    Description:
      Abstract: This chapter presents a summary of the extent and some of the controls and consequences of herbivory on benthic primary producers under pristine conditions (i.e. non affected by anthropogenic eutrophication).  It also analyses how increasing eutrophication, through the promotion of benthic algal growth and associated seagrass decline, may affect the intensity of herbivory on benthic communities.  The chapter is thus divided in two parts.  In the first part, using an extensive compilation of the literature,  I examine the variability in herbivory within and across pristine communities of microphytobenthos, macroalgae and seagrasses.  I also discuss some of the controls and consequences of herbivory on benthic producers under pristine conditions.  In the second part, I first comment on several considerations as to how the replacement of seagrasses by algae as dominant benthic producers following increased eutrophication may affect herbivory.  I then summarize what several experiments comparing the response of macrofaunal densities to macroalgal blooms following enhanced eutrophication have taught us.  I finish by discussing the changes in herbivory on benthic producers observed in two well-known ecosystems that have undergone intense eutrophication over the past few decades, Waquoit Bay (Massachusetts, USA) and the Venice Lagoon (Italy).  The chapter focuses on temperate systems, but reference to tropical systems is also made when pertinent and possible.  In choosing the tone of the chapter, I have intended to (1) review existing information relevant to the goals of the paper, (2) present hypotheses regarding the control of herbivory in pristine communities and how eutrophication may affect herbivory, and (3) suggest some recommendations for future research.
