Wilhelm in Papua New Guinea. The north slopes of Mt. Wilhelm, the highest peak in Papua New Guinea, support a complete elevational gradient of relatively undisturbed rainforest, from 200 m to the tree line at 3,700 m. Based on field work in 2010 and 2012 over the Mt. Wilhelm elevational gradient, we report novel distribution data for 43 species, including geographic and elevational range extensions, demographic data, and new records of species poorly known in New Guinea. Our new data regarding avian distributions reveal that New Guinea continues to be an excellent theatre to study diversification, competition and community structure. We recorded many extensions to upper elevational ranges (7% of the total number of species), which is especially surprising considering the elevational distance of 500 m between sites, resulting in significant under-estimation of limits at in-between elevations, and that we did not consider potential extensions of < 100 m as significant. However, our main caveat is the absence of historical data for Mt. Wilhelm. Our new elevational records suggest that some species are expanding upslope in response to climate change.
