The Effects of Whole Genome Duplication on Functional Traits and Interactions With Arbuscular Mycorrhizal Fungi
… is one of the most pervasive forces driving plant evolution, yet modelling efforts on the establishment of polyploid plants have shown that early generation polyploids, or "neopolyploids", should experience high extinction rates due to a population demographic disadvantage. A major gap in …

Structure-function relationships in the water-use strategies and ecological diversity of the Bromeliaceae
… to emerge as a model system for the study of plant evolutionary ecology and physiology, and major advances have been made in understanding the factors involved in episodes of rapid diversification and adaptive radiation in specific bromeliad lineages. However, despite a long tradition of …

The Physiological Ecology of Fraser FIr in Southern Appalachian Cloud Forests
… projects. Finally, in the studies on the ecophysiology of regenerating size classes, no differences in gas exchange or water relations were found among the youngest age/size classes (germinant seedlings, seedlings, saplings). Furthermore, it was determined in greenhouse studies that gains …

Understanding the role of plant hydraulic traits in ecological processes
… respond to warmer and drier climatic conditions. Plant responses to drought occur at different biological and temporal scales, ranging from responses at the tissue level to responses that define species and populations. Plant hydraulic traits have proven to be key in the characterization of how …

Building A Mechanistic Understanding Of Biodiversity And Ecosystem Functioning In Forests
Biodiversity supports the productivity, resilience, and functioning of ecosystems over time. However, the underlying mechanisms of how biodiversity begets ecosystem function are still being uncovered. I sought to understand how tree diversity could influence local resource pools of light, water, …

Functional traits and resource-use strategies of native and invasive plants in Eastern North American forests
… non-native invaders seem to outperform native plants. Intuitively, it appears paradoxical that non-native species, with no opportunity for local adaptation, can exhibit greater fitness than native plants with this advantage. Here, I compared traits of native and invasive shrub and liana species …
