In search of marsupials

Australia is a perfect place to find examples of adaptive radiation. Find yourself a kangaroo or a wombat or a koala or any other marsupial… and there you go, adaptive radiation.

Alas, at this time of year, in the areas near my home, I don’t see many marsupials. Many of them nocturnal, which is one issue. The other issue is that I’m not out at dusk and dawn in winter, when you also have a good chance of seeing a kangaroo.

So I’ve been keeping my eye out, but haven’t seen any yet. I haven’t been riding all that much either. Work is beyond ridiculous in hours and stress – which has really impacted my energy levels and health. If it doesn’t ease up soon, I won’t last past Christmas. So I just haven’t had the energy to ride. You know things are bad when I can’t summon forth the energy to pedal even a bit.

So here are some pics from some recent rides while out looking for kangaroos. No adaptive radiation, but we covered a bit more of the electromagnetic spectrum and did some radial structure that seems to be what most people have captured for radiation this month.

See some sun rays trying to peek through? After a quite dry July, we’ve been getting a bit more rain in August (which we desperately need).
Here is some radiating action – we have heaps and heaps of windmills around where I live. This one looks pretty new – the tank definitely is.
We have covered mobile phone towers and that wave frequency, but we have not yet done radio waves. So here is a mobile phone tower (left) and a comms radio tower (emergency services/UHF) on the right. And some cows and a dead tree. Radio waves are a type of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than infrared light. Radio waves have frequencies as high as 300 gigahertz.
Some more radiation from the high voltage power lines. These ones are buzzing – you can hear those electrons moving!

Fortunately, we have not been ill with things that would get us gamma rays on the electromagnetic spectrum. And the chest x-rays, echocardiogram and ultrasounds last year were all digital images, so nothing to take a bike photo with now (and who wants to see the inside of Em anyway). But we could get a bit more of the electromagnetic spectrum with Verne riding around the microwave. Just so you know, he refused to be radiated in there despite my pleas for what a good video it would make. He did demand I clean up the pumpkin soup I spilled on the glass bit, though. He doesn’t want you to think we are feral.

    Adaptive radiation – too brilliant. I’d forgotten that was even a thing!

      There are so many bird examples of adaptive radiation, I thought you would have gone that route earlier!

    Your critters crack me up! Get some rest. You’re probably too young, but my health improved tremendously after I retired.

      Glad the guys could give you a smile. I’m way to young to retire, but I have always planned to take time off after this contract. I likely won’t make the end of the contract though. Since I got West Nile in 2017 and never got well, people with experience with post-viral issues have told me to take 6 months off to rest and let my immune system heal. I’ve not done that yet, and I think my body is going to force me to pretty soon. I can afford it, but the timing is terrible.

    Adaptive radiation, that’s the first time I’ve heard of that, and I’m a smug Know-it-all. Left a steel spoon in my meal in the microwave for 50 seconds recently, still works.

      Spoon or microwave? 😉

        All the sparks flying would have made a good challenge photo — maybe Lednar could try it again assuming the spoon still works. 😉

      Kermit has some wires in his arms and legs, but Verne is metal free. Still didn’t want to get in the microwave. I don’t think it’s claustrophobia… he is a turtle with a shell, after all.

    Sorry to hear work is so stressful for you. I hope you start feeling better soon! Great photos!

      Thanks for the well wishes. Ramming through once in a generation reforms to strict deadlines in the middle of a pandemic with everyone trying to work from home is really NOT conducive to anyone’s health, let alone my poor, fragile immune system. Stay safe on your travels!

    Back years ago, I got electromagnetic radiation from Australia in the form of shortwave radio — lots easier to listen to Radio Australia now on the internet.
    Never heard of adaptive radiation — I really *should* have gone to class more often??
    Wombats are without question my favorite Aussie animal!

    • By: The Navigator Posted: August 20, 2020

      Wombats are Nigel and I’s favourite marsupial, too, by a large margin. Koalas in second place.
      Yes, internet radio doesn’t quite take as much effort as short wave – a dying hobby? I have a friend who is really into doing SOTA trips in Colorado though. Here’s the UK version: https://www.sota.org.uk/
      I was nerdy enough that I remember being so enthralled with Darwin’s work on the birds in the Galapagos when I read his works in high school as part of a research project in an Environmental Biology class at the clever kids high school. So I’m sure you’ve come across adaptive radiation before, but it was long enough ago you don’t remember. You are very clever and know so much, I’m sure it’s in your brain somewhere… or maybe you just remember speciation or convergent/divergent evolution instead 🙂

        Speciation I have heard of. . . . . . Clever and knowledgeable??? Obviously, you have me confused with someone else! 🙂

        Numbats are my favourite. some local bias
