Biodiversity--that's what it's at on Sunday, Feb. 12 at the University of California, Davis.
That's when four museums or centers that engage in education and research involving insects, vertebrates or plants will host open houses.
And folks will be amazed, officials promise.
The Bohart Museum of Entomology, the Museum of Wildlife and Fish Biology and the Botanical Conservatory will be open to the public from 1 to 4 p.m., while the Center for Plant Diversity will be open from 2 to 4 p.m.
"This will be a fun day where people of all ages can visit UC Davis and check out a number of our research and teaching collections," says Tabatha Yang, education and outreach coordinator for the Bohart Museum and Museum of Wildlife and Fish Biology. "Each collection is special and an important scientific resource. I think people will be amazed."
Yang calls it a "behind-the-scenes look at some top research collections."
"There will be staff and students on hand to answer questions and engage people. With Valentine's Day close by there will be some exhibits with a bent toward our love of the natural world, attracting a mate, and mating! But don't worry--it will be appropriate for all ages. For plants this means pollination and that ties back to insects and other animals like bats! "
The event is the first-ever on campus and may become an annual event. "The various collections have talked about doing a museum day," Yang said. "In early February, there is an annual Museum Day for the Sacramento area. This involves the zoo, the railroad museum and other attractions."
Theme of the Bohart Museum open house will be “Bug Lovin.’” The Bohart Museum, located at 1124 Academic Surge on California Drive, is home to more than seven million insect specimens; a live petting zoo (including Madagascar hissing cockroaches and walking sticks; and a gift shop. The director is Lynn Kimsey, professor of entomology at UC Davis. The museum is affiliated with the Department of Entomology.
The Museum of Wildlife and Fish Biology (MWFB) is a vertebrate museum dedicated to education, outreach, conservation, and research. It is located in 1394 Academic Surge, California Drive and is part of the Department of Wildlife, Fish and Conservation Biology. MWFB is managed by curator Andrew Engilis, Jr. and collections manager Irene Engilis.
The UC Davis Botanical Conservatory, directed by Ernesto Sandoval, is a 3,600 square-foot greenhouse complex located north of Storer Hall on Kleiber Hall Drive. Its mission "to inspire, facilitate, promote and engage our visitors with an understanding and appreciation of plants, their diversity and the pivotal role they serve in the environments where they are found," Sandoval says. The Botanical Conservatory is part of the Plant Biology Section, Department of Plant Sciences. The conservatory includes more than 3,000 live specimens from 150 families.
The Center for Plant Diversity, directed by Dan Potter of Plant Sciences, is located in 1026 Sciences Laboratory Building, near Briggs and Storer halls. Part of the Department of Plant Sciences, it houses the J.M. Tucker and Beecher Crampton Herbaria. "We are going to have plant pressing and mounting demonstrations as well as tours," says curator Ellen Dean.
Feb. 12 also marks the birthday anniversary of naturalist Charles Darwin (1809-1882). Yang pointed out that "Darwin was inspired by exploring and collecting plants and animals from all over the world. This connection to nature and curiosity is what fueled Darwin's research. Our collections can inspire that same sort of curiosity and questioning.”
Yes, it promises to be an amazing day!

A sure sign that winter is nearly over: when the flowering quince bursts into bloom, attracting a flotilla of foraging honey bees.
Actually, the bees began "inspecting" the flowering quince in the bud stage. "Hurry, open up!" the bees seemed to urge. "We have to start feeding our colonies."
Flowering quince (genus Chaenomeles, family Rosaceae) is an ornamental plant that's delightful to see. Who doesn't admire the soft pink blossoms and the comforting hum of bees buzzing around with heavy loads of yellow pollen?
The nation's bees, though, are still in trouble. Overwintering losses are still around 30 percent as in the years past, honey bee experts say. Bees are still suffering from colony collapse disorder (CCD), a mysterious malady characterized by adults bees abandoning the hive. CCD is thought to be the result of multiple factors, including pesticides,pests, diseases, malnutrition and stress.
As Christi Heintz, executive director of Project Apis m. (as in Apis mellifera), told the Almond Board of California at its meeting in December: “Colony losses are not quite as acute as in previous years, mainly as a result of improved management, but overwintering losses still hover around 30 percent, an unsustainable rate of loss.”
Heintz, who is the Almond Board Bee Task Force liaison, listed seven areas for best management practice (BMP) development: bee nutrition, pest control/varroa, disease control/nosema, hive mangement/equipment, colony management, business management, and BMPs for almond growers/bee rentals.
You can read the entire BMP article in Bee Culture.
Project Apis m. or PAm, serves an important role. Beekeepers and orchardists established PAm in December 2006, as a "New Vision" to fund honey bee research on managed colonies, according to its website. The organization's goal: "to fund and direct research to improve the health and vitality of honey bee colonies while improving crop production. Emphasis is placed on research studies that have realistic and practical usefulness for beekeeping businesses."
"PAm brings together representatives of the American Honey Producers Association (APHA), the American Beekeeping Federation (ABF), the National Honey Board (NHB), California State Beekeepers Association (CSBA), and California almond farmers. PAm includes representatives from both the pollination and crop production enterprises."
Together we can all do our part to help save the bees. The first step: awareness.

