Biodiversity in the Honey Bee Haven

When the half-acre Häagen-Dazs Honey Bee Haven is implemented by the Harry H. Laidlaw Jr. Honey Bee Research Facility at UC Davis later this year, honey bees won't be the only ones enjoying the garden.

Expect to see butterflies, bumblebees and other insects.

Remember the project? Last December Häagen-Dazs ice cream committed $125,000 to the UC Davis Department of Entomology for the bee haven. A Sausalito team-- landscape architects Donald Sibbett and Ann F. Baker, interpretative planner Jessica Brainard and exhibit designer Chika Kurotaki--won the design competition, which drew 30 entries. One was submitted from as far away as England.

The key goals of the garden are to provide bees with a year-around food source, to raise public awareness about the plight of honey bees and to encourage visitors to plant bee-friendly gardens of their own.   

We’re all eagerly looking forward to the garden, which will be dedicated in October.

Meanwhile, scientists at the Laidlaw facility plan to examine the diversity of insects already there. One insect we saw there last week was a soapberry bug on a flowering almond tree. 

So bees, butterflies, bumblebees and soapberry bugs.

Among others.

Lots of others.

The Humble Bumble Bee

A sure sign of approaching spring...

As the cold weather subsides, out come the overwintering queen bumble bees. They're gathering nectar and pollen, building their nests and laying eggs.

Lynn Kimsey, professor and chair of the UC Davis Department of Entomology and director of the Bohart Museum of Entomology, found a young queen bumble bee (Bombus melanopygus) on campus yesterday.

The confused queen managed to fly into Briggs Hall, home of the UC Davis Department of Entomology.

These particular  bees, native to North America, are nicknamed  "the orange-rumped bumble bees." They're basically your fuzzy-wuzzy, yellow-banded black bumble bees. 

Last year UC Davis entomologist Robbin Thorp tended a  nest of Bombus melanopygus  on the Harry H. Laidlaw Jr. Honey Bee Research Facility grounds at UC Davis. The story behind the story: an area resident was seeking a temporary location for the bumble bees, which were nesting in his birdhouse.  Thorp obliged.

The photos below: 

Kimsey's queen bumble bee (which rates a solid 10 on a scale of 1 to 10 for fuzzy-wuzziness) and a bumble bee ready to take flight from  the birdhouse.  The bumble-bee-in-the-birdhouse photo, taken Feb. 29, 2008, received an online presence when the North Carolina State University Museum asked to borrow it to illustrate some text.

All hail the humble bumble bee...ever beautiful and ever resourceful.

A Wonderful Gift

It's a wonderful gift.

Häagen-Dazs last December committed $125,000 to the UC Davis Department of Entomology to establish a bee friendly garden at the Harry H. Laidlaw Jr. Honey Bee Research Facility, and today, the winner of the design competition takes center stage.

The winner...drum roll, please...a team from Sausalito.

The four-member team created a series of interconnected gardens with such names as Honeycomb Hideout, Nectar Nook and Pollinator Patch to win the international competition, which drew 30 entries--one from as far away as England.

Landscape architects Donald Sibbett and Ann F. Baker, interpretative planner Jessica Brainard and exhibit designer Chika Kurotaki submitted an amazing design that will be brought to life this summer on a half-acre site on the Laidlaw facility grounds. (View the 21-page design on this page

.The key goals of the garden are to provide bees with a year-round food source, to raise public awareness about the plight of honey bees and to encourage visitors to plant bee-friendly gardens of their own.   

It all started in February 2008 when Häagen-Dazs  launched a national campaign to help the honey bees. They donated a total of $250,000 for honey bee research at UC Davis and Pennsylvania State University; launched an educational Web site, formed a scientific advisory committee, and created a new ice cream flavor, Vanilla Honey Bee.

And now comes the Häagen-Dazs Honey Bee Haven. Or bee heaven.

 

 “We’ll not only be providing a pollen and nectar source for the millions of bees on campus, but we will also be demonstrating the beauty and value of pollinator gardens,” said design competition coordinator Melissa “Missy” Borel, program manager for UC Davis’ California Center for Urban Horticulture. “My hope is that it will inspire everyone to plant for pollinators.”

 

 “The winning design fits beautifully with the campus mission of education and outreach, and it will tremendously benefit our honeybees at Bee Biology,” said Lynn Kimsey, professor and chair of the UC Davis Department of Entomology and director of the Bohart Museum of Entomology. “The garden will be a campus destination.”

 

And it’s a close destination for the 50-some colonies at the Laidlaw facility and for neighboring bees,  native pollinators and other beneficial insects.

 

Worker bees live only four to six weeks during their peak season. Now they won’t have far to travel to gather nectar, pollen and propolis in an environmentally friendly garden filled with some 40 different varieties of flowering plants.

Meanwhile, honey bee research  to determine what's causing the declining bee population continues unabated.

 

Honey bees will never know the source of their gift, but the people who support them, care for their needs and admire them will.

 

It's a wonderful gift.

Diggin' Darwin Day

It promises to attract a large crowd.

The UC Davis Center for Population Biology is planning a Darwin Day on Monday, Feb. 23.

