aeroplankton

Aeroplankton refers to the diverse community of microscopic organisms that drift in the Earth's atmosphere. These include bacteria, archaea, fungi, pollen, spores, and tiny invertebrates like mites and springtails. Unlike their aquatic counterparts, aeroplankton are carried by air currents and can travel vast distances, playing a significant role in global biogeochemical cycles and the distribution of life.

The composition and abundance of aeroplankton vary greatly depending on location, altitude, weather conditions, and season. For example, pollen and fungal spores are more prevalent during certain times of the year, while bacteria and archaea are found year-round. These airborne microbes can influence cloud formation and precipitation through a process called bio-aeroclonization, where they act as ice nuclei or cloud condensation nuclei.

Research into aeroplankton is crucial for understanding various ecological processes, including disease transmission, the spread of allergens, and the potential for microbial life to colonize new environments. Sampling techniques involve collecting air at different altitudes using specialized equipment, followed by laboratory analysis to identify and quantify the organisms present. The study of aeroplankton highlights the interconnectedness of Earth's systems and the pervasive nature of life.
