Resumo(s)
Aims: Understanding fine-grain
diversity patterns across large spatial extents is
fundamental for macroecological research and biodiversity conservation. Using
the GrassPlot database, we provide benchmarks of fine-grain
richness values of
Palaearctic open habitats for vascular plants, bryophytes, lichens and complete vegetation
(i.e., the sum of the former three groups).
Location: Palaearctic biogeographic realm.
Methods: We used 126,524 plots of eight standard grain sizes from the GrassPlot
database: 0.0001, 0.001, 0.01, 0.1, 1, 10, 100 and 1,000 m2 and calculated the mean
richness and standard deviations, as well as maximum, minimum, median, and first
and third quartiles for each combination of grain size, taxonomic group, biome, region,
vegetation type and phytosociological class.
Results: Patterns of plant diversity in vegetation types and biomes differ across grain
sizes and taxonomic groups. Overall, secondary (mostly semi-natural)
grasslands and
natural grasslands are the richest vegetation type. The open-access
file ”GrassPlot
Diversity Benchmarks” and the web tool “GrassPlot Diversity Explorer” are now
available online (https://edgg.org/datab ases/Grass landD ivers ityEx plorer) and provide
more insights into species richness patterns in the Palaearctic open habitats.
Conclusions: The GrassPlot Diversity Benchmarks provide high-quality
data on species
richness in open habitat types across the Palaearctic. These benchmark data
can be used in vegetation ecology, macroecology, biodiversity conservation and data
quality checking. While the amount of data in the underlying GrassPlot database and their spatial coverage are smaller than in other extensive vegetation-plot
databases,
species recordings in GrassPlot are on average more complete, making it a valuable
complementary data source in macroecology
