The National Science Foundation (NSF) has awarded a three-year collaborative research grant to five faculty members at Baker University, Baldwin City, Kansas, and to Lynn Kimsey, director of the Bohart Museum and professor, UC Davis Department of Entomology and Nematology.
All the tardigrades collected by Baker University's faculty and students will find a new home at the Bohart.
“Our part in all this is to act as a repository for all of the specimens collected,” Kimsey said. “We have one of the four largest collections of tardigrades in the world.”
The NSF awarded $256,849 for the project, titled “Cross Departmental Development of an Automated Species Identification System for the Phylum Tardigrada Found on Birds.” Collaborating with Kimsey are Baker University faculty members Scott Kimball, associate professor of biology; Randy Miller, director of research; Robert Schukei, assistant professor of computer science; Mahmoud Al-Kofahi, professor of physics; and Irene Unger, associate professor of biology and director of the Baker Wetlands.
"We thought we had a great project and were thrilled the award committee agreed to fund the full scope of our project," Kimball said in a press release. “Our group will engineer an automated process of preparing microscope slides of tardigrade specimens collected from any of several sources. The second objective is to design a species identification software application that will use computer learning processes to create efficiencies in the identification of specimens. All of this will be used to answer biological questions related to the geographic dispersion of tardigrades, specifically as it relates to the relationship between tardigrades and the birds in their environments that may serve to disperse them across the landscape."
The Bohart Museum's tardigrade current collection includes some 25,000 slide-mounted specimens. In a recent newsletter, Kimsey described the water bear as “one of the most peculiar and indestructible groups of animals known. The microscopic and nearly indestructible tardigrade can survive being heated to 304 degrees Fahrenheit or being chilled for days at -328 F. And, even if it's frozen for 30 years, it can still reproduce." See video on EurekAlert.
They belong to their own phyllum, the Tardigrada (meaning "slow steppers"), and to date there are some 1,500 described species throughout the world. "Tardigrades can survive high pressures of more than 1,200 atmospheres found in the bottom of the abyss," Kimsey says. "They can tolerate 1,000 times more ionizing radiation than other animals."
In appearance, the pudgy water bear seems as cuddly as a teddy bear. It has a barrel-shaped body and eight pudgy legs. The adults usually range from 0.3 to 0.5 mm in length. German zoologist Johann August Ephraim Goeze (1731-1793) first described the critters in 1773, referring to them as "kleiner Wasserbär," or "little water bears."
They're easiest to find on lichens and mosses, Kimsey says, but they can also be found on beaches, in the subtidal zone, freshwater sediments, soil, hot springs and even on barnacles. They've been found "high in the Himalayas to down in the deep sea and even in the interior of Antarctica,” Kimsey said.
They mostly feed on plants or bacteria "but some are predators on smaller tardigrades," Kimsey related. “They use the stylets in their tubular mouth (snout) to pierce "individual plant or bacterial ells or small invertebrates."
Why is the water bear so indestructible? In research published in 2016, geneticist Takekazu Kunieda and his colleagues from the University of Tokyo found that the water bear expresses a tardigrade-specific protein that binds itself to DNA. This acts like a "shield against x-ray radiation, preventing the DNA from snapping apart," according to an article published in Gizmodo.
Said Kimsey: "Tardigrades are awesome. They can dry out completely and then become immortal. In fact, SpaceIL may have left thousands of dried tardigrades on the moon when it crashed (in 2019)." (See news story.)
Plans call for a tardigrade sculpture to grace the entrance to the Bohart Museum, located in Room 1124 of the Academic Surge Building on Crocker Lane. The artistic concrete sculpture will be about 4 feet by eight feet, about the size of a cow. A GoFundMe account, set up by the Bohart Museum Society, seeks $5000, and is at https://www.gofundme.com/f/waterbear-sculpture
"Tardigrades are really popular with kids in part because of their representation in the movies Ant-Man and Ant-Man and the Wasp, Star Trek and Family Guy," Kimsey noted.

