Life-history dependent relationships between plasma alkaline phosphatase activity and body condition in male Eurasian Tree Sparrows

Table 1 Statistical results of best fitted regression models of plasma alkaline phosphatase (ALP) activity against life-history stage (stage, dummy variable) and body mass (Mass), size-corrected mass (SCM), or hematocrit (Hct) and their interactions in male Eurasian Tree Sparrows (Passer montanus) from the breeding and the wintering stages
