query forms, accessible via the tabs labeled Genus, Species, and Publications, enable records to be retrieved from their corresponding data sources. Enter one or more search criteria using the
inputs described below, and press the "Search" button at the bottom
of the form. Records matching all search criteria will be retrieved.
Searches are not case sensitive.
Types On The Form
A simple text
box accepts a string of alpha-numeric characters and compares it against values
in the database. If the field in the database contains only numbers (e.g.,
"Publication Year" or "Accession Number"), only exact
matches will be retrieved -- wildcards and ranges cannot be used. If the field
is for text, a "sub-string search" will be performed. Searching
for "stella" in the species field would match "stella"
as well as "constellatus" and "castellatum", among others.
list box displays all the values that occur in the database, but allows only
one value to be used in a given query. The default value, [any]
causes the field to be ignored.
list box displays all the values that occur in the database and allows multiple
values to be used in a given query. Use Ctrl-Click to toggle individual selections
on and off; i.e., hold the Control key down (PC), or the Command key (Mac)
when you click on a value. Note, clicking a value without holding down
the control key (i.e., a simple click) clears all other selections in the
list box and leaves the most recently clicked value as the only selection.
Note also that some browsers "remember" selected values between
queries even though the selected values are not visible (i.e., have scrolled
off) the list box. Press the Clear button to clear the form.
- Radio Button
A radio button must have one and only one selection chosen out of two or more choices.
- Name of genus. Exact match, or use wild card (%) e.g. "Azpeit%" will retrieve "Azpeitia" and "Azpeitiopsis".
- Species epithet. Exact match or use wild card (%). Because of the variability in epithet endings, we recommend the use of the wild card, e.g. "hustedti%" will retrieve "hustedti" and "hustedtii", "marginat%" will retrieve "marginatus", "marginata", "marginatum".
- Infraspecific epithet:
- Third element of a trinomial. Taxa below the rank of species are treated as trinomial in accordance to Art. 24.1 of the ICBN, which states “The name of an infraspecific taxon is a combination of the name of a species and an infraspecific epithet. A connecting term is used to denote the rank”. Exact match or use wild card (%). Because of the variability in epithet endings, we recommend the use of the wild card.
- Author of basionym
Searching for “Mann” will retrieve “Mann”, “A. Mann”, “D.G. Mann”, and “Janisch ex Mann” but not “Honigmann”. Wild card not available.
- Author of combination
- This field contains data only for new combinations (name of the combination author) e.g. “Mann” will retrieve “Mann”, “A. Mann”, “D.G. Mann”, and “Janisch ex Mann” but not “Honigmann”. Wild card not available.
- Publication year
Exact match or use wild card (%), e.g. “191%” will retrieve names published between 1910 and 1919.
- Publication number
A unique number assigned to a record in the publication table. This is the number of the publication where a given name was published. Exact match.
- Display options
- Page Style - Multiple Pages/Single Page
- Choose Multiple Pages if you would like the results displayed 20 per page, one page at a time. If you would like all the results displayed on one page, choose Single Page.
- Record Style - Brief Records/Full Records
- Brief Records will display only a few fields of data for each record. Full Records will display all of the data for each record. Be warned that choosing Single Page and Full Records can take a long time to download if there are a large number of records.
- Query feedback
- The query parameters entered on the form are summarized in query language at
the top of every result page. Read the query statement to be sure that the query
being processed is what you intended. Some browsers have a tendency to "remember"
parameters from previous queries. Press the Clear button between queries
to clear previously used parameters.
- Number of records
- The number of records retrieved by every query is reported immediately after
the query feedback (near the top of the page) as the results are being formatted.
If the number returned is much larger than you expected or want to wait for,
press the "STOP" button on your browser to cancel the query. You can
create a more restrictive query by entering additional search criteria on the
- Retrieval limit
- The number of records retrieved is limited to 500 to prevent "excessive
resource consumption" by a single user and to prevent browser crashes;
large result sets can cause some computers to lock up. Note that 500 taxonomic
records amounts to more than a megabyte of data. If you need a result set larger
than 500 records please contact Sarah Spaulding or Jean DeMouthe.
- Output format
- We hope
the content and structure of retrieved records will be self explanatory, but
some of the field definitions below may provide additional insight. At present
the only type of output is HTML. We hope to provide structured text and XML
in the future. Depending if choosing “Full Record” or “Brief Record”, each entry includes the following information:
- Brief Record:
- Scientific name (binomial or trinomial) with its author and date of publication.
