Consumer impacts on ecosystem functions in coastal wetlands: The data gap

Abstract

Abstract Over the last 30 yr, our understanding of the factors that control the structure and function of coastal wetlands has shifted from a narrative that focused on bottom‐up control to one that explicitly includes top‐down factors. However, the emphasis of this transition has been on how consumers influence wetland vegetation; comparatively, few studies evaluate how consumers influence broader ecosystem properties and functions such as nutrient cycling and decomposition while fewer still investigate how trophic interactions affect these relationships. Here, we review the literature on consumer impacts on coastal wetland ecosystems and highlight areas where additional studies are sorely needed. It is our hope that identifying the current gaps in our knowledge will provide additional impetus for the study of community and ecosystem ecology within these globally important ecosystems.
