- W4312740574 abstract "Waterbirds as an ecological indicator for monitoring wetlands : an application to Tunisia. We propose a simple ecological index to monitor wetlands, based on interannual changes in waterbird numbers and the hydro-ecological characteristics of their wintering sites. This new method provides a simple tool applicable to most types of wetlands in northern Africa with comparable waterbird species and hydrological attributes. Scores of this ecological index are calculated through a four-steps approach : (1) discriminate prospected sites into different associations based on their hydro-ecological characteristics ; (2) compute indicator values for each waterbird species considered to quantify the strength of species-habitat relationships in each wetland associations ; (3) calculate the relative rate of temporal change in indicator species abundances between two sampling events (in our example 2001-2013 and 1970/ 2000) ; (4) compute the weighted sum across species of the product of these two metrics within a given wetlands association. The application of our index to the monitoring of Tunisian wetlands suggests the degradation of wintering lagoons and salt pans and coastal environments. Nevertheless, applying the index in floodplains and garaets tends to indicate improved overwintering conditions, especially for man-tolerant waterbird species. Our new index targets environmental stakeholders seeking for an efficient tool for biodiversity monitoring." @default.
