Need a break from political news? Hey, look, the ocean!

We’ve seen big declines in wild bee populations. That’s not just bad for the fuzzy little bees; it could drive up prices for almonds, blueberries, and other pollinator-dependent treats.

The challenge is knowing what would help them. Do we focus on preserving habitat and flowers? Or should we focus on certain pesticides? Is climate change behind this, too? It’s hard to say because bees are hard to study. It’s relatively easy to count long-legged pronghorns or wide-winged condors compared to counting the gnat-sized Perdita minima, the world’s tiniest bee.

That’s why a research team at the University of Missouri has been putting little microphones in alpine meadows. When those mics record buzzing, the team’s software analyzes the noise to tell scientists the number and species of bees visiting. They just published a paper, showing that their methods work.

This breakthrough could allow regular folks to collect solid scientific data from the safety of their porch. Farmers could “monitor pollination of their orchards and vegetable crops and head off pollination deficits,” said Candace Galen, a biological science professor who led the university’s research team, in a news release.

Interested? The group is working on an app that would let you collect bee data with your smartphone.

Satirist writes obituary for the Great Barrier Reef. Internet takes him all too seriously.

On the list of things people are lamenting online this week is how humans let the #GreatBarrierReef perish from the face of the Earth. This comes in response to a tongue-in-cheek obituary for the natural wonder published in Outside, “Great Barrier Reef (25 Million BC-2016),” by the writer Rowan Jacobsen. Almost immediately, the un-ironic eulogies and self-hatred came pouring in:

Of course, they didn’t grasp the satire; the reef isn’t dead, not yet. According to early assessments out Thursday from the Great Barrier Reef Marine Park authority, 22 percent of the reef died in this year’s horrific bleaching. It was the worst such event on record, and a disaster whose effects will no doubt be felt for decades. But that’s still a far cry from dead. During the worst of the Southern Hemisphere summer heat, 93 percent of the reef was experiencing some bleaching. Six months later, much of that coral has recovered.

Scientists and activists quickly took to social media to refute Jacobsen’s piece. Here’s one example:

So Grist reached out to some others to help set the record straight.

“I tend to be pretty measured in my responses to pieces like this,” said Stephanie Wear, senior scientist at the Nature Conservancy. “But this article has gotten me pretty worked up, and I am certain I am not alone just by reading my social media feeds today.”

Wear continued: “What we are facing right now is something akin to a recession — a coral reef recession. The key now is for us to identify the best ways to manage through this recession while the global community comes together to make good on the Paris agreements. Doing this will lead coral reefs out of recession and give them and the half billion people that depend on them a fighting chance.”

In fact, Australia continues to make progress on efforts to protect and improve the health of the reef, as Science reported last month. Much remains to be done — above all, addressing the sources of pollution that cause global warming and coral bleaching.

“The danger of this story is that many folks won’t realize it is satire and will feel it is too late for coral reefs,” says Mark Eakin, the lead coordinator of NOAA Coral Reef Watch. “As depressing as the news has been for much of the last two years, I still have hope that we can save many of the world’s coral reefs.”

Jacobsen is not the first to write an obituary for the Great Barrier Reef — the Guardian published an impressive multimedia obituary back in March 2014 — and his surely won’t be the last. There’s no doubt that corals are in for a rough couple of decades. But this kind of scare-’em-straight environmental messaging has limited use. From what we know about the psychology of listening to these kinds of messages, we tend to tune out when the bad news gets too overwhelming. To get people engaged in solving problems, you have to focus on what can be done to help.

Terry Hughes, the Australian researcher whose surveys of the damaged reef this summer led to impassioned pleas to help protect it, put it bluntly: “You don’t write the obituary of a loved one when they are diagnosed with a serious illness — you help them fight for their life.”

A handful of the world’s coral reefs are actually thriving

A handful of the world’s coral reefs are actually thriving

Coral reefs seem to be having a bad century, with global bleaching events and the Great Barrier Reef fading away before our eyes.

But there’s a bright spot, folks! Actually, there are 15 of them, according to a new study published in Nature.

A group of marine researchers has identified places where reef ecosystems are thriving despite environmental and human pressures. These “bright spots” are rays of hope for future conservation efforts, which may use them to apply better practices to less lucky places.

The study drew data from 2,500 reefs in 46 countries. The 15 reefs with unexpectedly robust fish populations were not necessarily in the most remote areas with low fishing activity. In fact, most of them included “localities where human populations and use of ecosystem resources is high,” the study notes. They are also typically found in the Pacific Ocean, in places like the Solomon Islands, Kiribati, and parts of Indonesia.

The bright spots, it turns out, tend to benefit from responsible local management and traditional customs. For example, on Papua New Guinea’s Karkar Island, locals have the right to prevent outsiders from fishing in their particular plot of ocean. They also practice a rotational fishing system where, as in farming, they leave off fishing a part of the reef to allow populations to recover.

On the flip side are the 35 “dark spots” the study identified, where fish stocks aren’t faring too well. These are places like Hawaii and Australia where locals tend to have greater access to fishing technologies — such as nets and freezers for stockpiling fish — that aid and abet intensive exploitation. Dark spots also were more likely to be suffering from recent environmental shocks, like bleaching.

Experts hope to use the bright spots as blueprints for more creative conservation efforts.

“We believe that the bright spots offer hope and some solutions that can be applied more broadly across the world’s coral reefs,” says Josh Cinner, the lead author on the study. “Specifically, investments that foster local involvement and provide people with ownership rights can allow people to develop creative solutions that help defy expectations of reef fisheries depletion.”
