Readers’ wildlife photographs

October 18, 2015 • 7:30 am

Readers are invited to send in their GOOD wildlife photos; some have answered my plea yesterday and I’ve put their pictures in the queue.

First at bat is Jacques Hausser from Switzerland, who’s sent us some rare marine photos:

During the annual field course of marine (or rather coastal) ecology and faunistic of the University of Lausanne, at Roscoff in Brittany, the students easily miss this tiny cephalopod, Sepiola atlantica (extended length about 4.5 cm [JAC: about 1.8 inches: tiny!]). First it is usually burrowed in the sand, and more, with its remarkable black, yellow and brown chromophores, it can change its coloration to adapt to the local background. Coloration changes also very quickly when the animal is perturbed. These two pictures were taken exactly 1 minute and 13 seconds apart  (you can see the same bubble growing on the rear of the mantle). The animal was returned unharmed to its biotope after observation.

I love pictures of raptors: they’re dignified and gorgeous, although what they do to other animals isn’t pretty. And here’s a great photo by a new contributor, Adam Mitchell, showing one in action—or rather right after action:

This photo was taken in Bend, Oregon in December last year. I believe it is a female Merlin (Falco columbarius) holding a freshly caught Cedar Waxwing (Bombycilla cedrorum). The bird landed on the fence outside my wife’s home office window; the photo was taken at a distance of about four metres through glass. I presume it was resting after the hunt as it stayed for approximately ten minutes holding the Waxwing then flew away.

These photos, sent by reader Randy Schenck from the American Midwest, aren’t really of wildlife, but for those of us who don’t know where our food comes from. or foreign readers unacquainted with American large-scale farming, I thought they’d be interesting. It’s corn harvest time here:

Just something different from here in farm country.  Today the farmer handling our place is “picking” the corn as they sometimes call it, using a combine seen in the first two pictures.  They are currently running two of these machines as he does have many acres to get to.  The third photo is support equipment as the object is always to empty the combine so it continues to work without delay.  This is called a grain wagon along with an appropriately sized tractor to handle the load.  This wagon handles 1150 bushels of corn when full: 64,400 lbs. of net weight [JAC: about 29,400 kilos].

This can be a family enterprise as it is in this case.  The farmer works with his dad, another son and one hired person.  It is not unusual to see his wife driving a tractor or one of the combines.

Sunday: Hili dialogue (and Leon lagniappe)

October 18, 2015 • 5:02 am

It’s Sunday, and tomorrow at noon I’ll finally be making my way home to Chicago, where the weary traveler will find rest. It’s been a long trip but a good one, and I will return as an emeritus professor, superannuated but optimistic.  Meanwhile, life goes in in Dobrzyn, and the Furry Princess of Poland is, as always, peckish:

Hili: Do you really enjoy your breakfast in the company of a hungry cat?
A: But you just ate.
Hili: Only the appetizer.

P1030491 (1)

In Polish:

Hili: Czy naprawdę smakuje ci to śniadanie w towarzystwie głodnego kota?
Ja: Przecież jadłaś?
Hili: Tylko przystawkę.
*******

 

And the lagniappe: a Leon monologue. In Włocławek, 30 minutes from Dobrzyn, The Dark Tabby is very upset at his fruitless outing. Look at that face!

Leon: Neither mushrooms nor mice…

University of Texas Professor resigns over new gun law

October 17, 2015 • 12:30 pm

As I reported the other day, there’s a new law in Texas allowing anybody with the proper permit to carry concealed handguns on college campuses in the state, including both public and private schools. Unfortunately, it hasn’t seemed to elicit much protest from faculty (although there’s a movement afoot for students to open-carry dildos as a protest when the law takes effect next summer). I would have thought that many of my academic colleagues in Texas would have objected strenuously in the form of a public letter—not that it would have done anything, for the gun lobby and their supporters are too strong.

But one professor did take a stand: a bold one, for he resigned his job. According to KXAN in Austin, Daniel Hamermesh, a well-known professor of economics at UT Austin, has quit his job at the University because of the dangers of concealed carry on campus.

