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 ...

Another polymorphic mitochondrial genome of Grampus griseus and phylogeny of family Delphinidae

Mitochondrial DNA. Part B. Resources, 2021
Risso’s dolphin (Grampus griseus Cuvier, 1812) is the only species of genus Grampus and a cosmopolitan marine inhabitant. Here, we report a polymorphic complete mitochondrial genome of G. griseus.

Multi-locus phylogeny of dolphins in the subfamily Lissodelphininae: character synergy improves phylogenetic resolution [PDF]

, 2006
Background Dolphins of the genus Lagenorhynchus are anti-tropically distributed in temperate to cool waters. Phylogenetic analyses of cytochrome b sequences have suggested that the genus is polyphyletic; however, many relationships were poorly resolved ...

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.

How to define a dolphin “group”? Need for consistency and justification based on objective criteria

Ecology and Evolution, 2022
Group living is a critical component of the ecology of social animals such as delphinids. In many studies on these animals, groups represent sampling units that form the basis of the collection and analysis of data on their abundance, behavior, and ...

Historical Biogeography of Delphininae Dolphins and Related Taxa (Artiodactyla: Delphinidae) [PDF]

Journal of Mammalian Evolution, 2016
Delphinine dolphins arose via a recent, rapid radiation, probably within the last four million years. Although molecular phylogenies are increasingly well resolved, patterns of morphology-ecology-geography are hard to link to phylogeny or to translate into taxonomy.

Ethnoecology of small cetaceans: interactions between an artisanal fishery and dolphins in northern Rio de Janeiro, Brazil [PDF]

Biotemas, 2012
Studies in northern Rio de Janeiro indicate there are interactions between fisheries and cetaceans, but there are no studies that focus on the knowledge fishermen have about these animals.

Differences in the whistle characteristics and repertoire of Bottlenose and Spinner Dolphins

Anais da Academia Brasileira de Ciências, 2004
Several methods have been used to compare the whistles produced by dolphins. The two methods used in this study are: (1) a classification of whistle contours in six categories (i.e.

First Comprehensive Study of Telomere Length Measured by Southern Blot Hybridization and Oxidative Stress Across 12 Captive Marine Mammal Species

Marine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT Telomeres, repetitive nucleotide sequences at chromosome ends, shorten with oxidative damage and cell replication, and are increasingly used as biomarkers of stress and physiological state. Despite this potential, telomere length (TL) in marine mammals has been measured using Southern blot hybridization in only a few cases, often from ...
