ECOLOGICAL RESEARCH ON AVIFAUNA FROM THE SITE NATURE 2000 ROSPA0062 – “LACURILE DE ACUMULARE DE PE ARGEŞ”. THE SEROTINAL SEASON

Journal Title: Current Trends in Natural Sciences - Year 2017, Vol 6, Issue 12

Abstract

The present paper provides the results of the ecological research conducted on the avifauna of the reservoirs located in the middle valley of the Arges River during the serotinal season. The serotinal season was one of the richest in species (we identified 169 species belonging to 15 orders, 45 families and 99 genera) as it is the season when the autumn agglomeration specific to migration is formed; 66 species are dependent on wetlands. We also performed an analysis of the avifauna based on ecological indices ((IR, constancy, dominancy, the Dzuba index of ecological significance, etc.). The Anseriformes, Passeriformes and Charadriiformes were overdominant. According to the dominance index and the Dzuba index of ecological significance, there were 5 characteristic species (eudominant and dominant): Anas platyrhynchos, Aythya ferina, Fulica atra, Phalacrocorax carbo and Larus ridibundus. The high number of subrecedent species (122 species) emphasizes a high fluctuation of bird species in the area under research, especially on the Goleşti Lake, also due to the fact that these lakes are on the route of the Rucăr-Bran migration corridor. We also notice in the serotinal season (as well as in the hiemal and prevernal seasons) the great importance of the reservoirs for birds. These reservoirs are immense stretches of water, whose value should be considered in correlation with their large valleys, where there are various agricultural crops and large areas of forest. This high habitat heterogeneity explains the presence of a high number of bird species during migration, even though there is a strong anthropogenic influence in the area under research. 33 species are enlisted in Annex 1 of the Birds Directive.
