Wargin, to receive her bachelor's degree in entomology in June (she is minoring in ecology and comparative literature), holds a near straight-A grade point average. Plans to present the awards are pending due to coronavirus pandemic precautions.
Wargin is a member of the highly competitive Research Scholars Program in Insect Biology (RSPIB), founded and co-directed by faculty members Jay Rosenheim, Joanna Chiu and Louie Yang of the UC Davis Department of Entomology and Nematology. As part of RSPIB, Wargin joined the lab of Stacey Combes, associate professor, Department of Neurology, Physiology, and Behavior, to research the biomechanics and behavioral ecology of flying insects.
Combes described her as “one of the most promising undergraduates I have ever worked with in terms of her potential for research and a career in academia.”
Academic advisor Sharon Lawler, professor of entomology, praised Wargin's academic record, zeal and communication skills. “She is an extraordinarily talented and hard-working scholar. Her achievements and clear research focus promise early and extended success.”
For the past year, Wargin has been working on an experiment investigating the effects of changing barometric pressure on bumble bee (Bombus impatiens) foraging behavior. She presented the preliminary results at the 2020 annual meeting of the Society of Integrative and Comparative Biology in January.
As part of her research, Wargin built a device to “experimentally control pressure using a plexiglass box, which could hold an entire hive of bees and a nectar source, a solenoid valve system connected to an air source and vacuum, and a variety of cameras to record behavior.”
“I subjected the hive inside the box to two pressure regimes in my preliminary trial: increasing pressure and decreasing pressure,” Wargin said. “With the cameras, I captured images of individually tagged worker bees leaving and returning to the hive during foraging, as well as videos of the inside of the nest to observe overall activity.”
“Currently, I have completed a preliminary trial of this experiment,” the UC Davis senior said. “I am now refining the methodology and working out a few issues I had with data collection in order to streamline future trials and improve the scope of the data I collect. While I don't have enough data for publishable results, I have discovered from my preliminary trial that pressure does appear to have some effect on bumble bee foraging behavior. Specifically, when the pressure is decreasing, the bees tend to be more active; they go on more foraging trips and are slightly busier inside the nest. When the pandemic has calmed down a bit and I am able to return to lab, I hope to complete a few more trials and publish the results.”
“Last spring, Annaliese and I began discussing ideas for an independent research project for her to conduct during her senior year,” Combes said. “She became excited about the idea of experimentally testing the effects of barometric pressure changes (which often precede storms and other changes in weather) on bumble bee foraging and nest care behavior. Anecdotal accounts of the effects of pressure changes on bees and other animals abound, but experiments have rarely been performed on this topic in a controlled setting – partly because it's not entirely straightforward how to design a system that allows one to control and alter barometric pressure. “
“However, Annaliese dove right into this challenge and set about designing a custom-built, air-tight enclosure to house a colony of bees and their foraging chamber,” Combes said. “She spent several months constructing this system--researching and ordering proportional solenoid valves to precisely control inflow and outflow from the chamber (to alter pressure) and designing camera systems to automatically capture videos of in-hive behavior as well as motion-activated photographs of individual foragers that she marked with QR-code tags. Annaliese succeeded in producing a system to test her questions and conducted a preliminary experiment over several weeks on one hive this summer. The results are very promising, and we plan to follow up with several more experiments on additional hives this year.
Said Combes: “Annaliese's creativity in research questions and approaches, her determination in designing and trouble-shooting a very difficult technical set-up, and her diligence in collecting rigorous data for hours on end have resulted in what I think will be some novel and very important findings about how a ubiquitous environmental variable affects the behavior of key pollinators. I anticipate this research resulting in a high-impact publication over the next year, with Annaliese as the lead author.”
In addition, she has “devoted herself to outreach and to sharing her extraordinary passion for insects with the general public, and especially with girls and women,” Combes said. “She has always loved insects and was initially mystified when many of her classmates (especially girls) seemed scared of these creatures.”
