Robust but transient thermoregulatory responses to an acute thermal challenge in a free-living altricial songbird [0.03%]
自由生活的早成鸟对急性热刺激的稳健但短暂的体温调节反应

Elizabeth P Derryberry et al.
High temperatures are becoming the new normal as heat waves increase in frequency, intensity, and duration. Experimental evidence shows that acute heat triggers thermoregulatory mechanisms in songbirds, yet the persistence of these thermore...
Hormonal Influences on Sexual Dichromatism Across the Avian Tree of Life: A Primer [0.03%]
激素对鸟类生命之树两性差异的影响：入门指南

Color differences between the sexes (dichromatism) in birds are a hallmark example of a secondary sexual character that is frequently associated with sexual signaling and mate choice. Previous work has shown that the physiological and genet...
Introducing a Stay, Shift, Go framework for behavioral responses to wildfire smoke: American robin (Turdus migratorius) locomotory behavior changes as particle pollution intensifies [0.03%]
提出一种应对野火烟雾行为反应的“留、移、走”框架：当颗粒物污染加剧时，美洲红雀（Turdus migratorius）的移动行为会发生变化

J M Cornelius et al.
Wildfire smoke is an increasing disturbance across much of the globe that has received little attention as a selective force in animal behavior. Animals may have evolved behavioral strategies to cope with smoke exposure, but what those stra...

Genital spines are present in many groups of animals, including insects, squamates, fish and mammals, and their diverse functions have been established in some species. However, we have yet to characterize the morphology of genital spines i...
Intraspecific Trait Variation in the Mammalian Gastrointestinal Tract: A Digestive Dive and Systematic Literature Review [0.03%]
哺乳动物消化道性状的个体变异：一项系统文献综述及探讨

The gastrointestinal tract (GIT) represents the functional link between food and energy for organisms. It also harbors the gut microbiome, protects against toxins, and eliminates waste, all of which mediate individual health and fitness. Th...

In this work, we describe the development and application of a low-cost fluid interface visualizer referred to as the "Meniscope." The device works using a color-based surface gradient detector method that maps the gradient of an air-water ...
A dozen years of baleen hormones: Validations, discoveries, surprises, and next steps [0.03%]
鲸须素的十二年：认证、发现、惊喜与下一步

Since the first publication in 2014 reporting that progesterone is detectable in whale baleen, numerous studies have confirmed that patterns of hormones in baleen can provide a multi-year time series of continuous endocrine information from...
Modeling the functional capabilities of the bat wing hair sensor network: effective sensor distributions from optimal sensing [0.03%]
蝙蝠翅膀毛发传感器网络的功能建模：从最佳感应中获得有效的传感器分布

Effective control of flapping flight can benefit from rapid feedback about wing deformation and aerodynamic loading, yet the functional role of wing-embedded mechanosensors remains poorly understood. In bats, dense arrays of sensory hairs s...
Dynamic Morphospaces for Animal Locomotion: A Case Study in Bird Flight [0.03%]
动物运动的动态形态空间：鸟类飞行的案例研究
Lydia A France,Christina Harvey,Graham K Taylor
Lydia A France
Morphospaces represent the range of possible biological designs by placing different shapes into a common geometric space. They have revealed that high-dimensional morphological diversity in biological systems tends to concentrate along a r...
Functional morphology of passive prickle puncture varies between life-stages in Rubus allegheniensis [0.03%]
丛枝刺在不同生长阶段的Rubus allegheniensis中的功能形态学差异研究
J Martinez Paz,S B Crofts
J Martinez Paz
Blackberries, like many members of the genus Rubus, have prickles that provide puncture-based protection from herbivory. Our goal was to understand the mechanics of passive prickle puncture, and to discern if the functional morphology of pr...
