Quasipaa boulengeri, an Asian spiny frog that belongs to Neobatrachia, has been reported as a de novo case of chromosomal rearrangements. In this paper, we determined the whole mitochondrial DNA (mtDNA) sequence of Q. boulengeri. The complete mtDNA sequence of Q. boulengeri is 17,741 bp in length, which contains 13 protein-coding genes (PCGs), two rRNAs, 23 tRNAs and one control region. The overall nucleotides base composition of the complete mtDNA is A (28.86%), G (14.43%), C (26.09%), T (30.62%), with a much higher A + T content. Compared to other Neobatrachia species, the mtDNA genome of Q. boulengeri shows a novel gene order at WANCY region.

Background: Climatic and geographic variations have profound effects on the resource utilization of individuals and populations. Evaluating resource use in different environments is crucial for understanding species ecological adaptation strategies and promoting biodiversity conservation. Stable isotopes are widely used to assess trophic niches, providing quantitative indicators of ecological interactions between organisms and resource use in ecosystems.

Random forest (RF) and MaxEnt models are shallow machine learning approaches that perform well in predicting species' potential distributions. RF models can produce robust results with the default automatic configuration in most cases, but it is necessary for MaxEnt to optimize the model settings to improve the performance, and the predictive performance difference between optimized MaxEnt and RF is uncertain. To explore this issue, the potential distribution of the endangered amphibian Quasipaa boulengeri in China was predicted using optimized MaxEnt and RF models.

We used genotyping-by-sequencing (GBS) to identify sex-linked markers in 43 wild-collected spiny frog () adults from a single site. We identified a total of 1049 putatively sex-linked GBS-tags, 98% of which indicated an XX/XY system, and finally confirmed 574 XY-type sex-linked loci. The sex specificity of five markers was further validated by PCR amplification using a large number of additional individuals from 26 populations of this species.

Amphibians are particularly vulnerable to climate changes that are expected to cause habitat fragmentation and loss and, ultimately, local extirpations. However, little is known about how the interaction between climate change and fragmentation may impede the ability of amphibians to adapt to climate change. Here, we used the iconic mountain frog Quasipaa boulengeri as an indicator species to extrapolate climate-driven shifts in its habitat availability and connectivity in central and southern China according to the minimum and maximum representative concentration pathways.
