Shallow-water bryozoans from the Azores (central North Atlantic): native vs. non-indigenous species, and a method to evaluate taxonomic uncertainty
Bryozoan records from the shores and upper shelf (≤50 m depth) of the remote Azores Archipelago (central North Atlantic) have been analyzed, along with unpublished data and data from recent surveys. A checklist of 67 shallow-water species is hereby compiled for the region, of which more than one thi...
