Description This image shows shrublands in Somalia from high above. Two images from 1952 (purple) and 2006 (green) are overlaid here for comparison. The colors highlight the large communities of shrubs and grasses which grow in bands along this sloping landscape. Over the fifty years shown here, all the vegetation has moved uphill the green bands of modern plant growth are further up the hillside than the purple bands from 1952. This is clear visual evidence that ecosystems like this change over time. Mathematician Karna Gowda measures and models these changes to understand how these dynamic ecosystems function and change.
These images stem from cutting-edge research on campus, winning our annual Scientific Images Contest which goes on display in galleries across Chicago.
Through partnerships with schools and community groups, we train Northwestern researchers to share their expertise and creativity in a community centered way. Sales from these images goes to support our education and outreach activities, connecting researchers to the wider community.
