Investigating the Predation Risk of Coastal Dolphins via the Presence of Shark Bite Scars Across Southeast Queensland, Australia

Ecology and Evolution, Volume 16, Issue 6, June 2026.
Shark bite scars were analysed on coastal dolphins in southeast Queensland, Australia to compare the predation risk between species and habitats. Australian humpback dolphins (Sousa sahulensis) exhibited the highest bite rates and individuals found in sheltered waters had higher shark bite scar prevalence than open waters.

The Evolution of Masturbation in Birds

Ecology and Evolution, Volume 16, Issue 6, June 2026.
Masturbation has been sporadically documented across animal groups, yet the evolutionary origins and persistence of this sexual behaviour are largely unexplored. Through combining targeted surveys with published accounts, we test hypotheses about why masturbation occurs using a phylogenetically broad dataset on the presence or absence of masturbation ...

Synchronous and Rhythmic Vocalizations and Correlated Underwater Behavior of Free-ranging Atlantic Spotted Dolphins (Stenella frontalis) and Bottlenose Dolphins (Tursiops truncatus) in the Bahamas

, 2015
Since 1985 a resident community of Atlantic spotted dolphins (Stenella frontalis), and bottlenose dolphins (Tursiops truncatus), have been studied underwater in the Bahamas.

Mating Attempts and Sustained Interest Behaviors of Wild Boars (Sus scrofa) Toward a Dead Conspecific

Ecology and Evolution, Volume 16, Issue 6, June 2026.
We documented behavioral responses of wild boars (Sus scrofa) to a conspecific carcass using camera traps throughout the full decomposition process. One adult male exhibited necrophilic behavior and sustained non‐feeding interactions with the carcass, highlighting pronounced individual variation.

The Cognitive Foundations of Teaching

Evolutionary Anthropology: Issues, News, and Reviews, Volume 35, Issue 2, June 2026.
ABSTRACT The propensity to teach is vital to human cultural evolution and to our ecological dominance of the planet, but its cognitive foundations remain poorly understood. Traditional explanations argue that teaching hinges on particular cognitive pre‐requisites, such as Theory of Mind.

Death Associated to Methicillin Resistant Staphylococcus aureus ST8 Infection in Two Dolphins Maintained Under Human Care, Italy

Frontiers in Immunology, 2018
The present study describes the isolation of Methicillin-resistant Staphylococcus aureus (MRSA) from respiratory tract of 2 dolphins of different origin, a stranded juvenile Risso's dolphin (Grampus griseus) and a captive born common bottlenose dolphin ...

Temporal changes in the dietary niche of sympatric seals provides insight into the role of competition in population declines

Oikos, Volume 2026, Issue 6, June 2026.
Competition theory suggests that interspecific prey competition can result in changes to the dietary niche, but obtaining timeseries of data from sympatric species experiencing temporal variation in competition is challenging. Scotland is an important area for two species of seals, but over the past 20 years, populations of harbour seals Phoca vitulina

Whole‐Genome‐Sequencing Reveals Demographic History and Patterns of Parallel Adaptive Evolution in Indo‐Pacific Bottlenose Dolphins (Tursiops aduncus) Across Coastal Australian Seascapes

Molecular Ecology, Volume 35, Issue 11, June 2026.
ABSTRACT Understanding how demographic dynamics interact with environmental heterogeneity is central to explaining patterns of genomic variation in the marine realm. Indo‐Pacific bottlenose dolphins (Tursiops aduncus) occur along most of the Australian coastline, from tropical to temperate waters, encompassing pronounced differences in temperature ...

High genetic structure and low mitochondrial diversity in bottlenose dolphins of the Archipelago of Bocas del Toro, Panama: A population at risk?

PLoS ONE, 2017
The current conservation status of the bottlenose dolphin (Tursiops truncatus) under the IUCN is 'least concern'. However, in the Caribbean, small and localized populations of the 'inshore form' may be at higher risk of extinction than the 'worldwide ...

Genomic Insights Into the Evolutionary History of Berardius Beaked Whales: Speciation Driven by Resource Specialization, Gigantism and Thermal Barriers?

Molecular Ecology, Volume 35, Issue 12, June 2026.
ABSTRACT Understanding the diversity of our oceans is fundamental now more than ever as climate change and human activities put increasing pressure on marine species and ecosystems. Beaked whales (family Ziphiidae) are among the most poorly understood marine mammals, in part due to their affinity to offshore underwater canyons and prolonged diving ...
