Comparative studies of vocal repertoires over the geographical range of a species can improve our understanding of the function and evolution of animal vocalizations. They may also help to elucidate relationships between populations, where genetic studies are missing or difficult to perform. We recorded male bearded seal vocalizations from four sites throughout their Arctic distribution. We measured 16 parameters for each vocalization and examined variability using classification tree analyses… Expand
Bearded seal males perceive geographic variation in their trills
TLDR
This study provides the first experimental evidence that phocid males can perceive geographic variation in their vocalisations, and may provide information on both strength and scale of breeding site fidelity in this and potentially other species. Expand
Bearded seal (Erignathus barbatus) vocalizations across seasons and habitat types in Svalbard, Norway
TLDR
Seasonal variation in the acoustic presence of male bearded seals and the phenology of different call types (long, step and sweep trills) at three sites representing a variety of habitats with varied ice conditions are investigated. Expand
Variation in pika ( ochotona collaris, o. princeps ) vocalizations within and between populations
TLDR
Geographic call variation in these two species of pikas likely reflects genetic divergence, and may be a result of separate evolutionary histories, and the potential for individual coding for both time and frequency measurements of calls was calculated. Expand
Temporal and spatial variation in harbor seal (Phoca vitulina L.) roar calls from southern Scandinavia.
TLDR
There was a strong seasonality in the calls from end of June to early August, with an activity peak at night, and large geographic variations were obvious in the total duration of the so-called roar call, theduration of the most prominent part of the call, and of percentage of energy in roar burst.

Geographic vocal variation and perceptual discrimination abilities in male Australian sea lions
TLDR
Investigation of whether males can discriminate local from non-local barks in Australian sea lions found that males responded more strongly to barks from their own colony compared tobarks from other colonies regardless of whether those other colonies were close or distant. Expand
Vocalizations of bearded seals ( Erignathus barbatus ) and their influence on the soundscape of the western Canadian Arctic

Quantitative classification of harbor seal breeding calls in Georgia Strait, Canada.
TLDR
It is suggested that the vocal repertoire of harbor seals in this area comprises a vocal continuum rather than discrete call types, and further work with the ability to localize calls may help to determine whether this complexity represents variability due to propagation conditions, animal orientation, or differences among individual seals. Expand
Geographic variation in vocalizations of pups and mother-pup behavior of harp seals Pagophilus groenlandicus
TLDR
Investigation of variation in mother-pup behavior between harp seal breeding aggregations in the NE (Greenland Sea) and NW Atlantic coastal shelf region (Front) found substantial differences between sites, which might be related to evolutionary changes in behavior resulting from commercial hunting or vari- able environmental conditions. Expand
Call characteristics of high-double trill leopard seal (Hydrurga leptonyx) vocalizations from three Antarctic locations
Leopard seals (Hydrurga leptonyx) produce underwater vocalizations during the breeding season in austral summer. Due to their solitary oc currence and remote habitat, hydroacoustic observations areExpand
Geographic variation in Northwest Atlantic fin whale (Balaenoptera physalus) song: implications for stock structure assessment.
TLDR
Song structure analysis could provide a useful and cost-efficient tool for defining conservation units over temporal and geographical scales relevant to management objectives in fin whales. Expand

Underwater vocalizations of the bearded seal (Erignathus barbatus)
TLDR
The results suggest that bearded seals may be relatively sedentary and that geographically different vocal repertoires may be characteristic of discrete breeding stocks. Expand
Patterns in the vocalizations of male harbor seals.
TLDR
Comparative analyses of the roar vocalization of male harbor seals from ten sites throughout their distribution showed that vocal variation occurs at the oceanic, regional, population, and subpopulation level, and these factors suggest that site-specific variation influences the development of vocal structure in harbor seals. Expand
Variation of harp seal (Pagophilus groenlandicus) underwater vocalizations among three breeding locations
TLDR
T tagging studies indicate that the Gulf and Front herds may be interbreeding and both are reproductively isolated from the Jan Mayen herd, and there is no evidence of acoustic adaptation to the site-specific ice and environmental conditions associated with the three study locations. Expand
Spatial and Temporal Distribution of Vocalising Maile Bearded Seals - Implications for Male Mating Strategies
TLDR
The spatial and temporal patterns of male bearded seal vocalisations were studied in Kongsfjorden, Svalbard from April 1999 to the end of May 2000 and it is suggested that male distribution may reflect the unpredictable nature of female distribution. Expand
Geographical variation of harp seal underwater vocalizations
TLDR
Underwater vocalizations of harp seals were recorded during the breeding season in the Gulf of St. Lawrence and north of Jan Mayen Island, indicating that the two herds are reproductively isolated. Expand
Vocalizations and movements suggest alternative mating tactics in male bearded seals
TLDR
The data on underwater vocalizations and movements of male bearded seals thus provide evidence for the use of alternative mating tactics in this species and suggest that trill duration may be a useful indicator of male ‘quality’. Expand
DEVELOPMENT OF DISPLAY BEHAVIOR IN YOUNG CAPTIVE BEARDED SEALS
TLDR
Individual capacity for vocal production appears to develop gradually, showing plasticity in form development over time in captive bearded seals. Expand
Variations in underwater vocalizations of Weddell seals (Leptonychotes weddelli) at the Vestfold Hills as a measure of breeding population discreteness
Weddell seal vocalizations from Davis Station showed similarities to those from McMurdo Sound and Palmer Peninsula, but none were identical. One vocalization, DD1, was unique to Davis Station. At allExpand
Long-term mating tactics in an aquatic-mating pinniped, the bearded seal, Erignathus barbatus
TLDR
It appears that although males can alter their mating tactics as circumstances change, only a few do so and mating tactics tend to show long-term stability in vocal characteristics, strong site fidelity and periods of tenure that cover a significant proportion of the male's adult life span. Expand
Geographic variation in the underwater vocalizations of Weddell seals (Leptonychotes weddelli) from Palmer Peninsula and McMurdo Sound, Antarctica
TLDR
Geographically different vocal repertoires have potential for identifying discrete breeding stocks of Antarctic seals and include strong fidelity to breeding sites, a polygynous mating system, and learning. Expand
