NEW URBAN LIZARD

What’s in news?

A new species of Urban lizard was founded.

Key data’s:

  • Name of the species: The zoological name of the new urban lizard was “Cyrtodactylus urbanus”.
  • Founded in: The new urban lizard was found in Guwahati, Assam.
  • This is the second Cyrtodactylus endemic to the Guwahati region, the fourth from Assam and the twelfth from Northeast India.
  • No. of gecko: This new species founded as 12th gecko from the Northeast.
  • Published in: The study on the urban benttoed gecko has been published in the latest edition of the journal – Zootaxa,
  • Different from other geckos: The new species is different in molecular structure, blotch and colour from the Cyrtodactylus guwahatiensis, or the Guwahati bent-toed gecko.
  • The new species differs from other members of the khasiensis group in mitochondrial sequence data (12.5–17.1 % uncorrected pairwise ND2 sequence divergence).
  • All bent-toed geckos in Northeast India were thought to be a single species, the Cyrtodactylus khasiensis found primarily in the Khasi Hills of Meghalaya.
  • Though the urban bent-toed gecko falls within the khasiensis group, it differs from other members of this group in mitochondrial sequence data as well as aspects of morphology. 

Data to know:

  • Guwahati is home to 26 species of amphibians, 57 species of reptiles, 214 species of birds and 36 species of mammals.
  • Reason for high bio-diversity: The city provides that edge for urban biodiversity to thrive because it encompasses 18 hills, eight reserve forest, two wildlife sanctuaries and a Ramsar site wetlands besides the Brahmaputra River.

Major tribes in Assam:

  • The major tribes were Tea Tribes, Koch Rajbongshi and Moran Community.
    • Tea Tribes – Originally brought by the British from Odisha, Madhya Pradesh, Bihar, Andhra Pradesh and West Bengal to work in the tea plantations of Assam during mid 19th century.
