“…Similarly, in an anuran community of southern Brazil, L. mistacynus vocalized for three months, a reproductive pattern intermediate between species active for more than five months and species with only a few nights of activity (Toledo, Zina and Haddad, 2003). Also similar to our observations, in cen-tral Brazil L. mystacinus was active in months of high rainfall, humidity and temperature (de Oliveira Filho and Giaretta, 2008;De-Carvalho et al, 2008).…”

Spatial and temporal patterns of richness and abundance in the anuran assemblage of an artificial water reservoir from the semiarid central region of Argentina

This constitutes the first study of anuran fauna composition of an artificial permanent water reservoir, in a semiarid ecosystem of San Luis. Species richness, relative abundance, spatial distribution and pattern of summer activity were estimated in the anuran community of the Embalse La Florida, an artificial water reservoir in the semiarid central region of the sierras of San Luis, Argentina. This reservoir represents one of the few sources of water available for reproduction and early development of amphibian species in the zone. We identified anurans using call surveys during two summers at fifteen sites, belonging to four zones around the shorelines of the reservoir. Eight amphibian species (Rhinella arenarum, Melanophryniscus stelzneri, Leptodactylus bufonius, Leptodactylus mystacinus, Odontophrynus americanus, Odontophrynus occidentalis, Pleurodema tucumanum and Hypsiboas cordobae) were recorded at the shores of the embalse. The highest species richness (seven) was detected in the preserve located on the north shore. Species richness analyzed by month or survey was not correlated with weather variables. The highest relative abundance of anurans was detected at the highly modified campsites area, which may provide stable food and refugia. Relative abundance of all anuran species was positively correlated with precipitation. This permanent water reservoir may act as an important site of amphibian fauna concentration, which is important to monitor and preserve.

“…The advertisement calls of Leptodactylus mystacinus analyzed in this study showed a structure similar to previous descriptions (Barrio, 1965;Oliveira Filho & Giaretta, 2008). We only found differences with the call duration reported by Barrio (1965), of 100 ms; however, suggested that the record of these high values could be due to the methodology employed.…”

“…5B). This behavior was never reported neither for its close relative L. mystacinus (Barrio, 1965;Langone, 1995;Abrunhosa et al, 2001;Oliveira Filho & Giaretta, 2008) nor for any other Leptodactylus species or genus in Leptodactylidae (Lynch 1971;Heyer 1978;de Sá et al, 2014). Reproductive males of L. mystacinus vocalize at shelter under dead logs or rocks, and males of most species in the L. fuscus group usually call from the ground, near or inside underground chambers that they construct for reproduction (Heyer, 1978;de Sá et al, 2014).…”

Peer Review #1 of "A new frog of the Leptodactylus fuscus species group (Anura: Leptodactylidae), endemic from the South American Gran Chaco (v0.1)"

A new species of Leptodactylus frog (Anura: Leptodactylidae) from the South American Gran Chaco, morphologically similar and previously confused with the widespread L. mystacinus, is described, through the use of multiple sources of evidence (molecular, external morphology, coloration, osteology, bioacoustics, and behavior). The phylogenetic analysis with partial sequences of mitochondrial rDNA genes (12S and 16S) recovered the new species within the L. fuscus group, but being highly divergent (> 3 % genetic distance in 16S). The new species was recovered as sister taxa of L. mystacinus, from which it is distinguished by tympanum coloration, cephalic index, dorsum and legs coloration, and some osteological differences in nasals and prevomers. This new frog is characterized by a moderate body size (SVL 46.80-66.21 mm), distinctive color pattern (reddish dorsal surfaces of body with noticeable black stripes in the dorsolateral folds), a circular and dark tympanum with dark tympanic annuli, and behavior of males that call on top of fallen logs and tree branches close to the ground.

“…Nevertheless, the observations of the incubation chamber construction are quite rare and lacking for most of the species of the group. Reports about which sex excavates the burrow exist for Leptodactylus bufonius (Cei 1949; Reading and Jofré 2003), Leptodactylus mystacinus (Oliveira Filho and Giaretta 2008), L. fuscus (Cei 1949; Martins 1988; Giaretta and Kokubum 2004), Leptodactylus mystaceus (Caldwell and Lopez 1989), and L. latinasus (Gallardo 1958, 1964) . If we had found sexual dimorphism in the nasal capsules or head dimensions of L. latinasus , then the relationship of these characters with the construction of the incubation chamber might have been used to predict that sex is involved in this behavior for species in the group for which there are not behavioral observations.…”

Ponssa, M.L. and Barrionuevo, J.S. 2012. Sexual dimorphism in Leptodactylus latinasus (Anura, Leptodactylidae): nasal capsule anatomy, morphometric characters and performance associated with burrowing behavior. -Acta Zoologica (Stockholm) 93: 57-67.In anurans, the ability to burrow has been associated with the characteristics of external morphology, with modifications in the musculoskeletal system and even in some brain regions. Male Leptodactylus fuscus construct subterranean chambers with the snout, where the eggs are deposited and early larval stages develop. Leptodactylus latinasus, a member of the L. fuscus group, is a good model to test the relationship among digging behavior of males, sexual divergence in the morphology of the nasal region, cranial-dimensions, and performance as digger. The goal of this work is to provide a detailed morphological description of the olfactory region, which allows detecting sexually dimorphic characters, to evaluate sexual divergence with head dimension data, and to test whether differences exist in the digging performance of each sex. Our data do not clearly indicate sexual dimorphism in head size, nasal region morphology or digging performance that can be linked with the burrowing behavior. Thus, the only unequivocal sexually dimorphic character associated with the construction of the nuptial chamber by males would be the rigid, chisel-like snout, present exclusively in males.
