Richard Nelson and Moose in Alaska on NPR

I just listened to this super piece on NPR by Richard Nelson about moose in Alaska.  I was on a bagels run so I missed the beginning.  But I stayed in the car for about 5 minutes after I got home so I could hear the end of it.  It was a classic NPR moment: I was transported by radio from our driveway in New England to someplace in Alaska.

Meeting Alan Templeton at Wash U

I met Alan Templeton on Sunday at my father’s birthday party.  He is the Charles Rebstock Professor of Biology at Washington University in St. Louis, Mo.  We had an interesting discussion about his work and my interests in Science and Society despite the short time and my urge to follow a number of really, really interesting tangents.

Most of our conversation was concentrated on his work with collared lizards in the Ozark Mountains of Missouri.  Apart from being very cute, these lizards are interesting because, together with several other rare species of plants and animals, they live in a cool and rare habitat in the high Ozark Plateau called a ‘glade habitat.’  Although I am not sure I really understand what it is, it sounds a bit like islands of isolated desert with thin, poor topsoil, exposed rock, grasses, and some shrubs separated by dense hardwood forests with thick undergrowth. It seems that this glade habitat is shrinking, a series of isolated and geographically discontinuous, small islands where both plants and animals loose genetic diversity and face extinction.  Wildfires played an important role in maintaining this habitat historically:  the “islands” were larger, connected by migration corridors and surrounded by a savannah landscape, much more open than the Ozarks we see today.

Of course, I asked him my question:  “How do you know?”
