Area effect on bird communities, guilds and species in a highly fragmented forest landscape of central Italy

摘要: Abstract Breeding bird communities in an “archipelago” of 16 wood fragments (13 oak deciduous woods, 1 holm wood, and 2 anthropogenic pinewoods) a littoral plain Central Italy were studied. Species richness diversity index resulted directly significantly correlated to fragment area. tended cumulate over 100‐ha area size. The log‐transformed species/area relationship showed coefficient z = 0.21, inside the range known for ecological islands. Z increased (0.23) excluding one guild field‐edge anthropophilous species. Cluster analysis separation among based on their Although species pinewood plantations corresponded expected from relationship, cluster highlighted disaffinity with larger woods oaks. These could not be surrogate habitats many forest fragmented landscapes. Richness abundance a...
