Microscopic soil amoebae could signal climate-driven ecosystem shifts

Soil Health
The soil microbes feeding your tomatoes and roses get recycled by amoebae that graze on bacteria and release the exact nutrients your plants pull up through their roots.
There are tiny single-celled creatures called free-living amoebae living in your garden soil, puddles, and even house dust. They eat bacteria and other microbes, and when they do, they release nutrients back into the soil that plants can absorb. Scientists are now arguing that watching how these amoebae respond to heat, drought, and changing land use could help predict bigger shifts in soil health, water quality, and even disease risk.
Key Findings
Free-living amoebae graze on bacteria, driving nutrient turnover that feeds plant-accessible mineral pools in soil
They inhabit soil, water, air, and built environments, and host bacteria, fungi, and viruses, including some opportunistic pathogens
Researchers propose incorporating amoebae as ecological indicators in One Health and planetary microbiome surveillance frameworks to track climate-driven microbial change

Tiny amoebae that live in soil and water graze on bacteria and release nutrients plants can use, and scientists think tracking them could become an early-warning tool for how climate change is reshaping ecosystems and spreading disease.

Integrating free-living amoebae into climate-microbiome and One Health frameworks.
Climate change is altering microbial ecosystems at a global scale, yet the role of free-living amoebae within these shifting microbiomes remains incompletely understood. Free-living amoebae occupy ...

Climate adaptation in plants refers to the physiological and evolutionary mechanisms through which plants adjust to changing environmental conditions, including temperature shifts, altered precipitation patterns, and seasonal variations. Understanding these processes is essential for plant science
