Effects of landscape structure on bird functional diversity

This dataset and R code support a study about the effects of landscape structure on the functional diversity of bird assemblages in the Upper Magdalena River Valley, Colombia. The research explores how habitat loss and fragmentation impact bird communities by analyzing functional traits across different land-use gradients. Bird abundance data were collected through mist nets, point counts and eBird records, while functional traits were obtained from the AVONET database. The dataset includes morphological and ecological trait data, landscape metrics and functional diversity indices. The provided R scripts enable users to conduct statistical analyses, including functional diversity calculations, generalized linear models (GLMs), and multivariate analyses (PCA, db-RDA, RLQ and fourth-corner analysis).
