Her major professor Jason Bond, then a professor and administrator at Auburn University, Alabama, described and named what is commonly called "The Barack Obama Trapdoor Spider" in 2012.
The article, published in the journal Ecology and Evolution and part of Newton's 2022 doctoral dissertation, is titled "Phylogeography and Cohesion Species Delimitation of California Endemic Trapdoor Spiders within the Aptostichus icenoglei Sibling Species Complex (Araneae: Mygalomorphae: Euctenizidae)."
Co-authors are Professor Bond, who is the Evert and Marion Schlinger Endowed Chair in the UC Davis Department of Entomology and Nematology, and associate dean, College of Agricultural and Environmental Sciences; and Bond lab members, project scientist James Starrett and doctoral candidate Emma Jochim.
"Species delimitation in mygalomorph spiders using only traditional morphological approaches has underestimated species diversity," Newton said, "yet molecular approaches have been shown to overestimate species diversity due to the local population structuring seen as 'species divergence.' Specifically, the Aptostichus icenoglei complex, which comprises the three sibling species, A. barackobamai, A. isabella, and A. icenoglei, exhibits evidence of cryptic mitochondrial DNA diversity throughout their ranges across the California Floristic Province."
The researchers sampled 62 individuals overall for the three species within the complex, using both specimens from Bond (2012) and new records. "A. barackobamai was collected across its geographic range in northern California for a total of 21 samples, and A. icenoglei was collected throughout its range in southern California for a total of 40 samples," they wrote. "Only one specimen of A. isabella was included in this study due to collecting constraints (i.e., only one individual of this species has ever been collected and a burrow has not yet been found containing this species; Bond, (2012)
Next steps? "We hope to use whole genomes for both reconstructing evolutionary relationships as well as identifying genes that contribute to potential adaptive divergence across the landscape," Newton said. "We also hope to gather more natural history data for each of the species, especially A. icenoglei populations, for general ecological information that may aid in species delimitation."
Born and raised in Eupora, Miss., and a first-generation college student in her family, Lacie holds a bachelor of science degree in biological sciences (2016) from Millsaps College, Jackson, Miss. She then enrolled in the graduate school program at Auburn University, studying with Professor Bond. When he accepted the Schlinger Endowed Chair in 2018, Lacie, along with other lab members, transferred to UC Davis. Newton completed her dissertation on species delimitation in two trapdoor spider groups, Antrodiaetus unicolor complex and Aptostichus icenoglei sister species complex, and evaluation of interspecific relationships within the genus Aptostichus.
The research drew support from a National Science Foundation Grant awarded to Bond and Starrett; the McBeth Memorial Scholarship awarded to Newton; and the Evert and Marion Schlinger Foundation.

"Spiders placed in the infraorder Mygalomorphae (tarantulas, trapdoor spiders and their kin) are generally recognized as an ancient cosmopolitan lineage that has persisted for over 250 million years," Newton wrote in her abstract. "Mygalomorph life history traits that include limited dispersal abilities, habitat specialization, and site fidelity altogether make them ideal organisms for studying speciation pattern and process, phylogeography, and adaptation. Evolutionary studies of mygalomorphs at both shallow and deeper phylogenetic levels have been limited prior to the advent of next generation sequencing approaches, with the majority of such studies relying on morphological characters or limited targeted locus approaches for phylogenetic reconstruction. Thus, it is imperative to implement larger genomic-scale datasets for confident reconstruction of relationships."
Her dissertation focuses on species delimitation in two trapdoor spider groups, Antrodiaetus unicolor complex and Aptostichus icenoglei sister species complex, and evaluation of interspecific relationships within the genus Aptostichus. To address species boundaries in the A. unicolor species complex, she implemented genomic-scale data (that it, restriction-site associated DNA sequencing, RADseq) in conjunction with morphological, behavioral, and ecological data to evaluate cohesion species identity (Chapter I).
Similarly, assessing species boundaries in the Aptostichus icenoglei sibling species complex involved a target capture approach for subgenomic data (that is, ultraconserved elements, UCEs) and ecological data to evaluate genetic and ecological exchangeability, as per the cohesion species-based delimitation approach from a previous study (Chapter II).
Newton expects to receive her doctorate by the end of summer and "then I will be heading to the American Museum of Natural History where I will be working in Jessica Ware's lab as a postdoctoral fellow on systematics of broader Odonata as well as Anisoptera (dragonflies)."
First-Generation College Student. Born and raised in Eupora, Miss., Lacie is a first-generation college student. She received her bachelor of science degree in biological sciences from Millsaps College in 2016 and then enrolled in the graduate school program at Auburn University, Alabama, studying with Professor Bond. When he accepted the Schlinger Endowed Chair in Insect Systematics in 2018, Lacie, along with other lab members, transferred to UC Davis.
