressors, which can influence the dynamics of individual populations and communities. Populations may also genetically adapt to both natural ...

Starving with a full gut? Effect of suspended particles on the fitness of Daphnia hyalina
Suspended particles are abiotic factors that can affect the abundance of cladocerans such as daphnids. Ultra-oligotrophic Lake Brienz, situated in the front ranges of the Swiss Alps, is dominated by two major ...
