How do males of Hypsiboas goianus (Hylidae: Anura) respond to conspecific acoustic stimuli? Rev. Bras. Zool.
Morais,Alessandro R.; Siqueira,Mariana N.; Bastos,Rogério P..
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 behavior in response to conspecific advertisement calls. Specifically, we used different field playback experiments in which we modified the time interval between advertisement calls to simulate males with distinct states of motivation (Sequence A and B). We did not observe differences in the acoustic response of males of H. goianus between the two types of field playback experiments. On the other hand,...

Reproductive activity and vocalizations of Leptodactylus labyrinthicus (Anura: Leptodactylidae) in southeastern Brazil Biota Neotropica
Zina,Juliana; Haddad,Célio F. B..
Vocalizations and reproductive activity of two Leptodactylus labyrinthicus populations were studied from Jun/2001 to Feb/2003 in the State of São Paulo, Brazil. Observations began at dusk and ended around 2300 h. Occasionally individuals were monitored throughout the night. Data on reproductive period, calling sites, adult snout-vent length (SVL), oviposition sites, and oviposition period was collected. Leptodactylus labyrinthicus had an extended breeding period associated mainly with rainfall. Males called from the edge of temporary or permanent ponds, began vocalization activity at dusk, and finished around 2300 or 2400h. During the peak of the vocalization period (Dec- Jan), calling activity could extend up to 0400 or 0500h. Three types of vocalizations...

Reproductive aspects of Dendropsophus sanborni (Anura, Hylidae) in northeastern Argentina Iheringia, Sér. Zool.
Curi,Lucila M.; Olea,Gabriela. B.; Álvarez,Blanca B.; Céspedez,Jorge A.; Lombardo,Daniel M..
Reproductive aspects of Dendropsophus sanborni (Anura, Hylidae) in northeastern Argentina. The aim of this investigation was to characterize reproductive aspects of Dendropsophus sanborni (Schmidt, 1944) (Anura, Hylidae) in the northwest of Corrientes province, in northeastern Argentina. The reproductive cycles of males and females, the existence of sexual dimorphism and the male’s vocalization period were analyzed. Samplings were made from September 2011 to August 2012. Dendropsophus sanborni showed a prolonged reproductive pattern because reproductive activity was observed during most part of the year. Calling males were recorded all months except in July. The spermatogenic cycle can be characterized as potentially continuous. In males, snout-vent length...

Systematic notes on Asian birds. 21. Babbler jungle: a re-evaluation of the ‘pyrrogenys’ group of Asian pellorneines (Timaliidae) Naturalis
Wells, D.R.; Andrew, P.; Berg, A.B. van den.
The taxonomy of the jungle babblers, Delacour’s tribe Pellorneini, has long been subject to reversals of opinion, suggestive of a still-poor understanding of natural relationships. At the unstable boundary of genera Trichastoma and Pellorneum, groups of taxa usually taken to comprise a continental species tickelli and an insular species pyrrogenys have shifted from positions in separate genera to being neighbours in first one and then the other of these two. A fresh morphological analysis and newly described vocalizations show them to be one another’s probable closest relative, potentially conspecific but due to limitations on the allowable use of vocalization evidence among allopatric populations, for the time being at least, kept as separate entities....

Systematic notes on Asian birds. 41. Territorial songs and species-level taxonomy of nightjars of the Caprimulgus macrurus complex, with the description of a Naturalis
Sangster, G.; Rozendaal, F.G..
The Large-tailed Nightjar Caprimulgus macrurus Horsfield, 1821, complex, as currently recognized, comprises 12 taxa which are grouped into four species based on their territorial songs. However, species limits are based on very small samples of a limited number of taxa in the complex. To further document species limits in the complex, we analysed 109 sound recordings representing all recognized taxa. Principal components analysis suggests the existence of six vocally distinct groups within the complex. Discriminant function analysis assigned 98-100% of individuals correctly to their group. Each of these groups differs diagnosably from all other groups by up to eight vocal characters, and each group is recognizable by ear. We propose to treat these six...

Systematic notes on Asian birds. 44. A preliminary review of the Corvidae Naturalis
Dickinson, E.C.; Eck, S.; Martens, J..
Certain Asian species of corvids, mainly those that have been reviewed since 1962, are discussed and attention is drawn to recommended changes in subspecific or specific status. Problem areas remain and research is suggested, some morphological, some molecular and some into voice. The rationale behind the ongoing revision of Corvus macrorhynchos is explained, but it is recommended that it be considered hypothetical and further developments awaited so that all relevant taxa can be assigned safely to species.

Vocalizations and comments on the relationships of Hypsiboas ericae (Amphibia, Hylidae) Iheringia, Sér. Zool.
Garcia,Paulo C. A.; Haddad,Célio F. B..
The vocalizations of Hypsiboas ericae (Caramaschi & Cruz, 2000) are described and new information on the external morphology and osteology of the species are presented. H. ericae presents a bony spine in the prepolex and the individuals can present green or brown dorsal color, as other species of the Hypsiboas pulchellus (Duméril & Bibron, 1841) species group. The vocalizations of H. ericae are similar to the vocalizations of Hypsiboas bischoffi (Boulenger, 1887), Hypsiboas guentheri (Boulenger, 1886), and other species in the H. polytaenius (Cope, 1870 "1869") clade of the H. pulchellus species group, but some osteological aspects are different to those found in the majority of the species of this group.
