Microfauna

Microfauna refers to the microscopic or very small animals, typically invertebrates, that inhabit a particular environment. These organisms are generally too small to be seen with the naked eye and require a microscope for observation. They play a crucial role in ecosystem functions, participating in decomposition, nutrient cycling, and acting as a food source for larger organisms. microfauna encompasses a wide range of organisms, including protozoa, nematodes, rotifers, and tiny arthropods, often found in soil, aquatic environments, and within other organisms. They are vital indicators of environmental health, and their presence, absence, or abundance can reveal valuable information about the condition of their habitat. They represent an essential part of biodiversity that are often overlooked.

Microfauna meaning with examples

• Soil samples revealed a thriving microfauna population, composed of nematodes and protozoa, indicating a healthy and fertile ecosystem. This diverse community contributed to the breakdown of organic matter and the release of essential nutrients for plant growth. Observing the microfauna helped to gain insights into the soil's composition and its overall ability to support life within the ecosystem.
• The study of lake sediments revealed the presence of various microfauna, including rotifers and copepods. Their abundance fluctuated in response to changes in water quality and temperature. Monitoring these microscopic animals provided valuable information about the health of the aquatic environment and the impact of pollution and environmental changes.
• In examining the gut microbiome of a specific insect, scientists discovered a complex microfauna community, containing protozoa. This contributed to the digestion of cellulose. Studying these microscopic inhabitants provided insights into the insect's metabolic processes, offering a better understanding of the insect's dietary habits.
• Researchers analyzed the microfauna found in the biofilm on submerged rocks within a stream. The observed diversity of nematodes and other organisms reflected the water quality and indicated the availability of nutrients. Analyzing the biofilm offered valuable clues regarding ecosystem stability.
