How wildlife respond to tropical cyclones: short‐term tactics and long‐term impacts
ABSTRACT From butterflies to lizards and from sharks to seabirds, wildlife exhibit tactics to survive the impacts of tropical cyclones, also known as hurricanes, cyclones, or typhoons depending on where they occur. Some species seek refuge during the storm by moving, some remain in place and ride it out, and others move longer distances, avoiding the ...

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

Maternal and alloparental disciplinary behavior were examined in a community of Atlantic spotted dolphins (Stenella frontalis) on Little Bahama Bank, Bahamas. An operational definition of discipline was created and analyses were performed of underwater behavior by spotted dolphins.

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.

Conservation ecology and phylogenetics of the Indus River dolphin (Platanista gangetica minor) [PDF]
The historical range of the Indus River dolphin has declined by 80% since the 19th century and has been fragmented into 17 river sections by construction of irrigation barrages.

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

ABSTRACT Two coastal dolphin species, the common bottlenose dolphin (Tursiops truncatus—Tt) and the short‐beaked common dolphin (Delphinus delphis—Dd), co‐occur along the southern Israeli Mediterranean coast, where the critically endangered Dd population faces ecological pressures, potentially including competitive exclusion by that of the Tt ...

Using Aerial Photogrammetry to Estimate Body Condition and Assess Sexual Dimorphism in Narwhals
ABSTRACT The Arctic is warming rapidly, impacting ice‐dependent species and communities that rely on them for resources. Body condition indices (BCI) are widely used to assess individual health within populations. We adapted the methodology to improve accessibility for estimating narwhal body condition from drone footage, using body length, body width,
