Management options to minimise formation of urchin barrens: assessing dynamics of incipient urchin barrens patches in eastern Tasmania using timed swims

Timed GPS-tracked swims using SCUBA (45 and 30 minutes), were used to assess the changes in frequency and size of Centrostephanus rodgerii incipient barrens in eastern Tasmania. The number of C. rodgerii and Heliocidaris erythrogramma in each incipient barren were also assessed.

本研究通过时长为45分钟与30分钟的水肺潜水（SCUBA）GPS追踪巡游实验，对塔斯马尼亚州东部罗氏长棘海胆（Centrostephanus rodgerii）初期海胆荒的发生频率与斑块尺度的变化展开评估，并统计了每一处初期海胆荒内罗氏长棘海胆（C. rodgerii）与赤海胆（Heliocidaris erythrogramma）的个体数量。
