Nectar robbing rather than pollinator availability constrains reproduction of a bee-flowered plant at high elevations

The files contain data on the floral ecology of Clinopodium alpinum collected along an elevational gradient in the Berchtesgaden National Park in Germany in 2017. The data are presented in the work entitled \"Nectar robbing rather than pollinator availability constrains reproduction of a bee-flowered plant at high elevations\" by Patrick L. Kohl and Ingolf Steffan-Dewenter. Files include data on flower visitor observations (including raw data on the number of visits by individual specifmens), data on seed/ovule ratios (both open pollinated and bagged flowers), data on the incidence of nectar robbing by bumble bees (the frequency of corolla perforations) and of flower herbivory by Eulophidae, and data on basic flowering traits of C. alpinum (number of flowers per inflorescence, corolla tube length, display size)., The methods of how the data were collected are described in the work entitled \"Nectar robbing rather than pollinator availability constraints reproduction of a bee-flowered plant at high elevations\" by Patrick L. Kohl and Ingolf Steffan-Dewenter, The precise data file content is described in the \"README.txt\" document.
