Yale e360 shares more on the value of new recording technology as it relates to conservation:
Researchers are increasingly placing microphones in forests and other ecosystems to monitor birds, insects, frogs, and other animals. As the technology advances and becomes less costly, proponents argue, bioacoustics is poised to become an important remote-sensing tool for conservation.
Mitch Aide, a tropical ecologist based in Puerto Rico, thinks we should listen to the earth a lot more than we do now — and not just listen to it, but record and store its sounds on a massive scale. His aims are not spiritual, but scientific: He, his colleagues, and other experts are developing and deploying audio recorders, data transmission systems, and new artificial intelligence software that together are rapidly expanding scientists’ ability to understand ecosystems by listening to them.
Today, Aide can nail a cheap digital audio recorder to a tree in Puerto Rico’s Luquillo Forest and transmit its recordings to a computer running prototype software, which indicates almost in real time whether any of 25 species of frogs and birds are vocalizing in the forest. The system’s apparent simplicity belies its power – Aide thinks that it and similar systems will allow scientists to monitor ecosystems in ways we can’t yet imagine.
He dreams that one day soon, audio recordings of natural soundscapes will be like rainfall and temperature data, collected from a worldwide network of permanent stations, widely available for analysis, and permanently archived. Each clip will be “like a museum specimen,” he said, “but containing many species.” Aide says scientists will be able to efficiently determine how species are moving or changing in response to global warming, habitat destruction, or human disturbance, and chart population shifts over large areas.

No one is immune to the charisma of small owls, as far as we know. And that charisma would explain how the volunteers working to band this bird got catalyzed. Thanks to the Lab of Ornithology and this article from the current issue of Living Bird magazine:

There is something wonderful about an autumn night; the sharp bite to the air, the rustle of a north wind in the last leaves clinging to the tops of the oaks, Orion shining in a moonless sky over the central Appalachian ridges of Pennsylvania—and echoing over it all, a repetitive, mechanical beep that reminds most people of the warning alarm when a garbage truck is backing up.

When I last worked as a waiter we served espresso from a small machine that could draw a single demitasse serving. The machine, from France, used proprietary mesh pods, a precursor to capsules. I had no opinion in the early 1980s about any environmental issues with pods, but I did have an opinion, thanks to my French colleagues, that the espresso the machine produced was perfect. These days I do not drink espresso often. I believe a brewed arabica is a better beverage both gastronomically and ecologically. I have also developed an opinion about the ecological problem with single-serve technology, and I remain skeptical even as I read a headline like this:
Lavazza launch comes amid rising concern over where 20bn single-serve plastic pods end up
The first compostable one-cup coffee pods from a major manufacturer will go on sale this week in a battle to stop the 20bn pods used every year around the world from ending up in landfill. Continue reading
During June and July last year we were in residence on a dairy farm, and the prospective benefit of cows having seaweed added to their diet came to my attention. Today another briefing on this topic, from Rowan Walrath writing in Mother Jones, notifies me that this idea is making progress:
One day in January 2014, police rushed to a farm in Rasdorf, Germany, after flames burst from a barn. They soon discovered that static electricity had caused entrapped methane from the flatulence and manure of 90 dairy cows to explode.
Headline writers had a field day. But the incident pointed to a serious problem: Ruminant livestock, mostly cattle, account for 30 percent of all global methane emissions, pumping out 3 gigatons of the gas every year in their burps, farts, and manure. Methane is an especially potent greenhouse gas: During its 12-year lifespan after being released, it traps 84 times as much heat as carbon dioxide, and its effect on global warming over a century is 34 times that of CO2. According to the United Nations, reducing methane emissions from cows could be one of the quickest ways to slow climate change. Continue reading
Creek beds are bone dry and once-gushing springs are reduced to trickles as fights play out around the nation over control of nation’s freshwater supply
The network of clear streams comprising California’s Strawberry Creek run down the side of a steep, rocky mountain in a national forest two hours east of Los Angeles. Last year Nestlé siphoned 45m gallons of pristine spring water from the creek and bottled it under the Arrowhead Water label.
Though it’s on federal land, the Swiss bottled water giant paid the US Forest Service and state practically nothing, and it profited handsomely: Nestlé Waters’ 2018 worldwide sales exceeded $7.8bn. Continue reading
In the photo above, the view is from our home up to the home of a friend who grows coffee in the upper reaches of Escazu. He is an agronomist whose foremost specialty is bananas, which he has helped farmers grow more effectively throughout Latin America. I mentioned his coffee at the start of this year when we were meeting farmers, chocolatiers, and local artisans, knowing we would launch Authentica, and its sibling venture Organikos sometime this year.
We ended up not choosing that particular coffee as one of our 12 offerings, but every tasting, every artisan meeting, every event we have attended to find things that offer “taste of place” and that look and feel like the essence of Costa Rica–all have been helpful in establishing our product line.
Escazu, where we live, where the idea for Authentica started and also where Organikos is situated is an ideal location for what we do. The festival of masks, organized by the community, is an example of why: local pride, sense of place, sharing with others.
She is a scientist who explains in language I understand, without dumbing it down too much, something as complex as climate change and its relationship to global warming. She is also funny. I found the blog post above after listening to her on this podcast, just to double check that she is consistently clear, profound and funny. She will be responsible for my staying tuned to this series:
Heroes who made it happen, and here is a bit of the story, thanks to Sierra Club:
Tompkins Conservation donations are the largest act of wildlands philanthropy in history
THE MINISTER of public lands was about to arrive, a television crew in tow, so everything had to be just right. It was 8:15 on a summer morning in February, and the office of Tompkins Conservation outside the Chilean hamlet of El Amarillo was hive-busy. The philanthropy’s controller was hunched over a laptop filled with spreadsheets. A supervisor was giving orders to groups of men in blue coveralls. Kristine McDivitt Tompkins, the organization’s president, sat at a conference table toggling between a pair of laptops and her cellphone. Continue reading

