microbial ecologyMicrobial ecology is the study of interrelationships between microorganisms and the living and non-living aspects of the environments that they inhabit. Microorganisms are important players in Polar habitats, where they are major drivers of biogeochemical cycles in aquatic and terrestrial ecosystems. In the Arctic, for example, the thawing of permafrost could lead to increases in microbial activities and carbon decomposition, resulting in accelerated release of greenhouse gases. In the Antarctic, microorganisms are important in mediating nutrient cycling in surface lakes and subglacial environments, which are thought to carry important nutrients to the surrounding Southern Ocean. Additionally, studies focusing on the survival mechanisms of microbes exposed to sub-zero conditions or freeze-thaw cycles contribute to our understanding of the resilience of life and to advances in the fields of biotechnology and astrobiology. Answering basic questions about microbial ecosystems can be difficult, as the systems cannot be observed directly, but recent technological advances allow the construction of molecular “blueprints”, which are keys to describing and understanding microbial ecosystems. Large quantities of these molecular data help inform our understanding of microbial population structures and metabolic activities, as well as how these elements interact with the environment as a whole. Combining current molecular approaches with field-based measurement and laboratory-based culture studies allows today’s microbial ecologists to examine important issues ranging from the impact of changing climate on nutrient cycling to life’s ability to survive in extreme environments.
