From July, 12 till August, 31, 2015 a research expedition to the Western part of the Laptev Sea took place. During the expedition we collected unique scientific materials, found a new seagull species for the first time in Russia, made notes on changes in geographic range of some birds and plants species, and we probably found a new shellfish species.

During the research Lena-Taimyr expedition in 2014 we made photos of the rarest Chekanovsky poppy described on the basis of botanic collections.
