How termite behaviour is linked to a warming world
Subject : Environment
What did the study find?
- A recent study has found that termites decompose wood at a much higher rate in warmer conditions.
- For every 10 degrees Celsius increase in temperature, their decomposition activity goes up by almost seven times.
- These wood-eating termites were able to survive in warm and dry conditions, unlike microbes that need water to grow.
Details of the study:
- The study revealed that as the Earth gets warmer, termites will rapidly spread across the world.
- This could, in turn, lead to a further rise in global temperatures, because these small insects while consuming deadwood release carbon into the atmosphere.
- It shows that the movement of an organism as small as a termite can cascade to impact the rate that wood—a global carbon stock—is decomposed.
- 12 of the world’s 13 most invasive termite species could increase significantly in distribution by 2050.
Termites:
- There are around 3,000 species of termites across the world, including the ones that consume plant material and even soil. Prominent among them are the wood-eating termites.
- They play a vital role in the planet’s ecosystem i.e. decomposing dead wood.
How will they increase global warming?
- Termites release carbon from dead wood in the form of carbon dioxide and methane, two of the most important greenhouse gases.
- So, an increase in termite population and their faster decomposing activity can cause more greenhouse emissions, resulting in a hotter planet.
Other consequences of global warming:
- Imbalance in the health of the ecosystem.
- Melting of polar ice leads to disruption in the food chain of the arctic region.
