Rare Marine Bacteria Found Crucial to Ocean Stability
Scientists studied bacteria living in oceans around the world.
They used information from more than 4,600 ocean samples.
The samples came from warm, mild and very cold parts of the oceans.
The researchers found that some rare bacteria are especially important.
These bacteria are not found in large numbers, but they help connect other microbes.
This makes ocean ecosystems more stable.
Ocean microbes also help move nutrients, support food chains and affect the climate.
The researchers hope their method will help people watch for changes in ocean health and protect marine environments.
Researchers at the Indian Institute of Technology Madras analysed more than 4,600 ocean samples from tropical, temperate and polar regions.
The study found that rare specialist bacteria contribute substantially to the stability of marine ecosystems.
Although less abundant than generalist bacteria, specialist microbes act as important connectors in microbial interaction networks.
Marine microorganisms help regulate nutrient cycling, support food webs and influence Earth’s climate, according to the researchers.
The researchers said their approach could help monitor biodiversity and guide conservation, while future work may examine individual species and strains.

“Marine microorganisms form the invisible foundation of ocean ecosystems. They regulate nutrient cycling, sustain marine food webs and play a vital role in controlling the earth’s climate. However, despite their ecological importance, the scientific community has only a limited understanding of the processes that govern the formation and resilience of these microbial communities.”
