If a queen bee were to celebrate Mother's Day (and she won't because she's too busy laying eggs), what a crowded festivity that would be.
Bee breeder-geneticist Susan Cobey of Washington State University, former manager of the Harry H.Laidlaw Jr. Honey Bee Research Facility at UC Davis, describes the queen as an "egg-laying machine."
"She's the mother of all the bees in the hive," saysCobey, who studied at UC Davis with Harry Hyde Laidlaw Jr., (1907-2003), "the father of honey bee genetics." During the peak season, the queen can lay up to 2000 eggs a day. That amounts to about 50,000 to 80,000 workers (sterile females) and 1000 to 2000 drones (males) in the hive.
On her maiden flight, the queen bee mates with some 12 to 25 drones in mid-air and then she heads back to the hive to lay eggs for the rest of her life, says Cobey, internationally renowned for her Carniolan bees and classes on instrumental insemination and bee breeding (stock improvement).
Yes, every bee in the hive has the same mother. Not so with the fathers.
In his book, The Honey Bee Hobbyist, the Care and Keeping of Bees, Norman "Norm" Gary, UC Davis emeritus professor of apiculture, writes: "All bees in a colony develop from eggs laid by the queen, so they all share the same mother. All bees in a colony develop from eggs laid by the queen, so they all share the same mother. But as a population, they typically have around 15 fathers."
As Gary points out: "The queen bee has no control over the drones that inseminate her. (The virgin queen) mates while flying, never inside the hive."
It's a matriarchal society. The girls (worker bees) do all the work; they serve as nurse maids, nannies, royal attendants, builders, architects, foragers, dancers, honey tenders, pollen packers, propolis or "glue" specialists, air conditioning and heating technicians, guards, and undertakers. So their abbreviated life (during the summer the life span of a worker bee is only four to six weeks) is not surprising. The drones, or males, serve only a reproductive function. Once they they mate, they die.
Honey bee geneticist Robert E. Page Jr., distinguished emeritus professor of entomology at UC Davis (and emeritus provost, Arizona State University) studied with Laidlaw for his doctorate at UC Davis. He pays tribute to Laidlaw in his book, The Art of the Bee: Shaping the Environment from Landscapes to Societies.
In Chapter Nine, "The Song of the Queen," Page reprinted a poem by E. B. White (Dec. 15, The New Yorker) objecting to instrumental insemination. White opined in the poem that the queen bee should "mate with whatever drone" she encounters.
Page reprinted Laidlaw's response, published in the San Francisco Chronicle, which said in part:
Her offspring slave throughout the day,
They feed her children as best they may
They would like to see a moment
Directed toward stock improvement.
If you're interested in bees and beekeeping, or just curious about these amazing superorganisms, these books read well on Mother's Day...and any other day./span>
They're known for their creativity.
What they do, however, does not involve correcting social injustices, breaking ceilings in workplaces or pushing the latest fashions, as the descriptive adjectives might indicate.
It has everything to do with making award-winning mead or honey wine.
The event runs from 8:30 a.m. to noon each day.
"This course is for anyone who has experience making mead and wants to take their craft to the next level," says Amina Harris, director of Honey and Pollination Center, affiliated with the UC Davis Mondavi Institute and the UC Davis Department of Entomology and Nematology.
- Jeff Herbert, Superstition Meadery (Prescott, Ariz.)
- Carvin Wilson, a vocational meadmaker and mead promoter extraordinaire (Phoenix, Ariz.)
- Chrissie Manion Zaerpoor, Kookoolan Farms and Kookoolan World Meadery, and author of The Art of Mead Tasting and Food Pairing" (Yamhill, Ore.)
- Pete Bakulic, director of the Mazer Cup International Mead Competition and mead consultant
- Billy Beltz, owner of Lost Cause Meadery (San Diego.)
- Michelle and Jeremy Kyncl, owners of Hierophant Meadery (Mead, Wash.)
Yes, you read that last line right. Mead makers Michelle and Jeremy Kynci of Mead. You can sip mead in Mead at their Green Bluff Tasting Room. Mead is an unincorporated suburb north of Spokane, population under 8000, according to the 2010 Census. It was NOT named for honey wine but for Civil War Army General "Old Snapping Turtle" George Meade, 1815-1873, known for defeating Confederate General Robert E. Lee at the Battle of Gettysburg. His name lives on despite an "e" that went MIA.
