1. Causes and consequences of Gonyostomum semen blooms
Abstract : Aquatic ecosystems provide essential ecosystem services, but are also highly vulnerable to global change. Climate change, eutrophication and browning, for example, collectively drive the increase of harmful algal blooms in freshwaters. READ MORE

2. Drivers and food web effects of Gonyostomum semen blooms
Abstract : The flagellate Gonyostomum semen forms dense late-summer blooms in humic lakes and is a nuisance to swimmers because it forms a slimy coat on the skin, causing irritation in sensitive individuals. Increasing occurrence and bloom incidence of G. READ MORE

3. Single-cell population genetics and dispersal limitation of a bloom-forming microalga
Abstract : Microalgal range expansions are increasing in frequency and magnitude worldwide mostly due to anthropogenic factors. However, they often remain unnoticed until mass development (algal blooms) occurs due to difficulties in detection when population densities are low. READ MORE

4. A Phytoplankton Invasion: Population Genetics, Phylogeography, and Invasion Success of Gonyostomum semen
Abstract : nvasive species is a major threat to ecosystems and biodiversity. Invasions by macroorganisms have been intensively studied, but little is known concerning microbial invasions. In aquatic environments, phytoplankton, i.e. READ MORE

5. Physical and biological dispersal barriers in invasive, bloom-forming microalgae
Abstract : For a long time microorganisms were assumed to have unlimited dispersal due to their small size and high cell numbers. Most microbial species can be transported by water currents, in water droplets by wind and attached to other organisms. READ MORE
