The influence of reef structure on the patterns and processes of Ecklonia radiata (C. Agardh) kelp beds of Hamelin Bay, Western Australia

The physical variables of light, water motion, reef slope and water depth were measured on topographically simple and complex reefs. \n\nThese physical variables were linked to patterns in the distribution of algae over the two reef types using DISTLM, a multivariate regression model.\n\nSpecies richness and total biomass is compared between cleared sites and control sites. Also the ability of pre-existing juvenile sporophytes to survive change in conditions associated with removal of their canopy was measured and as well as the relationship between Ecklonia radiata canopy and its associated understorey on reefs on reefs with simple and complex topography.

本研究在地形简单与复杂的礁体上，测定了光照、水流运动、礁体坡度与水深四类物理变量。

借助多元回归模型DISTLM，将上述物理变量与两类礁体上的藻类分布格局进行关联分析。

本研究对清理样地与对照样地的物种丰富度及总生物量开展对比分析。此外，还测定了现存幼孢子体在因冠层移除导致的环境变化中的存活能力，并分析了地形简单与复杂礁体上，辐射囊叶藻（Ecklonia radiata）冠层与其伴生下层植被之间的关联关系。
