Readers’ wildlife photos

January 9, 2017 • 8:00 am

Reader Tony Eales from Brisbane sent some lovely photos of models and mimics in an email called “Lycid beetle mimicry”. These beetles, in the family Lycidae, are toxic. When a tasty species (“mimic”) imitates a toxic one, it’s called Batesian mimicry. When distasteful species resemble each other, it’s called Müllerian mimicry. All readers should have learned these terms by now, and understand how such mimicry evolves (hint: it involves a predator who can either learn or has evolved to avoid a certain pattern). The pictures below show both types of mimicry. Tony’s notes are indented.

Lycid beetles or Net-Winged Beetles (Family Lycidae) must taste terrible as a large complex of mimicry has risen up around their basic look. There are even moths that mimic them. [JAC: see last picture.]

They have very interesting looking larvae. The first pic is of a larva I photographed in Borneo;  they’re commonly known as “Trilobite Beetles”  at this stage.

The next two pics are of Lycid Beetles I’ve seen here in Queensland, Australia.

The next three I think are members of the family Oedemeridae, Pollen-Eating Beetles or False-Blister Beetles. These too are distasteful to birds.

The next is a Belid Weevil, probably Rhinotia haemoptera, I’d been looking for this mimic for a while but I only managed a pretty ordinary pic before it flew off.

Next is a Yellow Soldier Beetle Chauliognathus sp.: another distasteful species.

Lastly a Longicorn Beetle in the family Cerambycidae. This is a diverse family which includes lots of mimics of wasps, ants and, in this case, lycid beetles.

JAC: And here, from Project Noah, is a tiger moth that appears to be mimicking a lycid.

The phenomenon of diverse and unrelated species mimicking either a model or each other (if they’re all noxious or toxic) is called a “mimicry ring”. (Such rings can involve both Batesian and  Müllerian mimicry). Remember that if there are several toxic species in one habitat, it’s to their evolutionary advantage to converge in appearance, for that facilitates the predator’s learning: it has to learn only one pattern to avoid instead of several, lessening the possibility of “mistakes” in which an unfamiliar pattern displayed by a toxic species is attacked and its possessor killed.

Monday: Hili dialogue (and Leon monologue)

January 9, 2017 • 7:00 am

It’s Monday, January 9, 2017, and a balmy 23° F (-5° C) in Chicago; we have some snow predicted for today. It’s also National Apricot Day (though I don’t think they’re in season), and National Cassoulet Day, celebrating one of my favorite French dishes. In India, it’s Non-Resident Indian Day, celebrating the contributions of Indians who live outside their country (imagine having a National Expats Day in the U.S!). The date was chosen because it was on this day in 1915 that Mohandas Karamchand Gandhi returned to India from South Africa.

On this day in 1349, the entire Jewish population of Basel, Switzerland, was rounded up, herded into a barn, and incinerated. They had been held responsible for the Black Death, since Jewish mortality was seen to be lower than that of non-Jews. On January 9, 1916, the Battle of Gallipoli came to an end, a great victory for the Ottoman Empire and a disaster for England, Australia, New Zealand, and France. The victorious commander was Kemal Atatürk, who later became Turkey’s President and a great force for modernization, secularization, and equal rights for women. Finally, it was on this day in 2015 that the perpetrators of the Charlie Hebdo massacre were killed, but another attack took place in a Jewish supermarket in Paris, with four hostages killed along with the Muslim attacker.

I report with sadness that Nat Hentoff (born 1925), author and jazz critic, died on Saturday. Those born on this day include Simone de Beauvoir (1908), Richard Nixon (1913), Bob Denver (1935), Joan Baez (1941), and geneticist Alec Jeffreys (1950).

Those who died on this day include Caroline Herschel (1848), the astronomer after whom Brian Cox named his cat (it’s a calico, ergo female):

Author Katherine Mansfield also died on this day in 1923. Meanwhile in Dobrzyn, Hili is demanding that her staff warm things up:

Hili: You haven’t made a fire in the fireplace.
A: I have to fetch wood from the woodshed.
Hili: Never put important duties till later!
dsc00002i
In Polish:
Hili: Nie napaliłeś w kominku.
Ja: Muszę przynieść drewno z drewutni.
Hili: Nigdy nie odkładaj ważnych obowiązków na później!

And in nearby Wloclawek, Leon is also suffering with the cold, but has turned indolence to his advantage.

Leon: I’m hatching new ideas for the icy winter.

