Document Summary
Coastal wetlands are ecosystems that act as early warning devices for climate change. The environment has 3 layers: the substrate or the sediments, the vegetation, the animals. Adaptations of mangroves to the crabs and the second is when they release their young. Due to the sheer volume of the larvae, 90% of the larvae are left undisturbed by predator fishes. Losing saltmarshes at the expense of mangroves over the last 50 years. 30-40% of the saltmarshes are lost within the estuaries to mangroves. Happening also in the gulf of mexico, by. 2100 the whole region will be dominated by mangroves. Salt water has the effect of sapping fresh water. The theory is that there used to be major frosts from a plant (sodium toxicity) Mangroves ultrafilter the water and take out. 95% of the salt at the root system, almost freshwater. The remaining salt is excreted by the underside of the leaf.
