Humans are not unique: difficult birth is common in placental mammals
Biological Reviews, Volume 101, Issue 5, Page 2214-2239, October 2026.ABSTRACT Human childbirth is widely presumed to be uniquely difficult and dangerous compared to birth in other mammals. Tight fetopelvic proportions can result in obstructed labour and contribute to high rates of maternal and neonatal mortality. Ideas summarised under the ‘obstetrical dilemma’ have contributed to this assumption by explaining difficult

Marine Mammal Science, Volume 42, Issue 4, October 2026.ABSTRACT In this study, we investigated alliance formation and complexity in male Indo‐Pacific bottlenose dolphins around Mikura Island using 5 years of data collected through underwater observations. Focusing on 18 mature males, we examined affiliative behaviors (proximity and rubbing), consortships, and associations. First, we tested the relationship

Journal of Anatomy, Volume 249, Issue 3, Page 587-603, September 2026.This study investigated how variations in the shape of the astragalus affect tarsal joint behavior, using CT scans. In artiodactyls with a double‐pulley astragalus, the calcaneus shifted plantarly during plantarflexion. This suggests the movement increases hindlimb functional length and contributes to enhanced running speed.

Beyond branch lengths: A fuzzy theory of evolutionary distinctiveness
Ecosphere, Volume 17, Issue 8, August 2026.Abstract In the face of accelerating biodiversity loss, conservation strategies require effective tools to identify species of high conservation priority. In this context, the index of evolutionary distinctiveness (ED), which quantifies the unique contribution of individual species to the overall phylogenetic diversity of a given assemblage, has played

The first description of Setaria tundra (Issaitshikoff & Rajewskaya, 1928) in roe deer from Croatia
Helminthologia, 2019 Genus Setaria, Viborg 1795, comprises 46 species that parasitize in the peritoneal cavity of Artiodactyla, Perissodactyla and Hyracoidea. The majority of these infections pass unnoticed, but occasionally they can induce severe peritonitis or neurological
