The detectability half-life in arthropod predator-prey research: what it is, why we need it, how to measure it, and how to use it.

abstract：:All species of the genus Populus (poplar, aspen) are dioecious, suggesting an ancient origin of this trait. Despite some empirical counter examples, theory suggests that nonrecombining sex-linked regions should quickly spread, eventually becoming heteromorphic chromosomes. In contrast, we show using whole-genome scans...
