Morphological variation in atlas and axis of Neotropical spiny rats (Rodentia, Echimyidae)
The Anatomical Record, EarlyView.Abstract The unique morphologies of the first two cervical vertebrae, the atlas and axis, represent a significant innovation in mammalian evolution. These structures support the weight of the head and enable intricate movements of the head and neck.

A suture in time: The ontogeny of cranial suture morphology in mammals
Journal of Anatomy, EarlyView.Mammal cranial sutures are important indicators of the biomechanical and developmental pressures acting upon the skull. Across three prominent sutures dividing the vault of the mammalian skull, divergent patterns emerge both taxonomically and developmentally.

Palaeoecology of Oligo-Miocene macropodoids determined from craniodental and calcaneal data [PDF]
, 2016 Analyses of craniodental and calcaneal material of extant macropodoids show that both dietary and locomotor types are statistically distinguishable. Application of the craniodental data to fossil macropodoids from the Oligo-Miocene of South Australia ...

The FASEB Journal, Volume 39, Issue 23, 15 December 2025.Hibernating mammals preserve satellite cell viability during extreme cold exposure by suppressing ferroptosis through elevated GPX4 expression. Although these cells survive cold stress, myogenic activation and differentiation are markedly reduced, leading to delayed muscle regeneration in vivo.

Species Richness Gradients Vary Across Phylogenetic Scales
Global Ecology and Biogeography, Volume 34, Issue 12, December 2025.ABSTRACT Aim To determine how species richness gradients—commonly considered universal—vary across the phylogenetic hierarchy of birds and mammals, and to uncover how clade age and size predetermine the gradients. Location Global. Time Period Last 120 million years. Taxa Studied Birds and mammals (~15,000 species).
