Craters Of Man’s Devotion

StG Ethiopia

Some snapshots of my Ethiopian expedition, just ended, are in order; not of the national parks which were the main purpose of the expedition–more on which later–but from the visit to the north which is where most visitors to Ethiopia currently make a sort of pilgrimage for reasons you can understand looking at these snapshots.

It would be difficult for any photo to do justice to this wonder, a church created by men 1,000 years ago by carving down into the stone mountain. But words are even less helpful for reasons you can probably best understand by seeing another view of the same, following what the UNESCO World Heritage Centre has to say about this and the other churches of Lalibela, Ethiopia:

…The churches were not constructed in a traditional way but rather were hewn from the living rock of monolithic blocks. These blocks were further chiselled out, forming doors, windows, columns, various floors, roofs etc. This gigantic work was further completed with an extensive system of drainage ditches, trenches and ceremonial passages, some with openings to hermit caves and catacombs…

As impressive as those craters in Siberia may be, they pale compared to what man can do when he is sufficiently motivated, which may be the one source of hope for addressing the challenges of climate change (one of the seemingly impossible challenges of our own time). This modern challenge, now that I think of it, seems particularly well-suited to the beliefs many hold, across various religious traditions, about the saint who is the namesake of this particular church.

Understanding Climate Change Through Craters

/ Organikos / 2 Comments

The jury is no longer out on how climate change has been influenced by man, since the dawn of the Industrial Revolution and especially in the last 70 years. But the jury has not even convened yet on many phenomena in the natural world, including some geological oddities. Thanks to National Geographic‘s news service for this story from the far reaches of Siberia:

New Theory Behind Dozens of Craters Found in Siberia

Scientists narrow down the cause and think it is related to warming.

When a massive and mysterious hole was discovered in Siberia last July (see pictures), social media users pointed to everything from a meteorite to a stray missile to aliens to the Bermuda Triangle as possible causes. But the most plausible explanation seemed to be the explosive release of melting methane hydrate—an ice-like material frozen in the Arctic ground—thanks to global warming.

A joint expedition made up of two Zaina Lodge and two of our team members just concluded two weeks in Ethiopia sampling the best national parks, scouting for new locations in which to collaborate, and tasting foodways evolved over millennia. The Zaina duo at this moment are headed back to Ghana, and we can imagine they will appreciate this:

Libraries of Life

At Raxa Collective we’ve always been big admirers of museums, whether focussed on art, culture, or nature. In today’s op-ed section of the New York Times, two biologists write about the importance of natural history museums. The authors, Larry M. Page and Nathan K. Lujan, argue that funding shouldn’t be cut from these types of institutions and that the active collection of specimens from the wild should not be curtailed:

These specimen collections serve as the bedrock of our system of taxonomy — the rules by which we classify life — and are integral to our understanding of the threats, origins and interrelationships of biodiversity. And yet, thanks to budget cutbacks, misplaced ethical critiques, public misconceptions and government regulations that restrict scientists while failing to restrict environmental exploitation, the continued maintenance and growth of these libraries is in danger.

Though most visitors never know they are there, natural history collections are as critical to modern biologists as libraries are to journalists and historians. Indeed, like good literature, each museum specimen allows reinterpretation by every person who examines it.

A couple of our contributors–myself included–are currently working for the Smithsonian Institution, and our supervisor is the curator of birds Continue reading →

5 things you might not know about the science of coffee

/ Derek Spier / 1 Comment

wake-up-and-smell-the-coffeeIf you are like me, you are obsessed with your coffee. I love the taste, the smell, the sound the grinder makes, and of course, how it makes me feel. But have you ever heard of a “coffee nap”?

