Are you ready for the Great Bee Count?
It's happening Saturday, Aug. 11.
You're encouraged to be a "citizen scientist" and count the bees in your backyard or garden over a 15-minute period and to watch or listen to a national online video broadcast at http://www.yourgardenshow.com/bees between 8 and 10 a.m., Pacific Time. (Those are Pacific times; consult the website for the schedule in other time zones.)
Brady, a cultural entomologist and journalist from Davis, describes the event as a special “BEE” broadcast (Bee curious, Bee aware and Bee a good neighbor).
The Great Bee Count also will feature Brady’s footage of the UC Davis Department of Entomology's Häagen-Dazs Honey Bee Haven on Bee Biology Road.
The online video broadcast also will include a question-and-answer session moderated by Ian Cook.
What's it all about? The program is about creating a discussion and activity forum for new or experienced beekeepers, and “all of us who would like to learn more about bees and bee conservation, pollinators and backyard citizen science,” according to the YourGardenShow website.
The schedule (Pacific Time), subject to change:
8 a.m. – 8:30 a.m.

You may remember Brady for several reasons.
(1) Last year he hosted the first-ever Bee-A-Thon, a global online marathon dedicated to raising awareness about honey bees and other pollinators.
(2) He's an innovator in the emerging field of cultural entomology
(3) He's the creator of the popular radio program, Insect News Network (.com), now based in Davis. It airs every Wednesday from 4 to 5 p.m on KDRT 95.7 FM.
A founding member of the Biomimicry Guild Speakers Bureau, Brady has lectured at seven universities across India. More locally, he co-founded the San Francisco Bay Area Green Tours. And now, he's authoring the Wikipedia entry for cultural entomology and a book entitled "Humvees and Honeybees: An Introduction to Cultural Entomology."
His passion for entomology extends to his given name, "Emmet."
It means “ant” in Gaelic.

Just drop by the Davis Public Library next Thursday night.
Pollination ecologist Neal Williams, assistant professor of entomology at UC Davis, will present a public lecture on “Promoting Native Bees for Gardens, Farms, and Native Plants” at the Davis Botanical Society meeting on Thursday night, May 10 in the Davis Public Library, 315 E. 14th St.
Williams, to speak from 7 to 8 p.m., will discuss native bee biology and diversity in the Capay Valley, how bees interact with plants, and the challenges facing native bees as they respond to landscape change in Yolo County. Drawing from his studies on the impact of native plant selections in the re-diversification of agricultural landscapes, Williams also will tell his audience how habitats can be enhanced using native plants.
“Our beautiful state has diverse and unique plants and animals, with many found nowhere else in the world,” said Botanical Society spokesperson Ellen Dean, curator of the UC Davis Center for Plant Diversity. “This is true of our native bee species, some of which have never been named by science. If you have wanted to find out more about the relationship between native bees and California plants, you are invited to come to a free public lecture.”
Williams, who joined the UC Davis Department of Entomology in 2009, was a featured speaker at the International Symposium on Pollinator Conservation, held last January in Fukuoka, Japan. He explored agricultural landscape change and the role of bee life history in predicting and understanding responses of bee communities.
A native of Madison, Wisc., Williams studied botany, history and philosophy of science in 1990-91 at Edinburgh University, Scotland, before receiving his bachelor of science degrees in botany and zoology from the University of Wisconsin, Madison in 1992. He received his doctorate in ecology and evolution in 1999 from the State University of New York, Stony Brook (SUNY-Stony Brook).
And, if you're interested in joining the Davis Botanical Society, the group has scheduled its annual meeting and election of officers at 6:45 p.m., just prior to Williams’ talk.
Parking in the library parking lot is free. Further information on the Davis Botanical Society is available from Ellen Dean or Jean Shepard at the UC Davis Center for Plant Diversity at (530) 752-1091.

