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 ...

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 ...

A new study of interbreeding between two species of howler monkeys in Mexico is yielding insights into the forces that drive the evolution of new species. A new University of Michigan study of ...

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 ...

Post-mating reproductive isolating mechanisms may be among the earliest reproductive barriers to emerge among incipient species. Trinidadian guppy, Poecilia reticulata, populations in the Caroni and ...

A paper published by URI researchers reveals key mechanisms in speciation in corals. Critically threatened by climate change, a better understanding of coral biology will help efforts to conserve and ...
