You may have heard of locavores — people who prefer to eat food grown or raised locally — or freegans — people who dine on wasted food. Now there’s a new food movement that advocates curbing the growth of invasive species by eating them. Invasivors prey upon species that are taking over the established habitats of other animals. Jackson Landers is an adherent of this movement:As the Locavore Hunter, based in Virginia, he teaches urbanites how to hunt and butcher deer. He has branched out from the locavore life to invasives, and lionfish are one target. But as he has pushed the envelope of the invasivore approach, he has hunted and eaten feral pigs, two species of iguana, armadillos, starlings, pigeons and resident Canada geese. He says that all of these activities will be chronicled in a book, “Eating Aliens,” and perhaps a television show as well.
Mr. Landers, who grew up in a vegetarian household, taught himself to hunt. He believes that eating invasives can have a real effect. “When human beings decide that something tastes good, we can take them down pretty quickly,” he said. Our taste for passenger pigeon wiped that species out, he said. What if we developed a similar taste for starlings?
Kathryn Aurora Gray knew a superstar when she saw one (and with a middle name like that, how could she not?). The 10-year-old girl from New Brunswick, Canada, just became the youngest person to ever to find a supernova (with a little help from astronomer dad):Since a supernova can outshine millions of ordinary stars, it can be easy to spot with a modest telescope — even in a distant galaxy such as UGC 3378, which is about 240 million light-years away. The trick is to check previous images of the same location to see if there are any changes. That’s what Kathryn was doing for the images of the galaxy taken by her father.Nancy Atkinson of Universe Today has the story: here.
“You hold the wing up against the light, so you can see the veins,” said study co-author Daniel Janzen, an evolutionary ecologist at the University of Pennsylvania. “If you’re looking through a microscope, you try to get a clear view behind the wing. It’s the antithesis of getting wing color.”This study looked at the wings of wasps and flies, and the team believes they may find similar results in other orders of insects.
The researchers studied wings under microscopes, against black backgrounds. But once Janzen, who breeds wasps for his research on caterpillar-parasite symbioses, started to look, colors could be seen by the naked eye as wings passed over insects’ black bodies.
