A Review of the Scale and Sustainability of the Consumption and Trade of Anuran Species in Africa [PDF]

open access: yesEcology and Evolution
Within Africa, collection and trade of anurans is often recorded as single‐site case studies, making it difficult to accurately understand the scale of use, its livelihood importance, and impact on species.

Application of eDNA Metabarcoding for Detecting Anura on a Tropical Island

open access: yesDiversity, 2021
As anuran biodiversity quickly declines, it is important to understand local patterns of anuran occurrence. However, the limitations of traditional sampling methods make anuran biodiversity surveys inadequate.

Amphibian-Friendly Water Drainages for Agricultural Landscapes, Based on Multiple Species Surveys and Behavioural Trials for Pelophylax nigromaculatus

open access: yesDiversity, 2022
Amphibians are the most threatened vertebrate group on earth, and one of the reasons for their decline is habitat loss. While some populations have persisted in agricultural wetlands such as rice paddies, the current anthropisation of landscapes is ...

Temporally-aware algorithms for the classification of anuran sounds [PDF]

open access: yes, 2018
Several authors have shown that the sounds of anurans can be used as an indicator of climate change. Hence, the recording, storage and further processing of a huge number of anuran sounds, distributed over time and space, are required in order to ...

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).
