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.

Insect species distributions are tightly linked to winter conditions. Surviving winter requires adaptations to cope with low temperatures and limited food resources, and much of our lab’s work focuses on the underlying mechanisms used by insects to survive extreme winter conditions. In this talk, I will primarily discuss our recent work on survival mechanisms of the Antarctic midge, which is the world’s southernmost insect and the only species endemic to Antarctica. This species can survive freezing of its body fluids for up to nine months a year, but it must also cope with considerable spatial and temporal variability in Antarctica’s unpredictable environments. Here, I will summarize how this impressive beast survives internal freezing, as well as the consequences of microhabitat variability and winter climate warming.

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.
