Many of those fish species feed other species that visit the mangroves, in turn supporting whole communities. Should a competing male enter a mudskippers territory, the two will engage in sparring competitions, their dorsal fins snapped erect as a warning.

They stabilize shores by trapping sediments and building land. Taking advantage of this demand, low-income workers in countries like Thailand flooded to the coasts in the 1980s and 1990s where work on shrimp farms was promised, and worthless mangrove forests were cleared to make space for shrimp pools. During past changes in sea level, mangroves were able to move further inland, but in many places human development is now a barrier that limits how far a mangrove forest can migrate. With only about 80 species of true mangrove trees worldwide, mangrove ecosystems comprise a relatively low number of habitat-forming tree species, but a high diversity of decomposer, detritivorous and consumer species. >> << >> Through a series of impressive adaptationsincluding a filtration system that keeps out much of the salt and a complex root system that holds the mangrove upright in the shifting sediments where land and water meet. 30 0 obj /S /Transparency .
