The study of marine soundscapes is an emerging field research that contributes important information about biological compositions and environmental conditions. seasonal circadian soundscape trends a protected area (MPA) in the Mediterranean Sea have been studied for one year using autonomous acoustic recorder. Frequencies less than 1 kHz are dominated by noise generated waves louder during winter; conversely, higher frequencies (4-96 kHz) snapping shrimp, which increase their activity at...
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...

The sperm whale (Physeter macrocephalus) emits a typical short acoustic signal, defined as "click", almost continuously while diving. It is produced in different time patterns to acoustically explore the environment and communicate with conspecifics. Each emitted click has multi-pulse structure, resulting from production of sound within whale's head. A Stable Inter Pulse Interval (Stable IPI) can be identified among pulses that compose single click. Applying specific algorithms, measurement...
Dolphins emit short ultrasonic pulses (clicks) to acquire information about the surrounding environment, prey and habitat features. We investigated Delphinidae activity over multiple temporal scales through detection of their echolocation clicks, using long-term Passive Acoustic Monitoring (PAM). The Istituto Nazionale di Fisica Nucleare operates multidisciplinary seafloor observatories in a deep area Central Mediterranean Sea. Ocean noise Detection Experiment collected data offshore Gulf...

Each is a mechanical structure anchored to sea floor, held vertical by submerged buoy and supporting optical modules for Cherenkov light emitted charged secondary particles emerging from interactions. This string implements three with 31 photomultiplier tubes each. These were developed...
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...
<title>Abstract</title> Passive Acoustic Monitoring (PAM) has become a widely used method to study cetaceans, especially for populations facing escalating threats from noisy human activities, including shipping traffic, fishing industry and marine constructions. Here, we conducted the first using an Autonomous Surface Vehicle (ASV) explore distribution acoustic behavior of cetaceans characterize anthropogenic sound sources in central Mediterranean Sea. A Wave Glider equipped with...
In recent years, an increasing number of surveys have definitively confirmed the seasonal presence fin whales (Balaenoptera physalus) in highly productive regions Mediterranean Sea. Despite this, very little is yet known about routes that species seasonally follows within basin and, particularly, Ionian area. The present study assesses for first time whale acoustic offshore Eastern Sicily (Ionian Sea), throughout processing 10 months continuous monitoring. recording vocalizations was made...
Acoustic noise levels were measured in the Gulf of Catania (Ionian Sea) from July 2012 to May 2013 by a low frequency (< 1000 Hz) hydrophone, installed on board NEMO-SN1 multidisciplinary observatory. is cabled node EMSO-ERIC, which was deployed at water depth 2100 m, 25 km off Catania. The study area characterized proximity mid-size harbors and shipping lanes. Measured correlated with passage ships tracked dedicated AIS antenna. Noise power range between 10 Hz Hz. Experimental data compared...
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...

The ambient acoustic environment, or soundscape, is of broad interest in the study marine ecosystems as both a source rich sensory information to organisms and, more broadly, driver structure and function communities. Increasing our understanding how soundscapes affect reflect ecological processes first requires appropriate characterization stimuli, their patterns space time. Here, we present novel method developed for measuring soundscape variation, using drifting recorders quantify...
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...
The Indo-Pacific humpback dolphin (IPHD, Sousa chinensis) is a coastal species inhabiting tropical and warm-temperate waters. presence of this vulnerable was recently discovered in shallow waters southwest Hainan Island, China. influence the acoustic habitat on distribution behavior IPHD investigated using an array passive platforms (n = 6) that spanned more than 100 km coastline during 75-day monitoring period. Its assessed within 19 215 five-min recordings by classifying echolocation...
The northern Chilean Patagonia region is a key feeding ground and nursing habitat in the southern hemisphere for blue whales (Balaenoptera musculus). From 2014 to 2019, during 6 separate research cruises, dive behavior of 28 individual was investigated using bio-logging tags (DTAGs), generating ≈190 h data. Whales dove significantly greater depths day compared nighttime (day: 32.6 ± 18.7 m; night: 6.2 2.7 P < 0.01). During night, most time spent close surface (86% 9.4%; 0.01) at less than 12...

Abstract When implementing conservation strategies involving passive acoustic monitoring, an accurate description of signal properties is crucial, especially when studying threatened and elusive vocalizing species. Misrepresentation detected sounds can result in information loss or misclassification species, thus compromising the management process. Distortion time–frequency features depends on characteristics propagation through sea water, sensitivity sampling frequency acquisition system...

Despite risking being subjected anthropogenic impacts such as water contamination, marine traffic, and underwater noise, estuaries have been identified the preferred habitat of Indo‐Pacific humpback dolphin ( Sousa chinensis , IPHD). However, it remains unclear why this vulnerable species favours risky habitats. Here, an exploratory case study in Zhanjiang estuary, China, was...
