Assortative mating patterns of multiple phenotypic traits in a long-lived seabird


This is a short and purely correlational study but the findings suggest that some phenotypic traits of the little auk (Alle alle) may be a subject of selection via mate choice. Using randomization tests, we showed that regarding wing length, hormonal stress response and extent of white plumage on the eye-lid, pair members are more similar to each other that one could expect by chance. This is the first step to determine how selection operates on mate choice in the little auk. Now, we need to test how the similarity of the breeding partners affects the pair breeding success. In other words, more soon! 

And meanwhile, you can find more details on the current study here.

New species of Tardigrada on Spitsbergen


New species of tiny water bear (Tardigrada) was found and described by Polish reasercher, Krzysztof Zawierucha. The 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!
