Together, the researchers are studying the role played by each member of this coastal community—urchins, abalone, kelp, and so on—in order to create a mathematical model for the entire ecosystem. Fast forward two hundred years and even the 36-year-old McNeill has noticed the decreasing availability of traditional foods since he was a child. It is a cultural experience filled with symbolism and important nuggets of wisdom that can only be transferred through the sharing of an authentic Haida meal. Large and butter-colored, the gonads from these urchins are in prime condition—and they taste delicious. Spindel will go on to subject urchins collected from the area where the cull was conducted to the same tests inside the sealed tanks. “When you go down into the barrens,” says marine ecologist Lynn Lee, who is technical lead for the kelp forest restoration study, “only [those] in the first few meters are any good for the market—right against the kelp line in the shallows.” This is because urchins tend to avoid the shallowest areas, where breaking waves would thrash them about, and that leaves only a narrow strip of kelp to grow unencumbered. bioGraphic is powered by the California Academy of Sciences, a renowned scientific and educational institution dedicated to exploring, explaining, and sustaining life on Earth. Some are remarkably tolerant of the vibrations from the tool, while others twist their bodies around in a futile attempt to escape. For dessert, wild berry pie is accompanied by nettle tea. As he epoxies the tags onto each shell, the numbers are recorded in a logbook, along with the abalones’ sex, weight, and other data.

After collecting a small haul, McNeill and the rest of the team he supervises began systematically dispatching the unmarketable urchins with a hammer, leaving their shattered corpses behind to serve as food for fish and other invertebrates, their nutrients reclaimed by the ecosystem. Map updates are paused. The truth is, most of the urchins McNeill saw on that day weren’t worth the trouble. Sea lions followed the herring, and orcas followed the salmon.

This information will be critical, says Florida State University biologist Dan Okamoto, a scientific collaborator on the study, particularly when the interests of one set of stakeholders, like tour operators who stand to benefit from the eventual return of the charismatic otters, come into conflict with those of another, like commercial urchin fishermen. The first course featured a sampling of some staple dried snacks, which Roberta grew up on and adores. Jason G.

“The ecosystem response has been phenomenally quick, faster than I had thought.”. On a calm summer day, three months after that follow-up survey, Okamoto, the Florida State biologist, and his graduate student Nathan Spindel are sorting urchins aboard a floating laboratory in a sheltered bay in the Bischofs, a string of islands about 20 minutes by boat from Murchison Island. Next comes a salad topped with sea asparagus and crab. We can do that with all of the foods, including mushrooms, farmed foods, berries, venison, and fish.” At the Northern Haida Gwaii Hospital and Health Centre, the goal is to move entirely away from serving reheated meals to cooking from scratch. “In the early 1960s, everyone had their own house garden. He has written for National Geographic, Scientific American, Los Angeles Magazine, Teen Vogue, the BBC, and elsewhere. In areas kept free of otters through hunting, humans had the chance to partake of the invertebrate bounty. As the roe crunches between your molars, the flavor and sensations combine in a wholly unfamiliar way; imagine chewing pop rocks that taste like the sea. By doing this season after season, he’ll be able to determine whether the abalone in the experimental site, where the urchin population has been artificially reduced, are more likely to survive, how mobile they are, and whether they are more likely to reproduce than abalone in the control site.
