Local communities and regional biotas are built of hundreds, if not thousands, of species. Most of these species are small-bodied and discreet lifeforms. So it’s no wonder that naturalists have almost always focused their attention on conspicuous species of their particular liking. Why plants then? Well, plants are practical and efficient. They “stand still and wait to be counted”, as the eminent population biologist John Harper put it. No matter the weather, from spring to autumn. There are enough plant species to show contrasts between sites, and yet they can usually be identified to species level in the field.
You Can’t Predict the Diversity of Beetles from Lichens… Can You?
Unfortunately, the overwhelming scientific consensus seems to be that any particular taxonomic group won’t adequately represent the biodiversity of other taxonomic groups. The idea of surrogacy seems to hit the same hard wall as most attempts to provide generally working models for variation in biodiversity at local and regional scales. Biodiversity remains one of the largest scientific research questions without good general answers. Continue reading
