Tigers in Crisis

Promoting the Plight of Endangered Tigers and the Efforts to Save Them Tigers in Crisis is Produced by Endangered Species Journalist Craig Kasnoff to Promote the Plight of Endangered Tigers and the Efforts to Save Them.   OVERVIEW OF TIGERS IN CRISIS: Of the original nine subspecies of tigers, three have become extinct in the last 80 years; an average of one every 20 years. It has been predicted all tigers may become extinct in the wild within the next decade. Poaching, habitat loss and fragmentation have reduced the global population of tigers from over 100,000 in the 1900′s, to less than 4,000 in the 1970′s. Today, four of the remaining subspecies of tigers are considered endangered by the IUCN, while two of the subspecies...

Tiger Genome Sequencing Determines There Are Six Subspecies

The new finding could aid tiger conservation, with only 4,000 of the big cats remaining. Oct 25, 2018 ASHLEY P. TAYLOR with The Scientist There are six living subspecies of tigers: Bengal, Amur, South China, Sumatran, Indochinese, and Malayan, according a study published today (October 25) in Current Biology. The distinctions could help efforts to conserve the world’s 4,000 remaining tigers, the authors say.  For years, researchers have debated the number of tiger subspecies. In 2004, Shu-Jin Luo, now at the University of Peking, and colleagues proposed that there were six, based on an analysis of several molecular markers. Yet in 2015, other researchers claimed there were only two subspecies, using molecular, ecological, and morphological data. In the present study, which relied on whole-genome sequencing,...
