Ecophysiology of three habitat-forming seaweeds across a depth and latitudinal gradient in southeastern Australia (2010-2012)

Seasonal patterns in the in situ ecophysiology of the common habitat-forming seaweeds Ecklonia radiata, Phyllospora comosa, and Macrocystis pyrifera were investigated at different latitudes and depths in southeastern Australia. Multiple performance indicators (photosynthetic characteristics, pigment content, chemical composition, stable isotopes, nucleic acids) were used to assess the ecophysiology of seaweeds near the northern and southern margins of their range, along a depth gradient (E. radiata only), over a two year period (September 2010 August 2012).

本研究针对澳大利亚东南部不同纬度与深度生境中的三种常见造生境海藻——辐射昆布（Ecklonia radiata）、叶囊藻（Phyllospora comosa）与巨藻（Macrocystis pyrifera）的原位生态生理学季节变化模式展开了调查。研究周期为2010年9月至2012年8月，共计两年；期间通过多项生理性能指标（光合特性、色素含量、化学成分、稳定同位素、核酸），对分布于其纬度分布范围南北边缘的海藻进行生态生理学评估，其中深度梯度分析仅针对辐射昆布开展。
