Landscape fragmentation shrinks bird song repertoire in small habitat patches

Evidence

In this species, studied by Laiolo et al. (2008), a significant relationship between the structure of a landscape and the complexity of its song repertoire has been found. The overall song diversity results from the variation among populations (betacultural diversity). Song dissimilarity and distance between subpopulations evidently agreed, and the same result was found between individual song diversity and patch area. A distance of only 5 km was found sufficient to characterize a specific cultural tradition in song repertoire. The smaller patches had the poorer song repertoire. — Almo Farina, Soundscape Ecology, 226
