Amphibians from Atlantic Forests of South America are one of the most threatened vertebrates of the world, mainly due to the habitat loss and infectious diseases. With the goal to improve the knowledge of the life-history traits of the amphibian that inhabit these regions, and thus, to aid conservation and management-decision making, our main goals...
Abstract Homonota taragui is an endemic gecko of the northeast of Argentina. We estimate demographic parameters: number of individuals by populations, sex and ontogenetic stage; sexual dimorphism; survival of this species; and describe the use of microhabitat and movement patterns. We measured 11 morphological variables, determined the sex and mark...
Courtship acoustic displays in anuran amphibians are energetically costly and risky, but have a major role in mating success since they encode relevant information regarding the caller’s identity and status. Age and size are essential traits shaping fitness, reproductive success and life-history strategies, and thus are expected to also have a role...
Isolated rocky outcrops represent biodiversity centers, refuges for endangered species, and favorable scenarios for endemism. Most studies in these ecosystems have been focused mainly on their flora and secondarily on different groups of animals. To highlight the value of rocky outcrops as ecosystems for biodiversity conservation, in the present st...
Determining both the age structure and growth pattern allows to establish the causal factors, environmental and/or genetic, that eventually may be responsible for the observed pattern of divergence. We examined the variation in age structure and growth pattern across populations of two toad species, Pelobates cultripes and Epidalea calamita that ex...
Species loss by habitat replacement operating as an ecological filter is a well‐known consequence of modern human activities. In contrast, the ecological and evolutionary response on species overcoming those filters in converted habitats has not been thoroughly explored. Species that persist are subject to novel and potentially stressful conditions...
We studied the chronology of LAG formation and validated the method for estimating age in Argenteohyla siemersi inhabiting the humid Chaco of Argentina. In addition, we tested whether well-expressed growth marks were formed in A. siemersi when raised during one year in laboratory, to determine whether formation was genetically or environmentally ba...
We used skeletochronology to compare age, size, reproductive parameters and growth patterns
of two related, anuran amphibians from Northern Argentina: Leptodactylus bufonius (n=69) and L.
latinasus (n=56), in order to better understand their coexistence in syntopy. Previous studies showed that
the two species overlap in their dietary requirements a...
We studied size, age, and growth in Chacophrys pierottii, a fossorial amphibian inhabiting the arid region of Gran Chaco, in northern
Argentina. We provide the first detailed demographic data for this cryptic species using skeletochronology. We observed female-biased
sexual size dimorphism but no differences in age parameters between the two sexes....
The replacement of native forests by high-density tree plantations affects the richness and composition of animal communities through the modification of the resource availability, hydrological regimes, nutrient cycles and soil structure. Previous studies have been conducted mainly on birds and mammals, whereas few have explored the response of anu...
El Bosque Atlántico Interior es reconocido como un área de alto endemismo y diversidad a nivel global. Para los anuros habitando esta ecorregión su topografía altamente compleja, con varios pequeños microhábitats y la alta humedad del Bosque, reduciendo los riesgos de desecación, favorecerían especializaciones y la persistencia de especies raras, d...
Anurans employ a wide variety of anti-predator mechanisms to defend themselves. In casque-headed hylids, defence is thought to be a complex combination of several anti-predator mechanisms. However, the defence traits of only a few species are known; some hypotheses have yet to be addressed, whereas others, already tested in some species, need to be...
We explored age-related parameters and growth patterns in a population of Dermatonotus muelleri inhabiting the Arid Chaco, at the southern limit of the species' distribution range using skeletochronology. In addition, we studied sexual size dimorphism and female reproductive investment. Males and females attained sexual maturity at a similar age (2...
El 15 Octubre de 2012, a las 19:56 hs. en la Estancia Santo Domingo, Dpto. Paso de los Libres, provincia de Corrientes (29°36?2.10?S, 56°59?23.10?O) se observó un ejemplar hembra de L. annulipes (7,05 cm longitud total) depredando sobre un ejemplar macho de la especie Erythrolamprus poecilogyrus (Wied-Neuwied, 1825) (40,5 cm longitud total). El eve...
Current knowledge on sexual dimorphism and population structure in the genus Odontophrynus is limited. We studied age structure, age at maturity, and longevity in Odontophrynus cf. barrioi, with skeletochronology. We also determined whether sexual dimorphism in body size exists in this species, and evaluated its relation to demographic life history...
