There is a good chance that Issues about biodiversity at the macro scales transfers, at least partially to what happens at the microscales. The problem is that at the micro scale, in large scale ecosystems there are not good sampling techniques to make comparisons. Metagenomics is currently the only way, and energetics is hard to gauge through these techniques, except indirectly (populations studies at the micro-scale are hard to generalize) and then there's the problem of lateral gene transfer, and implications for evolution in these environments, But this is an issue in the gut as well.

> Jennie, thanks for pointing this out. The project I'm working on is actually looking at bacterial populations inside the ecosystems of the human body; the specific message we are looking to share is the fact that lower diversity of microbes in the human microbiome is correlated with disease states in the human body, and higher diversity of microbe populations is correlated with healthier human systems. So the analogy of ecosystems on a macro-scale (forests, grasslands) is certainly a stretch--but as we brainstorm ideas, it seemed worth asking if folks knew of activities that might be adaptable to the topic of microbes. ::grin::

The concept has experienced massive changes in popularity since the early 50s, but even with more precise definitions of diversity and community resilience and some better data (e.g. Tilman 2006/grasslands), I'm not seeing a consensus for the idea as applied to all kinds of communities. But maybe I'm behind the times?

Is anyone in the informal education world using games to talk about the importance of species diversity of ecosystems? (It seems like something that would be a great subject for playful interaction, but I can't think of any actual games I've come across that address this topic specifically.)