A native of Rancho Palos Verdes, a suburb in Los Angeles County, Annaliese developed her interest in insects in early childhood. “I spent the early years of my life in Chicago, where I had a few encounters with insects like cicadas, mantises and bees,” she related. “These experiences sparked my interest and inspired me to pursue a career that was closely connected to the natural world. I went through a few different phases when I was a teenager when it came to what I wanted to do in college, but all of them were related to the biological sciences, and I eventually decided to do what I always did--spend a lot of time looking at and learning about insects. That initial fascination with insects has since developed into a broad interest in the fields of insect behavior and insect ecology.”
As a teen-ager, Annaliese won the prestigious Girl Scout Gold Award, the highest Girl Scout honor, for her 80-hour self-led service project focused on insect outreach. She delivered several presentations to children in her community about insects and their importance to the natural world. The award honors the “dreamers and the doers who take ‘make the world a better place' to the next level, according to the Girl Scout Association.
An active member of the Entomology Club, Wargin worked with advisor Bob Kimsey and fellow members in 2018 to collect data on Alcatraz Island for the National Park Service. They surveyed old buildings for beetle damage and set up experimental trials for future data collection. In addition, Wargin served as a student researcher in the Department of Evolution and Ecology in 2019, and worked on a native pollinator project in the summer of 2017 at the Palos Verdes Peninsula Land Conservancy.
Wargin's seven academic scholarships include the UC Davis McBeth Memorial Scholarship, given to entomology students who plan to further their education in the field.
Her future plans? “I plan to attend graduate school and earn a PhD in insect ecology,” Wargin said. “I feel drawn to research and am excited about what I'll study in the future. “

Lynn Kimsey (lskimsey@ucdavis.edu), director of the Bohart Museum of Entomology and UC Davis professor of entomology, is coordinating the event, with Professor Neal Williams assisting.
Thorp, 85, passed away Friday, June 7 at this home in Davis. He would have been 86 on Aug. 26.
Thorp, a member of the UC Davis entomology faculty for 30 years, from 1964-1994, achieved emeritus status in 1994 but continued to engage in research, teaching and public service until a few weeks before his death.
A tireless advocate of pollinator species protection and conservation, Thorp was known for his expertise, dedication and passion in protecting native pollinators, especially bumble bees, and for his teaching, research and public service. He was an authority on pollination ecology, ecology and systematics of honey bees, bumble bees, vernal pool bees, conservation of bees, native bees and crop pollination, and bees of urban gardens and agricultural landscapes.
“Robbin's scientific achievements during his retirement rival the typical career productivity of many other academic scientists,” said Steve Nadler, professor and chair of the UC Davis Department of Entomology and Nematology. “His contributions in support of understanding bee biodiversity and systematics are a true scientific legacy.
Said Kimsey: "Robbin had a long, well-respected career in pollination biology and bee taxonomy, but when he retired, he became even more engaged. He became the go-to person for everyone working on pollination in the western states. Many careers were made with his assistance."
"I've known Robbin since I was a graduate student at UC Davis," Kimsey said. "Even though he wasn't my major professor, my project was on bees and he was incredibly helpful and supportive. His enthusiasm about pollinators and bees in particular actually grew after he retired, and he continued helping students and researchers and was the backbone of so much research. His support and kindness was matched by his undemanding assistance and expertise. What a terrible loss to his family and to the research and conservation communities."
In his retirement, Thorp co-authored two books Bumble Bees of North America: An Identification Guide (Princeton University, 2014) and California Bees and Blooms: A Guide for Gardeners and Naturalists (Heyday, 2014). Locally, he was active in research projects and open houses at the Bohart Museum of Entomology and the Häagen-Dazs Honey Bee Haven, a half-acre bee garden on Bee Biology Road operated by the UC Davis Department of Entomology and Nematology. He detected and identified more than 80 species of bees in the haven.
Born Aug. 26, 1933 in Benton Harbor, Mich., Thorp received his bachelor of science degree in zoology (1955) and his master's degree in zoology (1957) from the University of Michigan, Ann Arbor. He earned his doctorate in entomology in 1964 from UC Berkeley, the same year he joined the UC Davis entomology faculty. He taught courses from 1970 to 2006 on insect classification, general entomology, natural history of insects, field entomology, California insect diversity, and pollination ecology.
