“…In the earlier study (Zakharov et al 1991) we found that the level of developmental stability was negatively correlated with density in a cyclic population, but not in a noncyclic population. Comparison of the observed patterns of variation in total phenotypic diversity with those for developmental stability could provide us with information about what fraction of the temporal pattern of variation in total phenotypic diversity is due to variation in developmental stability, and whether this fraction differs between the two populations.…”

“…This variance of (1-r) is a good measure of developmental stability (Mather 1953, Thoday 1958, Zakharov 1981). When applied to populations of shrews, we showed (Zakharov et al 1991) that chance developmental variability, variance (1-r), mainly reflects the average condition of individuals within populations. Its annual values were positively correlated with annual estimates of density only in the cyclical Siberian population, while, as a non-specific measure of stress, it showed negative interaction with breeding success in both populations (Fig.…”

“…In the Siberian population, density is negatively correlated with breeding success, but these two parameters are not as closely correlated in the Finnish population. The data suggest, that in the Siberian population, overpopulation may adversely affect the condition of individuals, while in the Finnish population changes in environmental factors could be of primary importance (Zakharov et al 1991).…”

“…Details for trapping techniques, localities as well as for calculating the estimates of density and breeding success have been described earlier (Pankakoski 1985, Sheftel 1989, Zakharov et al 1991. The number of individuals studied was 254 for Siberia and 170 for southern Finland.…”

Developmental instability has been used to monitor the well-being of natural populations exposed to physical, chemical and biological stressors. Here, we use developmental instability to assess the impact of grazing on Chrysothamnus greenii and Seriphidium novum shrubs, and Oryzopsis hymenoides grass, common in the arid intermountain west of the U.S.A. Statistical noise in allometric relations was used as an indicator of developmental instability arising from grazing-induced stress. Unpalatable species that are not grazed (Chrysothamnus greenii) or species that are dormant during the winter-spring grazing period (Oryzopsis hymenoides) show lower allometric variability under high grazing pressure. Palatable species (Seriphidium novum) exhibit high developmental instability under low and high grazing pressure. Grazing pressure imposed by presumably co-adapted wild herbivores enhances developmental stability in species habituated to moderate grazing, like Oryzopsis hymenoides, but stresses plants such as Chrysothamnus greenii that prefer disturbed environments. These grazing effects are probably due to the impact grazing has on competitive relationships and not to the direct action of the herbivore on the plants.
