Current Research
- Directing the USDA Caribbean Climate Hub.
- Arctic Observing Network (AON): Study of arctic ecosystem changes.
Past Research
- Furthering the science of remote sensing of biodiversity patterns.
- Documenting long–term response of arctic vegetation to recent climate change.
- Developing widely used landcover, biodiversity and conservation information for Puerto Rico and the US Virgin Islands.
- Developing the Forest Service Research Map Publication Series (RMAP).
Research Interest
My research involves integrating field and remote sensing data to analyze landscape patterns and processes in a wide range of ecosystems including tropical, temperate, boreal and arctic biomes. I am active in studies of conservation science, biodiversity, ecology, land cover mapping, modeling future scenarios for conservation planning, and field education and outreach.
Why This Research Is Important
There are a lot of uncertainties in how natural and social systems will respond to changes in climate and land use. My research helps better understand the current matrix of habitats, species distributions, and human use and infrastructure that make up the landscape - and how these might respond to things like sea level rise, increasing drought or storm frequency, urban growth, and other changes.

The Effects of Changing Land Cover on Streamflow Simulation in Puerto Rico
Year: 2015
Streamflow models were developed for Puerto Rico, Vieques, and Culebra simulating historic conditions from 1953 to 2012. When land cover was included in the model as changing with time, streams such as the Río Piedras with a high amount of human-ecosystem interaction were much better simulated. Thes...
The effects of changing land cover on stream flow simulation in Puerto Rico
Year: 2014
Rainfall, terrain, and use of the landscape affect stream flow and water resources availability.

New Fire Weather Zones and a Fire Danger Rating System Developed for Puerto Rico and the U.S. Virgin Islands.
Scientists Complete New Database for Modeling and Mapping Species Distributions
Year: 2013
Forest Service scientists completed two large project reports: The U.S. Virgin Islands Terrestrial Gap Analysis Project delivered to the USGS National Gap Program; and, Sportfish Gap: Conservation of Puerto Rico's Freshwater and Marine Recreational Fisheries Resources delivered to the Puerto Rico De...
Integrating Research, Education, and Traditional Knowledge in Ecology
Year: 2011
Integrating research and education is a fundamental goal of research institutions and agencies but specific approaches not widely published in environmental research journals. In this study, Forest Service scientists documented the costs and benefits to the public of engaging researchers, university...
Climate and vegetation change in Alaskan tundra.
Year: 2010
Studies of tundra vegetation changes in recent decades have predicted an increase in the relative abundance of shrubs in response to climate warming. In contrast, a detailed analysis of a 20-year record of tundra vegetation structure and composition from a set of permanent monitoring plots at Toolik...
Protected areas of Puerto Rico: Terrestrial and aquatic biodiversity protection.
Year: 2010
Forest Service scientists have mapped public and private lands designated for special protection in Puerto Rico. We identified 115 terrestrial and marine protected areas with 13 of them being exclusively marine.
Mapping snags and understory shrubs with LiDAR to assess wildlife habitat suitability.
Year: 2010
Forest Service scientists evaluated the use of LiDAR data for mapping the presence/absence of understory shrub species and different snag diameter classes in a mixed-conifer forest in Northern Idaho (USA).
