After the intensity of the last post, here’s something relaxing, beautiful, and meditative….an underwater ballet: The Cirrate octopus undulates through the dark depths of the Taney Seamounts, west of San Francisco. This gem comes to us through Boingboing, and was shot by the Monterey Bay Aquarium Research Institute (MBARI). Click here for the article and video, and enjoy. 🙂

The Post – Ants, Baby-Boomers, and the Greater Good
January 7, 2011The BBC Online just published an article: Leaf Cutter Ants Retire When Their Teeth Wear Out. Now given the title of this post I can imagine you’re connecting ants to Baby-Boomers and protesting that we have better dental care so no forced retirement for us! 🙂 But not to worry.
Quite to the contrary, in reading the article, I was struck by a similarity between the two groups that has nothing to do with teeth, but a lot to do with continuing to have a valuable contribution, even as we age.
The BBC article summarizes research done by scientists at the University of Oregon and that was published in the journal, Behaviour Ecology and Sociobiology. I know, sounds like a real page-turner. But bear with me just a bit.
Apparently, using electron microscopes, they were able to verify that pupae of the leaf-cutter ant from Panama, Atta cephalotes, have mandibles as sharp as any razor blade we’ve developed and hence work great for chopping up leaves. Older ants, however, have much duller mandibles, about 340 x duller than pupae and it takes them twice as long to cut up leaves. Some of the older ants only have about 10% of the sharp cutting material left.
The leaves, by the way, are used in food production for the colony. The ants apparently use the sap for food, and they also use the leaf material to grow a fungus, also as food for the colony. (The fungus is a member of the Lepiotaceae family.)
Anyways, given that the most labor-intensive job in the colony is the chopping of leaves, the ants have developed a system where the youngest ants do the cutting, and older ants carry the leaves back to the nest. They have devised a means where an older ant with little cutting ability left, can actually make a contribution to the colony doing a job they are better suited for. This serves the greater good by allowing the younger ones to what they do best – keep on cutting.
I thought about our society where often Baby-Boomers want to continue in a career path well into their later years rather than just heading out to pasture. But often we need to reinvent ourselves a bit – pursue that career from a different angle, use our years of experience as a pro to make the whole effort more efficient. Do tasks we are best suited for.
I have a 30+ year medical and pharmaceutical research background. More recently I wanted to continue using that background but in a new way. I am now volunteering at a local science museum, using those 30 years of science, to reach out to the new generation coming up and fire them with a love of science. It is work I am better suited at now. I admire those my age who can still work double shifts or all-nighters at the local hospital lab. It is no small achievement. I have been given the chance to avoid that, so I find my usefulness in other ways.
It carries over into other areas of life too, not just careers. It snowed recently and my husband and I were preparing to go out and shovel the driveway. Our 22-year-old son stopped us and told us he had it covered. In a short period of time he completed a job that I am still able to do but which would have taken me much longer. His willingness to step up to something he was best suited for, allowed me to work inside on things I was better suited to do. I felt tremendous gratitude.
So when I read about the leaf-cutter ants, I think, re-invention, and remember my son and the snow. 🙂
The Post – Bird Deaths, Another Take
January 6, 2011Here is an article that quotes a Smithsonian bird expert as stating the large bird deaths around the country and world are not necessarily surprising or concerning. The author proceeds to offer different possibilities for what happened and why these events are probably not related or cause for worry. Whether you agree or disagree, it is an interesting read, and the author does raise the issue that humans have a penchant for pattern-finding, except many times the “patterns” aren’t ones, and the “connections” don’t exist. I share here for a different point of view.

The Post – Animal Deaths and Mental Shutdown
January 6, 2011I’ve been following somewhat off and on, the massive fish and bird die-offs being mentioned in the news. I kept up with it when it was the red-winged blackbirds in Arkansas, then the additional birds in Louisiana, and even kept up with dead fish in Sweden and dead crabs on the coast of England. I was trying to create a mental picture of it all to see if there was any “connection” or “pattern” or even how they all related to each other geographically.
But if you’re like me, you can take in just so much “data” and then the mental picture evaporates, the brain seizes up, gives out one last exasperated gasp folds in on itself in a quivering mass of jelly. Needless to say, one too many animal death groups appeared in the news and suddenly, it was all one chaotic blubbering mass of info that my brain could no longer process.
