摘要: Reeve et al. (2016, Ecography, 39, 990–997) recently reported negative range–abundance relationships in Indo-Pacific bird communities and speculated that geographical isolation facilitates the evolution of broad-niched, small-ranged abundant species. We tested this relationship using a large independent data set on range abundance birds across New Caledonia (over 4,000 census points for 17,300 km²). In contradiction to 990–997), we found clear evidence are positive endemic species have narrower habitat niches than wide-range Our findings likely valid also other islands Indo-Pacific.
