Journal Title: Current Trends in Natural Sciences - Year 2017, Vol 6, Issue 11
Abstract
In this paper, the authors show the results of their research on the species of Anseriformes, performed on the dam lakes between Vâlcele and Goleşti from the Argeş River during February 2013 – January 2014. The Anseriformes was one of the two overdominant orders of the avifauna from the mentioned period. It numbered 15 species, which were represented by 49,335 individuals. There were 5 euconstant species (Cygnus olor, Anas platyrhynchos, Anas crecca, Aythya fuligula, and Aythya ferina), and 3 eudominant species (Anas platyrhynchos, Aythya fuligula, and Aythya ferina). The most individuals were observed in October – November and the number of species was the biggest in January – February. In the vernal and aestival seasons the numbers of species and individuals were very low. Anas platyrhynchos was the best represented (22,599 individuals, over 45% of whole number of individuals), followed by Aythya ferina. As result, these are the overdominant species. Function of the natural local conditions and anthropogenic pressure, the Goleşti Basin was the most attractive for the birds and the Bascov Basin, the least.
