She studies with major professor Jason Bond, the Evert and Marion Schlinger Endowed Chair in Insect Systematics in the UC Davis Department of Entomology and Nematology.
Godwin delivered her presentation—her first ever at an ESA meeting--on “Phylogeny of a Cosmopolitan Family of Morphologically Conserved Trapdoor Spiders (Mygalomorphae, Ctenizidae) Using Anchored Hybrid Enrichment, with a Description of the Family Halonoproctidae Pocock 1901.”
Godwin competed against nine other presenters in her category, "Graduate Student 10-Minute Presentations: Phylogenetics" (within the ESA Systematics, Evolution and Biodiversity Section).
As a prize winner, she received a year's membership to ESA and a certificate. Overall, the ESA program drew 265 scientific sessions featuring 2,430 oral and 569 poster presentations with presenters from 68 different countries, according to Joe Rominiecki, ESA manager of communications. The submissions in the student competitions totaled 773, he said, adding “A student may enter both the Student 3-Minute Presentation Competition and the Student Poster Competition.”
Godwin's dissertation research deals generally with trapdoor spiders in the family Ctenizidae. “These spiders are distributed across the globe, on every continent but Antarctica,” she noted. “They create silk-lined burrows with cryptic trap doors in which they spend their entire lives. Broadly, I am studying the evolutionary history and phylogenetic relationships among the members of the Ctenizidae, and describing a large amount of previously undocumented diversity along the way. Specifically, my dissertation addresses the monophyly of the family, phylogeography of two genera, Hebestatis and Bothriocyrtum, which occur in the California Floristic Province, and a revision of the genus Ummidia in North and South America.”
The abstract of her ESA presentation:
“The mygalomorph family Ctenizidae previously had a world-wide distribution and contained nine genera and 135 species. However, the monophyly of this group had long been questioned on both morphological and molecular grounds. We use Anchored Hybrid Enrichment (AHE) to gather hundreds of loci from across the genome for reconstructing the phylogenetic relationships among the nine genera and test the monophyly of the family. We also reconstruct the possible ancestral ranges of the most inclusive clade recovered.”
“Using AHE, we generate a supermatrix of 565 loci and 115,209 bp for 27 individuals. For the first time, analyses using all nine genera produce results definitively establishing the non-monophyly of Ctenizidae. A lineage formed exclusively by representatives of South African Stasimopus was placed as the sister group to the remaining taxa in the tree, and the Mediterranean Cteniza and Cyrtocarenum were recovered with high support as sister to exemplars of Euctenizidae, Migidae, and Idiopidae. All the remaining genera—Bothriocyrtum, Conothele, Cyclocosmia, Hebestatis, Latouchia, and Ummidia—share a common ancestor. Based on these results, we elevated this clade to the level of family. Our results definitively establish both the non-monophyly of the Ctenizidae and non-validity of the subfamilies Ummidiinae and Ctenizinae. We formally described the family Halonoproctidae Pocock 1901 and infer that the family's most recent common ancestor was likely distributed in western North America and Asia.”
Godwin holds a bachelor of science degree in zoology (2004) and a master's degree in wetland biology (2011) from Auburn (Ala.) University. She joined the doctoral program at Auburn University in 2016 and transferred to UC Davis this year, joining her major professor Jason Bond, a seven-year Auburn faculty member who chaired the Department of Biological Sciences, and curated arachnids and myriapods at the Auburn University Museum of Natural History.
Godwin will be among those participating in the Bohart Museum of Entomology's open house on "Eight-Legged Wonders" on Saturday, March 9, from 1 to 4 p.m. The Bohart is located in Room 1124 of the Academic Surge Building on Crocker Lane. She was featured in a recent article in the Savannah Morning News, Georgia, on trapdoor spiders.
She delivered her presentation on “Phylogenetic Relationships of Spider Flies (Acroceridae) – Discordance, Uncertainty and the Perils of Phylogenomics.” Acrocerid adults are floral visitors, and some are specialized pollinators, while the larvae are internal parasitoids of spiders.
