File: dataset_multimodel_open_area_sp (txt file)<br>Contents overview: Survey data on landscape variables and bird diversity (hill numbers) to open area birds sampled species in 30 plots between natural and agricultural areas in the Caatinga region, Northeast Brazil. <br>Plot: Sampling units were identified by the three study areas. AL: PPN Faz. Almas; SJ: Estação Experimental de São João do Cariri; SP: Faz. São Paulo dos Dantas.fragmentation: Spatial arrangement metric. Forest fragmentation is expressed by the number of forest fragments per hectare.Densi_borda: Edge density as the linear length of forest cover and woodlands measured in km. habitat_amount: Habitat amount for which we consider the proportion of forest cover and woodlands.Heteroge: Landscape heterogeneity considering the Shannon index of land use (landscape diversity per ha). q0: Representation of the total number of species (species richness). A list of open-area birds is considered.q1: Representation of the species weighted according to their abundance and the number of ‘common’ species in the community. A list of open-area birds is considered.q2: Representation of the abundances squared, giving more weight to dominant species, thus representing the number of ‘dominant’ species in the community. A list of open-area birds is considered.
