How plant communities change when conquering uninhabited ground
Press Release of 17.09.2024
Some plants are able to take over uninhabited spaces like sand dunes, volcanic substrates and rockfall areas. The first colonizers have specific traits that allow them to grow in such hostile environments. Other plants lack such traits but will soon follow these pioneers. Ricardo Martínez-García from the Center of Advanced Systems Understanding (CASUS), an institute of the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and collaborators from Spain and Brazil investigated the type of interaction between different species on these newly conquered grounds with the help of a mathematical model based on existing root physiology knowledge. Their new model connects the type of species interaction with the general availability of a scarce soil resource. It also reveals the best strategy for the pioneer who can harness a resource that is not freely available.
