Hölldobler, an evolutionary biologist based at Arizona State University researches the evolution and social organization in ants. He says that colonies that are "true superorganisms, show great cooperation among their nest mates and exhibit fierce aggression against neighboring conspecific colonies and display complex territorial strategies." His experimental and theoretical contributions cover sociobiology, behavioral ecology, and chemical ecology.
Hölldobler and co-author E. O. Wilson won the Pulitzer Prize for non-fiction writing in 1990 for their book, The Ants. They also co-authored The Superorganism: The Beauty, Elegance, and Strangeness of Insect Societies and Journey to the Ants: A Journey of Scientific Exploration. Hölldobler is also the author of The Leafcutter Ants.
A native of Bavaria, Germany (born June 25, 1936), he studied biology and chemistry at the University of Würzburg. He wrote his doctoral thesis on the social behavior of the male carpenter ant and their role in the organization of carpenter ant societies.
Hölldobler began his academic career at the University of Frankfurt in 1971 as a professor of zoology. From 1973 to 1990 he served as professor of biology and the Alexander Agassiz professor of zoology at Harvard University, Cambridge, Mass. Hölldobler returned to Germany in 1989 to accept the chair of behavioral physiology and sociobiology at the Theodor-Boveri-Institute of the University of Würzburg.
From 2002 to 2008, Hölldobler was an Andrew D. White Professor-at-Large at Cornell University, Ithaca, N.Y. Since his retirement in 2004, he has worked at Arizona State University (ASU) as a professor and research scientist. A Regents' and Foundation professor, he is one of the founders of the Social Insect Research Group (SIRG) and of the Center for Social Dynamics and Complexity.
The seminars are coordinated by medical entomologist/assistant professor Geoffrey Attardo and take place at 4:10 p.m. every Wednesday through June 5 in 122 Briggs Hall. (See list of seminars)/span>
Doctoral candidate and nematologist Corwin Parker of the Steve Nadler lab won the Picnic Day design with his illustration of a bee barbecuing.
And an ant design for a onesie, “My Sister Loves Me,” by doctoral student and ant specialist Jill Oberski of the Ward lab rounds out the winners' circle.
Boudinot, a fourth-year doctoral student and president of EGSA, said the ant featured on his design “is a minor worker of the Drogon ant and described recently by our post-doc Eli Sarnat." Sarnat, who received his doctorate in entomology from UC Davis in 2009, is now a post-doctorate researcher in the Okinawa Instituite of Science and Technology in the Economo lab. The ant in Boudinot's design is based on Sarnat's work, published in AntWiki and in The Guardian.
Oberski's adult ant is “loosely based on Ochetellus, a mostly-Australian genus.” After admiring an image taken by Alex Wild, also a Phil Ward lab alumnus (doctorate in entomology in 2005) and “I went from there.” Wild, a renowned macro photographer, is the curator of Entomology at the University of Texas/Austin.
The winning T-shirts and other previous winners can be ordered online at https://mkt.com/UCDavisEntGrad/ and also will be available at Briggs Hall on April 21 at the annual UC Davis Picnic Day and future Picnic Days. Doctoral student and medical entomologist Olivia Winokur of the Chris Barker lab, serves as treasurer of EGSA and t-shirt sales coordinator. She may be reached for more information at email@example.com.
The EGSA is comprised of UC Davis graduate students who study insect systems. Its objectives are to connect students from across disciplines, inform students of and provide opportunities for academic success, and to serve as a bridge between the students and administration. The officers, in addition to Brendon Boudinot, are Emily Bick of the Christian Nansen lab, vice president; Maureen Page of the Neal Williams lab, secretary; Olivia Winokur of the Chris Barker lab, treasurer; and two Graduate Student Association representatives, Charlotte Herbert of the Bohart Museum of Entomology and Nick Booster of the Jay Rosenheim lab.
Sarah Silverman, a doctoral candidate who is studying insect demography at UC Davis with major professor James R. Carey, won a second-place award in her category.