Curious what Hierophant means? As the owners say on their website: "The Hierophant is generally described as 'one who reveals/shows what is sacred or holy.' We believe that the honey bee should be revered as such, as the declining population of honey bees and wild pollinators most certainly reveal to us that change is needed in the way things are done in our food system. We therefore depicted the honey bee as the Hierophant by adding a kabbalistic tree of life in our logo representation. This tree of life symbol is associated with the Hierophant."
The last day to register for the UC Davis course (the fee for the two-day course is $275) is Wednesday, May 12. Register here. You can contact Elizabeth Luu, marketing and events manager, at firstname.lastname@example.org for more information.
UC Davis is among nine universities singled out for their work in this category. The others are Cornell University, Rutgers University, Virginia Tech, Pennsylvania State University,University of Massachusetts, Louisiana State University, University of Delaware, and North Carolina State University.
Under the category, “Researchers studied chemical cues that mediate interactions among plants, pests, and predators,” UC Davis (Karban) is credited with identifying “the sagebrush cues that trigger resistance against chewing herbivores” and also finding that “plant cue effectiveness is affected by the geographic proximity of the source of the cue.”
Under the category, “Researchers used chemical ecology to protect pollinators from pesticides and disease,” UC Davis (Vannette) is credited with identifying “floral chemistry traits and microbial communities that affect the patterns or preferences of hummingbirds, honey bees, and carpenter bees.”
The Multistate Research Fund supports agricultural innovation and sustainability by providing federal funds to collaborative research projects led by State Agricultural Experiment Stations and land-grant universities. These projects bring together scientists, Extension educators, and other university, federal, and industry partners to tackle high-priority regional or national issues in agriculture, a spokesman said.
Professor Karban, an international authority on plant communication, is the author of the landmark book, Plant Sensing and Communication (University of Chicago Press).
Karban has researched plant communication in sagebrush (Artemisia tridentata) on the east side of the Sierra since 1995. His groundbreaking research on plant communication among kin, published in February 2013 in the Proceedings of the Royal Society B: Biological Sciences, drew international attention. In that study, Karban and his co-researchers found that kin have distinct advantages when it comes to plant communication, just as “the ability of many animals to recognize kin has allowed them to evolve diverse cooperative behaviors.”
“Plants responded more effectively to volatile cues from close relatives than from distant relatives in all four experiments and communication reduced levels of leaf damage experienced over the three growing seasons,” they wrote.
Karban is a fellow of Ecological Society of America and the American Association for the Advancement of Science (AAAS). Michael Pollan featured him in the Dec. 23-30, 2013 edition of The New Yorker: “The Intelligent Plant: Scientists Debate a New Way of Understanding Plants."
Vannette, an assistant professor who joined the UC Davis Department of Entomology andNematology in 2015 and a UC Davis Hellman Fellow in 2018, seeks to unlock the mysteries of flower microbes: how do plants protect against them, and can bees benefit from them?
The Vannette lab is a team of entomologists, microbiologists, chemical ecologists, and community ecologists trying to understand how microbial communities affect plants and insects (sometimes other organisms too). “We often study microbial communities in flowers, on insects or in soil,” according to her website. “We rely on natural history observations, and use techniques from chemical ecology, microbial ecology and community ecology. In some cases, we study applied problems with an immediate application including pathogen control or how to support pollinators. Other questions may not have an immediate application but are nonetheless grounded in theory and will contribute to basic knowledge and conservation (e.g. how can dispersal differences among organisms affect patterns of abundance or biodiversity?).
All plants are colonized by microorganisms that influence plant traits and interactions with other species, including insects that consume or pollinate plants, Vannette explains. “I am interested in the basic and applied aspects of microbial contributions to the interaction between plants and insects. I also use these systems to answer basic ecological questions, such as what mechanisms influence plant biodiversity and trait evolution.”
“Much of the work in my lab focuses on how microorganisms affect plant defense against herbivores and plant attraction to pollinators. For example, we are interested in understanding the microbial drivers of soil health, which can influence plant attractiveness to herbivores and the plant's ability to tolerate or defend against damage by herbivores. In addition, we are working to examine how microorganisms modify flower attractiveness to pollinators. This may have relevance in agricultural systems to improve plant and pollinator health.”
Vannette, a former postdoctoral fellow at Stanford University's biology department, holds a doctorate in ecology and evolutionary biology (2011) from the University of Michigan. Her recent research grants include two from the National Science Federation (NSF). One is a five-year Faculty Early Career Development (CAREER) Program award, titled “Nectar Chemistry and Ecological and Evolutionary Tradeoffs in Plant Adaptation to Microbes and Pollinators.” The other is a three-year collaborative grant, “The Brood Cell Microbiome of Solitary Bees: Origin, Diversity, Function, and Vulnerability.”
