Research Interests
Ecological Genetics is the study of how evolutionary forces (adaptation, migration, etc) shape the patterns of biodiversity observed in nature. My research focuses on restoring and managing plant populations to allow these natural processes to continue, even in presence of anthropogenic disturbances. Using a combination of molecular and quantitative techniques we try to better understand the level and distribution of genetic diversity within a species; in particular the role adaptation to local conditions as well as pollen and seed dispersal have played in creating these patterns. Currently my species of interest include Eriogonum spp. (America Buckwheat), Penstemon spp. (Beardtongues) and Cirsium spp. (Thistles).
- Seed transfer zone research on Penstemon and Eriogonum: Andrea Kramer (UIC Doctoral student) and I are using a combination of genetic and quantitative techniques to investigate ecosystem distinctiveness in two Great Basin genera, Eriogonum and Penstemon. We are using genetic markers to determine the distribution of genetic diversity and distance of gene flow between populations. In addition we are using a common garden trials to correlate differences in growth characteristics to growing conditions at their sites of origin; allowing us to work out which characteristics are important for restoration success. Mary Stupen (UIUC) is investigating more fine scale gene flow between and within mountain ranges of one of our study species, Eriogonum microthecum; for which we know little about its pollination biology.
- Importance of Pollinators in Great Basin communities: Working with Andrea Kramer (UIC Doctoral student) and Rebecca Tonietto we are investigating differences in pollinator communities on different mountain ranges in the Great Basin. Through a better understanding of how pollinators influence the plant communities that depend upon them for successful reproduction, we can help to ensure that restoration efforts not only reestablish plant communities, but all community level processes.
- Maternal Lines vs. Bulk Seed collection: Working with Andrea Kramer (UIC Doctoral student) and Jennifer Ison (UIC Doctoral student) will be investigating potential loses in genetic diversity through seed bulking practices, commonly used by restoration practitioners and breeders. Little empirical evidence is available on how much genetic diversity may be lost in the process, so the practice of bulking seed continues to be commonly employed.
- Pitcher's thistle (Cirsium pitcheri) research: Working with Kayri Havens, Pati Vitt and scientists at the Morton Arboretum and Chicago State University, on a long-term ecological research project are using more than 10 years genetic and demographic data to study "population persistence" by comparing long-term dynamics of natural and experimentally restored plant populations of Cirsium pitcheri (pitcher's thistle) a Federally listed Endangered species. One important concern with any restoration is problems arising from inbreeding. Using the common garden plants, Benjamin Staehlin (NU MS program) will be comparing fitness characteristics of small isolated and potentially inbred populations to that of a larger healthier population.
- Hill's thistle (Cirsium hillii) research: With the help of POC volunteers, we have been monitoring efforts and have shown that most populations in the Chicago area are overall relatively stable. Our genetic work has confirmed that both sexual and asexual reproduction has played an important role in the creation of most of these populations. We have found that Chicago Region populations of this species are unique and genetically diverse.
