Snow leopard baby boom

August 28, 2013 • 4:40 am

Here’s a guest post by Greg, but I have to weigh in at the start and say that snow leopards, are, I think, the most beautiful cats in the world next to tigers. –Professor Ceiling Cat

by Greg Mayer

Snow leopards (Panthera uncia) are a species of large cat found in the mountains of Central Asia, where they are predators of sheep, goats, and other mammals and birds. They are listed as Endangered by the IUCN. Both the Bronx and Brookfield Zoos have recently had births of snow leopards, and made announcements almost at the same time.

The Bronx Zoo’s cub is older, born April 9, and first shown to the public this week.  The New York Times has several great pictures, and it was hard to pick one– you should go look at them all! Ah, what the heck: I can’t pick just one. Here’s another:

Brookfield’s cub was born June 13, and its birth was just announced; it is not yet on exhibit. There are several great photos at Brookfield’s website. To give the Bronx and Brookfield equal treatment, here are two pix of the Brookfield cub.

Here’s the Bronx Zoo’s cub running around with its mother:

Both cubs were born through mating programs designed by the Association of Zoos and Aquariums Species Survival Plan Program. (Here’s an old description of the snow leopard program, published originally in the sadly now-defunct Endangered Species Update). There are several groups that promote snow leopard conservation, including the IUCN, the Snow Leopard Trust, the Snow Leopard Network, the Snow Leopard Conservancy, and Panthera (see their brochure here).

Among cat species, snow leopards are the best adapted to high altitudes. They are long-haired, pale in color, and adept at moving on rocky slopes (and are sometimes hard to see!). [JAC: as you can see in the video above, they also have huge footpads that act like snowshoes, helping them move about on the snow.)

They are sometimes placed in a separate genus, Uncia, but they seem to fall phylogenetically well within the other big cats (Panthera), and their distinctive features reflect their high-altitude adaptations rather than a deeper separation in time from other felids.

In addition to being adapted to high altitudes, they are also unbearably adorable when young.

Two comments in the queue

August 27, 2013 • 2:38 pm

One of these people won’t be posting here again (guess which one), but I thought these comments were humorous, even though both were meant seriously:

1.  From Mel Shuller:

Anyone who uses the non-word, irregardless, instantly loses his/her credibility with intelligent, thinking people!!!

My response:  Anyone who completely disregards someone’s ideas over an issue as trivial as this is a pompous ass.

2.  From ian:

why do you put a star in dog

My response: Every regular reader here knows the answer.

Christian liars tout Ray Comfort’s new creationist film; an atheist dismantles it

August 27, 2013 • 11:31 am

About two weeks ago I presented and criticized Ray Comfort’s latest piece of tripe film, “Evolution vs. God,” in which he accosts various students and biologists and tries to flummox them by making them produce the only evidence for evolution he’ll accept. And that happens to be showing one “kind” of animal transforming into another kind in real time. That is, you need to show Comfort a reptile evolving into a bird before your eyes.

The movie, of course, is being touted by creationists as a deliberate tour de force.  I don’t want to summarize all that palaver, but reader Chris called my attention to one blurb for the movie that he characterized as “low-hanging fruit.”  It’s on the WND Faith site, and is called “Watch evolutionists stumble over theory’s ‘proof’“.

Yeah, that’s some “proof” Comfort’s asking for.  It’s like asking him to “prove” the tenets of his faith by showing us Jesus coming back to life after crucifixion in real time. Where’s the damn movie of that?

I won’t go on except to highlight the low-hanging fruit.  The WND blurb begins this way:

Imagine having a worldview that permits rape, murder, homosexuality, pornography, abortion, blasphemy and adultery.

Now imagine this worldview being taught to generation after generation and how it would eventually destroy the foundations of any nation.

And imagine if it was taught as legitimate science.

Such is Darwinian evolution, according to the maker of a new DVD, who contends the theory helped form the ideological foundation for Hitler’s Holocaust and the effort to rid America of God and any moral accountability.

Really? Evolutionary biologists have no problem with rape, murder, or adultery?  As for homosexuality, abortion, or even non-abusive pornography, I don’t have problems with them.  But yes, I am in favor of blasphemy, but that’s because I’m an atheist, not an evolutionist.  Comfort and his minions, in insisting that evolution sanctions gross immorality, are lying, and know that they’re lying. In fact, we’re more moral than Comfort, because when we have evidence, we don’t lie to avoid confronting it.

