Could we reduce the functional diversity of plant communities to a few schemes?

The functional configuration of plant communities follows a limited number of dominant schemes, which are surprisingly similar to those found for individual plant species.

Too strong is the temptation to paraphrase the famous incipit of the novel ‘Anna Karenina’ by Leo Tolstoy:

Are plant communities all alike or is every plant community unique in its own way? “

The ‘Anna Karenina principle’ applied to plant communities is, in a nutshell, the core of the new paper we have just published in Nature Ecology and Evolution. The exuberance of the plant world when it comes to self-organizing into variously assorted communities puzzled ecologists for decades in their search for patterns and commonalities across regions. Thanks to the unprecedented collection of data made available by sPlot – The Global Vegetation-plot database, we found that the organization of plants into communities follows a limited number of dominant schemes, which are surprisingly similar to those existing at the level of individual plant species.

Are we asking too much of species data?

To conserve biodiversity, we need a clear picture of how it is distributed. Easier said than done! Biodiversity is a short word for a wide concept. Even just counting the number of species in a forest can be an overwhelming task if one considers all insects, spiders, birds, mites, (ticks!), lichens, fungi, isopoda and so on. Not only, some of these groups are very difficult to identify, so sampling them all would require hundreds of hours to a team of well-trained field biologists.

Can we rely on one or few groups of species to make inferences on all the other, then? Although the use of indicators is a well-established routing, how well these indicators work in Southern European beech forest is not clearly understood. One of the open questions is: How well do indicators work at different scales? In our new article Congruence across taxa and spatial scales: Are we asking too much of species data?”, just published in Global Ecology and Biogeography, we tried to find an answer.
