Overview:

A study on the firefly species and their habitats in the Anamalai Tiger Reserve (ATR), has underscored the need to take proactive conservation measures to preserve their habitat and safeguard the ecosystem.

Key points:

  • The study stressed the need to minimise the impact of artificial light on the communication and mating behaviours of fireflies.
  • Three species of fireflies — Asymmetrica humeralisAbscondita genus (species unknown) and Curtos sp — were identified. They exhibited variation in size morphology, but shared similar types of habitat with overlapping zones.
  • The well-preserved core zone of the ATR serves as a critical sanctuary for firefly activity, especially during the crucial breeding season in April and May.
  • As fireflies rely on bioluminescence for communication and mating, artificial lights in the buffer zone of the reserve may disrupt their delicate synchronisation and mating behaviour.

 

Key facts about the Anamalai Tiger Reserve

Q1) What are Shola forests?

These are a unique type of high-altitude, evergreen forest ecosystem found in the Western Ghats mountain range of India. These forests are characterized by their distinctive vegetation structure and play a critical role in maintaining biodiversity and providing ecological services.
