These forests are dependent upon the regular tides that flush leaves, twigs, and mangrove propagules out into the open ocean.

Knee roots are a type of horizontal root that periodically grow vertically and then, in a near hairpin loop, grow back downsimilar to the look of a bent knee. In 2006, two nearby archipelagos were washed away, an illustration that the threat of the entire forest vanishing beneath the ocean is a real concern. >> The stunted growth is often attributed to a lack of nutrients, high salinity, and rocky soils.

Dr. Feller and colleagues are finding that seedlings of all species at the northern limit of mangroves are super reproductive. /S /Transparency As the fish are eaten by predators, their energy and nutrients become another link in the chain. The primary producers in mangrove ecosystems are the mangroves themselves. These adaptations are so successful that some mangroves are able to grow in soils that reach salinities up to 75 parts per thousand (ppt), about two times the salinity of ocean water. << The biggest threat to mangroves is the emergence of shrimp farms, which have caused at least 35 percent of the overall loss of mangrove forests. /S /URI /Contents 53 0 R >> They raise the young in nurseries, taking turns caring for their own as well as others' offspring and protecting them fiercely. endobj endobj endobj >> They are also important because they provide a habitat for other species that live in the ecosystem, like fish and birds.