What sparked her interest in spiders? “I actually used to be terrified of spiders,” Lacie acknowledged. “It wasn't until fall semester of my sophomore year when I took a zoology course that I began to appreciate not only the vast amount of diversity within spiders but also how amazing they are as a group, such as the tensile strength of spider silk being comparable to steel, spider venoms playing a role in potential medical applications, and a myriad of feeding strategies, etc..”
Her research on folding-door spiders or the Antrodiaetus unicolor species complex led to a journal article published in Molecular Ecology: “Integrative Species Delimitation Reveals Cryptic Diversity in the Southern Appalachian Antrodiaetus unicolor (Araneae: Antrodiaetidae) Species Complex.” UC Davis co-authors are Professor Bond, who is the Evert and Marion Schlinger Endowed Chair in Insect Systematics, and project scientist James Starrett of the Bond lab.
Newton is active in both the American Arachnological Society (AAS) and the Society of Systematic Biologists. She won a second-place award for her oral presentation on species delimitation at the 2019 AAS meeting, held at Washington and Lee University, Lexington, Va.
At UC Davis, Newton served as a teaching assistant for the “Introduction to Biology: Biodiversity and the Tree of Life” course. Her resume also includes:
- mentoring undergraduate students in the Mentoring Program, Equity in Science, Technology, Engineering, Math, and Entrepreneurship (ESTEME) organization, a graduate student organization dedicated to improving equity and inclusion in STEM fields, entrepreneurship, and leadership positions.
- volunteering on the admissions committee for GOALS, the Girls' Outdoor Adventure in Leadership and Science, a summer science program for high school students to learn science hands-on while backpacking through the wilderness.
AAS Conference at UC Davis. Newton is looking forward to the AAS conference, set June 26-30, at UC Davis, and will be assisting at the Eight-Legged Encounters open house from 1 to 4 p.m., June 25 at the Bohart Museum of Entomology, located in Room 1124 of the Academic Surge Building on Crocker Lane. The event will officially kick off the AAS meeting.
A "powerhouse" of arachnologists will be participating, said Bond, who will be hosting the conference with Lisa Chamberland, postdoctoral research associate, Department of Entomology and Nematology, and Joel Ledford, assistant professor of teaching, Department of Plant Biology, College of Biological Sciences.
Professor Eileen Hebets of the School of Biological Sciences, University of Nebraska, Lincoln, is co-hosting the open house as part of a U.S. National Science Foundation grant, “Eight-Legged Encounters” that she developed as an outreach project to connect arachnologists with communities, especially youth.
Some 20 exhibits and activities will be set up in the hallway of the Academic Surge Building, said Tabatha Yang, the Bohart Museum's education and outreach coordinator. “There will be everything--spider specimens, live arachnids, activities, artwork, etc.," Bond related.

On her Aedes aegypti poster:
Research in our lab has identified significant variability in the resistance phenotype of mosquitoes with target-site mutations, prompting us to wonder about the metabolic mechanisms involved in resistance in California populations of Aedes aegypti. The resistance phenotype is thought to have multiple fitness costs, including reduced fecundity, adult body size and longevity (6–9). We hypothesize that looking at the insect's metabolome may allow us to better understand the physiology behind these potential fitness costs by providing a snap shot of the insect's metabolite composition and insight into pathway demands and energetic deficiencies. Metabolomics has the benefit of providing insight into mosquito biology at the level of phenotype.

The abstract:
Most of tomato production in California occurs in the Central Valley, which has “the foothills” as its western boundary. Beet leafhoppers overwinter in green natural vegetation in the foothills and migrate into crop fields, including tomato, during spring as natural vegetation dries out and green crop vegetation becomes available. In this study, we built a simulation model predicting spring migration of beet leafhoppers based on vegetation greenness in the foothills. Vegetation greenness (EVI, Enhanced vegetation index) in the foothills was calculated based on analyses of satellite imagery. Spring migration of s was monitored at three different locations in the foothills for two years using yellow sticky cards. Spring migration of beet leafhoppers was well described by the Weibull function. At all monitoring locations, the spring migration was started when the EVI values dropped to 0.2, and the proportion of migrating beet leafhoppers rapidly increased as the EVI values decreased. Our study indicates that the decrease in vegetation greenness triggers spring migration of beet leafhoppers and shows great potential for developing an early warning system.

Why Do Museum Collections Matter?
