Light, wind, and touch influence leaf chemistry and rates of herbivory in Apocynum cannabinum (Apocynaceae)Download
Simply visiting and manipulating plants in a way consistent with measurement in typical ecological studies influences the amount of leaf herbivory experienced by some plant species. We examined the mechanistic basis for why Apocynum cannabinum is particularly responsive to such visitation and...
Prevalence and predictability of handling effects on plants in field studies: Results from field experiments and a meta-analysisDownload
Various effects on plant growth associated with handling or touching plants are well documented from greenhouse and laboratory studies, but are generally unknown or ignored under field conditions. We examined the prevalence of the effects of handling, at levels typical of many ecological...
Separate effects of human visitation and touch on plant growth and herbivory in an old-field communityDownload
Although animal scientists have long been aware that methods used to measure an experimental system can affect the subject of measurement, similar confounding effects of commonly used field methods have only recently been acknowledged by plant ecologists. Here we demonstrate significant effects...
