Habitat fragmentation is considered to be one of the greatest threats to biodiversity of our time. However, there are few studies addressing how the different biodiversity metrics (namely – taxonomic, phylogenetic and functional diversity) react to the habitat fragmentation when comparing one to another, and how the impact of habitat fragmentation on biodiversity could be mediated by the social public information. Our goal was to examine how the biodiversity metrics of bird communities in forest patches change with the increasing isolation of those patches, and how those changes could be mediated by manipulating social information. To answer that, we have inspected over 150 forest patches in Central Europe. For each bird community inhabiting a given patch, measures of phylogenetic and functional diversity were calculated. After that we have conducted a large scale behavioral landscape experiment, where we have broadcasted a different types of social information on those stands. Different measures of diversity reacted in a different way to changes in the parameters describing habitat patch fragmentation. Social information was able to mediate the effects of patch size and isolation. Our research helps to understand the importance of individual patches of forest habitats in the farmland for the preservation of biodiversity.
