Supplementary data to article entitled A hotspot of groundwater amphipod
diversity on a crossroad of evolutionary radiations Groundwater harbours
an exceptional fauna and provides invaluable ecosystem services, yet is
among the least explored and consequently least protected ecosystems.
Successful protection of its biodiversity depends on complete species
inventories, knowledge of species spatial distribution, and quantification
of biodiversity patterns, as well as disentanglement of the processes that
shaped biodiversity patterns. We studied the hyper-speciose amphipod
genus Niphargus as a model system within a global subterranean
biodiversity hotspot, the Western Balkans (Europe). We linked the
biodiversity patterns with possible underlying processes and discuss the
needs to include information on different origins of biodiversity into
conservation approaches. We analysed biodiversity patterns
of Niphargus using two biodiversity metrics, species richness and
phylogenetic diversity, on a grid-based approach. To account for high
cryptic diversity, we replaced nominal species with taxonomic units
identified in unilocus delimitations (MOTUs). We built a time-calibrated
multilocus phylogeny of 512 Niphargus MOTUs from within and outside the
study area, and calculated Faith's phylogenetic diversity,
standardized effect sizes of phylogenetic diversity, and residual of
phylogenetic diversity regressed onto species richness. Within the study
area, we recognized 245 MOTUs, belonging to different Niphargus clades.
Species richness is highest in a north-western hotspot, although some
species-rich cells were detected also in the south-east. High phylogenetic
diversity coincides with high species richness in the north-west, while in
the south-east it is lower than expected. We have shown that species
richness does not predictably correlate with phylogenetic diversity. This
difference suggests that different processes have led to the formation of
species-rich areas in the Western Balkans: through a combination of
dispersal and speciation in the north-west, and local radiation in the
south-east, respectively. This calls for caution in conservation
strategies relying solely on number of species and may change the view on
conservation priorities within this region. The dataset includes R-script,
together with all raw data needed to reproduce the analyses: File
"beast_analysis.xml" includes alignments and settings used for
BEAST2 analysis. R script "20220124_niphargus_wbalkans.R"
includes the code used in production of diversity pattern analyses. To run
the script set working directory (commented) and unzip the
"data" folder in the working directory. Folder
"data.zip" includes raw data needed to run the script:
species_occurence.csv, map shape files and beast.tree file.
