Vampyrella crystallifera sp. nov., an Amoeba That Dissolves Entire Algal Cells at a Remarkable Speed [PDF]
The vampyrellid amoebae (Order Vampyrellida, Rhizaria) comprise predatory microeukaryotes that inhabit freshwater, marine, and terrestrial habitats. They are known to consume a wide array of prey, which includes microalgae, fungi, and even microscopic ...

The vampyrellid amoeba Strigomyxa ruptor gen. et sp. nov. and its remarkable strategy to acquire algal cell contents. [PDF]
The new vampyrellid amoeba Strigomyxa ruptor phagocytizes algal cells and opens them internally to extract the cell contents. Afterward, the algal cell walls are discarded through a “waste vacuole.” This sophisticated feeding strategy, here termed “internal protoplast extraction and cell wall regurgitation,” exemplifies the extraordinary complexity of ...

Biogeographical Distribution of River Microbial Communities in Atlantic Catchments. [PDF]
We discovered different factors affecting river microbial communities (RMC) diversity and composition across Atlantic catchments in Europe. Prokaryote diversity was mainly influenced by topography and geology, while eukaryotic groups were driven by land use and cover.

Temperature-dependent responses to light and nutrients in phytoplankton. [PDF]
Abstract Nutrients and light are major resources controlling growth, biomass, and community structure of phytoplankton. When looking at those resources individually, resource uptake and biochemical transformation, and thereby also the demand for resources, have been shown to be temperature‐dependent.

Chlorophytes response to habitat complexity and human disturbance in the catchment of small and shallow aquatic systems [PDF]
Human-originated transformation in the catchment area may be reflected in the water quality and ecological state of the aquatic environment. Chlorophytes, the most common and diverse group of microalgae, may be a valuable tool for studies of small water ...

Divergent responses in desiccation experiments in two ecophysiologically different Zygnematophyceae
Abstract Water scarcity can be considered a major stressor on land, with desiccation being its most extreme form. Land plants have found two different solutions to this challenge: avoidance and tolerance. The closest algal relatives to land plants, the Zygnematophyceae, use the latter, and how this is realized is of great interest for our understanding

Electroporation‐based delivery of proteins in Penium margaritaceum and other zygnematophycean algae
Abstract Zygnematophycean algae represent the streptophyte group identified as the closest sister clade to land plants. Their phylogenetic position and growing genomic resources make these freshwater algae attractive models for evolutionary studies in the context of plant terrestrialization.

The effect of increasing temperature and pCO2 on experimental pelagic freshwater communities
Abstract As the global climate is changing, average water temperatures and the supply of CO2 to water bodies are increasing. To determine how the effects of these changes on freshwater communities interact, we ran a month‐long factorial mesocosm experiment, in which we manipulated water temperature (heated, ambient) and pCO2 (preindustrial, ambient ...
