Introducing the Microbial Ecology of Changing Environments Collection

We are very pleased to be launching our Microbial Ecology in Changing Environments Collection, the product of a call for papers convened by PLOS ONE and our Guest Editors, Melissa Cregger and Stephanie Kivlin. The research in the Collection crosses disciplinary boundaries and represents a wide range of geographies, providing a snapshot of the diversity of research in contemporary microbial ecology. More articles will be added in due course, so please check back for updates!

Several articles highlighted in the Collection address the structure and dynamics of microbial communities in marine or aquatic environments. Three North American studies feature in the initial set of articles. Working in the Southern Californian Bight, Larkin and colleagues explored the effect of El Niño events on cyanobacterial populations [1]. Meanwhile, Vogel and colleagues found evidence for environmental and host-specific influences on microbial community structure on seagrass off the coast of Florida [2]. Finally, using a wetland mesocosm in Connecticut, Donato and co-workers performed an integrative study of microbial and plant responses to simulated chemical pollution [3].

The impact of natural disturbance on microbial communities was another theme that emerged in submissions to the Collection. In this first batch of articles, this is represented by the work of Eaton and colleagues, who examined how a major hurricane affected soil microbes in primary forests in Costa Rica [4].

The microbial ecology of manmade environments also features in the Collection. Maguvu and co-workers analysed the microbiome and physicochemical properties of drinking water production plants in South Africa, identifying significant variation in microbial community structure between facilities [5].

Last but not least, the Collection includes new research on the relationships between microbial communities living in dynamic environments within host organisms. Working in the UK, Garber and colleagues examined the effect of abrupt dietary changes in ponies on gut microbiota, with important implications for animal management [6].

The research in the Collection provides valuable insights into the mechanisms and consequences of microbial interactions with dynamic environments, and highlights the broad range of systems in which scientists are actively engaged in elucidating these phenomena.
