Pressure for rapid and accurate mate recognition promotes avian-perceived plumage sexual dichromatism in true thrushes (genus: Turdus) [0.03%]
求偶识别的快速准确促进真莺雀属（山椒鸟属）鸟类眼感知的两性羽毛色彩差异

Ecological conditions limiting the time to find a compatible mate or increasing the difficulty in doing so likely promote the evolution of traits used for species and mate recognition. In addition to interspecific character displacement sig...
Phylogenetic and environmental patterns of sex differentiation in physiological traits across Drosophila species [0.03%]
果蝇多种生理特征的性别分化模式及其环境差异分析

Vanessa Kellermann et al.
Sex-based differences in physiological traits may be influenced by both evolutionary and environmental factors. Here we used male and female flies from >80 Drosophila species reared under common conditions to examine variance in a number of...
The effect of migration and variation on populations of Escherichia coli adapting to complex fluctuating environments [0.03%]
迁移和变异对大肠杆菌适应复杂波动环境的种群的影响

Migration, a critical evolutionary force, can have contrasting effects on adaptation. It can aid as well as impede adaptation. The effects of migration on microbial adaptation have been studied primarily in simple constant environments. Ver...
Measuring, comparing and interpreting phenotypic selection on floral scent [0.03%]
表型选择在花香上的测量、比较与解读
Øystein H Opedal,Karin Gross,Elodie Chapurlat et al.
Øystein H Opedal et al.
Natural selection on floral scent composition is a key element of the hypothesis that pollinators and other floral visitors drive scent evolution. The measure of such selection is complicated by the high-dimensional nature of floral scent d...
Signal detection shapes ornament allometry in functionally convergent Caribbean Anolis and Southeast Asian Draco lizards [0.03%]
信号检测塑造了加勒比岛壁虎与东南亚 Draco蜥蜴功能收敛的装饰几何学关系

Visual ornaments have long been assumed to evolve hyper-allometry as an outcome of sexual selection. Yet growing evidence suggests many sexually selected morphologies can exhibit other scaling patterns with body size, including hypo-allomet...
Static allometries do not reflect evolutionary allometry in exaggerated weaponry of male New Zealand sheetweb spiders (Cambridgea spp.) [0.03%]
静态等比例关系并不反映新西兰网蜘蛛雄性夸张武器的进化几何关系(Cambridgea属)

Across the animal kingdom, exaggerated weaponry is frequently used by one sex to contest access for potential mates. Within species, if disproportionate investment in weaponry confers an advantage to larger individuals, this may result in p...
Arms race and fluctuating selection dynamics in Pseudomonas aeruginosa bacteria coevolving with phage OMKO1 [0.03%]
与OMKO1噬菌体共同进化的铜绿假单胞菌中的军备竞赛和动态选择波动
Kaitlyn E Kortright,Benjamin K Chan,Benjamin R Evans et al.
Kaitlyn E Kortright et al.
Experimental evolution studies have examined coevolutionary dynamics between bacteria and lytic phages, where two models for antagonistic coevolution dominate: arms-race dynamics (ARD) and fluctuating-selection dynamics (FSD). Here, we test...
Inferring the demographic history of the North American firefly Photinus pyralis [0.03%]
北美发光蠕虫Photinus pyralis的种群历史推断
Ana Catalan,Sebastian Höhna,Sarah E Lower et al.
Ana Catalan et al.
The firefly Photinus pyralis inhabits a wide range of latitudinal and ecological niches, with populations living from temperate to tropical habitats. Despite its broad distribution, its demographic history is unknown. In this study, we mode...
A novel neo-sex chromosome in Sylvietta brachyura (Macrosphenidae) adds to the extraordinary avian sex chromosome diversity among Sylvioidea songbirds [0.03%]
一种新的新性染色体：Sylvietta brachyura（ Macrosphenidae）为 Sylvioidea鸣鸟中非凡的鸟类性染色体多样性增添了新的内容
Hanna Sigeman,Hongkai Zhang,Salwan Ali Abed et al.
Hanna Sigeman et al.
We report the discovery of a novel neo-sex chromosome in an African warbler, Sylvietta brachyura (northern crombec; Macrosphenidae). This species is part of the Sylvioidea superfamily, where four separate autosome-sex chromosome translocati...
Evolution of immune function in response to dietary macronutrients in male and female decorated crickets [0.03%]
食物宏量营养物质对雄性和雌性饰腹步甲免疫功能进化的影响
Corinne Letendre,Alejandro Rios-Villamil,Alexandria Williams et al.
Corinne Letendre et al.
Although dietary macronutrients are known to regulate insect immunity, few studies have examined their evolutionary effects. Here, we evaluate this relationship in the cricket Gryllodes sigillatus by maintaining replicate populations on fou...
