在加勒比地区，前礁生境主要由Montastraea spp。拥有最高的生物多样性，支持最多的生态系统进程和服务。在这里，我们表明，这种物种丰富的栖息地的分布可以解释一个环境预测：波曝光。波曝光和Montastraea珊瑚礁的发生之间的关系进行了建模，使用逻辑回归的整个伯利兹堡礁，在该地区最大的和地形最复杂的系统之一的珊瑚礁。该模型能够正确预测Montastraea礁的出现，准确率为81%。与历史定性模式一致，Montastraea珊瑚礁的分布受到高暴露环境的限制。这种模式可能是由限制补充的高速率慢性沉积物冲刷造成的。伯利兹模型参数化所用的各种波浪暴露条件表明，该模型应可在加勒比区域大部分地区推广，成为传统生境测绘的一种快速和廉价的替代办法，并补充全球绘制珊瑚礁范围的努力。
In the Caribbean region, forereef habitats dominated by Montastraea spp. have the highest biodiversity and support the largest number of ecosystem processes and services. Here we show that the distribution of this species-rich habitat can be explained by one environmental predictor: wave exposure. The relationship between wave exposure and the occurrence of Montastraea reefs was modelled using logistic regression for reefs throughout the Belize Barrier Reef, one of the largest and most topographically complex systems in the region. The model was able to predict correctly the occurrence of Montastraea reefs with an accuracy of 81%. Consistent with historical qualitative patterns, the distribution of Montastraea reefs is constrained in environments of high exposure. This pattern is likely to be driven by high rates of chronic sediment scour that constrain recruitment. The wide range of wave exposure conditions used to parameterize the model in Belize suggest that it should be transferable throughout much of the Caribbean region, constituting a fast and inexpensive alternative to traditional habitat mapping and complementing global efforts to map reef extent.