"Mr. GARAMENDI. Madam Speaker, I rise today to honor Bruce Hammock and his exemplary interdisciplinary career. He has been a legendary figure in his field for over four decades and his efforts have made critical advancements in our understanding of neurodegenerative diseases, non- addictive solutions to managing chronic pain, and environmental conservation.
"Dr. Hammock's recent research on regulatory enzyme inhibitors and their effect on neuroinflammation has reshaped the way we understand both the cause and cure of the degenerative disease. Alongside his UC Davis team, Dr. Hammock partnered with Baylor University as well as other researchers across the globe to study soluble epoxide hydrolase (sEH) and its effect on the brains of mice. Dr. Hammock's study found that inhibiting sEH may offer a new pathway to reduce neuroinflammation and neurodegeneration; leading to a breakthrough in recognizing the potential benefits of sEH inhibitors in Alzheimer's treatment.
"Groundbreaking research is nothing new in the world of Dr. Hammock. He is currently a distinguished professor at UC Davis in the Department of Entomology and Nematology and part of the UC Davis Comprehensive Cancer Center. During his time at the university Hammock has been at the helm of the Superfund Research Program for over three decades--a government-funded program focused on finding solutions to the complex health and environmental issues linked with the nation's hazardous waste sites.
"In addition to his invaluable contributions to science, Dr. Hammock has taken up another admirable charge--to make science and learning fun. Every year he and his lab organize a water balloon fight between faculty and students on the lawn of UC Davis' Briggs Hall where other labs and bystanders join in on the action. This event is a small glimpse into Hammock's unique character--one described by colleagues as enthusiastic, creative, and hard-working. Dr. Hammock's limitless drive and curiosity contribute both to the stellar reputation of UC Davis as an esteemed research institute and California's 3rd Congressional District as a whole. We wish him all the best in his endeavors and look forward to seeing all that he accomplishes in the future."
Hammock, who holds a joint appointment with the UC Davis Department of Entomology and Nematology and the UC Davis Comprehensive Cancer Center, joined the UC Davis faculty in 1980. He is the founding director (1987-present) of the UC Davis NIEHS (National Institute of Environmental Health Sciences) Superfund Research Program and is a founding member (1990-present) of the UC Davis Comprehensive Cancer Center.
Hammock co-discovered a human enzyme termed Soluble Epoxide Hydrolase (sEH), a key regulatory enzyme involved in the metabolism of fatty acids. It regulates a new class of natural chemical mediators, which in turn regulates inflammation, blood pressure and pain. Hammock and his lab have been involved in enzyme research for more than 50 years.
Hammock is the founder and chief executive officer of the Davis-based pharmaceutical company, EicOsis LLC, formed in 2011 to develop an orally active non-addictive drug for inflammatory and neuropathic pain for humans, as well as a version in development for treating painful conditions in companion animals. A drug candidate known as EC5026 and now in human trials, targets a novel pathway to block the underlying cause of certain types of pain
Highly honored by his peers, Hammock is a fellow of the National Academy of Inventors, which honors academic invention and encourages translations of inventions to benefit society. He is a member of the U.S. National Academy of Sciences, a fellow of the Entomological Society of America, and the recipient of the Bernard B. Brodie Award in Drug Metabolism, sponsored by the America Society for Pharmacology and Experimental Therapeutics. He is the first McGiff Memorial Awardee in Lipid Biochemistry. The Eicosanoid Research Foundation recently honored him for work on oxidized lipids.
Hammock and his laboratory are now deeply involved in COVID-19 research. The National Institute of Environmental Health Sciences today posted their work: "Biomarker Suggests Severity of COVD-19 Respiratory Distress."
"In a study funded in part by NIEHS, researchers reported April 1 that certain fatty acids in the blood of COVID-19 patients may predict the severity of adult respiratory distress syndrome (ARDS)," the article began. "The fatty acids may also offer a target for treatment. ARDS, characterized by fluid buildup in the lungs, is the second leading cause of death in COVID-19 patients, according to the National Center for Biotechnology Information.
"Bruce Hammock, Ph.D., longtime NIEHS grantee and director of the NIEHS-funded University of California, Davis (UC Davis) Superfund Research Program (SRP) Center, led the study. His team examined six COVID-19 patients over five days and found that those with severe lung involvement showed higher levels of certain fatty acids compared with healthy control subjects. These fatty acids, called leukotoxins and leukotoxin diols, are known to play a role in inflammatory disease and ARDS, but this is the first study of their role in respiratory complications related to COVID-19."
