1. interactions with other organisms Amelia Ireland and Jane Lomax

2. The Ontology

3. Lack of Counterpart Terms

4. The Non-host Problem

5. The Non-host Problem II

6. Solutions Remove non-host designation Add generic processes with the wording other organism Add existing host and new symbiont terms as children Append terms with during symbiotic interaction to clarify

7. Solutions E.g. acquisition of nutrients from host acquisition of nutrients from other organism during symbiotic interaction acquisition of nutrients from host acquisition of nutrients from symbiont

8. Solutions: before

9. Problems with Viruses

10. Solutions: viruses Generalize virus terms to apply to any organism Processes with specific viral variants can be renamed Reassess terms and annotations to see if they refer to host or virus processes; add new terms as required Rehome terms under interaction with other organisms

11. Solutions cell communication / signalling cell adhesion / fusion (e.g. membrane fusion) cell death response to biotic stimuli from other organisms behaviours involving other organisms, e.g. mating entry into / engulfing / incorporating another organism movement within another organism exit from another organism phagocytosis nodulation pollination

12. Questions Is response to other organism equivalent to interaction with other organism? Is multi-organism biological process equivalent to interaction with other organism?
