What are the broader implications of this discovery for
the Dravidogecko genus in Western Ghats of India?
The discovery of Dravidogecko coonoor carries several
broader implications for the Dravidogecko genus in the Western Ghats,
highlighting both its significant biodiversity and critical conservation
challenges:
•Increased Known Species Diversity: The
identification of Dravidogecko coonoor means that the total number of
Dravidogecko species found across the Western Ghats now stands at nine. This
significant increase from the initial understanding (where the Coonoor gecko
was once thought to be Dravidogecko anamallensis) underscores the rich and
previously underestimated diversity within this genus in the region. The fact
that extensive surveys throughout the Western Ghats led to the discovery of
eight different Dravidogecko species suggests a dynamic and diverse
evolutionary history for the genus.
•Unique Endemism to High Elevations: The
Dravidogecko genus is notable as the only gecko species endemic to the high
elevation regions of the Western Ghats. This unique characteristic makes the
genus particularly important for understanding the specialized biodiversity of
these montane ecosystems and emphasizes their reliance on these specific
habitats.
•Widespread Conservation Concerns: The discovery of
Dravidogecko coonoor as a "potentially threatened gecko species"
whose known population exists entirely outside the protected area network
raises significant concerns for the entire Dravidogecko genus. This
vulnerability is due to factors such as habitat fragmentation, deforestation,
and potentially climate change. Given that Dravidogecko species inhabit areas
characterized by a matrix of montane forests and monoculture plantations amidst
human habitations, with dominant human influence and only partial vegetation
cover, it implies that other species within the genus are likely facing similar
pressures, making their long-term survival a considerable challenge.
•Ongoing Research and Discovery Potential: The
history of the Coonoor gecko's classification, initially mistaken for
Dravidogecko anamallensis before extensive surveys revealed it and eight other
distinct Dravidogecko species, suggests that there may still be more
undiscovered or unclassified species within the genus across the Western Ghats.
This highlights the importance of continued herpetological surveys and genetic
studies in this biodiverse region.
