生态学的一个中心目标是解释地球上生物多样性的异质分布。随着对多样性损失预期的增长（1-5），这种理解对于有效的管理和保护也至关重要。尽管对生物多样性模式的解释仍然存在激烈的争论(5)，但它们通常被认为是依赖于尺度的（6,7）。在大的地理尺度上，生物地理学家认为物种丰富度的变化是由诸如面积、温度、环境稳定性和地质过程等因素引起的（5,7-14）。从这些大规模过程产生的物种池来看，群落生态学家认为，局部尺度的群落聚集是通过竞争、捕食、招募、干扰和移民等过程实现的（5-8,15,16）。在这里，我们分析了关于印度洋和太平洋珊瑚鱼物种形成和扩散的假设，并展示了从一个主要起源中心扩散如何同时解释物种丰富度和当地群落结构的大规模梯度。
A central aim of ecology is to explain the heterogeneous distribution of biodiversity on earth. As expectations of diversity loss grow(1-5), this understanding is also critical for effective management and conservation. Although explanations for biodiversity patterns are still a matter for intense debate(5), they have often been considered to be scale-dependent(6,7). At large geographical scales, biogeographers have suggested that variation in species richness results from factors such as area, temperature, environmental stability, and geological processes, among many others(5,7-14). From the species pools generated by these large-scale processes, community ecologists have suggested that local-scale assembly of communities is achieved through processes such as competition, predation, recruitment, disturbances and immigration(5-8,15,16). Here we analyse hypotheses on speciation and dispersal for reef fish from the Indian and Pacific oceans and show how dispersal from a major centre of origination can simultaneously account for both large-scale gradients in species richness and the structure of local communities.