Every summer from 2002 to 2018, Thorp volunteered his time and expertise to teach at The Bee Course, an annual workshop sponsored by the American Museum of Natural History and held at the Southwestern Research Station, Portal, Ariz. The intensive 9-day workshop, considered the world's premiere native bee biology and taxonomic course, is geared for conservation biologists, pollination ecologists and other biologists.
Highly honored by his peers, Thorp was named a fellow of the California Academy of Sciences, San Francisco in 1986; recipient of the Edward A. Dickson Emeriti Professorship of UC Davis in 2010; and recipient of the UC Davis Distinguished Emeritus Award in 2015. Other honors included: member of the UC Davis Bee Team that won PBESA's Team Award in 2013. In addition, he was a past president (2010-2011) of the Davis Botanical Society, and former chair (1992-2011) of the Advisory Committee for the Jepson Prairie Reserve, UC Davis/Natural Reserve System.
Professor Neal Williams, who organized a symposium in Dr. Thorp's honor at the 2019 Pacific Branch, Entomological Society of America (PBESA) meeting in San Diego, said: ‘Through his tireless efforts in research, advocacy and education, he has inspired a new generation of bee researchers…I like many others, feel truly honored, to have received the mentoring of Robbin and to have him as a colleague.”
Williams said the PBESA symposium was “perhaps the greatest honor one can receive from close colleagues--a special symposium honoring him and his contributions to the field of bee biology and pollination. We designed the symposium to honor the impact of Dr. Thorp, on the field of bee biology and conservation, but at the same time present innovative research that brings together bee and pollination biology researchers."
An authority on the critically imperiled Franklin's bumble bee, Bombus franklini, Thorp began monitoring the bumble bee population in 1998 in its narrow distribution range of southern Oregon and northern California. He had not seen it since 2006 and was instrumental in placing the bee on the Red List of Threatened Species of the International Union for Conservation of Nature and Natural Resources (IUCN). He was the former regional co-chair of the North America IUCN Bumblebee Specialist Group.
In August of 2016 a documentary crew from CNN, headed by John Sutter, followed Thorp to a meadow where Thorp last saw Franklin's bumble bee. Sutter wrote about Thorp, then 82, in a piece he titled "The Old Man and the Bee," a spinoff of Ernest Hemingway's "The Old Man and the Sea."

Dr. Robbin Thorp, a global and legendary authority on bees and a distinguished emeritus professor of entomology at the University of California, Davis, passed away Friday, June 7 at his home in Davis, surrounded by family. He was 85.
Dr. Thorp, a member of the UC Davis entomology faculty for 30 years, from 1964-1994, achieved emeritus status in 1994 but continued to engage in research, teaching and public service until a few weeks before his death.

His support and kindness was matched by his undemanding assistance and expertise. What a terrible loss to his family and to the research and conservation communities."
Colleague Norman Gary, UC Davis emeritus professor of entomology, commented earlier this year in a letter of support for a College of Agricultural and Environmental Sciences award: “Robbin is recognized internationally for his expertise and research on bees, especially non-Apis species, known as wild bees. I doubt that there is anyone else in the world who can compete with his expertise in the systematics of the 20,000 species of bees on this earth. He has the perfect balance of research of field research on the biology and behavior as well as laboratory research on the taxonomy of bees.” He was the go-to person to identify a bee by species.
Professor Neal Williams, who organized a symposium in Dr. Thorp's honor at the 2019 Pacific Branch, Entomological Society of America meeting in San Diego, said: ‘Through his tireless efforts in research, advocacy and education, he has inspired a new generation of bee researchers…I like many others, feel truly honored, to have received the mentoring of Robbin and to have him as a colleague.”

