Sloth bear, dhole, tiger most affected among apex predators globally due to road development: Study The sloth bear, tiger and dhole are among 36 apex predators worldwide affected the most due to road construction in their native habitats, a study published February 21, 2022, in the journal Nature, has stated. The sloth bear was the most affected predator as its habitat was in the Indian subcontinent, “where roadless areas are almost non-existent,” the study said. Some 97% of its area of distribution was covered by roads, which led to several instances of roadkills, or deaths due to collisions with vehicles. The sloth bear is followed by the dhole or Asiatic Wild Dog, which is, in turn, followed by the tiger, Asiatic black bear, clouded leopard, sun bear and Sunda clouded leopard. The researchers said Asiatic predators, especially in south Asia, were more exposed to roads. Roads are especially harmful for apex predators because their home ranges are large and thei...
