Abstract
Diversity-dependent cladogenesis occurs when a colonizing lineage exhibits increasing interspecific competition as it ecologically diversifies. Repeated colonization of a region by closely-related taxa may cause similar effects as species within each lineage compete with one another. This may be particularly relevant for secondary colonists, which could experience limited diversification due to competition with earlier, already diversified colonists, in other words, the incumbent colonists. This potential mechanism through which ecological opportunity can be limited has been poorly studied in spatially-limited oceanic island systems. We tested the hypothesis that an incumbent lineage may diminish the diversification of secondary colonists in two speciose clades of Philippine ?Old Endemic? murine rodents?Phloeomyini and Chrotomyini?on the relatively old oceanic island of Luzon. Although phylogenetic analyses confirm the independent, non-contemporaneous colonization of Luzon by the ancestors of these two clades, we found no support for arrested diversification in either, instead inferring that their diversification resulted from constant-rate processes that were either uniform or favoring Chrotomyini, depending on the method used. Our results suggest that ecological incumbency has not played an important role in determining lineage diversification among Luzon murines, despite sympatric occurrence by constituent species within each lineage, and a substantial head start for the primary colonists, the Phloeomyini.
