20 Annex 6: Software technical report Technical background An analysis of IT technologies identified that the best solution for the software tool was a web-based information system managed by Apache 2.0. Pages and input formats were mainly built with XHTML and were embedded using JavaScript and XML. Processing data, for entering, validating, homogenising and identification of errors was made using by PHP 5.2. Some internal checking files were managed with MySQL as guilds tables, abbreviations and codes. Annex 6- Figure 1: Tree layers scheme of the application The web page is adapted for the main web navigators (Firefox, Explorer 7 and 8) and the iphone, it has been made according to XHTML 1.0 Transactional W3C rules. The advantages of this software implementation are: Users can access the EFI+ software by standard web-navigator from different platforms and operating systems. The Web Server holds the common files required for checking and calculating. The system allows the use of R-project for Statistical Computing (v and v.2.7.1). The web application is composed of two modules: an application made in PHP language for entering data and the statistical code written in R language for obtaining metrics, scores and the final EFI+ index. Once data are entered and sent to the server, a fractionated process begins. Firstly data are filtered by PHP routines where data are checked to avoid bugs, mistakes and gaps. In the case of qualitative variables, records are checked against possible categories, whereas numeric variables are checked against a confidence interval and frequently it is only to check as positive value. The software is able to handle the existence of no data. In such cases the value is recorded as a code that means No data (the common database item null), consequently for character type data it should be NoData, for numeric data (integer and floating) it

21 should be The PHP application fixes some small mistakes and fills in some predictable gaps but the user has to change any records identified as wrong by the data filters.. After completing and checking all data, the PHP-code builds an ASCII comma separated value file (csv), called Input.txt, and triggers the R code. The Input.xls is fulfilled by the user at the beginning of the procedure. The Input.xls is checked and corrected if necessary by the user. The EFT types are computed for each fishing occasions by the software and will be included in input.txt. Input.txt is the file used for the computation of the expected values and scores values by R. The output.txt is the file provided by the R application and used by PHP application to get the final output for user PHP code reads output.txt and provides an available Excel file. Annex 6- Figure 2: Simplified information flow through data files and code-scripts. Once the PHP-code triggers the R-code then input.txt and diadromous.txt are loaded and all necessary data (observed data, expected data, scores and index) are calculated by the R code. Observed data contains the sampled metrics, expected data contains the expected values of metrics according to the models made with calibration sites, in scores are written the residual values and the last section contains the final indices. Finally these four data sets are put together in the file output.txt and an incidence file (info.out). These files together with a structured file system are needed to run the EFI+ R software: repository files as fauna.txt and environ.txt, R core and routines scripts (models, lengthmodels, geomodels, guild, stdpack, lengthstdpack).