"Cabinets of curiosity” and natural history museums are the original basis of our knowledge of global biodiversity. Such collections, however, are more than just well-organized dead organisms. Museums are enormous libraries of identified species, localities, and dates, constantly updated and reorganized based on the best new information. These data inform countless fields of research, and can even answer future questions no one has yet thought to ask. Most importantly, they preserve irreplaceable type specimens, which are a crucial part of species description. Now that many of these insect collections are being digitized and accessed from around the globe, why is it necessary to maintain them as physical materials? While many datasets do lend themselves well to digitization, insect specimens experience significant data loss. Most commonly, photographs are taken of the specimens, but photos are usually inadequate for discerning taxonomic features. Even high-resolution 3D scans are no substitute for direct observations. Finally, museums are centers of education and public outreach. Through collections, biology students and communities can physically experience global insect biodiversity they might not otherwise see, regardless of location or mobility. The “wow” factor of magnificent specimens is most powerful in person. As our lives become increasingly computer-oriented, we must recognize that to enjoy and study nature, no digital replacement will suffice.
Lacie Newton of the Jason Bond lab, expects to obtain her doctorate in entomology in June 2022. She holds a bachelor of science degree in biological sciences (2016) from Millsaps College, Jackson, Miss.
The Abstract:
Although species delimitation can be highly contentious, the development of reliable methods to accurately ascertain species boundaries is an imperative step in cataloguing and describing Earth's quickly disappearing biodiversity. Spider species delimitation remains largely based on morphological characters; however, many mygalomorph spider populations are morphologically indistinguishable from each other yet have considerable molecular divergence. The focus of our study, the Antrodiaetus unicolor species complex containing two sympatric species, exhibits this pattern of relative morphological stasis with considerable genetic divergence across its distribution. A past study using two molecular markers, COI and 28S, revealed that A. unicolor is paraphyletic with respect to A. microunicolor. To better investigate species boundaries in the complex, we implement the cohesion species concept and use multiple lines of evidence for testing genetic exchangeability and ecological interchangeability. Our integrative approach includes extensively sampling homologous loci across the genome using a RADseq approach (3RAD), assessing population structure across their geographic range using multiple genetic clustering analyses that include structure, principal components analysis and a recently developed unsupervised machine learning approach (Variational Autoencoder). We evaluate ecological similarity by using large‐scale ecological data for niche‐based distribution modelling. Based on our analyses, we conclude that this complex has at least one additional species as well as confirm species delimitations based on previous less comprehensive approaches. Our study demonstrates the efficacy of genomic‐scale data for recognizing cryptic species, suggesting that species delimitation with one data type may underestimate true species diversity in morphologically homogenous taxa with low vagility.

The Abstract:
Bees encounter pesticides across landscapes as they forage for pollen and nectar. Exposure to pesticides has negative effects on wild bees, but little is known about the effects of chronic larval exposure on adult performance. We investigated the effects of larval and adult pesticide exposure on the foraging and reproduction of the solitary bee, Osmia lignaria. We established nesting O. lignaria females in 16 field cages containing wildflowers treated with or without imidacloprid, the most widely used neonicotinoid insecticide. As larvae, these parent bees were reared on provisions containing imidacloprid or controls. Larval and adult pesticide exposure directly affected bee nesting activity. Bees exposed to pesticides as adults were less likely to start nesting and produced fewer offspring. Additionally, bees exposed to pesticides as larvae provisioned fewer offspring than unexposed controls. Our research provides experimental evidence of the effects of pesticide exposure on solitary bees across multiple life stages, a critical step in understanding mechanisms underlying pollinator health.

The question is crucial “because it is the foundation of essentially all biological questions,” says spider systematics researcher Lacie Newton, a doctoral student in the Jason Bond laboratory, UC Davis Department of Entomology and Nematology, and the lead author of newly published research that explores that question.
“For example,” Newton says, “making successful conservation efforts depends on knowing how to identify the threatened/endangered species from other closely related species that are not threatened.”
Her research on folding-door spiders or the Antrodiaetus unicolor species complex led to a journal article published in Molecular Ecology: “Integrative Species Delimitation Reveals Cryptic Diversity in the Southern Appalachian Antrodiaetus unicolor (Araneae: Antrodiaetidae) Species Complex.” UC Davis co-authors are Professor Bond, who is the Evert and Marion Schlinger Endowed Chair in Insect Systematics, and project scientist James Starrett of the Bond lab.
Folding-door spiders are so named because they close the entrances to their silk-lined burrows by pulling in the rim. They are often described as having stocky brown bodies, thick legs and large fangs.
The five-member research team, also including Professor Brent Hendrixson of Millsaps College, Jackson, Miss., and postdoctoral fellow Shahan Derkarabetian of Harvard University, used an integrative approach with several lines of evidence (morphological, behavioral, molecular, and ecological data) to form a consensus “about where we should draw the lines between species in this complex,” Newton said.
