The event, to be held Saturday, Feb. 15, is a science-based day at which visitors of all ages can meet and talk with UC Davis scientists—from undergraduates to staff to emeriti professors—“and see amazing objects and organisms from the world around us,” said volunteer chair Tabatha Yang, who is also the education and outreach coordinator for the Bohart Museum of Entomology.
The 2019 event drew more than 4,000 visitors. It's always held the Saturday of Presidents' Weekend. Displays range from ancient dinosaur bones to stick insects; from hawks to honey bees; and from California condor specimens to carnivorous plants.
Sponsors (two openings available) who pledge by Jan. 6 to donate $3000 will receive “Presenting Sponsor” recognition (donor name or company logo) on the T-shirts, as well as recognition on social media fliers, fliers, banners and other entities.
Other contributors are “Biodiversity Allies” or $1500 donors (four openings available); “Biodiversity Supporters” or $500 donors, and “Biodiversity Friends” or $100 donors. General supporters, who can give what they can throughout the year, are also needed. More information on how to give is on the UC Davis Biodiversity Museum website. All donations are tax-deductible and much appreciated, the organizers said.
Open to the public on Feb. 15 will be:
- Arboretum and Public Garden
- Bohart Museum of Entomology
- Botanical Conservatory

The 13 museums or collections represent nine departments, all within walking distance on campus except the Raptor Center on Old Davis Road and the bee garden on Bee Biology Road. The UC Davis Department of Entomology and Nematology will showcase three museums or collections: Bohart Museum of Entomology, Haagen-Dazs Honey Bee Haven, and the Nematode Collection.
Founded in 2011, UC Davis Biodiversity Museum Day is billed as an annual event for the public to learn about nature, science and the work of UC Davis around the globe. The science-based day focuses on natural history showcasing the university's critically important, research and teaching collections, the committee related. Many students attend Biodiversity Museum Day to gather information on career choices.
All participating museums and collections have active education and outreach programs, but the collections are not always accessible to the public. In the event of rain, alternative locations are planned for the outdoor sites.

“Each year, entrepreneurially minded PhD or postdoctoral students are invited to join venture capital partners onsite to gain first-hand experience on what it takes to have a successful startup, then apply that knowledge to develop and de-risk their own potential technology, product or process at UC Davis,” according to an IIFH news release.
Abrieux, whose project is titled “Improving Integrated Pest Management (IPM) Practices with Biotechnology,” is working with The Production Board (TPB), a San Francisco-based technology incubator and investment holding company that aims to improve the efficiency and economics of global food and agriculture markets.
Recipient Tawny Scanlan, a UC Davis doctoral candidate in animal biology, is researching “Enhancing Production Efficiency and Sustainability in Aquaculture” and working with Food for Thought Worldwide Ventures (FTW), a San Francisco-based early-stage venture fund investing in breakthrough hardware, software and biotech solutions in the worldwide food system.
Abrieux is utilizing his expertise in insect physiology, behavioral analysis and molecular biology to tackle problems related to agriculture and enhance food security. He seeks to develop innovative approaches in biotechnology to improve IPM practices by translating basic research into applied solution and ensure crop production sustainability.
Abrieux received his doctorate in biology from Angers University, western France, where investigated the role of hormones and biogenic amines in the behavioral response to the sex pheromone in the noctuid Agrotis ipsilon. He joined the Chiu lab in the spring of 2016 as a postdoctoral fellow.
In the Chiu lab, he explores the interactions between the clock and endocrine system underlying seasonal adaptation in the pest, the spotted-wing drosophila, Drosophila suzukii. “I am particularly interested in developing integrative approaches to better understand how physiological state and behavior could be modulate at both transcriptional and translational levels and facilitate insect adaptability to changing environments.” (He presented a UC Davis Department of Entomology and Nematology seminar on "Understanding the Molecular Mechanisms Underlying Photoperiodic Time Measurement in Drosophila melanogaster" in February 2018.)
"I am convinced that biotechnologies can have an important and beneficial impact on society,” Abrieux says, “and the likelihood to facilitate progress is considerably increased through collaborative efforts between actors from diverse domains of expertise.”
His supervisor, associate professor Joanna Chiu, vice chair of the UC Davis Department of Entomology and Nematology, commented: “The Production Board Fellowship represents a perfect opportunity for Antoine to advance his understanding of the food security market and current needs, and to develop entrepreneurship ideas that he can take with him to the next stage of his career."
Abrieux, fascinated with insects since his childhood, maintains a photography website, including macro images of insects at https://antoineabrieux.wixsite.com/antoine-abrieux/portfolio.

