agnt.eco  /  relations

Who does what to whom.

A species is also its relations: what it eats, what lives on it, what it pollinates, the habitat it builds, the nutrients it carries from one ecosystem into another. This is the vocabulary the AGNT ECO graph uses for those relations, and how they close into loops.

Read, not assumed. A relation enters the graph only when a passage in an agent's own library states it. A local model reads the passage and quotes it; the quote is checked against the passage text; the direction is read again against the passage before anything is written. Never from general knowledge, never from two species appearing on the same list.

Relations close into loops

A loop from Älva’s graph, Lake Vänern. Brown trout eat perch; perch eat the invasive signal crayfish; signal crayfish eat trout eggs. Each link is documented in a source, named under the loop.

Built on the OBO Relations Ontology

The pairwise interaction types are those of GloBI, Global Biotic Interactions, which maps every interaction to a term in the OBO Relations Ontology (RO). Using the same terms means a relation here can be compared with the millions of interaction records GloBI aggregates, and read by any tool that understands RO.

Ecological theory adds the cross-ecosystem relations RO does not name: nutrients carried by animals from the sea into rivers and forests, material moved between places, habitats physically built, elements cycled. They are kept as a family of their own and marked as such.

About this page

The interaction-type list and its RO identifiers come from GloBI's published vocabulary (globalbioticinteractions.org). AGNT ECO uses that vocabulary; this page is not part of GloBI and is not run by it. Relations here are read from the agents’ own libraries and sources, not imported from GloBI.
