Body size evolution through shifting climatic conditions in Mesozoic dinosaurs
Palaeontology, Volume 69, Issue 3, 2026.Abstract Body size evolution is commonly associated with climate change. For example, birds and mammals have been found to decrease in size with anthropogenic global warming. Recent studies have inferred distinct shifts in climatic niche preferences among the three major dinosaur clades.

Genomic Insights Into Carnivorous Fish in the Characiformes
Ecology and Evolution, Volume 16, Issue 4, April 2026.This study employed comparative genomic approaches using 12 high‐quality Characiformes genomes (covering nine subfamilies) with zebrafish as an outgroup to explore the molecular mechanisms underlying the carnivorous adaptation of Characiformes. Expanded gene families, positively selected genes, and rapidly evolving genes in carnivorous species were ...

Acta Physiologica, Volume 242, Issue 4, April 2026.ABSTRACT Aim Unlike humans, brown bears (Ursus arctos) uniquely preserve skeletal muscle mass and function during months of hibernation despite prolonged fasting and inactivity. We investigated how mitochondrial energetics respond in skeletal muscle to support this remarkable resilience.

Boreas, Volume 55, Issue 2, Page 503-516, April 2026.Bears deviate from the inhibitory cascade model (ICM) during molar size evolution, with two significant deviations linked to changes in diet: Ursus minimus and Ursus deningeri. Many bears exhibit a ‘partial ICM’, highlighting the relationship between relative molar size, dietary adaptations and dental development across different species.
