Tiger Fragmentation

Study: Fragmentation of tiger habitat is leading to inbreeding, low survival


The study published in journal of Molecular Biology and Evolution published on February 16 suggests that there is inbreeding among Indian tigers, which is a result of isolated populations due to habitat loss.

A new research paper has concluded that fragmentation of habitat has already disrupted the natural evolutionary process in wild tigers and will continue to do so in future as anthropogenic pressures increase, leading to higher inbreeding and lower survival.

A team of researchers from Stanford University, the National Centre for Biological Sciences (NCBS) in Bengaluru, and various zoological parks and wildlife NGOs sequenced 65 genomes from four of the surviving tiger subspecies—Amur tigers, Bengal tigers, Sumatran tigers and Malayan tigers—over a period of three years to gain insight into the genomic variation in tigers.
