Benthic marine seaweeds are subjected to considerable hydrodynamic loads which may damage and dislodge them. Different forms of attachment systems assure that they remain in place, such as the attachment disc of the intertidal brown alga Fu...
No Effect in Plasma Corticosterone Levels After Observation of Diseased Conspecifics [0.03%]
观察患病同种个体对血浆皮质酮水平没有影响

Organisms commonly respond to stressors in their environment by increasing the secretion of corticosterone (CORT). While increased CORT is acknowledged as a response to predation risk by organisms inhabiting a landscape of fear, new researc...
Fusion of the Pharyngeal Wall to the Soft Palate Around the Laryngeal Inlet Isolates the Airway in Odontocete Cetaceans [0.03%]
齿鲸目的声门区域咽壁融合至软腭使气道隔离
A W Vogl,R Cieri,P Palia et al.
A W Vogl et al.
In odontocete cetaceans (toothed whales, dolphins, and porpoises), a palatopharyngeal sphincter permanently anchors the laryngeal inlet in the nasopharynx and isolates the airway from the gut tube. Using an MRI data set of a pacific white-s...
Population- and Species-Level Variation in Near- and Mid-infrared Radiation in Birds: A Preliminary Analysis [0.03%]
鸟类近红外和中红外辐射的个体、种群及物种水平变异的初步分析
T Lee,M Barrett,L Pilon et al.
T Lee et al.
Animal coloration has diverse functions, such as camouflage, communication, thermoregulation, and protection from UV damage and more, and can be shaped by environmental selective pressures. Some climatic selective pressures are strong enoug...
Unsupervised Wing-Bone Morphogroups in Bats Reveal Phylogenetic and Functional Patterns [0.03%]
无监督的蝙蝠翅膀骨骼形态分类揭示了其亲缘和功能模式
S S Zalapa,J M Vargas-Aldaco,S Guerrero-Vázquez et al.
S S Zalapa et al.
Bat wings are complex biomechanical systems whose skeletal components play a central role in shaping flight performance. Although wing morphology in bats has traditionally been characterized using aerodynamic indices and ecological guilds, ...
Shifting Perceptions about Microbes and Scientists: Reflections on Activities with High School Students [0.03%]
对高中生开展活动引发的关于微生物及科研工作者的一些看法变迁的思考
E Funk,A Lasek,K A Schmidtke et al.
E Funk et al.
Engaging students in science influences not only their knowledge but also their interest in becoming part of a scientific community. Where people hold negatively stereotyped views, they are unlikely to appreciate communications of nuanced f...
