Fin Whales, Balaenoptera physalus: At Home in a Changing Mediterranean Sea?
Dispersal of North Atlantic fin whales (Balaenoptera physalus) into the Mediterranean Sea and exchange between populations: response to Giménez et al., Rapid Commun. Mass Spectrom. 2013, 27, 1801-1806.
The authors have ignored or misinterpreted the acoustic results presented by Castellote et al. (2012) and conclude that North Atlantic whales penetrate into the Mediterranean basin up to the northernmost latitudes of the region and that the border between the two putative subpopulations may not be as definite as previous acoustic investigations suggested.

Annual Acoustic Presence of Fin Whale (Balaenoptera physalus) Offshore Eastern Sicily, Central Mediterranean Sea
The study confirms the hypothesis that fin whales are present in the Ionian Sea throughout all seasons, with peaks in call detection rate during spring and summer months, and demonstrates that calls were more frequently detected in low background noise conditions.
Fin Whale (Balaenoptera physalus) in the Ligurian Sea: Preliminary Study on Acoustics Demonstrates Their Regular Occurrence in Autumn
The patterns of movement of the fin whale (Balaenoptera physalus (Linnaeus, 1758)) in the Mediterranean Sea are still a matter of debate. Feeding aggregations are well known in the

Acoustic divergence between bottlenose dolphin whistles from the Central–Eastern North Atlantic and Mediterranean Sea
To improve our understanding of the complex genetic and ecological structure of bottlenose dolphin (Tursiops truncatus) populations, we examined the acoustic features of communication signals from
Seasonal and geographical patterns of fin whale song in the western North Atlantic Ocean.
The temporal variability of INI may be a mechanism by which fin whale individuals encode and communicate a variety of behaviorally relevant information.
Synchronous Seasonal Change in Fin Whale Song in the North Pacific
The broad geographic and seasonal occurrence of this particular fin whale song type may represent a single population broadly distributed throughout the eastern Pacific with no clear seasonal migratory pattern.
Ship Strike Risk for Fin Whales (Balaenoptera physalus) Off the Garraf coast, Northwest Mediterranean Sea
Ship strikes are a widespread conservation issue for many cetacean species globally. Population level impacts depend on the occurrence and severity of collisions, which may lead to life altering


The fin whale Balaenoptera physalus (L. 1758) in the Mediterranean Sea
Based on genetic studies, fin whales from the Mediterranean Sea are distinct from North Atlantic conspecifics, and may constitute a resident population, separate from those of the North Atlantic, despite the species' historical presence in the Strait of Gibraltar.
Geographic variation in Northwest Atlantic fin whale (Balaenoptera physalus) song: implications for stock structure assessment.
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.
Distribution and abundance of fin whales (Balaenoptera physalus) in the western Mediterranean sea during the summer
P patterns of distribution of whales, with remarkably high densities in the feeding grounds, and composition of schools, which were found to be smaller than in other regions, suggest that food resources for the species in the north-western Mediterranean feeding grounds occur at higher densities but are more patchily distributed than inother fin whale feeding grounds so far studied.
Population genetic structure of North Atlantic, Mediterranean Sea and Sea of Cortez fin whales, Balaenoptera physalus (Linnaeus 1758): analysis of mitochondrial and nuclear loci
The results suggest the existence of several recently diverged populations in the North Atlantic and Mediterranean Sea, possibly with some limited gene flow between adjacent populations, a population structure which is consistent with earlier population models proposed by Kellogg, Ingebrigtsen, and Sergeant.
Blue and fin whale acoustic presence around Antarctica during 2003 and 2004
Seasonal and spatial variations of blue (Balaenoptera musculus) and fin whale (B. physalus) calls were analyzed from recordings collected with Acoustic Recording Packages (ARPs) deployed between
Singing behavior of fin whales in the Davis Strait with implications for mating, migration and foraging.
A negative correlation between the advancing sea ice front and power in fin whale frequencies indicates that future changes in sea ice conditions from global warming might change the distribution and migratory patterns of fin whales near the poles.
Biogeographic characterization of blue whale song worldwide: Using song to identify populations
Blue whale songs provide a measure for characterising worldwide blue whale population structure and it is suggested that temporally stable differences in song provide another characteristic for comparison with genetic and morphological data when defining blue whale populations.
Logbooks (n = 317) from whaling expeditions made in the North Atlantic during the 19th century were examined to investigate activity in the Gibraltar Straits grounds. At least forty expeditions of
Distribution, abundance and seasonality of cetaceans sighted during scheduled ferry crossings in the central Tyrrhenian Sea: 1989–1992
Stenella coeruleoalba, the most frequently observed species, are present all year round with no significant seasonal differences, in agreement with the hypothesis of a resident population making seasonal migrations around, but remaining inside the Mediterranean Sea.
Group-specific dialects and geographical variation in coda repertoire in South Pacific sperm whales
Sperm whales now join killer whales (Orcinus orca) as the only cetacean species in which dialects (differences in vocal repertoire among neighboring, potentially interacting groups) have been found.
