Abstract: | Despite the widely recognised importance of reserve networks, their effectiveness in encompassing and maintaining biodiversity
is still debated. Species diversity is one of the most affordable measures of biodiversity, but it is difficult to survey
such data over large scales. This research aimed to perform a sample-based assessment of species richness of groups of plants
with different conservation value (alien species, protected species, and all species) within a reserve network, testing the
use of partitioning as a tool for assessing diversity at different spatial scales, from the plot to the entire network. Plant
diversity patterns differed for the groups of species for most of the investigated spatial scales. Despite these patterns
assumed divergent tendencies when different species groups were considered, most of the species richness within the network
was given by larger scale β-diversity for both alien and protected species, as well for all species. Diversity partitioning
proved an effective tool to quantify the role of spatial scales in structuring the total species richness of the network,
and is helpful in planning reserve networks. |