What do butterflies tell us about tropical diversity?
Take it from an expert.
Tropical ecologist Philip DeVries of the Department of Biological Sciences, University of New Orleans, will discuss the topic at his lecture on Thursday, Feb. 9 at the University of California, Davis.
His presentation, sponsored by the College of Biological Sciences' Storer Life Sciences Endowment, is at 4:10 p.m. in 2 Wellman Hall. Professor Phil Ward of the UC Davis Department of Entomology is his host.
Free and open to all interested persons, the lecture is sparking a lot of interest, and rightfully so.
DeVries focuses his research on insect ecology and evolution, especially butterflies. A native of Detroit, Mich., he received his doctorate in zoology from the University of Texas, Austin, in 1987.
Highly honored, DeVries has received fellowships from the MacArthur Foundation, the Guggenheim and Dodge foundations, and the Smithsonian Institute. He is not only a noted researcher and ecologist, but a writer, scientific adviser and photographer.
If you listen to his piece on YouTube (uploaded in 2008), you can see, hear and feel the excitement in his voice as the long-tongued hawk moth, Morgan's Sphinx (Xanthopan morgani) pollinates Darwin's orchid (Angraecum sesquipedale) one night in a Madagascar rain forest. Truly amazing!
Background of the moth and orchid: Naturalist Charles Darwin examined the orchid in 1862 and famously predicted in his book Fertilisation of Orchids that there must be in existence a moth with a long-enough tongue (proboscis) to be able to pollinate it. The orchid's "nectar spur" measures about 12 to 14 inches long. The moth itself was discovered in Madagascar in 1903--correctly proving Darwin's prediction of its existence-- but no one saw it pollinate the orchid until DeVries headed out to the rain forest with his camera equipment. Since pollination occurs only at night, DeVries used infrared light (invisible to the moth) to capture the scene.
Jerry A. Coyne, a professor in the Department of Ecology and Evolution at the University of Chicago, blogged about the spectacular video in "Why Evolution Is True."
"The video," Coyne wrote, "was made in Madagascar by a friend of mine, Phil DeVries from the University of New Orleans, a remarkable—and, as you’ll see, intrepid—naturalist, and author of the two-volume Butterflies of Costa Rica and their Natural History."
"It’s really lovely to see how excited Phil gets when he finally sees the pollination," wrote Coyne. "Those are the juicy moments that every naturalist lives for."
Yes, indeed! It's something you never expect to see--and hope to see again.

In a pre-Valentine's Day event, officials at the Bohart Museum of Entomology at the University of California, Davis, are planning a Bug Lovin' theme for their next open house. It will be a lovefest of bugs!
The event, free and open to the public, will take place from 1 to 4 p.m., Sunday, Feb. 12 at the museum, located at 1124 Academic Surge on California Drive.
The Bohart, home of more than seven million insect specimens, also houses a "live petting zoo" (think Madagascar hissing cockroaches and walking sticks) and a bug-themed gift shop, where you can buy Valentine's Day presents for your sweetie. Among the many items: jewelry, t-shirts, sweatshirts, insect candy, coffee cups, posters, insect-collecting equipment and the like. (Be sure to check out the California dogface butterfly earrings crafted by UC Davis entomology graduate student Emily Bzdyk. Items from the gift shop can also be ordered online.)
The open house will be part of "UC Davis Biodiversity Museum Day." Also open that day from 1 to 4 p.m. will be the Museum of Wildlife and Fish Biology and the Botanical Conservatory. The Center for Plant Diversity will be open from 2 to 4 p.m. (Download directions)
What else is Feb. 12 known for? Scientists celebrate the birthday anniversary of Charles Darwin (Feb. 12, 1809-April 19, 1882).
With four open houses planned on Feb. 12, it's a good time to head over to the campus and learn about biodiversity.

Last summer we spotted what appeared to be the red-backed jumping spider, Phidippus johnsoni (famiiy Salticidae), stalking native bees and honey bees in our yard.
Its iridescent green chelicerae, which characterizes many species in the genus, literally glowed.
It wasn't a good hunter. It missed its prey time after time.
So, it should be interesting when Damian Elias, assistant professor, Department of Environmental Science, Policy and Management, UC Berkeley, comes to UC Davis on Wednesday, Feb. 8 to speak on "Multimodal Communication in Jumping Spiders" from 12:10 to 1 p.m., Wednesday, Feb. 8 in 122 Briggs Hall.
"Animals use a variety of senses to navigate the world," Elias says. "While humans are adept at sensing the world through visual, auditory, and olfactory (smell) information, some animals use senses that are imperceptible to human observers. The vast majority of life on the planet uses vibrations transmitted through solid objects (substrate-borne vibration) to communicate and up until recently, this crucial aspect of animal biology was completely unknown."
The jumping spider he is currently focusing on is Phidippus clarus.
Elias, who received his doctorate in neurobiology and behavior from Cornell in 2005, says he uses behavioral ecology techniques to study different aspects of communication. In particular, he is interested in questions regarding sexual selection, mating system evolution, signal design and responses to population, ecological, and environmental variation.
If you look on YouTube, you'll see an excellent macro video of the same jumping spider, Phidippus clarus, that Damian Elias studies. It's the work of Oklahoma artist Thomas Shahan (who also teaches macro photography in the popular BugShot workshop).
And, if you think that's amazing, check out the even more spectacular images of jumping spider photos on Shahan's website.
