Dr Sheri Johnson

Sheri is a reproductive and behavioural ecologist and is a lecturer based at the Department of Zoology at the University of Otago. Born and raised in Canada, Sheri graduated with a BSc (Hons) at Dalhousie University, before moving on to the University of Maine to complete her PhD in 2007. Sheri was a postdoctoral fellow at the University of Florida and then moved to New Zealand to take up a research fellow position in the Department of Anatomy at Otago in 2010. Sheri has broad interests in ecology, evolution and behaviour. Her research includes sexual selection, mating system evolution, alternative reproductive tactics, sperm biology, male aging, and epigenetics. Sheri uses an integrative approach (molecular, field ecology, reproductive biology and behavioural analysis) to understand the factors that affect reproductive success and mate choice in fish and marine invertebrates. She has a particular interest in horseshoe crabs as a model for understanding sexual selection and the evolution of mating systems.

SEX ON THE BEACH

Horseshoe crabs might seem unremarkable, but their sex lives will amaze you! Horseshoe crabs are considered ‘explosive breeders’. But
Dr Sheri Johnson’s work reveals that this is not just an unorganized orgy; both males and females have adopted strategies to ensure reproductive success, often resulting in conflict between the sexes.
