High altitudes are challenging for the animals that inhabit these environments. The Xizang plateau frog (Nanorana parkeri) survives in high‐altitude environments through a synergistic strategy of metabolic remodeling and protein expression adjustment to optimize energy efficiency and enhance cellular protection.

Integrating comparative spectrometry, image analysis, and thermal modeling, we reveal that (1) females optimize crypsis via background matching, (2) males prioritize high‐contrast disruptive patterning at a significant thermoregulatory cost (reduced solar heat gain), and (3) habitat‐specific monomorphism in Diploderma slowinskii underscores ecological ...

We decode mitochondrial genomes across all extant canids, revealing lineage‐specific codon optimization driven by altitude, predation, and body size. A tripartite framework integrates geological events, metabolic constraints, and adaptive radiation to explain carnivore evolution.

The relationship between the position of a flea species in the networks and its functional originality was found to be consistently positive in all realms, independently of which originality index was used. ABSTRACT We investigated the relationships between a species’ network position (measured as the combined normalized degree, species strength, and ...

We investigated how three rodent species respond to the seasonal availability of Araucaria angustifolia seeds. While Oligoryzomys spp. increased seed consumption and abundance during seed production, the more insectivorous Akodon paranaensis maintained a broader diet.

Female‐Biased Sexual Size Dimorphism and Its Potential Causes in Hairy‐Winged Bats
Based on the integration of molecular genetics, traditional and geometric morphology, and acoustic characteristics of hairy‐winged bats (a species that was historically misclassified into two species due to extreme craniodental divergence between the sexes) in multiple regions of China, we quantified the sexual size dimorphism (SSD) between males and ...

Volatile Compounds in Feathers of the Scarlet Macaw (Ara macao) Reflect Sex and Pair‐Bond Status
Scarlet macaws exhibit sex‐ and pair‐related differences in plumage volatile composition, with males showing greater chemical richness. Partnered individuals differ in specific compound classes, whereas no clear association with immune function was detected. These results support a potential role for olfactory cues in sexual and social communication in
