He will present his in-person seminar at 4:10 p.m. in 122 Briggs Hall. It also will be virtual; the Zoom link is https://ucdavis.zoom.us/j/99515291076.
"Twenty years ago while attempting to develop a new concept for studying insect aging in the wild, I discovered a previously unknown mathematical identity now referred to in the formal demography literature as the eponym Carey's Equality—the age distribution of a stationary population equals the distribution of lifetimes yet to come," Professor Carey says in his abstract. "In this seminar I will present my attempts at both operationalizing the concept for study of populations of insects and other non-human species, and generalizing it for applications to groups with fixed numbers of members and where renewal involves birth and death processes."
"These general applications include data from a British cemetery, the National Basketball Association, the Baltimore Longitudinal Health Study, the U.S. Congress (both chambers) and the world population," said Carey, a member of the UC Davs Department of Entomology and Nematology faculty since 1980. "After discussing implications and extensions of the identity, I will wrap up with descriptions of five simple but important demographic relations that all entomologists should know."
Highly honored for his research, teaching and public service, Carey served as the principal investigator of a 10-year, $10 million federal grant on “Aging in the Wild,” encompassing 14 scientists at 11 universities.
Biodemography Textbook. In 2020, he and Deborah Roach, professor and chair of the University of Virginia's Department of Biology, co-authored a 480-page textbook, Biodemography: An Introduction to Concepts and Methods, published by Princeton University Press and hailed as the “definitive textbook for the emerging field of biodemography, integrating biology, mathematics and demography.” Carey recently created a free-access, video guidebook with a playlist of 175 separate presentations, subtitled in 300 different languages. He storyboarded the script, turned graphs, schematics, tables and equations into animated slides, and then with teleprompter assistance, narrated and video-recorded the 175 presentations, which span 12 hours of viewing. It appears on UC Berkeley Population Sciences website at https://bit.ly/3FTge7u.
An internationally recognized teacher, Carey won a 2018 global award in the Robert Foster Cherry Award for Great Teaching Program, an academic competition sponsored every two years by Baylor University, Waco, Texas. He received the 2015 Distinguished Achievement in Teaching Award from the Entomological Society of America (ESA) and the 2014 Distinguished Teaching Award from the Pacific Branch of ESA. The UC Davis Academic Senate honored him as the recipient of its 2014 Distinguished Teaching Award, given to internationally recognized professors who excel at teaching.
Carey is a fellow of four organizations: American Association for the Advancement of Science, Entomological Society of America, California Academy of Science and the Gerontological Society of America. He holds a doctorate in entomology (1980) from UC Berkeley, and two degrees from Iowa State University: a bachelor of science degree in animal biology (1973) and a master's degree in entomology (1975).

"My lab studies the ecology and evolution of host-symbiont interactions," Wood says. "We're especially interested in the causes and consequences of conflicts that arise as hosts navigate interactions with multiple partners. I will talk about three recent projects in my lab that explore how antagonists affect host-symbiont interactions in the model mutualism between legumes and nitrogen-fixing bacteria."
As an evolutionary biologist, Wood is interested in the evolutionary ecology and evolutionary genetics of species interactions. Her research interests include ecology and biodiversity, plant biology, evolution and genetics, epigenetics and genomics.
Wood holds a bachelor of arts degree in English literature (2008) from Swarthmore (Penn.) College. She received her doctorate in biology from the University of Virginia in 2015. Her dissertation: "The Consequences of Environmental Heterogeneity for Fitness, Selection, and Inheritance."
Wood served as a postdoctoral fellow at the University of Toronto from 2015 to 2018 before accepting a faculty position at the University of Pittsburgh. She joined the University of Pennsylvania faculty in July 2020. (See profile)

Title: "Root-Knot Nematode Perception and Immune Signaling in Arabidopsis"
Host: Shahid Siddique, assistant professor, UC Davis Department of Entomology and Nematology
- Author: Kathy Keatley Garvey
Siddique served as an invited speaker and chaired a nine-presentation session on nematode-plant interactions. He also was elected to the governing board member of the European Society of Nematology (ESN), and will serve a four-year term.
Siddique, who joined the UC Davis faculty in March 2019 as an assistant professor after serving as a research group leader for several years at the University of Bonn, Germany, delivered his address on “How Plants Recognize Nematodes: Signals and Signalling.”
Siddique focuses his research on "elucidating interactions between parasitic nematodes and their hosts using molecular and basic applied methodologies." Plant-parasitic nematodes are destructive pests causing losses of billions of dollars, he says on his lab website. "While these pests have been investigated mainly because they pose a major threat to food security globally, they are also intellectually fascinating due to their highly evolved interkingdom interactions with host plants."
Coomer, who recently won a worldwide competition sponsored by the International Federation of Nematology Societies (IFNS) for her three-minute thesis on root-knot nematodes, presented her award-winning video, “Trade-Offs Between Virulence and Breaking Resistance in Root-Knot Nematode.” She received a busary as well as a certificate signed by ICN president Larry Duncan of the University of Florida and conference chair Pierre Abad of France, a senior scientist at INRA, a French public research institute dedicated to agricultural science. Coomer also showcased her work on a life-sized poster.
IFNS annually hosts the three-minute thesis competition “to cultivate student academic and research communication skills, and to enhance overall awareness of nematodes and the science of nematology.” Coomer, a doctoral student in plant pathology with an emphasis on nematology, is working on her dissertation, “Plant Parasitic Nematode Effectors and Their Role in the Plant Defense Immune System.”
The international meeting, themed “Crossing Borders: A World of Nematode Diversity and Impact to Discover" to reconcile the importance of agricultural production with that of environmental conservation, drew 682 nematologists from 57 countries. Among them were 100 student and early career scientist busary recipients. The scientific program of 32 concurrent sessions included 288 oral presentations, 12 workshops, 12 keynote speakers and more than 500 poster presentations.
It was the first in-person meeting in two years due to the COVID-19 pandemic.

