1. Comportamento territorial, vocalização e biologia reprodutiva de Allobates olfersioides (Anura: Aromobatidae)
RESUMO Em anfíbios a territorialidade, o cortejo elaborado e outras formas de comportamento, parecem estar mais associados a espécies que exibem o padrão de reprodução prolongado. A vocalização é um importante aspecto biológico relacionado à reprodução e ao comportamento social dos anuros. Este é o primeiro estudo com comportamento e vocalizaç�

2. The advertisement call of the phytotelm-breeding Melanophryniscus xanthostomus (Anura: Bufonidae)
ABSTRACT Vocalizations are often useful for understanding taxonomic relationships among anuran species. Despite this usefulness, vocalizations are described in only nine of 29 in Melanophryniscus Gallardo, 1961. Here we describe the advertisement call of Melanophryniscus xanthostomus Baldo, Bornschein, Pie, Ribeiro, Firkowski & Morato, 2015 of a population f

3. Heritability of advertisement call properties of the Japanese quail
Resumo O objetivo deste estudo foi investigar as variâncias e covariâncias genéticas entre as características do canto de anúncio de codornas japonesas. A duração da primeira, segunda e terceira sílaba, o comprimento do intervalo 1 (entre a primeira e a segunda sílaba), o intervalo 2 (entre a segunda e a terceira sílaba) e o amortecimento (extensã

4. Effect of traffic noise on Scinax nasicus advertisement call (Amphibia, Anura)
ABSTRACT Increased anthropogenic-made sounds such as traffic noises contribute to acoustic pollution, which produces deleterious effect on song-vertebrates. We compared the advertisement call of Scinax nasicus (Cope, 1862) males in natural (as a reference or control, Site A) and Sites affected by traffic noises (Site B). Call structure was recorded and it wa

5. On the distinctive call of a threatened phenotype of Allobates femoralis (Anura: Aromobatidae) and its recognition by allopatric conspecific males
ABSTRACT The brilliant-thighed frog [Allobates femoralis (Boulenger, 1884)]; is distributed across the Amazon basin and aggregates several allopatric evolutionary lineages, some of which present variation in their advertisement calls. In 2009, an unregistered call phenotype was discovered in the region of Altamira and Vitória do Xingu, State of Pará, Brazi

6. How do males of Hypsiboas goianus (Hylidae: Anura) respond to conspecific acoustic stimuli?
ABSTRACT Acoustic communication plays an important role in the social behavior of anurans. Acoustic signals, which can be used in different contexts such as mate attraction and territory defense, may mediate social interactions among individuals. Herein, we used playback experiments to test whether males of Hypsiboas goianus (Lutz, 1968) change their vocal b

7. Advertisement and release calls of Phyllomedusa ayeaye (Anura: Hylidae) with comments on the social context of emission
ABSTRACT Male calls play different roles in anuran social organization, such as spacing, territoriality and female attraction. However, calls and associated behaviors remain poorly described for many anuran species. Here we describe the advertisement and release calls of the tree frog Phyllomedusa ayeaye (Lutz, 1966) and report on the social context of emiss

8. Advertisement call of Dendropsophus microps (Anura: Hylidae) from two populations from southeastern Brazil
In anurans, acoustic communication is a major mechanism of pre-zygotic isolation, since it carries information about species recognition. Detailed descriptions of the acoustic properties of anuran advertisement calls provide important data to taxonomist and to the understanding of the evolution of the group. Herein we re-describe the advertisement call of th

9. Breeding biology and advertisement call of the horned leaf-frog, Proceratophrys appendiculata (Amphibia: Anura: Odontophrynidae)
We describe the breeding biology and the advertisement call of the horned leaf-frog, Proceratophrys appendiculata (Günther, 1873) in the Parque Nacional da Serra dos Órgãos, municipality of Teresópolis. The reproductive period of P. appendiculata is short and is associated with the end of the winter and the beginning of the spring, when males call night

10. Vocal repertory of Scinax littoreus (Anura: Hylidae) with comments on the advertisement call of the Scinax perpusillus species group
The Scinax perpusillus species group consists of thirteen bromeligenous treefrogs, of which only six have had their acoustic parameters appropriately described. In this work, we present the vocal repertory of Scinax littoreus (Peixoto, 1988) based on recordings obtained from three different populations in the state of Rio de Janeiro, Brazil. Based on our obs

11. Advertisement call propagation and species recognition in anurans: in time and space / Propagação e reconhecimento específico do canto de anúncio de anuros: no tempo e no espaço
This study evaluates the influence of the vegetation structure on the advertisement call propagation and the evolution of acoustic communication in anurans. The first chapter reviews the literature on the effects of vegetation in the advertisement-call transmission, addressing directly or not, the Acoustic Adaptation Hypothesis. The studies found were analyz

12. The advertisement call, color patterns and distribution of Ischnocnema izecksohni (Caramaschi and Kisteumacher, 1989) (Anura, Brachycephalidae)
Ischnocnema izecksohni habita as matas de galeria do Quadrilátero Ferrífero, sul da Cadeia do Espinhaço, estado de Minas Gerais, sudeste do Brasil e é considerada endêmica desta região. Sua espécie mais próxima, de acordo com a descrição original, é I. nasuta. Descreve-se o canto de I. izecksohni baseado em espécimes gravados e coletados em Nova