The site also has a short video clip with more lies, taking a bit of an anti-Comfort YouTube video by Jaclyn Glenn and turning it into their propaganda. They simply excerpt her real video (below) and then slap their own “there’s-no-evidence-for-evolution” mantra over it.

These people need to read my book, but of course they won’t accept that as evidence, either. I need to show them a dog evolving into a cat.

Anyway, courtesy of Hemant Mehta, here’s Glenn’s full-length video rebuttal of Comfort’s film. It’s good.

More bad usage

This sign, which I photographed on the Metra “electric train” downtown, has the same problem as the television ad I posted about recently (and can’t find):

Usage

Apparently if you’re with a senior, you can have a special seat, too. Or perhaps you get your special seat only if you have both a disability and a senior with you.

I have a hobby

August 27, 2013 • 6:00 am

. . . but it’s a bird, not an avocation.  In fact, until yesterday morning I didn’t know what a hobby was until I got the following picture (I’ve cropped it a bit) from reader Christian with this note:

It’s a bank holiday here in London, and I spent some of the afternoon on the bank of the Thames watching a Hobby, a pretty rare sight in London. Not the best of shots, but attached are a couple of photos, including one of it eating a dragonfly which I saw it catch in flight. Alas I’m not a good enough photographer to have caught the hunt itself, but an amazing sight.

Here’s one of Christian’s shots; you can see the dragonfly in the hobby’s talons.

Hobby

But of course I didn’t know what a “hobby” is, so I asked Christian and got this answer:

A hobby is a small falcon. It migrates to Africa following swifts/swallows, and breeds in the uk, although there aren’t many of them around (I think they are however slightly more common that the peregrine). They are amazing in the air and can catch dragonflies, swifts and swallows on the wing—first time I’ve seen it today, an incredible sight.

Wikipedia tells me (shoot me; it seems pretty reliable on biology) that there are actually four falcons in a monophyletic group, each of which is called a “hobby.” This one is apparently the Eurasian hobby, Falco subbuteo, whose skills are described below:

 It flies powerfully and fast. It will take large insects, such as dragonflies, which it transfers from talons to beak and eats while soaring slowly in circles. It also captures small bats and small birds like swallows, swifts, pipits etc. in flight. Its speed and aerobatic skills enable it to take swallows and even swifts on the wing, and Barn Swallows or House Martins have a characteristic “hobby” alarm call. It is known to harass swallows while they are roosting and dispersing from roosts. When not breeding, it is crepuscular, hawking principally in the mornings and evenings. While on migration, they may move in small groups.

Have other readers seen this bird in London?

She’s Leaving Home

August 27, 2013 • 4:44 am

“She’s Leaving Home,” on the Beatles’ album “Sgt. Pepper’s Lonely Hearts Club Band”, comes in at number 82 on Rolling Stones’ list of the 100 Greatest Beatles Songs. The link notes that it’s based on a true story:

“She’s Leaving Home” was inspired by a newspaper story about a well-to-do 17-year-old girl named Melanie Coe who disappeared from her parents’ home in London. While McCartney took the perspective of the teen runaway, Lennon sang counterpoint (the “Greek chorus,” as McCartney called it) in the voice of the heartbroken parents.

The real-life Melanie Coe ended up going back home to her mom and dad after three weeks; she was pregnant and had an abortion. But the girl in the song represented all the teenagers who were running away from their conventional lives in the Sixties. In April 1967, McCartney visited Brian Wilson in L.A. to preview Sgt. Pepper, playing “She’s Leaving Home” on the piano for him and his wife. “We both just cried,” Wilson said. “It was beautiful.

This came out in 1967, and again, there was nobody writing anything like this at the time. Indeed, if you listened to it and didn’t know who did it, you’d be hard pressed to say that this is rock and roll. It’s just a beautiful ballad.

The antagonistic parent/offspring counterpoint reminds me strongly of Cat Stevens’s “Father and Son,” also a great song.