On 7 December 2013, we performed an intensive night survey between the localities Fuerte Esperanza and Misión Nueva Pompeya, in the Chaco Province, northern Argentina. The night was preceded by a heavy storm, creating a multitude of temporary ponds. The environmental conditions triggered the explosive reproduction in D. muelleri: vocalizing adult m...
Los relevamientos de fauna silvestre son indispensables para conocer la riqueza de especies en lugares donde la diversidad biológica local aún se desconoce, o ha sido escasamente investigada. Con la finalidad de contribuir a la valorización de la naturaleza de la Reserva Paleontológica del Arroyo Toropí, y generar información útil para su aplicació...
El género neotropical Aleuas Stål 1878 está constituido por nueve especies distribuidas a lo largo de América del Sur. Este género se encuentra cercanamente relacionado con Adimantus Stål 1878, Zygoclistron Rehn 1905 y Episcopotettix Rehn 1903 (Copiocerinae). Únicamente cuatro especies de Aleuas fueron descriptas de distintas provincias fitogeográf...
In this study we analysed the body size, age structure, age at maturity, longevity and growth pattern of Argenteohyla siemersi pederseni in north-eastern Argentina using skeletochronological methods. Body size was sexually dimorphic; females were significantly larger and heavier than males, regardless of age. As A. s. pederseni is an explosive bree...

We studied body size, age structure, age at maturity, longevity, and growth pattern of Physalaemus
fernandezae from a population living at the Reserva Natural Punta Lara, Buenos Aires, Argentina by
skeletochronological methods. Furthermore, we evaluated the sexual size dimorphism of this species in
relation to age at maturity and growth rate. We al...

Eupemphix fuscomaculatus Steindachner, 1864 was described on the basis of a single specimen collected at Caiçara, Mato Grosso, Brazil. This species, currently included in the genus Pleurodema, experienced a confusing taxonomic history and is supposedly known only from the holotype and seven specimens from Río Apa, Paraguay, collected by Alfredo Bor...
Predicting the biodiversity impacts of global warming implies that we know where and with what magnitude these impacts will be encountered. Amphibians are currently the most threatened vertebrates, mainly due to habitat loss and to emerging infectious diseases. Global warming may further exacerbate their decline in the near future, although the imp...
In organisms with complex life cycles, environmentally induced plasticity across sequential stages can have important consequences on morphology and life history traits such as developmental and growth rates. However, previous research in amphibians and other ectothermic vertebrates suggests that some morphological traits are generally insensitive...
The present study describes the reproductive biology of Argenteohyla siemersi pederseni in a modified “quebracho” forest of Schinopsis balansae in northeastern Argentina. Observations were made between January 2007 and March 2009 at El Perichón, Corrientes Province, Argentina. Argenteohyla s. pederseni bred once per year over a 3-day period in a se...
In the toad Bufo calamita, among-population variation of size follows roughly a converse Bergmann cline, but populations exist that do not fit this pattern. We propose that latitudinal body size variation is a byproduct of adaptive covariation among the life-history traits juvenile growth rate, longevity and lifetime fecundity. We choose five popul...
Natale, G.S., Alcalde, L., Herrera, R., Cajade, R., Schaefer, E.F., Marangoni, F. and Trudeau, V.L. 2011. Underwater acoustic communication in the macrophagic carnivorous larvae of Ceratophrys ornata (Anura: Ceratophryidae). —Acta Zoologica (Stockholm) 92: 46–53.
We provide the first evidence for sound production by anuran larvae. In this study, we...
In amphibians from tropical or subtropical regions well-expressed growth marks in bone could be expected because of the existence of strong dry/wet seasons, but little evidence is available. Additionally, temporal patterns of growth-mark formation may be a function of genetic and environmental factors. We used skeletochronology and a laboratory exp...
Geographic variation in body size and reproductive traits has been reported in a wide range of organisms, including amphibians. Most studies have focused on latitudinal and/or altitudinal variation where differences in temperature and duration of the growing season are the main causes for population divergence. We describe a steep variation in body...
The anuran biodiversity and richness of a frog community inhabiting rice fields in northeastern Argentina was surveyed and analyzed. The samples were taken between October 2001 and June 2003. Twenty six species of amphibians were identified in five micmhabitats: rice fields per se, ditches and paths, natural vegetation, aquatic vegetation and gulli...
Determinants of geographic variation in body size are often poorly understood, especially in organisms with complex life cycles. We examined patterns of adult body size and metamorphic traits variation in Iberian spadefoot toad (Pelobates cultripes) populations, which exhibit an extreme reduction in adult body size, 71.6% reduction in body mass, wi...
