Evolutionary trade-off between innate and acquired immune defences in birds [0.03%]
鸟类先天免疫和获得性免疫防御的进化权衡
Piotr Minias,Wei-Xuan V-H Peng,Kevin D Matson
Piotr Minias
Background: The development, maintenance, and use of immune defences are costly. Therefore, animals face trade-offs in terms of resource allocation within their immune system and between their immune system and other phys...
Support for a radiation of free-living flatworms in the African Great Lakes region and the description of five new Macrostomum species [0.03%]
非洲大湖地区的自由生活扁虫辐射支持以及五种新Macrostomum物种的描述

Jeremias N Brand
Background: The African Great Lakes have long been recognized as an excellent location to study speciation. Most famously, cichlid fishes have radiated in Lake Tanganyika and subsequently spread into Lake Malawi and Lake ...
Food patch use of Japanese quail (Coturnix japonica) varies with personality traits [0.03%]
鸡科动物日本鹌鹑的性格特征影响其觅食行为
Chunlin Li,Xinyu Zhang,Lin Cheng et al.
Chunlin Li et al.
Background: The classic optimal foraging theory (OFT) predicts animals' food patch use assuming that individuals in a population use the same strategy while foraging. However, due to the existence of animal personality, i...
Minimal resin embedding of SBF-SEM samples reduces charging and facilitates finding a surface-linked region of interest [0.03%]
.minimum树脂包埋可减少扫描透射电子断层重建样品的荷电效应并便于找到感兴趣的表面连接区域

Barbora Konopová
Background: For decoding the mechanism of how cells and organs function information on their ultrastructure is essential. High-resolution 3D imaging has revolutionized morphology. Serial block face scanning electron micro...
Third-party intervention and post-conflict behaviour in agonistic encounters of pigs (Sus scrofa) [0.03%]
第三方介入与猪冲突后的行为研究
Nicole Maffezzini,Simon P Turner,J Elizabeth Bolhuis et al.
Nicole Maffezzini et al.
Background: Third-party interference in agonistic contests entails a deliberate intervention in an ongoing fight by a bystanding individual (third party) and may be followed by post-conflict social behaviour to provide su...
Body mass is associated with hibernation length, body temperature, and heart rate in free-ranging brown bears [0.03%]
体重与荒野棕熊的冬眠时长、体温及心率有关
Alina L Evans,Boris Fuchs,Navinder J Singh et al.
Alina L Evans et al.
Background: Despite centuries of research, debate remains on the scaling of metabolic rate to mass especially for intraspecific cases. The high variation of body mass within brown bears presents a unique opportunity to st...

Various chalcidoid wasps can actively steer their terebra (= ovipositor shaft) in diverse directions, despite the lack of terebral intrinsic musculature. To investigate the mechanisms of these bending and rotational movements, we combined m...
Age-related mating rates among ecologically distinct lineages of bedbugs, Cimex lectularius [0.03%]
环境条件不同的臭虫(Cimex lectularius)谱系间的年龄和繁殖率关系
Tomáš Bartonička,Jana Křemenová,Ondřej Balvín et al.
Tomáš Bartonička et al.
Understanding how many mates an animal has in its lifetime is a critical factor in sexual selection. At the same time, differences in an organism's ecology, such as the quantity and quality of food, could be reflected in different mating ra...
Effects of meteorological conditions on brood care in cooperatively breeding carrion crow and consequences on reproductive success [0.03%]
气象条件对共同繁殖的乌鸦群体抚育的影响及其对繁殖成功的影响
Eva Trapote,Daniela Canestrari,Vittorio Baglione
Eva Trapote
Meteorological stressors (e.g., temperature and rain shortage) constrain brood provisioning in some bird species, but the consequences on reproductive success have been rarely quantified. Here we show, in a cooperatively breeding population...
Variations in small-scale movements of, Rousettus aegyptiacus, a Marburg virus reservoir across a seasonal gradient [0.03%]
不同季节埃及鼠耳蝠(马堡病毒贮主)小范围活动模式的差异性研究
Matthew R Wood,J Low de Vries,Jonathan H Epstein et al.
Matthew R Wood et al.
Background: Bats are increasingly being recognized as important hosts for viruses, some of which are zoonotic and carry the potential for spillover within human and livestock populations. Biosurveillance studies focused o...
