Beetle Byte (28 October 2014 edition)

“Ancient” data; ancient DNA; zombies; other algae-covered creatures… and more.

 

“Ancient” satellite images

ā€˜All of itā€™ turned out to be 25 boxes full of tins containing several thousand 60-metre rolls of photos, and quickly-deteriorating magnetic film with infrared imagery ā€“ unopened, and labeled with useless information on orbit numbers rather than locations. But the prize was too great, and he was running out of time: with the surviving NASA scientists who had taken the original images well into their 80s, he knew it wasnā€™t long before the knowledge he needed to decipher the data would be gone forever.

 

It makes sense to be slothful

Slowness is the ultimate weapon in an evolutionary war against eagle-eyed, fleet-footed predators. What better way to blend in with the forest than to cosy up with algae and fungi. Ritual defecation is the sloth equivalent of speed dating, just without the speed.

 

Sickening

This morning, our friend Rebecca at Calipidder alerted us via a Facebook post to a woman named Casey Nocket who had traveled to the west coast from New York for a few weeks. Ms. Nocket had been enjoying her time in the outdoors so much that she decided to document her trip on Instagram. And apparently Nocket was so moved by all the natural beauty she saw that she just had to paint all over it.

 

Fossil forest… in a mine

But it was a different thing entirely when John Nelson and Scott Elrick, geologists with the Illinois State Geological Survey, examined the Riola and Vermilion Grove coal mines in eastern Illinois. Etched into ceilings of the mine shafts is the largest intact fossil forest ever seenā€”at least four square miles of tropical wilderness preserved 307 million years ago. That’s when an earthquake suddenly lowered the swamp 15 to 30 feet and mud and sand rushed in, covering everything with sediment and killing trees and other plants. “It must have happened in a matter of weeks,” says Elrick. “What we see here is the death of a peat swamp, a moment in geologic time frozen by an accident of nature.”

 

In time for Hallowe’en… zombie corals

Last year, marine biologist Peter Mumby took a dive into the Rangiroa lagoon, in French Polynesia. What he saw shocked him so much he thought he might be lost.Heā€™d expected to be surrounded by death, by a reef of dying coral whose skeletons were slowly crumbling into the sea. Instead, majestic, olive-green Porites corals, the size of large hippos, carpeted the sea floor, providing a playground for parrotfishes and the occasional shark that weaved between the cauliflower-shaped giants.

 

You won’t catch me doing this

The 57-year-old leapt out in a specially-designed space suit, reaching speeds of more than 1,300km/h.Ā He exceeded the speed of sound, setting off a small sonic boom, and set several skydiving records in the process.

 

Human evolution is always fascinating

But Petraglia sees Ustā€™-Ishimā€™s genome differently. ā€œI think this is part of a population boom thatā€™s going on around 45,000 years ago, which means modern humans got to the ends of the world by 45,000 years ago,ā€ he says. Their numbers might have swamped human populations that arrived in earlier migrations.

Book review: Translations from Bark Beetle by Jody Gladding

While many people donā€™t think about it too much, insects are extraordinarily communicative animals. Perhaps this tends to escape notice because, as with most animal communication, the ā€œspeakersā€ and ā€œlistenersā€ use forms of language that are wholly unfamiliar to us. Insects use chemical pheromones, vibrations in the air (sound) and through solids and liquids, visual cues, and touch. And oftentimes, just like we do when we talk and simultaneously gesture, they will use two or more of these methods at once to transmit complex messages.

Bark beetles are no exception to this. In terms of chemical communication, they are one of the longest-studied insect groups. This is because learning how to mimic their chemical ā€œwords and sentencesā€ can also help us to control their behavior. Bark beetles are an important part of any ecosystem in which they are found, but they can also be very economically destructive. They use their chemical language to, among other things, coordinate their often-fatal mass attacks on trees so that they can mate and their larvae can eat the treeā€™s tissues. Much of the research into bark beetle pheromone communication has been done with at least a background objective of developing new and better control methods. That is, if we can figure out how the insects are communicating with each other, we can send them false messages to lure them into traps, force them away from trees, or at least monitor their presence or absence in a forest or city park.

Bark beetles also ā€œcommunicateā€ with researchers. One of the best things about working with this group of insects is that once they attack a tree, the parents and then the hatched brood etch their marks on the wood of the tree as they mine through the tissues just under the bark. The under-the-bark patterns of bark beetle galleries are about as diverse as the number of bark beetle species. In general terms, one or both of the parents excavate a main gallery, the female lays eggs on the walls of that tunnel, and then the hatched larvae bore outwards from the parental gallery. This means that an interested observer can strip back the bark of a tree ā€“ whether attacked recently or in the rather distant past ā€“ and can measure the length of the parental gallery and the length and number of the larval galleries. These measurements and counts give information on the number of eggs laid, the number of larvae hatched, and the success of the larvae among other things.

