Checklist - A list of the scientific names of the species in a particular
Taxonomic group, often with references to the literature and previous
names. |
| DAFOR |
An acronym for the abundance scale Dominant, Abundant,
Frequent, Occasional, Rare. MapMate adds P for Present and V for Very
Rare. |
| Hectad |
A square 10 kilometers by 10 kilometers on the National Grid
(100 square kilometers in area) often used as the unit for mapping in
National Atlases. Often referred to as '10km squares', see also Tetrad.
(for completeness; a 5x5km square is apparently called a Quadrant (four to
a Hectad: used in some Continental mapping schemes) and a 1x1km square is
a Monad) |
|
Hypertext |
A system of text in a computer document in which clicking on
specially marked parts of the text automatically transfers you to a related page
or document. Examples of hypertext are World Wide Web pages and Windows Help
files |
|
Match List |
When a part of a name that you have entered into a Data Entry field will match more than one entry in the associated table the matching values are shown in a list (Match List) for you to select the correct one. Where you always select the same item from a Match List you can right-click on it and select 'Remember this' from the menu that appears so that item is always selected, and added to your
Training List. |
| Phenology |
The study of the times of (often first or last) occurrences
of species in the year |
|
s.l. or sens. lat. |
After a Taxon name an abbreviation for sensu latero, "in the broad sense" of a name. Usually applied when a Taxon has been split and any specimens identified before the split are referred to as s.l. as they could be either species. If the Taxon is definitely identified as the species with the original name it is referred to as sensu stricto. e.g. records of the Copper Underwing Moth made before 1968 would be Amphipyra pyramidea s.l. as the species could have been Svensson's Copper Underwing Amphipyra berbera svenssoni, which had not yet been described. Subsequent records (or specimens that have been re-examined) would be Amphipyra pyramidea s.s. |
|
s.s. or sens. str. |
After a Taxon name an abbreviation for sensu stricto, "in the strict sense" of the name; see also s.l. |
|
SQL |
Structured Query Language; a standard programming language used to write Queries to extract specific data from SQL-compatible databases |
|
SRS |
Abbreviation for Spider Recording Scheme, run by the British Arachnological Society; Web Site:
www.britishspiders.org.uk MapMate includes extra Habitat and Micro-habitat details for this Scheme |
|
Synonym |
In taxonomy the term Synonym is used to mean a previous name for a Taxon where then has been a change to its scientific name. In MapMate an 'equals' ('=') sign before a Taxon name signified that it is a Synonym. You can find the later name by clicking on the
'Taxon' menu in the 'Data Entry:' form and selecting 'View this Entry...'; this opens the 'Taxa: View' screen and the current Taxon name used by MapMate (for mapping) will be shown in the
'Refers To' field. |
|
Taxon |
A general term for a unit of Biological Classification. The term 'Taxon' (plural Taxa) is often equivalent to 'Species' but is used instead as it can refer to a sub-species, or it could be the name for an aggregate of species that cannot be easily separated. |
|
Taxonomy |
The study of the classification of living things. |
| Tetrad |
| A square 2 kilometres by 2 kilometres on the National Grid (4 square kilometres in area) often used as the unit for mapping in County Atlases. There are 25 Tetrads in a
Hectad (10 kilometres by 10
kilometres) and they can be entered into the 'Grid
Ref' field of the MapMate Site table using the so-called DINTY system where the Tetrads are given letters starting from the bottom left working up and across, so the most north-westerly Tetrad in the SW41
Hectad would be SW41E. |

Training List |
When an abbreviation in a Data Entry field gives a Match
List and you always select the same one you can right-click on the correct
item and select 'Remember this', the abbreviation is then added to your
Training List. |
| Vague Date or Date Range |
You can enter a date range by putting the word "to" between the start and end date e.g. "10 Jul 1999 to 20 Jul
1999" (click here). |
|
VC |
An abbreviation for Vice-County |
|
Watsonian Vice-County |
Vice-Counties are a system devised by the botanist H.C. Watson (1804-81) of dividing the British Isles into approximately equal areas based on Victorian County boundaries (e.g. Yorkshire is split into five Vice-Counties). The system was extended to cover Irish Vice-Counties, their numbers are preceded by the letter 'H'. Many early distribution records use the Vice-County system and current mapping schemes often use the Vice-County as a cross-check on the Grid Reference. Unlike modern Administrative Areas, the boundaries of Vice-Counties are not subject to change by politicians. In MapMate lists County names refer to modern Administrative areas and Vice-Counties are represented by their standard numbers, e.g. if in selecting an area or region for a Base Map you choose "Berkshire" the map will be of the modern Administrative County of Berkshire, but if you select the number "22" from the list the map will be of the original County of Berkshire before recent boundary changes. |
|
If you need to look up the number representing a Vice-County you can do so in MapMate from the 'Analysis > 'Browse tables' > 'Browse Vice-County' menu. |
