A recent analysis of the Mediterranean Sea surface temperature showed significant annual warming. Since small picoplankton microorganisms play an important role in all major biogeochemical cycles, fluxes and processes occurring in marine systems (the ...

Critical knowledge gaps in the conservation and restoration of cold‐water corals
Abstract Introduction Critical knowledge gaps hamper effective conservation of threatened cold‐water coral (CWC) ecosystems, facing cumulative anthropogenic and climate pressures. This review provides a strategic roadmap for urgent, informed intervention.

Inter-annual ciliate distribution variation within the late stratification oxycline in a monomictic lake, Lake Alchichica (Mexico) [PDF]
Deep stratified tropical water bodies pass through prolonged periods of meta-hypolimnetic anoxia, and ciliates might play a very important role in the plankton community budget there.

Abstract The significant contribution of phytoplankton to global primary production is regulated by several abiotic and biotic factors, which are often difficult to account for in natural systems. To address these challenges, we perturbed a summer plankton community from Narragansett Bay, Rhode Island, USA, by manipulating the temperature and nutrient ...

Photosynthetic characteristics and diversity of freshwater Synechococcus at two depths during different mixing conditions in a deep oligotrophic lake [PDF]
We studied the photosynthetic characteristics and genetic diversity of Synechococcus assemblages at two different light and mixing conditions in a deep oligotrophic lake (Lake Maggiore, Northern Italy).

Abstract The California Current System (CCS) is characterized by dynamic coastal upwelling that profoundly influences plankton community structure and diversity and that leads to the emergence of large diatoms nearshore. This study presents a high‐resolution biogeochemical model of the CCS, coupling the Darwin ecosystem model with the Regional Ocean ...

Concentration-Dependent Patterns of Leucine Incorporation by Coastal Picoplankton [PDF]
ABSTRACT Coastal pelagic environments are believed to feature concentration gradients of dissolved organic carbon at a microscale, and they are characterized by pronounced seasonal differences in substrate availability for the heterotrophic picoplankton.

A prototype submersible sheathless flow cytometer designed for autonomous platforms
Abstract Development of submersible flow cytometers has allowed for continuous, in situ measurements of natural assemblages of phytoplankton cells. Here we introduce DeepCyte, a sensitive prototype submersible flow cytometer developed for deployment on autonomous platforms.
