The Anatomical Record, Volume 309, Issue 2, Page 397-416, February 2026.Abstract Mysticetes, or baleen whales, have an air sac on the ventral surface of the larynx known as the “laryngeal sac.” The primary hypothesis regarding this structure's function is that it is involved in sound production. However, several other functions have been proposed, including air recycling, air storage, and even buoyancy control.

The Genetic and Morphological Basis of Local Adaptation to Elevational Extremes in an Alpine Finch
Ecology and Evolution, Volume 16, Issue 2, February 2026.We investigated morphological and genetic variation in the Sierra Nevada Gray‐crowned Rosy Finch to identify traits important for local adaptation in alpine environments. By combining trait measurements with genome‐wide analyses, we uncovered loci linked to thermoregulation, altitude adaptation, and cold tolerance.

Zoo Biology, Volume 45, Issue 1, Page 37-45, January/February 2026.Female budgerigars (Melopsittacus undulatus) did not significantly elevate their plasma corticosterone levels in response to human presence at the beginning of the experiment. However, plasma corticosterone was significantly elevated by restraint stress, the return of a neighbor that received restraint stress, and human presence at the end of the ...

Functional Ecology, Volume 40, Issue 2, Page 323-337, February 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Sexual conflict affects the amount and duration of offspring care each parent invests, resulting in multiple parental care strategies sometimes coexisting within a single population.

eLife, 2015 Innate pluripotency of mouse embryos transits from naive to primed state as the inner cell mass differentiates into epiblast. In vitro, their counterparts are embryonic (ESCs) and epiblast stem cells (EpiSCs), respectively.

Methods in Ecology and Evolution, Volume 17, Issue 2, Page 339-356, February 2026.Abstract Collection of large behavioural data‐sets on wild animals in natural habitats is vital in ecology and evolution studies. Recent progress in machine learning and computer vision, combined with inexpensive microcomputers, has unlocked a new frontier of fine‐scale markerless measurements.

Animal Conservation, Volume 29, Issue 1, Page 86-99, February 2026.Reproductive success rates are a key parameter determining the recovery potential of ex‐situ managed threatened species, with high rates often being required to produce offspring for wild releases while ensuring ex situ population viability. Here, we quantify reproductive success rates in the Extinct in the Wild sihek (Guam kingfisher) and find ...

Biological Reviews, Volume 101, Issue 1, Page 336-363, February 2026.ABSTRACT The ability of individuals to cope with their environment, and therefore the likelihood that they survive and pass on their genes (i.e. fitness), is largely determined by physiological state. Tracking physiological state in wild animals, however, is challenging.

BMC Genomics, 2009 Background The detection of odorants is mediated by olfactory receptors (ORs). ORs are G-protein coupled receptors that form a remarkably large protein superfamily in vertebrate genomes.

Biological Reviews, Volume 101, Issue 1, Page 419-436, February 2026.ABSTRACT Humans play key roles in shaping the structure and processes of ecosystems globally, especially in cities. This recognition has prompted a recent focus on understanding urban systems via interactions between human social systems and ecological and evolutionary processes.
