Exposure of a small Arctic seabird, the little auk (Alle alle) breeding in Svalbard, to selected elements throughout the course of a year 

Although remote and Arctic area is mostly non-industrialised and sparsely occupied, it is still exposed to multiple pollutants. To assess the range and effect of anthropogenic contamination in this unique and fragile ecosystems it is important to monitor their concentration in the Arctic organisms. In this study we examined concentrations of nineteen elements in various samples (feathers moulted in different parts of the year, and egg-shells) collected from a High Arctic seabird, the little auk. Our results indicate high exposition of birds to various contaminants but primarily outside the High Arctic (during their wintering period). While in the Arctic zone, the birds seem to be relatively free of human-originated contaminants. That is a good news but the pollution is a dynamic issue and it is important to keep this monitoring. Therefore, our results apart from being a base of assessment of the current situation constitute a valuable source of reference for future studies. More here.

New species of Tardigrada on Spitsbergen

New species of tiny water bear (Tardigrada) was found and described by Polish reasercher, dr Krzysztof Zawierucha. The little guy was named after me, as I was the one who picked up the precious sample from the ground :)

"Etymology.— Karen means Katarzyna in Norwegian. I dedicate this new species to Katarzyna Wojczulanis−Jakubas from the University of Gdańsk (Poland) who collected the material."

Thank you Krzysztof!
