Abstract
The geographic distribution of dragonflies in the Iberian Peninsula has been abundantly analyzed in recent years, though a vast area of the NW has been little studied to date. This paper presents the distribution of species of the Sympetrum genus (Odonata, Libellulidae) in the basin of the Duero River, Spain, where many variations in climate and orographic conditions are found. Six species have been recorded: S. fonscolombii, S. meridionale, S. sanguineum, S. striolatum, S. vulgatum and S. flaveolum. A generalized linear model with data of altitude above sea level, latitude, mean air temperature, and annual rainfall obtained in 25 sampling points showed that these four factors together explain the distribution of S. fonscolombii, S. striolatum and, above all, S. sanguineum. The distribution of S. meridionale is influenced by latitude and annual rainfall. In the area of study, the species S. vulgatum and S. flaveolum are associated above all with mountain zones.
