Mangroves in peril: unprecedented degradation rates of peri-urban mangroves in Kenya

Salt balance in mangroves.

The tidal zone of tropical seas is frequently lined with great mangrove forests, the dominating species of which belong to such genera as Rhizophora, Bruguiera, Sonneratia, and Avicennia. The outstanding feature of these plants is their adaptation to growing in seawater, and even though all do well in river estuaries they seldom penetrate inland beyond the direct action of ocean tides. A questi...

How Mangroves Salinize the Soil How Mangroves Salinize the Soil

A transient one-dimensional model of the vertical movement of water and salt in the mangrove root zone is investigated. This is an extension of a previous steady state model which assumed that the ability of the mangrove roots to take up water is uniformly distributed throughout the soil and that the root water uptake is reduced if there is nonzero salt concentration around the roots. We show h...

Nutrient Limitation in Central Red Sea Mangroves

As coastal plants that can survive in salt water, mangroves play an essential role in large marine ecosystems (LMEs). The Red Sea, where the growth of mangroves is stunted, is one of the least studied LMEs in the world. Mangroves along the Central Red Sea have characteristic heights of ∼2 m, suggesting nutrient limitation. We assessed the nutrient status of mangrove stands in the Central Red Se...
