2. Check if plotted distribution agrees with reported distribution in the database.

3. Edit mapping parameters
Case 1:
Plot not generated for an area(s) in the map where species is described or known to occur
Case 2:
Plot generated for an area(s) in the map where species is not described or known to occur

4. Possible Actions/Solutions
Checking FAO Area data/bounding box extents (sample)
Adjust environmental envelope
- check species summary for additional info
- sample available point data
- characteristic parameters of key areas (sample)
Adding “good cells”
- geographic coordinates from literature, other species databases, gazetteer
- expert input
- direct entry of coordinates or select from map
Deselecting point data

7. Examples Key Areas
Arafura – very shallow depth (~50m)
Red Sea, Mediterranean Sea, Persian Gulf – high salinity
Yellow Sea, Black Sea, Sea of Okhotsk – low salinity

9. Getting Expert Input
vague distribution (ex. point data for circumglobal species)
finding “good cells” (ex. 10 gc requirement; area of known occurrence but w/o occurrence data)
outliers from a reliable source
bimodality in environmental parameter distribution
species with unknown or under-investigated taxonomic status
difficulty fitting distribution after changing more than 2 environmental parameters

12. Document changes with screen capture of initial and edited versions of species distribution map.
Ex. Abudefduf saxatilis – strictly Atlantic species; removed FAO Areas 51, 57 and 71 from FAO areas record
