在大多数珊瑚礁上，在过去30年里，石珊瑚的覆盖率大大下降;一些对死亡更具抵抗力的物种受到的影响比其他物种小。滨珊瑚是一个物种，已成为整个加勒比海珊瑚礁社区的一个更突出的组成部分。对横跨加勒比海4 100公里弧形的6个地点的浅水（5至6米深）珊瑚礁进行了分析，以评估P. astreoides对当代珊瑚礁的贡献。利用2003/2004年记录的光样方估算了星叶松的盖度和种群密度，并分析了种群大小-频率结构，以了解种群的变化过程。在所有地点，珊瑚礁的特点是
On most coral reefs, the percentage cover of scleractinian corals has declined greatly over the last 30 yr; some species that are more resistant to mortality have been less affected than others. Porites astreoides is one species that has become a more prominent component of coral reef communities throughout the Caribbean. Analyses of coral reefs in shallow water (5 to 6 m depth) at 6 locations spanning a 4100 km arc of the Caribbean were used to evaluate the contribution of P. astreoides to contemporary reefs. Photoquadrats recorded in 2003/2004 were used to estimate the percentage cover and colony density of P. astreoides, and colony size-frequency structure was analyzed to gain insight into demographic processes. At all locations, reefs were characterized by
