Influence of herbivory and abiotic factors on the distribution of tall forbs along a productivity gradient: a transplantation experiment
In arctic‐alpine areas tall herb vegetation is restricted to sites with high productivity. At higher elevation, low prostate forbs and narrow‐leaved graminoids dominate the vegetation in sites with a protecting snow cover during winter. In this study, I test whether herbivory or abiotic factors prev...