- Full Record:
- Certain fields, if blank, are not displayed in the results. Therefore, some of the fields listed below may not appear in your search results.
- Scientific name (binomial or trinomial)
- Taxa below the rank of species are treated as trinomial in accordance to Art. 24.1 of the ICBN, which states “The name of an infraspecific taxon is a combination of the name of a species and an infraspecific epithet. A connecting term is used to denote the rank”.
- The authorship is cited in accordance with ICBN Art. 46-50. When authorship of a name differs from authorship of the publication in which it was published, both are cited, connected by “in”. “Ex”, inserted between author A and author B indicates that the name only is attributed to author A, and the validating description is attributed to author B.
- For names of taxa assigned to a different genus than the genus in which it was originally described (new combinations), the authorship consists of the author of the original name (basionym) enclosed in parentheses before the author of the new combination. In "(Ehrenberg) Cleve", for example, Ehrenberg is the basionym author, Cleve is the combination author.
- Date of publication
- The date on which the publication became available (see ICBN Art. 29-31). We provide only the year of publication (to the best of our knowledge).
- Page and plates number(s)
- For names of new taxa, the page cited corresponds usually to the page where the validating description begins, and all the figures where the new taxon is illustrated. For some records, the pages given are that of the extent of the protologue, or of the extent of the description.
- For new combinations, and replaced names (nomina nova) citation of just the page(s) where the name is published would suffice, however, for most of the entries originally contributed by VLC (VanLandingham’s Catalogue) and ANSP (Academy of Natural Sciences Philadelphia, New species File), the pages given correspond to the citation of the taxon concerned, and include also references to illustrations. For those we did not change the format of the page citation and also included citation of the illustrations. Entries contributed by INA (Index Nominum Algarum) and CAS (California Academy of Sciences) only cite the page(s) where the conditions for valid publication are fulfilled.
- Name as originally published
- Name as originally published appears below the scientific name when it differs significantly from the scientific name.
- Publication number
- A unique number attached to each reference at the database at CAS.
- Published in
- Full citation of reference where the name was published.
- Basionym and replaced synonym
- In the case of a new combination, the basionym is the oldest name with the same epithet that applies to the same type. It is usually the oldest nomenclatural synonym, but not always. The basionym is cited with its author(s) and date of publication.
- Example: Amphora ovalis (Kützing) Kützing 1844 has for its basionym Frustulia ovalis Kützing 1833, which is a new name for Navicula amphora Ehrenberg 1832.
- In the case of a nomen novum (new name), the replaced synonym is cited as part of the comments.
- Unless the basionym or replaced synonym is also in the Abas-Bruniopsis section, its complete entry is not to be found in this volume.
- We indicate for the record we have assessed, the nomenclatural status of the name (Valid/Invalid). Illegitimate names (e.g. late homonyms, superfluous names) are also indicated as such.
- Remarks on the nomenclatural status of the name such as invalidity, and notes on illegitimate names are included.
- Our assessment may change as rules governing the status of names are subject to change. The rules applied here are those of the Saint-Louis Code (Greuter et al. 2000). The Vienna Code (McNeill et al., 2006) will be taken into consideration for any further work in this database.
- Links to the INA database
- Whenever possible we provide a link to the Index Nominum Algarum (INA) (see http://ucjeps.berkeley.edu/INA.html), a database of algae names (including at leat 40,000 diatom names) compiled by Paul Silva and maintained at the Herbarium of the University of California, Berkeley. The INA consist of a combination of cards (image cards) that can be viewed, when available by clicking “view INA card”, and keyboarded entries that can also be accessed by clicking at the designated place.
- Type information
- Information on type specimens, type locality, collector, etc.. is included for a limited number of record.
- This information, however, has been routinely included by Paul Silva in the INA. If a corresponding record exists in the INA, links to the INA database will show this information.
- Assessment of record accuracy
- We have personally verified 50% of the records. In addition, many records that we did not verify show no discrepancies between data sets (e.g. INA or ANSP). We are therefore confident that 70% of the records are accurate and we indicate those as “likely accurate”. We are actively working on verifying those 30% records labeled “uncertain/not verified”.
- List of nomenclatural synonyms
- All nomenclatural synonyms (=homotypic) for a given name should be listed. We are still improving the links between all nomenclatural synonyms of a given name, and some synonyms may be missing.