Boudinot, who studies classification and evolution of morphology, delivered a 10-minute oral presentation in the Systematics, Evolution and Biodiversity Section on "The Protopodal Theory of Genitalic Evolution in the Hexapoda (Arthropoda: Mandibulata: Pancrustacea)."
Boudinot completed his undergraduate work at the Evergreen State College, Olympia, Wash., and spent a year working as a research technician at the University of Utah before starting his graduate work in 2014 with advisor Phil Ward. He focuses his research on evolution and ecology, approached from the perspective of systematics. “I integrate several lines of inquiry to answer historical evolutionary questions, including morphological and molecular phylogenetics, paleontology, and traditional comparative morphology,” Boudinot related. “I specialize on the skeletomusculature system of the male genitalia of the Hexapoda and the classification of the Formicoidea.”
Silverman gave a 10-minute oral presentation in the Diptera-Mosquitoes category of the Medical, Urban, and Veterinary Entomology Section, on “Population as Cohort: Interpreting the Mortality Patterns of Wild-Caught Adult Mosquitoes of Unknown Ages.”
Silverman completed her bachelor's degree in environmental science at McGill University in Montreal. For her undergraduate thesis, she studied the phenology of wild Osmia bees. Her work at UC Davis is in the field of insect demography. “I specifically study insect lifespan in the wild, as well as the the age-structure of insect populations in the wild using an innovative methodological approach: the capture of live-insects in the wild which are then maintained and observed in the lab until death,” she said.
At its annual meetings, the ESA offers graduate students the opportunity to present their research and win coveted prizes. The first-place President's Prize recipient receives a one-year free membership in ESA, a $75 cash prize, and a certificate. The second-place winner receives a one-year free membership in ESA and a certificate.
The oral presentations are evaluated on scientific content (50 percent) and presentation (50 percent). For scientific content, judges score them on introduction and background with pertinent literature cited; objectives clearly stated and concise; materials and methods (study design) clear and concise; results and discussion clear, concise and accurate; and significance of results to field of study. Judges evaluation the presentation on organization, slides and delivery.
Boudinot's previous President's Prizes were for work on the male genitalia of ants, and for providing the first male-based identification material for the ant genera of the New World.
Ants are highly diverse, with over 13,000 known species, Boudinot said. "They are, however, but one stitch in the diversity of all insects, and we are entering a new era for the study of morphology in the 21st century."
The genitalia of male insects are fascinating, he said. "Both male and female insect genitalia are derived from the appendages of a pair of abdominal segments. Evidence from the skeletomusculature indicates that these structures are really legs of a crustacean ancestor that have been modified for numerous reproductive tasks--from copulation and insemination, to singing and silk-spinning."
The event, free and open to the public, takes place from noon to 1:30 p.m. in the half-acre bee garden, located on Bee Biology Road, next to the Harry H. Laidlaw Jr. Honey Bee Research Facility, west of the central campus.
Among the native ants at the haven are
- Dorymyrmex insanus (workers small, ~3 mm long, black; conspicuous crater-shaped nests in bare soil)
- Dorymyrmex bicolor (workers small, ~3 mm long, bicolored, dull orange and black; conspicuous crater-shaped nests in bare soil)
- Prenolepis imparis (also known as the “winter ant” or “winter honey ant”; workers small (3-4 mm long), brown, with shiny gaster; inconspicuous nests in soil)
- Formica moki (sometimes called “field ants”; workers medium-sized (6 mm long), with a dark head, orange-brown mesosoma (thorax) and silvery-gray gaster; nest in soil)
Images of these species can be found on the AntWeb (www.antweb.org).
The haven is home to many insects other than bees, noted Christine Casey, director of the Häagen-Dazs Honey Bee Haven, which is owned and operated by the UC Davis Department of Entomology and Nematology. It was planted in the fall of 2009.
