Functional traits and resource-use strategies of native and invasive plants in Eastern North American forests
… species invasive to this region have superior resource-use strategies, or alternatively, they share the same metabolic tradeoffs as the native flora. First, at a global scale, I addressed the largely untested hypothesis that biogeography places significant constraints on trait evolution. …

Effects of plant invasions on ecosystem processes: Linking above- and below-ground resource-use strategies of native and invasive species in Eastern U.S. forests
… may have different above- and below-ground resource-use strategies that can profoundly alter ecosystem processes. Here I investigated above- and below-ground plant traits and soil properties associated with resource-use strategies and soil nitrogen (N) dynamics for multiple native and …

The nitrogen cycle and ecohydrology of seasonally dry grasslands
… and leaf conductance that maximizes efficient use of available water. That is, fertilization-induced increases in leaf area index are offset by reduced leaf area-based stomatal conductance. When primary productivity is assumed to be co-limited by water and nitrogen availability, total surface …

Population-Level Differences in Pinus monophylla Whole-Plant Seedling Strategies Under Varying Precipitation Pulses
… vary in traits that regulate seedling growth and resource acquisition in response to resource pulse regimes, and some adaptations to historic conditions may become maladaptive under projected climate scenarios. Singleleaf pinyon pine (Pinus monophylla) is a dominant tree species in the …

Rooting for the Home Team: Arbuscular Mycorrhizas and Root Traits in Native and Invasive Woody Shrubs
… future invasions. This dissertation focuses on belowground aspects of these invasive species, including linking arbuscular mycorrhizal fungi (AMF) to invader growth responses, investigating the relationships between AMF community composition and their plant hosts, and understanding the …

Society and nature in the Lower River Nyando Basin, Kenya
… at terminology and suggesting a more conscious use of vocabulary in order to improve the way we reason about society-nature relations. The terms risk, vulnerability and resilience are used as examples, as they are prevalent in natural and social science. Concerning (a) it is concluded that we …
