Feeding strategies and resource partitioning mitigate the effects of oligotrophy for marine cave mysids [PDF]
We investigated how large populations of several mysid species can coexist in oligo - trophic underwater marine caves and their relationships in the marine cave food web using car- bon and nitrogen stable isotopes. Isotopic signatures indicate food partitioning among the 5 spe- cies of cave-dwelling mysids from the northwest Mediterranean Sea we ...

Nano-Sized and Filterable Bacteria and Archaea: Biodiversity and Function
Nano-sized and filterable microorganisms are thought to represent the smallest living organisms on earth and are characterized by their small size (50–400 nm) and their ability to physically pass through <0.45 μm pore size filters.

OUTPACE long duration stations: physical variability, context of biogeochemical sampling, and evaluation of sampling strategy [PDF]
Research cruises to quantify biogeochemical fluxes in the ocean require taking measurements at stations lasting at least several days. A popular experimental design is the quasi-Lagrangian drifter, often mounted with in situ incubations or sediment ...

Abstract The twaite shad (A. fallax), an anadromous fish species belonging to the Clupeidae family, has experienced population declines throughout Europe. This decline is attributable to a range of anthropogenic pressures, including migration barriers, environmental pollution, habitat degradation, predation by invasive species and unsustainable fishing

Species assemblages of zooplanktonic crustaceans in mountain shallow ponds of Chile (Parque Cañi)
Even though the Chilean lakes are characterized by their oligotrophy, a transition from oligotrophy to mesotrophy, due human intervention, has been reported in some lakes.

Abstract Diverging community responses of plants and microbes to global change have the potential to disrupt ecosystem function and resiliency. Saltwater intrusion and sea level rise (SWISLR) threaten coastal ecosystems and are associated with multiple stressors—salinization, alkalinization, and inundation.
