Readers’ wildlife photographs

June 13, 2015 • 8:45 am

Reader Christopher Moss, who lives on the north shore of Nova Scotia, sent snaps of two varieties of mammals:

I was looking through past years in LightRoom, and found a few to amuse you. First the Great Northern Snow Squirrel (that’s official – around this household anyway) enjoying his morning snack of cookies [JAC: There is no such species as the Great Northern Snow Squirrel]:

Then I came across the raccoon family [Procyon lotor] that used to live under the back deck. Here are five of them stealinf choke cherries:

We lived happily together and my son was foolish enough to tame them to hand feed:

L1000337-1

Making raccoons!

But when I was awoken one night by a terrible noise on my bedroom roof, relations cooled:

Eventually, carpenter ants ate some important structures at the back of the house, and the deck had to go as part of the rebuilding. The descendants of these raccoons now live under the barn next door.

Here are some fun facts on raccoons from Wikipedia. First, their dexterity:

The most important sense for the raccoon is its sense of touch. The “hyper sensitive” front paws are protected by a thin horny layer which becomes pliable when wet. The five digits of the paws have no webbing between them, which is unusual for a carnivoran. Almost two-thirds of the area responsible for sensory perception in the raccoon’s cerebral cortex is specialized for the interpretation of tactile impulses, more than in any other studied animal. They are able to identify objects before touching them with vibrissae located above their sharp, nonretractable claws. The raccoon’s paws lack an opposable thumb; thus, it does not have the agility of the hands of primates. There is no observed negative effect on tactile perception when a raccoon stands in water below 10 °C (50 °F) for hours.

Note that the “lotor” in the species name Procyon lotor is Latin for “washer,” referring to their habit of dunking their food in water before eating it. It’s not clear why they do this.

Here are the vibrissae (“hand whiskers”):

And their renowned intelligence (I’m not vouching for these studies as I’ve not read them):

Zoologist Clinton Hart Merriam described raccoons as “clever beasts”, and that “in certain directions their cunning surpasses that of the fox.” The animal’s intelligence gave rise to the epithet “sly coon”. Only a few studies have been undertaken to determine the mental abilities of raccoons, most of them based on the animal’s sense of touch. In a study by the ethologist H. B. Davis in 1908, raccoons were able to open 11 of 13 complex locks in fewer than 10 tries and had no problems repeating the action when the locks were rearranged or turned upside down. Davis concluded they understood the abstract principles of the locking mechanisms and their learning speed was equivalent to that of rhesus macaques. Studies in 1963, 1973, 1975 and 1992 concentrated on raccoon memory showed they can remember the solutions to tasks for up to three years. In a study by B. Pohl in 1992, raccoons were able to instantly differentiate between identical and different symbols three years after the short initial learning phase.Stanislas Dehaene reports in his book The Number Sense raccoons can distinguish boxes containing two or four grapes from those containing three.

Finally, baby albino raccoons (and the wild type) from Pinterest:

Caturday felids: Surprise cat, feral moggies, cat toes, cat cosmonaut, and Harry in disguise

June 13, 2015 • 7:45 am

We have five cat features today! First, a guy gives his girlfriend the kitten she’s always wanted. This is adorable:

*******

Like many of us, reader Ken Phelps (whom I met in Vancouver) likes to photograph the local cats when he’s traveling. Here are a few selected shots:

This guy (?) was sitting on a porch in Reykjavik. Just at the start of May, sunny but with a very cold wind right around freezing. Any cat with outdoor privileges in this climate needs to be tough, and this cat certainly looked the part. Accepted a reasonable amount of head and neck scratching then just gave me a good dismissive swat. He got up and walked approximately 12 inches, sat back down and gave me a look that just said “We’re done, right? ‘Cause I’m staying right here.”

There were a lot of cats that looked related, very tough and very attractive. Presumably a bit of a restricted gene pool.

There were a a lot of pretty sad looking strays there, but this one seems to be doing well. He was wary and not approachable – at least not without a treat – but not too skittish either. His general look of well-being suggests some people skills.

I had heard that “there’s a reddit devoted to everything,” but I didn’t believe that until someone pointed to reddit: Jelly Bean toes, devoted entirely to pictures of cats’ toes. Three examples out of gazillions:

Saturday: Hili dialogue

June 13, 2015 • 5:21 am

It’s Convocation at the University of Chicago today (otherwise known as Graduation Day), and the campus will be a madhouse. All the chairs are set out on the quad—outside, and that’s bad given the weather report:

Screen shot 2015-06-13 at 5.11.06 AM

It is gray and foggy, and not a nice day to sit outside and listen to speeches. (There is no inside alternative; participants are given cheap plastic raincoats if it gets wet.). I don’t participate—I do so only when I have a student graduating—but maybe I can score some free noms.) Meanwhile in Dobrzyn, Cyrus, normally not overly bright (I am a d*g ableist), shows some interest in biology. Perhaps a little cat will teach him.

Hili: What are you looking at so intently?
Cyrus: I’m observing what evolution did to a snail.

Hili: Czemu się tak przyglądasz?
Cyrus: Patrzę co ewolucja zrobiła ślimakowi.

Rock climbing bears

June 12, 2015 • 3:30 pm

Alex Honnold has nothing on these bears. Although I knew of the fearlessness and dexterity of wild sheep and goats on vertical rock slopes (the ones who weren’t so skillful didn’t leave descendants!), I wasn’t aware that bears had joined the rock-climbing club. The information below comes from Stephanie Latimer, who made the video in Big Bend National Park. Mexican black bears are simply a population of regular black bears (Ursus americanus)

Endangered Mexican Black Bears (momma and cub) climb Santa Elena Canyon wall, March 21, 2014. I spotted them while I was kayaking and want to share with you my nature loving, rock climbing, suspenseful satisfaction.

