Ecological characteristics of the reproduction of the nyroca duck (<em>Aythya nyroca</em>) breeding in lake Tonga (Northeast of Algeria)

Abstract

The habitats and ecosystems of the Mediterranean Sea are of prime strategic interest both ecologically and economically. The Ferruginous duck, a species widely distributed in Africa, Europe and Asia, these numbers have experienced declines and changes in distribution in recent decades. The primary reasons for these declines are mainly due to habitat degradation and loss and hunting for local consumption .
