Mola, a U.S. Geological Survey Mendenhall Postdoctoral Fellow based at the Fort Collins Science Center, Colorado, and a former member of the Neal Williams laboratory, UC Davis Department of Entomology and Nematology, authored the research review article with colleagues Jeremy Hemberger, a postdoctoral researcher in the Williams lab; Jade Kochanski of the University of Wisconsin, Madison; Leif Richardson of the Xerces Society for Invertebrate Conservation; and UC Davis alumnus Ian Pearse of the Fort Collins Science Center.
Photographer Diego Delso took the cover image showing a Bombus terrestris, a buff-tailed bumble bee that is one of the most numerous bumble bee species in Europe. He captured the image on a pink mulla mulla, Ptilotus exaltatus, in Estonia.
The abstract:
"Declines of many bumble bee species have raised concerns because of their importance as pollinators and potential harbingers of declines among other insect taxa. At present, bumble bee conservation is predominantly focused on midsummer flower restoration in open habitats. However, a growing body of evidence suggests that forests may play an important role in bumble bee life history. Compared with open habitats, forests and woody edges provide food resources during phenologically distinct periods, are often preferred nesting and overwintering habitats, and can offer favorable abiotic conditions in a changing climate. Future research efforts are needed in order to anticipate how ongoing changes in forests, such as overbrowsing by deer, plant invasions, and shifting canopy demographics, affect the suitability of these habitats for bumble bees. Forested habitats are increasingly appreciated in the life cycles of many bumble bees, and they deserve greater attention from those who wish to understand bumble bee populations and aid in their conservation."
They pointed out that "Bumble bee conservation and management has garnered considerable attention because of bees' role as pollinators of economically and ecologically important crops and wild plants. The precipitous decline of several bumble bee species has been documented in the twenty-first century, raising alarm about the viability of these charismatic species (Cameron and Sadd 2020). Because of this, bumble bees have become a focal taxon for understanding and preventing the loss of insect biodiversity more broadly (Goulson and Nicholls 2016, Wagner et al. 2021). Threats to bumble bee populations include habitat loss, novel pathogen exposure, climate change, and pressures from intensive agriculture, such as pesticide applications (Cameron and Sadd 2020). One of the primary tasks for bumble bee conservation is developing a greater understanding of the habitat requirements of species throughout their life cycle and incorporating that knowledge into restoration and management plans."

An invited participant on the Western Bumble Bee Species Status Assessment Expert Group and the Native Bee Monitoring Research Coordination Network, Mola is also an organizing member (since 2020) of BOMBUSS: Building Our Methods by Using Sound Science.
Mola, who holds a bachelor of science degree in environmental studies from Florida State University, and a master's degree in biology from Humboldt State University, received his doctorate in ecology in 2019 from UC Davis. He presented his exit seminar on "Bumble Bee Movement Ecology and Response to Wildfire."
Mola also was a UC Davis Professors for the Future Fellow, receiving a year of professional development and pedagogical training. His honors also include a 2013-2018 National Science Foundation Graduate Research Fellowship of $133,500 and a 2014-2016 UC Davis Graduate Group in Ecology Fellowship of $43,000. He won the graduate student research poster competition at the 2018 UC Davis Bee Symposium for his work on "Bumble Bee Movement and Landscape Genetics."

Judges were Tom Seeley, professor at Cornell University, the symposium's keynote speaker; speaker Santiago Ramirez, assistant professor of evolution and ecology at UC Davis, and native pollinator specialist Robbin Thorp, distinguished emeritus professor at UC Davis. Master beekeeper/journalist Mea McNeil of San Anselmo served as the timer and coordinator for the panel.
“In conservation biology and ecological study, we must know the distances organisms travel and the scales over which they go about their lives,” Mola said of his work. “To properly conserve species, we have to know how much land they need, how close those habitats need to be to each other, and the impact of travel on species success. For instance, if I'm told there's free burritos in the break room, I'm all over it. If the 'free' burritos require me traveling to Scotland, it's not worth it and I would spend more energy (and money) than I would gain. For pollinators, it's especially important we understand their movement since the distances they travel also dictates the quality of the pollination service they provide to crop and wild plants."
Second place of $600 went to Maureen Page, a second-year Ph.D. student in Neal Williams lab for her research, “Impacts of Honey Bee Abundance on the Pollination of Eschscholzia californica (California golden poppy).”
Page presented her research on the impacts of honey bee abundance on native plant pollination. “While honey bees are economically important, they are not native to North America and may have negative impacts on native bees and native plant communities in certain contexts,” she related. “My research is ongoing, but preliminary results suggest that honey bee abundance may negatively affect the pollination of California poppies.”
In her abstract, Page wrote: "Many studies support the claim that introduced honey bees compete with native pollinators. However, little is known about how honey bee introductions will affect native plant communities and plant species' persistence."
Page received her bachelor's degree in biology from Scripps College, Claremont, Calif. in 2006, cum laude. She seeks a career as a professor and principal investigator.
Two graduate students tied for fourth place and each received $250: doctoral student Jacob Francis of the University of Nevada, for his “A Sweet Solution to the Pollen Paradox: Nectar Mediates Bees' Responses to Defended Pollen” and Katie Uhl, a master's student, UC Davis Department of Food Science and Technology, for her “Determination of Volatile Organic Compounds in Mono-Floral Honey Using HS-SPME/GC/MS." Francis studies with major professor Anne Leonard of Ecology, Evoluiton and Conservation Biology. Uhl's major professor is Alyson Mitchell.
Also honored was Kimberly Chacon, a doctoral student in the UC Davis Geography Graduate Group who studies with Professor Steve Greco for her “A Landscape Ecology Approach to Bee Conservation and Habitat Design." She received $150.
The annual Bee Symposium, themed "Keeping Bees Healthy, " is sponsored by the UC Davis Honey and Pollination Center, headed by director Amina Harris, and the UC Davis Department of Entomology and Nematology, chaired by nematologist and professor Steve Nadler.
Harris and Professor Neal Williams of the Department of Entomology and Nematology, who serves as the center's faculty co-chair, emceed the symposium. The symposium drew a crowd of 250 from across the country.
