The Smithsonian Institution is the place to "bee" on Monday, June 22.
The location: Baird Auditorium, National Museum of Natural History. The Smithsonian is located at the corner of 10th Street and Constitution Avenue NW, Washington D.C.
Thorp will discuss "Western Bumble Bees in Peril." Sydney Cameron and Jeff Lozier of the University of Illinois will examine "The Status and Trends of Midwestern and Southern Bumble Bees." Then Leif Richardson of the Vermont Department of Fish and Wildlife will cover "Bumble Bee Trends in Northeastern North America."
- Stephen Buchmann, University of Arizona, "USA Native Bee Diversity: Rarity, Threats and Conservation Ideals"
- Paul Williams, Natural History Museum, London, "A Global View of Bumble Bees and Their Conservation Status."
Michael Ruggiero of the Smithsonian Institution will moderate. He's the senior science advisor of the Smithsonian's Integrated Taxonomic System (ITIS).
Following the symposium, bumble bee experts and other scientists will continue to meet at the Smithsonian for the next two and a half days to discuss concerns about the declining bumble bee population.
The symposium is part of National Pollinator Week, which starts Monday, June 22 and continues through Sunday, June 28.
Thorp delivered a presentation on Franklin's bumble bee May 27, during one of the UC Davis Department of Entomology's noonhour sessions. Franklin's bumble bee, feared extinct or nearing extinction, is found only in one part of the world: southern Oregon and northern California. Thorp's talk was Webcast.
Thorp, a member of the California Academy of Sciences since 1986, says that the loss of a native pollinator "could strike a devasting blow to the ecosystem, economy and food supply."
Locally, we've noticed far fewer bumble bees than in past years. Last summer we spotted a few in the UC Davis Arboretum (see below). This is the yellow-faced bumble bee or Bombus vosnesenskii, the most common Califonria bumble bee.
Not so common any more.
Pollen-Packing Bumble Bee
If you like to take nature walks and lean against an occasional tree, you might rub shoulders with a red-eyed, red-shouldered bug.
On warm, springlike days, soapberry bugs are exploring their territories--and doing what comes naturally.
These predominately black-and-red bugs are seed feeders on plants but they're much more than that. Scientists consider them the evolutionary “canary in the coal mine.”
I captured these photos of soapberry bugs last Friday in the UC Davis Arboretum. UC Davis biologist Scott Carroll, biologist who studies basic and applied aspects of evolutionary biology, specifically soapberry bugs, considers them "good mothers and avid lovers." .
“Soapberry bugs are tame, pretty, good mothers, avid lovers, and among the best native guides to ongoing evolution on the planet," he writes on his under-construction Web site.
"They respond quicky to changes in the environment and can be good models for observing evolution in action."
They're also good photographic models./o:p>/u1:p>/o:p>/u1:p>/o:p>/u1:p>/o:p>/o:p>/u1:p>/o:p>
