Development of Microbial Indicators in Ecological Systems
Summary
This review examines the use of microorganisms as bioindicators of ecological health across forest, aquatic, desert, plateau, and artificial ecosystems, highlighting their high environmental sensitivity and underutilized potential compared to animal and plant indicators.
Indicators can monitor ecological environment changes and help maintain ecological balance. Bioindicators are divided into animal, plant, and microbial indicators, of which animal and plant indicators have previously been the most researched, but microbial indicators have drawn attention recently owing to their high sensitivity to the environment and their potential for use in monitoring environmental changes. To date, reviews of studies of animals and plants as indicator species have frequently been conducted, but reviews of research on microorganisms as indicator species have been rare. In this review, we summarize and analyze studies using microorganisms as indicator species in a variety of ecosystems, such as forests, deserts, aquatic and plateau ecosystems, and artificial ecosystems, which are contained in wetlands, farmlands, and mining ecosystems. This review provides useful information for the further use of microorganisms as indicators to reflect the changes in different environmental ecosystems.

A review on effective soil health bio-indicators for ecosystem restoration and sustainability
This review examines biological indicators that scientists use to measure soil health, including microbial diversity, enzyme activity, and earthworm populations. Healthy soil ecosystems depend on these biological components, which can be disrupted by pollutants including microplastics. The review is relevant because bio-indicators could serve as early warning tools for detecting the impact of microplastic contamination on agricultural soil quality.
Testate amoebae: a review on their multiple uses as bioindicators
This review evaluated testate amoebae as bioindicators across a wide range of environmental conditions, finding these unicellular protozoans are sensitive, globally distributed monitors useful for biomonitoring wetlands, soils, and freshwater systems including detecting microplastic contamination.
Bioindicators of Microplastics
This chapter provides a comprehensive overview of bioindicators for detecting microplastic pollution, covering organisms from bacteria and algae to invertebrates and vertebrates that serve as early warning sentinels for plastic contamination in the environment. The authors assess the methodological approaches for using these bioindicators and their utility for monitoring ecological health in microplastic-affected ecosystems.
