Our ability to describe the highly diverse pool of low abundance populations present in
natural microbial communities is increasing at an unprecedented pace. Yet we currently lack …

Microbial communities in the coastal Arctic Ocean experience extreme variability in organic
matter and inorganic nutrients driven by seasonal shifts in sea ice extent and freshwater …

Microorganisms are often applied as biofertilizer to crops to stimulate plant growth, increase
yields and reduce inorganic N application. The survival and proliferation of these …

Cyanobacterial blooms (CBs) and concomitant water quality issues in oligotrophic/
mesotrophic waters have been recently reported, challenging the conventional …

Genome reconstruction from metagenomes enables detailed study of individual community
members, their metabolisms, and their survival strategies. Obtaining high quality …

Polycyclic aromatic hydrocarbons (PAHs) pose a great threat to human health and
ecological system safety. The interception of nitrogen is common found in the riparian zone …

Nitrogen-fixing or diazotrophic microbes fix atmospheric nitrogen (N2) to ammonia (NH3+)
using nitrogenase enzyme and play a crucial role in regulating marine primary productivity …

We describe diazotrophs present during a 2015 GEOTRACES expedition through the
Canadian Arctic Gateway (CAG) using nifH metabarcoding. In the less studied Labrador …

Irrigation with brackish water has been widely applied in many regions of the world as an
efficient alternative to conserve freshwater resources. Although it has limited soluble salt …

Microorganisms inhabiting saline environments are an interesting ecological model for the
study of the adaptation of organisms to extreme living conditions and constitute a precious …
