摘要：In this study is presented information about species richness, vocalization season and calling site usedin anurans assemblage located in San Cosme, Corrientes, Argentina. A total of 22 samplings were made betweenOctober of 2010 and September of 2011. Four sites were selected and the techniques applied were: visual encountersurveys and auditives bands transects. A total of 27 species of anurans were registered belonging to 5 families:Hylidae (11), Leptodactylidae (13), Microhylidae (1), Odontophrynidae (1) and Bufonidae (1). Three patterns withregard to vocalization season were assigned: prolonged, intermediate and explosive. Most of the species (20) showedintermediate vocalization pattern and 3 species showed prolongated vocalization pattern. The largest aggregationswere observed in December of 2010 and the smallest in June and July of 2011. The number of males in activity ofvocalization was influenced by the daily mean temperature and monthly mean temperature. Also, the reproductiveactivity was registered only in 37% of anurans species. Spatial distribution was more important than temporaldistribution to explain the coexistence of this anuran assemblage.
