Résumé :
|
Economic growth, demographic pressures, and lack of enforcement of environmental laws and protections have caused important levels of land-use changes and habitat destruction, threatening wetlands and their biodiversity around the world. Land-use changes have been the most important driving force on species composition changes in the last century. Mediterranean wetlands have been transformed by human activities over last the century and one-third of their surface area has been lost in the last decades. Understanding and quantifying the community-level responses to the land-use cover changes is essential for creating sustainable conservation management to protect species and ecosystems. The Gediz Delta is located in the Mediterranean basin of Turkey and offers the opportunity to understand better how agriculture and urbanization affect biodiversity with a good potential for generalization in other wetlands in the Mediterranean basin. This study's main objective is to better understand how land cover affects bird and reptile community assembly processes and which habitats in the Gediz Delta need special conservation attention. The study is divided into 3 components: First, we (a) evaluated the avian biodiversity changes in Gediz Delta from the 1980s-2019, and (b) compared bird and reptile communities in natural, agricultural, and urban environments. Finally, we (c) made a threat analysis and identified possible conservation actions for future management to reduce the effects of threats and improve the sustainable management of the delta.
