âFDA-clearedâ means a test system has been reviewed by the FDA and has been determined to be substantially equivalent to a test system already legally marketed for the same use. This could apply to waived, moderate or high complexity test systems.
The study estimates that there are now 3,890 wild tigers, up from 3,200 in 2010, when countries announced a historic commitment to double the population by 2022. Countries appear to be heading toward their goal, and this is the first time tiger numbers have been increasing globally in more than a hundred years.
As the century drew to a close, only 5,000 to 7,500 were left in the wild, and captive tigers may now outnumber wild ones. Since then, the worldâs tiger population has declined to about 3,200 animals. The South China tiger (P. tigris amoyensis) is the most endangered, with only a few dozen animals remaining. The Malayan subspecies (P. tigris jacksoni), which was determined to be genetically distinct from the Indo-Chinese subspecies (P. tigris corbetti) in 2004, is composed of perhaps 500 individuals.