Mostafa Zamanian, an assistant professor in the Department of Pathobiological Sciences, School of Veterinary Medicine, University of Wisconsin-Madison, will speak on "Combing Target and Whole-Organism Paradigms for Anthelmintic Discovery" at the May 11th virtual seminar hosted by the UC Davis Department of Entomology and Nematology.
His seminar begins at 4:10 p.m., Pacific Daylight time. The Zoom link is https://ucdavis.zoom.us/j/99515291076.
"Soil and vector-transmitted parasitic nematodes (roundworms) infect over one billion people and are a major cause of global morbidity," Zamanian says in his abstract. "Parasite control in both human and animal medicine is suboptimal and threatened by the growing prospects of anthelmintic resistance. Motivated by the need for new treatments and curiosity about basic parasite biology, I will present recent work addressing questions about how mosquito-transmitted parasitic nematodes navigate through host tissues and manipulate their host environments to survive. We will discuss how advanced transcriptomic approaches can move us towards a better understanding of the molecular basis for these essential parasite behaviors, and how we can effectively combine 'target-based' and 'whole-organism' screening pipelines to help identify novel antiparasitics."
Zamanian holds a bachelor's degree in biochemistry and a doctorate in neuroscience from Iowa State University. He served as a postdoctoral fellow at McGill University and Northwestern University before joining the faculty of the University of Wisconsin.
On his website, Zamanian relates that "Neglected Diseases (NTDs) caused by parasitic worms (helminths) impose a debilitating health and economic burden throughout much of the world. These global diseases of poverty infect over 1.5 billion humans and exert their damage through a wide range of species-specific clinical manifestations. Parasitic diseases are also a major challenge to animal and plant health. The central ambition of our laboratory is to combine molecular, genetics, and computational approaches to make discoveries that improve our understanding of parasite biology and host-parasite interactions, as well as our ability to treat parasitic infections. This includes identifying new targets for drug discovery, elucidating mechanisms of drug resistance, and developing new tools for parasite manipulation and phenotypic screening. We directly study human and animal parasites, including mosquito-borne filarial nematodes, soil-transmitted nematodes, and snail-transmitted blood flukes."

"The use of synthetic chemical pesticides is central to current agricultural practices worldwide," McArt says in his abstract. "But what is the cost to wildlife via non-target exposures? This talk will summarize when there's risk to bees, when there isn't, and what types of research are most likely to influence farmers, regulatory agencies, and policy makers."
McArt, who joined the Cornell faculty in 2017, focuses his research on pollinator health and ecology. His areas of expertise include disease ecology, ecotoxicology, community ecology, chemical ecology, and plant-pollinator interactions. He maintains his lab research site at https://blogs.cornell.edu/mcartlab/.
"Research in our lab focuses on the impact of pesticides, pathogens, and habitat on honey bees and wild bees," he writes on his website. "We are particularly interested in scientific research that can inform management decisions by beekeepers, growers and the public. Current research projects include: 1) Understanding pesticide exposure and risk to bees in multiple land management contexts, 2) Combining empirical data with network modeling to understand pathogen transmission in complex plant-pollinator networks, and 3) Understanding how habitat enhancements (e.g., flowers at solar power sites) impact pollinator populations and the services they provide to agriculture."
McArt's duties at Cornell also include director of the Cornell Chemical Ecology Core Facility, and associate curator of the Cornell University Insect Collection.
He writes a monthly column, Notes from the Lab, in American Bee Journal; each month he summarizes scientific publications for a non-scientific audience. "The goal is to make the emerging pollinator health science more approachable and relevant to beekeepers," he says.
He is also a member of the New York State (NYS) Beekeeper Tech Team, which works directly with NYS beekeepers to improve honey bee health, reduce colony losses, and increase profitability of the state's beekeeping industry: https://pollinator.cals.cornell.edu/nys-beekeeper-tech-team/
In addition, McArt coordinates such beekeeping workshops as "Introduction to Honey Bee Queen Rearing" and "Honey Bee Biology and Disease Management for Veterinarians" and engages with growers regarding pesticide risk to bees and creating pollinator-friendly habitat. His extension materials are onsite.
When asked "What gets you out of bed in the morning?" during a new faculty interview, he responded "Most of the factors contributing to declines in bee health (pesticide exposure, lack of floral resources, disease, inadequate management practices) are preventable. With targeted research efforts and educated stakeholders, regulatory agencies and public, we can make a difference."
McArt holds a bachelor of arts degree in environmental and evolutionary biology (2001) from Dartmouth College, Hanover, N.H., and a master's degree in biological sciences (2006) from the University of Alaska, Anchorage. He received his doctorate in entomology in 2012 from Cornell University. He served as a USDA-NIFA (National Institute of Food and Agriculture) postdoctoral fellow at the University of Massachusetts, Amhurst, in 2014, and then as a research scientist at Cornell from 2014 to 2017, before joining the Cornell faculty.
