We report first-time evidence of barrier feeding techniques in the population common bottlenose dolphin (Tursiops truncatus) at estuary Tiber River (Rome, Italy), used to prey on flathead grey mullet (Mugil cephalus). describe an event that occurred summer 2023, consisting dolphins forcing schools mullets against different types barriers, i.e. sea surface, coastal breakwater blocks and other dolphins. provide first visual acoustic account this predation modality Mediterranean Sea, showing...
Abstract Frequency modulation (FM) is believed to play a major role in encoding information tonal vocal communication. However, most studies aimed at investigating acoustic variability rely on the manual measurement of parameters, and implementation multivariate techniques, which represent only partially sound FM. Thus, innovative modelling approaches able capture local FM dynamics are needed for sounds modelling. These kinds methodological developments bioacoustics might be key further...
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...
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...
Acoustic sequences are commonly observed in many animal taxa. The vast vocal repertoire of common bottlenose dolphins (Tursiops truncatus) also includes multi-unit rhythmic signals called bray-call which still poorly documented, both functionally and geographically. This study aimed to (1) describe, classify, characterize series recorded two sites the Mediterranean basin (Rome-Tyrrhenian Sea Mazara del Vallo-Strait Sicily) (2) investigate for existence possible geographic differences....
Abstract One of the most studied aspects animal communication is acoustic repertoire difference between populations same species. While numerous studies have investigated variability bottlenose dolphin whistles populations, very few focused on signature alone and factors underlying differentiation are still poorly understood. Here we describe produced by six distinct geographical units common ( Tursiops truncatus ) in Mediterranean Sea identify main determinants their variability....
Epimeletic behavior toward dead calves has been frequently reported in cetaceans, mostly with females (presumed mothers) showing supportive behaviors such as carrying, lifting, or sinking, often assisted by "escort" individuals. However, information on acoustic production contexts is scarce. This report describes two observations of epimeletic newborns bottlenose dolphins and associated production. Data were collected at the Tiber River estuary (Rome, Mediterranean Sea, Italy) one hydrophone...
Sociality and ecological drivers that can influence individual association patterns are infrequently considered in wildlife management, although they essential aspects affecting animals’ responses to both human-related pressures conservation strategies. In common bottlenose dolphins ( Tursiops truncatus ), sex-specific social dynamics interactions with anthropogenic activities may affect grouping induce changes relationships between individuals. Out of a total 347 individuals, we assessed...

ABSTRACT The acoustic ecology of a previously unexamined dolphin population in the Mediterranean was assessed by investigating how sound emissions and features are influenced concurrent conditions. Whistles click‐trains emission rates were compared among different environmental, social behavioural Structural variability 3928 good/high‐quality vocalizations analysed relation to contexts through two‐stage approach. First, two multivariate MANOVA‐models fitted considering entire set parameters...
