SPEARpesticides
2023.03
- Column Empirical added to table Taxa Traits & Classification to be able to manually overwrite calculated values for the SPEAR Class
- Columns Empirical SPEAR and References added to table Trait database
- Updated trait values with empirical values for the SPEAR class (taxa Crustacea Gen. sp., Diptera Gen. sp., Baetis sp., Megaloptera Gen. sp., Hydropsyche bulbifera, Hydropsyche incognita)
- Updated doc files to reflect changes
- Fixed some minor errors in the doc files. Replaced '>' by '>=' in classification rules for sensitivity and generation time.
2021.02
- German translation added for labels and documentation
- Updated quality classes with the following five levels:
EQpesticides | SPEARpesticides |
---|---|
High (I) | >= 0.8 |
Good (II) | >= 0.6 ... < 0.8 |
Moderate (III) | >= 0.4 ... < 0.6 |
Poor (IV) | >= 0.2 ... < 0.4 |
Bad (V) | >= 0.0 ... < 0.2 |
- Calculation of TUestimated changed to:
TUestimated = (0.17502 - SPEARpesticides) / 0.13012
- Updated normalization factor for SPEAR (NEW: 0.44, OLD: OLD 0.27)
For details see:
- Liess et al. 2021
- 'Determination of SPEARpesticides quality classes' in the Supporting Information of Liess et al. 2021
2019.11
- Fixed a bug in the log-transformation of abundance data (Correct: log10(4 * Abundance + 1) ). The bug was previously introduced in version 2019.10.
2019.10
- Renaming of the calculation file to 'SPEARpesticides' (OLD file name: 'SPEARpesticide')
- Updated trait table
- Changed log-transformation of abundance data ( log10(4*(Abundance+1)) )
- Updated normalization factor which is quantified as the averaged SPEAR-value for uncontaminated reference sites (NEW: 0.27, OLD: 0.31)
- Fixed bug in the classification rule for the SPEAR trait 'sensitivity' (NEW: trait value >= THRESHOLD, OLD: trait value > THRESHOLD)
- Class boundaries of EQpesticides are rounded to 2 decimal places
- Updated quality classes with the following five levels:
EQpesticides | SPEARpesticides |
---|---|
High (I) | >=0.98 |
Good (II) | >=0.76 |
Moderate (III) | >=0.55 |
Poor (IV) | >=0.34 |
Bad (V) | < 0.34 |
2018.05
- Updated calculation with normalized SPEAR values from 0 to around 1.

- Trait 'Migration' removed
- Trait 'Refuge' added
- Column 'Recovery' removed from calculation
- File extension changed to .indicate
- Updated url to online docs
- Updated quality classes based on the concept of the ecological status (WFD) with the following five levels:

---|---|
High (I) | >=0.976 |
Good (II) | >=0.764 |
Moderate (III) | >=0.552 |
Poor (IV) | >=0.341 |
