Data for bihourly brooding patterns models

Data table for linear mixed models (LMMs) examining whether nestling-stage temperature and nest characteristics predicted bihourly brooding patterns (Tables 1 & 2 of published article). Column headings: Year: year of nest construction; Plot: low, mid, or high elevation study plot; Female: unique female identifier; Nest: unique nest identifier; Window: identity of 2-h window over which measurements were averaged; Elevation: elevation of nest site in m; MeanOffboutDuration: mean brooding off-bout duration in s over 2-h window; OffboutFrequency: brooding off-bout frequency per h over 2-h window; PercentTimeOff: proportion of time female was off the nest over 2-h window; MeanAmbTemp: mean temperature in degrees C recorded over 2-h window; BroodSize: mean number of nestlings in the nest over days 3-5 of the nestling stage; Fledge: whether nest fledged young (1) or not (0); Hatch: date nestlings hatched; JDHatch: Julian date that nestlings hatched. Data were collected from a breeding population of the migratory Black-throated Blue Warbler at the Hubbard Brook Experimental Forest (HBEF), Woodstock, New Hampshire, USA (43.93N, 71.75W), from 2010-2013.

本数据集为用于检验雏鸟阶段温度与巢特征能否预测双小时育雏模式的线性混合模型（linear mixed models, LMMs）数据表，对应已发表论文中的表1与表2。列名说明如下：Year：筑巢年份；Plot：研究样地的海拔梯度，分为低、中、高海拔样地；Female：雌性个体唯一标识号；Nest：鸟巢唯一标识号；Window：用于计算平均测量值的2小时时段编号；Elevation：巢位海拔高度，单位为米（m）；MeanOffboutDuration：2小时时段内平均离巢时长，单位为秒（s）；OffboutFrequency：2小时时段内每小时离巢频次；PercentTimeOff：2小时时段内雌性离巢时间占比；MeanAmbTemp：2小时时段内平均气温，单位为摄氏度（℃）；BroodSize：雏鸟阶段第3至5天时巢内平均雏鸟数量；Fledge：雏鸟是否成功离巢，成功记为1，失败记为0；Hatch：雏鸟孵化日期；JDHatch：雏鸟孵化的儒略日（Julian date）。本数据集采集自美国新罕布什尔州伍德斯托克市哈伯德布鲁克实验林（Hubbard Brook Experimental Forest, HBEF，坐标43.93N, 71.75W）内的迁徙性黑喉蓝林莺（Black-throated Blue Warbler）繁殖种群，采集时段为2010年至2013年。
