Abstract
We investigated the odonates of Wadi Cherf, a tributary of Wadi Seybouse, and explored the main environmental factors that may be important drivers of the abundance and diversity of Odonata assembl...
Highlights
The complex life cycles of Odonata link aquatic and terrestrial communities (Corbet, 1999; Remsburg & Turner, 2009) and their ecological requirements have made them key indicator species of the quality of freshwater ecosystems and the management of aquatic biodiversity (Bried & Samways 2015; Samways, McGeoch & New, 2010)
In the last two decades, considerable attention has been devoted to increasing our knowledge of the distribution of Algerian odonates (Boudot et al, 2009; Samraoui & Corbet, 2000a; Samraoui & Menai, 1999)
Though useful, are biased and incomplete as relatively pristine habitats may have been left out of such surveys. This is the case for the River Seybouse where previous studies of the main affluent, Wadi Cherf, have only been carried out in a small number of sites (Khelifa et al, 2011; Yalles-Satha & Samraoui, 2017)
Summary
The complex life cycles of Odonata link aquatic and terrestrial communities (Corbet, 1999; Remsburg & Turner, 2009) and their ecological requirements have made them key indicator species of the quality of freshwater ecosystems and the management of aquatic biodiversity (Bried & Samways 2015; Samways, McGeoch & New, 2010) Knowledge of these ecological requirements has been turned into a useful tool for the evaluation of the overall conservation status of aquatic environments and wetland bio-monitoring (Steward & Downing, 2008). Little is known about the odonates of the upper reaches of the River Seybouse These past studies date back about one decade
