The evolutionary history of dynastes beetles, which can be found in both north and south americas and exhibit two different altitudinal preferences (highland and lowland) is tested for the effects of biotic interchange between continents and different ecological preferences on the rate of species diversification additionally, the hypotheses of .
In conclusion: the diversity of ambrosia beetles has not been generated by cospeciation with the tree hosts, neither by parapatric speciation of disjunct populations it seems likely that factors such as the altitudinal differentiation, or allopatric speciation played more creative roles.

Herbivorous insects are remarkably species-diverse, and the cause of such diversity remains a classical issue in the fields of ecology and evolution the traditional explanation for the huge diversity of such insects is that repeated dietary changes over evolutionary time provided opportunities for .
This extends to insects a correlation between plant and animal diversity, already well established for birds and possibly true for lizards and rodents it leaves open the unresolved question as to whether plant structure or plant species diversity is more important. Rapid diversification of male genitalia in ohomopterus ground beetles may have resulted from two different sexual selection processes: intersexual selection (sexual conflict or cryptic female choice) and intrasexual selection (sperm competition) in the intersexual process, a longer copulatory piece may have improved spermatophore deposition .
