Yan Liu - PhD - genomics and evolution of UV reflectance in flowers

Research Summary: I am interested in the evolutionary forces that drive the diversity of angiosperm floral morphology. Previous research has focussed on the role of visible floral traits, and little work has focussed on traits that are harder to detect. With this knowledge gap in mind, I became curious what the role of UV reflectance is in the evolution of flora traits. I am using phylogenetic comparative methods to estimate correlations between UV parameters and other floral traits (e.g., tubuluar flowers, visible floral colour) across a range of angisoperm species using different models of trait evolution. I am also embarking on research on quantitative trait loci (QTL) of UV reflectance in the Mimulus model system (a genus that shows a high degree of variabilitiy in UV reflectance) to characterize the number and location of genes involved in the UV reflectance phenotype. Finally, I am interested in the genetic diversity of species that exhibit UV reflectance and am conducting a study that will reveal the demographic history and current population structure of Mimulus guttatus. Thus we can estimate the influence of past glacial periods placing geographical barriers that determine the current geographic distribution and potential for range expansion of this species. Implementing evolutionary principles of gene flow and genetic diversity with a fuller understanding of traits, both visible and invisible to the human eye, can provide a significant contribution to our understanding of how to conserve our natural resources.

Soraya Villalobos - PhD - specialization and ecosystem services in plant-pollinator interactions
Research Summary: My project aims to study the role of pollinator specialization in the reproductive ecology of plants. I integrate phylogenetic information with metrics of betadiversity for species and communities spatially segregated. Specifically, I am investigating large-scale patterns in phylogenetic turnover in plants and its pollinators comparing patterns in tropical vs different ecozones across Canada. My research emphasizes two key topics within the study of ecophylogenetic of plant-pollinator interaction: (1) geographical variation in pollinator specialisation and (2) the effect of pollinator specialisation on ecosystem services. I expect to gain a better understanding of ecological and evolutionary processes underlying community assembly and species turnover. Understanding these aspects are important to prioritise the management and conservation of local biodiversity.