Approximately 350 delegates attended the conference; the scientists focus on the Diptera order, which includes houseflies, mosquitoes, and gnats. Gillung was among 40 students presenting their research.
Gillung studies with major professor Lynn Kimsey, director of the Bohart Museum of Entomology and professor of entomology, UC Davis Department of Entomology and Nematology; mentor Shaun Winterton of the California Department of Food and Agriculture; and collaborator Phil Ward, UC Davis professor of entomology.
UC Davis doctoral students Charlotte Herbert Alberts and Socrates Letana, who both study with Kimsey, also presented their work; Alberts delivered an oral presentation on her research (she studies Asilidae (Assassin flies), and Letana displayed a poster on bot flies.
Presenting the award to Gillung was Professor Thomas Pape of the Natural History Museum of Denmark and chair of the Council for the International Congresses of Dipterology, which organizes the conferences. The next Congress takes place in 2022 in California.
In her abstract, Gillung described spider flies “as a monophyletic group of lower Brachycera currently classified into three subfamilies, 55 genera and ca 530 species.”
“The group has long been considered a rogue taxon and its placement within the Diptera tree of life remains uncertain,” she wrote. “Phylogenetic relationships among lineages of spider flies are by contrast relatively well established, with hypotheses proposed based on molecular data from both Sanger and high-throughput sequencing. Phylogenomic estimation of spider fly relationships yields different topologies, depending on whether data is coded and analyzed as nucleotides or as amino acids. The most significant difference among the two data types is in the monophyly of Panopinae; a morphologically and ecologically recognizable group, that is recovered as monophyletic only in the analyses of nucleotides. This study uses Acroceridae as a system to explore the effects of potential confounding factors in phylogenomic reconstruction. This research takes advantage of modern and powerful statistical approaches, including posterior predictive simulation, to understand the effects of conflict, uncertainty and systematic error in the estimation of evolutionary relationships using the standard phylogenomic toolkit.”
Gillung, to receive her doctorate this month, will present her exit seminar on “Evolution of Fossil and Living Spider Flies (Diptera, Acroceridae): A Tale of Conflict and Uncertainty” at 2 p.m., Friday, Dec. 14 in 122 Briggs Hall.
"Parasitoid flies," Gillung wrote in her abstract for her Dec. 14 seminar, "are some of the most remarkable, yet poorly known groups of insects. Represented by over 10,000 species distributed in 21 families, dipteran parasitoids comprise over 100 independent lineages, offering an unparalleled system to understanding the origin, evolution and diversification of the parasitoid life history. My dissertation research unraveled the systematics, evolution and biology of a lineage of dipteran parasitoids specialized in spiders, Acroceridae, commonly known as spider flies. My research resulted in a monograph of fossil spider flies, and a robust hypothesis for the pattern and timing of spider fly evolution based on high throughput sequencing. Through the combination of DNA sequence data obtained via Sanger sequencing with morphological characters, I also estimated their relationships among spider fly genera using an extensive taxon sampling which culminated in a new taxonomic classification for the family.”
Gillung has accepted a postdoctoral position at Cornell University, Ithaca, beginning Jan. 2. She will be working with Bryan Danforth on Apoidea (stinging wasps and bees) phylogenomics, evolution and diversification.
She recently was named the recipient of the prestigious 2018 Student Leadership Award, presented by the Pacific Branch, Entomological Society of America (PBESA), which represents 11 states, seven U.S. territories, and parts of Canada and Mexico.
A native of Brazil, Jessica holds a bachelor's degree in biology from the Federal University of Paraná, Curitiba, Brazil and a master's degree in zoology from the University of São Paulo, Brazil. She speaks four languages fluently: Portuguese, Spanish, English and German.
The conference, themed “Multidimensional Solutions to Current and Future Threats to Pollinator Health,” will cover a wide range of topics in pollinator research: from genomics to ecology and their application to land use and management; to breeding of managed bees; and to monitoring of global pollinator populations. Topics discussed will include recent research advances in the biology and health of pollinators, and their policy implications.
