In conclusion, we have shown that the predicted association between food and mate preference in phytophagous insects can readily evolve given selection for food preference in allopatry, but the maintenance of reproductive isolation after secondary contact is ultimately dependent on selection acting against hybrids, and/or mating taking place at the food resource.
Retention of the ability to recognise pheromone components that no longer signify conspecific females may assist in the maintenance of reproductive isolation of species.
The MRP likely is a critically important molecule in the establishment and maintenance of reproductive isolation among rotifer species [ 10].
They are sufficiently large, that if the species interbreed where they are sympatric, these barriers could play a role in the maintenance of reproductive isolation between them.
This document also included measures to enhance infection control and protect healthcare workers during maintenance of the isolation room and ventilation system.
If mating preferences contribute to the evolution and maintenance of reproductive isolation among species, mating signals are expected to change rapidly during the speciation process.
The lack of premating barriers suggests that, if individuals of these species frequently encounter one another in the areas where they coexist, post-mating barriers may play a role in the maintenance of reproductive isolation between them.
It is generally accepted that chromosomal rearrangements have the potential to limit introgression and thus facilitate the development and maintenance of reproductive isolation by means of suppressed recombination [ 16– 16].
It has been shown that chromosomal rearrangements have a potential to limit gene flow and thus facilitate the development and maintenance of reproductive isolation by means of suppressed recombination [ 16– 16].
Consequently, recessive autosomal loci acting in F2 and advanced generation hybrids contribute to the maintenance of reproductive isolation in the hybrid zone and may have played important roles in its establishment.
