Fossil Dung Balls

Once again, very busy, but I had to write this, just for the post title.  From a news release:

“A new study of 30-million-year-old-fossil ‘mega-dung’ from extinct giant South American mammals, published in Palaeontology, reveals evidence of complex ecological interactions and theft of dung-beetles’ food stores by other animals….

Some 30 million years ago, the continent was home to what is known to palaeontologists as the South America Megafauna, including some truly giant extinct herbivores: bone covered armadillos the size of a small car, ground sloths 6 metres tall and elephant-sized hoofed-mammals unlike anything alive today. And of course, megafauna would have produced mega-dung.”

Yes. Mega-dung.  I love science.

The paper itself is actually about the activities of kleptoparasites, which, as you might infer from the name, is parasitism by theft. In other words, one animal steals prey (turds) from another animal (dung beetles) and uses it for its own purposes. In this case, flies and other dung beetles were the thieves; earthworms seem to have also found fertile grounds in the dung balls as well.

Oh, what are the dung balls for? You’ve probably seen the videos–the beetles harvest dung pies for a nice little food source to lay eggs on.  The narration on this video is a bit twee, but the video is very nice:

Goodbye my Lovely (garden)

I’m going to be super busy this week with a huge project at work–and then I have to move.

We finally did get an offer on our house, but it’s contingent on our being out of the house by July 30th. So, I am a bit frantic trying to manage both packing and work.

It is also hard to leave a garden that I’ve been tweaking for over 6 years, and that is really at it’s peak this time of year.

I’ve got a mixture of native prairie plants and some prettier exotics to keep something in bloom as early as possible. It’s also frustrating that all the tomatoes and other veggies I planted this year haven’t really started to set fruit because of the cold summer we’re having.  (I do have a lot of peas, though!)

I will miss my house, but I also am relieved to not be driving across the state every morning and night. I will definitely miss all the money I threw into it and that is gone forever too, but mostly….

Goodbye my lovely house and garden.

:(

Everyone keep your fingers/tentacles/ whatever crossed and hope there’s no more unexpected problems before closing!

Baldwin and Bot Flies

Because, as busy as I am, I can always stop and bring you news of a celebrity-insect nexus.

I don’t watch much TV–and so I REALLY had no plans to watch “I’m a Celebrity, Get Me Out of Here!” (although if Rob Blagojevich had been on, that might have been worth it, just to see what would happen to his hair.)

And yet:

Steven Baldwin Quits Celebrity Show after Botflies get Under His Skin

“Baldwin said: “I suffered in the first eight days of production, while in the jungle, over 125 insect bites on my body… kind of all over and two of them, much to my surprise, became quite lumpy initially.

“Within about 72 hours they were these half dollar-sized lumps under my skin that were probably about an inch thick….. I did get to take some time with the medic who explained that in his opinion at that point he didn’t think that it was the ‘implantation of insect larvae into my flesh’, but that – oh gosh – that’s what it could be… So they tested these things and sure enough, Stevie B was ‘pregnant.

And therein lies perhaps the most interesting thing you’ve ever read about Stephen Baldwin.’”

I’ve covered Bot Flies before here at the Bug Blog, and generally they are uncomfortable, but not usually very dangerous. In one of the best opening sentences of a scholarly paper ever, Paul Catts wrote:

“Maggots of cuterebrid bot flies are conspicuous, repulsive, and frequently encountered cutaneous parasites of Mammals in the New World.”

Yep, that’s about right. The primate bot fly belongs to the Genus Dermatobia, in the fly Family Oestridae. This family of flies are also known as warble flies, and infest all manner of mammals, including horses, cats, and mice.

Migratory Butterfly Research in Europe

I’m still super busy, so how about you visit LabLit and read about the amazing migration of the Painted Lady Butterfly.  The article is written by a researcher that is putting the butterflies into a flight simulator (!) to determine how they orient.  In other words, how do they know in which direction to fly?

The Painted Lady migrates from Africa all the way to Britain and northern Europe.  I suspect Nesbit’s work is related to further elaboration on this recent paper, that described two layers of migration: One at the ground level, relatively independent of wind movement, and another at very high altitudes, where prevailing winds would move the butterflies without much effort very great distances.

Nesbit works in the Chapman lab, which has done a great deal of work on butterfly migration.

Brain Droppings

Can I just say, I really, really miss George Carlin?  Anyway:  a roundup of random items and a vote!

Item 1: Finally, after 2 years, we have an offer on the house!! We also did have to re-dig our water well…and repair the septic tank…but it does seem like it will happen.  The downside to this is that the offer is contingent on our moving by July 30th.  EEEEK!

Item 2: I will be super busy the next two weeks with a major new program for first-year students, as well as getting our fall classes sorted out. So, posting will be very spotty.  I feel bad about phoning it in on the Bug Blog so often lately, but life is pretty crazy.  You can tell I’m stressed because I’ve cut most of my hair off.

Item 3: Because I will be working 24/7 for the next couple of weeks, I’m trying to start packing now. Here’s the vote: Keep the 1979 high school year book? or chuck it?

Congrats Becca and Sid!!

In case you missed it–Rebecca and Sid got married at TAM.  So bummed I couldn’t be there, but so happy I could see it on JREFmedia stream!! :D

In case you missed it on my Twitter stream..a tribute to Michael Jackson. In Alaska. With Skeeters.

Field Biologists ROCK.  And I told you I was dressed accurately!!