All the cats are housebound and cold! In Winnipeg, Gus has taken over a blanket that was given to his staff, reader Taskin, who now can’t use it. Her note:

The blanket I was given for Christmas has received the coveted “Gus Seal of Approval” 🙂

Do Regressive Leftists enable the Right? A view from Canada

January 8, 2017 • 1:30 pm

Over at the CBC News site, journalist Neil Macdonald, who considers himself a liberal and has nothing but opprobrium for the likes of Donald Trump, claims that Regressive Leftism (or “Illiberal Leftism”) is shooting itself in the foot.  In his column “Advice for anxious liberals—tone down the snark,” Macdonald argues that, in Canada (and by implication, in the U.S. as well), the anti-free-speech rhetoric, hectoring, and absolute self-assurance of Leftist identity politics is turning people rightwards. I’ve gone back and forth on that, and am pretty sure that—with the exception of the excessive respect accorded to Islam by the Illiberal Left—it didn’t have much to do with electing Trump or other Republicans. But it’s still worth considering what Macdonald says, as I hate to see the Left riven by this kind of absolutist infighting. After all, we’re but twelve days away from at least four years of oppressively crazy conservatism in the U.S., and if we don’t hang together, by Heavens we’ll surely hang separately.

A few quotes from Macdonald’s piece (have a look at the two links as well):

At protests and over drinks and at dinner tables, liberals are arguing over the proper response. Some have for weeks been yelling through bullhorns that “Trump is not my president,” which is just loopy. If you’re an American, Donald Trump will be your president as of Jan. 20, and he and his elite billionaire friends will almost certainly, in the name of the common man, set about reducing the liberal china shop to a knee-high pile of crushed eggshell porcelain.

Others argue liberals must never flag, never give an inch. “We double down,” a friend defiantly declares.

Well. Certainly the rise of Trump nation, a bizarre place where anti-Semitic white supremacists comfortably cohabit with evangelical Christian conservatives and Jewish pro-Israel absolutists, is no reason for liberals to waver on values like protection of the most vulnerable among us, or helping those fleeing genocidal wars, or equality regardless of gender, sexuality or race, or curbs on the rapaciousness of unshackled capitalism.

But with all due respect to my earnest friends on the left, a bit of advice: stop being so damned irritating about it.

Particularly on campuses, the left has developed a prissy, hectoring self-righteousness, which is what happens when a bunch of people who think the same way get into the same room and congratulate one another endlessly on being right. (“Herds of independent thinkers,” as columnist and author Nat Hentoff so beautifully puts it).

Not only do they block out any opposing viewpoint, they begin to shout it down and censor it (because, you know, it’s wrong), and ultimately try to regulate it, writing rules and laws prohibiting its expression. Consult a few university speech codes — particularly those drafted by student unions — for elaboration.

To many social activists, free speech (except when it protects their speech) is just another tool of patriarchal suppression. All debate is just false equivalence.

And because any other viewpoint is patently valueless, perhaps even dangerous, they almost immediately go ad hominem, rather than engaging on the issue.

The last line is largely true, for the best weapon the Illiberal Left has is simply to call people racists, transphobes, and sexists without engaging their arguments. It’s effective because we’re all so sensitive to those slurs.

While I’m in favor of abortion on demand, and of respecting the wishes of transgender people to be called what they want (and use whatever restroom they want), there are serious discussions to be had about affirmative action, the notion of gender (feminism is being fractured that that issue), and, yes, abortion. (Consider, for instance, the flat claim that abortion is a “right”. You can’t do that without defining what you mean by the concept of “rights”.) And you simply can’t have those discussions if you begin calling your opponents names.

So while Macdonald is right to argue for ditching the ad hominems, I’m not sure how much they give succor to the right, as he claims:

But as the media repeated and amplified the story, which the media loves to do (nothing like lefty infighting to sell papers) you can bet a lot of non-urban Canadian conservatives were reading, just as they read the vicious attacks by progressives on Marie Henein, Jian Ghomeshi’s brilliant lawyer, for doing her job so well.

You can bet they’re listening closely every year at Halloween, when progressives reliably denounce as racist anyone allowing their children to dress up as a member of any other culture. Like, say, sending a little girl out dressed as Mulan.

Or when they’re denounced as Islamophobes for even discussing the question of why so many people who commit mass murder of innocents do it in the name of Allah. Or as transphobes for using the pronouns “he” or “she” without explicit permission. Or as homophobes for obeying their priest or imam. Or as some sort of uninclusive-o-phobe for uttering the phrase “Merry Christmas.”

There are millions of people out there who aren’t terribly interested in a lecture about the difference between “cisnormative” and “heteronormative,” and how both words supposedly describe something shameful.

Yes, we should stop being so damned irritating. No argument was ever won by name-calling.

