Polytraits: A database on biological traits of marine polychaetes

  1. 1. A database on biological traits of polychaetes http://polytraits.lifewatchgreece.eu Sarah Faulwetter Hellenic Centre for Marine Research
  2. 2. http://polytraits.lifewatchgreece.eu background ● first started in-house in 2006 ● aim: collecting traits to perform BTA ● initially: dataset with 102 polychaete species from Mediterranean lagoons ● manual text mining ● link to citation, original text snippet recorded ● data collection: purpose-driven, not systematic
  3. 3. background ~ 1000 species-level taxa 950 literature sources ~ 20,000 records semantically described terms current aim: data mobilisation
  4. 4. background
  5. 5. background ~ 1000 species-level taxa 950 literature sources ~ 20,000 records semantically described terms current aim: data mobilisation
  6. 6. background ~ 1000 species-level taxa 950 literature sources ~ 20,000 records semantically described terms current aim: data mobilisation
  7. 7. trait selection
  8. 8. trait selection Consultation of existing literature & databases Creation of list of traits & modalities Adaptation for polychaetes Definitions & ontology mapping mainly: BIOTIC, papers by Bremner et al., Annelid reproduction (Rouse & Pleijel) All traits are categorical Each trait has several modalities Each modality can be present or/and absent Polychaete-specific traits, e.g. pharynx structure, epitoky, range of body sizes... Clear definition of traits, mapped to existing ontology concepts where possible
  9. 9. trait selection
  10. 10. trait selection 21 17 9 adult traits reproductive traits larval traits 47 traits, 252 modalities ca. 5 traits “unsuitable”
  11. 11. problems encountered “Unsuitable” traits ● Trait not applicable for polychaetes: “migration” → there is no significant migration in polychaetes
  12. 12. problems encountered “Unsuitable” traits ● Trait not applicable for polychaetes: “migration” → there is no significant migration in polychaetes ● Trait “wrongly” defined e.g. “Sociability” should be either “solitary, gregarious...” or “commensal of ..., parasite of..., ….”

  14. 14. problems encountered Modalities too specialised
  15. 15. problems encountered Modalities too specialised

  17. 17. problems encountered Traits with “endless” modalities

  20. 20. problems encountered Overlap / Correlation of traits & modalities
  21. 21. problems encountered Missing traits ( & modalities) ● Larval & adult dispersal potential ● Additional morphology traits, e.g. sensory organs ● Resistance to physical disturbance ● Environmental position (infauna, epifauna,...) ● Socio-economic traits
  22. 22. If I could do it again...
  23. 23. Wishlist ● Clearly define each trait and modality from the beginning, incl. examples ● Introduce hierarchy of traits ● Avoid conversion of numerical values into categories ● ● ● ● Weighting mechanism (e.g. “usually found on sand, rarely on mud”) Add flags for uncertainty Add geo-coding of origin of information (same species does different things in different areas) Introduce species interactions
