but occurrence records are sparse typical of
marine organisms of little or no commercial value
8
Macrodactyla doreensis sparse distributional
data
Point occurrences and generalized range maps data
convey very different impressions and types of
information. How should the range polygon be
drawn?
9
Occurrence records use symbols of a different
color for each synonymous name -- can be used for
investigating whether a synonymy is justified.
MAPPING SPECIES OCCURRENCES
SUMMARIZES KNOWN RANGE OF SPECIES

Is there are any way of assessing such

biotic attributes that control occurrence
