Update on Distribution and Conservation Status of Amphibians in the Democratic People’s Republic of Korea: Conclusions Based on Field Surveys, Environmental Modelling, Molecular Analyses and Call Properties

open access: yesAnimals, 2021
Determining the range, status, ecology and behaviour of species from areas where surveys and samplings are uncommon or difficult to conduct is a challenge, such as in the Democratic People’s Republic of Korea (DPR Korea).

Delineating the anuran axial skeleton

open access: yesThe International Journal of Developmental Biology, 2021
The axial skeleton of the anurans has undergone an evolutionary reduction of its bone elements. This structural plan is strongly preserved throughout the order and would have emerged as a highly specialized anatomical adaptation to its locomotor jumping pattern.

What the largest tadpole feeds on? A detailed analysis of the diet composition of Pseudis minuta tadpoles (Hylidae, Dendropsophini)

open access: yesAnais da Academia Brasileira de Ciências, 2016
We analyzed the diet of 25 individuals of Pseudis minuta tadpoles which consisted in debris with more than 30%, follow by diatoms, euglenids, green algae, and desmids. With regard to the feeding strategy, P. minuta tadpoles are generalist consumer.

Detection of anuran calling activity in long field recordings for bio-acoustic monitoring [PDF]

open access: yes, 2015
This paper presents a system to analyze long field recordings with low signal-to-noise ratio (SNR) for bio-acoustic monitoring. A method based on spectral peak track, Shannon entropy, harmonic structure and oscillation structure is proposed to ...

The island rule in the Brazilian frog Phyllodytes luteolus (Anura: Hylidae): incipient gigantism?

open access: yesZoologia (Curitiba), 2015
The island rule suggests that, when mainland animals are isolated on islands, large animals tend to become smaller, while small animals tend to become larger.

Revisiting the drivers of acoustic similarities in tropical anuran assemblages [PDF]

open access: yes, 2021
Acoustic signaling is key in mediating mate-choice, which directly impacts individual fitness. Because background noise and habitat structure can impair signal transmission, the acoustic space of mixed-species assemblages has long been hypothesized to ...

Identification key for anuran amphibians in a protected area in the northeastern Atlantic Forest

open access: yesPapéis Avulsos de Zoologia, 2021
The identification of anuran amphibians is still a challenge in megadiverse assemblages. In the Neotropics, the Atlantic Forest harbors more than 600 anuran species, and many studies in this ecoregion report anuran assemblages surpassing 30 species ...
