Also, the feather of these bird species contains a lot of microelements and in particular heavy metals. For example, the content of lead is more than 1,5 mg g-1 and cadmium – more than 0,2 μg g-1. Therefore, the feather of seabirds is a suitable object for environmental monitoring. We also found out that daily with guano of Pygoscelis adeliae (for an adult) from the ocean to the terrestrial ecosystems comes up to 14 g of carbon, 4-5 g of nitrogen, 0,5-1 g of phosphorus, 1 g of calcium, 0,5 g of sulfur. Guano of Pygoscelis papua contains less nitrogen (6,5-7%) comparing to з Pygoscelis adeliae (10-11 %). However, in dry mass, Pygoscelis papua produce1,3-1,5 more guano than Pygoscelis adeliae, more nutrients originate from guano of Pygoscelis papua. It was identified that content of water-soluble carbohydrates in the initial Antarctic soils was high – up to 33-50% of cold-water extractable organic carbon. Therefore, these soils may be strongly affected by global climate changes – higher temperatures may increase decomposition rates of this labile fraction of soil organic matter.
