 Introduction  Overview Literature based Analysis and Assessment Tool –

LiACAT

 New developments in LiACAT  Quantification of anthropogenic impacts  Application of model results for the BSII and for the

quantification of environmental targets

 Examples

Content

Assessing the status of different ecosystem components

 Literature data input forms,

which can be customised

 Spreadsheet form for

getting a quick overview

 Special input option for

relationships

 Possibility to filter

information by setting topic specific tags

 Visualisation of relation-

ships and cumulative effects with a Sankey diagram

The LiACAT tool

 As a new module, the WebPlotDigitizer is implemented and can

be used within LiACAT. With this module, raw data can easily be extracted from graphic presentations in the publications and be imported to LiACAT

New developments in LiACAT WebPlotDigitizer

 Uploading of geographical data such as species distribution data

can now be uploaded and be visualised on a map.

New developments in LiACAT Geographical Toolkit

 Special features:

interpolation, functions for simple calculations and mapping of monitoring stations

 The new Sankey diagram will allow to show literature

information in a clear way for a chosen level of detail, while it will still be possible to access the detailed information by a very user-friendly zoom-in function

New developments in LiACAT New Sankey diagram

 An additional, new type of matrix is being implemented

specifically focusing on the analysis of interaction effects

New developments in LiACAT Interaction effects

Quantification of anthropogenic impact based on literature analyses

Biochemical effect Intensity of pressure Physiological effect Biochemical effect Population effect Physiological effect

x % decrease of population size

 Expample for a comparison of predicted change with

environmental targets

Application of the method for the quantification of environmental targets

“to restore populations to, or maintain them at, 80% or more of carrying capacity” (ASCOBANS, 1997) Predicted population size for a pressure scenario for 6 years based on present monitoring data

 Application of the method for selected ecosystem components  Combination of the results from the expert questionnaires and

• ther literature analyses by transferring the results into

categorical data

 Ranking of the pressures  Comparison of the results from different analyses  Visualisation of the complex pathways and impact chains (input

for the report?)

 Test of management options

Application of the method for the BSII

 We extracted about 150 datasets from publications so far to

quantify relationships including mainly effects related to seagrass meadows but also to blue mussels

Example seagrass meadows

Output: % change and corresponding environmental status Input: Pressure scenario or monitoring data

Example blue mussels

Cumulative index value between

• 1 and 1

In this example:
