When Roswell Schaeffer Sr. was 8 years outdated, his father determined it was about time he began studying to hunt beluga whales.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 means of the winter. Every summer time, 1000’s 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 religious worth of sharing the catch with the neighborhood.
Now, practically seven many years later, Schaeffer is considered one of 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 looking bearded seals, partly out of necessity: There merely aren’t sufficient belugas to maintain the neighborhood anymore.
Within the Nineteen Eighties, Kotzebue Sound’s beluga inhabitants started to dwindle, from 1000’s to tons of, after which to the handfuls or fewer that go to the area now. Kotzebue will not be alone. Though some shares are wholesome, beluga numbers have fallen off in round a half-dozen areas over the past 50 years. Many years in the past, looking, industrial whaling, and different influences pushed the whales towards the brink. Now, even after looking 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 assume 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 data and customs from one era to the following. With local weather change and different human actions reshaping the world at an alarming fee, belugas will seemingly must depend on revolutionary cultural practices to adapt—genetic adaptation is just too sluggish to maintain up.
Cultural practices can turn into rote, nevertheless, and identical to people, different animals can maintain onto traditions lengthy after they’ve stopped making sense. One key query, in line with Greg O’Corry-Crowe, a behavioral ecologist at Florida Atlantic College, is: Will tradition carry the whales by means of?
“When the change is so seismic, perhaps, and so speedy, you’re making an attempt to search for the innovators and the pioneers among the many social conservatives,” O’Corry-Crowe stated. On the identical time, Indigenous folks like Schaeffer are dealing with their very own quandary. Persevering with to hunt belugas could harm the whales’ probability of rebounding, but when Indigenous teams quit the apply, they may lose data that’s helped maintain them within the Arctic for 1000’s of years.
Philosophers and scientists have lengthy steered that animals can be taught. However even within the early 2000s, scientists debated the concept that animals accumulate data over generations. One animal that helped popularize that notion is the killer whale.
