Dr. Tesla Monson | Monson Lab

BIO:

Dr. Tesla Monson is an Assistant Professor of Anthropology at Western Washington University where she runs the Primate Evolution Lab. Her lab’s research focuses on the evolution of skeletal variation, life history, and reproduction in extant and fossil mammals. Dr. Monson recently published the first methods for reconstructing prenatal growth rates in the fossil record, one of which relies exclusively on teeth. Dr. Monson earned her PhD in Integrative Biology at UC Berkeley (2017), which is where she first became interested in science communication and research. Since then, she has developed and hosted a series of sci-comm projects, ranging from a science talk radio program called The Graduates, to a Twitter series highlighting the influence of women in early Washington State history (Washington Women).

Abstract:

The vertebrate fossil record is comprised almost entirely of the remains of bones and teeth. It is thus a key goal for evolutionary biologists to extract as much information as possible from these anatomical remains through morphological investigation. My research has demonstrated that there are significant phenotypic correlations between many anatomical traits, as well as between craniodental morphology and life history. These correlations both constrain and enable evolution, leading to the morphological diversity and disparity that we see today. In this talk, I will discuss our new research using cranial and dental morphology to reconstruct prenatal growth rates in

the hominid fossil record. Prenatal growth, or how quickly a fetus grows in utero, varies widely across primate species with the highest rate in humans. We recently demonstrated that prenatal growth rates increased throughout the Pleistocene, reaching ‘human-like’ rates just under 1 million years ago, before the evolution of our species. Prenatal growth is also key to healthy pregnancy and delivery. I will end by presenting some of our ongoing and future research investigating prenatal growth, and the evolution of encephalization and body size in primates.

Hugo Reyes-Centeno HEVA (Human Evolution & Virtual Anthropology Lab) EduceLab

Dr. Hugo Reyes-Centeno is an evolutionary anthropologist specializing on the emergence of modern human anatomy and behavior over the last million years. In addition, he conducts inter-disciplinary research on human biocultural diversity and the study of natural and cultural heritage worldwide. Prior to joining the University of Kentucky in 2020 as Assistant Professor of Anthropology, he served as Scientific Coordinator and co-founder of the Center for Advanced Studies “Words, Bones, Genes, Tools” at the University of Tübingen (Germany), where he also completed a dissertation in the Institute of Archaeological Science and the Senckenberg Centre for Human Evolution and Paleoenvironments. His research has appeared in Cell, PNAS, Journal of Human Evolution, and PLoS Genetics, among other venues. He has performed paleontological and archaeological fieldwork in France, Italy, Peru, the Philippines, and Spain. Currently, he serves as Co-PI of the NSF-funded EduceLab: Infrastructure for Next Generation Heritage Science.

Abstract: Despite consensus on the emergence of anatomically modern humans in Africa and their subsequent dispersal into the rest of the world, the mode and timing of these processes remain controversial topics. In addressing them, data on human anatomical and genomic variation have sometimes generated conflicting inferences. Therefore, approaches that consider both lines of evidence under a common theoretical framework are important for reconciling competing evolutionary models. In this talk, I highlight research that tests competing models of human dispersal out of Africa, which applies quantitative genetic and population genetic methods to anatomical and genomic data. I discuss the caveats of these conclusions, including the influence of admixture between modern humans and other hominins. Furthermore, I examine how these findings align with the known human fossil record and a growing inventory of ancient genomes from archaeological and paleontological contexts. Finally, I review how ongoing field and laboratory projects in Eastern Africa, Southeast Asia, and South America shed light on human evolution, adaptations, and dispersals.

Christopher Schell ESPM Christopher Schell UC Berkeley

Bio:

Dr. Chris Schell is an Assistant Professor in the department of Environmental Science, Policy, and Management at the University of California Berkeley. Dr. Schell’s research focuses on the behavior, physiology, and health of wildlife in cities. Specifically, he and his lab investigate how urban infrastructure, environmental stressors, and human-wildlife interactions shape the phenotypic traits of mammalian carnivores, mainly coyotes and raccoons. Because the distribution of such attributes is often governed by societal inequities (e.g., socioeconomic, racial, etc.), Schell and his team also spotlight the need to incorporate an environmental justice and One Health lens into urban ecological research. Further, he is committed to community engagement and science communication, collaborating with organizations like the Cal Academy of Sciences, Oakland Zoo, East Bay Regional Parks, Doris Duke Scholars Conservation Program, and California’s 30x30 initiatives.

Abstract:

Past ecological processes and phenomena often have broad implications for contemporary habitat conditions and ecosystem structure. Long-term ecological research, for instance, has provided extraordinary insight into the processes that influence primary and secondary succession, population growth rates, community assemblages, and nutrient cycling. Similarly, past societal legacies have profound impacts on current societal processes, with much of our current reality shaped by policies enacted decades past. These social and ecological legacies are often most apparent in cities, where humans and their constructed ecosystems coalesce. It is in these environments that we have a unique opportunity to interrogate how our past shapes our social-ecological present. Necessarily, understanding how past societal processes have contributed to shaping current ecosystem processes is key to building predictive models and resilient systems for our future. In this talk, Dr. Chris Schell will explore how one of those legacies in particular – residential segregation via redlining – stratified people and resources, influencing myriad biophysical properties of the city that we currently experience. In doing so, he will discuss how urban evolutionary ecology research can serve to amplify how inequities in society drive ecological disparities in and outside of urban landscapes.

Abstract: A graduate student’s relationship with their research advisor is considered to be the single-most influential factor in the quality and outcomes of their graduate training experience. Indeed, effective mentorship by research advisors promotes the development and success of graduate mentees. Yet, mentoring relationships, like any prolonged relationship, can have negative elements. Little research has examined the problematic elements of graduate research mentoring, even though prior research on mentoring in workplace settings suggests that negative mentoring experiences are common. This seminar will present findings from research on the negative mentoring that graduate life science researchers experience, including how their experiences differ from negative mentoring experienced in workplace settings. The session will offer insights on how mentor behaviors may be experienced as harmful or unhelpful and on how mentees and mentors can identify, avoid, and mitigate the impacts of negative mentoring.

Evangeline Ballerini Ballerini Lab

Evangeline Ballerini is an Assistant Professor in Biological Sciences at California State University, Sacramento. Evangeline’s research examines the evolutionary genetics and developmental biology of traits influencing ecological interactions between plants and pollinators with a focus on the genus Aquilegia. Evangeline earned a BA from the Integrative Biology department at the University of California, Berkeley and a PhD from the Organismic and Evolutionary Biology department at Harvard University and conducted postdoctoral research at the University of Georgia and the University of California, Santa Barbara.

Abstract: The genus Aquilegia, commonly known as columbine, represents a classic example of adaptive radiation following the evolution of a key innovation - floral nectar spurs. Nectar spurs, tubular outgrowths of floral tissue that produce and store nectar, are hypothesized to promote speciation through pollinator specialization. Variation in spur morphology, along with other floral features such as color and orientation, allows flowers to adapt to different animal pollinators, contributing to reproductive isolation. I will present work focused on understanding the genetic basis of trait evolution in the genus Aquilegia at multiple evolutionary timescales. To shed light on how nectar spurs evolved in the Aquilegia ancestral lineage, I will highlight studies in which I used a combination of genomic and transcriptomic analyses to identify a key gene regulating nectar spur development. Focusing on more recent evolutionary history, I will discuss work in which I use similar techniques to explore the genetic basis of several floral traits distinguishing closely related Aquilegia species adapted to different animal pollinators and examine the population genetic processes influencing the evolution of these traits important for ecological speciation in the genus.