Granola, Masturbation, and Michigan History

You can’t live in Michigan long without running into a building, or project, or something that is named after W.K. Kellogg, founder of the Kellogg cereal company and major philanthropist. It’s his brother, Dr. John Harvey Kellogg, who is really the interesting one, though.kellogg

Dr. Kellogg was profiled (sort of) in the book and movie The Road to Wellville. In the movie, Anthony Hopkins delivers an inspired performance of Kellogg as a…well, pretty much total nutter.

Hopkins didn’t exaggerate all that much. Dr. Kellogg was ahead of his time in terms of some of his ideas about nutrition and health. He just always managed to take them to 11 in terms of strangeness, and threw in some General Jack Ripper’s theories on pollution of our precious bodily fluids for good measure.

Dr. Kellogg’s ideas are nicely profiled in the essay “Porn Flakes.” What we know now as ubiquitous foods–graham crackers and cold flaked cereal–actually are related to fears of masturbation and religious dietary edicts.

This all begins with Sister Ellen White, founder of the Seventh Day Adventists. In the late 1860′s, Battle Creek was home to the headquarters of the Adventists, and a vision (?) inspired White to found The Western Health Reform Institute, which became known as the Battle Creek Sanitarium.  The sanitarium treated the ‘Illness’ of being a upper-class American in the late 1800′s: too much food and a sedentary lifestyle.

granoseDr. Kellogg became the manager for the Sanitarium, and advocated the principles of his church as the Road to Wellness: no meat, lots of water, and exercise.  (In fact, Kellogg could legitimately claim to have invented the aerobics class: exercise to music.  Legwarmers were not developed until later, though.)

Here is where things go odd.  It wasn’t just drinking water he pushed; Kellogg also was a major enema advocate.  One of his inventions was an enema machine that could deliver 15 gallons of water in a single sitting (so to speak).  Water enemas were followed by yogurt–half eaten, the other half delivered below.

Kellogg is profiled in the book Quack! in part because of his invention of a shaking machine.  This vibratory chair was designed to prevent constipation by, literally,  shaking the shit out of the patient.   He also invented an Electkothekapeutical Chair (that is not a typo) to stimulate your innards.  (If you really NEED to know more, you can read his 1915 book Colon Hygiene online via Google Books.)

Why did you need a squeaky clean colon?

Kellogg’s 1881 sex education book Plain Facts for Old and Young explains. Food was related to sexual desire, and and too much sex (i.e, any sex) created poor health:

” Sexual precocity, idleness, pernicious literature, abnormal sexual passions, exciting and irritating food, gluttony, sedentary employment, libidinous pictures, and many abnormal conditions of life, are potent causes in exciting the vile practice…

After long abuse of the sexual organs, and in many cases after a short course of sin, the whole system becomes deteriorated; digestion is impaired, the muscles are weakened, the circulation is unbalanced, the nerves are irritable, the brain—especially the back and lower portion of it—is congested, the skin is torpid, the bowels are inactive, the general health is deranged in almost every particular.” (emphasis mine)

In other words, sex was bad, and sex made you sick. Meat was bad, and meat made you think of sex. Sex was bad….well, you begin to see the cycle.  Granola eating and enemas were a way to purify yourself, in addition to, of course, not having any sex.

Dr. Kellogg reputedly never had sex his entire life–I’ll leave his obsession with things anal and oral for you to analyze on your own.

Some of Kellogg’s ideas for ‘curing’ the problem of sex were pretty extreme.  That would include (from the same book I quoted above) circumcision of masturbating boys without any anesthesia:

” The operation should be performed by a surgeon without administering an anesthetic, as the brief pain attending the operation will have a salutary effect upon the mind, especially if it be connected with the idea of punishment….

And..well… for women:

“In females, the author has found the application of pure carbolic acid to the clitoris an excellent means of allaying the abnormal excitement.”

Since all of you are probably clutching your groin right now, I’ll leave the story of Dr. Kellogg’s Eugenics boosterism for another time.  I just find Dr. Kellogg fascinating and disturbing.

News flash: beetles are not the same as women

Amazing. Under this headline:

“Science still cannot explain why women sleep around”

“A study published today in Science details a series of careful experiments Swedish researchers conducted on mating seed beetles (pictured). They want to find out what the benefits were to females who mated with multiple males….”

Now, as a normal person, you are probably thinking: “WTF does a paper in Science about beetles have to do with promiscuity in women?”  The answer would be NOT A GODDAMN THING.
This is one of the most blatant, shameless examples of “sexing up science” I’ve seen in a long time.

Here is the actual paper they are referring to:

Bilde, T., Foged, A., Schilling, N., & Arnqvist, G. (2009). Postmating Sexual Selection Favors Males That Sire Offspring with Low Fitness Science, 324 (5935), 1705-1706 DOI: 10.1126/science.1171675

It is a paper about seed beetles, people. Seed. Beetles.

In the press release covering this paper, there is no mention that this research means anything for mammals, much less humans. So… where did this get connected up to explaining why women “sleep around?”

In the messed up little head of the writer, that is where. Because human women liking sex is clearly deviant, and in need of explanation.

And that is how you get crazy sentences like this one:

“Why would these insects have sex with so many different men, only to choose the crappiest sperm?

As I said initially, Amazing.  Aside from the Green Porno of Isabella Rossellini, I am not aware of any human-insect hookups. (And, frankly, do not want to be aware of any, so please don’t email me.)

There are a whole host of other errors in this i09 article, and I’ll just pick this one:  It does not use the term fitness correctly.

In evolution, the one who dies with the most babies wins. Even if the animal is small, unhealthy, and wimpy.  The males with the most offspring are, by definition, the most fit.

OY.

BTW, I was asked recently to recommend some things to read critiquing evolutionary psychology, and this seems like a good spot to stick some links.
