Ecological interactions are the wireframe of biodiversity. No single species on Earth lives without interacting with other species. Thus, biodiversity is more than just species: interactions among them are the architecture that supports ecosystems. It’s the Web of Life.
Just in the same way we sample individuals of free living species to estimate the diversity of a particular area or ecosystem, we can sample interactions. In this way we can assess the full complexity of ecosystem structure.