Women’s photography of greater sea snake, once believed to be an anomaly in the Baie des Citrons, help scientists understand the ecosystem
A group of snorkelling grandmothers who swim up to 3km five days a week have uncovered a large population of venomous sea snakes in a bay in Noumea where scientists once believed they were rare.
Dr Claire Goiran from the University of New Caledonia and Professor Rick Shine from Australia’s Macquarie University were studying a small harmless species known as the turtle‐headed sea snake located in the Baie des Citrons, but would occasionally encounter the 1.5 metre-long venomous greater sea snake, also known as the olive-headed sea snake.
Goiran and Shine believed the greater sea snake was an anomaly in the popular swimming bay as it had only been spotted about six times over 15 years. From 2013, they decided to take a closer look at the greater sea snake to better understand its importance to the bay’s ecosystem.
“The study zone is in the most touristic bay in Noumea, so I often meet people when I am doing field work on sea snakes,” Goiran said. “When I was snorkelling on my own studying sea snakes, I used to meet a friend of mine called Aline that was snorkelling and taking photos on the same reef. In order to help me, she started taking photos of sea snakes and would send them to me by mail.
“I was very happy, so she asked her neighbour and friend Monique to help me too. Monique asked another friend, and soon there were seven grandmothers helping me.” The group named themselves “the fantastic grandmothers” and range in age from 60 to 75. Continue reading
Today, good news from New York City resulting from some extended bad news. Instead of putting the headline and the photo from the news story (tragedy), we have placed the video above to digest before reading the news below:
Riding a bicycle in New York City is often a harrowing journey across a patchwork of bike lanes that leave cyclists vulnerable to cars. The dangers came into focus this year after 25 cyclists were killed on city streets — the highest toll in two decades.
Now Mayor Bill de Blasio and the City Council have agreed on a $1.7 billion plan that would sharply expand the number of protected bike lanes as part of a sweeping effort to transform the city’s streetscape and make it less perilous for bikers.
Its chief proponent, Corey Johnson, the City Council speaker, calls it nothing less than an effort to “break the car culture.’’
Such ambitions show how far New York has come since around 2007 when the city, under Mayor Michael R. Bloomberg, started aggressively taking away space for cars by rolling out bike lanes and pedestrian plazas. Continue reading