And rightfully so. It's a stand against racism and a step toward a more diverse and inclusive organization.
And frankly, it's a more appropriate name.
ESA, founded in 1889, launched the games in 1982, naming them for Swedish scientist-physician Carl Linnaeus (1707-1778), the father of taxonomy. He was a botanist and zoologist as well as a physician.
ESA describes The Games as a "fast-paced, college-bowl style contest in which students from various colleges and universities test their knowledge by answering questions on insect science. Students compete first at the regional branch level, and then the winning teams compete each year at the national level at ESA's Annual Meeting."
A petition on Research Gate drew some 1500 approvals for the name change. However, many members began seeking a name change several years ago.
Here's why: Linnaeus' classifications of the human race.
Linnaeus made "offensive, race-based classifications of humans that helped form a basis for racism in science," according to a Request for Change on Research Gate. "The recent police murders of George Floyd, Breonna Taylor, Ahmaud Arbery, Tony McDade, and too many other Black Americans have put a national spotlight on racial injustice in our country. White supremacy and racism have existed in academic and scientific institutions since their advent, but these events have catalyzed heightened reflection and action around justice within academia."
Other points involving the name switch from Linnaean Games to Entomology Games:
- Linnaeus was not an entomologist
- The trivia questions deal mostly with insect science and entomologists, not taxonomy.
- Most people outside the world of entomology probably cannot relate to the meaning of the Linnaean Games, but they can to "Entomology Games"
As ESA president Alvin Simmons, a research entomologist at USDA-ARS, U.S. Vegetable Laboratory, Charleston, S.C., said in the ESA news release: “National events this year have brought issues of diversity and inclusion within our discipline and our Society to the forefront. Ultimately, the board believed that the loss of any student competitors who felt unwelcome because of the name of the Games went against ESA's commitment to diversity, inclusion, and students as the future of entomology. A name can be replaced, but each entomologist brings a unique and valuable contribution to our Society that is irreplaceable. The Entomology Games will continue ESA's traditions of fun, competition, and school pride.”
ESA published a statement on Why Black Lives Matter to Entomology on June 1, which said in part: "Historically, people of color have been less likely to choose careers in the life sciences, and even today black entomologists make up 2.7 percent of the ESA membership, up from 2 percent in 2012. Every time a person is kept from contributing to our understanding of entomology due to systemic inequities, our entire discipline is impoverished."
Meanwhile, due to the coronavirus pandemic, ESA will conduct its 2020 ESA meeting in a virtual format. From its website: "We are excited to embrace the virtual format and build an exceptional meeting that will truly embody the spirit of Entomology for All—a meeting where all insect scientists can participate and share their work, regardless of location, specialty area, or ability to travel. Entomology 2020 will feature multiple live-streams running simultaneously November 16-19. On-demand content will be available from November 11-25."
University of California teams have done well in the The Games. A UC Davis team won the national championship in 2015, and a UC Berkeley-UC Davis team won two national championships, one in 2016 and one in 2018. The 2016 Games were deemed international as it occurred during a joint meeting of ESA and the International Congress of Entomology (ICE) in Orlando, Fla. (Walter Leal, UC Davis distinguished professor and USDA-ARS research entomologist Alvin Simmons co-chaired the ICE meeting.)
The 2019 UC team made it to the finals but didn't place. It was captained by Ralph Washington Jr., a UC Berkeley public policy graduate student who received his bachelor's degree in entomology at UC Davis. He was joined by three UC Davis Department of Entomology and Nematology doctoral students: Brendon Boudinot, Zachary Griebenow and Jill Oberski, all of the Phil Ward lab, and alternates Miles Dakin of the Christian Nansen lab and Hanna Kahl of the Jay Rosenheim lab.
Washington captained all four recent teams, and Boudinot helped anchor all of them.
Statistics include:
- 2018: UC won the national championship (this links to a UC Davis news story) in Vancouver, B.C., defeating Texas A&M Graduates, with Washington captaining the team and joined by UC Davis graduate students Boudinot, Oberski and Griebenow of the Phil Ward lab, and Emily Bick of the Christian Nansen lab.

- 2017: The UC team did not compete. (Texas A&M won the national championship; see championship round on YouTube)
- 2016: UC won the national and international championships at the joint meeting of ESA and ICE in Orlanda, Fla., defeating the University of Georgia. (See championship round on YouTube)
- 2015: UC won the national championship at the games held in Minneapolis, Minn., defeating the University of Florida. (See championship round on YouTube)

