Are environmental factors responsible for geographic variation in the sex ratio of the Greenlandic seed‐bug Nysius groenlandicus?
Abstract Until recently nothing indicated an unequal sex ratio in the widespread Greenland seed‐bug Nysius groenlandicus (Zetterstedt) (Heteroptera: Lygaeidae). However, recently populations more or less devoid of males were discovered in high arctic Northeast Greenland. This initiated an inspection...