They targeted the Antrodiaetus unicolor species complex, which Newton said, are “great organisms for exploring species boundaries because even though these spiders do not have any obvious visual differences to tell them apart--with the exception of the smaller and lighter brown A. microunicolor-- there are significant genetic differences between certain populations, that is potential 'cryptic' species.”
Said Professor Bond of the journal article: “I think its significance lies in the innovative and multipronged approach (integrative) she employed to evaluating species boundaries. The study emphasizes the importance of using both genomic scale and ecological data rather than relying on traditional morphological features alone to delimit species. Understanding species boundaries is an imperative for cataloging and describing the planet's rapidly disappearing biodiversity.”
Newton won a second-place award for her oral presentation on species delimitation at the 2019 American Arachnological Society (AAS), held at Washington and Lee University, Lexington, Va. Her abstract: “Although species delimitation can be highly contentious, the development of reliable methods to accurately ascertain species boundaries is a fundamental and necessary step in cataloguing and describing Earth's quickly disappearing biodiversity. Species delimitation in spider taxa has historically been based on morphological characters; however, certain mygalomorphs are morphologically indistinguishable from each other yet have considerable molecular divergence." She is active in both AAS and the Society of Systematic Biologists.
First-Generation College Student
Newton, a first-generation college student, is a fifth-year doctoral program student whose research interests include systematics, Araneae, mygalomorph spiders, speciation pattern and process, phylogeography, molecular phylogenetics, and character evolution. She is the recipient of a year-long UC Davis Graduate Research Mentorship Fellowship that supports promising doctoral students that meet diversity criteria.
Born and raised in Eupora, Miss.-- “a very small town with less than 2000 people”--Lacie recalls a childhood that included “a significant amount of time outdoors with my family surrounded by the rich flora and fauna of the Coastal Plain Floristic Province.”
“This experience,” she related, “fostered my interest in biodiversity and later guided me to take additional science classes to learn more about the complexities of the living world.”
What sparked her interest in spiders? “I actually used to be terrified of spiders,” Lacie acknowledged. “It wasn't until fall semester of my sophomore year when I took a zoology course that I began to appreciate not only the vast amount of diversity within spiders but also how amazing they are as a group, such as the tensile strength of spider silk being comparable to steel, spider venoms playing a role in potential medical applications, and a myriad of feeding strategies, etc..”
“As my professor Dr. Brent Hendrixson shared his research interests (systematics of mygalomorph spiders and scorpions) and passion for scientific outreach, I evolved from a guarded student to a fascinated one. Additional summer field courses focused on the biology, evolution, and ecology of arachnids completely changed my career trajectory from becoming a medical doctor to an evolutionary biology professor with research emphasizing evolutionary processes of arachnid study systems, specifically mygalomorph spiders like Antrodiaetus.”
Career as Evolutionary Biologist
The UC Davis doctoral student plans a career as an evolutionary biologist, exploring the evolutionary history of mygalomorph spiders. “My ultimate career goal is to become a biology professor where I can perform research and teach in a vibrant academic setting,” Newton said. “As a professor, my aims are to become an expert in my desired field of evolutionary biology, continue to be involved in the scientific community through collaborations with researchers, and become an advocate for vision and change in science education. “
“To clarify,” she added, “I want to study the evolutionary history of arachnids by using emerging technologies/methods and bioinformatics tools. I also plan to participate in the scientific community by publishing articles in respected journals, attending and presenting at conferences, and collaborating with various researchers. Lastly, I plan to take part in teaching and outreach opportunities to convey my enthusiasm for science to others. I feel outreach is especially important to get children enthusiastic about science and to demystify science for the public.”
Newton aims to become a faculty mentor “who can positively impact students--the way my own undergraduate mentor Dr. Hendrixson affected my life--by using my position as a professor to extend opportunities to mentor high school students, undergraduate students, and graduate students, especially from underrepresented groups such as women and members of the LGBTQ community. Specifically, I want to mentor students about career options available as well as offer my own point-of-view about pursuing a career in a STEM field.”
At UC Davis, Newton served as a teaching assistant for the “Introduction to Biology: Biodiversity and the Tree of Life” course. She is mentor to undergraduate students in the Mentoring Program, Equity in Science, Technology, Engineering, Math, and Entrepreneurship (ESTEME) organization, a graduate student organization dedicated to improving equity and inclusion in STEM fields, entrepreneurship, and leadership positions. She also volunteers on the admissions committee for GOALS, the Girls' Outdoor Adventure in Leadership and Science, a summer science program for high school students to learn science hands-on while backpacking through the wilderness.
In addition, Newton volunteers at the annual UC Davis Biodiversity Museum Day and at the Bohart Museum of Entomology open houses, including one featuring “Eight-Legged Wonders (Spiders).”
The "eight-legged wonders," as she said, fascinate her. It's "not only the vast amount of diversity within spiders but also how amazing they are as a group."
