Rocky reef multi-trophic level fisheries model: Hysteresis FL x FU- No Size Structure

R script to run simulations testing for hysteresis across levels of lobster and urchin fishing, attack rates of predators on urchins are all equal (ie, no size-structured predation)本R脚本用于开展模拟实验，以检验不同捕捞强度下龙虾与海胆捕捞的滞后效应；实验中所有捕食者对海胆的攻击率均相等，即不存在体型结构化捕食（size-structured predation）。
