Restoration Genetics: Choosing "genetically appropriate material" for restoration has become an important aim of many restorations. I study the genetic, demographic, and community factors that might influence restoration success in a number of species:

  • Chris Woolridge is working with Andrea Kramer and I, looking at the impact of predictive provenancing (particularly collecting seed from more southerly populations) will have on extand populations
  • Golden paintbrush (Castilleja levisecta) — Restorations of golden paintbrush populations are ongoing in both Washington and Oregon. Adrienne Basey (MS Current), Andrea Kramer and I are working with Tom Kaye (Institute of Applied Ecology) and Peter Dunwiddie (University of Washington), looking into genetic changes that occur when a rare plant is brought into production for restoration purposes.
  • Castilleja affinis subsp neglecta - Is a rare endemic of Serpentine soils in the Bay Area. Laney Widener (MS current) has been investigating genetic variation within this species to guide restoration efforts. We are also working with David Tank at University of Idaho to compare this rare taxa within other similar california coastal Castilleja sp, using a combiantion of genomic, microsatellte and morphlogical techniques.
  • Wooly milkweed (Asclepias lanuginosa)—Genetic work by Eun Sun Kim (University of Illinois, Chicago, Ph.D, student) has established that clonal growth is limiting reproduction in this rare species and restoration is now being installed to see if we can improve sexual reproduction in this species.
  • Pitcher's thistle (Cirsium pitcheri)—Kayri HavensPati Vitt, and I have compiled more than ten years of genetic data in restored and native populations of Cirsium pitcheri, a federally listed endangered species.
  • Hill's thistle (Cirsium hillii)Abigail White is working with Andrea Kramer and I looking a restoration potential in this species. We are working with the Plants of Concern program, who have been monitoring populations in the Chicago area for more than ten years. We have established new genetically diverse restorations that are monitoring their success.
  • Lepidospartum burgessii -  Evelyn Webb Williams and I are working with Mike Howard (BLM - New Mexico) to identify if there are any potential genetic issues that might be limiting seed set. 

 

Genetics and Pollinators: The success and diversity of flowering plants is attributed in part to animal pollination. The genetic contribution of different pollinator guilds will vary through maternal fitness (number of seed sired), paternal fitness (number of fathers and distance of fathers) and connectivity between isolated populations. I am interested in the role pollinators play in driving the genetic structure of plant populations.

  • The shift from bee to bird pollination—Anna Braum (MS 2014) and Eun Sun Kim (University of Illinois, Chicago, Ph.D, student) has been investigating the underlying mechanisms that drive floral color polymorphism in Castilleja coccinea, a local paintbrush species whose populations are either completely red or yellow. 
  • The shift from bird to Hawkmoth pollination — Katie Wenzell (PhD Current) is work with Krissa Skogen and I looking at the role hawkmoth, bird and bee pollinations in Castilleja sessiliflora and it role in shaping floral morphology
  • Krissa Skogen, Norm Wickett, Rick Overson and Tania Jogesh are working on large project investigating Diversification in the Onagraceae Family, using Genomic, Population genetics and field data.
  • Paternity and Pollen Quality — Together with Krissa Skogen, Matt Rhodes (MS 2014) and Kathleen Kay (University of California, Santa Cruz), we are using exclusion experiments to compare the genetic differences in pollen quality of provided by different guilds of pollinators in Oenothera harringtonii and Clarkia breweri
  • Anita Cistenas-Fuentes is looking at the relationship between pollinators and rates of inbreeding, and the potential role this can have in the expression of inbreeding depression.

 

Hybridization: Working with a number of collaborators, we are investigating the potential threat of hybridization to populations of rare species, including Lantana depressa in Florida (Joyce Maschinski) and Lespedeza leptostachya in Minnesota (Alona Banai MS 2008), as well as the role hybridization might be playing in Phragmites australis invasion in the Chicago area (Dan Larkin)

Scent, Pollinators, Predators, and Floral Diversity in Evening Primrose group
Onagraceae, particularly species in tribe Onagreae, produce a floral scent that drives the biological interactions that impact plant fitness (fruit and seed production), including attracting legitimate pollinators (hawkmoths, bees) as well as floral and seed predators (Mompha moths). This scent, in turn, is used by these species to locate host plants to lay their eggs, which thereby impacts their reproductive fitness. Krissa Skogen, Norman Wickett, and I will be integrating chemical ecology and comparative genomics to explore the impact of past selective pressures on current patterns of diversity in these nonmodel organisms: evening primroses, hawkmoths, and micromoths. This is part of a National Science Foundation-funded Dimensions in Biodiversity grant —“Landscapes of Linalool: Scent-Mediated Diversification of Flowers and Moths across Western North America” — which is working in collabortation with other scientists at Agriculture & Agri-Food Canada, Amherst College, Colorado College, Cornell University, Oberlin College, Smithsonian Institution, University of California at Santa Cruz, and the University of Illinois at Champagne-Urbana.
