Biosis - H2 ZRCD (Page 11)

Provides (a) taxonomic hierarchy(ies) of the organism(s) discussed in the source docu-
ment. It allows you to locate information about an organism by using its scientific
name.

The broadest term listed is preceded by a single asterisk. The asterisks increase by one
for each lower taxonomic level. When more than one hierarchy has been assigned by
ZR editors over a period of time, the most recent is shown. All hierarchies assigned at
various times can be viewed in the thesaurus. Records from subfile 01, Comprehensive
Zoology, have no SY field.

All taxonomic and nomenclatural information (for example, SP-NOV) is linked to the
appropriate animal name in this field, and the author date for the animal name may be
included in these entries.

Search Example:

polioptila californica in sy
polioptilidae- in sy

Lists common names assigned to broad groups of organisms. To reduce the time spent
searching, use the ST field to search for groups of animals, such as

insects, instead of

listing all the groups separately, such as Hemiptera, Lepidoptera, etc. For the term
which best represents the category of organisms you want to search, browse the list of
"Super Taxa Terms" on page 37.

Search Examples:

Pseudo-field which combines the Descriptors (DE) and the Systematics (SY) fields. For
