Learn All About Nematodes at the UC Davis Biodiversity Museum Day

Ever seen tomato roots infected with root-knot nematodes?

Ever seen nematode specimens in organs of a whale?

You’ll see that—and more—at the nematode (aka roundworm) display at the 13th annual UC Davis Biodiversity Museum Day on Saturday, Feb. 10. The free and family friendly event, known as “Super Science Day," will showcase 10 museums or collections.

One of them is the nematode collection, which last year drew thousands of attendees. Visitors commented “Fantastic display!” and “I learned a lot!” Many  were gardeners with questions about root-knot nematodes. Many were dog lovers concerned about heartworm. The heartworm culprit? It’s a parasitic roundworm, Dirofilaria immitis, commonly known as “heartworm” or “dog heartworm.”

The nematode collection, headed by Shahid Siddique, associate professor, Department of Entomology and Nematology, will be open from 10 a.m. to 2 p.m.. in the Katherine Esau Science Hall, across from Briggs Hall.

“Our collection will highlight both animal and plant parasitic nematodes,” said graduate student Alison Blundell of the Siddique lab. “We will have mostly all preserved specimens from our nematode collection for the community to look at, and some live free-living (good nematodes) under the microscope for viewing. We hope to inspire people to understand what a nematode is and how they can impact their own lives!”

“We will have preserved specimens of common crops and plants you see in your garden infected with nematodes,” she added. “We also plan to have live C. elegans (Caenorhabditis elegans) to watch how they move through the environment. Come talk to experts in the field and see why worms are cool and you will receive a cool magic worm to take home as well!”

Last year's Biodiversity Museum Day drew some 4000 people, said chair Tabatha Yang, education and outreach coordinator for the Bohart of Museum of Entomology who co-founded the event.

"Traditionally UC Davis Biodiversity Museum Day is a free, educational event for the community where visitors get to connect with UC Davis scientists from undergraduate students to staff to emeritus professors," Yang posted on the website. "In 2021, we pivoted to a month-long, virtual program. In 2022, also because of COVID regulations, we held the event in the UC Davis Conference Center as an 'expo.' In 2023 and again this year in 2024 we continued to maintain that spirit and were excited to have the event in our near our home departments."
