decomposers in mangrove ecosystem

Dwarf, or scrub, mangrove forests only attain canopy heights of less than 5 feet (1.5 meters) although they contain the same species as the other types of forest.

Xylocarpus granatum roots have horizontal plank roots that lengthen vertically to increase the area above ground. While most terrestrial plants use whats called a taproot to burrow deep into the ground for support, several mangrove species rely on sprawling cable roots that stay within a few centimeters of the soils surface for stability and access to oxygen. /Rotate 0 Pneumatophores, like these cone roots, help the tree gain access to oxygen even when the roots are partially submerged. /Rotate 0 >> >> /K [23 0 R] 210 0 R 211 0 R 212 0 R 213 0 R 214 0 R 215 0 R 216 0 R 217 0 R] 190 0 R 191 0 R 192 0 R 193 0 R 194 0 R 195 0 R 196 0 R 197 0 R 198 0 R 199 0 R The scientists make use of the extensive collections at the National Museum of Natural History as well as the facilities at several Smithsonian facilitiesoutside of Washington, D.C.including the Smithsonian Environmental Research Center in Maryland, and the Smithsonian Tropical Research Institute in Panama, and field stations along the Atlantic and Caribbean coasts in Florida, Belize, and Panama.
