Inhibitory analysis of regulatory interactions in trophic webs

It should be noted that many chemical agents suppress the trophic activity of daphnia even
at concentrations having no negative effect on the phytoplankton algal populations. This is
true for many pesticides (endosulfan, diazinon, methylparathion, atrazin, lindan, dichlobenyl,
