物种丰富度格局的解释是生态学中最重要的任务之一，目前的理论强调影响区域物种池大小的历史和地理因素与当地作用过程(如竞争排除、干扰、生产力和季节性)之间的相互作用，植物和主要消费者的当地物种丰富度或阿尔法多样性已被认为在低和中等生产力的生境中达到峰值，如果这是真的，对保护有重大意义。这里，我们相反地表明，新热带灵长类动物(白颈鹿)的本地丰富度受历史生物地理和生产力的影响，而不是受树种丰富度或季节性的影响。这一模式表明，对许多重要的初级消费者来说，植物生产力最高的栖息地也是最丰富的，我们进一步表明，更新世亚马逊雨林的碎片化如果发生的话，似乎对灵长类阿尔法物种丰富度的影响可以忽略不计。
The explanation of patterns in species richness ranks among the most important tasks of ecology, Current theories emphasize the interaction between historical and geographical factors affecting the size of the regional species pool and of locally acting processes such as competitive exclusion, disturbance, productivity, and seasonality, Local species richness, or alpha diversity, of plants and primary consumers has been claimed to peak in habitats of low and intermediate productivity, which, if true, has major implications for conservation, Here, by contrast, we show that local richness of Neotropical primates (platyrrhines) is influenced by both historical biogeography and productivity but not by tree species richness or seasonality, This pattern indicates that habitats with the highest plant productivity are also the richest for many important primary consumers, We show further that fragmentation of Amazonian rain forests in the Pleistocene, if it occurred, appears to have had a negligible influence on primate alpha species richness.
