Results from a generalized linear mixed model relating richness at 373 sites (number of species observed, Poisson response) to the reserve status of sites (reserved or not, fixed effect) and the ecoregion of sites (random effects).

本研究结果来自一项广义线性混合模型（generalized linear mixed model）分析，该模型以373个调查样点的物种丰富度（即观测到的物种总数，为泊松分布响应变量）为因变量，以样点保护状态（分为受保护与未受保护，属固定效应）以及样点所属生态区（属随机效应）作为解释变量。
