Taxonomy
There are 11 species of Portuguese oak trees, a new list states
For several decades it said that there are eight native Quercus in the Portuguese flora, but a new botanical list raises the number of these species of Portuguese oak trees to 11, the result of a long and complex research work led by Carlos Vila-Viçosa.
Taxonomy: the way science organises biodiversity
With an estimated 8.7 million species on the planet, a robust system is needed to name, describe and organise so many life forms. For this task, biodiversity relies on taxonomy, a system that helps to identify and study species so that we can recognise and conserve them.
