Growth increment data
收藏资源简介:
Growth increment measurements from ocean perch otoliths for each discrete monthly time period. These data are used in the univariate mixed modeling analysis for the response variable of Growth. IDCode: unique identifier for each fish. Age.years.cap: age of the fish in years at date of capture. Age.month.cap: age of the fish in months at date of capture. Month.code.cap: month code for the date of capture, e.g. 75 = Dec 1996. FishID: = IDCode. Growth: measured value of the growth increment for a discrete monthly time period (μm). Month: a code designating the specific month and year of each monthly resolved increment (i.e. 75 = Dec 1996, 76 = Jan 1997, etc.). Age: age when each monthly increment was formed (total months). fMonth = Month (as factor).
本数据集包含各离散月度时段下海洋鲈鱼(ocean perch)耳石(otoliths)的生长增量测量数据。此类数据可用于以生长量为响应变量的单变量混合模型分析。 IDCode:每条记录对应鱼类的唯一标识符。 Age.years.cap:捕获时刻鱼类的年龄(以年为单位)。 Age.month.cap:捕获时刻鱼类的年龄(以月为单位)。 Month.code.cap:捕获日期的月份编码,例如编码75代表1996年12月。 FishID:与IDCode完全等价。 Growth:离散月度时段内的生长增量测量值,单位为微米(μm)。 Month:用于标记每条月度分辨率生长增量对应具体年月的编码,例如75代表1996年12月,76代表1997年1月,依此类推。 Age:每条月度生长增量形成时鱼类的总月龄。 fMonth:以因子型变量形式表示的Month。