Leslie Saul-Gershenz, who received her doctorate in entomology from UC Davis and is now an associate director of research with the Wild Energy Initiative, John Muir Institute of the Environment, said “I am heartbroken. I really hoped with all my heart that Robbin was going to get better and we would have more time with him, more of his sweetness, his kindness, his caring. He helped so many people over so many decades, his contributions were immense in his scientific contributions but also in his positive support of students, and colleagues alike and encouragement of public engagement. I miss him so much. “
Williams said the PBESA symposium was “perhaps the greatest honor one can receive from close colleagues--a special symposium honoring him and his contributions to the field of bee biology and pollination. We designed the symposium to honor the impact of Dr. Thorp, on the field of bee biology and conservation, but at the same time present innovative research that brings together bee and pollination biology researchers."
Richard Hatfield, a senior conservation biologist with Xerces' Endangered Species Program presented him with a framed illustration of Bombus franklini, the work of artist April Coppini of Portland, Ore. An authority on Franklin's bumble bee, Dr. Thorp began monitoring the bumble bee population in 1998 in its narrow distribution range of southern Oregon and northern California. He has not seen it since 2006 and was instrumental in placing Franklin's bumble bee on the Red List of Threatened Species of the International Union for Conservation of Nature and Natural Resources (IUCN). Long active in the North America IUCN Bumblebee Specialist Group, Dr. Thorp served as its regional co-chair, beginning in 2011.

“Robbin has done so much for me over the years,” Hatfield said. “I'm pleased to give back even a small fraction.” Hatfield praised him as a “a Living Legend of North American Bee Conservation” in a Xerces Society blog during Earth Week. “He has made lasting contributions to the bee conservation community in ways that might never be measured, but will certainly be felt.” https://xerces.org/2019/04/24/robbin-thorp-earth-week/.
"It was great to see Robbin interacting and enjoying the conference and the company," said Professor Gordon Frankie of UC Berkeley, one of the speakers at the Robbin Thorp Symposium. "We all have learned much from him over the years, and this was a good occasion to say thanks and acknowledge Robbin's many contributions."
Professor Diane Ullman, former chair of the UC Davis Department of Entomology, said: “Robbin was my faculty advisor when I was a student! He gave me the courage to stay in graduate school and was a wonderful supporter when I came back to Davis as a faculty member. He was an amazing and passionate scientist and an extraordinary person.”
More tributes:
Eric Mussen, Extension apiculturist emeritus: "We should not forget that Robbin originally was hired to work on honey bees, and he did. His greatest area of expertise was the use of honey bees in almond pollination. Robbin determined that until the colonies reached the population size of six frames of bees, they did not have enough spare bees to serve as foragers (pollinate almonds) since they were all needed to keep the brood warm. He also noted that the amount of pollen collected by the bees in a colony was pretty much in direct proportion to colony size, peaking at between 10 and 12 frames of bees. It was obvious to Robbin that the bees still visited almond blossoms for nectar, days after there was no pollen left in the flowers and the stigmata were no longer young enough to be pollinated. Other studies determined which blossoms along the branches were pollinated earlier and later during the season. All of those studies were very well designed and the results contributed significantly to our recommendations to growers and beekeepers for obtaining maximum benefit from the bees."
Professor Claire Kremen of the University of British Columbia, formerly of UC Berkeley, praised him in her letter of support for his nomination for distinguished emeritus professor in 2014:
"I have had the privilege of working with Dr. Thorp as a close colleague since 1999. I can definitely say that without his contributions, I could never have developed as extensive and impactful a research program on pollinator conservation and pollination services. It is even more noteworthy that Dr. Thorp's contributions to this research program have all occurred since his 'retirement'– he has had a very active retirement indeed."
"Dr. Thorp has contributed in three main ways. First, he has provided expert input into the design of protocols for the research, including assays for pollinator effectiveness, developing citizen science methods, rearing experimental bumble bee colonies, monitoring bumble bee colony properties in the field, and developing pollinator survey methods. Second, he has provided expert taxonomic services, including personally identifying over 100,000 native bee specimens that we have collected during this work, and working with us to develop a bee traits database. Third, he has trained numerous field assistants and graduate students from my lab in different aspects of bee biology. He's spent long hours with many of my graduate students helping them learn to identify bees. He also helped us develop methods and information sheets for teaching field and lab teams to recognize key generic and family characters for identifying bees in the field and sorting them in the lab. He's advised many of my graduate students on different aspects of their work.
