Paolo Ghislandi

During his studies, Paolo Ghislandi explored how males employ different tactics to increase their mating success. Alternative reproductive tactics represent a hot topic in behavioural and evolutionary biology, as the causes underlying the choice of a particular tactic from a set of possible options are still poorly understood. Why do males behave the way they do?

Focusing on the nursery-web spider, Paolo Ghislandi investigated which tactics a male can employ to be accepted by females, what promotes their use, and which factors explain differences in tactic use among different spider populations.

 

The new research findings contribute to the understanding of how phenotypic variation is maintained in the context of reproduction and which are the evolutionary causes promoting the use of different tactics.
