近年来，越来越多的研究都集中在野生动物的健康相关的生化和血液学参数的变化范围，但信息仍然是稀缺的酶的活动，这可能是非常重要的检测潜在的响应环境变化。在一个伟大的山雀（Parus major）种群中，我们描述了与年龄、性别、季节和年份有关的以下变化：（1）形态学：身体状况指数、脂肪和肌肉，（2）血液学：红细胞压积、血红蛋白、白色血细胞计数和嗜异性细胞/淋巴细胞比率，以及（3）生化参数：血浆蛋白和血浆胆碱酯酶（乙酰胆碱酯酶和丁酰胆碱酯酶）活性和红细胞谷胱甘肽过氧化物酶活性。性别对除脂肪外的所有形态参数均有显著影响。年龄显着影响胆碱酯酶活性，H/L比值和血红蛋白，有一个显着的性别和年龄之间的相互作用影响红细胞压积。有显着的年度和季节的相互作用，影响几乎所有的参数研究身体状况指数，脂肪，蛋白质，乙酰和丁酰胆碱酯酶的活动，谷胱甘肽过氧化物酶的活性和血红蛋白。本研究表明，这些参数在很大程度上影响的年度和季节效应，除了个人的内在变化。因此，在评价实验或环境变化效应时，应使用适当的对照。
In recent years, an increasing number of studies have focused on the ranges of variation of health related biochemical and haematological parameters in wildlife, but information is still scarce for enzymatic activities which can be extremely important in detecting potential responses to environmental change. In a Great Tit (Parus major) population, we describe the variation in relation to age, sex, season and year of: (1) morphological: body condition index, fat and muscle, (2) haematological: hematocrit, haemoglobin, white blood cell count and heterophil/lymphocyte ratio, and (3) biochemical parameters: plasma protein and activities of plasma cholinesterases (acetylcholinesterase and butyrylcholinesterase) activity and red blood cell glutathione peroxidase. Sex had significant effects on all morphological parameters except fat. Age significantly affected cholinesterase activities, H/L ratio and haemoglobin, and there was a significant interaction between sex and age affecting hematocrit. There were significant interactions of year and season affecting almost all parameters studied—body condition index, fat, protein, acetyl and butyrylcholinesterase activities, glutathione peroxidase activity and haemoglobin. This study indicates that these parameters are largely influenced by year and seasonal effects, besides the individual’s intrinsic variation. Therefore, when evaluating experimental or environmental change effects, appropriate controls should be used.
