Animal songs can change within and between populations as the result of different evolutionary processes. When these processes include cultural transmission, social learning information or behaviours from conspecifics, undergo rapid evolutions because novelties emerge more frequently than genetic mutations. Understanding song variations over large temporal spatial scales provide insights into patterns, drivers limits evolution that ultimately inform on species' capacity to adapt rapidly...
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...
An increase in ocean noise levels could interfere with acoustic communication of marine mammals. In this study we explored the effects anthropogenic and natural on properties a dolphin signal, whistle. A towed array four elements was used to record environmental background whistles short-beaked common-, Atlantic spotted- striped-dolphins Canaries archipelago. Four frequency parameters were measured from each whistle, while Sound Pressure Levels (SPL) at central frequencies seven one-third...
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...
Abstract Acoustical geographic variation is common in widely distributed species and it already described for several taxa, at various scales. In cetaceans, intraspecific acoustic repertoires has been linked to ecological factors, geographical barriers, social processes. For the bottlenose dolphin ( Tursiops truncatus ), studies on variability are scarce, focus a single signal type—whistles influence of environmental variables. Here, we analyze emissions nine populations across Atlantic...
The Franciscana dolphin (Pontoporia blainvillei) is facing significant threats in the Southwestern Atlantic Ocean, largely due to entanglement artisanal fishing nets, which makes it most threatened species region Its conservation calls for a standardised methodology that enables detection and monitoring of populations on longer temporal scale. This study represents first acoustic wild dolphins Argentina, focusing understanding their diel patterns activity relationship with environmental...
The common bottlenose dolphin is a cosmopolitan species that can be found worldwide in all oceans except polar and sub-polar waters. This wide distribution associated with certain level of morphological variation, which seems consistent the presence globally distributed pelagic/offshore ecotype several coastal/inshore ecotypes along continental shelf. In Mediterranean Sea, regularly occurring second most sighted cetacean after striped dolphin. According to some studies, more closely related...
ABSTRACT The harbor porpoise ( Phocoena phocoena ) in the Atlantic waters of Spain and Portugal are a genetically differentiated population from rest North Atlantic. They rarely seen on southern coast thought to be extinct Mediterranean Sea, with scattered sightings strandings recorded along Spanish coast. Here, we present 35 live porpoises ~15 km coastline between Los Boliches (Fuengirola) Benalmádena Andalucia. data were collected whale watching vessels two distinct periods: 2011–2013...
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...
Geographic variation in the acoustic features of whistles emitted by striped dolphin (Stenella coeruleoalba) from Atlantic Ocean (Azores and Canary Islands) Mediterranean was investigated. Ten parameters (signal duration, beginning, end, minimum maximum frequency, number inflection points, steps, minima maxima contour frequency range) were extracted each whistle. Discriminant function analysis correctly classified 73% sounds between Sea. A cline apparent Azores to Mediterranean, with a major...
Since 2003, as part of the LIFE project ‘Del.Ta.’ (NAT/IT/000163) a bottlenose dolphin community has been studied in order to assess impact increasing boat traffic Pelagie Archipelago (Sicily, Italy). During summer 2006 and 2008, land-based surveys were carried out at Lampedusa, one Archipelago's Islands, set hours from 6 locations (7 2008) standard weather conditions. Continuous horizon scanning focal group sampling methods used study presence behaviour. Dolphin–boat interactions recorded...
Acoustic observation can complement visual to more effectively monitor occurrence and distribution of marine mammals. For effective acoustic censuses, calibration methods must be determined by joint studies. Research is still needed in the field species identification, particularly for smaller odontocetes. From 1994 2012, whistles four odontocete were recorded different areas Mediterranean Sea determine how reliably these vocalizations classified species. Recordings attributed simultaneous...
Abstract An understanding of the population dynamics and social organization cetaceans is essential to manage influence anthropogenic activities. In this study, size, site fidelity interactions bottlenose dolphins in Strait Sicily (Italy) were investigated provide recommendations for their conservation. Mark‐recapture analysis was based on encounter histories 103 marked from 2004 2015. The POPAN formulation Jolly–Seber model MARK software used estimate size super‐population. Site estimated...
Many gregarious species require complex patterns of communication for maintaining coordinated behaviors, articulated social structure and group cohesion. In mammal species, complexity has been considered the driving force development advanced acoustic systems. Striped dolphins are highly social, showing large size with females strong bonds kin. Here, we tested hypothesis that more pattern plays a key role in activity striped dolphins. The production rate clicks, whistles burst pulses,...
Periodic assessments of population status and trends to detect natural influences human effects on coastal dolphin are often limited by lack baseline information. Here, we investigated for the first time site-fidelity patterns estimated size bottlenose dolphins (Tursiops truncatus) at Tiber River estuary (central Mediterranean, Tyrrhenian Sea, Rome, Italy) between 2017 2020. We used photo-identification data metrics study tendency remain in, or return to, area, capture–recapture models...
The Arctic marine environment is highly affected by global warming with notable changes in habitat conditions, which have great consequences on migrating species. For example, the timing of their migration can be altered leading to occurrence suitable areas, are critical for survival. In this study, seven years acoustic data were analysed Svalbard Islands from 2014 2020, revealing that fin whales (Balaenoptera physalus) happened all year-round. sea surface temperature recorded reveals...
