Species in ecological communities form tangled networks of ecological interactions. In these networks the nodes are all of different types as the species have different characteristics. Also the links can differ as we can include both negative - negative interactions (such as competition), negative - positive interactions (such as feeding) and positive - positive interactions (such as pollination).

We use mathematical and statistical models in order to analyse how these networks are structured and the factors that are driving the structural properties we see. As in all networks their structural composition is clearly coupled to their functioning and  understanding those relationship are also a backbone in our research.