In other words, the beetles etch their story onto the wood, and we can read these ā€œmessagesā€ as well as we can read a book.

Of course this isnā€™t real communication, per se, because the insects are not really passing a message on to the observerā€¦ or are they? Do the insects have something to say to us? What are they (collective) saying? These are questions Jody Gladding implicitly asks in her volume of poetry entitled ā€œTranslations from Bark Beetleā€.

The cover of this book is the first thing that grabs the viewer ā€“ perhaps particularly if the viewer is an entomologist (click the thumbnail above to enlarge). The cover features pinned adult specimens of Hylurgopinus rufipes (a.k.a. the native elm bark beetle or the american elm bark beetle) and Scolytus multistriatus (a.k.a., the European elm bark beetle) along with an example of a bark beetle gallery etching. And this visual is the first poetic feature of the book. Here we see, juxtaposed, two insects that infest elms, but one that is supposed to be in North America sitting next to one that should never have arrived on our shores. The native elm bark beetle is a part of the system. While it can be destructive from a human perspective, it does what it has always done where it has always done it. The European elm bark beetle, on the other hand, is not supposed to be here, is not a natural component of the North American ecosystem, and is, if anything, even more destructive than its native cousin. The coverā€™s visual poetics, then, reveal that what we see as ā€œnaturalā€ or ā€œunnaturalā€ (or ā€œartificialā€) may in fact have overtly similar symptoms, but that the deep reality differs in ways that matter.

And it is this deep reality that Gladding seeks throughout this volume. Bark beetle translations bookend this volume with a variety of other poems in between. In each case of bark beetle translation Gladding includes a rubbing of a gallery system and then provides the translation of the beetle-collective poetry. Gladding provides some indication of how she went about the translation, including this:

Certain elements of the grammar make translating Bark Beetle problematic. There are only two verb tenses: the cyclical and the radiant. Prepositional phrases figure prominently and seem necessary for a complete syntactical unit. The same pronoun form (indicated as ā€¢) is used for the first and second person in singular, plural, and all cases.

It is difficult ā€“ impossible, actually ā€“ to recreate any examples of the bark beetle poetry sufficiently in a blog format as the lineation necessarily follows the organized-but-chaotic shapes of the galleries. Certain sections stand out on their own, however, including this one from ā€œEngraver Beetle Cycleā€:

ā€¢ think ā€¢ā€™m repeating mā€¢yself/there are rumors of flight and fungi/(of light and lying)/the death of a treeā€™s

ā€œ(R)umors of flight and fungiā€ā€¦ exactly what one might expect the yet-to-metamorphose larval collective under the bark to consider. This presents us with the question of what we (plural) contemplate in our (plural) larval stage, for ours is a continual procession of metamorphoses, whether we are willing to recognize that fact or not.

Ultimately the best way to appreciate the poems in their entirety along with the accompanying rubbings ā€“ besides buying the book, which I highly recommend you do ā€“ would be to take a look at a sample of the poetry linked at this page at Milkweed Editions. That short sample exemplifies the physical-natural aspect of Gladdingā€™s poetry. In other instances she creates poems on objects ā€“ natural and artificial ā€“ ranging from eggs to tongue depressors to slate to change-of-address forms. This interplay between natural and artificial is a theme throughout the volume.

Some, maybe many, of poems seem playful on first glance ā€“ for instance ā€œquarryingā€ poems from Robert Frost Ā ā€“ but contain a poignant, serious depth that is apparent with close contemplation. While this entire volume could be read in one sitting, each piece could, and should, be chewed and digested slowly, slowly. To riff on the natural/artificial divide, this volume is not a Big Mac that you devour in a rush. Rather it is a hearty soup and fresh bread eaten alongside conversation with good friends and a bottle of fine wine.

I will close by pointing to one of my favorite poems in this excellent collection. In ā€œLook Inside to See if Youā€™ve Wonā€ Gladding shines a glaring light on the uncaring effect of human artifice on the natural. Describing blundering cars, big box stores, and fast food in the midst of a flight of butterflies being crushed on radiator grilles she writes:

Ā  Ā  Ā  Ā  Ā  Ā  Ā  Ā  Ā  Ā  Ā  Ā  The butterflies were not trying to tell us
anything and anyway we wouldnā€™t have noticed. It was
such a pretty drive.

