black circles = dunes with burrows, white circles = withoutOur 2016 scholarship recipient Johannes Fischer has published another paper in relation to his diving petrel research. This time he compared the occurrence of skinks in dunes with and without diving petrel burrows.
Two skinks were surveyed: the Stewart Island green skink (Oligosoma aff. chloronoton) and the southern grass skink (O. aff. polychroma). Both skinks are more common in the dunes with burrows. However the difference was more pronounced with the Stewart Island green skink. If one of them was present, the other one was less likely to be there too. The larger size of the Stewart Island green skink could explain the different results. It likely outcompetes the southern grass skink.
