title: Territorial Polemics: A Response to Roberts.
abstract: Our recent paper Lledo-Ferrer et al. (International Journal of Primatology 32: 974-991, 2011) questioned the classic view of territoriality and chemical communication in wild callitrichids, saddleback tamarins (Saguinus fuscicollis). We suggested that rather than defending a territory or resources, chemical communication was more likely to be a way of exchanging reproductive information between groups. Roberts (International Journal of Primatology 33, 2012). challenged this interpretation, considering that the results could more parsimoniously be interpreted as fulfilling a resource defense strategy. This response is intended to clarify some aspects of the debate and to suggest how further research could shed new light on the present polemics.
