Increased temperature has no consequence for behavioral manipulation despite effects on both partners in the interaction between a crustacean host and a manipulative parasite

Abstract Parasites alter many traits of their hosts. In particular, parasites known as “manipulative” may increase their probability of transmission by inducing phenotypic alterations in their intermediate hosts. Although parasitic-induced alterations can modify species’ ecological roles, the proxim...
