Breaking Waves: Ocean News

From humpbacks learning the latest songs to sperm whales’ ‘clan codas’, drones and AI learning are helping reveal another dimension to the concept of culture In 2015, the whale researcher Valeria Vergara pitched a small tent at the icy water’s edge on Somerset Island in the remote Canadian high Arctic, shrouded in a freezing fog so thick she struggled to see her own hands. She trailed a cord out to the coast and plopped a hydrophone into the water to record the calls of belugas. As many as 1,000 of the whales, accompanied by their newborn calves, frequented the surrounding bay. Belugas’ ceaseless chatter, made up of dozens of unique sounds, is crucial to keeping these creatures connected in the dim, turbid waters of the Arctic. Continue reading...

Bears killed 13 people in Japan last year, as a lack of forest foods increased conflicts. Yet some say the country’s controversial cull could threaten the endangered species Every summer, millions of people escape the heat and humidity of Tokyo by heading to the tranquil resort town of Karuizawa in Japan’s Nagano prefecture – just an hour by bullet train from the capital.

It would be the ideal nature retreat – if it wasn’t for the bears. From June to August, bears often move close to Karuizawa, feeding on the mulberries, ants, leaves and cherry blossoms that grow near the town. Unlike nuts, these foods are low in calories, spurring the bears to seek out further sustenance. “They’re more likely to get close to residential spaces to see what they can find,” says Amelia Hiorns, a British zoologist who previously worked with Picchio Wildlife Research Centre in the town. “This combines with the busiest season for tourists.” Continue reading...

Comté, beaufort and abondance makers can temporarily supplement cows’ diets as there is ‘no grass left to eat’ Strict production rules will be loosened for some of France’s most famous cheeses after drought and repeated heatwaves dried out grazing pastures, threatening the livelihoods of traditional dairy workers. Comté, a hard cheese made from raw cows’ milk in the Jura mountains, is France’s top-selling traditional cheese, with more than 62,000 tonnes produced last year. The government announced on Wednesday that its producers would be granted a temporary change to strict rules on grazing after farmers said extreme heat had scorched their pastures, putting production at risk.
