We study the dynamics and structure of terrestrial food webs.

Research

We focus on plant-herbivore interactions and how they are mediated by carnivores and soil-nutrient levels, both at the level of herbivore foraging ecology and plant-herbivore population dynamics.

We use a combination of empirical research and mathematical modeling to understand ecosystem structure and function. We deal with a variety of ecosystems and study species, ranging from seabirds on islands in New Zealand to insects and their spider predators in Connecticut old fields.

Current empirical research focuses on:

Functional Traits and Ecosystem Function

Ecosystem Resistance and Resilience

Global Change and Land-use

Evolutionary Ecology and Complex Adaptive Systems

Applied Research

Teaching

Os Schmitz teaches two primary courses:

  • Linkages of Sustainability
  • Biodiversity Conservation

 

Linkages of Sustainability: The Earth system is comprised of interdependent components—land, water, energy, biota, and non-renewable resources, all of which have physical limits. Societies transform these resources into useable goods, and production and consumption cycles connect people and places across space and time. This team-taught course provides an overview of these linkages and explores their implications for applying and measuring the concept of sustainability. It examines the constraints to sustainability imposed by those linkages (e.g., the energy required to supply water), opportunities for their transformation, and challenges of implementing sustainability across complex social and cultural systems. 

Biodiversity Conservation: This course introduces the student to concepts related to gathering and applying scientific information for problem solving in wildlife conservation. The course explores conceptually the kinds of ecological knowledge needed for wildlife conservation. Students also learn how to formalize that knowledge for effective decision-making. Relevance to real-world problem solving is the central focus of the course and students are exposed to numerous examples of applications throughout the term. Students also gain facility using the concepts and tools through written assignments and exams. The aim of the course is to provide students with a complement of concepts and tools that can be applied generally to environmental problem solving in wildlife conservation.
