Precipitation mediates termite functional diversity and dominance in southern Africa
https://doi.org/10.5061/dryad.pnvx0k6xj
Give a brief summary of dataset contents, contextualized in experimental procedures and results.
Description of the data and file structure
Southern Africa contains roughly 54 genera and 165 species of termites, which represents nearly 20% of 280 termite genera known globally (Uys 2002). In this study, we aim to 1) characterise termite functional prevalence, distribution and diversity across the bioclimatic and elevation gradients of southern Africa; and 2) assess the effect of precipitation on termite functional diversity and assemblage composition.
The spreadsheet includes 18 fields :
- TARGET_FID: unique identifier for grid cell. The grid cell is quarter degree square (0.25° x 0.25°, or 50 x 50 km).
- POINT_X: latitude of grid cell centroid
- POINT_Y: longitude of grid cell centroid
- Ecoregion: Ecoregion of grid cell centroid as described in Olson et. al 2001 (Olson, D.M., Dinerstein, E., Wikramanayake, E.D., Burgess, N.D., Powell, G.V., Underwood, E.C., J.A., D'amico, I., Itoua, H.E., Strand, J.C., Morrison, C.J.
