The Shift of Nutritional Value in Sediment with Depth;Benthic Ecology Approach(II)
|Issue Date: ||2011-06-28T07:02:30Z
|Abstract: ||Abstract:Near surface deposit feeders in the Chuwei Mangrove Forest intertidal mudflat of Taipei County, Taiwan, recruit, increase to great abundance in late winter and early spring, then decrease to a very low value after the summer. Can we related this change to nutritive value of the sediment? The organic content failed to explain the temporary variation in animal abundance. The sedimentary organic carbon and nitrogen and labile protein may provide some clues to the variations. The increase of protein value in the deep layer of the sediment suggests the downcore transport of sediment nutrients by the bioturbation. The profiles of labile protein and chlorophyll contents suggest the vertical distribution of benthic animals may be limited by sediment nutrients.|
