One of the most serious environmental problems in Russia is the contamination of soil and water through crude oil and crude oil products. The main cause is corrosion damage to oilfield pipes that have outlasted their permitted period of operation. Significant sums of money are needed in order to repair and replace them - sums that the oil companies are

The expansion of shrubs across the Arctic tundra may fundamentally modify land–atmosphere interactions. However, it remains unclear how shrub expansion pattern is linked with key environmental drivers, such as climate change and fire disturbance. Here we

3. Results and discussion The morphology of worms isolated from the peritoneal cavity was identical to S. tundra by light microscopy (Fig. 2). This was confirmed by sequences of the 12S rRNA and cox1 genes, which were 99.1 ‾ 99.8% identical to previously published S. tundra isolates from Germany, France, Italy, Spain and Finland.
