A general signalling theory: why honest signals are explained by trade-offs rather than costs or handicaps [0.03%]
一种通用的信号理论：为什么诚实行为通过权衡而非成本或牺牲来解释

Honest signals have long posed a challenge for evolutionary biologists to explain. Here we propose a general Darwinian theory of signalling, Signalling Trade-Off Theory, to explain both honest and dishonest signalling based on recent theore...
Reproductive fluids enabling cryptic female choice of paternity do not induce concomitant ejaculate-mediated paternal effects in embryos of hybridizing salmonid fishes [0.03%]
生殖液体允许隐秘的雌性选择父系身份但不会诱导鲑鱼科杂交鱼类胚胎同时出现精子介导的父系效应

Post-ejaculatory sexual selection in the form of cryptic female choice provides opportunities for females to bias paternity to favor preferred males. However, little is known regarding how cryptic female choice might affect offspring outsid...
Genetic variance in reproductive timing contributes to trait evolvability [0.03%]

The additive genetic variance of a quantitative trait usually is interpreted as a measure of its evolvability, i.e., its capacity for adaptive evolution. However, in populations with overlapping generations, evolvability is also affected by...
Hidden genetic diversity among Blochmanniella endosymbionts of closely related carpenter ant populations [0.03%]
隶属于密切相关木蚁种群的Blochmanniella内共生菌的隐性基因多样性

Carpenter ants (Family Formicidae; Genus Camponotus) are a globally distributed, arboreal clade. They harbor an intracellular obligate bacterial endosymbiont known as "Candidatus Blochmanniella spp." (hereafter Blochmanniella). The host ant...

Climate change is known to influence biodiversity worldwide, with changes in organismal traits observed in many populations and species. Such effects are not universal, however, with some traits showing remarkable stability through time. Ti...

Darwin argued that natural selection leads organisms to appear as if they are striving to maximise their fitness. This idea is readily recognised at the individual cell or body level, but such adaptive design may also manifest at some highe...
Does genetic variation in controlled experiments predict phenology of wild plants? [0.03%]
可控实验中的基因变异能否预测野生植物的物候期？
Victoria L DeLeo,David L Des Marais,Claire M Lorts et al.
Victoria L DeLeo et al.
Phenology and the timing of development are often under selection. However, the relative contributions of genotype, environment, and prior developmental transitions to variance in the phenology of wild plants is largely unknown. Individual ...

The current economics of scientific publishing reveal a profound imbalance: academia pays prices far exceeding the actual costs of publication. Rather than supporting research, much of this expenditure sustains the profits of a few dominant...
