Bats Sing Like Birds Do. Who Knew?

/ Organikos / 3 Comments

Pipistrellus nathusii, a species of European bat.

We recently learned that certain types of fruit bat can echolocate with their wings, and now we’re discovering that some bats also make sounds for reasons other than sonar or distress calls! Although bat songs have been recorded as much as four decades ago, more and more singing bat species are being found by scientists today, and these batsongs seem to function the same way that birdsongs do. As Robert Krulwich points out for NPR, there are very few types of mammal that sing, so it’s nice to see the club growing. Krulwich’s article continues below:

Bats produce “pings” or “clicks,” right? They make these high-pitched sounds, too high for us to hear, but when their cries ricochet off distant objects, the echoes tell them there’s a house over there, a tree in front of them, a moth flying over on the left. And so they “see” by echolocation. That’s their thing. They are famously good at it.

This title of the book to the left, and of the podcast interview (“Trading Pom-Poms For Field Boots”) on the National Public Radio (USA) series called “My Big Break”–and even the opening line below—give the false impression that this may be a dilettante story; but not at all. It is about discovering science in a classroom and coming to love it thanks to a deep experience in nature:

Mireya Mayor’s life plays out like an adventure film.

She’s a globe-trotting anthropologist, primatologist, wildlife expert and conservationist. As the first female wildlife correspondent for the Ultimate Explorer series on National Geographic Channel, she’s gone diving with great whites, she’s rappelled down cliffs and she was even charged by an angry silverback gorilla.

But some of her fans might be surprised by what Mayor was up to before she trekked around remote regions of the world. Continue reading →

When a writer of John Lanchester’s deep quality and broad diversity uses the word repent, we take note. This reflection on the current state of foodie-ism caught our attention a couple months ago as we were well into 51’s first season open, and preparing for the next opening, reminding us to keep it all real, in perspective. Below we excerpt what should be read from beginning to end, using the dangerous ellipsis as carefully as we can but hoping you will click over to the source:

…Once upon a time, food was about where you came from. Now, for many of us, it is about where we want to go—about who we want to be, how we choose to live. Food has always been expressive of identity, but today those identities are more flexible and fluid; they change over time, and respond to different pressures. Some aspects of this are ridiculous: the pickle craze, the báhn-mìboom, the ramps revolution, compulsory kale. Is northern Thai still hot? Has offal gone away yet? Is Copenhagen over? The intersection of food and fashion is silly, just as the intersection of fashion and anything else is silly. Underlying it, however, is that sense of food as an expression of an identity that’s defined, in some crucial sense, by conscious choice. For most people throughout history, that wasn’t true. The apparent silliness and superficiality of food fashions and trends touches on something deep: our ability to choose who we want to be. Continue reading →

We started, before even knowing the terminology, paying attention to citizen science on this blog when we began to understand the parallels with entrepreneurial conservation. And now we link to stories whenever we can that help us better understand it:

Three Generations of Citizen Science: The Incubator

Once Sam Droege gets a research project up and running, he dreams up a new one–and builds it.

BY ANDY ISAACSON

It was a bright, breezy day in late April, the flowering azaleas having finally shrugged off the winter that overstayed its welcome, when Sam Droege sailed onto the grounds of the U.S. National Arboretum in Washington, D.C., behind the wheel of a pterodactyl. It was actually a ’98 forest-green Saturn, which Droege had painted with yellow wings and a red-and-yellow beak that tapered to a point down the center of the hood. A piece of wood, lined with a rusty crosscut saw, had been bolted to the roof: the crest. Little jingle bells, inspired by richly adorned buses in Pakistan, dangled from chains screwed into the rear bumper. Droege still had designs for neon undercarriage lights, and a mosaic of mirror shards to line the car’s ceiling–“but why stop there?” he wondered. It was a work in progress.

