Sloths exhibit specialized morphological and behavioral adaptations for crypsis, including slow movement and camouflaged pelage that reduces detection by predators. However, adult males of three three-fingered sloth species (Bradypus spp.) ...
Using laser-induced breakdown spectroscopy to explore the functional anatomy of skeletal appendages in migratory and resident birds [0.03%]
利用激光诱导击穿光谱技术探索迁徙鸟类和留鸟骨骼附肢的功能解剖学差异

Gehad M M Teryak et al.
Migration is the primary strategy employed by temperate birds to avoid experiencing harsh winter conditions. Consequently, the bones and wings of migratory birds have evolved distinctive morphological, structural, and microstructural charac...
Morphological conservatism and natural history in two sympatric Amerotyphlops species (Serpentes: Typhlopidae) from the Atlantic Forest of Northeastern Brazil [0.03%]
巴西东北部大西洋森林中两种共存的Amerotyphlops物种（蛇目：盲蛇科）的形态保守性和自然史
Anderson Kennedy Soares De-Lima,Paula Araújo,Gabriela Hirata et al.
Anderson Kennedy Soares De-Lima et al.
Blindsnakes (Scolecophidia) are among the most morphologically conservative reptiles, yet the extent and nature of their phenotypic variation is poorly documented. We provide an integrative assessment of allometry and trophic ecology in two...
Is developmental instability sex-specific? Case study in two spiny lizards with different reproductive modes [0.03%]
发育不稳定具有性别特异性吗？两种不同生殖模式刺 lizard 的案例研究

Aldo Gómez-Benitez et al.
Developmental instability reflects an organism's ability to buffer genetic and environmental perturbations during growth and is commonly assessed through fluctuating asymmetry and canalization. Evidence from diverse animal groups suggests t...
Diversity of tarsal attachment structures in Mantodea (Insecta) includes two distinct attachment pad micro-morphologies [0.03%]
螳䗛目昆虫后足附着结构的多样性包括两种独特的垫状微形态

Praying mantises (Mantodea) are well known for their predatory behavior and striking appearance, yet surprisingly little is known about their tarsal attachment systems. Comparative studies on other polyneopteran insect clades based on large...
Getting a grip on the squid hectocotylus: Sexually dimorphic glandular system underlies spermatophore transfer in Doryteuthis pleii (Blainville, 1823) [0.03%]
圈住乌贼的腕 arm：拟饰纹幼柔乌贼(Doryteuthis pleii)的雄性二态性腺系统及其精荚传递机制研究

During mating, male cephalopods generally use a modified arm (the hectocotylus) to transfer spermatophores to the female. To shed some light on the functional morphology of such an important organ in cephalopod reproduction, we have thoroug...
Histologic and immunohistochemical changes in amputated and scarring lizard limb of Scincella tsinlingensis [0.03%]
秦岭蝘蜓截肢和伤口愈合的组织学及免疫组化变化

Lizard tail regeneration and limb amputation provide contrasting amniote models for regenerative failure. A limb wound healing model was established in 48 Scincella tsinlingensis through standardized surgical amputation protocols, followed ...
Hydrodynamic flow in the peripheral olfactory system of pelagic fishes: A comparison between southern bluefin tuna, Thunnus maccoyii and black marlin, Istiompax indica [0.03%]
远洋鱼类外周嗅觉系统的水动力学流动机制比较：南部蓝鳍金枪鱼和黑 Marlins 的研究
Myoung-Hoon Ha,Travis Dutka,Julian Pepperell et al.
Myoung-Hoon Ha et al.
The peripheral olfactory system of teleosts reveals great morphological diversity, which directly affects the delivery of water-borne odorants in an aquatic environment. In pelagic teleosts, hydrodynamic conditions also play an important ro...

Reuven Yosef et al.
Egg size is a key determinant of reproductive success in birds, influencing nestling growth, survival, and overall fitness. For Lesser Kestrels Falco naumanni, a small raptor often supported by nest-box programs, we hypothesized that female...
