Amongst tetrapods, amphibians entail the highest number of threatened and data deficient species, which has put them in the limelight of research in animal ecology and conservation. Endemic species have evolved and adapted to a particular set of environmental conditions. Hence, these are more vulnerable to environmental changes and are susceptible to population declines because of their restricted distribution ranges.
The Murree Hills Frog and Hazara Torrent Frog are endemic to Pakistan and South Asian countries. They are associated with the torrential streams and nearby clear water pools situated at high elevation. These frogs are susceptible to threats like habitat degradation, urbanization, and climate change. A recent study published in the-open access journal Biodiversity Data Journal reports that these endemic frogs do not show much movement within and outside their habitat.
“We have, for the first time, used radio-transmitters (VHF) on frogs endemic to Himalayan region to understand their ecology,” explains Dr. Muhammad Rais, Assistant Professor at the Herpetology Lab in the Arid Agriculture University, Rawalpindi, and lead author of the study. “Surprisingly, the Murree Hills Frog and Hazara Torrent Frog depend heavily for their survival on particular stream(s).”
“We suggest carrying out additional long term studies by incorporating multiple adjacent stream systems to better understand dispersal and colonization in these frogs,” he says in conclusion.
