abstract
Support vector machines (SVMs) were used to predict the distribution of Azolla filiculoides (Lam.) in Selkeh ecosystem (northern Iran). Various structural-habitat and physico-chemical variables were used as inputs for the development of SVMs. First SVMs were tested with different folds cross-validation and then they were optimised with different exponents in order to find the best predictive results as well as a reliable prediction for Azolla distribution. The biotic variable consisted of cover percentage of Azolla in terms of 3 classes (low, medium and high). The quality of models was assessed using the percentage of Correctly Classified Instances (CCI %) and Cohen's kappa statistics (k). The results of the present study demonstrated that SVMs yielded the high performances to predict Azolla in the sampling sites. By attribute weights, SVMs provided quantitative correlations between ecosystem characteristics and the distribution of Azolla and accordingly allowed a be tter ecological understanding of the obtained results. The structural-habitat variables played a key role for the prediction than water quality ones. The depth of wetland and dissolved oxygen were the two most important explanatory variables in the study area. SVMs hence proved to have high possibility for decision-making in ecosystem restoration and conservation management program.
