Our current work revolves around population dynamics in space and time, climate change, resilience, and autonomous sensing technologies.

Some highlights of my past work (summarized in 2024):

  1. Species' Borders: In his work with RD Holt, Keitt explores the ecological and evolutionary dynamics of species' borders, emphasizing their importance in understanding biodiversity and species distribution (Oikos, 2005).

  2. Wavelets in Ecology: Keitt, along with DL Urban, developed scale-specific inference tools using wavelets to understand spatial patterns in ecology, addressing the challenge of inferring relationships across different scales (Ecology, 2005).

  3. Ecosystem Services and Land-Use Change: Collaborating with several authors, Keitt created a conceptual framework to understand how land-use changes impact ecosystem services provided by mobile organisms such as pollinators (Ecology Letters, 2007).

  4. Network Approach to Species Diversity: Keitt and EP Economo applied network theory to neutral metacommunities to understand spatial biodiversity patterns, linking these patterns to dispersal and community dynamics (Ecology Letters, 2008).

  5. Circuit Theory in Ecology: Keitt used circuit theory to model ecological connectivity, providing insights into preserving and restoring connectivity in complex landscapes (Ecology, 2008).

  6. Spatial Synchrony in Population Dynamics: With ON Bjørnstad and others, Keitt examined how dispersal and environmental correlation contribute to spatial synchrony in population dynamics, an important aspect of ecological stability (The American Naturalist, 2000).

  7. Graph-Theoretic Approach to Landscape Connectivity: Keitt explored the use of graph theory to evaluate landscape connectivity, highlighting its application in conservation biology (Landscape Ecology, 2009).

  8. Microbial Responses to Environmental Change: Collaborating with CV Hawkes, Keitt studied microbial community responses to environmental changes, emphasizing resilience and historical contingency in ecosystem processes (Ecology Letters, 2015).

  9. Historical Contingency and Species' Borders: Keitt's work on species' borders also includes investigating the impact of historical events and local interactions on species distribution limits (The American Naturalist, 2001).
