Species richness [Diversity]


Variance of species richness for all vascular species on 100 m² plots. (ID=11)
(created by Ute Schmiedel)
Boxplot shows variance of species richness for all vascular species on 20 plots of 100 m² on the Observatory S22 (Soebatsfontein).
Variance of species richness for perennial species (herbs / grasses, shrubs and trees) on 100 m² plots over the years. (ID=12)
(created by Ute Schmiedel)
Boxplot shows the inter-annual variance of species richness for perennial species (herbs / grasses, shrubs and trees) on 20 plots of 100 m² on the biodiversity observatory S22 Soebatsfontein.

Shannon diversity [Diversity]


Variance of Shannon diversity index for all vascular species on 100 m² plots over the years. (ID=13)
(created by Ute Schmiedel)
Boxplot shows the inter-annual variation of the Shannon diversity index for all vascular species on 20 plots of 100 m² in size on the biodiversity observatory S22 Soebatsfontein. Horizontal bold line = median, box = lower and upper quartile, whiskers = minimum and maximum.
Variance of Shannon diversity index for perennial species (herbs / grasses, shrubs and trees) on 100 m² plots over the years. (ID=14)
(created by Ute Schmiedel)
Boxplot shows the inter-annual variation of the Shannon diversity index for perennial species (herbs / grasses, shrubs and trees) on 20 plots of 100 m² in size on the biodiversity observatory S22 Soebatsfontein. Horizontal bold line = median, box = lower and upper quartile, whiskers = minimum and maximum.

Pielou's evenness [Diversity]


Variance of Pielou's evenness index for all vascular species on 100 m² plots over the years. (ID=15)
(created by Ute Schmiedel)
Boxplot shows the inter-annual variation of the Pielou's evenness index for all vascular species on 20 plots of 100 m² in size on the biodiversity observatory S22 Soebatsfontein. Horizontal bold line = median, box = lower and upper quartile, whiskers = minimum and maximum.
Variance of Pielou's evenness index for all perennial species (herbs, grasses, shrubs and trees) on 100 m² plots over the years. (ID=16)
(created by Ute Schmiedel)
Boxplot shows the inter-annual variation of the Pielou's evenness index for all perennial species (herbs, grasses, shrubs and trees) on 20 plots of 100 m² in size on the biodiversity observatory S22 Soebatsfontein. Horizontal bold line = median, box = lower and upper quartile, whiskers = minimum and maximum.

Rainfall [Climate]


Total rainfall per year for the observatory S22 Soebatsfontein. (ID=17)
(created by Ute Schmiedel)
Total rainfall [mm] per year for the observatory S22 Soebatsfontein as measured by the SASSCAL Weather Station next to the observatory.
Variance of monthly rainfall per year. (ID=68)
(created by Ute Schmiedel)
Boxplot shows the variance of monthly rainfall per year for the observatory S22 Soebatsfontein. Data was provided by the SASSCAL Weather Station at the observatory. Horizontal bold line = median, box = lower and upper quartile, whiskers = minimum and maximum.

SPEI [Climate]


Standardised Precipitation-Evapotranspiration Index (SPEI) for a 12-months interval. (ID=67)
(created by Ute Schmiedel)
The SPEI index is a standardised monthly climatic balance computed as the difference between the cumulative precipitation and the potential evapotranspiration (Vicente-Serrano et al. 2010). For this presentation the SPEI value per month is based on the accumulated values of the previous 12 months. Red bars indicate drought, blue bars humid conditions.
