Egg Mass Counts from Foothill Yellow-Legged Frogs (Rana boylii) in California from 1992-2021

We compiled time series of egg mass counts (an index of adult female abundance) from Rana boylii populations in 36 focal streams and fit a Multiple Population Viability Analysis (MPVA) model to quantify how streamflow metrics, stream temperature, and surrounding land cover affect population growth. In addition, data on streamflow, stream temperature, and surrounding land cover for each stream were compiled from existing sources.

本研究汇编了36条目标溪流中博伊尔蛙（Rana boylii）种群的卵团计数时间序列，该计数可作为成年雌性个体丰度的表征指标，并拟合多种群生存力分析（Multiple Population Viability Analysis，MPVA）模型，以量化水文指标、溪流水温及周边土地覆被对种群增长的影响。此外，各溪流的水文指标、溪流水温及周边土地覆被数据均从现有资料中汇编得到。
