founder effects initiated rapid species radiation in hawaiian cave planthoppers. | the hawaiian islands provide the venue of one of nature's grand experiments in evolution. here, we present morphological, behavioral, genetic, and geologic data from a young subterranean insect lineage in lava tube caves on hawai'i island. the oliarus polyphemus species complex has the potential to become a model for studying rapid speciation by stochastic events. all species in this lineage live in extremely similar environments but show strong differentiation in behavioral and morphometric cha ... | 2013 | 23696661 |
