| description | The expansion of anthropogenic activities drives changes in the composition,
structure, and spatial configuration of natural landscapes, influencing both the taxonomic
and functional diversity of bird communities. This pattern is evident in the Colombian Amazon,
where agricultural and livestock expansion has altered ecological dynamics, avifaunal
assemblages, and the provision of regulating ecosystem services. This study analyzed
the influence of agroforestry (cocoa-based agroforestry systems—SAFc) and silvopastoral
systems (SSP) on the functional diversity of birds and their potential impact on ecosystem
services in eight productive landscape mosaics within the Colombian Amazon. Each mosaic
consisted of a 1 km2 grid, within which seven types of vegetation cover were classified, and
seven landscape metrics were calculated. Bird communities were surveyed through visual
observations and mist-net captures, during which functional traits were measured. Additionally,
functional guilds were assigned to each species based on a literature review. Five
multidimensional indices of functional diversity were computed, along with communityweighted
means per guild. A total of 218 bird species were recorded across both land-use
systems. Bird richness, abundance, and functional diversity—as well as the composition of
functional guilds—varied according to vegetation cover. Functional diversity increased in
mosaics containing closed vegetation patches with symmetrical configurations. Variations
in functional guilds were linked to low functional redundancy, which may also lead to
differences in the provision of regulating ecosystem services such as biological pest control
and seed dispersal—both of which are critical for the regeneration and connectivity of
productive rural landscapes. In conclusion, functional diversity contributes to the resilience
of bird communities in landscapes with Amazonian agroforestry and silvopastoral systems,
highlighting the need for landscape management that promotes structural heterogeneity to
sustain regulating ecosystem services and ecological connectivity. |