Scientists work tirelessly to uncover the mysteries of the natural world, from the reasons people binge to the best way to wash hands. Recently it was revealed that they’ve figured out why coffee served in white mugs tastes so bitter. (The contrast between the color of coffee and a white mug makes the joe look and taste bolder.) Coffee served in clear glass mugs tastes sweeter. Continue reading →

Potoo Dreams

As the sun drifts below the horizon and the Jamaican bush is lit up with stars, the Northern Potoos begin to duet. QUAAAA-QUA-QUA-QUA-QUA QUA screams one into the night. Its neighbor responds in kind. As darkness settles over our tents, we fall asleep listening to their song.

Potoos are very odd birds. (This group of near passerine birds are related to frogmouths and nightjars.) During the day, they are practically impossible to spot, due to their legendary camouflage. They generally freeze at the end of a branch, and their streaky brownish and grayish plumage resembles an extension of their perch. Although we checked many snags while in Jamaica, we could never find a potoo in the daytime.

At night it was another story. Potoos are nocturnal, or active at night, and they like to hunt in open fields at the edge of the forest. They have huge eyes, which glow bright orange when light is shined in their direction. With headlamps, we were able to spot potoos perched on posts hundreds of feet away. Continue reading →

Menacing Weed or Wonder Plant?

We’ve written about the invasive species water hyacinth on these pages before, discussing its environmental impact as well as its material value for eco-development projects. But we haven’t seen stories such as this one from Conservation Magazine where there’s a positive side to what many people call the “weed from hell.”

The scene at Florida’s Crystal River National Wildlife Refuge in Kings Bay last October would have been familiar to anyone who has ever engaged in the battle to control the spread of invasive plants. Eager volunteers scurried about the shoreline of this manatee wintering ground, carting large plastic bins stuffed with water hyacinth, a notorious aquatic weed that’s caused headaches on five continents. Closer inspection, however, would have revealed the activity to be anything but business as usual: instead of hauling water hyacinth out of the bay, the conservationists were putting it back in—almost 4,300 gallons’ worth by day’s end.

Those volunteers were taking part in a bold pilot project that is the latest chapter in a half-century-long ecological story that reads like a fable. It starts with a well-intentioned campaign to rid Kings Bay of the water hyacinth, an aggressive nonnative species. Next come decades of additional control measures and a tragic downward spiral that transformed these crystal-clear waters into an unpleasant soup of slimy green algae. Then the story takes an unexpected turn, back to its original antagonist. Only this time, Bob Knight, the wetlands restoration ecologist leading this pioneering project, has recast water hyacinth as the unlikely hero. He believes this South American native, if controlled, could help solve the algae problem and return the bay’s ecosystem to a more desirable state. The irony in this approach is not lost on anyone involved. Continue reading →

A Sneak Peek at Jamaican Bird Videos

/ Seth Inman / Leave a comment

We have several full hours of raw bird behavior footage from our first trip, so it’ll be a while before we have much processed to the point of sharing here, but I thought it’d be nice to have a quick preview of some things to come once we’re back from our second trip to the Blue Mountains.

In the video above, you can see four relatively common bird species in Jamaica: the American Kestrel, Northern Mockingbird, Merlin, and Orangequit. The first three species can be found in the United States but have resident populations in Jamaica, while the last is endemic to the island. The behavior exhibited in the video is typical of all the species. Continue reading →

Superfoods & Taste Of Place

Several of us scouting in Ethiopia recently have been treated to roasted barley as a snack.  It has us thinking about super foods, diet, wellness, taste of place, and lots more to ponder in future blog posts; for now, this catches our eye:

The Skinny Carb

A recent study shows that people who simply ate more fiber lost about as much weight as those who went on a complicated diet.  Olga Khazan

…One reason why it’s difficult to lose weight—the most common resolution—is that dieting is so confusing.

Preparing for the Blue Mountains

/ Seth Inman / Leave a comment

A friendly caterpillar I found crawling around my tent’s rainfly on one of the last days in Jamaica.