New App for Borrowing/Lending Things

/ Organikos / Leave a comment

You can find apps for everything nowadays, and some of them are really creatively useful or simply entertaining. We’ve seen an app for typing in various indigenous languages from North America and Australia, some environmentally-focused games, the potential for a prairie dog translator app, and an application to help monitor the plants in your garden. Now we’re learning about a new company that has an app to help coordinate loans of tools or other things among neighbors. Named Peerby, this social platform came to life in the Netherlands, and seems like a great idea to promote friendly and community-building interactions while also reducing consumption. Eleanor Beardsley reports for NPR’s All Tech Considered:

Millions of people use websites and apps like Airbnb to share their homes and Uber to transport people in their cars. A new company allows people to share things like power drills and bicycle pumps by connecting people who need them to people who have them.

It isn’t surprising that the idea for the borrowing platform Peerby originated in one of the world’s most densely populated countries — The Netherlands.

Bees May Sleep to Maintain Learning Brains

/ Organikos / 2 Comments

Bees are incredibly important to much of the world’s flora, and we are always happy to see when research on them is continuing. After all, the better we understand them, the better we can protect them. Elizabeth Preston reports for Discover Magazine’s blog that when young honeybees spend time in the hive, they spend more time sleeping afterwards, probably to absorb whatever they’re learning among all the other bees:

Facing a whole hive of bees at once can be overwhelming—even for a bee. Young honeybees sleep more after spending time in the hive than after being by themselves. They need the extra nap time, it seems, to build and maintain their learning brains.

The first surprising thing about this might be that insects sleep at all. “Since around the 1980s there is good evidence that insects show…characteristics of sleep,” says Guy Bloch, who studies bee behavior at the Hebrew University of Jerusalem. Yes, their brains are tiny and organized differently from ours. But they rest in a similar way. And just as sleeping helps us sort through the new things we’ve learned each day, there’s evidence that sleep in bees and fruit flies is also tied up with memory and learning, Bloch says.

For obvious reasons, we’re big fans of trees. We’ve shared a piece on tree-sitting (which is, of course, linked to tree-hugging), and featured an environmental history essay that included some hypothetical dendrochronology. Now, we’re happy to find some amazing photographs developed in the almost lost art of painstaking platinum/palladium processing by Beth Moon.

Abbeville Press on Beth Moon’s book of photography, Ancient Trees: Portraits of Time:

Beth Moon’s fourteen-year quest to photograph ancient trees has taken her across the United States, Europe, Asia, the Middle East, and Africa. Some of her subjects grow in isolation, on remote mountainsides, private estates, or nature preserves; others maintain a proud, though often precarious, existence in the midst of civilization. All, however, share a mysterious beauty perfected by age and the power to connect us to a sense of time and nature much greater than ourselves. It is this beauty, and this power, that Moon captures in her remarkable photographs.

Counting Monarchs

Creating Breeding Habitat for Monarchs: To reverse the breeding habitat loss in the U.S., the Monarch Joint Venture promotes the inclusion of native milkweed and nectar plants in restoration efforts across the country ranging from small gardens to natural areas and corporate landscapes. (Photo by Giuseppina Croce)

We’ve seen some information on how much people value monarch butterflies. Now we’re learning that the beautiful orange lepidopterans have their own citizen science Thanksgiving count and might soon be labeled as a threatened species under the Endangered Species Act if a petition has any effect.

Beloved by tattoo parlors and fantasy princess landscapes, the king of butterflies is in decline. During their annual migration, monarch butterflies are famous for gathering in innumerable flutters as they fly from summer breeding grounds in the U.S. and Canada to warmer sites in Mexico and California. At one time, there were over a billion monarchs making this journey. Now, less than 4% are left.

Over the years, human behaviors, particularly agricultural practices have contributed to the monarch’s decline. In a petition to protect monarchs scientists point to habitat loss as grassland is converted to farmland and overwintering sites are deforested as a major factor. On top of that, the cultivation of certain genetically engineered crops enable farmers to apply broad-spectrum herbicides killing weeds such as milkweed, the monarch caterpillar’s sole food source.

