The role of microbial communities in oxic-anoxic regime shifts
In a study published in Nature Communications, Prof Jef Huisman, Prof Gerard Muyzer, PhD student Muhe Diao and colleagues assess the role of microbial communities in environmental regime shifts.
Gradual environmental changes (such as global warming or eutrophication) can lead to abrupt transitions in ecosystems. If such transitions lead to lasting changes in the structure and functioning of ecosystems, they are generally known as regime shifts.
Although such regime shifts have been well documented for a variety of environments, the role of microbial communities in such transitions is not very well understood.
Oxic-anoxic regime shifts
For this paper, the authors compare model and field data to improve our understanding of the role of microbial communities in oxic-anoxic shifts in aquatic environments, such as those occurring in eutrophic lakes.
A better knowledge and prediction of oxic-anoxic regime shifts is important to mitigate the effects of continued eutrophication and global warming.
