The study of fluctuating asymmetry (FA) in living organisms has produced contradictory results over 22 the past few decades of research. Though the protocol for measuring FA is firmly established, the 23 sources of FA remain unclear in many cases. Our goal is to examine the relationship between FA 24 and both the concentration of biomarkers of reactive oxygen species (ROS) and body condition in a 25 medium-sized mammal, the European wild boar (Sus scrofa). Using a Partial Least Squares 26 regression (PLSr), we found a positive significant relationship (Stone-Geisser test) between 27 oxidative stress and FA but a negative relationship between oxidative stress and body condition. Our 28 results suggest that FA can be used to assess the physiological costs associated with oxidative 29 stress in mammals. 30

“…Достаточно большое число работ посвящено изучению ФА у различных живот-ных: повышение ФА может наблюдаться на фазе пика численности у животных [9]; стрес-сирующего воздействия различного характера [10][11][12][13][14][15]. Известно, что уровень флуктуирующей асимметрии у рыб, лягушек, а также водных и околоводных млекопитающих возрастает при повышении загрязнения водоема [15][16][17].…”

“…However, disruption of cellular processes (Cánovas et al . ) can result in developmental instability and deviations from perfect symmetry termed fluctuating asymmetry (FA). Fluctuating asymmetry has been correlated with a variety of environmental and genetic stressors in a variety of taxa (Zakharov et al .…”

“…, Cánovas et al . ), including pinnipeds, and promoted as an easily monitored indicator of stress providing an early warning of adverse conditions. However, FA has also failed as a biomarker of stress in some species in certain circumstances (Schandorff , Lens et al .…”

Low temperatures during ontogeny increase fluctuating asymmetry and reduce maternal aggression in the house mouse, Mus musculus

“…(Canovas et al., ; Graham et al, ; Clarke & McKenzie, ). For example, perinatal oxidative, audiogenic, and cold stress (Siegel & Doyle, ,b,c; Siegel, Doyle, & Kelley, ; Sciulli, Doyle, Kelley, Siegel, & Siegel, ; Mooney, Siegel, & Gest, ; Gest, Siegel, & Anistranski, ; Canovas et al., ; Breno, Bots, De Schaepdrijver, & Van Dongen, ), inbreeding, (Mather, ; Thoday, ), or harmful mutations (McKenzie & Clarke, ) elevate FA in the offspring. Also, exposure to chemical pollution (Ames, Felley, & Smith, ; Hoffman & Parsons, ; Valentine, Soulé, & Samollow, ), temperature extremes (Gest et al., ; Mooney et al., ; Siegel & Doyle, ,b,c), and high population density (Zakharov, Pankakoski, Sheftel, Peltonen, & Hanski, ) yield high FA.…”

“…Deviations from perfect symmetry may thus reflect how individual organisms have coped with developmental stress. (Canovas et al, 2015;Graham et al, 2010;Clarke & McKenzie, 1992). For example, perinatal oxidative, audiogenic, and cold stress (Siegel & Doyle, 1975a,b,c;Sciulli, Doyle, Kelley, Siegel, & Siegel, 1979;Mooney, Siegel, & Gest, 1985;Gest, Siegel, & Anistranski, 1986;Canovas et al, 2015;Breno, Bots, De Schaepdrijver, & Van Dongen, 2013), inbreeding, (Mather, 1953;Thoday, 1958), or harmful mutations (McKenzie & Clarke, 1988) elevate FA in the offspring.…”
