Herbivory on freshwater and marine macrophytes: a review and perspective [Aquatic Botany]

Keywords : climate change, conservation, ecosystem functions, grazing, seagrass, stoichiometry

by Frédéric Magné - published on

Until the 1990s, herbivory on aquatic vascular plants was considered to be of minor importance, and the predominant view was that freshwater and marine macrophytes did not take part in the food web: their primary fate was the detritivorous pathway. In the last 25 years, a substantial body of evidence has developed that shows that herbivory is an important factor in the ecology of vascular macrophytes across freshwater and marine habitats. Herbivores remove on average 40-48% of plant biomass in freshwater and marine ecosystems, which is typically 5-10 times greater than reported for terrestrial ecosystems.(...)
