单生珊瑚B的特定大小的死亡率和生长率。根据天然和人工基质中活珊瑚的大小频率分布以及在碎石通道中发现的死珊瑚的骨骼确定了秀丽珊瑚。标记样方进行监测，以衡量实际招聘和死亡率的青少年和成年人。青少年的第一年死亡率很高，为56%;成年人的死亡率约为每年10%。估计每年的幼虫存活率（44%）被纳入生命表，并计算其他人口参数。B。线虫具有高的内在增长率，这显然是因为高的幼虫存活率和较早的繁殖开始。人口增长部分受到高少年和随机成年死亡率的抑制。估计B的平均寿命为6-11年。在加州太平洋格罗夫的霍普金斯海洋生物保护区。
Size-specific mortality rates and growth rates for the solitary coral, B. elegans, are determined from size frequency distributions of live corals from natural and artificial substrates, and from skeletons of dead corals found in rubble channels. Marked quadrats were monitored to measure actual recruitment and mortality for juveniles and adults. First-year rate of mortality for juveniles is high, 56%; and mortality rate for adults is about 10% annually. Estimates of annual larval survivorship (44%) are incorporated in a life table, and other demographic parameters are calculated. B. elegans has a high intrinsic rate of increase apparently because of high larval survivorship and early onset of reproduction. Population growth is checked partly by high juvenile and random adult mortality. A 6-11 yr average life span was estimated for B. elegans at the Hopkins Marine Life Refuge in Pacific Grove, California.
