ABSTRACT. The data on size and spatial distribution of the settlements of red wood ants in two forests of the Novosibirsk region (NSO) and in the forest-park zone of Novosibirsk city are presented. In the NSO on the territory of the former reserve “Beryozovsky”, there are more than 400 anthills of Formica aquilonia Yarrow 1955 with a density of 14 nests/ha. In Novosibirsk Academgorodok in the large complexes of nests “Ant Forest” and “House of Scientists” there are more than 280 anthills of F. aquilonia with a density reaching 32 nests/ha. The predominance of small nests with a dome diameter of 35-100 cm and a spherical shape of a dome as well as rare budding indicates a weakened state of large complexes in urban environments. To preserve the unique supercolonies of, it is necessary to give the forest areas the status of a special protected natural areas as a myrmecological reserve.
KEY WORDS: ants, spatial distribution, supercolony, polydomy, urban environments.
