Life History and Reproductive Parameters in an Increasingly Abundant Killer Whale Population

Ecology and Evolution, Volume 16, Issue 8, August 2026.
In the coastal waters of the eastern North Pacific, multiple discrete populations of killer whales exhibit distinct patterns in demography and abundance that are partially captured by population vital rates. We used 50 years of photographic identification data to estimate parameters relevant to maturation, fecundity, and mortality for a unique ...

Social information about others' affective states in a human‐altered world

Journal of Animal Ecology, Volume 95, Issue 8, Page 1311-1325, August 2026.
Faced with anthropogenic change, animals now encounter challenges different from their evolutionary past. To cope with such challenges, animals may use social information about others' affective states to guide their decisions. Considering affective states of wild animals could have important implications for animal welfare and wildlife conservation ...

An experimental approach to assess the combined effects of multiple stressors on a large vertebrate species

Conservation Biology, Volume 40, Issue 4, August 2026.
Abstract The design of experiments to investigate the combined effects of multiple stressors requires exposing target organisms to multiple combinations of stressor doses. Concurrent manipulation of stressors is often infeasible with wildlife, but long‐lasting health effects allow individual health to be used as an integrator of prior stressor exposure.

A contribution to the anatomy of two rare cetacean species: The hourglass dolphin (Cephalorhynchus cruciger) and the spectacled porpoise (Phocoena dioptrica)

The Anatomical Record, Volume 309, Issue 7, Page 1797-1820, July 2026.
Abstract The anatomical description of the hourglass dolphin (Cephalorhynchus cruciger) and the spectacled porpoise (Phocoena dioptrica) remains largely unexplored, due to limited specimen availability and preservation challenges. This study employed digital imaging techniques, conventional histology, and computed tomography to provide visualization of

The Case Study of Nesfatin-1 in the Pancreas of Tursiops truncatus

Frontiers in Physiology, 2018
Nesfatin-1 (Nesf-1) is an anorexigenic peptide involved in the regulation of homeostatic feeding. Nesf-1 is expressed in the central nervous system and other organs, including pancreas, where it promotes the release of insulin from β-cells. This raises the possibility that Nesf-1 dysfunction could be involved in metabolic disorders, particularly in ...

Nursing Behavior of Bottlenose Dolphin (Tursiops truncatus) Calves from 1990-2014 at Brookfield Zoo Chicago, USA [PDF]

Animal Behavior and Cognition
While the common bottlenose dolphin (Tursiops truncatus) population under managed care in North American zoos and aquariums is self-sustaining, understanding normal nursing behavior can help management make informed care decisions for neonates and future

Social object play between captive bottlenose and Risso's dolphins.

PLoS ONE, 2018
Many animal species engage in social object play with movable objects. Two bottlenose dolphins (Tursiops truncatus) and one Risso's dolphin (Grampus griseus) owned by the Kujukushima Aquarium, Japan, occasionally shared and played with an object. Herein,