We’ve featured pieces on another, less fortunate species of pigeon before, and it’s great to read news about a critically endangered species that has been making a comeback after conservation efforts. As the article by Jason Goldman for Conservation Magazine shows, however, there’s still a ways to go before the pink pigeon has fully recovered as a species:

The pink pigeon is the lone survivor of all the columbids – pigeons and doves – native to Mauritius. In 1990 the species was down to just nine individuals, but thanks to the work of the Mauritian Wildlife Foundation, there were some 400 individuals flying the skies of the island by 2013. In the year 2000, the IUCN downgraded the species from “critically endangered” to “endangered.” They’re not out of the woods yet, but their recovery remains an impressive and rare example of good news in conservation.

Kleptothermy

We’ve featured a post on biological theft before, under the name of mycocleptism. In that case the thief was a species of beetle that lived off the fungal tunnels of another beetle species, and now we are learning of a different type of behavior: stealing heat. Apparently certain reptiles, which are unable to bask in the sun at night, have found an effective method of transferring warmth that does not involve time travel. Instead, they snuggle up in the nests of birds. Brian Switek reports on the phenomenon for Nat Geo below, but one question that seems to remain unanswered is whether the feathered members of the deal are getting anything out of their reptilian visitors. For example, sea snakes like the ones mentioned in the referenced article are venomous — could it be that their presence in a shearwater nest would protect the birds from potential predators?

Imagine for a moment that you’re a sea snake and you’re feeling a little chilly. That’s quite understandable for an ectotherm. Your body temperature rises and falls with that of your environment, and spending all day slither-swimming through the water can wick away your precious body heat.

You could bask in the sun to remedy the cold. That’s a classic reptile way of working some warmth back beneath those scales. But there’s another option. You could steal your warmth. All you’d have to do is find some seabirds.

Thank you to Liz Langley from National Geographic for highlighting differences that we have always been curious about but never thought about looking into until they were laid out so clearly in a single place. And with cute photos and a couple puns to boot. The article below comes from Nat Geo’s “Weird Animal Question of the Week,” which we will be sure to visit in the future.

Hares and rabbits are in the same family, Leporidae, but they’re “different species, like sheep and goats are different species,” Steven Lukefahr, a geneticist at Texas A&M University in Kingsville, said via email.

Hares are also larger, have longer ears, and are less social than rabbits. The “most profound difference” is seen in baby hares versus baby bunnies, said Philip Stott, a wildlife ecologist at the University of Adelaide in Australia. (See National Geographic’s pictures of baby animals.)

First off, a hare’s pregnancy lasts 42 days, compared with rabbits’ 30-31 days with a bun(ny) in the oven.

Thanks to NPR we learned that Kerala isn’t the only state with a history of Plum Cakes and Fruit Cakes in late December. We love this facinating non-sectarian history!

Cake knows no religion…. Jewish bakeries and Muslim bakers in a predominantly Hindu city, baking Christmas cakes round the clock. You could call it a triumph of capitalism. Or a slice of peace and goodwill for all. With almond icing.

Thank you to the BBC’s Earth section for sharing Dutch medical physicist and artist Arie van ’t Riet’s work, which he accomplishes with his home x-ray machine and dead flora and fauna.

Arie van ’t Riet has a unique view of life on earth.

As a medical physicist based in the Netherlands, van ’t Riet teaches radiographers about radiation physics and safety. As part of his teaching program, van ’t Riet searched for an example to demonstrate and visualise the influence of x-ray energy on the contrast of an x-ray image. The higher the x-ray energy, the lower the contrast.

“I arrived at flowers. After some years I started to edit and partly colour these x-ray images. And I added animals,” he says.

We’ve featured pieces on different biofuels before, though probably not enough of them. We’ve also recently seen an example of how science can help clean up the messes that other scientifically informed — but less environmentally scrupulous — activities create, like the new carbon-scrubbing structures that might be used in coal plants. The topic of bioremediation is one of great interest and which we plan on sharing more about, especially in the mycological realm. For now we’ll start with this story of algal bioremediation and resource recuperation in Cornwall, one of England’s most historically important mining regions. Jamie Doward reports for The Guardian:

A groundbreaking research project to clean up a flooded Cornish tin mine is using algae to harvest the precious heavy metals in its toxic water, while simultaneously producing biofuel.

If the project, which is at a very early stage, is proven to work, it could have huge environmental benefits around the world.