"Collectively, Dr. Thorp's contributions have impacted 35 publications that have emerged from this research program to date, with many more either submitted or nearing the submission stage. He has also been a co-author on a number of these publications. Not only has Dr. Thorp had such a significant effect on the work of my lab, but he conducts his own primary work documenting the status of rare bumble bee species like Bombus franklini and B.occidentalis and contributes at a similar level to other research labs such as with his long-time collaborators Dr. Gordon Frankie and Dr. Neal Williams. It's really quite amazing how he manages to do it all."
In another letter of support, Katharina Ullmann, director of the UC Davis Student Farm, Agricultural Sustainability Institute, and a UC Davis alumnus (doctorate in entomology) wrote:
"I met Robbin Thorp in 2007 and assumed that he was an active professor because of his continued contribution to the field of entomology, teaching activities, publishing in peer-reviewed journals and vocal support of pollinator conservation efforts. For these reasons I considered asking if I could join his lab. I remember telling someone my plan and they said 'That probably won't work. Robbin is retired.' He does so much in the field of pollination ecology that I didn't even realize he was retired.
"...The entire time that I've known Robbin I've been impressed with (1) his depth and breadth of knowledge about bees and crop pollination, (2) his willingness to share what he knows, and (3) how approachable he is. It doesn't matter if you're a MacArthur Genius or a field technician just learning about bees, Robbin always makes time to talk with you and answer your questions.
"Robbin is one of the few people in North America who can identify bees down to the species level,” Ullmann said. As a result he's in high demand and has identified thousands of specimens for numerous lab groups since his retirement. However, he doesn't just identify the specimens. Instead, he's willing to patiently work through dichotomous keys with you so that you can learn those skills."
Research entomologist James Cane of USDA's Agricultural Research Service, Logan, Utah, wrote in 2014 that “Dr. Robbin Thorp should be the first scientist to be cloned, so valuable and broadly integrated are his knowledge about bees and pollination. No one else I know has his combination of skills; normally several people would be needed. Thus, he is a taxonomist of several genera of bees, a competent pollination biologist studying both native bees and honey bees in both natural and agricultural realms (with research experience in several crops), and a conservation advocate for bees. Moreover, I have watched his considerable teaching skills while helping in The Bee Course over the years. There I also get to see what a model human being Robbin is: thoughtful, considerate, a great listener, playful, polite unpretentious, all traits that the students gravitate towards. I have looked to Robbin as a role model for over 30 years, listen carefully to what he has to say, and always look forward to being in his presence. UC Davis is very lucky indeed to have attracted and retained such a fabulous faculty member.”
Ron McGinley, an instructor an organizer of The Bee Course, said “Robbin Thorp converted me from bugs to bees. To say that Robbin changed my life would be a vast understatement! In retirement, Robbin continues to be one of the most highly regarded bee workers in the world. He also continues his outstanding educational/mentoring skills.”
McGinley shared several comments from The Bee Course alumni:
- It was really a pleasure to learn from one of the best "Bee Dudes” out there.
- Professors with a great deal of experience can sometimes find it difficult to teach students who are just being introduced to the material. Their command of the material is so great that it seems second nature and they can forget how to guide students through the labyrinths of taxonomic structures. Not so for Dr. Robbin Thorp. The paths laid out for students in The Bee Course were clear and the light at the end of the tunnel, although sometimes faint, was always visible.
- Robbin even bought me a Dairy Queen treat for being the first to find an active bee nest….Centris. I said ‘Robbin, you don't have to buy me this treat' and he answered ‘Yes, I do, it's tradition.'
- Robbin is fun to be with in the field and welcomes questions for which he gives very clear answers.
- I sincerely hope that I will meet and work with Robbin again in the future. He is just a joy to be with.
