Capture history data for: Sub-seasonal correlation between growth and survival in three sympatric aquatic ectotherms

Animals experience seasonally changing conditions in temperate regions, thus population vital rates change seasonally. However, knowledge is lacking on patterns of seasonal correlation between growth and survival in sympatric ectotherms, and this knowledge gap limits our understanding of environmental change impacts on animal populations and communities. Here, we investigated sub-seasonal (2-month intervals) correlation between growth and survival in three stream fishes (bluehead chub Nocomis leptocephalus, creek chub Semotilus atromaculatus, and mottled sculpin Cottus bairdii) in South Carolina, USA, via a mark-recapture survey over 28 months. 
We found that the patterns of temporal correlation between growth and survival differed among the sympatric species. Growth increased and survival decreased with water temperature in two eurythermal species (bluehead chub and creek chub), resulting in a negative correlation between growth and survival. Growth peaked in sub-seasons with an interm...

在温带地区，动物面临着随季节动态变化的环境条件，因此种群关键生命率（population vital rates）也会呈现季节性波动。然而，目前学界对同域分布（sympatric）变温动物（ectotherms）的生长与存活间的季节性关联模式仍缺乏系统认知，这一知识缺口限制了我们对环境变化如何影响动物种群与群落的理解。本研究依托美国南卡罗来纳州为期28个月的标记重捕调查（mark-recapture survey），针对3种溪流鱼类——蓝头雅罗鱼（*Nocomis leptocephalus*）、溪雅罗鱼（*Semotilus atromaculatus*）与斑头杜父鱼（*Cottus bairdii*），探究了亚季节尺度（sub-seasonal，间隔2个月）下其生长与存活间的关联模式。
研究结果显示，3种同域分布鱼类的生长与存活间的时间关联模式存在显著种间差异。对于两种广温性（eurythermal）鱼类（蓝头雅罗鱼与溪雅罗鱼），其生长随水温升高而提升，存活则随水温升高而下降，最终导致生长与存活间呈现负相关关系。在部分亚季节尺度的时段中，个体生长达到峰值，其对应的……
