Steven P Brady et al.
Evolutionary biologists tend to approach the study of the natural world within a framework of adaptation, inspired perhaps by the power of natural selection to produce fitness advantages that drive population persistence and biological dive...
Tracking genetic invasions: Genome-wide single nucleotide polymorphisms reveal the source of pyrethroid-resistant Aedes aegypti (yellow fever mosquito) incursions at international ports [0.03%]
追踪基因入侵：全基因组单核苷酸多态性揭示了国际港口输入的黄热病蚊子（埃及伊蚊）抗联苯菊酯基因的来源

Resistance to new antimicrobials can become widespread within 2-3 years. Resistance problems are particularly acute for bacteria that can experience selection as both harmless commensals and pathogenic hospital-acquired infections. New drug...
Divergent transcriptomic signatures in response to salinity exposure in two populations of an estuarine fish [0.03%]
两种鱼对盐度暴露产生不同的转录组反应签名

Rodolfo Jaffé et al.
Habitat degradation and climate change are currently threatening wild pollinators, compromising their ability to provide pollination services to wild and cultivated plants. Landscape genomics offers powerful tools to assess the influence of...
A transcriptional and functional analysis of heat hardening in two invasive fruit fly species, Bactrocera dorsalis and Bactrocera correcta [0.03%]
两种入侵性果实蝇物种Bactrocera dorsalis和Bactrocera correcta的热硬化转录及功能分析
