Monarch Population in California 'Booming'
If you missed it, you should to listen to what longtime butterfly researcher Art Shapiro, distinguished professor of evolution and ecology at the University of California, Davis, says about California's monarch butterfly population. He's been monitoring the butterfly populations in Central...

Bats save walnut growers money on pest control
California farmers produce most of the nation's walnuts, about 500,000 tons of walnuts on 290,000 acres, with an annual crop value of $1.8 billion.
Long, who works on field crops and pest control in Yolo, Sacramento and Solano counties, noted there are 250,000 bats living under the Yolo Causeway alone that could be employed for pest control.
When asked how she knows that the nocturnal animals are eating the damaging pests, Long explained that she examines the guano to identify the insects they've eaten. "Bats have very shiny poop," she said, because their fecal matter is full of insect exoskeletons.
Long, who has studied the design elements of bat houses, brought a sample of a bat house to the studio. She said the box should be placed in an area that gets afternoon shade and at least 10 feet off the ground to protect the bats from cats and dogs.
Long also talked about the Black Rock Desert trilogy, a series of educational children's books about the adventures of a boy and a pallid bat that she has authored.
For more information about Long's bat project, see her blog post Bats in the belfry? No, bats in walnut orchards.
Long will be discussing her bat research with the Capital Science Communicators group tonight at G Street Wunderbar in Davis. She will bring specimens of common bat species for people to see and touch. The talk is part of UC Davis' Science Café series and is a free event that's open to the public.