Approximately six other species of native ants reside in the vicinity of the garden, including Formica aerata, Pogonomyrmex subdentatus, and Solenopsis xyloni. The introduced Argentine ant (Linepithema humile) occurs around the Bee Biology building, but it appears not to have colonized the bee garden.
Attendees will learn how to observe and identify California native ants, and learn about the differences between bees and ants.
John "Jack" Longino, professor and associate chair of biology at the University of Utah, Salt Lake City, and the adjunct curator of entomology, Utah Museum of Natural History, University of Utah, will speak on "Project ADMAC or Ant Diversity of the Mesoamerican Corridor" from 12:10 to 1 p.m. in 122 Briggs Hall.
Ant specialist Phil Ward, professor of entomology, UC Davis Department of Entomology and Nematology, will introduce and host him.
"The MesoAmerican corridor is a zone of complex tectonic history, episodic biotic interchange between large continents, and frequent mountain-building," Longino said. "Ants blanket this landscape, forming a tapestry of fine-scale habitat specialization and geographic replacement. Many taxonomists have contributed to the description of species in the region and this fundamental 'biodiversity mapping' continues apace. Project ADMAC (Ant Diversity of the MesoAmerican Corridor) combines morphological analysis with large-scale DNA sequencing (targeted enrichment of Ultra-Conserved Elements) to reveal the evolutionary history and geographic structure of ant species in MesoAmerica.
"Ants show very strong patterns of elevational specialization and geographic turnover, and Project ADMAC will address questions of (1) how and when montane species evolve, (2) the effects of differing mountain ages on communities, (3) the impact of lowland barriers on montane ant dispersal, and (4) whether ants experienced a major biotic interchange on the closure of the Panamanian isthmus."
Longino addressed the Entomological Society of America meeting last November on the topic. He told of plans
1. to build a detailed biodiversity map for an ecologically dominant group of insects (ants) in a biogeographically important region of the world (the MesoAmerican corridor);
Longino's fascination with insects began in his childhood. His research statement:
"We share the planet with millions of species, and many of them are insects. A childhood fascination with insects led me to an interest in ecology and the desire to explain patterns of diversity, and I settled on ants as an ecologically dominant group of insects worthy of study. As it became clear that I was living during a time of enormous biotic change caused by human activities, I developed a strong conviction that it was important not only to understand patterns of diversity but to document it in detail for this time in history. I divide my time between two research fields: taxonomy and ecology. On the taxonomy side, I have coordinated large-scale inventories of Neotropical insect biodiversity, I discover and describe new species of ants, and I further refine our understanding of species ranges and morphological variability. I make use of advanced imaging technology, specimen-level databases, and Web-dissemination to make biodiversity data available to the widest audiences. On the ecology side, I use quantitative inventory techniques that allow analysis of diversity patterns. I am interested in how species are distributed on tropical mountainsides, what ecological factors explain the elevational range limits of species, and how species might respond to climate change."
Longino was interviewed in August of 2013 by NPR on his research. He told NPR he started out collecting stamps in his childhood, but that bored him. He decided to "get small."
"If you're shopping for a home entertainment system," he says, "you can't do better than a good dissecting microscope," he said. At the time of the NPR interview, Longino had just published two papers describing 33 new species of ants, bringing his personal "new species" total to 131, NPR reported. In the article, Longino described himself as "average" among entomologists, pointing out that some entomologists have described thousands of new species.
Longino received his bachelor's degree in zoology, with distinction, in 1978 from Duke University, and his doctorate in zoology in 1984 from the University of Texas, Austin. He then served as an assistant research biologist at UC Santa Barbara; academic director of the Monteverde Tropical Biology Quarter, UC Education Abroad Program; adjunct assistant curator of the Florida State Museum of Natural History (Allyn Museum of Entomology), and scientific director of Project ALAS. He joined the Evergreen State College, Washington, serving from 1991 to 2011 before becoming a professor in the Department of Biology, University of Utah.
