Mitochondrial DNA diversity, differentiation and phylogeography of the South American riverine and coastal dolphins Sotalia fluviatilis and Sotalia guianensis.

Latin American Journal of Aquatic Mammals, 2010
Here we consider the phylogeography and population structure of the South American coastal and riverine dolphins, Sotalia guianensis and Sotalia fluviatilis, based on samples (n = 76) collected across more than 9000km of the species distribution.Phylogenetic reconstruction of 31 distinct haplotypes based on a combined analysis of two mitochondrial gene

Do Marine Mammals Diversify More Slowly Than Non‐Marine Mammals?

Journal of Biogeography, Volume 53, Issue 1, January 2026.
ABSTRACT Aim Species richness is generally lower in marine than in terrestrial ecosystems, but the reasons behind this disparity remain unclear. This study examines whether marine mammals diversify at a slower pace than their non‐marine counterparts, aiming to shed light on the factors explaining potential diversification differences among them ...

Comparative Analysis of the Whistles of Three Oceanic Dolphins in the Comoros

Marine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT The Shisiwani National Park (Anjouan, Comoros) is a cetacean biodiversity hotspot. However, the vocal behavior of marine mammals inhabiting the area has never been studied. In 2023, we conducted a 400‐nautical‐mile survey from a 5‐m motorboat to determine their presence.

Melon‐Headed Whale (Peponocephala electra) Occurrence in the Equatorial Mid‐Atlantic Ocean With Descriptions of Their Whistles

Marine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT Acoustic studies for any cetacean species in tropical Atlantic Ocean waters are scarce, especially for oceanic dolphins, such as the melon‐headed whale, Peponocephala electra. Here we describe a unique visual and acoustic record for this species, filling an information gap about the acoustic patterns of these delphinids in this part of the ...

A Detailed Characterization of the Whistle Repertoire of Fraser's Dolphins (Lagenodelphis hosei) From the Lesser Antilles

Marine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT Fraser's dolphin (Lagenodelphis hosei) remains poorly studied due to its elusive behavior, rarity, and preference for deep offshore habitats. While dolphins use frequency‐modulated whistles for communication, detailed acoustic descriptions exist for only a few species.
