Figure 1.
Functional character measurements.
a) All measurements are standardised by the standard length. Caudal peduncle length is also standardised by body depth; caudal peduncle depth was only standardised by body depth; b) pectoral fin position: pectoral fin dorsal side distance divided by body depth at pectoral fin; c) eye position: eye–ventral side distance divided by body depth at the eye; mouth position: mouth–ventral side distance at the position of the eye divided by body depth at the position of the eye.
Figure 2.
Spatial distribution of human pressures.
We used the CORINE Land Cover data set and its land use classification as an artificialization gradient from natural habitat to urban habitat. Colors from green to red represent increasing pressures.

Results of species values of originality and specialization in a Cleveland’s dot plots in proportions (i.e. the sum of species values is one for each index).
Figure 5.
Spatial distribution of community specialization (CSI) and originality (COI) indices for 2005 (the years with the most sample stations).
Colors from green to red represent increasing index values.

Community indices response to land use artificialization with the CORINE Land Cover dataset.
Colors from green to blue represent increasing pressures.

Niche-COI response to land use artificialization across watersheds.
The Mix class is not represented because of limited sample size.
