代内可塑性与跨代可塑性对性状表达的影响知之甚少，但对评估可塑性的进化后果很重要。我们测试了遗传学，代内可塑性和跨代可塑性如何共同塑造影响田间蟋蟀Teleogryllus oceanicus快速进化的性状。在夏威夷人口攻击的声音定向寄生蝇，一个保护性的，X连锁的变体（“flatwing”）消除男性的声音性信号。沉默的男性迅速蔓延到固定，大大改变了声学环境。首先，我们发现了支持青少年平翅相关多效性的证据：纯繁殖的平翅雄性和雌性比正常翅基因型的表现出更大的运动。第二，代内可塑性造成同性恋flatwingfemales发展在沉默中，模仿所有flatwing人口，达到较低的成年人的身体状况和生殖投资比那些实验暴露于歌曲。第三，母亲的歌曲暴露会导致后代的跨代可塑性，影响成年人而不是青少年的体型、状况和生殖投资。这与行为特征形成对比，行为特征只受代内可塑性的影响。第四，我们匹配和不匹配的母亲和后代的社会环境，发现跨代可塑性有时与代内可塑性相互作用，有时相反。我们的研究结果强调，在评估其适应性后果和作用时，评估不同性状和阶段的可塑性跨代的重要性。
The effects of within-generation plasticity vs. transgenerational plasticity on trait expression are poorly understood, but important for evaluating plasticity’s evolutionary consequences. We tested how genetics, within-generation plasticity, and transgenerational plasticity jointly shape traits influencing rapid evolution in the field cricketTeleogryllus oceanicus. In Hawaiian populations attacked by acoustically orienting parasitoid flies, a protective, X-linked variant (“flatwing”) eliminates male acoustic sexual signals. Silent males rapidly spread to fixation, dramatically changing the acoustic environment. First, we found evidence supportingflatwing-associated pleiotropy in juveniles: pure-breedingflatwingmales and females exhibit greater locomotion than those withnormal-winggenotypes. Second, within-generation plasticity caused homozygous-flatwingfemales developing in silence, which mimics all-flatwing populations, to attain lower adult body condition and reproductive investment than those experimentally exposed to song. Third, maternal song exposure caused transgenerational plasticity in offspring, affecting adult, but not juvenile, size, condition, and reproductive investment. This contrasted with behavioral traits, which were only influenced by within-generation plasticity. Fourth, we matched and mismatched maternal and offspring social environments and found that transgenerational plasticity sometimes interacted with within-generation plasticity and sometimes opposed it. Our findings stress the importance of evaluating plasticity of different traits and stages across generations when evaluating its fitness consequences and role in adaptation.
