- According to the global analysis of nematodes published in Nature,there are about 57 billion nematodes for every human being on Earth.
- The researchers have said that Sub-Arctic regions have the highest abundance of nematodes followed by temperate regions and tropical regions.
- Nematodes prefers colder region as soil organic matter content is the key driver for nematode abundance.
- Further,the low temperature and high moisture in the sub-Arctic regions reduces the decomposition rate of organic matter.This leads to accumulation of organic matter and the nematodes happily thrive on them.
- Nematodes are worm shaped nearly microscopic animals,many of which are virtually invisible to the unaided eye when they are in the soil or within plant material.
- These are roundworms and their size can vary from a tiny 0.2 millimetre to a few metres.They are responsible for around 2.2% of the total carbon emission from soils.
- The nematodes play a crucial role in the environment as they are responsible for production of ammonia of the soil and also a bioindicator of soil ecosystem’s health.
