Predictiv Index of Biotic Integrity of running waters in Iran
Abstract
Development of a predictive Index of Biotic Integrity for running waters of Iran Iran is the second largest country in Southwest Asia and covers multiple ecoregions, different climatic regions, and considerable fish diversity. Man's activities had profound and usually negative influences on freshwater ecosystems. Current efforts to evaluate effects of man's activities on aquatic ecosystems have been attempted to use chemical/physical water quality parameters and macroinvertebrates. These indicators do not fully reflect human disturbances, in particular hydromorphological pressures and continuity disruptions. Therefore, in this project we will focus on fish as an additional indicator based on the assumption that human pressures have significant effects on the distributions of fish species and hence alter the composition and structure of fish assemblages. First, we review the fish ecological situation and identify main ecological requirements and guilds of Iranian fish species. We then compile a database of fish species distribution using historic records and reports, maps of species distribution, actual records of species occurrence and actual samplings of fish assemblages. After that we develop country-wide presence/absence models for fish species and ecological guilds for undisturbed reference conditions using environmental factors. In order to analyse the pressure-specific response of fish communities to human alterations, test catchments in different ecoregions are selected. Field samples of fish communities are compared with the expected undisturbed conditions predicted by the reference models using different types of metrics. Finally, responsive metrics are integrated into a multi metric Index of Biotic Integrity for running waters of Iran. This will be the first large scale and country-wide IBI in Asia.
