This study found a pattern of niche conservatism in the Eurasian snowfinch lineage, except for a dramatic niche evolution event in Montifringilla nivalis. Interestingly, this species, which has the broadest geographic distribution among snowfinches, may have experienced an evolutionary change in niche characteristics that facilitated its westward range expansion.
This study explores the evolutionary history of ecological niche characters in the Eurasian snowfinch lineage. Specifically, we use new analytical approaches to reconstruct ecological niche evolution, taking into account uncertainty in knowledge of the ecological niche limits. We found an overall pattern of niche conservatism in relation to both temperature and precipitation characteristics of niches, but for one dramatic niche evolution event, in Montifringilla nivalis. Interestingly, this species is also that which has the broadest geographic distribution among snowfinches. We conclude that an evolutionary change in niche characteristics perhaps within M. nivalis (i.e. present in some and not all of its populations) made possible the broad, westward range expansion of that species, thus changing dramatically the distributional potential of the snowfinch lineage.