If it sounds like a belated birthday party, it is and it isn't.

Darwin Day, billed as "a global celebration of science and reason," is held on or around Feb. 12, the birthday anniversary of evolutionary biologist Charles Darwin, according to a specially set up Web site dedicated to him and his work.

The Davis celebration, free and open to the public, begins at 7 p.m., in the Varsity Theatre, 616 Second St., Davis.

The one-hour event will include two public lectures, a birthday cake, and insect and fossil exhibits.

The event is sponsored by the Center for Population Biology and also involves the Department of Entomology, the Department of Geology, the Bohart Museum of Entomology and the Museum of Wildlife and Fish Biology.

“This is a great synergy between the Center for Population Biology, the Department of Entomology, the Department of Geology, the Bohart Museum of Entomology and the Museum of Wildlife and Fish Biology,” said Tabatha Yang, education and outreach coordinator for the Bohart Museum and the Museum of Wildlife and Fish Biology.

Presenting the public lectures will be evolutionary ecologist Maureen Stanton, chair and professor, Department of Evolution and Ecology, and evolutionary biologist Jonathan Eisen, who maintains a lab in the the UC Davis Genome Center and holds appointments in the Departments of Medical Microbiology and Evolution and Ecology. He also writes a blog, The Tree of Life.

Stanton will discuss “The Evolution-Intelligent Design Controversy: What Lessons Does It Offer about the Nature of Legitimate Science?” Of her topic, she says: “There is a great deal of public misunderstanding about science, and yet scientific literacy is more critical now than ever before. In this talk, I'll discuss how evidence is used in fundamentally different ways by doctrinarians and scientists, using evidence for evolution to demonstrate that difference. Science is important, but its sphere is limited only to natural phenomena, leaving abundant room for the reconciliation of science with faith.”

Eisen’s topic is “Evolutionary Biology is a Valuable and Practical Tool.” He elaborates:  "Evolution is frequently interpreted as a science of the past. However, an evolutionary perspective is a powerful and irreplaceable tool in studying and understanding the world around us. I will give examples of how information on evolution plays critical roles in subjects ranging from drug and vaccine development, forensics, conservation biology, and human medicine.”

Graduate students in the Center for Population Biology graduate students organized the free lectures.

UC Davis entomology graduate students Andrea Lucky, Sara Diamond and James Harwood will show live insects from the Bohart Museum of Entomology. The museum houses seven million insect specimens, but also includes live ones, such as Madagascar hissing cockroaches and walking sticks.

The Darwin Day event is one of more than 700 celebrations occurring globally--on or around Feb. 12.

Midge Madness!

Midge madness?

Yes, and Briggs beckons.

 

"Midge madness" will occur from 12:10 to 1 p.m. Wednesday, Feb. 25 in 122 Briggs Hall on the University of California, Davis, campus.

 

That's when Claudio Gratton of the Department of Entomology, University of Wisconsin, Madison, will discuss "Midge Madness! Quantifying Linkages Between Lake and Land" during the eighth of  10 winter seminars sponsored by the UC Davis Department of Entomology.

 

You've probably heard of the billions of midges--small two-winged flies--that swarm periodically at Lake Myvatn, Iceland. An article published last March in Science Daily indicated that at their peak, "it is difficult to breathe without inhaling the bugs, which hatch and emerge from the lake in blizzard-like proportions. After their short adult life, their carcasses blanket the lake, and the dead flies confer so much nutrient on the surrounding landscape that the enhanced productivity can be measured by Earth-observing satellites."

 

Enter Claudio Gratton, who studies food web ecology, insect-plant-virus interactions, herbivore-natural enemy interactions, invasive species, biological control, and soil food webs. "Recent empirical and theoretical models," he says, "indicate that the dynamics within food webs are often influenced by resources coming from outside of the focal food web, also termed a 'spatial subsidy.' "

 

Gratton describes Lake Mývatn as "a eutrophic lake in Northern Iceland with an exceptional natural phenomenon of large-scale chironomid midge (aquatic insect) outbreaks that occur every 5-7 years. The densities increase over four orders of magnitude."

By the way, Lake Myvatn means "midge lake" in Icelandic.

"We used this lake and the surrounding landscape to examine the effect that large-scale spatial subsidies have on terrestrial arthropod food webs," said Gratton, who received his doctorate in entomology from UC Berkeley in 1997.   "Our studies have shown that by moving from lake onto land, the midges act as two types of subsidies."

"First, they can transfer as much as 70 kg N and 10 kg P ha^-1 yr^-1 to a 100-200m wide area surrounding the lake, resulting in increased plant quality, biomass and increased detritivore and herbivore abundance."

"Second, they subsidize the food base of the natural enemies (mainly spiders) on the terrestrial shoreline.  As a result, food web interactions on land are significantly affected by the adjacent lake ecosystem, effects that have the potential to propagate over the long-term, even after midge abundances subside."

 

Want to learn more about the mighty midges of Myvatn? Attend Gratton's presentation next Wednesday. UC Davis Department of Entomology hosts are Peter Epanchin of the Graduate Group in Ecology (he's in professor Sharon Lawler's lab), and professor and insect ecologist Jay Rosenheim.
