ABSTRACT Aim The urgency for remote, reliable and scalable biodiversity monitoring amidst mounting human pressures on ecosystems has sparked worldwide interest in Passive Acoustic Monitoring (PAM), which can track life underwater land. However, we lack a unified methodology to report this sampling effort comprehensive overview of PAM coverage gauge its potential as global research tool. To address gap, created the Worldwide Soundscapes project, collaborative network growing database...
Significance Divergent lineages can respond to common environmental factors through convergent processes involving shared genomic components or pathways, but the molecular mechanisms are poorly understood. Here, we provide resources and insights into evolution of mammalian adapting aquatic life. Our data suggest evolution, for example, in association with thermoregulation genes associated a surface heat barrier ( NFIA ) internal exchange SEMA3E ). Combined support previous reports showing...
Abstract The urgency for remote, reliable, and scalable biodiversity monitoring amidst mounting human pressures on climate ecosystems has sparked worldwide interest in Passive Acoustic Monitoring (PAM), but there been no comprehensive overview of its coverage across realms. We present metadata from 358 datasets recorded since 1991 above land water constituting the first global synthesis sampling spatial, temporal, ecological scales. compiled summary statistics (sampling locations, deployment...
Abstract The Yangtze finless porpoise ( Neophocaena asiaeorientalis ) is an endangered freshwater subspecies unique to the River basin. Seasonal variations in local distribution of animal, as well fish presence, sand dredging, ship navigation, and bridges were examined potential factors affecting occurrence animals. Passive acoustic surveys performed regularly from May 2007 August 2010, near conjunction Poyang Lake. porpoises was seasonally site‐specific. In August, animals detected more...
Passive Acoustic Monitoring (PAM) is increasingly being adopted as a non-invasive method for the assessment of ocean ecological dynamics. PAM an important sampling approach acquiring critical information about marine mammals, especially in areas where data are lacking and evaluations threats vulnerable populations required. The Indo-Pacific humpback dolphin (IPHD, Sousa chinensis) coastal species which inhabits tropical warm-temperate waters from eastern Indian Ocean throughout Southeast...
In Yangtze finless porpoises Neophocaena phocaenoides asiaeorientalis, the effects of fatiguing noise on hearing thresholds at frequencies 32, 45, 64, and 128 kHz were investigated. The parameters were: 0.5-oct bandwidth, −1 to +0.5 oct relative test frequency, 150 dB re 1 μPa (140–160 in one measurement series), with 1–30 min exposure time. Thresholds evaluated using evoked-potential technique allowing tracing threshold variations a temporal resolution better than min. most effective was...
Abstract During the Yangtze Freshwater Dolphin Expedition 2012, finless porpoises ( Neophocaena asiaeorientalis ) were acoustically monitored in 9 port areas at night. 6566 min of nocturnal monitoring, porpoise sonar was detected for 488 (7.43% total time). Of all 81 encounters, longest echolocation span obtained 102.9 min, suggesting frequent and prolonged occupation areas. A combined 2091 click trains recorded, with 129 (6.2%) containing minimum inter‐click intervals (ICIs) below 10 ms...
A method is presented to estimate the density of finless porpoises using stationed passive acoustic monitoring. The number click trains detected by stereo data loggers (A-tag) was converted an porpoises. First, automated off-line filter developed detect a train among noise, and detection false-alarm rates were calculated. Second, estimation model proposed. cue-production rate measured biologging experiments. probability detecting cue area size calculated from source level, beam patterns,...
Abstract A pioneering boat‐based survey was conducted in 2019, to gather baseline information regarding the presence, composition, relative abundance, and spatial distribution of deep‐diving off‐shore cetaceans northern South China Sea (SCS). total 27 sightings comprising at least 8 cetacean species were recorded during 13‐day survey, including 5 (i.e. Risso's dolphin [ Grampus griseus ], short‐finned pilot whale Globicephala macrorhynchus sperm Physeter macrocephalus Cuvier's beaked Ziphius...
Abstract Deraniyagala's beaked whale ( Mesoplodon hotaula ) is one of the least‐known species, with only a few possible live sightings being documented to date. Here, vocalizations whales were recorded using drifting recording systems in confirmed presence this northern South China Sea (SCS) 2021. A total 699 qualified frequency‐modulated (FM) pulses used calculate frequency and duration measurements. FM had median peak 43.3 kHz interpulse interval (IPI) 244.6 ms. Both spectra measurements...
Abstract Poyang Lake is the largest freshwater lake in China and flows into Yangtze River. It a traditional habitat for endangered finless porpoise, which has not been well investigated. To reveal distribution of porpoise Lake, 12 passive acoustic surveys were conducted along 123 km main channel during different seasons (spring transition season, wet autumn dry season) from 2008 to 2012. We counted number phonating porpoises encountered calculated detection rate (encountered individuals...
The Indo-Pacific humpback dolphin (Sousa chinensis) is a small inshore species of odontocete cetacean listed as Vulnerable on the IUCN Red List. Here, we report evolution S. chinensis chromosomes from its cetruminant ancestor and elucidate evolutionary history population genetics two neighboring populations. We found that breakpoints in ancestral leading to could have affected function genes related kidney filtration, body development, immunity. Resequencing individuals populations...
The Yangtze finless porpoise (Neophocaena asiaeorientalis ssp. asiaeorientalis) is a subspecies of the narrow-ridged (N. asiaeorientalis). In total, 714.28 gigabases (Gb) raw reads were generated by whole-genome sequencing porpoise, using an Illumina HiSeq 2000 platform. After filtering low-quality and duplicated reads, we assembled draft genome 2.22 Gb, with contig N50 scaffold values 46.69 kilobases (kb) 1.71 megabases (Mb), respectively. We identified 887.63 Mb repetitive sequences...
In order to screen the candidate genes of Fenneropenaeus chinensis related low-temperature tolerance, this research takes juvenile prawns F. (P40) in low temperature stress group (4°C) and normal (18°C) as experimental materials. The results showed that a total 127,939 Unigenes with average length 1,190 bp were obtained by assembly, which 46% annotated Nr database. A 1,698 differentially expressed screened differential gene expression analysis, 920 up-regulated 778 down-regulated expression....
Abstract Beaked whales represent around 25% of known extant cetacean species, yet they are the least all marine mammals. Identification many Mesoplodon species has relied on examination a few stranded individuals. Particularly, ginkgo‐toothed beaked whale ( ginkgodens ) and Deraniyagala's hotaula among least‐known without confirmed sightings living individuals to date. We present sighting 3 free‐ranging M. ginkgodens/hotaula from dedicated mammal vessel survey carried out in South China Sea...
