Current Research

My current research projects address population ecology of the single mountain endemic platn species Packera franciscana and Erigeron mancus, and, on a retional scale, examine the climate change effects on timberline elevation and on over one hundred alpine plant species distribution.

Research Interests

My research studies are in plant biogeography and applied ecology, especially plant distribution along altitudinal and latitudinal gradients, alpine plant species distribution in the Southern Rocky Mountains, and ponderosa pine and Engelmann spruce tree spatial patterns.

Past Research

Past research has included studies on post-fire crown damage mortality thresholds in ponderosa pine, post-fire effects on ponderosa pine systems, exotic plant species in Northern Arizona ponderosa pine forests, vegetation ecology of Colorado Plateau hanging gardens, and fish ecology in Ozark freshwater streams.

Why This Research is Important

In the past, plant species have migrated in response to naturally changing conditions. Current global warming due to increased greenhouse gas emissions may also cause plant species to migrate or change population size as current local climatic conditions change. Land managers in the Forest Service need to know whether alpine treelines are moving upslope and which plant species may respond the most strongly to climate change. This research will provide species distribution and abundance data on which to base land management decisions.

    A recent collaboration has resulted in a definitive list of 609 vascular plant species and subspecies found in the alpine zone of the Southern Rocky Mountains. The Southern Rockies alpine plant species list shows the geographic distribution of each species and, in a major finding, documents 25 Southern Rockies alpine endemics--species that are found nowhere else in the world. 
    This research investigated plant density of a regionally rare threatened species, Packera franciscana, in order to detect current population size trends as well as establish a baseline to detect future climate change effects.
    This study measured the plant species composition changes within pika (Ochotona princeps) foraging zones compared to species composition 10+ meters outside of the zone.
