The formation and maintenance of species in nature is accomplished by the evolution of reproductive isolating mechanisms. To understand patterns of speciation and coexistence between species, it is ...

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

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 ...

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 ...

Hendry's team observed that male river sockeyes are slimmer than their lake counterparts (to better deal with the river's strong current), while the female river sockeye are larger than their beach ...
