Biodiversity as a Dominant Force in Shaping Ethnic Music Styles 生物多样性:塑造民族音乐风格的主导力量
Integrative Conservation, EarlyView.Our findings show that plant, bird, and mammal diversity considerably shape musical features such as vocal range and ornamental sounds, more so than geography or lifestyle. Our study provides the first empirical evidence linking biodiversity to ethnic music styles. Protecting biodiversity, the musical and cultural will be protected.

Integrative Conservation, EarlyView.Relatively little is known about the distribution or habitat requirements of Hong Kong's population of the Chinese pangolin. Between 2018 and 2021 we searched for pangolin burrows and deployed camera traps on the burrows. We then analyzed habitat suitability at multiple scales to determine the factors that are key in driving pangolin distributions in ...

Haiyang yu huzhao安氏新银鱼是我国重要的小型经济鱼类物种，具有较高的经济价值。但目前缺乏一种快速、经济有效的性别鉴定方法，极大地阻碍了其性别决定分子机制、性染色体演化历程的研究和水产育种与养殖技术方面的生产实践。本研究通过比较安氏新银鱼雌性与雄性的全基因组重测序数据，发现雌雄之间存在一个显著差异的基因组区域(chr02: 2 798 574~5 434 239 bp)。基于测序深度差异分析筛选得到3个雌性特异性片段，长度分别为10 bp、167 bp和53 bp。在长为167 bp的雌性特异性位点附近设计引物 ...
