(Table 1) Dominant species and total biomass of macrozoobenthos communities in the southwestern Kara Sea

The structure and distribution of the macrobenthic communities were studied in the southwestern Kara Sea. The material was collected in Baidaratskaya Bay in July 2007 and in a section running westward of the Yamal Peninsula in September 2007. The depths of the sampling stations ranged from 5 to 25 m in the Baidaratskaya Bay area and between 16 and 46 m in the Yamal section. A total of 212 benthic invertebrate species were recorded. In both areas, Bivalvia was the group with the highest biomass (54.88 g/m**2 in the Yamal section and 59.71 g/m**2 in the Baidaratskaya Bay area), while polychaetes were the group with the highest number of species (45 in the Yamal section and 64 the Baidaratskaya Bay area). Three major macrozoobenthic communities were recognized: the Astarte borealis community (20-46 m, the deepest sampling stations in both areas); the 'medium-depth' community (10-20 m, extremely mosaic, usually dominated by Serripes groenlandicus); and the Nephtys longosetosa community (depth smaller than 10 m, characterized by low biomass and the absence of large bivalves and echinoderms). The western Yamal shallow-water communities were shown to be generally similar to those of Baidaratskaya Bay. The comparison of these results with those of the benthos censuses performed in 1927-1945, 1975, and 1993 showed that the benthic communities in the southwestern Kara Sea remained relatively stable during the second half of the 20th century and the early 21st century.

Social differentiation of risk: perceptions of the future in drought-prone Central Niger

A snapshot of two Tuareg-dominated 'communes rurales' in the pastoral-agricultural transition zones of Maradi and Tahoua regions, Central Niger, shows that, despite the openly shared 'inevitable natural hazard' drought discourse, risk-taking action in response to drought-related dangers is sharply polarized according to social position. On the one hand the dominant Tuareg minority perceive drought not only as danger for their herds but also as opportunity to increase their political following through the channelling of drought relief benefits to their supporters. On the other hand, the majority of commune households, living on the brink of economic viability, cultivate social links with the dominant families in order to secure access to water, land and humanitarian aid; and household members are forced into more and more frequent and distant out-migration. Certain leaders, well-informed about national land policy and practice, focus their efforts for a better future on the consolidation of community land rights through the promotion of certain sedentarization and land privatization initiatives; however the resulting increased land pressure in key locations may unwittingly expose inhabitants to even worse drought-linked crises in the future.
