B-chromosomes in two Brazilian populations of Dendropsophus nanus (Anura, Hylidae) [PDF]

open access: yesGenetics and Molecular Biology, 2006
We report on the presence of B-chromosomes in two populations of Dendropsophus nanus (= Hyla nana Boulenger, 1889) from São Paulo State, Brazil. Such chromosomes were observed in 4 out of 43 specimens (9.3%) and in 9 out of 15 specimens (60%) from the ...

Five Independent Lineages Revealed by Integrative Taxonomy in the Dendropsophus nanus–Dendropsophus walfordi Species Complex [PDF]

open access: yesDiversity, 2021
One of the many taxonomic challenges found in the Dendropsophus microcephalus species group is the Dendropsophus walfordi distinction from D. nanus. Recent phylogenetic inferences have indicated the paraphyly of these species, although they were not ...

Suction Feeding in Dendropsophus cerradensis Tadpoles: New Behavioral Observations and Morphological Traits in a Member of the D. microcephalus Group (Anura, Hylidae). [PDF]

open access: yesJ Morphol
The tadpole of Dendropsophus cerradensis exhibits an oral tube completely covered by external folds. The feeding behavior is characterized by an oral tube that protrudes exclusively during predation. This macrophagy feeding is associated with a buccopharyngeal cavity reduced in features, robust mandibular and hyoid musculature, as well as a modified ...

Temporal Dynamics of Species Richness and Composition in a Peri-Urban Tropical Frog Community in Central Brazil. [PDF]

open access: yesEcol Evol
This study address how species coexistence and species–environment relationship are impacted by temporal variation in climate sub‐urban area. ABSTRACT Analyzing the temporal dynamics of ecological communities can shed light on coexistence mechanisms and help understand how populations and communities will behave in the face of climate change.

Climatic variables influence the temporal dynamics of an anuran metacommunity in a nonstationary way. [PDF]

open access: yesEcol Evol, 2020
Using a multivariate method called STATICO, we described the stable patterns and the temporal changes of the relationship between species composition and the climatic variables. The metacommunity showed a weak synchronous spatial pattern, meaning that species responded independently to environmental variation.

Geographic Variation in the Acoustic Signals of Dendropsophus nanus (Boulenger 1889) (Anura: Hylidae)

open access: yesHerpetologica, 2020
Anurans communicate information during breeding activity to conspecifics mainly through acoustic signals, and different evolutionary forces may produce geographic variation in such communication systems. To understand which variables influenced geographic variation in the advertisement call of Dendropsophus nanus, a generalist species with a broad ...

Advertisement and courtship calls of Dendropsophus nanus (Boulenger, 1889) (Anura: Hylidae) from its type locality (Resistencia, Argentina) [PDF]

open access: yesBiota Neotropica, 2016
Abstract Dendropsophus nanus was described from Resistencia, Argentina. The species distribution is widespread in South America east of the Andes. Despite its wide distribution, little information about its advertisement call is available in the literature.

HELMINTOS DE CHIASMOCLEIS ALBOPUNCTATA (BOETTGER, 1885) (ANURA: MICROHYLIDAE) Y DENDROPSOPHUS NANUS (BOULENGER, 1889) (ANURA: HYLIDAE) EN CERRADO, SURESTE DEL BRASIL

open access: yesNeotropical Helminthology, 2019
Brasil es el país con la mayor riqueza de anfibios del mundo con alrededor de 1.136 especies descritas, de las cuales 1.093 son anuros. Sin embargo, los estudios relacionados sobre el conocimiento de la fauna de helmintos asociados son escasos, y representan solo el 8% de los anuros.
