Foam nest construction and first report of agonistic behaviour in Pleurodema tucumanum (Anura: Leptodactylidae)

Reproductive strategies are the combination of physiological, morphological, and behavioural traits interacting to increase species reproductive success within a set of environmental conditions.  While the reproductive strategies of Leiuperinae are known, few studies have been conducted regarding the reproductive behaviour that underlies them. The aim of this study was to document the structural characteristics of nesting microsites, to describe the process of foam nest construction, and to explore the presence of male agonistic and chorus behaviour in Pleurodema tucumanum. Nests were found close to the edge of a temporary pond and the mean temperature of the foam nests was always close to the mean temperature of the pond water. Our observations corroborate that the foam nest construction phases for P. tucumanum are similar to those described for other Leiuperinae, including dispersion and the beating of the foam, realized by male hind limbs. We also recorded the first scientific observations of male agonistic encounter in Pleurodema tucumanum.
