“…We verified the relationship between the size of the measured organs and the FA value (Palmer and Strobeck, 1986). Hence, we calculated FA according to the equation: FA = (R -L), (Palmer and Strobeck, 1986), where R is the size measured on the right side and L is the size measured on the left side, for both the antennae and the tibiae (Grześ et al, 2015;Souza et al, 2018;Oliveira et al, 2020). We applied linear mixed models (LMMs) using the function lmer from the lme4 package, considering the treatments as the explanatory variables and individual identity (measurement error) and plant identity as the random variables (Palmer, 1994).…”

“…FA was not a good indicator of environmental stress in ants Lasius flavus (Fabricius) collected along a heavy metal gradient. Despite eye reduction, in relation to morphometry, there was no significant difference between the right and left sides (Grześ et al, 2015). In addition, studies conducted in laboratory conditions can detect more significant effects on the FA of the insects than the studies conducted in the field (Beasley et al, 2013).…”

“…On the other hand, there are reports in the literature that negate the occurrence of symmetry disorders caused by exposure to heavy metals, e.g. Lasius flavus (Grześ et al 2015 ), Formica pratensis (Rabitsch 1997 ), Chironomidae spp. (Arambourou et al 2012 ).…”

The aim of the present study was to determine the fluctuating asymmetry of the first pair of wings in females Polistes nimpha (Christ, 1791) living in an environment contaminated with heavy metals. The average concentration of Zn, Cd and Pb in the bodies of the insects varied depending on the distance from the source of contamination, reaching the highest values on the site closest to the source of contamination and the lowest at the most distant site. As a result of the morphometric analyses, significant differences were found in the asymmetry values of the first pair of wings depending on the level of Zn, Cd, Pb accumulated by the wasps. In the case of shape asymmetry, differences were found for all the effects studied (year of capture and site). Significant differences were also found in the size of wings between individuals captured on Sites 1 and 2 and those caught on Site 3. Specimens caught on site characterized by the lowest concentration of heavy metals in the topsoil, proved to be significantly larger than the insects collected on the other sites. There were no differences in the size of individuals between the different years of capture. Based on the results obtained by us, it can be assumed that the wings of P. nimpha females may become a useful object in studying the impact of environmental stress of Zn, Cd and Pb pollution on the symmetry of their wings.

“…Based on correlative studies, we found no association between average body size in mature or immature colonies of L. niger (Grześ et al 2015a, 2015b). Similarly, the asymmetry of the eyes of Lasius flavus was not associated with pollution, suggesting the ability of ants to maintain a stable and repetitive trajectory of eye development during the larval stage (Grześ et al 2015c). Comparing the studies of other authors, ants seem to be much less sensitive to pollution-induced morphological changes than carabids in metal-polluted sites (Maryański et al 2002; Łagisz 2008) as well as in urbanized areas (Weller and Ganzhorn 2004; Sukhodolskaya 2013).…”

The phenotypic diversity of ant workers plays a fundamental role in their biology. In this study, we asked if the body size variation of monomorphic workers of the ant Lasius niger (Formicidae) responds adaptively to metal pollution in a post-mining metal-polluted area. Nest samples of workers were collected along a pollution gradient to calculate the within-colony variance in body size (expressed as maximum head width, HW). The results showed that the body size variation of L. niger was unrelated to the pollution index but demonstrated considerable variation between colonies even within the same study site. We suggest that the differences in morphological diversity between the colonies of L. niger could be shaped by colony personality traits, i.e., by colony-specific foraging and/or the feeding efficiency of nursing workers. The study supports previous findings, showing that morphological traits in Lasius ants are weakly related to environmental metal pollution.
