Hibernation is an elaborate response strategy employed by numerous mammals to survive in cold conditions that involves active suppression of metabolism. Despite the role of mitochondria as energy metabolism centers during hibernation, the adaptive and evolutionary mechanisms of mitochondrial genes in hibernating animals, like hedgehogs in eulipotyphlan species, are not yet fully understood. In this study, we sequenced and assembled mitochondrial genomes of the hibernating four-toed hedgehog () and the non-hibernating Asian house shrew ().

The seed microbiota, a still underexplored component of plant-microbe interactions, plays a pivotal role in plant development and holds significant promise for advancing sustainable agriculture. By influencing essential processes such as germination, stress tolerance, nutrient acquisition and defence, seed-associated microbes offer unique advantages beyond those of soil- or rhizosphere-associated microbiomes. Notably, they are transmitted both vertically and horizontally; however, fundamental questions remain regarding their origin, ecological dynamics and functional roles across environments.

G-quadruplexes (G4) are four-stranded nucleic acid structures formed within sequences containing repeated guanine tracts separated by intervening loop regions. Abundant in the human genome, they play crucial roles in transcription regulation and genome maintenance. Although theoretically capable to adopt 26 different folding topologies─primarily differing in loop arrangements─only 14 of these have been observed experimentally.

Migration is widespread among animals but varies in its manifestation with differences in direction, distance and obligatory nature. Understanding the evolution of migration requires insight into not only the development of this behaviour but also the loss of it. Partial migration, where some individuals within a population migrate while others stay, provides a unique opportunity to identify the proximate factors determining migratory/resident behaviours.

Symbiotic relationships shape the evolution of organisms. Fungi in the genus Escovopsis share an evolutionary history with the fungus-growing "attine" ant system and are only found in association with these social insects. Despite this close relationship, there are key aspects of Escovopsis evolution that remain poorly understood.