Wikipedia notes that it’s one of the few Beatles songs in which none of them play an instrument; it was accompanied by a string orchestra arranged not by George Martin, but Mike Leander, who arranged for many rock artists. They also give a quote from McCartney in his biography, Many Years from Now (I haven’t read it; has anyone?):

John and I wrote ‘She’s Leaving Home’ together. It was my inspiration. We’d seen a story in the newspaper about a young girl who’d left home and not been found, there were a lot of those at the time, and that was enough to give us a story line. So I started to get the lyrics: she slips out and leaves a note and then the parents wake up … It was rather poignant. I like it as a song, and when I showed it to John, he added the long sustained notes, and one of the nice things about the structure of the song is that it stays on those chords endlessly. Before that period in our song-writing we would have changed chords but it stays on the C chord. It really holds you. It’s a really nice little trick and I think it worked very well. While I was showing that to John, he was doing the Greek chorus, the parents’ view: ‘We gave her most of our lives, we gave her everything money could buy.’ I think that may have been in the runaway story, it might have been a quote from the parents. Then there’s the famous little line about a man from the motor trade; people have since said that was Terry Doran, who was a friend who worked in a car showroom, but it was just fiction, like the sea captain in “Yellow Submarine”, they weren’t real people.

The synergy between Lennon and McCartney amazes me. The moment the group disbanded, neither of them wrote much on their own that even came close to what they wrote together. Yes, there were a few exceptions, like “Imagine”, and I still think McCartney’s “Jet” and “Maybe I’m Amazed” would have been worthy of the Beatles, but the magic was gone. Harrison was the only one who produced a string of excellent songs after the Beatles disbanded.

Wikipedia adds two more tidbits:

When discussing Sgt. Pepper’s Lonely Hearts Club Band, composer Ned Rorem described “She’s Leaving Home” as “equal to any song that Schubert ever wrote.”

and

In a bizarre coincidence, Coe had actually met McCartney three years earlier, in 1963 when he chose her as the prize winner in a dancing contest on ITV’s Ready Steady Go!. An update on Coe appeared in the Daily Mail in May 2008, and she was interviewed about the song on the BBC programme The One Show on 24 November 2010.

Here’s the video of Macca meeting Melanie Coe on television. Little did he know that she’d later feature in one of his best songs!

Bamboo shark walks the walk

August 27, 2013 • 1:49 am

by Matthew Cobb

This video of a bamboo shark (Hemiscyllium halmahera) strolling across some coral was posted on Twitter by Kyle Hill (@sci_phile):

This oviparous species, which is about 70 cm long, has just been described by Dr Gerald Allen of the Western Australian Museum. For the shark-heads out there, the abstract of the paper says:

Hemiscyllium halmahera new species is described from two specimens, 656-681 mm TL, collected at Ternate, Halmahera, Indonesia. The new species is clearly differentiated on the basis of colour pattern. Its features include a general brown colouration with numerous clusters of mainly 2-3 dark polygonal spots, widely scattered white spots in the matrix between dark clusters, relatively few (< 10), large dark spots on the interorbital/snout region, a pair of large dark marks on the ventral surface of the head, and a fragmented post-cephalic mark consisting of a large U-shaped dark spot with a more or less continuous white margin on the lower half, followed by a vertical row of three, smaller clusters of 2-3 polygonal dark marks. The new species is most similar in general appearance to H. galei from Cenderawasih Bay, West Papua, which differs in having 7-8 large, horizontally elongate dark spots on the lower side between the abdomen and caudal-fin base, a cluster of solid dark post-cephalic spots, and usually about 25 dark spots on the upper surface of the head.

But the really interesting thing to me is the gait the fish is using – this is apparently typical of Hemiscyllium sharks, which prowl across coral looking for food. It is using the classic alternate movement of a tetrapod.

We’ve previously talked about the evolution of the tetrapod gait in lungfish. Now you are more closely related to Tiktaalik, the famous fish/tetrapod intermediate form, than Tiktaalik was to a shark (because you and I and Tiktaalik all have bones; sharks do not have bones, only cartilage).

So this suggests that the neuronal control of the way that you run (your right arm moves with your left leg, and your left arm moves with your right leg – try it) goes waaaayyyy back even beyond our fishy ancestors, to the time before the evolution of bone.

Another alternative is that this is convergent evolution – if you are going to ‘walk’, the alternate gait is the best way of doing it. Today’s question: How could we test between these two hypotheses?

I may be exaggerating the importance of this gait in sharks – are there any locomotion experts out there who can comment?

The film was made near Ternate, on the Malaku islands in Indonesia, by Mark Erdmann of wedaresort.
