Arctodiaptomus salinus inhabits water bodies across Eurasia and North Africa. Based on our own data and that from the literature, we analyzed the influences of several factors on the intra- and inter-population variability of this species. A strong negative linear correlation between temperature and average body size in the Crimean and African populations was found, in which the parameters might be influenced by salinity. Meanwhile, a significant negative correlation between female body size and the altitude of habitats was found by comparing body size in populations from different regions. Individuals from environments with highly varying abiotic parameters, e.g. temporary reservoirs, had a larger body size than individuals from permanent water bodies. The changes in average body mass in populations were at 11.4 times, whereas, those in individual metabolic activities were at 6.2 times. Moreover, two size groups of A. salinus in the Crimean and the Siberian lakes were observed. The ratio of female length to male length fluctuated between 1.02 and 1.30. The average size of A. salinus in populations and its variations were determined by both genetic and environmental factors. However, the parities of these factors were unequal in either spatial or temporal scales.
盐沼北极镖水蚤栖息于欧亚大陆和北非的水体中。基于我们自己的数据以及文献中的数据，我们分析了几个因素对该物种种群内和种群间变异性的影响。在克里米亚和非洲种群中，发现温度与平均体型之间存在强烈的负线性相关，其中这些参数可能受盐度影响。同时，通过比较不同地区种群的体型，发现雌性体型与栖息地海拔之间存在显著的负相关。来自非生物参数变化很大的环境（如临时性水库）的个体，比来自永久性水体的个体体型更大。种群中平均体重的变化为11.4倍，而个体代谢活动的变化为6.2倍。此外，在克里米亚和西伯利亚湖泊中观察到了盐沼北极镖水蚤的两个体型组。雌性体长与雄性体长的比例在1.02至1.30之间波动。盐沼北极镖水蚤种群的平均体型及其变化是由遗传和环境因素共同决定的。然而，这些因素在空间或时间尺度上的重要性并不相等。
