J & K CETJ & K CET 2014Biodiversity and Conservation

Solution:

The IUCN Red List $(2004)$ documents the extinction of $784$ species in the last $500$ years. The list includes $338$ vertebrates, $359$ invertebrates, and $87$ plants. Some examples of recent extinctions include the dodo (Mauritius), quagga (Africa), thylacine (Australia), Steller's Sea Cow (Russia) and three subspecies (Bali, Javan, Caspian) of the tiger. Reasons of extinct are habitat loss, co-extinctions, overexploitation and alien species invasions. So, the correct answer is ' $338$ vertebrates, $359$ invertebrates and $87$ plants'.
