Parasite manipulation of sexual signalling.

Organisms express sexual signals to indicate to potential mates of their intention, health condition and capability in ensuring the subsequent survival and reproduction of its young. Such signals are expressed by traits that organisms possess, such as horns and colourful outer coverings (e.g. birds’...
