Investigating the microbial ecology of coastal hotspots of marine nitrogen fixation in the western North Atlantic
Variation in the microbial cycling of nutrients and carbon in the ocean is an emergent property of complex planktonic communities. While recent findings have considerably expanded our understanding of the diversity and distribution of nitrogen (N2) fixing marine diazotrophs, knowledge gaps remain re...

Variation in the microbial cycling of nutrients and carbon in the ocean is an emergent property of complex planktonic communities.

Using quantitative 16S and 18S V4 rDNA amplicon sequencing, we surveyed eukaryotic and prokaryotic microbial communities from samples collected in August 2016 and 2017 across the Western North Atlantic.
