Current status and future prospects for the assessment of marine and coastal ecosystem services: a systematic review.

Background: Research on ecosystem services has grown exponentially during the last decade. Most of the studies have focused on assessing and mapping terrestrial ecosystem services highlighting a knowledge gap on marine and coastal ecosystem services (MCES) and an urgent need to assess them.

Methodology/principal Findings: We reviewed and summarized existing scientific literature related to MCES with the aim of extracting and classifying indicators used to assess and map them.
