“…Among dendrobatids, multiple clutches at the same site have been reported for E. flavopictus (Toledo et al 2004; present study) and for Colostethus nidicola (Caldwell & Lima, 2003). This association between the male and the egg laying site may be indicative of the existence of parental care in the egg phase in these species, as already recognized in other species of the family (Weygoldt 1987, Pröhl & Hödl 1999).…”

“…Toledo et al (2004) depicted a clutch of eggs of Epipedobates flavopictus in a mass; however, we found that eggs were spread in small groups. Dendrobatids are known to reproduce in primary or secondary forests (Rodriguez & Duellman 1994), even those from the Cerrado (Haddad et al 1988, Haddad & Martins 1994.…”

“…Some interpopulational variation in adult size and color has been recognized (Haddad & Martins 1994). Haddad et al (1988) and Haddad & Martins (1994) described the call and the tadpole, and Toledo et al (2004) described egg clutches and parental care in populations from Minas Gerais. In spite of these previous studies, some aspects of the behavior of E. flavopictus remain unknown, and interpopulational differences in morphology and call parameters are only partly documented.…”

Courtship, vocalization, and tadpole description of Epipedobates flavopictus (Anura: Dendrobatidae) in southern Goiás, Brazil

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. In November, males vocalized daily during two distinct periods, between 04:30 h and 10:00 h and between 16:30 h and 20:00 h. Morning temperature varied between 20-23ºC and humidity from 79-89%; during evening varied between 24-27ºC and 54-82%. In the middle of the day, temperature reached 36ºC and humidity 40%. During the morning, call activity was almost uninterrupted, in the evening calling bouts lasted around 9 min. In February, even with the occurrence of rainfall and temperatures similar to that of November no frog vocalized. The advertisement call is composed by a single note with 7-8 pulses with frequency ascending slightly from 3.20 to 4.05 kHz. Note duration was 144 ms, and between note intervals is 292 ms. Notes are given at a rate of 139 per minute. Upon observing the female, the male began to emit courtship call. The female approached the male and touched him laterally with her snout. The male moved forward and raised his hindquarters by stretching his hind legs. While leading the female, the male continued to give courtship and advertisement calls. The male clasped the female in axillary amplexus, and the pair entered a hole in a bank. The female deposited eggs on the surface of the soil, spreading them in groups. The egg clutches had eggs in at least two developmental stages, recently deposited and with embryos. Tadpoles were found in small, shallow rocky pools along a permanent stream, in well-illuminated sites at the forest border. The tadpole had the dorsal fin arched, not extending onto body. E. flavopictus appears to be unique among dendrobatids by using open areas subject to high temperatures and low humidity. Reproductive activity of the species ends before the end of the rainy season, possibly to avoid loss of tadpoles during months with unpredictable rainfall. The studied call had more notes and shorter between-call intervals than those described from other populations. The free-living tadpoles we describe differ from those of other populations by having the dorsal fin reduced.

“…In a population of A. flavopicta from central Brazil, similar findings were reported by Toledo et al (2004), who argued that the low intensity of courtship call may represent an adaptation to avoid detection of a newly formed reproductive pair by neighbouring males.…”

Ameerega braccata is an aposematic, small dendrobatid anuran known from its type-locality, Chapada dos Guimarães, in the State of Mato Grosso, and from a few additional localities in Mato Grosso do Sul and Goiás States, Brazil. The advertisement call of A. braccata is composed of a single unpulsed note, with a frequency range from 3.5 to 4.2 KHz (N = 110), and average duration of 65.8 ms (N = 110, SD = 11.6). The territorial call is composed of five or six repeated notes, structurally similar to advertisement call notes. The courtship call is emitted in close-range interactions between male-female during the courtship event and may reach frequencies of 2.2 to 5.3 KHz (N = 10), with shorter notes (average duration 43 ms; N = 10; SD = 4.9). Call duration, note duration and call rate of the advertisement call showed high variation (>15% of coefficient of variation), and dominant frequency showed low variation (<4%). The properties with higher variation possibly respond to climatic features and male social position. When producing advertisement calls, males were usually found at an average height of 31.4 cm (N = 19, SD = 12.2 cm), mainly on leaves of shrubs and herbaceous plants (59%). Individuals of A. braccata were found in open physiognomies in the Cerrado ("campo sujo" and "cerrado stricto sensu"), as opposed to that found by previous researchers, who reported an association of the species with gallery forests in the Cerrado.Keywords: Amphibia, Dendrobatidae, Ameerega braccata, vocalization, habitat use.Comunicação acústica e microhabitat de vocalização em Ameerega braccata (Steindachner, 1864) (Anura, Dendrobatidae) do centro-oeste do Brasil ResumoAmeerega braccata é um pequeno anuro aposemático da família Dendrobatidae, conhecido de sua localidade-tipo, Chapada dos Guimarães, Mato Grosso e outras localidades adicionais em Mato Grosso do Sul e Goiás, Brasil. A vocalização de anúncio de A. braccata é composta de uma única nota, não pulsionada, com amplitude de frequência entre 3,5 e 4,2 KHz (N = 110) e duração média de 65,8 ms (N = 110, DP = 11,6). A vocalização territorial é composta por cinco ou seis notas repetidas, estruturalmente similares às notas da vocalização de anúncio. Vocalização de corte é emitida em interações de proximidade entre machos e fêmeas durante o processo de corte, podendo alcançar frequências entre 2,2 e 5,3 KHz (N = 10), com notas curtas (duração média 43 ms; N = 10; DP = 4,9). A duração do canto, a duração da nota e a taxa de repetição de canto de anúncio apresentam alta variação (>15% de coeficiente de variação), ao passo que a frequência dominante apresenta baixa variação (<4%). As propriedades com variação alta podem variar de acordo com características climáticas e possivelmente em função do contexto social do macho emissor. Quando em exibição de anúncio, os machos foram usualmente encontrados a uma altura média de 31,4 cm (N = 19, DP = 12,2 cm), principalmente sobre folhas de arbustos e plantas herbáceas (59%). Indivíduos de A. braccata foram encontrados em fisionomias abe...

“…Among them, some species as Ameerega flavopicta, endemic to the Cerrado biome, were observed only in areas of Cerrado stricto sensu. A. flavopicta occupy open physiognomies of the Cerrado ecosystem, with males calling mainly from rock crevices (Toledo et al 2004;Costa et al 2006;Magrini et al 2010;Martins and Giaretta 2012). The species is considered to be of ''Least Concern'' by the International Union for Conservation of Nature (IUCN, 2013).…”

Even harboring a high diversity and many endemic species of amphibians and reptiles, the Cerrado biome has shown drastic changes due to the conversion of natural areas into pastures and plantations. Here, we present a checklist of amphibians and reptiles from southeastern state of Goiás, Central Brazil. This checklist was the result of collecting efforts of an inventory along the basin of the Piracanjuba and Peixe rivers carried out between September 2010 and January 2011. We recorded 39 amphibians and 40 reptiles. These results were also compared to other studies in the Cerrado biome. Our results showed that this region has a rich herpetofauna, despite the progress of anthropogenic activities in the region.
