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 ...

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 ...

To what degree is the divergent adaptation responsible for life's phenotypic variety also responsible for generating the millions of species that manifest this variation? Theory predicts that ...

When two organisms typically do not interbreed with one another, they are considered different species. But what are the reproductive barriers that isolate one population from another? Hear the ...

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 ...
