Date of creation:
29.05.2007.Scale:
1:20 000 000.Accuracy of the map:
It is created on materials of maps of natural scale 1: 10 000 000 and on literature data.Projection:
"Alber's Equal Area Conic for the USSR", 9, 1001, 7, 100, 0, 44, 68, 0, 0.Basic content:
Vector map. Area of distribution is shown by polygon (main distribution) and by dots (sporadic distribution).Accuracy of the classifier:
Area of main and sporadic distribution is shown.Method of map production:
The area of distribution is established according to the analysis of the open-published maps and literature. A map compiled by Hulten E. & Fries M. (1986) is taken as a prototype. Distribution of C. jacea in the European part of the USSR is supported by the literature data (Taliev, 1935; Maevskii, 1954; Tolmachev, 1962; Shishkin, 1965; Minyaev et al., 1981; Prudnikov & Poluyanov, 1996; Shlyakova, 1982; Bakin et al., 2000; Grigor.evskaya, 2000; TSvelev, 2000; Rodionova, 2001; Shmidt, 2005). It is a common species in Ciscaucasia (Galushko, 1980), Transcaucasia (Grossgeim, 1949), and Crimea (Rubtsov, 1972). C. jacea grows in Cis-Ural (Shishkin & Grubov, 1966), being brought to Siberia (Malyshev & Peshkova, 1979; Krasnoborov, 2001). The zone of weediness is not shown on the map as the weed litters mainly crops of perennial grasses and winter cereals with abundance at most 2 points.Reference citations:
