Reproductive success in the Lusitanian toadfish : Influence of calling activity...
Amorim, Maria Clara Pessoa; Conti, Carlotta; Santos, Carla Sousa; Novais, Bruno; Gouveia, Maria D.; Vicente, Joana R.; Modesto, TeresaAcoustic signals are sexual ornaments with an established role on mate choice in several taxa, but not in fish. Recent studies have suggested that fish vocal activity may signal male quality and influence male's reproductive success but experimental evidence is lacking. Here we made two experiments to test the hypothesis that vocal activity is essential for male breeding success in a highly vocal fish, the Lusi...

Agonistic sounds signal male quality in the Lusitanian toadfish
Amorim, Maria Clara Pessoa; Conti, Carlotta; Modesto, Teresa; Gonçalves, Amparo; Fonseca, Paulo JorgeAcoustic communication during agonistic behaviour is widespread in fishes. Yet, compared to other taxa, little is known on the information content of fish agonistic calls and their effect on territorial defence. Lusitanian toadfish males (Halobatrachus didactylus) are highly territorial during the breeding season and use sounds (boatwhistles, BW) to defend nests from intruders. BW present most energy in either ...
How effective are acoustic signals in territorial defence in the Lusitanian toa...
Conti, Carlotta; Fonseca, Paulo Jorge; Picciulin, Marta; Amorim, Maria Clara PessoaThe function of fish sounds in territorial defence, in particular its influence on the intruder's behaviour during territorial invasions, is poorly known. Breeding Lusitanian toadfish males (Halobatrachus didactylus) use sounds (boatwhistles) to defend nests from intruders. Results from a previous study suggest that boatwhistles function as a 'keep-out signal' during territorial defence. To test this hypothesis...
