How to use the database
In freshwaterecology.info all macro-invertebrate organism groups, fish and diatoms are included. At present, there are two levels of access that offer different possibilities of queries:
- without login: taxagroups and countries can be queried
- with login: all available ecological parameters can be queried
If you want to become a testing member please contact Daniel Hering (daniel.hering@uni-due.de) and Astrid Schmidt-Kloiber (astrid.schmidt-kloiber@boku.ac.at) for your personal login.

How to query taxagroups and countries
Search
Taxagroup: Tick the checkbox of the taxagroup(s) you want to have displayed. You can choose more than one up to all ("Select all") taxagroups.
Country: Tick the checkbox of the country (countries) you want to have displayed. You can choose more than one up to all ("Select all") countries.
Option "Display only taxa occurring in all selected countries": displays only these taxa that occur in each of the selected countries.
Advanced search: offers you the possibility to search for a selected family, subfamily, genus or species. You can either enter the complete taxon ("equals"), the beginning ("begins with") or the ending ("ends with") of the demanded taxon name in the respective field.
You can also search for different identification numbers (ID-AQEM, AQEM/STAR shortcode, DV-Number, TCM-Code, Furse-Code, Perla-Code) by choosing one of them from the selection list.
Higher taxonomic units can be included, excluded or displayed exclusively by choosing the respective option.
Advanced display values: author or shortcode can be displayed by ticking the respective checkbox.
Tick the checkbox of the code that you want to have displayed. You can choose more than one up to all ("Select all") codes.

How to query ecological parameters
Note: For the availibility of ecological parameters see About the database.
Search
Example for the simultaneous query of two parameters (stream zonation preference, feeding type):
Tick - for example - the checkbox "Trichoptera" within the "Taxagroup"-selection. Tick the checkbox of the country (countries) you want to have displayed within the "Country"-selection.
Press the button "Ecological parameters" (only available if you are logged in). Select the ecological parameter that you want to query by ticking the checkbox left of the name of the parameter. If you want to have this (or another) parameter displayed within the "Results"-page, additionally tick the "display"-checkbox on the right hand side.
The database offers the possibility to query not only one ecological parameter but also two or more parameters at the same time.
Define the stream zonation preference (e.g.: all Trichoptera species living in standing water bodies and riparian zones of rivers indicated by 10 points within the "littoral"-field) and the feeding type (e.g.: no specification which means that all feeding types will be displayed) that you are interested in.
Parameters can be combined with an "or"- or an "and"-relation on the lower end of the site.

Results
The "Results"-page offers a list of only those Trichoptera, that are living in standing water bodies and riparian zones of rivers. Additionally the feeding types of those species are displayed. The parameter for which a criterion was defined in the query is marked in green.
Abbreviations are explained as tooltips.
