Abstract：
The degree of developmental stability of individuals and populations is most often estimated by their level of fluctuating asymmetry (FA) - the random deviations from perfect symmetry. In our previous work, we recorded high levels of FA (FAMI index: frequency of asymmetric manifestation of an individual) in Pelophylax ridibundus populations that inhabit biotopes at Sazliyka River, south Bulgaria with high levels of anthropogenic pollution (domestic sewage pollution). At the same time, in the biotopes located in the upper reaches of the river (less disrupted habitats), the populations showed low levels of FA. Currently, we present the results of the study of the values of several morphological parameters: snout-vent length (SVL), body weight (BW), and body condition factor (CF) in the same populations of P. ridibundus. In addition, we evaluate the correlation between the values of these morphological parameters and the values of fluctuating asymmetry (the FAMI index), using the Kendall rank correlation analysis. The analysis of the relationships between the parameters characterizing the physical fitness of frogs and the indicator of developmental stability - the FAMI index - did not establish statistically significant correlations in the analyses in the whole groups of P. ridibundus from each site and in the correlations between sexes. We believe that the approaches to the study of developmental stability (analysis of fluctuating asymmetry levels) and those related to the assessment of physical fitness (health status) of frogs should be applied independently of each other.
摘要：
个体和群体的发育稳定程度通常是通过其波动不对称（FA）的水平来估计的，即与完美对称的随机偏差。在我们之前的工作中,我们记录了居住在萨兹利卡河生物群落中的Pelophylaxridibundus种群的高水平FA（FAMI指数：个体不对称表现的频率），保加利亚南部人为污染水平很高（生活污水污染）。同时,在位于河流上游的生物群落中（较少破坏的栖息地），人群的FA水平较低。目前,我们介绍了几个形态参数值的研究结果：鼻口长度（SVL），体重(BW),和相同种群的身体条件因子(CF)。此外,我们评估这些形态参数值与波动不对称性（FAMI指数）值之间的相关性，使用Kendall秩相关分析。对表征青蛙身体素质的参数与发育稳定性指标之间的关系的分析-FAMI指数-在每个地点的整个P.ridibundus组的分析中以及性别之间的相关性中，没有建立统计学上的显着相关性。我们认为，研究发展稳定性的方法（分析波动的不对称水平）以及与评估青蛙的身体素质（健康状况）有关的方法应相互独立应用。
