Factors determining species richness patterns of breeding birds along an elevational gradient in the Horn of Africa region.

ABSTRACT:

Aim

To document the species richness patterns of breeding birds along elevational gradients and explore its drivers in the Horn of Africa region.

Location

Horn of Africa region.

Taxon

Breeding birds.

Methods

Distributional data for breeding birds were collected. Elevational distribution data were extracted, interpolated, and assembled for all birds, passerines, and nonpasserines. In order to tease apart how different environmental factors contributed to the variation in species richness, we found it is necessary to divide the area into four subregions with different climatic regimes and topographic structure, namely western slope, eastern slope, wet side, and dry side. Then, the species richness in each 100-m elevational band was counted along the elevational g
