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 award recognizes a graduate student for distinguished research and scholarly activity in the field of social insect biology. Borowiec received a certificate, honorarium, and a one-year subscription to Insectes Sociaux.
Borowiec is now a postdoctoral fellow in the lab of evolutionary biologist/ant specialist Christian Rabeling of Rochester, N.Y. The lab will be moving to Tempe, Ariz. in January.
“What is notable about Marek is that even as he became trained as a highly accomplished molecular phylogeneticist and computational biologist, he remained focused on organism-centered questions, driven by a deep and abiding appreciation of natural history,” said Ward.
Borowiec is the first from the Ward lab to receive the Eickwort Award.
The IUSSI-NAS Committee, chaired by Terry McGlynn and Stephen Pratt, and including members Rebecca Clark, Hongmei Li-Byarlay, Juliana Rangel, and Chris Smith, praised his work as having a significant impact on the field of social insect evolutionary biology.
They issued this statement:
“Although he has just received his PhD, Marek's work has already had a significant impact on the field of social insect evolutionary biology,” said the committee of . “His dissertation, completed under the supervision of Phil Ward at UC Davis, included a landmark revision of the genera in the diverse army ant subfamily Dorylinae. Marek produced a classification of the army ants in which morphological and molecular genetic data are fully congruent with each other, an unprecedented feat in ant taxonomy. His work showed decisively that the ‘army ant syndrome' evolved independently in the New World and Old World tropics, settling a century-old controversy.”
“Besides his army ant work, Marek also contributed to phylogenomic research demonstrating that ants are the sister group of the bees and spheciform wasps, and he was first author of an important paper showing that Ctenophora, the comb jellies, is the sister group to all other metazoans, thus resolving one of the earliest phylogenetic bifurcations in the animal kingdom. Marek's strengths in taxonomy and phylogenetics are supported by his accomplishments in bioinformatics, which include developing and publishing a novel tool to manipulate DNA sequence alignments of genomic datasets.”
“Marek's recommenders praise him as a well-rounded biologist with a deep appreciation of natural history. “He doesn't just excel in ant taxonomy, or phylogenetics, or bioinformatics. He excels in all of these disciplines. It is his love for ants and his curiosity about the natural world that motivates his studies.”
Marek is also a good scientific citizen, actively serving the systematics community as a subject editor for ZooKeys and Biodiversity Data Journal and as a frequent contributor to online systematics resources and databases. His research and scholarly achievements make Marek Borowiec a very deserving winner of this year's George C. Eickwort Student Research Award.”
Borowiec's research interests include phylogeny, taxonomy, biogeography, and natural history of ants. Before enrolling at UC Davis, Borowiec received his master's degree in 2009 from the Department of Biodiversity and Evolutionary Taxonomy, University of Wroclaw, Poland.
"My focus has been primarily on ant diversity and evolution and in my research I combine field work, morphology, molecular phylogenetics, and comparative methods," Borowiec said. "I am also interested in computing and phylogeny estimation from next-generation sequencing data."
This is his exit seminar. Borowiec received his doctorate in entomology in June, studying with major professor Phil Ward. He is now a postdoc in the lab of evolutionary biologist/ant specialist Christian Rabeling of Rochester, N.Y. The lab will be moving to Tempe, Ariz. in January.
"Ants are the world's most successful eusocial organisms." Borowiec says. "Long history, high species diversity, and extreme variety of life histories make them an excellent group in which many evolutionary questions can be addressed."

His dissertation research at UC Davis focused on building a taxonomic and phylogenetic framework for the research on army ant evolution. "Although army ants include very charismatic species, they belong to a larger group, the subfamily Dorylinae," he noted. "In addition to the army ants, dorylines comprise many cryptic ants whose biology and even taxonomy have been neglected. Partly as a result of this, even phylogenetic relationships of the army ants are not well-understood. The first step to advancing evolutionary research in the group was thus to examine the morphological diversity within this lineage. This resulted in a generic revision of the subfamily, published open-access in ZooKeys. Expertise gained during this work allowed me to design robust taxon sampling for a phylogeny of the dorylines based on next-generation sequencing data (ultraconserved elements or UCEs), currently in preparation."
Faculty and graduate students with the UC Davis Department of Entomology and Nematology--and others associated with an ENT/NEM lab--got together for a retreat, held Friday, Oct. 14 through Sunday, Oct. 16 at Sagehen Creek Field Station in Truckee.
Doctoral candidate (and photographer) Sandy Olkowski shared some of her photos of the activities, including insect collecting and dinner preparation. She also took a photo of deer at the campsite.
The participants got to know one another and also enjoyed the natural areas around the field station.
Sagehen Creek Field Station in Truckee is approximately 2 hours from Davis. It also the site of Professor Phil Ward's popular "Bug Boot Camp."
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.