The Bohart Museum of Entomology is showcasing the innovative research of UC Davis evolutionary ecologist Leslie Saul-Gershenz, who studies how blister beetle nest parasites mimic the sex pheromone of digger bees.
Bohart associate Emma Cluff created the wall display, “Digger Bees and Their Nest Parasites,” which examines the life cycle, research process, results, research challenges and implications.
The display runs through May 16. The Bohart Museum is located in Room 1124 of the Academic Surge Building on Crocker Lane, UC Davis campus. It is open to the public, Monday through Thursday, from 9 a.m. to noon and from 1 to 5 p.m., except on holidays.
Gershenz, associate director of research, Wild Energy Initiative, at the John Muir Institute of the Environment, UC Davis, researches the chemical ecology and parasite-host interactions of these solitary native bees and their nest parasites across the western U. S., including the coastal sand dunes of Oregon and the Mojave Desert in south-central California.
Gershenz, who holds a doctorate in entomology from UC Davis, did much of her work at the Mojave National Preserve, where she tracked the solitary bee Habropoda pallida and its nest parasite, a blister beetle, Meloe franciscanus.
The larvae of the parasitic blister beetle produce a chemical signal or allomone, similar to that of a female bee's pheromone, to lure males to the larval aggregation. The larvae attach to the male bee on contact and then transfer to the female during mating. The end result: the larvae wind up in the nest of a female bee, where they eat the nest provisions and likely the host egg.
Saul-Gershenz' experiments found the allomones “released by each population of M. franciscanus triungulin (larvae) mimic the pheromones released by a specific species of Habropoda bees native to their local habitat,” Cluff wrote in the display. “Leslie found that these differences had a genetic basis. She also found that local bee species were more attracted to the allomones released by their local triungulin population.”
“The M. franciscanus triungulin hatching is synchronized with the emergence of adult female Habropoda bees,” the display reads. “The triungulins aggregate on plant stems and release an allomone blend which attracts male bees. The aggregation of triungulins hop on to male bees who have chosen to investigate the allomone. Once the male bees find a real female bee, they mate in a ‘mating ball' at which time the triungulins transfer to the female. All this effort is so that the triungulins can get a free ride to the nest that the female bee lays her eggs in. Once inside the nest burrow, the triungulins will feed on the net provisions and likely the egg itself and will remain there until they emerge as adults the following winter.”
Results? “Leslie's experiments found that the allomones released by each population of M. franciscanus triungulin mimic the pheromones released by a the specific species of Habropoda bees native to their local habitat,” Cluff wrote. “Leslie found that these differences had a genetic basis. She also found that local bee species were more attracted to the allomones released by their local triungulin population.”
The research contributes to the understanding of the communication signals of bees in the genus Habropoda. Saul-Gershenz is currently finishing two research papers: the basic biology of digger bee Habropoda pallida, and the biology of the silver digger bee Habropoda miserabilis.
She and her husband, Norman, are the co-founders of the Bay Area-based SaveNature.Org. The international conservation consortium works with partners to protect ecosystems around the world.
Collect the first cabbage white butterfly of the year in the three-county area of Sacramento, Solano and Yolo and win a pitcher of beer or its equivalent, compliments of Art Shapiro, UC Davis distinguished professor of evolution and ecology.
Shapiro is sponsoring his 48th annual Beer-for-a-Butterfly Contest and it's all in the name of research to determine the first flight of the cabbage white butterfly, Pieris rapae. Since 1972, when he launched the contest, the first flight has varied from Jan. 1 to Feb. 22, averaging about Jan. 20.
The butterfly inhabits vacant lots, fields and gardens where its host plants, weedy mustards, grow. The male is white. The female is often slightly buffy; the "underside of the hindwing and apex of the forewing may be distinctly yellow and normally have a gray cast,” Shapiro said. “The black dots and apical spot on the upperside tend to be faint or even to disappear really early in the season.”
The contest rules include:
- It must be an adult (no caterpillars or pupae) and be captured outdoors.
- It must be delivered alive to the department office, 2320 Storer Hall, UC Davis, during work hours, 8 a.m. to 5 p.m., Monday through Friday, with the full data (exact time, date and location of the capture) and your name, address, phone number and/or e-mail. The receptionist will certify that it is alive and refrigerate it. (If you collect it on a weekend or holiday, keep it in a refrigerator; do not freeze. A few days in the fridge will not harm it, Shapiro says.)
- Shapiro is the sole judge.
Shapiro, who maintains a research website at http://butterfly.ucdavis.edu, usually wins his own contest and did so again in 2019. He collected the winner near the Suisun Yacht Club, Suisun City, Solano County, at 1:12 p.m., Friday, Jan. 25.
