King of the hill? How biotic interactions affect biogeographical pattern and species responses to climate change
As climate has warmed, many species have moved up mountains as physiological limits to their distributions have ameliorated. These distribution shifts are creating novel communities, begging the question: What happens to species at the tops of mountains as potential antagonists encroach upwards? The

Biotic and abiotic drivers of plant symbionts determine plant performance, the maintenance of diversity, and response to global change
Interactions among organisms regulate the structure and function of ecosystems and the response of ecosystems to global change. The outcome of species interactions is shaped by the partners involved in the interaction and the climate contexts of the systems in which they reside. Global change is alt
Global change implications of adaption to climatic variability
On the structure and significance of ecological niche breadth
The evolution of specialization in lycaenid butterfly-ant mutualisms
The effects of mine disturbance and contamination on pollination of subalpine wildflowers
Metals-rich soils can occur naturally or through human activity, such as mining. Plants growing in metal-rich soils often incorporate metals into their tissues; the concentration of these metals can vary among tissues within a plant, among plants of the same species, and among species. Accumulation
Beaver pond morphology as a tool for predicting changes downstream
As natural discontinuities of stream networks, beaver ponds have the potential to influence the structure and function of stream ecosystems. After declining during the extensive fur trade in North America, beaver populations have recently grown in some areas, especially montane regions. While previo
