Microcystis is a cyanobacterium that forms toxic blooms in freshwater ecosystems around
the world. Biological variation among taxa within the genus is apparent through genetic and …

Calcifying marine phytoplankton—coccolithophores—are some of the most successful yet
enigmatic organisms in the ocean and are at risk from global change. To better understand …

Sea-surface warming, sea-ice melting and related freshening, changes in circulation and
mixing regimes, and ocean acidification induced by the present climate changes are …

Phytoplankton population dynamics are the result of imbalances between reproduction and
losses. Losses include grazing, sinking, and natural mortality. As the importance of microbes …

Marine microorganisms constitute the largest percentage of living biomass and serve as the
major driving force behind nutrient and energy cycles. While viruses only comprise a small …

Nucleocytoplasmic large DNA viruses (NCLDVs) are ubiquitous in marine environments and
infect diverse eukaryotes. However, little is known about their biogeography and ecology in …

Although the spatial dimension of ecosystem dynamics is now widely recognized, the
specific mechanisms behind species patterning in space are still poorly understood and the …

The oceans contribute significantly to the global emissions of a number of atmospherically
important volatile gases, notably those containing sulfur, nitrogen and halogens. Such gases …

Phytoplankton form the base of marine food webs and are a primary means for carbon
export in the Southern Ocean, a key area for global pCO2 drawdown. Viral lysis and grazing …

Nucleo-cytoplasmic large DNA viruses (NCLDVs) constitute a group of eukaryotic viruses
that can have crucial ecological roles in the sea by accelerating the turnover of their …