Hamermesh (photo at bottom) is an emeritus professor, but still teaches every year (something we University of Chicago emeriti are, sadly, prohibited from doing), so his resignation is meaningful for the university and students. As KXAN notes, “Hamermesh began at UT in 1993 and retired in 2014, teaching more than 8,000 students, mostly in large classes of Introductory Microeconomics. He says his current class has 475 students.”

The letter is below, but if you’re myopic the site gives a summary:

In a letter to UT President Greg Fenves, Daniel Hamermesh writes, “The risk that a disgruntled student might bring a gun into the classroom and start shooting at me has been substantially enhanced by the concealed carry law.”

Hamermesh retired in August 2014, but continued on as the Sue Killam Professor Emeritus, teaching every Fall through 2017. The professor says the law, which will allow students to carry concealed weapons on designated areas of campus, will make it much more difficult for UT to attract employees.

“The issue is not people like me, I’m small potatoes, the real issue is that for Texas, for people who are thinking about coming here, they have lots of alternatives. The ones we want to hire here do have alternatives,” said Hamermesh.

As for his immediate future at the university, Hamermesh says he will spend part of next Fall at the University of Sydney, “where, among other things, the risk seems lower.” He also expressed shock that he is the only current member of faculty who is disturbed by the new legislation.

He feels the gun laws at his new post in Sydney will ease his mind.

“Of course I feel much safer there, because there’s very little gun violence there that there is here,” said Hamermesh.

World’s largest collection of natural sounds has some doozies

October 17, 2015 • 12:30 pm

Reader Jim E. called my attention to a great resource for naturalists and biology-lovers: Cornell University’s famous Department of Ornithology has put up the world’s largest library of digitally-encoded natural sounds: the M. L. Macaulay Library. There are hundreds of audios and videos, and you can browse by taxon. There are 2853 audio clips  (and 725 video clips) of owls alone! This is really a treasure trove.

I’ll introduce you to just a few lovely sounds as noted on the Cornell Tumbler and Macaulay site itself, with these notes from the former site:

It took archivists a dozen years to complete the monumental task. The collection contains nearly 150,000 digital audio recordings equaling more than 10 terabytes of data with a total run time of 7,513 hours. About 9,000 species are represented. There’s an emphasis on birds, but the collection also includes sounds of whales, elephants, frogs, primates and more.

“Our audio collection is the largest and the oldest in the world,” explained Macaulay Library director Mike Webster. “Now, it’s also the most accessible. We’re working to improve search functions and create tools people can use to collect recordings and upload them directly to the archive. Our goal is to make the Macaulay Library as useful as possible for the broadest audience possible.”

The recordings are used by researchers studying many questions, as well as by birders trying to fine-tune their sound ID skills. The recordings are also used in museum exhibits, movies and commercial products such as smartphone apps.

Your essential evolution library

October 17, 2015 • 11:30 am

by Greg Mayer

I frequently teach evolutionary biology in the spring semester, but for various reasons I will not be teaching it this coming spring. A few days ago, a student who wanted to take the course, but now couldn’t, asked what he could read in lieu of taking it. We discussed some suggestions, and then I sent him a copy of a chapter on “The evidence for evolution” that I’d written for The Princeton Guide to Evolution, edited by my friend and colleague Jon Losos. The point was not for him to read the chapter (although there’s nothing wrong with doing that!), but rather to send him the list of “Further Reading” that closed the chapter. The Guide is intended for students, and for scientists reading outside their specialties, so the recommended readings are not at a highly technical level, but can be edifying for any curious and interested reader. We were limited to ten, and here’s what I chose.

Young, D. 2007. The Discovery of Evolution. 2nd ed. Cambridge: Cambridge University Press. Though last alphabetically, I list this one first, because it is a truly excellent book that is not well enough known (though I’m trying!) Ostensibly a history of evolutionary biology, it serves as a text for evolutionary biology itself, because it introduces and explicates not just the ideas and historical figures, but the evidence on which the major discoveries of evolutionary biology are based. It is intended for a general audience, and richly illustrated.

