Indications of contagious behaviours in the southern
elephant seal: an observational study,
Behaviour, in press.

Wojczulanis-Jakubas K, Plenzler J, Jakubas D


Behavioural contagion has been demonstrated in humans and animals but how widespread the phenomenon is remains unclear, as only a few species have been tested. In this context, we examined whether “sneezing”, scratching and yawning exhibited by moulting southern elephant seals could be contagious. Using the randomization approach, we found this to be the case in general for all the behaviours, although the pattern was not that obvious in all the tested social groups. This indicates there is a potential for social contagion but the issue is complex. This is the first report of contagious behaviours in marine mammals and is to encourage further investigation. More results, 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!
