Intraspecific trait variation and community assembly in old-field grasslands
<p>Trait-based approaches are increasingly used in plant community ecology, but previous research has largely ignored functional trait variation within species. Here I investigated the role of intraspecific trait variation in community assembly and responses to spatial and temporal environmental …

Population-Level Differences in Pinus monophylla Whole-Plant Seedling Strategies Under Varying Precipitation Pulses
… depends on the presence of functional traits that allow seedlings to survive selective pressures from altered climate regimes. Many widely-distributed plant species exhibit intraspecific trait variation reflecting adaptation to local environments. Populations may vary in traits that …

The response of grassland carbon cycling to drought events and changes in nutrient availability
… between functional groups, species and due to intraspecific trait variation. For soil microbial communities, the effect of drought on carbon use efficiency was modulated by short-term nutrient addition. Increased nutrient availability and drought therefore interact to determine how C is cycled …

Forests in a changing world: conifer leaf traits, community shifts, and climate change adaptation
… Pacific Northwest. In chapter 1, I examined the variation and covariation of leaf traits of conifer communities across a climatic gradient. I found that the contribution of species turnover to community-level trait values was tightly linked to climate while the contribution of intraspecific trait …

Effect of Population Sources and Species Pools on Community Phylogenetic and Functional Diversity During Restoration
… assembly can reveal new insights into how variation within dominant species interact with the local species pool to influence the structure of restored plant communities. Many studies have examined the effect of dominant species and species pools in structuring plant communities, but few …

The Role of Intraspecific Variation, Species Interactions, and Eco-evolutionary Feedbacks in Population Persistence
… Furthermore, recent studies have shown that intraspecific trait variation (ITV) in interacting species also influences population and species persistence. However, the effects of coevolution and incorporating ITV in two or more interacting species remain primarily speculative. This …
