Is there a dilution threshold as a function of distance or some general measure regarding the area around a plant that is under the influence of its phytochemicals? I'm looking for a objective value so I can proceed with a sample of aquatic macroinvertebrates in this area. I know it is something difficult to determine because of n factors, though any general, peer-reviewd information would be appreciated.

for them to see your comment. Though that is also not working so well for me here for some reason. $\endgroup$
