Chorus frog density and population growth, Cameron Pass, Colorado, 1986-2020

We investigated population dynamics in chorus frogs (Pseudacris maculata) relative to extrinsic (air temperatures and snowpack) and intrinsic (density dependence) characteristics at 2 sites in Colorado, USA. We used capture-mark-recapture (cmr) data (i.e., 1 or 0, provided here) and a Bayesian model framework to assess our a priori hypotheses about interactions among covariates and chorus frog survival and population growth rates. Files include: Cameron_Lily_cmr_NOV2020.csv, Cameron_Matthews_cmr_NOV2020.csv, and Cameron_covariates_NOV2020.csv. Data associated with paper by Kissel et al. 2021.

我们针对美国科罗拉多州的2个监测样点，开展了斑拟树蟾（Pseudacris maculata）的种群动态研究，重点解析其种群动态与外在因子（气温与积雪量）及内在因子（密度制约，density dependence）的关联。本研究采用标记重捕法（capture-mark-recapture, CMR）数据（本次提供的数据以1或0表示），结合贝叶斯模型框架，对协变量（covariates）间的交互作用以及斑拟树蟾存活率与种群增长率的先验假说进行评估。本数据集包含以下文件：Cameron_Lily_cmr_NOV2020.csv、Cameron_Matthews_cmr_NOV2020.csv及Cameron_covariates_NOV2020.csv。本数据集关联Kissel等人2021年发表的研究论文。
