In 1991, a powerful cyclonic storm made landfall in an area of Bangladesh where the mangroves had been stripped away. >> The excavated mud includes nutrients from decaying matter from deep underground, and the burrows aerate the soil which, in turn, increases water drainage. endobj /GS7 46 0 R /S /Transparency 19 0 obj /Type /Catalog /F4 51 0 R Monkeys, birds, insects, and other plants all live in mangrove branches. /F1 48 0 R Official websites use .gov As the salty water evaporates, noticeable salt crystals often form on the surface of the leaves. The rise of shrimp farming is a response to the increasing appetite for shrimp in the United States, Europe, Japan and China in recent decades. As the trees grow they take the carbon from carbon dioxide and use it as the building blocks for their leaves, roots and branches. The mounds are also excellent hideouts and homes for other creatures like snakes. In the 1950s, coastal villages in the Indo-Pacific had an average of 5 miles of mangrove forest between themselves and the ocean.

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. /Border [0 0 0] In general, this is an area between latitudes of 25 degrees north and 25 degrees south, however, geographical limits are highly variable depending upon the area of the world and local climates. In places where freshwater streams meet the salty ocean, there are masses of trees called mangroves wading into the water. /Footer /Sect The mangrove trees often glow as though strung with Christmas tree lights.

The problem is that this approach doesnt work very well. So, the energy that enters an ecosystem as sunlight eventually flows out of the ecosystem in the form of heat. The bats, mostly concerned with just getting a sweet meal, are unknowingly helping the mangroves by pollinating their flowers.

As the plants develop into trees, they become more tolerant of cold temperatures and are better able to withstand periodic freeze events during the winter. The primary producers in mangrove ecosystems would not be able to do their job without decomposers providing nutrients for them. They protect the climate by absorbing carbon dioxide and reducing the amount of greenhouse gases in the atmosphere. /Tabs /S The pneumatophores of Sonneratia species can reach up to 10 feet (3 meters) in height, taller than a grown man. 22 0 obj >> Medicinal properties from mangroves include relieving pain, decreasing inflammation, treating diabetes, acting as an antitumor drug, ridding the body of parasites, as an antiseptic, and many, many more. These wetlands are often found in estuaries, where fresh water meets salt water and are infamous for their impenetrable maze of woody vegetation. >> Then, they constructed a slight slope leading down into the ocean so that tides could easily flow. 12 [153 0 R 153 0 R 153 0 R 153 0 R 153 0 R 153 0 R 153 0 R 153 0 R 153 0 R 153 0 R In a city of underground burrows, territoriality is the rule of life for fiddler crabs.