Carroll, R. 2009. The Rise of Amphibians: 365 Million Years of Evolution. Baltimore: John Hopkins University Press. This book, by the dean of North American paleontology, is a bit more technical, and includes accounts of the origins of vertebrates and reptiles, as well as of the origin of amphibians.

Coyne, J. A. 2009. Why Evolution Is True. New York: Viking Penguin. ’nuff said.

Dawkins, R. 2009. The Greatest Show on Earth. New York: Free Press. Another account of the evidence for evolution for a general audience, by another person we all know.

Futuyma, D. J. 2013. Evolution. 3rd ed. Sunderland, MA: Sinauer. This is the leading undergraduate textbook of evolutionary biology, and is a good read for biology majors. It would require a bit more effort from a general reader, but it’s chock full of good stuff and worth the effort. Doug’s 1997 Evolutionary Biology (Sinauer) is more of a graduate level text, and, though a bit dated in spots, is more comprehensive and still quite worthwhile.

Grant, P. R., and Grant, B. R. 2008. How and Why Species Multiply: The Radiation of Darwin’s Finches. Princeton, NJ: Princeton University Press. The Grants have published a number of more technical books on their groundbreaking work in the Galapagos on Darwin’s finches, but this volume provides a more accessible overview of the detailed evolutionary studies they and their associates have conducted over four decades, including several episodes of closely observed evolutionary changes. They have recently published a more technical but still readable account, including several more years of field work, in 40 Years of Evolution (2014, Princeton University Press).

Mayr, E. 2001. What Evolution Is. New York: Basic Books. A summary of the evidence for evolution and its causes by the man Jerry has rightly called the “Darwin of the 20th century.”

Prothero, D. R. 2007. Evolution: What the Fossils Say and Why It Matters. New York: Columbia University Press. Intended for a general audience, this richly illustrated account of the fossil record emphasizes transitions between major groups, and is a great resource for understanding the broad outlines of evolutionary history and how we know how it happened.

Shubin, N. 2008. Your Inner Fish. New York: Pantheon Books. Another book by someone we all know, this is a popular account of the discovery of the fish-amphibian transitional form Tiktaalik, and of the traces of common ancestry in the anatomy and genes of vertebrates and other animals.

My tenth book was Darwin’s Origin of Species, but since almost every chapter could have cited it, and chapters before mine already had done so, it was left out. But I can add it back in here for WEIT readers.

Darwin, C. 1859. On the Origin of Species. London: John Murray. The modern reprinting which I read and usually cite from is the Harvard University Press reprint of 1964, with an introduction by Ernst Mayr. Although I have heard that some find Darwin’s “Victorian” style offputting (what do they want?– he was a Victorian), I find it quite readable, and still remarkably cogent and astute.

I can also add in here for WEIT readers the Princeton Guide, for which I prepared the original list. It has dozens of chapters by a top selection of evolutionary biologists (present company excluded!).

Losos, J.B., ed. 2014. The Princeton Guide to Evolution. Princeton, N.J.: Princeton University Press.

I would also add in a second evolution textbook, coauthored by the accomplished science writer Carl Zimmer, and by the scion of a distinguished biological family, Doug Emlen.

Zimmer, C., and D.J. Emlen. 2016. Evolution: Making Sense of Life. 2nd ed. Greenwood Village, Colorado: Roberts. Well written and well illustrated; at a slightly lower level than Futuyma (Z&E is sort of for sophomores, Futuyma for seniors; juniors could go either way). A great book for someone teaching an evolution course– very clear and well structured, with a variety of useful teaching aids.

Several years ago, Jerry prepared a list of the five books about evolution for general readers that he would pick. I did not consult Jerry’s list when I prepared mine for the Princeton Guide, so the comparison is of interest. The only one on both lists is Prothero. Jerry also chose the Origin (which would have been on my list if it had not already been recommended in the Guide); Dawkins’ Blind Watchmaker, which I too highly recommend; Janet Browne’s two volume biography of Darwin, which I again highly prize and recommend as well (although if you’ve only one history book to read, read Young’s Discovery of Evolution); and two books by Steven Jay Gould: an essay collection, and The Mismeasure of Man (they let Jerry pick 6 books). In comparing our lists, do recall the differences in the audiences for our lists– Jerry’s intended audience being nonscientist readers, mine being a bit of a hybrid, but leaning toward science students.

