soil-ecology
Soil ecology examines the complex interactions among soil organisms—including bacteria, fungi, and other microbes—and their physical and chemical environment. For plant science, these relationships are fundamental: soil communities drive nutrient cycling, influence root health, and shape the availability of essential minerals that determine plant growth and survival. Understanding soil biodiversity and aggregate formation helps researchers develop sustainable approaches to agriculture and ecosystem management.

Scientists reviewing research on fire ants found that the bacteria living in their guts play a key role in helping the ants fight off diseases and coordinate colony behavior. Understanding these microbial communities could open new doors for biological pest control that targets fire ant gut health instead of using broad-spectrum pesticides.
Fire ant guts host at least seven distinct bacterial genera — including Pseudomonas, Lactococcus, and Actinobacteria — that collectively support digestion, nutrient production, and immune defense against pathogens.
Gut microbiota composition directly influences colony-level behaviors including foraging efficiency and social interactions, suggesting a microbiome-behavior link similar to what has been observed in mammals.
Pathogenic fungi, bacteria, and viruses are natural population regulators of fire ants, and gut bacteria appear to be the primary mechanism by which colonies resist these natural enemies.