University of London students demand that white philosophers be excised from curriculum

January 8, 2017 • 12:30 pm

A caveat first: this article comes from The Daily Mail, and I haven’t been able to verify it from other news sources. On the other hand, I have verified the students’ demands to which it refers (see below). Further, the Mail article gives quotes from the likes of Sir Roger Scruton, which would have to have been fabricated by the paper. Finally, you’re not going to see many pieces like this published on progressive websites or even in the “mainstream” press. So make of it what you will.

What was reported is that some students at the prestigious School of Oriental and African Studies at the University of London have demanded that the works of many famous philosophers be dropped from the curriculum—or looked at more critically—because they are white. That apparently means that those philosophers are exponents of colonialism. From the Mail:

. . . .students at a University of London college are demanding that such seminal figures as Plato, Descartes, Immanuel Kant and Bertrand Russell should be largely dropped from the curriculum simply because they are white.

These may be the names that underpin civilisation, yet the student union at the world-renowned School of Oriental and African Studies (SOAS) is insisting that when studying philosophy ‘the majority of philosophers on our courses’ should be from Africa and Asia.

The students say it is in order to ‘decolonise’ the ‘white institution’ that is their college.

Entitled ‘Decolonising SOAS: Confronting The White Institution’, the union’s statement of ‘educational priorities’ warns ‘white philosophers’ should be studied only ‘if required’, and even then their work should be taught solely from ‘a critical standpoint’: ‘For example, acknowledging the colonial context in which so-called “Enlightenment” philosophers wrote within.’

And yes, that statement does exist; it’s at the link below and this is a real excerpt (my emphasis in the text):

Decolonising SOAS: Confronting the White Institution:

Decolonising SOAS is a campaign that aims to address the structural and epistemological legacy of colonialism within our university. We believe that SOAS should take a lead on such questions given its unique history within British colonialism. In light of the centenary and SOAS’ aims of curating a vision for itself for the next 100 years, this conversation is pivotal for its future direction.

Our aims are a continuation of the campaign last year:

  1. To hold events that will engage in a wider discussion about expressions of racial and economic inequality at the university, focussing on SOAS.

  2. To address histories of erasure prevalent in the curriculum with a particular focus on SOAS’ colonial origins and present alternative ways of knowing.

  3. To interrogate SOAS’ self-image as progressive and diverse.

  4. To use the centenary year as a point of intervention to discuss how the university must move forward and demand that we, as students of colour, are involved in the curriculum review process.

  5. To review 10 first year courses, working with academics to discuss points of revamp, reform and in some cases overhaul.

  6. To make sure that the majority of the philosophers on our courses are from the Global South or it’s [sic] diaspora. SOAS’s focus is on Asia and Africa and therefore the foundations of its theories should be presented by Asian or African philosophers (or the diaspora).

  7. If white philosophers are required, then to teach their work from a critical standpoint. For example, acknowledging the colonial context in which so called “Enlightenment” philosophers wrote within.

Now they don’t give any names of white philosophers, and of course there is some justification (point 6) for including a big dollop of Asian and African philosophers (Confucius comes to mind) given that the school deals with Oriental and African studies. What’s not clear is the nature of the courses that are taught: are they general philosophy courses, for instance?

What I object to is that special criticism must be leveled at white philosophers instead of philosophers of color, as well as the assumption that what white philosophers say must always be colored by colonialism. After all, some philosophy must surely be pigmentation-free, not all philosophers were part of the Enlightenment (e.g., the ancient Greeks), and a big part of philosophy deals with questions bearing on all humans, including ethics.

Finally, these are demands, not school policy, and there’s no guarantee that they’ll be adopted.

There’s been some pushback, as reported by the Mail (again, I haven’t found these quotes independently):

Last night philosopher Sir Roger Scruton lambasted the union’s demand, saying: ‘This suggests ignorance and a determination not to overcome that ignorance. You can’t rule out a whole area of intellectual endeavour without having investigated it and clearly they haven’t investigated what they mean by white philosophy. If they think there is a colonial context from which Kant’s Critique of Pure Reason arose, I would like to hear it.’

The vice-chancellor of Buckingham University Sir Anthony Seldon said: ‘There is a real danger political correctness is getting out of control. We need to understand the world as it was and not to rewrite history as some might like it to have been.’

What we see here is that whiteness itself is taken to be a flaw, rather than particular views of white people. Are Peter Singer and John Rawls, for instance, polluted by colonialism? What bothers me the most is point 7, where the scrutiny of one’s views must be severe in inverse proportion to the darkness of their skin.  In philosophy courses it is, of course, essential to have a critical attitude, but is it not possible to evaluate the value of philosophical views without considering the ethnicity of those who propose them? And are African and Asian philosophers not going to be taught “from a critical standpoint”?