Water Balloon Battles
Insisting that science should be fun, Hammock launched the Bruce Hammock Lab Water Balloon Battles nearly 20 years ago on the Briggs Hall lawn (outside his office) as a way to develop camaraderie in his lab; to take a 15-minute break; and to beat the triple-digit heat. The battle, usually waged on a sweltering July afternoon, is basically "15 Minutes of Aim" because that's how long it takes for the 30-some water warriors to toss 2000 water balloons at one another. Stray buckets of water are fair game, too.
Water balloon battle coordinator Christopher Morisseau, who holds the title of "professional researcher" in the Hammock lab, says the annual event is open to "all who want to get wet," which includes students and faculty of other UC Davis labs, spouses, children, and passersby. One year a police officer joined in.
The COVID-19 pandemic canceled the 2020 water battle. And COVID, coupled with the renovation of Briggs Hall and the grounds, may cancel this year's clash as well. (See images of the 16th annual event, a super-soaker that took place July 12, 2019.)
The tribute to Bruce Hammock in the Congressional Record is well deserved. And it's also good to see the Bruce Hammock Lab Water Balloon Battle mentioned. How many times have you seen a UC Davis water balloon battle entered in the Congressional Record?
It's one of the highest honors a scientist can receive. Members are elected to NAS in recognition of their distinguished and continuing achievements in original research.
Agrawal received his doctorate in population biology in 1999 from UC Davis, working with major professor Richard "Rick" Karban, UC Davis Department of Entomology and Nematology.
"Anurag is an inspiration as a scientist and as a person," Karban said. "I've learned a lot from him."
At Cornell, Agrawal is the James A. Perkins Professor of Environmental Studies in the College of Agriculture and Life Sciences. He researches the ecology and evolution of interactions between wild plants and their insect pests, including aspects of community interactions, chemical ecology, coevolution and the life cycle of the monarch butterfly.
Agrawal is the author of the celebrated book, Monarchs and Milkweed: A Migrating Butterfly, a Poisonous Plant, and Their Remarkable Story of Coevolution, published in 2017 by Princeton University Press. The book won a 2017 National Outdoor Book Award in Nature and Environment and an award of excellence in gardening and gardens from the Council of Botanical and Horticultural Libraries. It was also named one of Forbes.com's 10 best biology books of 2017. Read a review of his Monarchs and Milkweed book from the journal Ecology and read the first chapter here. (You can order the book here.)
As Agrawal said in a Cornell news release, “It's a tremendous honor and totally unexpected. I look forward to representing Cornell and also playing a part in the NAS role of advising the U.S. government on science policy.”
"A key research focus for Agrawal's Phytophagy Lab is the generally antagonistic interactions between plants and insect herbivores," according to the Cornell news release. In an attempt to understand the complexity of communitywide interactions, questions include: What ecological factors allow the coexistence of similar species? And what evolutionary factors led to the diversification of species? Agrawal's group is currently focused on three major projects: the community and evolutionary ecology of plant-herbivore relationships; factors that make non-native plants successful invaders; and novel opportunities for pest management of potatoes. Recent work on toxin sequestration in monarch butterflies was featured on the cover of the April 20 issue of Proceedings of the National Academy of Sciences."
Agrawal holds two degrees from the University of Pennsylvania, a bachelor's degree in biology and a master's degree in conservation biology. He joined the Cornell faculty in 2004 as an assistant professor of ecology and evolutionary biology, with a joint appointment in the Department of Entomology. He advanced to associate professor in 2005, and to full professor in 2010. He was named the James A. Perkins Professor of Environmental Studies in 2017.
A fellow of the American Association for the Advancement of Science (2012), and recipient of the American Society of Naturalist's E.O. Wilson Award in 2019, Agrawal won the Entomological Society of America's 2013 Founders' Memorial Award and delivered the lecture on Dame Miriam Rothschild (1908-2005) at ESA's 61st annual meeting, held in Austin, Texas.
Agrawal was at UC Davis in January of 2012 to present a seminar on "Evolutionary Ecology of Plant Defenses." His abstract: "In order to address coevolutionary interactions between milkweeds and their root feeding four-eyed beetles, I will present data on reciprocity, fitness tradeoffs, specialization and the genetics of adaptation. In addition to wonderful natural history, this work sheds light on long-standing theory about how antagonistic interactions proceed in ecological and evolutionary time."
