In this project we analyse ecomorphological traits of frugivorous birds and fleshy fruits in the Peruvian Andes along an elevational gradient. The main emphasis is on (1) changes in phylogenetic and trait diversity with elevation, (2) on the co-variation between trait diversity of frugivorous birds and fleshy fruits, and (3) on the effects of bird and fruit traits on the structure of plant-frugivore networks. We combine field work and morphological measurements of study skins with recent analytic tools from phylogeny and network theory to identify mechanisms that underlie the high diversity of frugivorous birds in the tropical Andes. Such information is important to assess the resilience of diverse bird and plant communities against rapidly changing climates in tropical mountain ecosystems.
