Heterocyst-infecting chytrid parasites reduce nitrogen fixation and host growth under nitrogen-limiting conditions in the cyanobacterium <i>Dolichospermum sp</i> Open
Chytrids infect and kill various phytoplankton. Studies of chytrids infecting cyanobacteria and microalgae have focused only on a few host–parasite systems (hosts mainly Planktothrix and Asterionella). Here we focus on a newly isolated and…

CoFish: co-designing citizen science between fishers and scientists to monitor the phosphorus distribution across two Lake Geneva basins Open
Background Eutrophication, followed by re-oligotrophication during lake restoration, in many peri-alpine lakes has caused important changes to the functioning and biodiversity of freshwater ecosystems. In Lake Geneva, total phosphorus (TP)…

What Does It Mean to Be(Come) Arctic? Functional and Genetic Traits of Arctic‐ and Temperate‐Adapted Diatoms Open
Climate change‐induced warming is expected to drive phytoplankton poleward as they track suitable thermal conditions. However, successful establishment in new environments requires adaptation to multiple abiotic factors beyond temperature …

Temperature, resources and predation interact to shape phytoplankton size–abundance relationships at a continental scale Open
Aim Communities contain more individuals of small species and fewer individuals of large species. According to the ‘metabolic theory of ecology’, the relationship of log mean abundance with log mean body size across communities should exhi…

The emergence and dominance of <i>Planktothrix rubescens</i> as an hypolimnetic cyanobacterium in response to re‐oligotrophication of a deep peri‐alpine lake Open
Toxic cyanobacteria, such as Planktothrix rubescens , came to dominate temperate lakes in the mid‐to‐late 20 th century, as a result of eutrophication. Even after decades of re‐oligotrophication, where phosphorus levels were reduced by 1–2…

Are we underestimating the ecological and evolutionary effects of warming? Interactions with other environmental drivers may increase species vulnerability to high temperatures Open
Warming, the most prominent aspect of global environmental change, already affects most ecosystems on Earth. In recent years, biologists have increasingly integrated the effects of warming into their models by capturing how temperature sha…
