Abstract

Abstract:

Mangrove is one of the typical coastal wetland ecosystems. Studying its ecological stoichiometry characteristics is important to understand the nutrient utilization, distribution and environmental adaptation strategies of mangrove plants at different successional stages. In the present study, three typical mangrove species, Avicennia marina, Kandelia obovate, and Bruguiera gymnorrhiza were studied. The stoichiometry characteristics of carbon (C), nitrogen (N), and phosphorus (P) in different organs and the sedimental organic carbon (SOC), total nitrogen (TN), and total phosphorus (TP) in the sediments were measured and compared. The ecological stoichiometry characteristics of different organs and sediment nutrients in three intertidal zones of mangrove plants were also analyzed. The results showed that the C, N, and P contents of the three mangrove plants were higher in the leaves and stems than those in the roots(P<0.05). The N and P contents in the leaves and stems of A. marina were significantly higher than those of K. obovate and B. gymnorrhiza (P<0.05). Mangrove plants have unique adaptation strategies to habitats in the different intertidal zones. At the early stage of succession, the plants were distributed in low tide with a competitive strategy. At the advanced stage of succession, the plants were distributed in high tide and the strategy was changed to defense. Correlation analysis showed that the P content in the stems and roots of K. obovate was negatively correlated (P<0.05), while the N and P contents in the leaves and stems were positively correlated (P<0.05). The contents of N and P in the leaves and stems were negatively correlated with SOC, TP and C:N. It was also found that with the succession of mangrove communities from the sea towards the land, the limiting element for the mangrove plants growth has changed from N to both N and P.

Key words: mangrove plant, succession, adaptation strategy, ecological stoichiometry