Bee specialists Neal Williams and Eric Mussen of the UC Davis Department of Entomology are among those quoted in a comprehensive news story, "Hives for Hire," published March 3 in the Los Angeles Times.
"Almond trees are exploding with pink and white blossoms across the vast Central Valley, marking the start of the growing season for California's most valuable farm export," wrote LA Times reporter Marc Lifsher in the lede.
Indeed they are.
This is a $3-billlion-a-year industry and the acreage amounts to some 750,000 acres. Approximately 2.6 million colonies from across the country are trucked into California for the almond pollination season.
"Without the honey bees...the (almond) industry doesn't exist," Williams told Lifsher. "We need those bees. We need them to be reliable, and we need them at the right time."
Williams, a pollination ecologist who joined the UC Davis Department of Entomology faculty in 2009, is an expert on bees, especially native bees (honey bees are not native; they were brought here in the 1600s by the European colonists).
An assistant professor of entomology, Williams heads a busy lab of graduate students and post-doctoral students. He just returned from Fukuoka, Japan, where he was one of the featured speakers at the International Symposium on Pollinator Conservation.
Also quoted in the LA Times piece was honey bee guru Eric Mussen, Extension specialist with the UC Davis Department of Entomology since 1976.
Mussen discussed bee health with Lifsher and the collapse disorder (CCD), the mysterious malady characterized by adult bees abandoning the hive. Mussen regularly provides updates about bee health to national and state bee conferences and at beekeeper association meetings. Mussen writes the bimonthly from the UC apiaries and the periodic Bee Briefs, both available free on the UC Davis Department of Entomology website.
So, what's the word? Mussen tells his constituents that beekeeping is a complex issue, as is CCD, which he attributes to multiple factors, including pests, parasites, pesticides, diseases, malnutrition and stress.
Yolo County-based beekeeper Henry Harlan of Henry's Bullfrog Bees, who maintains some 2400 hives, said it well when he told Lifsher that beekeeping is an inexact science. "If you meet a beekeeper who says he knows it all, his bees will probably be dead next year."
Indeed, it's a sinking feeling to open your hive at winter's end and find it empty.

If you're interested in pollen and pollinators, you'll want to attend the UC Davis Department of Entomology seminar at 12:10 p.m., Wednesday, Feb. 1 in 122 Briggs Hall.
That's when T’ai Roulston, research associate professor and curator, State Arboretum of Virginia, will speak on "Pollen as a Resource for Pollinators: What Governs Quality?"
Pollen is a bee's protein. Nectar is a bee's sugar or carbohydrate.
T'ai Roulston will be speaking specifically on pollen. "Lab work using the sweat bee Lasioglossum zephyrum has shown that protein concentration of pollen may dramatically influence offspring size," he says.
"T'ai's work on native bees and insect-plant interactions includes pollination biology, foraging ecology, nesting biology, life-history as well as some work on multi-trophic interactions," said host Neal Williams, assistant professor. (Williams is currently in Japan to present a lecture at the International Symposium on Pollinator Conservation, set Jan. 27-29 in Fukuoka.)
Roulston says on his website:
"My primary research area is plant-pollinator interactions, which I study through field and laboratory approaches." These include
1. Studies of pollen chemistry, particularly protein, to characterize the diversity of pollen nutrient rewards and their effects on pollinator host plant choice and larval development;
2. Specialization/Generalization in plant-pollinator interactions
Other research areas include endangered species conservation, habitat fragmentation, foraging behavior and nestmate recognition in social Hymenoptera, and the impact of exotic species on native organisms.
Coordinating the UC Davis Department of Entomology winter seminar series are assistant professors Louie Yang and Joanna Chiu.
If you can't make it to the the lecture, Professor James R. Carey plans to video-record it. It will be posted in about two weeks on UCTV.

Pollination ecologist Neal Williams, assistant professor of entomology at UC Davis, will be one of the featured speakers at the International Symposium on Pollinator Conservation, to be held Jan. 27-29 in Fukuoka, Japan.
His talk will explore agricultural landscape change and the role of bee life history in predicting and understanding responses of bee communities. The conference, sponsored by the Japan Society of the Promotion of Science and themed "Conservation and Sustainable Use of Pollinators: Towards Global Assessments," will take place on the Hakozaki campus, Kyushu University.
Williams is the only invited speaker from California. (See his lab research)
“Bees provide a critical ecosystem service for humanity through their pollination of crops worldwide,” said Williams, who will speak on “Bee Life History and Resource Distributions Determine Population and Community Responses to Agricultural Landscape Change.”
“There is increasing recognition of the contributions of wild species to crop pollination and their role in sustainable pollination into the future. The persistence of wild bee species depends on the availability of essential nesting sites and forage resources within the landscape. Agriculture management can profoundly change the abundance and distribution of these resources over time and space."
“Because bee species differ in specific nesting and forage requirements, there is the potential for land transformation to filter wild bee communities based on such ecological traits,” Williams said. “I will present two separate studies from central California exploring the role nesting and forage resources in determining bee responses to agricultural intensification. The first study explores the effects of bee life history traits and resource distributions on observed changes in bee communities between semi-natural and farmland components of an agricultural landscape.
“I will use a combination of empirical data sampled over multiple landscapes and spatial modeling of bee communities to reveal the relative importance of forage and nesting resources to bee responses. The second study focuses on the bumble bee Bombus vosnesenskii. I will use empirical data on bumble bee colony performance and a spatially-explicit model of floral abundance to quantify the importance the forage-resource landscape in determining worker and queen production.”
Williams pointed out that “the abundance of forage strongly affected worker production; however, it was most sensitive to early season resources. Spatio-temporal variation in the resource landscape across the season reduced the overall effect of the forage landscape on queen production. Nonetheless consistent forage resources are key to the persistence of bumble bee populations in this region.”
