| dc.description.abstract | Social environmental complexity induces structural and biochemical changes in animals’ brains, which are linked to the improvement of animals’ learning abilities. The nonapeptides from the arginine vasopressin (AVP) family (arginine vasotocin, AVT, in non-mammals) play a significant role in the regulation of social behavior, particularly in the formation of social memories and individual recognition. Moreover, the role of AVT in the regulation of interspecific interactions has only recently started to be addressed in the context of cleaner fish mutualisms and learning. Variance in the distribution of AVP receptor expression, which is linked to distinct neural systems (related to the dorsolateral and the dorsomedial telencephalon), is known to be implicated in differences in individual learning processes. Here we asked if the associative learning performance of the Indo-Pacific bluestreak cleaner wrasse (Labroides dimidiatus) is regulated by AVT. We tested the influence of AVT upon the cleaners’ ability to solve two different problems (cue and place discrimination tasks) that in principle differ in ecological relevance and are associated with two different memory systems. We found that AVT affected the learning competence of cleaners differently between tasks, as individual performance showed distinct response selectivity to AVT dosage levels. However, only in the ecologically relevant task was their learning response improved by blocking AVT via treatment with the antagonist Manning compound. Our findings demonstrate that AVT pathways, which are implicated in the regulation of interspecific behavior (i.e., a cleaner’s willingness to seek interactions with clients), are also linked to individual learning ability in the context of mutualistic behavior, and in tune with socio-ecological demands. | por |
