"...declawing a cat is not like trimming our fingernails; rather, it is removing part or all of the last bone of each digit."

Tigers in Nepal were two to three times more likely to cross highways when COVID-19 lockdowns led to dramatic reductions in traffic.

"Tiger deaths along the roads and railways would reduce the tiger population from around 130 animals to just 50 animals over a 20-year period."

Tigers bred on farms in Asia end up in high-pressure cookers, where bones are dissolved to make "tiger bone glue," thought to cure a variety of ailments.

A "genetic rescue" involving the mating of different subspecies may offer the best way to save increasingly fragmented tiger populations.

Biologists explain why private zoos like those in "Tiger King" are bad for big cats, what the series got wrong, and what's next for tiger conservation.

Plans to build nearly 15,000 miles of road through tiger habitats in Asia by mid-century will up the risk for the big cat's extinction, researchers warn.

A new way to track endangered species uses bits of DNA in things like feces and saliva. "It's CSI meets conservation biology."
