Influences on abundance, distribution, and morphology have been recorded at the species level. It has been found that climate change has a wide range of effects on natural systems. A growing number of studies have proved that the global climate is changing rapidly, with unexpected implications. ![]() Climate change can be more harmful to amphibians than other groups of vertebrates and is one of the major causes of the extinction of ectotherms. Frogs were more affected by high temperatures than by heat waves.Īmphibians are considered as an excellent study group to further improve our understanding of genomics, because they exhibit a wide range of reproductive strategies, occupy the majority of ecoregions on earth, have a highly diverse range of morphology, and are the most endangered group of vertebrates globally. ![]() Under both stress conditions, compromising the protection of HSP and sluggish steroid activity occurred in frogs. It might be strategic to preserve initiation to executive protein activity under heat wave stress. Genes were more transcriptionally suppressed when treated with high temperatures than heat waves, and the body stayed in low-energy states for combating these long-term adverse environments to survive. During heat waves, unlike the high-temperature group, mitochondrial function was not impaired, and the energy supply was largely normal to support the highly energy-consuming metabolic processes. Long-term exposure to high-temperature stress may impair the metabolic rate of the frog and trigger the body to maintain a hypometabolic state in an effort to survive challenging times. Notably, genes belonging to the heat shock protein ( HSP) family were down-regulated in both treated groups. Up to 694 genes were found to be differently regulated as a result of abnormal temperature acclimatization. A total of 126,465 unigenes were produced, with 66,924 (52.92%) of them being annotated. A liver transcriptome for Nanorana pleskei was constructed using high-throughput RNA sequencing, and its gene expression was compared with frogs acclimated under either room temperature or high temperature and also heat wave exposed ones. In the context of climate change, understanding how indigenous amphibians of the Qinghai-Tibet plateau react to stresses and their coping mechanisms could be crucial for predicting their fate and successful conservation.