Sloths’ and Armadillos’ Sight Stinks

/ Organikos / 1 Comment

Watching the pair of nine-banded armadillos in this video root around the forest floor looking for food, you’d think that in addition to their snuffling and sensitive noses, the armored mammals would also be using their eyes to spot scurrying insects or the white flash of a grub in the dirt. And a three-toed sloth like the one in this other video should definitely be able to scan the skies for predatory birds when it is taking care of its vulnerable young, right? Well actually, as NatGeo contributor Ed Yong reports, scientists at UC Riverside believe the genes that build color-detecting cone cells in eyes are broken in sloths, armadillos, and several other mammal species descended from the same burrowing ancestor:

Armadillos have terrible vision. In 1913, American zoologists Horatio H. Newman and J. Thomas Patterson wrote, “The eyes [of the nine-banded armadillo] are rudimentary and practically useless. If disturbed an armadillo will charge off in a straight line and is as apt to run into a tree trunk as to avoid it.”

The three-toed sloth isn’t much better. “If an infant sloth is placed five feet away from its mother on a horizontal branch at the same level, at once the young sloth begins to cry, the mother shows that she heard it calling and turns her head in all directions. Many times she looks straight in the direction of her offspring but neither sight, hearing nor smell apparently avail anything,” wrote Michel Goffart in 1971. And more comically: “Infuriated male [sloths] try to hit each other when they are still distant by more than a metre and a half.”

Australian Emissions Drop With New Carbon Tax

/ Organikos / 1 Comment

Via The Guardian

In 2012, Australia introduced a carbon tax, or carbon “price,” with the goal of reducing the country’s greenhouse gas emissions. Then, this July, the Australian government — under a different party than in 2012 — abolished the carbon tax to fulfill an election promise, since they argued that the tax was too much of a burden on homeowners and also discouraging industry. But data released this month by the Department of the Environment shows that Australia’s emissions dropped 1.4% during 2013 (the second year of the tax), which is the highest annual decrease in the country’s emissions within the last decade. Oliver Milman reports for The Guardian:

The latest greenhouse gas inventory showed emissions from the electricity sector, the industry most affected by carbon pricing, fell 4% in the year to June.

Electricity emissions account for a third of Australia’s emissions output, which stood at 542.6m tonnes in the year to June, down from 550.2m tonnes in the previous 12 months.

Emissions from transport dropped 0.4% in the year to June, with gases released by the agriculture industry decreasing by 2.6%. Industrial processes emitted 1.3% less greenhouse gas during the year, although fugitive emissions, such as those from mining, rose 5.1%.

Electricity emissions peaked in 2008 and have steadily decreased ever since, driven by a number of factors such as the winding down of parts of Australia’s manufacturing base and energy efficiency initiatives.

Finger Lakes, Just Say No

It is not a simple matter to resist all the various ways in which our natural environment is being threatened in insidious manner on a regular basis, especially proposals that appear to solve energy needs. Please, no snickering about chardonnay-sipping liberals while you read the latest such proposal in the region a number of our contributors call home, because these are actually salt of the earth farmers and craft level producers of a sacred beverage (yes, we can pour it on when properly motivated) who will suffer most if this project is implemented as proposed:

Although Organikos is a non-denominational blog, there is no doubt that Christmas is an important holiday in many of the places we work, like Kerala and Costa Rica. This year, Stephanie Pappas from the BBC shares some interesting secrets about Christmas trees that you probably didn’t know, and can read below:

Each Christmas, families gather around evergreens, real or fake, to celebrate the season.

But what holiday revellers may not realise is just how incredible these spruce, fir and pines can be.

In the wild, evergreen conifers survive drastic temperature swings, grow to towering heights and create ecosystems that shelter strange and wonderful creatures.

Here are some the secrets of Christmas trees and their tough, tenacious lives.

Christmas trees can turn to glass

Here’s a party trick not to try without the proper safety equipment: drop a sprig of Siberian spruce (Picea obovata) or Scots pine (Pinus sylvestris) in a vat of liquid nitrogen, at a temperature of -196 degrees Celsius. Providing you’ve pre-chilled the plant to -20 degrees Celsius or so, the sprig will survive.
