Corpses as Repositories of Information and Funerals as Information Centres: Why Natural Selection Favours the Bereaved

open access: yesEthology, EarlyView.
Corpses are repositories of information about the cause of death. The distress of the bereaved acts as an honest signal drawing conspecifics to the body, enabling them to learn quickly about the death, adapt their behaviour, and spread knowledge of threats across multiple social levels.

Patterns of spinal motion, kinematic spaces and the land‐to‐sea transition in carnivorans

open access: yesThe Anatomical Record, Volume 309, Issue 11, Page 3257-3275, November 2026.
Using 3D reconstructions, we quantify intervertebral joint mobility to investigate how cervical, thoracic, and lumbar vertebral regions evolved distinct kinematic roles in pinnipeds. The findings reveal lineage‐specific adaptations for swimming and highlight the functional significance of vertebral joint flexibility in ecological transitions.

Habitat selection and refuge‐use by a color polymorphic salamander reveal behavioral niche differences

open access: yesEcology and Evolution
Color polymorphic species provide an excellent opportunity to investigate the ecology and evolution of intraspecific niche differences. The red‐backed salamander, Plethodon cinereus, is a fully terrestrial lungless salamander with two common color forms,

Can omnivores be considered keystone species? Bears as a study case

open access: yesEcosphere, Volume 17, Issue 11, November 2026.
Abstract The functional roles of herbivores and carnivores in ecosystems have been relatively well studied: both can shape ecosystems through strong direct and indirect top‐down controls on other guilds. By contrast, the role omnivores play has been rarely explored, even though their diet spans several trophic levels and potentially has numerous ...

Adaptive Immunity in Marsupials

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 345, Issue 9, Page 913-932, November 2026.
Comparison of the marsupial and eutherian adaptive immune systems. ABSTRACT Marsupials diverged from eutherian mammals 125–160 million years ago. Although evolutionarily distinct, both groups of mammals can produce complex adaptive immune responses to antigens with several key differences.

Fleas From the Northern Hairy‐Nosed Wombat and Other Mammalian Hosts of Australia

open access: yesAustral Entomology, Volume 65, Issue 4, November 2026.
ABSTRACT One of us (DKM) amassed a collection of 283 adult fleas (18 species) from donations by staff of the Queensland National Parks and Wildlife Service and other mammalogists, over 20 years (1967–87). Among this large collection were the first fleas to be found on three species of Australian mammals: (i) Lasiorhinus krefftii, the northern hairy ...
