Bird feathers serve numerous essential functions, with water repellency being particularly critical, as many other feather functions depend on remaining dry. Despite its importance, significant gaps remain in our understanding of the mechan...
Body mass of streaked shearwaters affects wingbeat during ascending and sea-surface flight [0.03%]

Streaked shearwaters (Calonectris leucomelas) return to their breeding colonies, which are established in elevated locations on islands, by increasing their flight altitude immediately before landing. We quantitatively analysed the characte...
Pollen release during buzz pollination depends on vibration amplitude and floral vibration transmission, but not on spectral composition [0.03%]
花粉释放依赖于振幅和花朵振动传导，而不是频谱组成

Bees use vibrations across behavioural contexts, including a specialised foraging routine in which they vibrate flowers to release pollen (floral vibrations). Floral vibrations often have complex spectral properties, combining fundamental f...
Continuous sampling of cerebrospinal fluid from the 3rd ventricle of the hypothalamus to identify accumulating or depleting metabolites during hibernation [0.03%]
连续采集下丘脑第三脑室脑脊液以鉴定冬眠期间积累或消耗的代谢物

Hibernation is a seasonally regulated process dramatically reducing metabolic rate and subsequently core body temperature (Tb). Many hibernators repeatedly cycle between torpor and arousal (T-A cycling) throughout the hibernation season. Ho...
Seasonal variation in resting metabolic rate, thyroid hormones, and cortisol in the bottlenose dolphin (Tursiops truncatus) [0.03%]

Seasonal changes in metabolic rate have been studied to varying degrees in terrestrial mammals, but relatively little is known about this phenomenon in odontocetes. Seasonal changes in thyroid hormone levels in bottlenose dolphins suggest p...

Animals time durations between arbitrary events to make predictions about their environment. This ability, known as interval timing, has been studied in the context of reward expectancy in the laboratory and foraging in the wild. However, t...
Maternal swimming exercise training improves survival and the heritability of thermal tolerance and length in brown trout offspring [0.03%]

Hatchery-reared fish released to sustain wild populations exhibit low survival in the wild. Possible reasons are rearing conditions that preclude fish from displaying their natural swimming behaviour, which negatively affect their cardiores...

We report on recent methodological advances at the Life Science X-ray Scattering (LiX) beamline of the National Synchrotron Light Source II (NSLS-II) to support small-angle X-ray scattering experiments on straited muscles. These experiments...

For ectotherms such as insects, which have high surface area-to-volume ratios and are dependent upon environmental temperatures, physiological traits and/or a combination of behavioral mechanisms allow them to temporarily avoid sub-optimal ...
Salinity-induced metabolic reorganization in a long-lived marine osmoconformer Arctica islandica: Insights from contrasting arctic environments [0.03%]

Environmental salinity strongly shapes the physiology of osmoconforming marine invertebrates, yet population-level metabolic responses remain poorly understood. The ocean quahog Arctica islandica exhibits extreme geographic variation in gro...
