The concentrations of total organic carbon in mangrove waters were 1.28, 1.52 and 0.60 ppm in the Shira, Nuha and Nagura rivers, respectively. The concentration of inorganic nutrients were determined from those mangrove waters are sodium (Na^+), potassium (K^+), ammonium (NH^+_4), chlorine (Cl^-), fluorine (F^-), bromine (Br^-), nitrate (NO^-_3), phosphate (PO^-2_4) and sulfate (SO^-2_4). No satisfactory explanation was found for the high concentrations of sodium and chlorine. The mangrove sediments C/N ratios were 17.9, 12.8 and 25.2 in the Shira, Nuha and Nagura rivers, respectively. The C/N ratio of Nuha river sediment was lower than that of the Shira and Nagura river, indicating higher nutritional value because of many organic matters decomposed here. Sediments from three mangroves had a mean C/N ratio of 18.6, indicating lower C/N ratios could be a richer source of nitrogen, which is regular ingestion by sesarmid crabs. Significant differences (P<0.0001) were found among the TOC concentrations in mangrove waters and C/N ratios in mangrove sediments from these three sites.","subitem_description_type":"Other"},{"subitem_description":"紀要論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"琉球大学理学部"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"eng"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/13167"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"ISSN","subitem_1522646572813":"0286-9640"},{"subitem_1522646500366":"NCID","subitem_1522646572813":"AN00250774"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"ja","subitem_1522650091861":"琉球大学理学部紀要"},{"subitem_1522650068558":"en","subitem_1522650091861":"Bulletin of the College of Science.
