The rise of ants over the past ~100 million years reshaped the biosphere, presenting ecological challenges for many organisms, but also opportunities. No insect group has been so adept at exploiting niches inside ant colonies as the rove beetles (Staphylinidae) - a global clade of>64,000 predominantly free-living predators from which numerous socially parasitic 'myrmecophile' lineages have emerged. Myrmecophilous staphylinids are specialized for colony life through changes in behavior, chemistry, anatomy, and life history that are often strikingly convergent, and hence potentially adaptive for this symbiotic way of life. Here, we examine how the interplay between ecological pressures and molecular, cellular, and neurobiological mechanisms shape the evolutionary trajectories of symbiotic lineages in this ancient, convergent system.
在过去的大约 1 亿年中，蚂蚁的兴起重塑了生物圈，给许多生物带来了生态挑战，但也带来了机遇。没有哪个昆虫群体像隐翅虫（隐翅虫科）那样擅长在蚁群中开拓小生境——这是一个全球性的 64000 多个主要自由生活的捕食者群体，其中许多社会性寄生的“蚁友”谱系已经出现。通过行为、化学、解剖和生活史的变化，拟寄生隐翅虫类专门适应群体生活，这些变化往往惊人地趋同，因此可能适应这种共生的生活方式。在这里，我们研究了生态压力与分子、细胞和神经生物学机制之间的相互作用如何塑造这个古老的、趋同的系统中共生谱系的进化轨迹。
