Social stress impact on developmental stability of laboratory rat Rattus norvegicus

Developmental stability and canalization of limb bones of brown haresLepus europaeus with varying levels of heterozygosity

“…Also, an effect of heterozygosity on developmental stability and canalization might still exist, but could be concealed by the combined effect of much stronger environmental influences during bone growth, due to various exogenic factors, such as climatic or food stress, parasite load, environmental toxins or social stress (eg Siegel and Doyle 1975, Gest et al1986, Pankakoski et al 1992, Valetsky et al 1997, Lagesen and Folstad 1998. However, if a positive effect of heterozygosity on developmental homeostasis of limb bone length does exist, possible environmental stressors (acting in concert) should have a clearly stronger impact on the regular development.…”

Temporal and Spatial Variation in Metric Asymmetry in Skulls of Polar Bears (Ursus maritimus) from East Greenland and Svalbard

“…Many studies have been conducted in order to identify which forms of stress can affect FA and DS. Factors such as social stress (Valetsky et al 1997, Gibbs & Breuker 2006, inbreeding (Pertoldi et al 2000a), sexual selection (Voigt et al 2005), nutritional stress (Pravosudov & Kitaysky 2006), heat stress (Siegel et al 1977a, Petavy et al 2006, and disease and parasitic stress (Møller 2006) have been found to be positively correlated with levels of FA. Organic pollution is one form of environmental stress that has been another positively correlated with FA (e.g.…”

Inbreeding and outbreeding impact on developmental stability of laboratory rat Ratus norvegicus

“…The characters are described and defined in Fig. 1 in Valetsky et al 1997. No significant indications for the directional asymmetry or antisymmetry were registered for (1-r) distribution of these characters (Van Valen 1962, Palmer andStrobeck 1986).…”
