Research Overview

The overarching goal of our research is to understand the interactions among people, land, and biodiversity. Research projects focus on housing growth and its ecological effects, land cover and land use change analysis, and the assessment of wildlife habitat and biodiversity patterns. We conduct our research at broad spatial scales. Remote sensing, GIS, and statistical modeling are our most commonly used research tools.

All projects are conducted in close collaboration with land managers and scientists in organizations such as the U.S. Forest Service, the Nature Conservancy, both the Polish and the Russian Academy of Science, and the WWF. Via these collaborations, we hope to contribute towards the goal of a sustainable future.

Using Land Use Change Projections to Estimate Threats to Freshwater Ecoystems


Freshwater ecosystems are essential for humans and biodiversity, yet they threatened by human activities. Sebastian Martinuzzi's study assessed the consequences of future land use change on freshwater ecosystems in the US.

Sacred Forests in northwest Yunnan, China: a conservation priority?


Tibetans in Yunnan, China, protect small forest areas near to their villages. While these areas may contribute to biodiversity conservation across the landscape, should they be incorporated into conservation planning?

Forest degradation in Mexico and spectral mixture analysis


Forests of Mexico are under threat due to development, both for urban and agricultural purposes. However, it is not clear the spatial and temporal extent to which this is happening. SILVIS PhD candidate, Carlos Ramirez Reyes is exploring this using remote sensing data, and a novel method, spectral mixture analysis.

People's attitudes toward protected areas matter - but at what scale?


Attitudes of people living in close proximity to protected areas can reflect on the effectiveness of management strategies within their borders, and understanding the spatial scale at which these perceptions occur may help to focus conservation efforts.

Birds that Love Insects that Love Lakes: How Insect Populations and Lake Characteristics Impact Avian Aerial Insectivores in Northern Wisconsin


Paul Schilke, MS candidate in the SILVIS Lab, is conducting research in northern Wisconsin to investigate how insects that live around lakes affect the birds that feed on those insects.

The potential effects of extreme weather events on bird reproductive output


Extreme weather events are expected to increase in the future. Extreme weather could result in population declines if these strike during the breeding season for North American passerines.

The power of maps and the beauty of old ones


Historical maps are pretty AND useful. Catalina is using them to determine the effects of past land use on subsequent land cover change in the Carpathian Region of Europe.
