Agroecologist Estelí Jiménez-Soto, a postdoctoral scholar/lecturer at UC Santa Cruz, does.
She will speak on "A Complex Cup of Joe: Biodiversity, Pest Control and Political Ecologies in Mexican Coffee Agroforests" at the UC Davis Department of Entomology and Nematology virtual seminar at 4:10 p.m., Wednesday, Feb 10.
Host is Extension agricultural specialist Ian Grettenberger, who coordinates the department's seminars. Access the Google form link here to attend the seminar.
"Coffeeagroforests are great for biodiversity conservation and sustain millions of families and national economies," Jiménez-Soto says in her abstract. "Within these shaded agroecosystems, a complex network of interactions and the availability of resources maintain coffee pests in check, particularly the coffee berry borer, the most devastating insect pest for coffee. Despite the importance of biodiversity conservation and maintenance of shade in these systems, the life of people is often at odds with conservation efforts and management practices, revealing social inequalities and contradictions in plantation-like agricultural systems. In this presentation, I share socio-ecological complexities in the coffee-biodiversity nexus, focusing on ants as biocontrol agents, and the everyday lived experience of farmworkers in Mexican coffee agroforests."
Overall, Jiménez-Soto describes her research as "at the intersection of agroecology and political ecology of agriculture to understand the socioecological entanglements of food production and biodiversity conservation in Mexico and the United States." Using a variety of theoretical and methodological approaches in ecology, anthropology and political ecology, she studies the mechanisms that drive species interactions, and the role of environmental change and agricultural management on insect community dynamics, ecosystem functions, and the every-day lived experience of farmers and farmworkers in coffee agroecosystems. Currently she is working on a project to assess the barriers and opportunities to the adoption of agroecological practices in strawberry production in California and Florida.
Jiménez-Soto was quoted in a National Geographic feature article, "How This Invasive Snail Could Save Your Coffee from Destruction," published on March 10, 2020. Sharing her expertise on both coffee and biocontrol measures, she told writer Forest Ray: "Classic approaches to pest control have often failed to understand this complexity, causing major natural disasters."
She holds a master's degree and doctorate in environmental studies from UC Santa Cruz, receiving her master's degree in 2015 and her doctorate in 2018.

What does climate have to do with it? And other factors?
Kilpatrick will present a seminar, hosted by the UC Davis Department of Entomology and Nematology, on "Climate, Chemicals and Evolution in the Transmission of Vector-Borne Diseases" at 4:10 p.m., Wednesday, Feb. 7 in 122 Briggs Hall.
"I will integrate findings from multiple systems, including West Nile, Zika and dengue viruses, and mosquito communities more generally, to explore the role of climate, insecticides, host-pathogen interactions, and evolution in driving spatio-temporal patterns of transmission, and the impact of vector borne diseases on their hosts," he says.
Kilpatrick says "the globalization of trade and travel will continue to move viruses, vectors and hosts to new continents and result in the emergence of vector borne diseases, as exemplified by Zika, Chikungunya and West Nile viruses. A sound understanding of the ecology and evolution of these systems is needed to address this challenge."
Kilpatrick received two bachelor's degree from UCLA (one in mechanical engineering and the other in philosophy), a master's degree in mechanical engineering from Massachusetts Institute of Technology, and a doctorate in zoology from the University of Wisconsin, Madison. He joined the UC Santa Cruz faculty in 2008 after working as a senior research scientist in the Consortium for Conservation Medicine in New York.
"My research unites theory and empirical work to address basic and applied questions on the ecology of infectious diseases as well as population biology, evolution, climate, behavior, genetics, and conservation, and I would be excited to develop collaborations and advise graduate students in any of these areas," Kilpatrick says on his website. "A key aim is to understand the underlying drivers of pathogen transmission and the impacts on host populations. My general research philosophy is to begin each project by developing a model of the system to generate hypotheses and then test these hypotheses by gathering empirical data. My current research can be divided into three general areas:
- Local determinants of pathogen transmission,
- The impact of disease on animal populations, and
- The spread of pathogens to new regions.
He focuses much of his current work in disease ecology on West Nile virus, "a mosquito-transmitted pathogen that currently causes thousands of human cases each year, as well as affecting millions of animals. However, I also work on several other pathogen systems including chytridiomycosis, Lyme disease, Brucellosis, and avian influenza."
The American Ornithologists' Union awarded him the Ned K. Johnson Young Investigator Award in 2008. The award recognizes outstanding and promising work by researchers early in their career. "Kilpatrick's research on avian influenza ("bird flu") has led to predictions about the global spread of the virulent H5N1 strain of the virus," according to a UC Santa Cruz news story. "His research on West Nile virus includes a recent study on the effects of higher temperatures on transmission of the virus by mosquitoes. He has also shown a connection between increases in human infections and dispersal of American robins, the preferred host of a mosquito species that is an important vector of West Nile virus."
The Kilpatrick seminar is part of the winter quarter schedule of seminars coordinated by assistant professor Rachel Vannette; Extension apiculturist Elina Lastro Niño and Brendon Boudinot.