22 Annex 7: Index development Dataset description The initial database contained sites corresponding to sampling occasions distributed in 15 countries: Austria, Switzerland, Germany, Spain, Finland, France, Hungary, Italy, Lithuania, Netherlands, Poland, Portugal, Romania, Sweden and UK. For the index development, only one sampling occasion per site was considered and sites for which data were incomplete were excluded. The final working database contained 9948 sites, from which two specific datasets were defined: The first dataset corresponds to the slightly disturbed sites (SID, N= 2526) that represent no or a slight degree of perturbation (selection based only on the pressure variables). This dataset was used to explore, and to test, the response of metrics among ecoregions in the «quasi» absence of pressure. The second dataset was defined as the calibration dataset (CD) (included within the SID) and was used to model the metrics. The selection process of the calibration site was relatively strict and was extended to the effects of pressure (i.e. modification of the hydrological regime). In addition, only sampling occasions where the number of fish caught were greater than 50 individuals were retained in the analysis to reduce the potential effect of the sampling effort on the assessment of assemblage structure. Finally, site selection was completed by the exclusion of neighbouring sites to limit spatial autocorrelation and by a sub-sampling procedure to balance the representation of calibration sites located different regions of Europe (reduce the influence of the large number of calibration sites in the North of Poland, in Romania and in the North of Spain [e.g. Galicia and Asturias]). Following these selection criteria, 533 calibration sites were retained to model the metrics, representing only 5.3% of the initial dataset. Such a strict selection process was essential to obtain an unbiased calibration dataset and unbiased models. Modelling process The metrics were modelled by generalised linear modelling (Nelder Wedderburn 1972, McCullagh & Nelder 1989) and a stepwise procedure based on Akaike Information Criteria (AIC, Venables & Ripley 1999). This approach was considered to be a good compromise between over-fitting of models and final predictive error. The metrics based on the species number were modelled by a Poisson model with logarithmic link whereas a negative binomial distribution was used for models based on fish number because fish abundance data are largely over-dispersed. An offset parameter was systematically used to impose a baseline corresponding to total richness or total number of fish (e.g. McCullagh & Nelder 1989, Cameron & Trivedi 1998). The environmental variables used to model metrics integrate several aspects of river characteristics such as morphology and climate. Six environmental variables were selected: actual river slope (log-transformed, m/km), average July temperature ( C), Thermal amplitude (Tdif=Tjul-Tjan, C), natural sediment (coded in 3 categories) and two computed variables based on linear combination (Principle Component Analysis) of geomorphological variables. In addition, a specific weighting stratified by Strahler order and ichtyoregions (Reyjol et al. 2007) was applied to reduce the unbalanced spatial organisation of the calibration dataset.

23 Orthogonal polynomials (of degree 2) were calculated for river slope and average July temperature to account for the non-linear response of metrics to these environmental variables. Model selection The model selection process was based on two main steps: The first selection step was based on simple criteria, such as the structure of modelling residuals, and good adjustment of the fitted value enabled the reduction of the number of models selected. This first screening was essential, as for each modality of a given ecological trait, more than 5 different metrics could be computed (e.g. binary, count proportion data based on species number and count and proportion date based on fish number). The second selection step involved the consideration of more complex criteria. The selected models are characterised by a satisfactory stability, satisfactory agreement between expected and observed values, low residuals structure and quasi-normal residuals distribution. The consideration of these criteria is strongly required to increase the extrapolation capacity of models and to limit the bias of predictions based on environmental conditions outside of the calibration environment. After a few conservative and strict modelling processes, the number of candidate metrics retained was relatively low. Only 13 metrics were retained: five metrics based on species number (Ric.O2.Intol, Ric.Hab.Intol, Ric.Hab.RH, Ric.INSV and Ric.RH.Par), four metrics based on fish number (Ni.O2.Intol, Ni.hab.Intol, Ni.INSV and Ni.LITHO) and four metrics based on the number of individuals with a total length of <150 mm (Ni.O2.Intol.150, Ni.Hab.Intol.150, Ni.RH.150 and Ni.INSV.150). Metric selection Three criteria were used to select metrics: - Correlation between metrics - Pearson coefficient < 0.70, - Representativeness of the metric in the different ecoregions. - Sensitivity of the metric to the index of pressure In some particular ecoregions and/or countries, species belonging to some of the candidate guilds were never abundant, even in undisturbed sites. This was particularly the case for the cyprinid river type and eastern or Mediterranean regions. Several tests and previous analysis demonstrated that in such situations, the score was always underestimated for sites belonging to the lowest pressure group: the median value of sites was not close to 0.80, as for other metrics, but was below 0.50 and the score of all sites, whatever the level of human disturbance, was always underestimated. In all cases, the metrics based on the guild of insectivorous species were insensitive to pressure. In the salmonid river type, the most sensitive metrics were based on oxygen depletion and habitat intolerant guild species, and were expressed in relative abundance of individuals. The two corresponding metrics considering both the size classes were highly correlated (Ni.O2.Intol and Ni.Hab.Intol.150). Among the metrics expressed in term of abundance of small-sized individuals, the two metrics based on these species guilds are also

