show decline in white tiger population over the past 10 years
Answers
Answer: Diseases, Habitat loss, Poor genetic diversity threat to tigers
Explanation:
Diseases
Various diseases also take their toll silently on the wildlife, including the predators. Many animals die and there is no way to ascertain the cause of their death. There are certain diseases that spread like epidemic and play havoc. Diseases like Feline Panleucopania (highly contagious and can be fatal), tuberculosis, sarcosystis, etc. have led to the decimation of many animals including tigers. Health management of wildlife, a relatively new area, is totally neglected. There is an urgent need to incorporate this field in the area of wildlife conservation
Habitat loss and prey depletion
The key findings from many years of study of tiger population have indicated that in many sites, tigers decline in numbers because of habitat loss and prey depletion rather than being killed directly. A tiger needs to eat about 50 deer-sized animals or 6,600 pounds of living prey every year. Wherever prey-base is adequate and good protection measures are in place tiger populations reach high numbers simply because the species breeds quickly
A recent study by the Wildlife Institute of India (WII) in Ranthambore Tiger Reserve (RTR), Rajasthan, India, says tiger population in the park has shown a loss of genetic diversity over the years. “RTR tiger population is showing loss of many alleles, which may be due to an isolated population without any genetic exchange,” said WII’s Dr S P Goyal, the investigator of the report — ‘Tiger Genome: Implications in Wildlife Forensics‘. Alleles are a group of genes that decide an animal’s hair colour and immunity, among other characteristics.
