Advertisement and courtship calls of Dendropsophus nanus (Boulenger, 1889) (Anura: Hylidae) from its type locality (Resistencia, Argentina) Biota Neotropica
Teixeira,Bernardo Franco da Veiga; Zaracho,Víctor Hugo; Giaretta,Ariovaldo Antonio.
Abstract Dendropsophus nanus was described from Resistencia, Argentina. The species distribution is widespread in South America east of the Andes. Despite its wide distribution, little information about its advertisement call is available in the literature. Call descriptions from type localities are especially important for the resolution of taxonomic issues, as well as for intraspecific comparisons. Herein we describe the advertisement and the male courtship calls of D. nanus from its type locality. The advertisement call of D. nanus is composed of two types of pulsed notes, herein referred to as “note A” (long note) and “note B” (short note), both with similar dominant frequencies, but different durations. The courtship call is formed by notes that are...

Courtship, vocalization, and tadpole description of Epipedobates flavopictus (Anura: Dendrobatidae) in southern Goiás, Brazil Biota Neotropica
Costa,Ronan Caldeira; Facure,Kátia Gomes; Giaretta,Ariovaldo Antonio.
Epipedobates flavopictus is a diurnal, aposematic dendrobatid with a wide distribution in seasonal wet tropical regions of Brazil. We describe the daily period of vocalization, advertisement call, courtship behavior, and tadpole of E. flavopictus from a previously unknown population in southern Goiás and compare theses features with that of other populations. Studies were carried out in November (2004) and February (2005). We counted the number of calling males and duration of calling bouts in the morning and evening periods. The advertisement call was recorded with a digital recorder. Tadpole description was based on specimens collected in pools. Males called from well-illuminated sites such as rocky fields, rain channels, and borders of riverine forests....

Diversity and abundance of litter frogs at altitudinal sites at Serra do Japi, southeastern Brazil Zoologia
Giaretta,Ariovaldo Antonio; Sawaya,Ricardo J.; Machado,Glauco; Araújo,Márcio S.; Facure,Kátia G.; Medeiros,Hermes F. de; Nunes,Renato.
It was sampled the litter frogs at altitudinal sites of a semideciduous mesophytic forest located at Sena do Japi (Jundiaí, São Paulo, 23º17'S, 47º00'W, 800-1300m altitude, 1500mm rain/year). Forty two plots of 8x8m were sampled in the dry/cold season of 1995: 21 at a Higher Site (HS) (1000m) and 21 at a Lower Site (LS) (850m). The plots were evenly located near, mid-distance, and far from the stream-bed. It was found a total of five species, three at each site. Eleutherodactylus guentheri comprised 83% of the individuals at HS and E. juipoca 67% at LS. The density of individuals was higher at HS and near the stream. The greater density at HS may be due to greater humidity there, provided by mist. The frogs may aggregate in wetter places (stream edges) in...

Reproductive ecology and behavior of Thoropa miliaris (Spix, 1824) (Anura, Leptodactylidae, Telmatobiinae) Biota Neotropica
Giaretta,Ariovaldo Antonio; Facure,Kátia Gomes.
Thoropa species are distributed in southern and southeastern Brazil and have semiterrestrial tadpoles on rocky environments. Herein, we provide further data on reproduction, paternal care and tadpole cannibalism in T. miliaris. Guarding males were tested for disturbances in their egg masses. Egg masses were laid in stripes of wet rock; eggs were in a single layer and were adhered to the rock surface, roots, and to one another. The tadpoles hatched between four and six days. The egg number in two egg masses was 750 and 1190; eggs were gray and the yolk were about 1.7 mm in diameter; 2.3 mm with the jelly capsule. Aggressive interactions were observed between males. Males remained with their egg masses during the night and reacted aggressively to the...
