Beibu Gulf’s (BBG) Indo-Pacific humpback dolphins present both a genetic differentiation and phenotypical differences from conspecifics other areas of the South China Sea. Given recent urbanization industrialization in southern China, BBG warrant conservation attention. However, this population’s demographic trend is unclear, making it hard to take measures. To assess population status BBG, photo-identification surveys were conducted between 2015 2019 inshore region surrounding Dafeng River...
Abstract Indo‐Pacific humpback dolphins ( Sousa chinensis ) inhabiting the Chinese coastline of northern South China Sea are subject to intense human activity. To investigate potential impacts dolphins, photographs taken from 2010 2021 in five different locations were analyzed. Among individual N = 1,159), 10.6% presented human‐induced injuries. Adults more frequently injured than young and individuals around Jiangmen, Hainan, Sanniang Bay highest injury prevalence. More research should be...
Abstract Indo‐Pacific humpback dolphins form a resident population off the east coast of Leizhou Peninsula (LZP) in South China. The most recent study suggested ~1,500 individuals this area, making one only two populations species exceeding 1,000 individuals. However, demographic information regarding has been lacking since 2012. Using 5‐year (2019–2023) photo‐identification data set, we examined key parameters LZP population, namely apparent survival and size, using multistate...
Abstract Beaked whales have recently been reported in the South China Sea but with taxonomic uncertainty due to their ambiguous morphological features. Here, we sequenced three genetic markers, control region (CR) and cytochrome b ( cytb ) of mitochondrial genome first intron nuclear muscle actin gene ACTA2 , two biopsy samples collected 2021, revealed unambiguous clustering sequences previously attributed Deraniyagala's beaked whale Mesoplodon hotaula ). Phylogenetic analysis complete...
Fishing activities result in a depletion of fish resources and an increase bycatch probability non-target species, which are thought to be the cause recent demographic change experienced by coastal cetaceans waters off Guangdong province, China. However, fishing intensity its spatiotemporal pattern remain poorly examined this region. Here, random daily tracks from 100 vessels were used estimate operations province. The performance two methods was tested with Automatic Identification System...

Abstract Deraniyagala's beaked whale, Mesoplodon hotaula , was previously known from eight published strandings and no confirmed live sightings, making it one of the least‐known cetaceans. We conducted six cetacean survey cruises in South China Sea between 2019 2023, during 120 sea‐days we recorded 12 sightings unidentified . From biopsy samples acoustic recordings, five were subsequently as M. hotaula. Using photographs, provide first field descriptions observations this species. The...
Satellite-tagging is increasingly becoming a powerful biotelemetry approach to obtain remote measurement through tracking free-living cetaceans, which can fill knowledge gaps on cetaceans and facilitate conservation management. Here, we made first biologging attempt baleen whales in Chinese waters. An adult Bryde’s whale the Beibu Gulf was tagged investigate potential occurrence areas migration routes of this poorly studied species. The satellite-tracked for ~6 days with 71 filtered Argos...
Abstract Tooth rake marks are usually used as an indicator of received aggression in odontocetes whose social interactions difficult to observe directly. Photographic data from five locations the northern South China Sea were analyze seasonal, demographic, and geographic effects on density tooth dorsal fin notches Indo‐Pacific humpback dolphins ( Sousa chinensis , IPHDs). The analysis revealed that fresh most frequent during dry season. Males exhibited significantly higher mark than females...
<title>Abstract</title> Indo-Pacific humpback dolphins (<italic>Sousa chinensis</italic>) typically inhabit turbid coastal waters and estuaries, making it hard to observe their behaviour. Therefore, until now, only a few studies have provided descriptions of this species’ Studying foraging behaviours is needed better understand the tactics adopted by species inform conservation measures. This study aimed describe quantify displayed in three different locations northern South China Sea,...
The South China Sea is a crucial habitat and potential nursery for cetaceans. This study involved five ship-based visual surveys in three summers two springs from 2020 to 2023, combined with environmental DNA (eDNA) metabarcoding, an emerging tool, understand the relative abundance spatial temporal distribution of cetaceans offshore abyssal areas Sea. combination observations eDNA metabarcoding enabled detection total 18 cetacean species, 12 species were identified by both methods. Cetaceans...
Ferula diversifolia W.Jun Li & Lei Yang, is described and illustrated from Xinjiang Province, China. The new species morphologically similar to F. foetidissima Regel Schmalh. in terms of its garlic‐like odor, robust stem, characetristic branching pattern with a paniculate inflorescence. However, it distinctly different ternate‐2‐pinnate compound leaves much broader shorter leaflets that are incised‐elliptical rhombic shape, significantly smaller fruits. diagnosis the supported by...
Indo-Pacific humpback dolphins (IPHDs) who form resident populations along the Chinese coastline are facing a wide range of anthropogenic disturbances including intense fishing and some have been shown to experience severe decline. Body condition is thought be good indicator health since it linked survival reproductive success. In order better understand population trends, we investigated whether body IPHDs poorer in whose status alarming than other populations. UAV flights were conducted...
The Indo-Pacific humpback dolphin is characterized by a particular ontogenic change in body color from dark gray at birth to pure white (or with few dark-gray spots) after reaching adulthood. Here, we report spectrum of anomalous patterns observed on dolphins off southern China. occurrence hypopigmentation and hyperpigmentation was described compared among six putative populations. Low rates anomalies were (<1%), except for hypopigmentation, which prevalent residing the...
