The bacteria in mangroves are very important, acting as decomposers and breaking down organic matter making it is available to the food web. So, the energy that enters an ecosystem as sunlight eventually flows out of the ecosystem in the form of heat. As for their ability to evolve in the face of a major stressor, like sea level rise, genetic diversity is key for a species to adapt to change.

Mangrove trees can be distantly related and are grouped together for their shared characteristics rather than true genetic ties. The organisms in these groups all play a key role in contributing to a functioning ecosystem. As mangroves and seagrasses grow larger, they require more and more nutrients. /S /Transparency 33 0 obj 9 0 obj However, rising temperatures and sea level due to climate change are allowing mangroves to expand their ranges farther away from the equator and encroach on temperate wetlands, like salt marshes. /ProcSet [/PDF /Text /ImageB /ImageC /ImageI] , as indicated by a very low levels of genetic variability. /Type /Page >> An exotic antelope from Asia called the nilgai was released in Texas in the United States in the 1930s as hunting game and is now not only a nuisance for cattle ranchers, but it also eats mangrove leaves. In 1986, Robin Lewis began a restoration experiment in Florida that changed mangrove restoration success. In mangroves, the creatures feeding on plants are often fish, insects or even decomposers (not much feeds on mangroves directly). Mud lobsters excavate underground burrows that extend down to two meters deep. In the mangrove forests of the Ganges Delta in the Sundarban forest of India and Bangladesh, roughly 500 tigers call the intertidal home. 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. /F5 52 0 R /Length 593 210 0 R 211 0 R 212 0 R 213 0 R 214 0 R 215 0 R 216 0 R 217 0 R] Many of those fish species feed other species that visit the mangroves, in turn supporting whole communities. /Parent 3 0 R >> /ExtGState << A 2013 study found that 71 percent of the forest is experiencing 656 feet (200 meters) of coastline retreat per year, almost the length of two football fields. and scavengers.
