The Plant Species Data Fields

The plant species entity contains taxonomic, morphological, and ecological ("ecomorphic") data for each species of plant. In addition to the Data-Entry Authorization section, each species entry must be associated with at least one reference (which requires the fields ref.author_1 and ref.date). See Reference Data Fields. 

Required fields for a plant species consist of:

Genus                         psp.genus          
Species                       psp.species        
Unique field                  psp.unf            
Data Coordinator              sau.coordinator    
Data Authorizer               sau.authorizer
Higher taxonomic information should be supplied for any genus that is new to the database. Later entries of congeneric species will be automatically supplied with the higher taxonomic information by the software, so it is not necessary to provide it in these cases. The taxonomic classifications used for plant species in the ETE database were obtained primarily from The Plant-Book (Mabberley, 1989).

Conductivity

The conductivity value for fossil wood.

 

DATA TYPE

 A real number (with optional decimal point).

 The estimate of conductivity capability for fossil wood, given by the formula below. Conductivity capability (C) describes the amount of water that can be transported, and represents the water needs of a plant. It is calculated as:

 

 

where r = the mean or average vessel radius and D = the mean or average number of vessels per mm2. See Wolfe and Upchurch (1987).

 

According to Wolfe and Upchurch, "the highest C values are typically found in large trees. Indeed, C values >200 are found almost exclusively in medium-sized or large trees, and C values >500 are known only in large trees. These relations prevail in woody plants of both humid and dry habitats."

DATA TYPE

 A character field not exceeding 25 characters. MANDATORY FIELD.

 

DESCRIPTION

 The name of the member of a research group who authorizes the entry of information into the database. This may or may not be the same as the Data Coordinator. It is intended that the currently empowered Authorizers be a small and restricted set of research group members who work closely with the database. Their job is to certify that the data prepared by the Data Coordinator(s) meet the current standards for scientific accuracy and have been entered logically. They are also responsible for catching major errors of a scientific nature, inconsistencies, and misunderstandings on the part of whoever filled out the datasheet. No datasheet can be entered without an Authorizer.

Data Coordinator

The name of the researcher preparing the data for entry.

 

DATA TYPE

 A character string not exceeding 25 characters. MANDATORY FIELD.

 

DESCRIPTION

 The data for each entity are prepared by or under the supervision of a particular researcher (or group of researchers). This (these) person(s) is designated the Data Coordinator, and is the primary source of the information and is responsible for its accuracy. Data Coordinators may or may not also be Data Authorizers. Data Coordinators possess such rights over the data as the Consortium has decided in its general policy on the subject. Briefly, for entities designated as "private", the Data Coordinator's data are treated as a collection that the Data Coordinator is actively working on. Thus, the Data Coordinator must be consulted/informed when other researchers use the data in some project intended for publication. The Data Coordinator may deny permission for such use. The Data Coordinator may initially or at a later time designate the status of a species or locality as "public". In this case, the data become "public domain" and can be used by anyone with access privileges to the database, for any purpose, without informing or obtaining permission from the Data Coordinator. The Consortium has established a time period (5 years from date of entry or last modification) after which data of a particular entity will convert to "public" status, unless there are compelling reasons to retain private status.

 Seed size, expressed as estimated mean seed length, seed width and seed height (mm). All three measures do not have to be specified; ultimately, the point of having the complete (orthogonal) three would be for calculation of estimated seed volume. However, only one or two measures may be available. The best convention would be to enter the longest seed dimension as length, and (if available) the second largest as width, and the third as height.

Species

 The species epithet of the species.

 

DATA TYPE

 A character field not exceeding 30 characters in length. MANDATORY FIELD.

 

DESCRIPTION

 The species name of the species. It is always entirely in lower case. Species may also be recorded as "sp.", "indet.", or preceded by "cf." to indicate different levels of uncertainty in assignment. These three strings are the only ones that the graphical interface recognizes as alternatives to Linnean names. "sp." implies that it is known that this is a new or separate species, but that it currently has no formal taxonomic name; use "indet." for a species that is not identifiable at the species level. "cf." is to indicate any of the many tentative assignments (including "aff.", "near", ? species, etc.). "cf." entries always are recorded as separate species, not as instances of the referred species.