In teaching our undergraduate evolution classes, Jerry and I have both, at least at times, used Futuyma’s textbook and the Origin as our required readings. Although he and I have consulted occasionally on our teaching of evolution, I believe we arrived at our choices of books independently.

Readers’ wildlife photos

October 17, 2015 • 9:00 am

We have contributions from a new reader, Keith, whose notes are indented. Be sure to send me your GOOD wildlife photos, as the tank truly is running on low.

Here are photos of two of my favorite flowers: a Jackson Perkinks Rose called “Brass Band” in my front garden, and a day lily with bumblebee.

Attached you will find photos of praying mantis hatching in my back yard. I thought at first it was saw dust from my window but later went out and found this and took many pictures from beginning hatching trough the summer including two eying each other up for lunch in my planter. I am amateur photographer and I just tried to focus and shoot and I could not tell what I had taken until I downloaded them.

Finally, Stephen Barnard sent photos of elk (Cervus canadensis) doing what elk do: trying to increase the number of gene copies

There was a bit of a disagreement about whose cows these are. The bull with the biggest antlers wins.

Caturday felids trifecta: Dogs displaced from their beds, moar cat eye makeup (with contest), and the world’s happiest cats

October 17, 2015 • 8:00 am

We again have three felid-related items for Caturday. The first, from Buzzfeed (of course), shows that d*gs instinctively recognize that cats are their superiors. It’s a series of pictures showing “17 dogs who just want their beds back.” I’ll put up just four of the photos. Hili, of course, might well have been included, as she is wont to displace Cyrus from his bed. A small selection:

This is from reddit, labeled, “She got to enjoy her new bed by herself on Christmas day. The next day, the cats made sure she didn’t get her hopes up.”

This cat is truly The Boss (again from reddit):

Even kittens have the Power! (From reddit).

More cat eye make-up from Scarlet Moon on Deviant Art. Any reader who does the best job of duplicating something like this will get a free, autographed copy of  WEIT, with, of course, a cat drawn in it. (only one winner among entries, deadline Oct. 31: Halloweeen!):facebook_1445071287957

Finally, again from BuzzFeed, “27 of the happiest cats in the world“. I’ll show a half dozen. (BuzzFeed of course thrives on these “listicles,” and I’m a sucker for them when they’re about cats).

This kitten hit the mother lode! An imgur photo labeled, “For me? You shouldn’t have!”

A gif from giphy.com, labeled “I’m so happy you’re home!” Wouldn’t it be nice to have a cat who did this?

Talk about kicking a d*g when it’s down! This cat takes advantage of the Cone of Shame (from imgur):

Pictures like this, which show a cat using the Rong Toy, are almost a cliche of the internet. Still, this is a good one, as the cat is really happy! (From imgur, labeled “My cat being a jerk, and then laughing at me.”).

Saturday: Hili dialogue

October 17, 2015 • 6:30 am

When I was in Dobrzyn this time, I noticed a small and unprepossessing shack labeled “Al Capone’s Pizza.” It’s the only takeout joint in Dobrzyn. (Apart from that the town has only one restaurant, and believe me, you wouldn’t want to go in, as it’s full of sullen, thuglike men drinking vodka. I did not see any food on the tables). Malgorzata and Andrzej told me they sometimes order a pizza from Al Capone’s, and I asked if I could order one for all of us. They told me “No way,” as the pizzas weren’t that good, and besides, I hail from the Pizza Capital of the World. After I left, they broke down and ordered one, sending me the photo. It was the ugliest pizza I’d ever seen, and I asked if it was good. The response was an emphatic “no!”, with Malgorzata adding,: “The white stuff on it pretended to be cheese but I have no idea what it was in reality. Definitely not anything edible.” The stuff in the white plastic cup at lower left is garlic sauce.

A: I haven’t eaten such an awful pizza in all my 76 years.
Hili: But you are 75.
A: Counting since conception.

Ja: Od 76 lat nie jadłem tak wstrętnej pizzy.
