The evolution of alkaloid sequestration and modification in poison frogs provides an opportunity to explore the emergence of complex traits, particularly the importance of intermediate phenotypes. The origin of alkaloids in lineages of frog...
Characterizing the informativeness of pathogen genome sequence datasets about transmission between population groups [0.03%]

Cécile Tran-Kiem et al.
Pathogen genome analysis helps characterize transmission between population groups. The information carried by pathogen sequences comes from the accumulation of mutations within their genomes; thus, the pace at which mutations accumulate sh...

Speakers in conversation reuse each other's words, structures, meanings, sounds and gestures. This phenomenon-known as conversational alignment-is regarded as a cornerstone of successful communication and has garnered attention from researc...
Spatio-temporal spread of COVID-19 over three variant waves in the continental United States [0.03%]
美国本土三种新冠病毒变异株流行期间的时空传播规律分析

Viviane Callier
Understanding the spatio-temporal spread of infectious diseases is important to improve control, yet most studies lack granular epidemiological data and are complicated by heterogeneities in pre-existing immunity. The COVID-19 pandemic prov...
Evidence for chronotypes and associations with fitness-related traits in a wild insect [0.03%]
证据显示甲虫类型与野生物种的健身特征相关联

Ruonan Li
Consistent among-individual differences in the timing of daily activities are referred to as chronotype. While chronotype has been well studied in humans and some laboratory animals, field-based research remains scarce, particularly in inse...
Statistically significant chuckles: who is using humour at scientific conferences? [0.03%]
统计意义上的笑声：哪些人在科学会议上使用幽默？
Stefano Mammola,Diego Fontaneto,Andrea Santangeli et al.
Stefano Mammola et al.
We've all been there: 11.47, swamped by a long stretch of dense scientific talks at a conference. Six slides into a hyper-technical presentation, the speaker suddenly cracks a joke. The room erupts. Shoulders relax. Minds re-engage. Humour ...
Female reproductive investment is associated with male-biased adult sex ratios in a wild lemur population [0.03%]
在一个野外环尾狐猴种群中，雌性繁殖投资与雄性偏态成年性别比相关
Leonie Pethig,Claudia Fichtel,Peter M Kappeler
Leonie Pethig
Variation in adult sex ratios (ASR) offers important insights into evolutionary and ecological dynamics, as it reflects demographic processes and predicts sex-specific reproductive strategies. In most mammals, ASRs tend to be female-biased ...
Evidence for latitude-driven changes in diel rhythms in a wide-ranging seabird [0.03%]
纬度驱动的远洋海鸟昼夜节律变化的证据
Natasha Gillies,Sebastien Descamps,Nicholas Per Huffeldt et al.
Natasha Gillies et al.
Diel rhythms synchronized to Earth's photic cycle are near-ubiquitous among animals living in regions with distinct day-night cues. Where such cues are reduced or absent, however, activity patterns may weaken, reorganize or become decoupled...
Discovery of the closest free-living relative of the domesticated 'magic mushroom' Psilocybe cubensis in Africa [0.03%]
非洲发现最接近致幻“魔法蘑菇”Psilocybe cubensis的近亲物种
Alexander James Bradshaw,Cathy Sharp,Breyten Van Der Merwe et al.
Alexander James Bradshaw et al.
The psychedelic mushroom Psilocybe cubensis is cultivated worldwide for recreational and medicinal use. Described initially from Cuba in 1906, there has been substantial debate about its origin and diversification. The prevailing view is th...
Towards a causal understanding of bidirectional effects in ecology and evolution [0.03%]
走向因果地理解生态学和进化中的双向效应

Sam F Walmsley
Feedback loops govern many processes in the natural world and are ubiquitous in ecology and evolutionary biology. Despite their prevalence in theory, however, feedbacks and other forms of reciprocal causation are rarely quantified by empiri...