24 highly correlated (Ni.O2.Intol Ni.Hab.Intol.150). In order to not use the same guilds with two different metrics, and following complementary evaluation of metrics responses, only the two following metrics are selected: For the cyprinid river type, the metrics based on oxygen depletion and habitat intolerance could not be used due to their lack of representativeness in several ecoregions. Among the others and considering the high correlation between Ric.Hab.RH and Ric.RH.Par, only two metrics were retained. Ric.RH.PAR was preferred to Ric.Hab.RH due to its higher relative abundance in undisturbed Mediterranean sites. The metrics finally selected were: Salmonid river type: Cyprinid river type: Ni.O2.Intol and Ni.Hab.Intol.150 Ric.RH.PAR and Ni.LITHO Annex 8-Table 1: Parameters associated with the four metrics selected. The term 'poly' indicates that orthogonal polynomials of degree 2 were used (e.g. Venables & Ripley 1999). Performance metric Ni.O2.Intol Ni.Hab.Intol.150 Ric.RH.Par Ni.LITHO (Intercept) poly(tjul, 2) poly(tjul, 2) poly(lslope, 2) poly(lslope, 2) natsedmedium natsedsmall syngeomorph syngeomorph Tdif To quantify the performance of metrics for detection of altered sites, the slightly disturbed sites were characterised as unexposed sites, and the sites classified by pressure index as 4 and 5 were characterised as exposed sites. A specific dataset which integrated previously described limitations of index was required to reduce the potential bias induced mainly by misclassification of the river zone for individual sites. Under the hypothesis that the pressure index was an acceptable measure of the extent of site alteration, we observe that the indices, particularly in the cyprinid river type are characterised by low sensitivity and high specificity. In spite of low sensitivities, it was noted that the measures of specificity (spec) and positive predictive (ppv) are relatively high in the cyprinid type (spec=0.89 and ppv=0.78). The less significant results in the salmonid river type (spec=0.93 and ppv=0.54) can be explained by the low prevalence of pressure (= exposed sites, prev=0.16). Both indices were optimised to recognise un-degraded sites in most cases. Consequently, the detection of an altered situation efficiently confirms the high degraded level of a site. From an economical/management point of view, this objective corresponds to the idea that the risk for managers to invest in restoration measures at un-degraded sites is low.

25 Error estimation To estimate the predictive error associated with individual and global fish bio-indicator scores, a hybrid approach based on three elements was used: i) theoretical knowledge on generalized linear model (GLM), ii) simulation procedure and iii) principle of the error propagation. For one single metric, the model provides expected values and standard errors. By extending the classical regression propriety, a random sampling procedure based on normal, expected values and standard errors produces an empirical distribution of the expected values in the link space. After the inverse link transformation, the computation of the standardized distance between the quantile values (e.g. 0.1 and 0.9) and the observed values provides a good approximation of the predictive intervals. For the metric based on species with preference to spawn in running waters (Ric.RH.Par), we observe that the size of 80 % tolerance intervals are close to 0.39 units (+/ units). For the metric based on lithophilic fish (Ni.LITHO), the tolerance interval appears to be larger and was close to 0.42 (+/ units). The estimation of predictive error for both indices was more complex because it involved the addition of non-independent variables. For the cyprinid index for example, the correlation between Ric.RH.Par and Ni.LITHO was equal to Consequently, the computation of theoretical variances is extremely complicated. To reduce these difficulties, the previous results were generalised and an adapted simulation strategy to estimate empirical distribution of aggregated scores was adopted. At each step, an empirical value from normal distribution based on expected value and expected variance for each metric was computed and the new scores were calculated. Following this step, these values were aggregated to obtain the final indices. The consideration of quantile values (e.g. 0.1 and 0.9) easily completes the construction of the tolerance interval. For the cyprinid index, the size of the 80% tolerance interval was close to 0.30 units (+/ units, Figure 1). This corresponds more or less to one quality class. The error estimation method presented here should only be considered as an experimental approach and requires some additional tests before implementation in the software tool for calculating the new EFI+.
