Abstract The EU Marine Strategy Framework Directive 2008/56/EC (MSFD) defines a
framework for Community actions in the field of marine environmental policy in order to …

The microfossil record demonstrates the presence of eukaryotic organisms in the marine
ecosystem by about 1,700 million years ago (Ma). Despite this, steranes, a biomarker …

Polar marine environments host a complex assemblage of cold-adapted auto-and
heterotrophic microorganisms that affect water biogeochemistry and ecosystem functions …

Very few studies have investigated marine microbial colonization in polar regions, but
climate-changing scenarios stress the importance of these investigations to protect life in …

Two distinct pressurized hypersaline brine pockets (named TF4 and TF5), separated by a
thin ice layer, were detected below an ice-sealed Antarctic lake. Prokaryotic (bacterial and …

Prokaryotes represent a major fraction of marine biomass and play a key role in the global
carbon cycle. We studied the vertical profiles (0–3500 m) of abundance, viability, and activity …

Among extreme environments, bioaerosol includes a wide range of primary atmospheric
organic particles associated with and emitted by living and dead organisms. Bioaerosol …

The response of heterotrophic bacterioplankton to the addition of macrophytic dissolved
organic matter (DOM) and temperature was investigated in the Red Sea. We added 40 μ mol …

Heterotrophic prokaryotes (HPs) represent the largest fraction of living biomass in the ocean.
Comprehensively understanding the spatio-temporal variability of their controlling factors …

In coastal lakes the role of microorganisms in driving nutrients regeneration at different water
depths and in sediments is not yet fully understood. The dynamics of microbial (algal and …
