README - description of the corrections introduced to this version ------------------------------------------------------------------- This data include corrected information on the abundances of gallers from Mikulcice sampling site (included in “Mikulcice_gallers” sheet). Some species of gallers were extremely abundant at this site, making the complete sampling of individual galls they induced impossible. In such cases, we used partial sampling and estimated the percentage of leaves attacked by the respective gallers. Using the total number of leaves inspected for herbivores, we used these values to estimate their total abundance on the respective tree. Unfortunately, wrong leaf numbers were used for the estimate in the previous version of the data. Abundances of some galler species from Mikulcice sites were over-estimated due to this error. This error does not affect the findings of our associated publication. However, it could potentially introduce a bias in any future analyses using these data. Only this version of the data should be used for any abundance based analyses using the galler data.