Shapiro has been defeated only four times, and all by UC Davis graduate students. Jacob Montgomery defeated him in 2016, and his graduate student, Adam Porter, won in 1983. His graduate students Sherri Graves and Rick VanBuskirk defeated him in the late 1990s.
The list of winners, dates and locations since 2010:
- 2019: Jan. 25: Art Shapiro collected the winner near the Suisun Yacht Club, Solano County
- 2018: Jan. 19: Art Shapiro collected the winner in West Sacramento, Yolo County
- 2017: Jan. 19: Art Shapiro collected the winner on the UC Davis campus
- 2016: Jan. 16: Jacob Montgomery, UC Davis graduate student, collected the winner in west Davis
- 2015: Jan. 26: Shapiro collected the winner in West Sacramento
- 2014: Jan. 14: Shapiro collected the winner in West Sacramento
- 2013: Jan. 21: Shapiro collected the winner in West Sacramento
- 2012: Jan. 8: Shapiro collected the winner in West Sacramento
- 2011: Jan. 31: Shapiro collected the winner in Suisun, Solano County
- 2010: Jan. 27: Shapiro collected the winner in West Sacramento
The 2019 winner was the earliest recorded in Suisun City in 47 seasons, said Shapiro. His notes from Jan. 25 read: “Very little in bloom: many dandelions, one Eucalyptus, three Hirschfeldia (mustard), two Raphanus (radish), many Malva (mallow) and a few Picris (sunflower family). Site still 30 percent flooded. I went to all the usual Vanessa (butterfly) places and found nothing. I searched more than 100 Malva plants for larvae and found nothing. But near the Suisun Yacht Club (703 Civic Center Blvd., Suisun City) at 1:12 p.m. I saw a rapae. It didn't land and I had to take it in the air. It's a small and very heavily infuscated male.” It had just eclosed that day, he said.
The UC Davis professor has monitored butterfly population trends on a transect across central California since 1972 and records the information on his research website. His 10 sites stretch from the Sacramento River Delta through the Sacramento Valley and Sierra Nevada mountains to the high desert of the Western Great Basin. He visits his sites every two weeks "to record what's out" from spring to fall, weather permitting. He has studied more than 160 species of butterflies in his transect. The largest and oldest database in North America, it was recently cited by British conservation biologist Chris Thomas in a worldwide study of insect biomass.
Shapiro and illustrator Timothy D. Manolis co-authored A Field Guide to Butterflies of the San Francisco Bay and Sacramento Valley Regions, published in 2007 by the University of California Press. Shapiro is a Fellow of the American Association for the Advancement of Science, the Royal Entomological Society, and the California Academy of Sciences.

The book, Biodemography: An Introduction to Concepts and Methods, is the work of Carey and Deborah Roach, a University of Virginia biology professor and a past president of the Evolutionary Demographic Society. The landmark book will be published Jan. 7 by Princeton University Press.
Carey, one of the founding fathers of the interdisciplinary field and considered the global authority on arthropod demography, describes the field of biodemography as linking a number of professions. “It is an essential resource for demographers, epidemiologists, gerontologists, and health professionals as well as ecologists, population biologists, entomologists, and conservation biologists.”
“The authors aim to enlighten and inspire and they succeed,” Vaupel wrote. He cited the important and innovative ideas, mode of explanation, and the graphic illustrations, all of which make the book “sparkle.”
Carey and Roach cover everything from baseline demographic concepts to biodemographic applications, and “present models and equations in discrete rather than continuous form to enhance mathematical accessibility,” according to Princeton University. (Watch Carey's book trailer on YouTube)
Topics range from kinship theory and family demography to reliability engineering and tort law, and also demographic disasters such as the Titanic and the destruction of Napoleon's Grande Armée. It also includes an analysis about the Donner Party.
The authors point out the differences in survival, “such that the young and old died at higher rates than the middle-aged. Indeed with one exception, no individuals of ether sex beyond 49 years survived. Males not only died at roughly twice the overall rate as females, but many males also died earlier in the disaster period. Third, kinship size and association were important to survival; individuals not associated with a kinship group died at much higher rates than those who were associated with a group.”
Carey, who holds a doctorate in entomology from UC Berkeley and studied population biology for a year at Harvard while working on his doctorate, joined the UC Davis Department of Entomology in 1980. He served as the principal investigator of a 10-year, $10 million federal grant on “Aging in the Wild,” encompassing 14 scientists at 11 universities.
Highly honored for his research, teaching and public service, Carey is a fellow of four organizations; American Association for the Advancement of Science, Entomological Society of America, California Academy of Science and the Gerontological Society of America.