The National Park Service notes that the species is very rare in the park:

There are approximately 8–12 adult bears living in Big Bend, and biologists believe the environment has supported 25 to 30 bears. Though, as with most creatures in a desert environment, fluctuations in their numbers occur from time to time.

There might have been fewer had mom or the cub not been so adept on the rocks!

More “anonymous” comments

June 12, 2015 • 3:06 pm

I keep getting comments from people who either too clueless to make up a pseudonym or, quite often, simply don’t want to insert a name because their comments are rude or offensive.  As I mentioned before, given the plethora of comments from “Anonymous” people, who can’t be distinguished one from another, I won’t post any comment not associated with some kind of name. All “anonymi” will be deep-sixed.

And, as always, I prefer (but don’t require) that readers use their real names, which I firmly believe helps promote civility and rationality on the Internet. Finally, if you ever want a reply or if you think I may want to contact you, it would behoove you to also put down your real email address, which of course I will never disclose.

Comedians avoid the “offense circuit”

June 12, 2015 • 1:00 pm

From the St. Louis Post-Dispatch, we learn that at least two famous comedians have decided not to perform on college campuses, and for the same reason: colleges are too “politically correct,” that is, they embody the humorless offense culture:

Jerry Seinfeld himself has taken a stand — against political correctness on campus. The 61-year-old comedian told an ESPN interlocutor that he avoids performing at universities because of trigger warnings, speech codes and other First Amendment umbrage.

“I don’t play colleges,” Seinfeld said on “The Herd with Colin Cowherd.” “… I hear a lot of people tell me, ‘Don’t go near colleges. They’re so PC.'”

. . . Cowherd: “Does it hurt comedy?

Seinfeld: “Yes it does.”

As Seinfeld reported, he is not the only comedian to comment on colleges’ perceived uptight-ness.

“I stopped playing colleges, and the reason is because they’re way too conservative,” Seinfeld compatriot Chris Rock told Vulture last year.

Conservative how?

“Not in their political views — not like they’re voting Republican — but in their social views and their willingness not to offend anybody,” Rock said. “Kids raised on a culture of ‘We’re not going to keep score in the game because we don’t want anybody to lose.’ Or just ignoring race to a fault.”

So much worse for the colleges.  I especially like Chris Rock. Here’s one of his bits that, though not nearly as salacious as many of his performances, would still not go down well on campuses:

Apropos, here’s today’s Pearls Before Swine strip by Stephan Pastis, a comic I don’t really know:

Sir Tim Hunt inserts metatarsals into buccal orifice

June 12, 2015 • 11:45 am

In 2001, Tim Hunt (now Sir Tim Hunt) won the Nobel Prize for Medicine or Physiology along with Paul Nurse (now Sir Paul Nurse) and Leland Hartwell for the discovery of how certain proteins (kinases) regulate cell division. But, like James D. Watson, Hunt has now come into disrepute by making statements that demean minorities: in Watson’s case it was blacks; in Hunt’s it was women scientists.

As The New York Times reports, Hunt’s comments, uttered at the World Conference of Science Journalism in Seoul, involved denigrating women’s supposed overemotionality, and the effects they have on making men (including Hunt) fall in love with them, which, says Hunt, causes big problems in the lab. He called, in fact, for “sex-segregated labs” to prevent this problem, as if labs were some kind of Catholic school.

Hunt’s remarks first received public attention via the following tw**t by Connie St. Louis, head of the science journalism program at City University London:

Screen Shot 2015-06-12 at 8.26.13 AMOf course the expected tsunami of criticism ensued, for these remarks are unconscionable, and were instantly added to Hunt’s biography on Wikipedia, where they’ll remain forever. Hunt subsequently issued a clarification, but didn’t really apologize for what he said; he simply explained his statement and said he was sorry if he had caused any offense. That, of course, shows no contrition at all for denigrating women scientists. But he also resigned his position at University College London (Hunt is 72).

The issues remain: women are perceived as “Eves” in the lab, who distract men from doing science (Hunt’s desired segregation would of course prevent both sexes from benefitting from each others’ ideas and work); that there can be real problems of harassment of women and an imbalance in the power structure of science (more rarely, that can obtain for men in labs headed by women, and, at any rate, universities have rules outlining what constitutes harassment); and that women can be seen as “weaker” creatures whose sentiments must be coddled. Each of these just adds another drop in the heavy bucket on the heads of women scientists, making them think, “Seriously? Do we still have to put up with this crap?”

Some writers have called for Hunt’s FRS (Fellow of the Royal Society) membership to be revoked (the Royal Society has distanced itself from Hunt’s remarks), and even for his knighthood to be nullified. I don’t agree, for there are all kinds of jerks who are “Sirs” and FRSs, and ultimately it’s scientific accomplishment, not impeccable character, that brings these honors.

Still,  I’m very proud of the way women scientists have acted to mock and dispel these notions. First there is this tw**t from Kate Devlin, researcher at Goldsmith’s University London:

Matthew and Nick Lane at the Royal Institution

June 12, 2015 • 10:30 am

Reader Dom sent two photos from Matthew’s book talk (and one by Nick Lane). See this very positive review of Matthew’s book, Life’s Greatest Secret, in the Guardian. Nick Lane’s new book, The Vital Question, has also garnered rave reviews.  I haven’t yet read Nick’s book (but I will), but I can say that Matthew’s is excellent.

I went to Nick Lane & Matthew’s talks at the Royal Institute last night. Both very good, & don’t tell him I said this but Matthew is an excellent lecturer.

I asked Dom if I could impart that information to Matthew anyway, and he said, “yes.”

Nick Lane (l) and Matthew:
