Hard-shell mating in Neohelice granulata: the role of ecdysone in female receptivity and mate attraction
Most brachyuran females become receptive during the intermolt period, a condition considered “derived”. However, as far as we know, studies testing the existence and function of pheromones in decapods are based on species which have mating linked to molting, a condition considered as “ancestral”. Fo...
