Contaminants may affect ecosystem functioning by reducing the fitness of organisms and these impacts may cascade through ecosystems, particularly if the sensitive organisms are also habitat-forming species. Mariana Mayer-Pinto discusses how sub-lethal effects of toxicants can affect the quality and functions of biogenic habitats and why this is critical if we are to establish effective guidelines for protecting ecosystems.