The Bohart Museum will live-stream the free open house on Facebook. Entomologist Jeff Smith, who curates the 500,000 Lepidoptera (butterflies and moths) collection, will show specimens and answer questions.
"We started holding a moth-themed open house near Mother's Day in May, because people who are enthusiasts for moths are called moth-ers,” said Tabatha Yang, education and outreach coordinator for the Bohart Museum. “We then switched our programming to align with National Moth Week. This year's Moth Week is July 18-26. The annual event is celebrated throughout the world with private and public events.
Bohart Museum officials are preparing videos on black-lighting and how to spread and pin moths.
During the Facebook Live program, viewers can type in their questions on moths.
Smith is expected to answer questions such as:
- What is the largest moth?
- How do butterflies and moths differ?
- What is so unique about moths?
- Why should we be concerned with moth diversity?
Kimsey, who has directed the museum since 1989, remembers when Smith joined the museum. “When Jeff was working for Univar Environmental Services, a 35-year career until his retirement in 2013, he would spend some of his vacation days at the museum. Over the years Jeff took over more and more of the curation of the butterfly and moth collection. He took home literally thousands of field pinned specimens and spread their wings at home, bringing them back to the museum perfectly mounted. To date he has spread the wings on more than 200,000 butterflies and moths. This translates into something like 33,000 hours of work!” The numbers have since increased.
“About a decade ago, Jeff began helping us by assembling specimen drawers from kits that we purchased,” Kimsey related. “This substantially lowered our curatorial costs, from $50/drawer to $16/drawer. We use several hundred drawers a year to accommodate donated specimens, research vouchers and specimens resulting from research grants and inventories. More recently, he's been accumulating scrap lumber and making the drawers from scratch at no cost to us. Overall, he has made more than 2000 drawers. Additionally, he makes smaller specimen boxes with the leftover scrap wood, which are used by students taking various field courses in the department. We simply could not curate the collection without his contributions.”
Kimsey praised Smith for completely reorganizing the butterfly and moth collection. “It's no small feat to rearrange this many specimens, housed in roughly one thousand drawers,” she said. “Many thousands of the specimens needed to be identified, and the taxonomy required extensive updating and reorganization.”
The Bohart Museum, located in Room 1124 of the Academic Surge Building on Crocker Lane, UC Davis campus, houses a global collection of nearly eight million specimens. It is also the home of the seventh largest insect collection in North America, and the California Insect Survey, a storehouse of the insect biodiversity. Noted entomologist Richard M. Bohart (1913-2007) founded the museum.
The Bohart Museum is the home of a “live” petting zoo featuring Madagascar hissing cockroaches, walking sticks and tarantulas, and a gift shop stocked with T-shirts, sweatshirts, books, jewelry, posters, insect-collecting equipment and insect-themed candy.

The honey bees love it.
So do the long-horned bees, bumble bees, carpenter bees, European paper wasps, syrphid flies, butterflies, blister beetles, spotted cucumber beetles, crab spiders, praying mantids, and assorted other insects.
The Mexican sunflower (Tithonia rotundifolia) blooming in gardens around California and beyond is a delight to see.
A native of Mexico and Central America and an annual, it's a member of the sunflower family Asteraceae. In our yard in Vacaville, Calif, it blooms from May or early June through October and November--just in time for the migrating monarchs that pass through on their way to their overwintering sites along coastal California.
But for now, it belongs to the honey bees and the long-horned bees, such as Melissodes agilis.
We encountered this lone honey bee last week--a single bee in need of nectar but not in need of a dive-bombing by the male territorial Melissodes agilis.
The last image, of her in an upside-down stance and peering through the petals, indicates this bee is not about to let her guard down.
Not now.
Want to learn about honey bees? Be sure to read Norman Gary's book, The Honey Bee Hobbyist: The Care and Keeping of Bees. Gary, a UC Davis emeritus professor of entomology, has kept bees for more than seven decades and has held or holds the titles of teacher, scientist, researcher, author, bee wrangler and musician. Check out his website.
Also read the UC book, California Bees and Blooms: A Guide for Gardeners and Naturalists, by Gordon Frankie of UC Berkeley, (the late) Robbin Thorp of UC Davis, and Rollin Coville and Barbara Ertter, both affiliated with UC Berkeley.

We call it the Fourth of July or Independence Day.
Our 13 American colonies rose up against the monarch of Great Britain, King George III, and declared themselves free and independent.
This weekend, no thanks to the coronavirus pandemic, we won't celebrate with fireworks, parades, picnics, family reunions or baseball games, but we will give thanks to the 13 colonies who gave us our freedom from a troubling monarch.
Today we watched a different kind of monarch, a monarch butterfly, Danaus plexippus, gain her freedom as she eclossed from her chrysalis.
From an egg to a caterpillar to a chrysalis to an adult..."Welcome to the world, Ms. Monarch."
But first, let Ms. Monarch cling to the Hot Lips salvia, Salvia microphylla, and dry those wings. Let her watch the honey bees, carpenter bees, cabbage white butterflies, Gulf Fritillaries, damselflies, and syrphid flies forage. Let her react when they buzz, bounce or bump into her. Beware of that praying mantis!
She will know when she's had enough...just like the 13 colonies knew when enough was enough and King George III lost his American colonies.
