Changes in call properties of (Anura, Hylidae) in response to different noise conditions.

The increasing expansion of urban areas leads to the emergence of new noisy environments that can affect animal communication. Calls play a crucial role in the mating displays of anurans, and the negative impact of anthropogenic noise-induced auditory masking has been reported in several species. We investigated the acoustic variation in 96 males (971 calls) of the treefrog across acoustically undisturbed sites and different noise conditions, associated with urban areas (URBAN) and roads (ROAD), in Central Argentina.

Hemoparasites Do Not Affect Life-History Traits and Cellular Immune Response in Treefrog Hosts .

We provide the first evidence for hemoparasites in the endemic Cordoba treefrog . We collected 37 adult frogs at 1200 m a.s.

Effect on growth and development of common toad (Rhinella arenarum) tadpoles in environment related to fluorite mine.

Fluorite mining activities have been scarcely evaluated so far and the potential effect of this activity on larval stages is poorly known. Thus, studies addressing the effect of contaminants present in water bodies on the health of amphibian larvae are crucial information for their conservation and constitute a warning sign of environmental modification. This study aims to evaluate the effects of natural and artificial surface waters associated with a fluorite mine on the early life stages of Rhinella arenarum.

Asymmetric Male Mating Success in Lek-Breeding .

Mate choice is the attempt of an individual to gain higher reproductive fitness by preferring to mate with some individuals and not with others. We studied the role of mate choice in the mating system of the neotropical toad by assessing male reproductive tactics for mate acquisition and the contribution of female choice for pair formation. In a shallow pond in central Argentina, we estimated male mating success and the corresponding reproductive tactics by focal observation.

Body size, age and growth in males populations of Boana pulchella (Anura, Hylidae).

Age determination in amphibians is crucial to the investigation of life-history traits. In this context, we studied, for the first time, the life-history traits of Boana pulchella from a sample (63 adult males) of three populations (Las Acequias, Río Cuarto, Alejandro Roca) in central Argentina using the skeletochronological method. All adults of B.
