Non-signaling functions of coloration include thermoregulation (thermal melanism hypothesis), protection against ultraviolet radiation (photoprotection hypothesis), and concealment from predators (crypsis hypothesis). We investigated whethe...
Sparrowhawk imitation or convergent alarm signal? A new hypothesis for bubbling call of cuckoos with empirical testing [0.03%]
Sparrowhawk拟态还是趋同的警戒信号？一种新的杜鹃鸣叫假说及其实证检验
Huisheng Wang,Xiangyang Chen,Jiaojiao Wang et al.
Huisheng Wang et al.
Alarm calls in bird vocalizations serve as acoustic signals announcing danger. Owing to the convergent evolution of alarm calls, some bird species can benefit from eavesdropping on certain parameters of alarm calls of other species. Vocal m...
Reproductive behavior and early immature morphology of Portschinskia magnifica: implications for evolutionary biology in bot flies (Diptera: Oestridae) [0.03%]
Portschinskia magnifica的繁殖行为和幼虫早期形态：在食肉蝇科进化生物学中的意义
Xinyu Li,Wentian Xu,Yaqian Fan et al.
Xinyu Li et al.
Portschinskia Semenov is a rare genus of bot flies whose larvae are obligate parasites of pikas and murine rodents, crucial for understanding the evolutionary biology of Oestridae. However, limited information on their adult biology and ear...

The brood-parasitic brown-headed cowbird (Molothrus ater) has one of the shortest incubation periods of any bird. Brown-headed cowbird eggs, and those of other avian brood parasites, tend to be more spherical due to their greater relative w...
Bacterial microbiome and their assembly processing in two sympatric desert rodents (Dipus sagitta and Meriones meridianus) from different geographic sources [0.03%]
两种不同地理来源的共域分布沙漠啮齿动物(Dipus sagitta和Meriones meridianus)及其细菌菌群组装过程的研究

The microbiome of mammals has profound effects on host fitness, but the process, which drives the assembly and shift of mammalian microbiome remains poorly understood. To explore the patterns of small mammal microbial communities across hos...
Costly calling: Marmots who alarm call at higher rates are less likely to survive the summer and live shorter lives [0.03%]
代价高昂的警告叫声：高频率发出警告叫声的花鼠更有可能在夏季存活下来，并且拥有更短的生命长度

Emitting alarm calls may be costly, but few studies have asked whether calling increases a caller's risk of predation and survival. Since observing animals calling and being killed is relatively rare, we capitalized on over 24,000 h of obse...
Call variation and calling site preference of three sympatric Boulenophrys frogs [0.03%]
三种同域分布的肩角蛙的变异呼叫及鸣叫位点偏好

Animals living in syntopy share acoustic space. Asian horned frogs are well known for their sympatric distribution, but little is known about their strategies to avoid acoustic niche competition. This study focused on three sympatric Boulen...

Climate change and its resulting effects on seasonality are known to alter a variety of animal behaviors including those related to foraging, phenology, and migration. Although many studies focus on the impacts of phenological changes on ph...
Tracking toads from dusk till dawn: linking inter- and intra-individual variation in movement behavior [0.03%]
从黄昏到黎明的蟾蜍追踪：连接运动行为的个体间和个体内变异
Nathalie Jreidini,David M Green

Animals can differ in their individual movement behaviors during their daily displacements. Studies of animal movement patterns often disregard the need to understand individual variation in these patterns and the role of this variation in ...
Long-term effect of inbreeding in the yellow steppe lemming, Eolagurus luteus, captive colony [0.03%]

In the current research, we investigated the impact of gradually increasing inbreeding on the life span and reproductive rate of yellow steppe lemmings, Eolagurus luteus, that reproduced in the Moscow Zoo. The focal captive colony existed f...
