Etymology
The term 'microfauna' originates from the Greek word 'mikros,' meaning 'small,' and 'fauna,' which refers to the animal life in a particular region or time period. It was first used in the early 20th century as biologists began to explore the diverse range of small animals inhabiting various ecosystems. Initially, studies focused on soil and aquatic microfauna to better understand their roles in the food web and ecosystem functions. Over time, the term has expanded to include a wider range of microscopic life, including those found in host organisms, such as the human gut. The understanding of microfauna has evolved significantly, leading to advancements in ecological research and its relevance to biodiversity, environmental health, and even the development of biotechnological applications.