At the science museum I volunteer at, we are working on displays for a new lab area. This area is called ‘visualization.’ Essentially it is the use of technology to display visually, large amounts of data points that are beyond the ability of the brain to contain, much less put in any kind of meaningful order. It is used in science and a variety of other situations where you need to review a lot of data, try to find some meaning or understandings so as to draw possible conclusions or form theories. Without these tools it would be impossible to deal with the huge about of information. To read more on this subject see the entry at Wikipedia.
Anyway, I was lost in the morass that was a growing number of reports of mass animal deaths around the world. Enter the amazing tool that is Google Maps and lo, there is salvation. They have a map that shows all the various animal death events around the world along with a sidebar giving details. So I share with anyone out there who wants to see the big picture but can no longer do it in your head, the Google Maps “big picture” link. Just click here.
The Post – Weird Marine Monsters
January 6, 2011I found a neat blog that covers topics on the ocean, called Scuttlefish. The blog owner describes it as follows:
“The scuttlefish is a project by Brian Lam, celebrating the lovely, terrifying, powerful, mysterious, soothing, angry, calm, merciless, and awe inspiring sea. It has nothing much to do about technology.”
Even better, I was talking about the ocean census in yesterday’s blog entry, esp about how they counted things and the technology used. Well this gentleman covered the wonders that were some of the discoveries made in that census, and his post, The Census of Weird Marine Monsters by monkeyfist, has WONDERFUL pictures of just a few of the marine creatures found. If you want to see some of these close up, check out the article there.
The Post – An Unlikely Fish Count
January 5, 2011I often paint fish and undersea creatures. Squids, southern flounder, American shad, krill, just to name a few. I will paint many more. Hence I’m always on the lookout for great pictures. I don’t copy them but use them to inspire me, and to sometimes put together a composite image of a few creatures in a scene of my own making.
Also as a person who paints and loves the ocean and its life, I am always seeking news on its health, problems, successes. A recent topic of interest to me, was the recent (2010) completion of the Census of Marine Life. ( http://www.coml.org) It boggled my mind that someone could do this and I wondered how.
An article on Gizmodo recently appeared, that included a video on this very topic. As the video says, there are places in the ocean so remote they could not be explored, groups of fish so large they could not be counted, animals that travel so far they can’t be followed. If all that is true, how then did they do the Census of Marine Life for 10 years? The answer is revealed in this article and video. And you can find out what “OBIS” stands for. Just amazing work.
For even more info, check out www.coml.org . Also, there are some great books out on the subject. World Ocean Census (ISBN-13: 978-1-55407-434-1) I picked up the book and it has photographs that are just beautiful. It is the story of the census. There is another I’m waiting to receive done by National Geographic: Citizens of the Sea – Wondrous Creatures from the Census of Marine Life that looks just amazing in the creature photographs it contains. I can’t wait to get it!. …….I can never get enough of the ocean…….
The Post – The Challenge of Animal Cams….
January 5, 2011Animals are like kids – it’s a major challenge to get a good photograph of them. When I got this photo for “Hey Baby!” I must have shot almost 200 photos. Either he wasn’t positioned right, or he moved just as I clicked the shutter, the lighting didn’t highlight him right or I screwed up and used the wrong ISO or lens, or I used aperature priority when I should have used auto. Then of course, you can’t tell a fiddler crab “come on baby, work we me, yeah, flick your hair, turn, smile….” And of course, the times he was in perfect position waving his claw, I was just in the middle of something else with no camera handy and by the time I grabbed the tripod and set up the camera, he was doing something else. Suffice it to say tt was a major challenge getting one shot that he looked good in that was in focus, lit right etc.
I kept wishing I could have put my camera in the tank but too distracting and upsetting for Admiral Byrd and too awkward for me….not to mention I didn’t have one of those waterproof housings and my camera was too big for the tank.
I would have loved one of those smaller cameras you can just set up – a “fiddler cam.” Ultimately that is the answer to good pics I think….at least in terms of spontaneity and not upsetting him, but who knows if the kind of cam I could afford would focus well etc.
However, when I saw the following video I didn’t feel so bad. If professionals could have problems, I guess I didn’t do so bad. What I encountered was nothing compared to what the BBC group photographing polar bears went through, and they even had robotic cameras… For your viewing pleasure: Polar Bear video
I’ll just stick to fiddler crabs…. 🙂 have a nice day.
