Which plant species grow where, alongside which others - and why? In a new study, an international research team presents the world's first global vegetation database which contains over 1.1 million complete lists of plant species for all terrestrial ecosystems.
Nature establishes relationships between species and organisms, forming a very complex network where often great-interconnected nodes appear. They are called 'hubs'. But humans also create this kind of networks, such as airports as nodes and flights as connections.
An extensive review of studies and databases reveals that drought and an increase in temperature are already causing species substitutions, greater aridity, higher forest fire risk, lower soil fertility, and lower water availability, among other negative impacts.
