A crucial, common feature of speech and music is that they show non-random structures over time. It an open question which the other species share rhythmic abilities with humans, but in most cases lack knowledge about their behavioural displays prevents further studies. Indris are only lemurs who sing. They produce loud howling cries can be heard at several kilometres, all members a group usually We tested whether overlapping turn-taking during songs followed precise pattern by analysing...
Chromis chromis is a key species in the Mediterranean marine coastal ecosystems where, summer, recreational boating and its associated noise overlap. Anthropogenic could induce behavioural modifications organisms, thereby affecting population dynamics. In case of an important for ecosystem like C. chromis, this rebound on community structure. Here, we measured nautical traffic during summer 2007 Southern Marine Protected Area (MPA) simultaneously feeding behaviour was video-recorded, within...

The growing concern for the ongoing biodiversity loss drives researchers towards practical and large-scale automated systems to monitor wild animal populations. Primates, with most species threatened by extinction, face substantial risks. We focused on vocal activity of indri (Indri indri) recorded in Maromizaha Forest (Madagascar) from 2019 2021 via passive acoustics, a method increasingly used monitoring activities different environments. first indris’ songs, loud distinctive sequences,...
We investigated the presence and diversity of cetaceans in Mediterranean Sea, analysing data collected by 32 different research units, over a period 15 years (2004–2018), shared on common web-GIS platform named Intercet. used encounter rate, species prevalence, Shannon index as parameters for analysis. The results show that cetacean diversity, context basin, is generally quite low when compared with eastern Atlantic, few species, namely striped dolphin, bottlenose fin whale, sperm dominate...
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...
Contextual variation in the loud calls of strepsirhine primates is poorly understood. To understand whether songs given by indris different contexts represent acoustically distinct variants and have potential to elicit context-specific behaviours conspecific listeners, we investigated acoustic variability these distance travelled vocalizers after their emissions. Songs 41 individuals were recorded from 16 indri groups four forest sites eastern Madagascar. We collected a total 270 duets...
Abstract Animal songs differ from calls in function and structure, have comparative translational value, showing similarities to human music. Rhythm music is often distributed quantized classes of intervals known as rhythmic categories. These been found the a few nonhuman species but never their calls. Are categories song‐specific, music, or can they transcend song–call boundary? We analyze vocal displays one mammals producing both call sequences: Indri indri . test whether (a) are conserved...
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...
5-hydroxy-N,N-dimethyltryptamine (5-OH-DMT), known as bufotenine, is proven to have psychoactive effects in high concentrations.

Two extraction protocols were applied depending on sample type...
In this study, we analysed the patterns of variation European treefrog’s advertisement call at four levels organization: within individuals, populations, among populations same species, and different species clade. At within‐individual level, acoustic properties are distinguished into static dynamic properties. within‐population two sources were analysed: temperature body size. Temperature affects both temporal spectral call. Body size mostly between‐population calls do not show significant...
Abstract The distribution of Bufo bufo, Rana esculenta complex, dalmatina, Hyla arborea, Triturus carnifex and vulgaris were studied in 61 ponds NW Italy, relation to a number specific habitat features. Multivariate analysis identifies those parameters which classify into characteristic groups. Several multivariate statistical tests carried out identify features each species delineate ecological factors that influence amphibian distributions size breeding populations. Variables scored at...
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...
Abstract Animal acoustic communication often takes the form of complex sequences, composed multiple distinct units, which can vary in their degree stereotypy. Studies sequence variation may contribute to our understanding structural flexibility primates' songs, provide essential ecological and behavioral information about variability at individual, population, specific level insights into mechanisms drivers responsible for evolutionary change communicative traits. Several methods have been...
Differences in body size between both species and sex were observed to be close Hutchinsonian ratios an assemblage of three newts (Triturus italicus, T alpestris carnifex) southern Italy According feeding, differences not related with a strict food niche segregation The diet larger newt included indeed all the prey eaten by smaller but showed new types more marked than sexes same species, despite strong sexual dimorphism Larger foraged wider range microhabitats exhibited greater diversity...
To determine how climate factors influence age, body size and sexual dimorphism (SSD) in the Mediterranean region, we generated data on age of European Treefrog, Hyla arborea , three Turkish populations with a latitudinal gradient. We estimated structure (total ), using skeletochronology. Mean both sexes was smaller southern population (Antalya) than northern (Çanakkale Rize) female-larger SSD populations. A positive correlation found between each sex all populations, save Antalya females....
