Changes in microbial communities along redox gradients…
Principle component analysis of variation in microbial community structure by topography and depth. The percentage of total variation in weighted UniFrac distance among samples explained by the first two principle components is shown in parentheses. Topography is indicated by shape (triangles = polygon rims, circles = polygon centres) and depth is indicated by colour (green = 6–10 cm, blue = 16–20 cm, red = 26–30 cm and pink = 36–40 cm).
In collaboration with Janet Jansson (now with PNNL), we published this study in Environmental Microbiology Reports, showing that redox gradients are a dominant force in structuring microbial communities in wet Arctic tundra soils.