Stephen Clement, emeritus lead scientist and research entomologist with the USDA's Agricultural Research Service, said "He welcomed me back to the department in 1970 after I got out of the Army and a year of combat in Vietnam. He was my major professor for my master of science degree, which I completed in 1972. I did the field research in Yellowstone National Park and he ventured up to the park to mentor my field work (special memories of the time I spent with Robbin in the Park). Robin was instrumental in my development as a field biologist. I had hoped he would be at the recent reunion but now know he was at the ESA Pacific Branch meeting where there was a symposium in his honor."
Dr. Thorp was known for his public service, his response to all requests for bee identifications, and his friendships.
Insect photographer Allan Jones of Davis: “I feel particularly privileged as an outsider to have drawn his friendship, attention and support. A picture is said to be worth a thousand words. But a picture with accurate text is a treasure. He has been adding depth and meaning for all of the visitors and friends he has kindly touched.”
Naturalist and bumble bee enthusiast Gary Zamzow of Davis said that “Dr. Thorp frequently helped the Wisconsin Arboretum staff and volunteers. He identified the bumble bees photographed at the Arboretum and other areas. He would confirm our identifications. A great learning experience for all of us. We could have not done it without Dr. Thorp's help.”
His wife, Joyce, 84, preceded him in death on Dec. 9, 2018. Survivors include three children, Kelly, Katie and Jeff, and stepchildren Donna Gary and Steve Gary.

“He received what is perhaps the greatest honor one can receive from close colleagues, a special symposium honoring him and his contributions to the field of bee biology and pollination,” said coordinator and pollination ecologist Neal William, professor of entomology, UC Davis Department of Entomology and Nematology. Several of the leading bee biologists in western North America assisted with the symposium.
“It was known as The Robbin Symposium and colleagues old and new gathered the hear a supercharged line up present current research that has been directly impacted by Robbin Thorp,” Williams said. "We designed the symposium to honor the impact of Dr. Thorp, on the field of bee biology and conservation, but at the same time present innovative research that brings together bee and pollination biology researchers."
The symposium featured scientific contributions from leaders in the fields of bee ecology, conservation and pollination, all who worked with or were influenced by Thorp:
- Claire Kremen, University of British Columbia, formerly of UC Berkeley
- James Strange, USDA's Agricultural Research Service Heidi Dobson, Whitman College, Walla Walla, Wash.
- Gretchen Lebuhn, San Francisco State University
- Richard Hatfield, Xerces Society for Invertebrate Conservation
- Terry Griswold, USDA's Agricultural Research Service
- Neal Williams, UC Davis
- Leslie Saul-Gershenz, UC Davis
- Gordon Frankie, UC Berkeley
Hatfield, a senior conservation biologist with Xerces' Endangered Species Program presented him with a drawing of Bombus franklini, the work of artist April Coppini of Portland, Ore. An authority on Franklin's bumble bee, Thorp has monitored the bumble bee population since 1998 in its narrow distribution range of southern Oregon and northern California. He has not seen it since 2006 and it is feared extinct. In August of 2016 a documentary crew from CNN, headed by John Sutter followed him to a meadow where Thorp last saw Franklin's bumble bee. He wrote about Thorp, then 82, in a piece he called "The Old Man and the Bee," a spinoff of Ernest Hemingway's "The Old Man and the Sea." (See more on Franklin's bumble bee at https://xerces.org/franklins-bumble-bee/)
“Robbin has done so much for me over the years,” Hatfield said. “I'm pleased to give back even a small fraction.” Hatfield blogged about him during Earth Week. https://xerces.org/2019/04/24/robbin-thorp-earth-week/.
At the social event that followed, attendees shared their gratitude with Thorp "for his lifetime of work, mentoring and friendship,” Williams said.
"It was great to see Robbin interacting and enjoying the conference and the company," Frankie said. "We all have learned much from him over the years, and this was a good occasion to say thanks and acknowledge Robbin's many contributions."
