“…In anurans, these aggregations are called choruws because the males v o d i z e to attract females. An individual male's attendance at choruses, measured in number of nighrs, is calIed chorus tenure (Murphy 1994a). Maies have a low probability of acquiring a mate on any given night if female arriva2 at choruses is spread out over time and the operational sex ratio (OSR) is highly male biased (Emlen and Onng 1977).…”

“…Males of prolonged or explosive breeding species (sensu WELLS, 1977) may be territorial (ROBERTS, 1994;BASTOS & HADDAD, 2002). However, territoriality is more accentuated in prolonged breeders because females generally arrive asynchronously in choruses with males (WELLS, 1977;MURPHY, 1994).…”

ABSTRACT. From January, 1997 to April, 1998, we studied breeding activity in a population of Scinax centralis Pombal & Bastos, 1996, in the state of Goiás, inside the Cerrado Biome, Brazil. The behavior of males and females in the choruses, the relationships between environmental variables and the presence of individuals, the spatial distribution pattern, amplexus and clutches were analyzed. The breeding season occurred from November to May. The majority of males began to call when they entered the chorus; they were defending their calling sites against other males. We found a positive correlation between the number of females and males in the choruses, but no significant correlation was observed between the operational sexual ratio (OSR, number of reproducing females/number of reproducing males) and the number of calling males. OSR was highly male-biased; on average, there were 40 males for each female. The presence of individuals was positively correlated with air temperature of two previous days and negatively correlated with rainfall on the observation day. Generally, males were non-randomly distributed and satellite males were observed. Females were larger and heavier than males. Egg number, but not diameter of the egg, was correlated with the female size.

“…In this case, males must maintain a territory that is free of competitors and vocalize to attract females that are ready for oviposition (Wells 1977a, Murphy 1994. Thus, in anurans with this type of reproduction, the success of the reproductive male frog depends on the male's ability to attract females to the calling site by emitting varied and complex calls, and to defend his territory from intruding males.…”

Territorial and mating behavior in Phyllomedusa azurea (Anura: Hylidae) at a temporary pond in west-central Brazil. We studied territorial and mating behavior of Phyllomedusa azurea in the municipality of Cocalzinho de Goiás, Goiás, which is located in central Brazil. During the mating season, male P. azurea engage in territorial behavior that is associated with vocalizations-advertisement, territorial, fight, or a combination of two more of these. When one male frog invades the territory of another, they commonly emit of territorial calls and engage in physical combat. Three main behavioral traits were observed in mating males-viz., "male-singer," "active search" and "male-shifter." Males vocalize during the amplexus and oviposition. No aggression between females P. azurea was observed.
