Yvonne Baskin is a skilled science writer who only seems to write about things I find really fascinating. There's a strangely institutional flavor to her works, since they're very explicitly hired out projects of SCOPE. It almost seems like this explicitly educational purpose has kept her from widely popularity, but maybe that's just because I imagine everyone would want to read about this stuff if they knew these books were around, and maybe that's not true.
In this work, Baskin sets out to present the then-new and burgeoning research on ecosystem services, the ways they are being assaulted and diminished, and the connection to biodiversity. I picked it up to review the breadth of ecosystem services in general, but more specifically because I had a few questions about conservation biology and restoration ecology and I knew this would be a good entry point.
My specific question stemmed from the recent trend in conservation towards "biodiversity," premised on the idea that species are valuable treasures and have a moral status that warrants against their blithe destruction, but more interestingly on the idea that there are serious consequences to losing too many species. That is the collapse concept: ecological degradation will trigger a rather sudden shift of state to a global situation that no longer supports industrial civilization. I wondered how well understood the connection between biodiversity (essentially, how many species are still around) and ecosystem services.
The Work of Nature undertakes to address that question. The answer, incidentally, is that diversity is correlated with stability and resilience. Communities with low diversity are more or less maximized for whatever set of conditions presently obtains. In high diversity communities, when conditions change, species groups better adapted to those conditions gain competitive advantage and take over the main work of the ecosystem; in low diversity communities, conditions adverse to whatever happens to be around directly impair functionality.
Beyond answering her basic question, however, Baskin surveys a vast array of interesting ecological research and paints a fairly thorough picture of the complex relationships involved. She chooses not to distract from her narrative by personifying the scientists at all, but she still always names them and places their research in the context of its region and biome. This brings home the fact that the research is extremely limited so far, and its conclusions generalize poorly: there are many relationships she describes that obtain in one place but not one I'd expect to behave similarly.
The overall impression is that this kind of research is fantastically productive and interesting, and infinitely necessary, though frustrating in its infinite complexity. It reassures me that agroecology is both a fertile and valuable field to enter!
