Western Indian Ocean coral and fish local normalised species richness data, data collection period 1991 to 2019, depth 1 to 20 meters

Coral and fish species richness and environmental stress in ~300 georeferenced coral reef sites to evaluate local scale heterogeneity. Also include 21 specific environmental variables that were evaluated. Local coral and fish taxonomic richness were normalized to cover and biomass to partially account for human disturbances to coral cover and fish biomass. Field study sites were in 4 ecoregions and 8 countries that ranged in latitude from 2.04oS (Kenya) to 26.08oS (Mozambique) and longitudes of 32.96oE (Mozambique) to 57.71oE in (Mauritius)

本数据集包含约300个带地理坐标的珊瑚礁点位的珊瑚与鱼类物种丰富度及环境压力数据，用于评估局域尺度的生境异质性。同时，数据集纳入了21项经评估的具体环境变量。为部分抵消人类活动对珊瑚盖度及鱼类生物量的干扰，研究中将局域珊瑚与鱼类的分类学丰富度标准化至盖度与生物量维度。野外研究点位分布于8个国家的4个生态区，纬度跨度从南纬2.04°（肯尼亚）至南纬26.08°（莫桑比克），经度跨度从东经32.96°（莫桑比克）至东经57.71°（毛里求斯）。