We just finished our first week back in Ithaca, where temperatures have stayed below 0ºF most of the time and therefore we have stayed indoors most of the time. Mostly we’ve been writing up all our observations from the first expedition, digitizing our paper field notes and organizing our photos and videos; playing around with bird data in Excel, eBird, and ArcGIS (a mapping-data program); and looking at maps of the Blue and John Crow mountain ranges.

Photo by Janne Morem/Flickr. Could global warming be overcome by releasing light-reflecting chemicals into the atmosphere? With safety and efficacy at the forefront of debate, David Keith discusses the moral and political quandaries surrounding the science of geoengineering.

We have mentioned geothermal engineering on and related topics on than one occasion, but there is a more radical branch of engineering the thermal options at our disposal, with special regard to the climate change “solutions” debate. Thanks to Harvard Gazette for this informative interview on the topic:

Climate engineering: In from the cold

Keith says new reports will likely boost deeper look at geoengineering concepts

When the National Academy of Sciences (NAS) released a pair of reports this month on geoengineering, which involves deliberately intervening in the climate system to counter global warming, discussion of the controversial topic moved into the mainstream science community. The reports concluded that geoengineering is no silver bullet, and that further research is needed. Continue reading →

Green turtle links Costa Rica’s Cocos Island with Ecuador’s Galapagos

To this day, scientists have tracked three different turtles that have traveled between two of the most fragile and important island ecosystems: The Galapagos Islands in Ecuador and The Cocos Island in Costa Rica. We are just starting to understand the importance of these breeding grounds and their interconnectivity with turtle migration and reproduction.

One normal migration for turtles, one giant discovery for humankind.

With his 14-day journey from the waters of Costa Rica’s Cocos Island National Park to the Galapagos Marine Reserve in Ecuador, “Sanjay,” an endangered green sea turtle, established the first direct migration link between the two protected areas.

Sanjay was one of three green sea turtles tagged by scientists from the marine conservation groups Turtle Island Restoration Network and PRETOMA during a 10-day research expedition. Using a $4,000 satellite tag, biologists from the organizations were able to map Sanjay’s exact migration.

“It’s truly remarkable. Sanjay knew where he was headed, Continue reading →

We’re keeping an eye on the health of coral reefs in the Caribbean with the help of RAXA contributor Phil Karp, who has been writing specifically about the impact of invasive lionfish on the marine ecosystem.  In this piece for Conservation Magazine, Sarah DeWeerdt discusses the option of taking a more active role in improving the health of corals through acclimatization:

The past several decades have been tough on the world’s coral reefs. Warming waters, ocean acidification, invasive predators, and toxic runoff have hammered these iconic hotspots of underwater biodiversity.

In response, conservationists have developed coral ‘gardens’ where young corals are reared to help rebuild damaged reefs. But some scientists worry that existing restoration strategies won’t match the pace and magnitude of the threats these animals face.

In a paper published February 2 in the Proceedings of the National Academy of Sciences, biologists from the Australian Institute of Marine Science and the Hawaii Institute of Marine biology propose a more radical approach, which they call assisted evolution.

Neighbors Unite

Many of the RAXA Collective contributors could could easily get behind  the motto: “Book Lovers Unite!”; many could be found with their noses in a book from early childhood to the present day. So when we read about these “pop up libraries” in various parts of the country the only response possible was excitement.

Books are an essential part of culture and the LFL concept of sharing creates an even greater community bond worth conserving.

Three years ago, The Los Angeles Times published a feel-good story on the Little Free Library movement. The idea is simple: A book lover puts a box or shelf or crate of books in their front yard. Neighbors browse, take one, and return later with a replacement. A 76-year-old in Sherman Oaks, California, felt that his little library, roughly the size of a dollhouse, “turned strangers into friends and a sometimes-impersonal neighborhood into a community,” the reporter observed. The man knew he was onto something “when a 9-year-old boy knocked on his door one morning to say how much he liked the little library.” He went on to explain, “I met more neighbors in the first three weeks than in the previous 30 years.” Continue reading →
