Ce document est un rapport technique relatif à l’état de la question dans le bassin méditerranéen. Il décrit les spécificités de la mer Méditerranée et le phénomène du changement climatique observé à l’échelle de cette région. Il présente ensuite les caractéristiques des cinq espèces de magnoliophytes présentes dans ses eaux.

This document is a summary of the technical report on the current state of affairs in the Mediterranean basin. It describes the specific characteristics of the Mediterranean Sea and the phenemenon of climate change observed on the scale of this particular region. It then presents five species of Magnoliophyta documented in its waters.

The purpose of this publication is to provide naturalists, resource managers and scientists with a simple guide to identify all species of seagrasses in the Red Sea. Each species is described in detail using photographs of key and diagnostic features. Key features are those that distinguish a particular species from most other species, whereas diagnostic features belong only to that species.

Seagrasses are flowering plants that thrive in shallow oceanic and estuarine waters around the world. Although there are only about 60 species of seagrasses worldwide, these plants play an important role in many shallow, near-shore, marine ecosystems. There is growing evidence that seagrasses are declining globally because of anthropogenic impacts. This paper presents an overview of seagrasses, the impacts of climate change, and other threats to seagrass habitats.

Seagrass meadows and sand dunes are lesser known coastal ecosystems that are located landward from coral reefs and sometimes seaward from mangroves. (At other times mangroves lie between seagrasses and sand dunes.) These ecosystems are also important for coastal communities because of the services they provide and are critical components of a vital, interdependent and interconnected series of coastal ecosystems.