If you think that short passage stings, buy the book, slowly chew that whole poem as a bark beetle would work its way through the tissues of a tree. And then go on to digest the rest of them. Slowly, slowly.

Porcupines? Spiders? Canadian inside baseball politics stuff? Yes!

 

Ok, here’s the porcupine (video)

Pumpkin, pumpkin, and more pumpkin! What respectable porcupine could resist this Halloween feast?

 

So, about that big spider

For some reason, probably related to the proximity of Halloween, my blog post about the Goliath birdeater spider received an inordinate amount of attention, and has been republished, reinterpreted, outright stolen, and vilified all over the Internet. This one post on my obscure blog is now receiving in excess of 120,000 unique visits every day, and comments are pouring in. Alas, most of them are somewhat less than positive, and I am beginning to wonder if I really am a ā€œHORRIBLE personā€ who ā€œwill destroy the earth.ā€ (I must admit that some of the trolls were touchingly tactful ā€“ they might have said ā€ F&*K you, a$$holeā€, but they modified the foul words as not to offend my sensibility.) But why the vitriol?

 

Trust me on this: Canadian politics are interesting

Forty-seven years ago, perhaps in the outsized spirit of Expo 67, the retired major general and author Richard Rohmer put forward a bold proposal inĀ Mid-Canada Development Corridor: A Concept. It described a vast landmass stretching from Newfoundland and Labrador across Quebec, Ontario, and the Prairies, to British Columbia and up through Northwest Territories and Yukon, occupying the area between southern settlements and the treelineā€”a band dominated by boreal forest. His idea was to implement a national strategy to develop and populate it.

 

Anti-vaccine politics

What about those red states? Texas does have a lack of peopleĀ being vaccinated, but defenders of anti-vaccine progressives are choosing to skew the statistics there. We want to think about people exempting their kids, not to try and claim that poor people whose children did not get a Hep B vaccine at 19 months of age is the same as Jenny McCarthy. Legitimate medical exemptions are why we want herd immunity for people will immune issues and Texas leads in those. California, on the other hand, has 8X as many ‘philosophical’ exemptions as Texas has medical ones. There is a big difference between a school-age child whose parents have chosen not to get a vaccine and an illegal immigrant or a poor person who cannot afford it.

Conservation basic training

Iā€™m always a good several months behind in reading my National Geographic subscription. Recently I was working my way through the August 2014 issue and got to a fantastic article (I canā€™t remember very many National Geographic articles that arenā€™t fantastic) about Franz Josef Land ā€“ an isolated archipelago in Russiaā€™s region of the Arctic Circle.

I enjoyed the entire article, of course. But a particular quote that caught me quite off guard and has caused me to ruminate for the past few days. Digesting that glossy cellulose can be difficult for gut microbes. Hereā€™s what I read:

(National Geographic Explorer-in-Residence Enric Sala) was a professor at the Scripps Institution of Oceanography, teaching grad students about food webs and marine conservation but dissatisfied with his contribution to the world. ā€œI saw myself as refining the obituary of nature, with increased precision,ā€ he tells me during a conversation aboard the Polaris. His distress at the continuing trends of ecosystem degradation and species loss, in marine as well as terrestrial realms, led him out of academia. ā€œI wanted to try to fix the problem,ā€ he says. So in 2005 he assembled a SWAT team of scientists, including experts on marine microbes, algae, invertebrates, and fish, and sailed for the northern Line Islands, a remote cluster of coral outcrops in the Pacific about a thousand nautical miles south of Hawaii.

Oftentimes there is a disconnect somewhere between what a person thinks, what they say, what a journalist thinks they said, what an editor decides, and what ends up being printed on paper. Iā€™ve experienced that, as has anyone who has been interviewed by the media for just about anything. So Iā€™ll give Dr. Sala the benefit of the doubt here, but will comment on the way that this has been presented by National Geographic.

The implication in this clip of text, intentional or not, is that the job of teaching biology and natural history is task that does not have important conservation implications. I beg to differ.

In fact, I would argue that teaching is at least as important as data collection. Yes, there are the more obvious conservation roles that are more easily noticed than a professor in front of a lecture hall or guiding a group in the field or the lab. These include conservation officers, engaged politicians, park rangers, environment/agriculture/forestry/parks ministry employees, thoughtful farmers and foresters, academic/industry/government scientists, environmental consultants, NGO employees, public health nurses and physicians, and National Geographic Explorers-in-Residence. Those individuals are analogous to the soldiers fighting the battle on the front lines. But, as with any army, those front line soldiers would not do well if they were just dumped in front of the enemy with a loaded rifle and a “good luck.”

