About

This Wikibase instance assists in data modeling related to ecology, with an initial focus on invasion biology and adjacent fields like freshwater ecology, restoration ecology and urban ecology.

good starting points here are

• the entry for the enemy release hypothesis in general (Q2).
• the entry for the performance sub-hypothesis of the enemy release hypothesis (Q19).

General comments

• I like the option to have several hypotheses types and thus several formalizations as triples, this nicely represents the ambiguity in the existing definitions
• So now, we give the formal structure as part of each definition item. If the definition does not allow a formalization since it is too complex or vague, there is no 'hypothesis type' statement in the definition item and no 'structure of the hypothesis' is given
• Every way to formalize that I found meaningful is now added with a separate definition; in many cases these will need nanopublications to make them citable
• check out Q87 as an example: The different versions are modeled now with separate definitions (that demand for respective nanopublications)
• for the relationships, I now used the more general versions from our relationship list (i.e. level 1, 2 or 3, not 4, e.g. 'positively affects' instead of 'contributes to', 'facilitates' or else), see https://nimbus.igb-berlin.de/index.php/s/WkMGdEM5AL9WmFy

• The latest versions of the hypotheses are marked as 'status of the property': 'Ready for group review' (P36, Q145) and can be identified with the query below

• I modeled sub-hypotheses only for the ERH for now; also, only for ERH, BR and PH references to the original papers and definitions are included
  • maybe the missing sub-hypotheses and key references can be added in wikidata directly, once we started transferring everything there
  • but we need to decide (a) how to model the key references (see below) and (b) which sub-hypotheses to include (see here: https://nimbus.igb-berlin.de/index.php/s/fMorDtDixbC3z7H)

To be decided

• How to include the original references for a hypothesis
  • in Q110 and Q51 we modeled it by using 'described by source' - might be the best solution?
  • See e.g. the biotic resistance hypothesis version 2 (Q102) - we would need to cite the original paper here
    • Ideally, we would look up the exact quote and give the two earliest references cited in Jeschke et al and Daly et al, i.e Elton (1958) and Levine and D'Antonio (1999)
    • to spare some work, we could also model these as part of the respective definitions, e.g. add in Q105 a statement 'based on' and then give these two papers?
  • see comments added to Q39: Based on or described by? Add a new property 'formalized by'?
  • Q9: here we used 'cites', and gave the information on the key reference in the item for the respective definition paper
  • "stated in" P31 would be yet another way to express that
• Question specific for the enemy release hypothesis version 2 entry (Q76): How many definitions do we want to include? All those listed in table 1 here (https://docs.google.com/document/d/1phJRNswtowlthVUw5UfvqhOJTssi5I74/edit#)?
• which terms to use: exotic / alien / non-native (for species and range)?
  • decision was to go for non-native everywhere
  • todo: update everything accordingly
