Models evaluating the patterns of community diversity (Shannon’s entropy and Simpson’s evenness) and food-web structure (connectance, linkage density, nestedness) in relation to environmental variables and their interactions.

IR = %incident radiation, WV = water volume (mL), FPOM = fine particulate organic matter (mL), PPR = Predator:Prey Ratio (see text). Only variables and interactions with pIR为入射辐射（incident radiation），WV为水体体积（water volume，mL），FPOM为细颗粒有机物（fine particulate organic matter，mL），PPR为捕食者-猎物比（Predator:Prey Ratio，详见正文）。仅纳入变量及其与p相关的交互项。
