When Roswell Schaeffer Sr. was 8 years previous, his father determined it was about time he began studying to hunt beluga whales. Schaeffer was an Iñupiaq child rising up in Kotzebue, a small metropolis in northwest Alaska, the place a wholesome retailer of beluga meat was a part of making it by the winter. Every summer season, hundreds of those small white whales migrated to Kotzebue Sound, and hunts had been an annual custom. Whale pores and skin and blubber, or muktuk, was prized, not solely as a type of sustenance and a buying and selling commodity, but additionally due to the non secular worth of sharing the catch with the group.
Now, almost seven a long time later, Schaeffer is one in all just a few hunters who nonetheless spend the late weeks of spring, simply after the ice has melted, on Kotzebue Sound, ready for belugas to reach. Many individuals have switched to searching bearded seals, partly out of necessity: There merely aren’t sufficient belugas to maintain the group anymore.
Within the Nineteen Eighties, Kotzebue Sound’s beluga inhabitants started to dwindle, from hundreds to a whole bunch, after which to the handfuls or fewer that go to the area now. Kotzebue is just not alone. Though some shares are wholesome, beluga numbers have fallen off in round a half-dozen areas over the past 50 years. A long time in the past, searching, industrial whaling, and different influences pushed the whales towards the brink. Now, even after searching has ceased in some locations, stresses resembling local weather change, elevated ship visitors, and chemical pollution are a gathering storm that threatens to complete the job.
However some scientists suppose that understanding how the whales reply to those stresses may find yourself being as necessary as understanding the stresses themselves. Belugas, like chimpanzees, birds, people, and plenty of different animals, create cultures by passing information and customs from one era to the subsequent. With local weather change and different human actions reshaping the world at an alarming charge, belugas will probably must depend on modern cultural practices to adapt—genetic adaptation is just too sluggish to maintain up.
Cultural practices can develop into rote, nonetheless, and identical to people, different animals can maintain onto traditions lengthy after they’ve stopped making sense. One key query, in accordance with Greg O’Corry-Crowe, a behavioral ecologist at Florida Atlantic College, is: Will tradition carry the whales by?
“When the change is so seismic, possibly, and so speedy, you’re attempting to search for the innovators and the pioneers among the many social conservatives,” O’Corry-Crowe stated. On the similar time, Indigenous folks like Schaeffer are going through their very own quandary. Persevering with to hunt belugas might harm the whales’ probability of rebounding, but when Indigenous teams quit the apply, they may lose information that’s helped maintain them within the Arctic for hundreds of years.
Philosophers and scientists have lengthy recommended that animals can study. However even within the early 2000s, scientists debated the concept that animals accumulate information over generations. One animal that helped popularize that notion is the killer whale.
