Date of creation:

10.08.2004.

Scale:

1:20 000 000.

Accuracy of map:

Map was created based on the following: the minimum territorial unit is regional (oblast) arable territories, which were selected by arable map, generalized to scale 20 000 000.

Projection:

"Alber.s Equal Area Conic for Russia" 9, 1001, 7, 100, 0, 44, 68, 0, 0

Basic contents:

Map is a vector file consisting of polygons and points. Points represent recorded locations of the species; polygons represent area of possible distribution of the species.

Accuracy of classifier:

Polygons are based on literature sources, political boundaries and ecological description. Point data were obtained from literature sources and herbarium specimens. Polygons are based on literature sources, herbarium samples, and field surveys by the authors.

Method of map production:

Historic agricultural statistics were reviewed at the level of agricultural region. The Former Soviet Union had 16 regions. The boundaries from the 1:4000000-scale map of arable lands were used to further refine crop distribution (Koroljeva et al., 2003). The following sources were also used to determined the map area of this species: State List (2004), Vehov (1978), Abramov (1974), Berson & Vitchenko (1990), Pyzhenkov & Malinina (1994). The species area within the USSR covers almost all of the arable territories since the species distribution is limited by the 60th degree of northern latitude (Matveev, 1985). The area selected takes into account climate zones of cultivation as proposed by Abramov (1974). The major sowing of cucumber in open ground is shown as a separate area (Pyzhenkov & Malinina, 1994). Places of cucumber cultivation in Central regions of Yakutia were presented as points (Recommendations, 1975).