Trump advisor Monica Crowley accused of extensive plagiarism

January 8, 2017 • 10:00 am

It’s a slow news day, and that might be good since it’s been at least one day without somebody shooting up a bunch of people or running them over with a truck. (Whoops—I spoke too soon. I just learned that a Palestinian apparently drove a truck into a group of Israeli soldiers in Jerusalem this morning, killing 4 and injuring 15. A spokesman for Hamas called it “a heroic act.”)

Today’s bit of news, which seems to be reported mainly on business sites, is about Monica Crowley, former political columnist and Fox News commentator, now about to become Donald Trump’s senior director of strategic communications for the National Security Council.  That’s an important position, but, according to CNN, who broke the story, Crowley may have compromised herself with extensive plagiarism in a four-year old book.

Conservative author and television personality Monica Crowley, whom Donald Trump has tapped for a top national security communications role, plagiarized large sections of her 2012 book, a CNN KFile review has found.

The review of Crowley’s June 2012 book, “What The (Bleep) Just Happened,” found upwards of 50 examples of plagiarism from numerous sources, including the copying with minor changes of news articles, other columnists, think tanks, and Wikipedia. The New York Times bestseller, published by the HarperCollins imprint Broadside Books, contains no notes or bibliography.

The CNN Money site gives many examples of the plagiarism, along with the original sources, and it’s pretty damning. Here are a few:

screen-shot-2017-01-07-at-11-53-00-am
screen-shot-2017-01-07-at-11-54-07-am
screen-shot-2017-01-07-at-11-53-56-amscreen-shot-2017-01-07-at-11-54-07-am

According to the Washington Post, the publisher has no comment, and Trump’s people are defending her, though the passages above (and at CNN) are pretty damning.

The publisher, HarperCollins’ Broadside Books, had no comment on the CNN report.

Crowley has been named Trump’s director of communications for the White House’s National Security Council.

In response to the CNN report, a Trump transition spokesperson commended Crowley for her “exceptional insight and thoughtful work on how to turn this country around” and said that is “exactly why she will be serving in the administration.”

The Trump transition team says any attempt to discredit Crowley “is nothing more than a politically motivated attack that seeks to distract from the real issues facing this country.”

This isn’t the first time that Crowley has been accused of plagiarism. In August of 1999, she published a piece in the Wall Street Journal, “The Day Nixon said goodbye,” which had plagiarized bits from an article published 11 years earlier. Slate reported this, gave examples of the purportedly purloined prose, and was surprised to see that the accusation quickly disappeared from the news:

Four days later, the Journal ran an editor’s note that read as follows: “There are striking similarities in phraseology between “The Day Richard Nixon Said Goodbye,”  [the column doesn’t give his first name] an editorial feature Monday by Monica Crowley, and a 1988 article by Paul Johnson in Commentary magazine … Had we known of the parallels, we would not have published the article.”

Like the case of Jonah Lehrer, who was fired from The New Yorker after apparent serial plagiarism, it seems that if you’re not caught, you can just keep on doing the same thing.

What strikes me is that Crowley wasn’t caught.  I’m not sure whether book publishers have any system in place to look for plagiarism, but it’s pretty damn easy in these days of Googling. Established authors who have been vetted might not have to undergo this kind of scrutiny, but surely there should be a way to do random checks of books by first-time authors.

My guess is that Trump won’t dump her; after all, plagiarism is just a minor sin in the Trumpian panoply of malfeasance. But surely she should be discredited as an author, and HarperCollins should either retract the book or reissue it after the stolen words are purged.

A short history of this site for Cell

January 8, 2017 • 9:00 am

A while back, the molecular biology journal Cell asked several scientists who run their own websites to contribute a short precis about why they do it.  Besides me, there were Derek Lowe (In the Pipeline, a site about drugs and the pharma industry published by Science Translational Medicine), Kate Felhaber from UCLA (Knowing Neurons, a neuroscience education site), and John Timmer (science editor of Ars Technica). The pieces ran in the December 1 issue (“What Drives You to Blog?” Cell 167: 1446-1447), but aren’t free online. I’ve put a screenshot of my bit below, and will send the entire short pdf to anyone who inquires.

There’s probably nothing here you don’t know, but you may not know why I began this site eight years ago (has it been that long?) and how different it is from what I envisioned.

As of this morning, there were 44,690 subscribers. With any luck, we’ll hit 50,000 this year.

Readers’ wildlife photographs (and a video)

January 8, 2017 • 7:45 am

Reader Joe Dickinson has another set of photos from a recent trip to Africa; his notes are indented.

Here’s another set from Tanzania.  The Ngorongoro caldera is another site with year-round water (from the surrounding highlands), so it has resident populations that do not migrate.

Cape buffalo (Syncerus caffer) often move between the highlands and the caldera, so we encountered them mostly on the slopes coming down from the rim, either in mixed herds or in small groups of bulls.
