Spent some time applying the inclusions and exclusions in the Wiki above to a RG collection project. Worldwide Marine Life. Duplicated the rules but as a RG and Needs ID project for a local place Salish Sea Marine Life.
The significance of limiting the worldwide project to RG is so that land based crabs, gastropods etc don’t show up because they have only been identified to family etc. A
¬_in_project=worldwide-marine-life
could be used to specifically look for land based organisms of interest.
Also for this project, worked on Ray-finned Fish exclusion heavily supplemented by rules from other marine fish projects, and heavy handed cherry picking from the resulting map to exclude species, genus, and or families etc of fish - one thing with fish is that in some cases a single species, or so it appeared, within a large genus had evolved to live solely in freshwater.
Also cherry picked species, genus, and or families of organisms such as crabs, flatworms, Chromista (maybe too much), and etc.
This still needs some auditing and editing. Need to audit @w_martin exclusions and inclusions to see if these are all used - working on that currently. Some birds such as loons, ducks and etc have not been included because I am unsure as to how much of their life cycle/time is spent in a marine environment. Fish could be further checked by someone who is very much into ichthyology.
As mentioned in the project About - diadromous fish ((fish that migrate between fresh and salt water) and migrating (or way off course) birds blur the inland boundaries - there are more of these bird observations in the western northern hemisphere from what I call the ebird vagrant effect (EVE) - multiple people documenting posted vagrants.
