Size and place in the construction of indigeneity in the Russian Federation.

Within the Russian Federation there are nearly 200 recognized "nationalities," approximately 130 of which could claim to be "indigenous." However, only 45 peoples are officially recognized as "indigenous small-numbered peoples of the Russian Federation" and thereby qualify for the rights, privileges, and state support earmarked for indigenous peoples. This status is conditioned upon a maximum group size of 50,000.

Perceived and measured levels of environmental pollution: interdisciplinary research in the subarctic lowlands of northeast European Russia.

Using interdisciplinary field research in the Usa Basin, northeast European Russia, we compared local inhabitants' perception of environmental problems with chemical and remote-sensing signatures of environmental pollution and their local impacts. Extensive coal mining since the 1930s around Inta and Vorkuta has left a legacy of pollution, detected by measuring snowpack, topsoil, and lichen chemistry, together with remote-sensing techniques and analysis of lake water and sediments. Vorkuta and its environs suffered the worst impacts, with significant metal loading and alkalization in lakes and topsoils, elevated metals and cations in terricolous (reindeer) lichens, and changes in vegetation communities.
