BacSim: Individual-based model of microorganisms
- BacSim is an Individual-based Model (IbM) of bacterial populations, such as colonies and biofilms. Online computer simulations give a feel for what the program does. Source code and animations are also available.

Astrobiology Web
- Microbes and other life forms in extreme environments. (Although the title of this site implies that it is about space, this is an excellent resource about microbial ecology in unusual environmental conditions here on Earth.)

The Center for Microbial Ecology (CME)
- The intellectual focus of the Center for Microbial Ecology is to understand factors that influence the competitiveness, diversity and function of microorganisms in their natural and managed habitats.

Digital Learning Center for Microbial Ecology
- Michigan State University website with extensive resources on microbes and the environments they live in, as well as links to other microbial ecology resources on the web. Includes the Microbe Zoo.
