For 13 years, photographer Imre Potyó has ventured into restricted-access mine tunnels in the Börzsöny Mountains of Hungary to capture images of hibernating lesser horseshoe bat (Rhinolophus hipposideros). Despite their deep slumber, the bats occasionally wake to hunt insects that enter the dark caves. “In doing so, the bat leaves behind droppings that gradually accumulate
California is known for its giant, multi-laned highways bustling under bright blue skies. And while this infrastructure is useful to humans, the Golden State’s many highways represent an almost impenetrable barrier for wildlife. Soon, habitats on either side of the 10-laned 101 Freeway in Agoura Hills, California will be reconnected thanks to the world’s largest
Fall is here, and with it comes very determined deer. Mating season for the hoofed ruminants typically begins once temperatures dive and the days grow shorter, but the annual event also poses problems for humans. The deer have one thing on their mind, which means they pay even less attention to vehicles and roadways. In
A single bat colony contains hundreds or even thousands of the winged mammals. But with less-than-ideal eyesight and so many neighbors, how do mothers identify their pups amid the extremely crowded conditions? Writing in a new study published today in the journal Frontiers in Ethology, researchers say it often comes down to the subtle, unique
Our fingerprints, patterns on whale flukes, and fur patterns on cheetahs are examples of the natural ways we can tell one individual animal from another. For an Amazonian treefrog called the egg-eating spiny-backed frog (Osteocephalus oophagus), we need to look into their eyeballs. Fine black radial lines cross their golden irises, and form a pattern
Rattlesnake venom is a complex blend of necrotic toxins designed to quickly disrupt blood coagulation and destroy tissue cells. This effective biological weapon comes at a major premium, however. Snakes must regularly replenish their venom reserves, which means they need to dole out just the right amount with each bite. Injecting too little venom into
