Coding systems for ecological parameters
For most purposes in community ecology research and freshwater ecosystem assessment, ecological information for taxa needs to be transformed into numerical values. Three different methods were used to code the information extracted from literature:
- Ten point assignment system: Most ecological characteristics of aquatic species cannot simply be coded as "yes/no". Most species, for example, inhabit several habitat types or utilise various food sources, and are
not highly specialised to a single habitat or food source. The ten point assignment system considers these gradients of habitats, feedings types and other relevant parameters and is based on the known (or estimated) average distributions, occurrences or behaviours of a taxon within the environmental gradient under consideration. The ten point assignment system was first used by Zelinka & Marvan (1961) for the classification of saprobic valences and was extended by Moog (1995) to other parameters, such as stream zonation preferences and feeding types. The ten point assignement system was used for coding the majority of parameters, which comprise several categories.
Example for the parameter "stream zonation preference": If 70% of a species’ records are observed in spring brooks and 30% in the upper trout region, 7 out of 10 points will be allocated to the category "hypocrenal" (spring brook) and 3 points to "epirhithral" (upper trout region) to describe the expected occurrence of this species within the longitudinal zonation of a river. For all other categories "0" will be used.
- Single category assignment system: The single category assignment system is used, if a taxon can be allocated to only one category of an ecological parameter. If the category applies to the taxon, "1" is assigned, if not, "0" is used.
Example for the parameter "temperature range preference": If a species only lives in cold water, then "1" will be assigned to the category "cold stenotherm", the categories "warm stenotherm" and "eurytherm" will get a "0".
- Presence/absence assignment system: The presence/absence assignment system is used, if a taxon can be allocated to more than one criterion/category of an ecological parameter.
Example for the parameter "altitude preference (WFD)": If a species occurs in an altitude range from 100 m to 700 m above sea level, then a "1" will be assigned to the categories "between 200 and 800 m sea level" and "below 200 m sea level" meaning that the species is present in these altitudes. For the category "above 800 m sea level" the value "0" is used indicating that the species is not present in this region.
Abbreviations
All abbreviations, which are displayed on the Result-page are explained on the Search-page. On the Result-page an explanation is available with tooltips. Just move your mouse pointer over the abbreviation and the full name will appear.
The following abbreviation table summarises all abbreviations used on freshwaterecology.info. It also offers explanations of individual parameters and categories, where available (this will be amended during the next months). The table can be sorted per organism group, per parameter, per category, alphabetically and it is also possible to filter for all entries.
