“…This study joins an increasing body of recent research on the role of fluctuating asymmetry in odonates (e.g. Córdoba‐Aguilar, 1995; Bonn et al 1996; Leung and Forbes 1997; Jennions 1998; Carchini et al 2000, 2001) and other insects (Thornhill 1992; Thornhill and Sauer 1992; Hunt and Simmons 1997, 1998; David et al 1998). Clearly the relationship between fluctuating asymmetry, reproductive success, and fitness needs additional exploration in insects.…”

We examined fluctuating asymmetry and morphology as they relate to reproductive success, territoriality, and relative survivorship in the dark‐winged damselfly Calopteryx maculata. Fluctuating asymmetry was not correlated with any aspect of morphology in males, but it did predict mating status in males. Mating males showed significantly lower levels of forewing asymmetry than did non‐mating males holding adjacent territories. While fluctuating asymmetry did not relate to survivorship or resource holding ability, body size did. Larger males were able to hold territories longer and lived longer than smaller individuals. We suggest that size is of greater importance in this species with regards to fitness and that fluctuating asymmetry may play a minor role by impacting short‐term mating success.

“…The most common measure of DS is fluctuating asymmetry (FA), the nondirectional deviation from bilateral symmetry (Van Valen 1962). Several studies have found evidence for increasing FA with inbreeding, using individuals or populations varying in heterozygosity (Leary et al 1983(Leary et al , 1984Alibert et al 1994) or comparisons of inbred lines with their F 1 hybrids (Mather 1953;Beardmore 1960;Reeve 1960), whereas others have failed to find such a relationship (heterozygosity: Clarke et al 1992;Gilligan et al 2000;Carchini et al 2001;controlled inbreeding experiments: Fowler and Whitlock 1994;Sheridan and Pomiankowski 1997;Hosken et al 2000). This inconsistency in the results has raised doubts about the generality of FA as an index of DS and about the reliability of FA to detect inbreeding effects (see reviews in Palmer and Strobeck 1986;Møller and Swaddle 1997;Vøllestad et al 1999;Gilligan et al 2000).…”

Inbreeding, the mating of close relatives, is known to have deleterious effects on fitness traits in organisms. Developmental stability (DS) and canalization may represent two processes that allow an organism to maintain a stable development that will produce the fittest phenotype. Inbreeding is thus expected to affect either DS or canalization. We tested if inbreeding affects DS and canalization using an inbreeding experiment on the cricket Gryllus firmus. We compared mean length, fluctuating asymmetry (as an index of DS), and morphological variation (as an index of canalization) of four limb traits between seven highly inbred lines, their F1 crosses, and outbred lines originated from the same stock population and maintained in the same environmental conditions. We show evidence for moderate inbreeding depression on the four measures of leg length. The nonsystematic difference in fluctuating asymmetry indices between breed types indicates that inbreeding or heterozygosity did not affect DS, or that fluctuating asymmetry is not a reliable index of DS. In contrast, inbreeding appears to affect canalization, as shown by the significantly higher variation in inbred lines compared to other lines. Identical low variation values in the crossbred and outbred lines indicate that heterozygosity could affect canalization. High variation in morphological variation and fluctuating asymmetry within crossbred or inbred lines, however, suggest the effect of recessive deleterious alleles on both canalization and DS. Although the strong correlation in morphological variation among traits suggests that identical genetic mechanisms govern canalization for all the limb traits, the absence of significant correlation in fluctuating asymmetry among traits causes us to reject this hypothesis for DS. For most of the traits, morphological variation and fluctuating asymmetry were not significantly correlated, which support the hypothesis that canalization and DS consist in two distinct mechanisms.

“…in damselflies (Carchini et al. ). Strong evidence supporting linkage between heterozygosity and body size comes from the studies on shell length of bivalves, as positive associations between both traits were demonstrated for several species, such as eastern oyster ( Crassostrea virginica Gmelin, 1791) (Zouros et al.…”

Positive effects of individual heterozygosity on naturally selected traits have been reported in wild populations of many animal taxa. The aim of this study was to test whether heterozygosity predicts the quality of acquired nest sites and productivity in a colonially breeding waterbird, the whiskered tern (Chlidonias hybrida). For this purpose, 40 adult terns from a small, recently established population in Central Poland were typed at eight microsatellite loci. We demonstrate that individual heterozygosity is positively related to hatching success. We hypothesize that this association could be mediated by direct effects of heterozygosity on the competitive abilities of individuals. We found that more heterozygous terns tended to breed in better protected central parts of the colony, suggesting that they had capabilities of outcompeting less heterozygous individuals and relegating them to the less attractive peripheries of the colony. It was also demonstrated that the link between heterozygosity and individual abilities to acquire more attractive nest site could be mediated by the larger size of heterozygous individuals. Although no correlations between heterozygosity and different components of condition were found, there was a positive association between female heterozygosity and both clutch size and egg size. We suggest that demonstrated heterozygosity‐fitness correlations could be primarily caused by inbreeding depression in the studied whiskered tern population.