Winning battles, and ultimately winning a war, requires that soldiers be trained. Trained to operate independently. Trained to work in teams. Trained to understand the terrain. Trained to work with the equipment. Trained to get results. Academic teaching done correctly and enthusiastically ā€“ and with a focus on natural history and conservation ā€“ is a vital part of the basic training that conservation professions require in order for efficacy. Dr. Sala is undoubtedly the engaged conservationist and excellent scientist that he is in some very large part due to that basic training in an academic setting.

Beyond that, those of us who collect and synthesize data have not done our jobs completely if we do not also bring those results and their implications to a wider scientific and lay public. By participating in this National Geographic feature (indeed, by working for National Geographic) Dr. Sala has simply exchanged his teaching role from a classroom to the pages of a magazine. When we conduct research and then present it at a conference, in a scientific paper, in a classroom or field course, in a textbook, in a magazine, or on a radio or television program, we are teaching. Teaching, in whatever context, goes hand-in-hand with the scientific endeavor. I am taught when I read a colleagueā€™s paper, even if I am reading her paper decades after she wrote it. She wrote it to teach me and others about phenomena that she had observed. When I take what I have learned from her study into the classroom and present it well, my students, I would hope, are better off for it and are better prepared as engaged conservationists as they prepare to work to protect habitats, species, ecosystems, and societies.

There is no doubt that the work of conservation in the face of massive, global anthropogenic influence is a vital and growing concern. Looking at the data, it sure seems that we are too often losing important battles. Dr. Sala is correct to be concerned about being caught up in ā€œā€¦refining the obituary of natureā€¦ā€ But the best way to stop writing that obituary is to bring the wonder and amazement and necessity of our natural world into the metaphorical “classroom” by bringing relevant research results (our own and those of others) to students. This is one of the best ways to create authentic, engaged, and active young conservationists who will fill traditional conservation roles or who will be conservation vocationists and ambassadors in whatever profession they ultimately choose.

Teaching is the hard and often unnoticed basic training work of conservation. And thatā€™s why I choose to do it.

Time to say good-bye to the tumbling tumbleweed

Dana Berner wants to start an epidemic among tumbleweeds. Berner is a pathologist with the U.S. Agricultural Research Service who studies the diseases that afflict plants. One of his projects has been a search for something that’s able to infect and kill the iconic, spiny, rolling weed of the American West.

 

Take a look at this beautiful creature

When threatened, P. wahlbergii exhibits deimatic behavior, a threatening and startling response intended to discourage predators. Ā The mantis spreads out its body, raises its forelimbs, and opens its magnificent wings to expose patterns which resemble two large eyes.

 

12 tips for talking to science faculty about new teaching strategies (by Terry McGlynn)

Donā€™t push technology as a solution to a pedagogical challenge. Weā€™d like to see what works, but not to have it marketed to us. (For example, tell us about clickers. But donā€™t claim that they make students learn better, because they donā€™t. They promote active learning, problem-solving and reflection, which causes learning. Scientists dislike false claims that often accompany technological promises.)

 

North Korea’s “Winston Smith”

Because Jang was required to write in a foreign style, he was one of the few people in the country permitted to read South Korean newspapers. Jang was shocked to learn that everything heā€™d learned as a child was a lie ā€” and that South Korea was a thriving democracy many times more rich than its northern counterpart. More shocking still, he learned, writers in South Korean newspapers were permitted to criticize the government, a capital offense in North Korea. (In fact, everything in North Korea is a capital offense, as a sampling of public posters described in the book attests: ā€œDeath by Firing Squad to Those Who Disobey Traffic Rules!ā€ ā€œDeath by Firing Squad to Those Who Waste Electricity!ā€ ā€œDeath by Firing Squad To Those Who Gossip!ā€)

 

A great primer on the poetic line

If you want to understand poetry, and maybe learn how to write it, you definitely want to learn about the different kinds of poetic lines and the uses of line breaks in poetry. The more poetry you read, the more youā€™ll notice some poets use short lines, some use long, some set all the lines on the left side of the page, and some indent lines differently all over the page. The relationship between the poetic line (including its length and positioning and how it fits into other lines) and the content of a poem is a major aspect of poetry. Some critics go so far as to say that lineation is the defining characteristic of poetry, and many would say itā€™s certainly one major difference between most poetry and prose.
