We focus on understanding the mechanisms by which species interactions maintain species diversity, and how we can harness these processes to manage and restore diversity in human-modified systems. We focus on pollinators because they are critical for pollination in managed and natural plant communities, but our research is broadly applicable across ecological interactions. Our aim to discover new insights into how communities form, evolve, and persist through time and space, aiding in the prediction and prevention of community collapse. We combine modeling, synthesis and field-based work, and adhere to the principles of reproducible, open science.
In addition, another focus of the lab is promoting diversity and inclusivity in the sciences. We advocate for women and other underrepresented groups in sciences.

Considerations for LGBTQ+ Friendly Field Work
By Rebecca Hayes for the American Society of Plant Biologists
Pride Month coincides with the middle of the field season for biologists sampling floral communities across many parts of the world. Field work often takes place in areas far from home and can require tolerating close quarters, strenuous labor, long hours, and adverse weather conditions. LGBTQ+ people face unique challenges navigating the unusual circumstances of sampling remote sites. The following are some suggestions for consideration to promote a comfortable environment for LGBTQ+ scientists if you are planning or participating in field work this summer. This list was produced based on personal experience and conversations with friends, so certainly it is non-exhaustive. Comment below if you have additional ideas! |

Explicit allyship
Make it clear that you are an ally in job postings and on websites where potential students or employees can find your contact information, most importantly when your work is conducted where it could be dangerous to be LGBTQ+. In the United States, 29 states have no anti-discrimination laws protecting LGBTQ+ people from unfair treatment based on gender or sexuality. Worldwide, there are 73 countries that criminalize same-sex sexual activity and 15 that criminalize the gender expression or identity of transgender people. Your students and employees need to know that you support them, especially if your research takes place somewhere they may feel particularly unsafe. ... read more
Oregon Quarterly: Queen of the bees
STORY BY TIM CHRISTIE
PHOTOS BY NICOLAS WALCOTT
On a brilliant, balmy, late winter’s afternoon, entomologist Lauren Ponisio walks along a ridge above the McKenzie River, through a landscape transformed by fire from a forest of Douglas fir into a blackened moonscape. She stops to inspect the remnants of a slash pile strewn with blackened stumps and snags. White flags mark the spots where she and her students had sown native plant seeds the previous fall. Amid the rubble, she spots a few green leaves poking through the ashy soil.
The plot doesn’t look like much right now. But Ponisio, an assistant biology professor at the University of Oregon, has high hopes that this pilot study could change how forestlands in the Northwest are managed, particularly post-harvest and post-fire, to the benefit of the humble, and troubled, wild bee.... read more
The Conversation: Flower mixes keep bees healthy
by Hamutahl Cohen
It’s springtime in California, and bees are emerging to feast on flowering fields – acres upon acres of cultivated almonds, oranges and other fruits and nuts that bloom all at once for just a few weeks. Farmers raise these lucrative crops in monoculture fields, each planted with neat, straight rows of a single type of crop.
The agricultural heart of California is the Central Valley, one of the most productive agricultural regions in the world. I recently drove north through the valley on Interstate 5, a 450-mile (724-kilometer) stretch of monoculture farms and agricultural land that runs from Bakersfield to Redding. Flowers were blooming as far as the eye could see. There is so much bloom here that commercial beekeepers truck in over 2 million colonies of bees in spring to ensure that every last flower is pollinated.
As a bee biologist, I study why bees are dying. Although monoculture blooms provide food for bees, scientists know almost nothing about how temporary mass-bloom events influence bee health. ... read more

Study unlocks how wild bees can survive habitat pressures
|
A research team led by University of Oregon biologist Lauren Ponisio has uncovered how native bee species may be best equipped to survive intensive agricultural practices and climate change in California’s Central Valley.
Wild bees that are persisting amid shrinking habitats are those that are flexible in their pollination behavior when around other wild bee populations, Ponisio’s team reported in a study published April 1 in Nature Ecology & Evolution. “We looked at the ability of these bees to change their roles in these plant-pollinator interaction networks,” Ponisio said. “This ability proved to be important for which species persisted in the landscape as well as for the higher number of habitat patches being occupied.”... read more |

Does urbanization homogenize the biodiversity of bees?
Postdoc Hamutahl Cohen and lab helper Sammy prepare to sample pollintors on BLM land south of Anza Borrego State Park.
|
When you think of California in the 1970s, maybe you think of hippies, Fleetwood Mac, or skateboards. But if you’re an entomologist, you might think of all the natural spaces that have since been devoured by urbanization and wonder what happened to the native bees that lived in them. The question isn’t one of mere nostalgia or curiosity. Insect populations around the world are plunging precipitously, and scientists are scrambling to understand why. The threat to pollinating insects is particularly dire because much of the food people eat depends on them.
Lauren Ponisio, an assistant professor of entomology at UC Riverside, has embarked on a project to figure out how habitat destruction has affected native bees in California by resampling sites first studied in the 1970s. It is the first systematic attempt to evaluate the extinction risk of pollinator species across California. read more... By Holly Ober |

Study finds natural fires help native bees
Press release by Jules Bernstein
Ponisio led a study to be published this month in the journal Ecology and Evolution that examined environmental factors affecting the health of native bees. There are thousands of bee species that live in the wild, many of which are found in California. Ponisio found that these native bees are better able to survive harsh climate events, like drought, in areas where naturally occurring fires are allowed to burn. read more |
As biotic communities form, pollinators swap one plant for another
Press release by Mackenzie Smith
A new study from UC Berkeley researchers helps create a clearer understanding of how networks of plants and pollinators form over time to create biotic communities. The results of their research, which could help scientists and conservationists rebuild communities when a species goes locally extinct, are published today in Ecology Letters. read more... |
How fire diversity promotes biodiversity
Press release by Julie Van Scoy
