Sociability Under Anthropogenic Change: From Individual Behaviour to Population‐Level Consequences

Ecology and Evolution, Volume 16, Issue 10, October 2026.
Our review synthesises empirical and theoretical research on how anthropogenic environmental change reshapes animal social behaviour from individuals to populations. We use sociability as an individual‐level lens, distinguishing context‐dependent expression from repeatable interindividual differences and linking both to social relationships, network ...

Dolphin Longevity and Long‐Term Site Fidelity in the Mississippi Sound: Insights From a 1982 Health Assessment

Ecology and Evolution, Volume 16, Issue 10, October 2026.
Current photo‐ID surveys have identified 10 common bottlenose dolphins that were originally freeze‐branded from a health assessment in the Mississippi Sound from 1982. These dolphins have experienced long‐term site fidelity with confirmed ages being above 30+ years old, and one individual being 47 years old.

Clicking in Shallow Rivers : Short-Range Echolocation of Irrawaddy and Ganges River Dolphins in a Shallow, Acoustically Complex Habitat [PDF]

, 2013
Toothed whales (Cetacea, odontoceti) use biosonar to navigate their environment and to find and catch prey. All studied toothed whale species have evolved highly directional, high-amplitude ultrasonic clicks suited for long-range echolocation of prey in ...

Ecology of Chilean dolphins and Peale's dolphins at Isla Chiloe, southern Chile [PDF]

, 2007
Information on the ecology of sympatric species provides important insights into how different animals interact with their environment, with each other, and how they differ in their susceptibility to threats to their survival.

Genomic Characterization of Aeromonas dhakensis Isolated From a Fatal Dolphin Case

Environmental Microbiology Reports, Volume 18, Issue 5, October 2026.
Comparative genomic analysis of an Aeromonas dhakensis isolate recovered from a fatal dolphin case revealed close relatedness to previously described strains and a broadly comparable virulence‐associated gene profile, including rtxA, with no isolate‐specific virulence‐associated annotations identified.

Population genetics of bottlenose dolphins (Tursiops truncatus) from an Anglo-Saxon archaeological site in comparison with modern populations. [PDF]

, 2004
Bottlenose dolphins {Tursiops truncatus) exhibit a cosmopolitan distribution, being found in temperate and tropical oceans throughout the world. Members of this species in the waters surrounding Britain are the most northerly populations and show a ...

Cool‐Water Dolphins Have Larger Appendages Than Warm‐Water Dolphins

Journal of Biogeography, Volume 53, Issue 10, October 2026.
ABSTRACT Aim Endothermic marine mammals face significant thermoregulatory challenges due to heat loss in the highly conductive marine environment. Allen's rule states that endothermic animals in cold environments have smaller appendages than those in warmer environments.

The encoding of individual identity in dolphin signature whistles : how much information is needed? [PDF]

, 2013
Bottlenose dolphins (Tursiops truncatus) produce many vocalisations, including whistles that are unique to the individual producing them. Such “signature whistles” play a role in individual recognition and maintaining group integrity.

Mitochondrial Variation of Bottlenose Dolphins (Tursiops truncatus) from the Canary Islands Suggests a Key Population for Conservation with High Connectivity within the North-East Atlantic Ocean

Animals
In recent decades, worldwide cetacean species have been protected, but they are still threatened. The bottlenose dolphin (Tursiops truncatus) is a vulnerable keystone species and a useful bioindicator of the health and balance of marine ecosystems in ...