Status

 The current status (public or private) of a species record.

 

DATA TYPE

 A predefined character string not exceeding 15 characters in length.

 

DESCRIPTION

 Every species or locality record in the Database at any moment is assigned a status, which indicates the level of access permitted to that record. Currently, the value "public" indicates that the record is essentially "public domain" and will be made available without restriction in the public domain version of the ETE Database. The value "private" indicates that the record will be accessible only to those researchers who have access to the ongoing working database. Records will ordinarily be entered with "private" status until the members of the Project (q.v.) that has generated them releases them to the public. The Data Coordinator (q.v.) for each record is ultimately responsible for any changes of its status. Additional values for status may eventually be added if it becomes necessary to specify in finer detail the access level of an entity.

 psp.status

 

ALLOWED VALUES

Unique

 Makes the species entry unique.

 

DATA TYPE

 A character field not exceeding 30 characters in length.

 

DESCRIPTION

 At times the occurrences of the same species at different localities will still differ in some ecologically meaningful way. For example, the same named species may be of substantially different size in different fossil localities. In order to record the size appropriate to each locality, one must somehow separate the two species occurrences -- as if they were two separate species. At other times, adequate identifications may be unavailable, or systematic work needs to be done, such that the best one can do is to identify to some higher taxon (e.g., Somegenus sp.). In such a case, "Somegenus sp." is what the computer will search on when a species list is entered. But there may be many undescribed species of Somegenus, each different in ecologically meaningful ways, and found in a variety of localities. Yet, they all have the same generic and specific name as far as the computer is concerned. They need to be treated individually.

 

The unique field is the way to do this. In addition to Genus and Species, this field is also searched when a species name is input as part of a species list. In effect, the ETE Database uses "trinomial" designations for its "species". Thus, to separate occurrences of Somegenus, all one has to do is to specify an entry in the unique field. It might be a letter or a number, or an abbreviation for a locality, or any string of 30 characters or fewer that will serve to identify it uniquely. Remember that other people might be working with Somegenus as well, so naming a species "Somegenus sp. A" (i.e., the unique field = "A") might inadvertently identify it incorrectly as another one already in the database. One fairly safe solution would be to include some kind of locality, regional, or temporal designations within the 30-character string -- increasing the probability that the unique field will really be unique.

Data Coordinators must keep track of their own usages and assignments using this field, and they should become aware of the ways in which the species (or close relatives) that they are working with may have already been entered by other workers. The computer cannot sort out a nomenclatural mess where two different things have been given the same name by mistake. On the other hand, excessive use of the unique field, resulting in a situation where all or most occurrences of a species are distinguished as unique, should also be avoided. This is surely unnecessary, takes up valuable storage space, and can also become confusing to other workers.

There are, however, a number of common situations that require the use of the unique field for a plant species. These include cases where some plant species lack a formal taxonomic name, although they can still be traced from locality to locality. In order to preserve this distribution information, it is recommended that information connoting the uniqueness of the species be entered into the unique field associated with the taxonomic data. The following unique field identifier is recommended as a standard to be used for the plant species unique field so that each will be given unique labels: [locality name][year of publication][first initial(s) of last name(s) of author(s)][plate and figure number(s)]. The format for denoting plate and figure numbers is p##f## where p=plate, f=figure and ##=numbers/letters of plate figure. It is important to remember that this unique designator should retain its significance for an unnamed species. Therefore, a person collecting information for the database should check other referenced localities for unnamed species to determine if a unique designator is needed or if the species has already been referenced with another unique name. (Note: When a specimen has not been published, the standard museum abbreviation and the specimen number substitute for the author name, year of publication, and plate and figure numbers.)
