Spatial scaling of plant and bird diversity from 50 to 10,000 ha in a lowland tropical rainforestNARA Subscribed
While there are numerous studies of diversity patterns both within local communities and at regional scales, the intermediate scale of tens to thousands of km 2 is often neglected. Here we present detailed local data on plant communities (using 20 × 20 m plots) and bird communities (using point counts) for a 50 ha ForestGEO plot in lowland rainforest at Wanang, Papua New Guinea. We compare these local diversity patterns with t...
Habitat use of breeding birds in Central European reed bedsNARA Subscribed
Aim Among the world's three major nectar‐feeding bird taxa, hummingbirds are the most phenotypically specialized for nectarivory, followed by sunbirds, while the honeyeaters are the least phenotypically specialized taxa. We tested whether this phenotypic specialization gradient is also found in the interaction patterns with their floral resources. Location Americas, Africa, Asia and Oceania/Australia. Methods We compiled inter...
Unusual abundance–range size relationship in an Afromontane bird community: the effect of geographical isolation?NARA Subscribed
Aim To show that the frequently reported positive trend in the abundance–range‐size relationship does not hold true within a montane bird community of Afrotropical highlands; to test possible explanations of the extraordinary shape of this relationship; and to discuss the influence of island effects on patterns of bird abundance in the Cameroon Mountains. Location Bamenda Highlands, Cameroon, Western Africa. Methods We censuse...
