Non-Invasive Genetics

Majority of Tiger studies have relied on Conventional Techniques such as: 

  • Surveys based on signs (e.g. pugmarks, scrapes, scat and urination pattern)
  • Interviews with local inhabitants
  • Camera trapping
Conventional techniques possess several disadvantages like:
  • Extended field time (~40-50 days)
  • High cost of field work
Genetic monitoring has become a established scientific and convincing data-collection approach with great potential for wildlife and conservation biologists
Modern Genetic technique, by exploiting individual uniqueness, can utilize variety of non-invasive genetic samples like:- 
hair, feces, urine, feathers, shed skin, saliva, egg shells to collect critical data eg.,
  • To identify presence of rare or elusive species, 
  • To count and identify individuals, 
  • To determine gender, 
  • To identify diet items, 
  • To evaluate genetic diversity, population structure, and mating system.
  • To estimate wildlife populations without handling, capturing, or even observing individual animals.
