Effects of Reduced Light Availability on Carbon and Nitrogen Translocation in Posidonia sinuosa

The influence of shading on the translocation of carbon (C) and nitrogen (N) in Posidonia sinuosa plants was investigated from December 2004 to January 2005 in Cockburn Sound by measuring 13C and 15N isotopes in leaf material to determine whether changes in resource distribution may be a mechanism sustaining its growth during a period of light reduction.

本研究于2004年12月至2005年1月间在科克本湾（Cockburn Sound）开展，旨在探究遮光对波纹海神草（Posidonia sinuosa）植株体内碳（C）与氮（N）转运过程的影响。实验通过测定叶片材料中的碳13（13C）与氮15（15N）同位素丰度，以探明资源分配变化是否为植株在光照减弱阶段维持生长的潜在机制。