Thorp, a member of the UC Davis entomology faculty for 30 years, from 1964-1994, achieved emeritus status in 1994 but has continued to engage in research, teaching and public service. In his retirement, he co-authored two books Bumble Bees of North America: An Identification Guide (Princeton University, 2014) and California Bees and Blooms: A Guide for Gardeners and Naturalists (Heyday, 2014).
A tireless advocate of pollinator species protection and conservation, Thorp is known for his expertise, dedication and passion in protecting native pollinators, especially bumble bees, and for his teaching, research and public service. He is an authority on pollination ecology, ecology and systematics of honey bees, bumble bees, vernal pool bees, conservation of bees, contribution of native bees to crop pollination, and bees of urban gardens and agricultural landscapes.

The intensive 9-day workshop, considered the world's premiere native bee biology and taxonomic course, is geared for conservation biologists, pollination ecologists and other biologists who want to gain greater knowledge of the systematics and biology of bees.
Thorp was named a fellow of the California Academy of Sciences, San Francisco in 1986; recipient of the Edward A. Dickson Emeriti Professorship of UC Davis in 2010; and recipient of the UC Davis Distinguished Emeritus Award in 2015. Other honors include: member of the UC Davis Bee Team that won PBESA's Team Award in 2013. In addition, he is a past president (2010-2011) of the Davis Botanical Society, and former chair (1992-2011) of the Advisory Committee for the Jepson Prairie Reserve, UC Davis/Natural Reserve System.
Since its inception, Thorp has been involved in the Häagen-Dazs Honey Bee Haven, a half-acre bee garden on Bee Biology Road operated by the UC Davis Department of Entomology and Nematology, installed in 2009. To establish a baseline, he began monitoring the site for bees in 2008. He has since detected more than 80 species of bees.

He's spent long hours with many of my graduate students helping them learn to identify bees. He also helped us develop methods and information sheets for teaching field and lab teams to recognize key generic and family characters for identifying bees in the field and sorting them in the lab. He's advised many of my graduate students on different aspects of their work.
"Collectively, Dr.Thorp's contributions have impacted 35 publications that have emerged from this research program to date, with many more either submitted or nearing the submission stage. He has also been a co-author on a number of these publications. Not only has Dr. Thorp had such a significant effect on the work of my lab, but he conducts his own primary work documenting the status of rare bumble bee species like Bombus franklini and B.occidentalis and contributes at a similar level to other research labs such as with his long-time collaborators Dr. Gordon Frankie and Dr. Neal Williams. It's really quite amazing how he manages to do it all."
"He also teaches regularly in The Bee Course, a field course held in Arizona each year by the American Museum of Natural History, frequently gives talks and workshops that educate our state agencies and the public about the importance of pollinators, and works with conservation organizations like the Xerces Society to promote pollinator conservation."
In another letter of support, Ullmann, director of the UC Davis Student Farm, Agricultural Sustainability Institute, who received her doctorate in entomology from UC Davis, wrote:
"I met Robbin Thorp in 2007 and assumed that he was an active professor because of his continued contribution to the field of entomology, teaching activities, publishing in peer-reviewed journals and vocal support of pollinator conservation efforts. For these reason I considered asking if I could join his lab. I remember telling someone my plan and they said 'That probably won't work. Robbin is retired.' He does so much in the field of pollination ecology that I didn't even realize he was retired.
"Since then I've had the privilege of interacting with Robbin as a field technician, a graduate student in the Department of Entomology at UC Davis, a student at The Bee Course, a co-presenter at a bee identification course for US Forest Service staff, and as a co-author on a peer-reviewed paper. The entire time that I've known Robbin I've been impressed with (1) his depth and breadth of knowledge about bees and crop pollination, (2) his willingness to share what he knows, and (3) how approachable he is. It doesn't matter if you're a MacArthur Genius or a field technician just learning about bees, Robbin always makes time to talk with you and answer your questions.
"Robbin is one of the few people in North America who can identify bees down to the species level. As a result he's in high demand and has identified thousands of specimens for numerous lab groups since his retirement. However, he doesn't just identify the specimens. Instead, he's willing to patiently work through dichotomous keys with you so that you can learn those skills."

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.
