Scientists have discovered one of the rarest in the world chameleon “Stick on survival” after fear of extinction due to its large scale since its first discovery in the 1990s deforestation, A new study was found.
Researchers have discovered a population of Chapman pygmy chameleons (Kalehakamereka) Survive with a small patch Rainforest In southern Malawi in southeastern Africa.
Discovered in 2016 by a research team at the South African National Biodiversity Institute (SANBI) and the Malawi Museum. They saw the first chameleon at the edge of the forest.
“When I found it, I got goosebumps and started flying around,” said Crystal Tory, a herpetologist at SANBI and the University of the Witwatersrand in South Africa. Said in a statement.. “I didn’t know if I could get any more, but when I entered the forest there were a lot, but I don’t know how long it will last.”
Chapman’s Pygmy Chameleon grows to a length of only 2.2 inches (5.5 centimeters) and walks on the floor. They disguise themselves by matching the pattern of dead leaves. According to a statement, they were first discovered in the declining rainforest of Malawi’s hills in 1992 and then released to another forest, also near Mikundi in Malawi, increasing their chances of survival.
The team compared the latest satellite images of the Malawi hill forest with those taken in the 1980s and estimated that the forest was reduced by 80%. Researchers have identified areas where chameleons may still be alive, and walked down forest paths with torches on nights when chameleons were easy to find.
They found 17 adult chameleons in two forest areas of Malawi hills, and 21 adult chameleons and 11 juveniles in one patch near Mikundi. According to the survey, there may be more chameleons in other forest patches that the team could not investigate.
Researchers took small tissue samples from the tails of some adult chameleons and analyzed them before returning them to where they were found. DNA.. The chameleon sequences from the three forest patches differed significantly. This suggests that chameleons are isolated within forest patches and are unable to move between them to propagate and share genes.
“Before this species reaches a point where it cannot return, deforestation requires urgent attention. Urgent conservation efforts, such as stopping deforestation and restoring habitat, are needed to facilitate connectivity. is.”
Much of the Malawi Hills forest has been logged and converted to agriculture. The team is calling for a comprehensive action plan to protect endangered chameleons from extinction.
