Speciation occurs when reproductive barriers substantially reduce gene flow between lineages. Understanding how specific barriers contribute to reproductive isolation offers insight into the initial ...

Female giant water bugs lay their eggs on a male's back after mating and the male takes care of the eggs until the nymphs are hatched, a couple of weeks later. A study led by Dr. Tomoya Suzuki of ...

Hybrid sterility and reproductive isolation represent critical challenges for rice breeding programmes, as these biological barriers restrict the successful fusion of diverse genetic backgrounds. By ...

Thus, body size directly mediates reproductive isolation through its influence on both intersexual compatibility and intrasexual competition. Our results confirm that divergent natural selection ...
