Humankind is undermining a crucial natural ally in the battle against climate change through its activities in the world's oceans and marine ecosystems, such as seagrasses, salt marshes and coastal wetlands, according to the United Nations Environmental Programme (UNEP). ❋ Unknown (2009)

And seagrasses are especially sensitive to sediment since they need light for photosynthesis suspended sediments make the water less clear, reducing light penetrance. ❋ John F. Bruno (2011)
The health of Florida's economy is strongly tied to the health of its beaches, dunes, fish populations, coral reefs, mangroves, seagrasses, wetlands and other natural resources. ❋ Unknown (2009)
To the south in 34i, hypersaline Laguna Madre forms a unique ecosystem and supports greater expanses of seagrasses. ❋ Unknown (2009)
The dominant seagrasses are turtle grass Thalassia testudinum, manatee grass Syringodium filiforme and shoal grass Halodule wrightii. ❋ Unknown (2009)
However, in the sea (with the exception of coastal areas with seagrasses & seaweeds) the primary producers appear invisible because they microscopic and the organisms we see are high up in the food chain. ❋ Unknown (2009)
Red, green and brown algae are found attached to bits of shell buried in the mud or to the seagrasses themselves. ❋ Unknown (2008)
The seaweeds Caulerpa taxifolia and C. racemosa overgrow seagrasses, creating monocultures that have been described as biological deserts. ❋ Unknown (2008)
These estimates represent, when scaled to the estimated global cover of seagrasses, a contribution to marine primary production of 0.61015 g C yr-1, or about 1.13% of the total marine primary production. ❋ Unknown (2008)
In the intertidal and subtidal areas of Padilla Bay, there are vast underwater meadows of seagrasses. ❋ Unknown (2008)
Wastewater discharge and bottom trawling in the Mediterranean impacted native seagrasses, helping an invasive strain of the tropical algae Caulerpa taxifolia colonize more than 130 square kilometers of seafloor in six countries in less than 20 years. ❋ Unknown (2008)
Blue crabs have declined in abundance in recent decades, partly as a direct result of fishing, but also as an indirect consequence of loss of seagrasses that provide nursery habitat for young crabs. ❋ Unknown (2008)
Preservation and restoration of coastal mangroves, seagrasses, coastal wetlands and reef systems protect shorelines from the power of storms. ❋ Unknown (2008)
In underwater eelgrass meadows, tiny phytoplankton (microscopic plants) float in the water and grow on the surface of the mud and seagrasses. ❋ Unknown (2008)
Nevertheless, the GRoWI figure is still considered an underestimate, especially for the Neotropics and for certain wetland types (such as intermittently flooded inland wetlands, peatlands, artificial wetlands, seagrasses, and coastal flats) where data were incomplete or not readily accessible. ❋ Unknown (2008)
There are over 150 species of alga that live among the Northwestern Hawaiian Island reefs, including red, green, and brown algae as well as some seagrasses. ❋ Unknown (2008)
Hence, seagrasses are important components of the marine carbon cycle, being responsible for a significant fraction of the net CO2 uptake by marine biota. ❋ Unknown (2008)
Seagrasses colonized the sea, from terrestrial angiosperm ancestors, about 100 million years ago, which indicates a relatively early appearance of seagrasses in angiosperm evolution. ❋ Unknown (2008)
