The query form enables you to retrieve specimen
records by virtually any combination of fields present in the database.
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 the query is reported
immediately after the query feedback (near the top of the page) while the results
are 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 adding additional criteria
to the form.
Retrieval Limit. The number of records retrieved is limited to 1,000
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 1,000 records can amount to more than 1.5 MBs of data. If you
need a result set larger than 1,000 records we will be happy to prepare a file
for you and make it available via FTP. Please contact Jens
Vindum or Stan Blum for assistance.
Input Types On The Form
- Text Box
A simple text box accepts a string of alpha-numeric characters and compares
it against values in the database. The input string must match the entire
value, unless wildcard characters are used. Wildcard characters are the percent sign
(%) and the question mark (?). The percent sign matches zero to many characters,
whereas the question mark matches one and only one character. For example,
searching the species field with "rhino%" will match "rhinoceratus"
- Single-Select List Box
A single-select 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.
- Multi-Select List Box
A multi-select 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 (Windows),
or the Command key (Macintosh) 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
in (i.e., have scrolled off) the list box. Press the Clear button to
clear the form.
- Check Box
A check box allows a particular criterion to be turned on or off (ignored).
- Radio Button
A radio button must have one and only one selection chosen out of two or more choices.
- A single-select list box. The two values, Amphibia and
Reptilia, are self-explanatory. This field may be most useful to researchers
doing faunal studies within particular geographic region.
- Order / Suborder
- A single-select list box. The nine values used in the
catalog are listed in the table below, as are the corresponding numbers of
lower taxa and specimens.
||Scientific Name of
Order / Suborder
||Frogs and Toads
||Salamanders and Newts
- A text box. The scientific name of the family in which
a specimen is classified.
- A text box. The genus name applied to a specimen.
- A text box. The specific epithet of the scientific
name currently applied to the specimen. Wild cards are allowed. The taxonomy
used in the database may be slightly different from usage elsewhere. For example,
species named after a person may end in "i" or "ii" and
are commonly inconsistent across collections. If part of the taxon name is
in question, use an percent sign (%) as a wildcard, e.g. "boyl%" instead
of "boylii". Note that type specimens are identified according to
current classification rather than the name for which they are the type. Names
fixed by the type are listed in the Remarks field.
- A text box. The subspecific epithet of the scientific name currently applied to the specimen. Wild cards are allowed.
- Type Status
- A single-select list box. The values used in the catalog
and the corresponding number of specimens are listed in the table below.
Because the values in several geographic fields contain a suffix (e.g., "Co.",
"Ids.", "Id.", "Div.", "Prov.", "Region",
etc.) using just the place name as an exact match criterion will find no matching
records. These fields are therefore configured to append a wildcard (%) automatically
to the any value entered in the State, County, Island Group and Island fields.
- Continent / Ocean
- A multi-select listbox. Indicates the largest natural
geographic where the specimen was collected.
- A multi-select listbox. The primary political unit where
the specimen was collected.
- State / Province
- A simple text box. The name of a secondary geo-political
unit, typically a state or province, where the specimen was collected. If
the unit-type is not a state or province, an abbreviation of the unit-type
is usually appended; e.g., "Dist." for District, or "Pref."
for Prefecture. A trailing wildcard (%) is automatically appended to any entered
- A simple text box. The name of the tertiary political
unit -- i.e., county, parish, district, etc -- when known. Most names in this
field have an abbreviation appended indicating the type of political unit;
e.g., "San Francisco Co.", "Shannan Pref.", etc. A trailing
wildcard (%) is automatically appended to any entered value.
- Island Group
- A simple text box. for the name of Island groups (e.g.,
"Andaman Ids."). A trailing wildcard (%) is automatically
appended to any entered value.
- A simple text box. for the name of an Island (e.g.,
"Mindanao Id."). A trailing wildcard (%) is automatically appended
to any entered value.
- Elevation Fields: min - max
- Simple numeric inputs enable specification of an elevation range; i.e.,
lower (min) and upper (max) bounds. Ranges can be open-ended (one of the fields
- The textual description of where the specimen was collected; often includes
one or more references to a named place and an offset -- direction and distance
from the named place. The contents of this field are full text indexed and
can be searched for a single word or phrase; e.g., "Carmel" or "Carmel
Specimen Identifiers, Characteristics, and Collection
- A single-select listbox.
- Life Stage
- A single-select listbox. The values used in the database are as follows:
||fertilized or unfertilized; not yet hatched
||in live-bearing species before birth; usually isolated by dissection
||between hatching and metamorphosis
||with an adult-like body form (not larval), but smaller and sexually
|between juvenile and adult
||fully grown and/or sexually mature
- A checkbox. The checked state limits query results to
specimens that have associated tissue samples.
- Museum (abbreviation)
- A single-select listbox. The values are:
||California Academy of Sciences
|CAS Stanford University (Amphibians)
||CAS Stanford University (Reptiles)
- Catalog Number
- A simple text box. All catalog numbers are integers.
A single value or an inclusive range of values can be entered. Wildcards are
- A simple text box. Collector names are formatted with
initials first (when known) then last name; e.g., "J.R. Slevin"
or "J.R. Slevin and E.S. King". The search will automatically append both leading
and trailing wildcards; e.g., entering "Slevin" will search for "%Slevin%".
- A single-select list box. Indicates the preservative
in which the specimen is currently stored. Values: Alc - alcohol (ethanol);
C&S - cleared and stained; Dry - dried skin or skeletal material; Form
- Collector's Number
- A simple text box. Collector's numbers are typically
parsed into a prefix and an incremented identifier -- typically an integer,
but sometimes alphanumeric. Both the prefix and "number" are stored
and searched as strings; wild cards are allowed. Results are displayed with
a hyphen (-) separating the prefix and "number". In rare cases,
a hyphen is contained as the last character of the prefix.
- Year Collected
- A numeric interval selector; can be used to specify: 1) a single year, 2)
the upper or lower boundary (inclusive) of an open ended range of years, and
3) an inclusive range of years.
||Collected in 1950
||Collected in 1966 or later
||Collected in 1906 or earlier
||Collected between 1970 and 1979 (inclusive)
- Page Style - Multiple Pages/Single Page
- A pair of radio buttons.
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
- A pair of radio buttons. 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.
