The consequences of climate change may directly or indirectly impact the marine biosphere. Although ocean stratification has been recognized as one of the crucial consequences of ocean warming, its impacts on several critical aspects of marine microbes ...

Interplay of Spatial Structure and Interactions in Microbial Communities
A description of the interplay between microbial growth and interactions, the spatial structure of the environment and the spatial organisation of microbial populations can improve our understanding of the ecology of microbial communities. We review previous studies that highlight different aspects of this interplay.

Bacterioplankton Metabolism in Hydroelectric Reservoirs
Reservoirs are anthropogenic aquatic systems accounting to a substantial portion of the contemporary distribution, and dynamic, of freshwater systems across a wide geographical gradient throughout the Globe, with potential to increase its participation due to the growth of world’s economy and need for energy.

Cyclonic cold-core eddy in the eastern North Atlantic. II. Nutients, phytoplankton and bacteriaplankton [PDF]
A cyclonic cold-core eddy in the Northeast Atlantic of about 100 km in diameter at the sea surface was investigated in May 1985, approximately 3 wk after it had separated from the Polar Front.

Top‐Down and Bottom‐Up Processes Jointly Explain Mesopredator Movement and Foraging Ecology
This study integrates top‐down (polar bear habitat selection) and bottom‐up (fish distribution) processes to test how mesopredators (ringed seals) balance risk–reward tradeoffs in habitat selection. Ringed seals reduced their space use and foraging time in response to predation risk, yet accepted higher risk when prey diversity was elevated ...

Active bacterioplankton community response to dissolved ‘free’ deoxyribonucleic acid (dDNA) in surface coastal marine waters [PDF]
Seawater contains dissolved ‘free’ DNA (dDNA) that is part of a larger <0.2 μm pool of DNA (D-DNA) including viruses and uncharacterised bound DNA.

Bacterioplankton play a key role in marine waters facilitating processes important for carbon cycling. However, the influence of specific bacterial populations and environmental conditions on bacterioplankton community performance remains unclear.

Microalgae blooms are a frequent occurrence in coastal waters worldwide. It is reasonable to assume that these blooms have various influences on bacterial communities, which in turn may affect the development and dissipation of the bloom.

Aqueous extracts from Pistia stratiotes and Pontederia crassipes inhibit Microcystis aeruginosa while stimulating its associated microbiota. Reintroduction of microbiota into fresh cyanobacterial cultures reduced allelopathic effects, likely through allelochemical degradation and antioxidative responses.

Inorganic nutrient limitation of oceanic bacterioplankton [PDF]
Although it is commonly accepted that dissolved organic carbon (DOC) of algal origin limits bacterial growth in pelagic systems, there are relatively few empirical studies documenting this effect. Depending on site and season, both organic and inorganic nutrients can limit the growth of freshwater bacteria.
