Airborne bacterial populations above desert soils of the McMurdo Dry Valleys, Antarctica [PDF]

, 2014
Bacteria are assumed to disperse widely via aerosolized transport due to their small size and resilience. The question of microbial endemicity in isolated populations is directly related to the level of airborne exogenous inputs, yet this has proven hard
