Deep-sea mining generates plumes containing heavy metals harmful to marine ecosystems. Assessing their impact on benthic organisms is essential. Traditional monitoring methods commonly employ acoustic, optical, and electrical approaches to investigate collective behaviors of organisms, while direct acquisition and in situ preservation of biological specimens during deployment remain challenging. To address this limitation, a n...

We estimated, for the first time, the age of Diaphus watasei (Jordan & Starks, 1904) in the South China Sea (SCS) based on otolith microstructure. According to one-way ANOVA, differences were not observed between the sexes with regard to standard length, body mass, or age. Based on 137 specimens, the sex ratio and relationship between standard length and body mass was 1.32:1 (male/female) and W = 0.0000433L2.78 (r2 = 0.923), r...

As the northernmost locality yielding one of the most representative Early Pleistocene Gigantopithecus – Sinomastodon faunas in southern China, the Longgupo site has preserved valuable geological archives that have significantly improved our understanding of Pleistocene biostratigraphy and biogeography. A convincing chronological framework of this locality is therefore important to elaborate on the evolution of Quaternary faun...
