A review of social recognition in pinnipeds

摘要: A substantial amount of research has been carried out on recognition behaviour in natural popu- lations pinnipeds. This work includes detailed anecdotal and quantitative descriptions addition to situ experimental tests recognition. The goals this review are summarize research, by doing so, point apparent patterns social among the pinnipeds, as well important gaps our knowledge. Following an introduction topic, is divided into three sections: (1) descriptive evidence, (2) exper- imental (3) pinnipeds resulting from phylogenetic, ecological life history constraints. evi- dence mostly pertains between motherand oVspring vocal stereotypy, use other sensory modalities, cases adoption allo-suckling.
