“…The three markers are also in agreement in demonstrating the influence of the physiographic features of the sampling sites in the clustering of groups. The agreement between physiographic features and species differentiation has already been reported by other studies using mtDNA and Population analysis of Mourella caerulea geometric morphometrics of wings (Francisco et al 2008;Francoy et al 2011Francoy et al , 2016Combey et al 2013;Bonatti et al 2014;Lima et al 2014;Hurtado-Burillo et al 2016). This influence may be due to some environmental effects on the heritability of the patterns of wing venation, which can vary between different parts of the wings (Monteiro et al 2002).…”

To characterize the populational diversity of Mourella caerulea , an endemic stingless bee from the Pampa biome, we collected workers of the stingless bee Mourella caerulea from 24 colonies of five localities in Southern Brazil and analyzed it using geometric morphometrics of forewings, mtDNA cytochrome oxidase I variability, and cuticular hydrocarbon (CHC) chemical analysis. The morphometric analysis discriminated the populations of M. caerulea from different physiographic regions. There was a positive correlation between morphometric and geographic distances. CHC profiles also differentiated the colonies from different localities. We found six particular haplotypes, nucleotide diversity (π) of 0.01631, and a haplotype diversity (Hd) of 0.74. In this sense, the comparison of the population belonging to different physiographic regions indicates that we need to give particular attention to M. caerulea at the moment of creating conservation strategies for South Brazilian Fauna, once it is the only species of this monospecific genus, and its populations are much differentiated from each other. stingless bees / Mourella caerulea / geometric morphometrics / mitochondrial DNA / cuticular hydrocarbons Electronic supplementary material The online version of this article (

“…reduced genetic variation). Moreover, previous reports have shown that fore wing size and shape of some Melipona species are influenced by both geographic distance and altitude, like that observed in M. scutellaris Latreille (Nunes et al 2007), M. quadrifasciata anthidioides Lepeletier (Nunes et al 2013) and M. subnitida Duke (Lima et al 2014). Nonetheless, no significant morphometric differences were observed in M. mandacaia in relation to altitude (p>0.05), but both fore wing size and shape were correlated to geographic distance (p<0.001 and p<0.05, respectively).…”

Melipona mandacaia is a stingless bee species responsible for the pollination of many native plants in Brazil, South America. In spite of its ecological and economic importance, natural populations of M. mandacaia have been depleted because of deforestation. In order to evaluate the interpopulation morphometric structure of remaining populations, we carried out geometric morphometric studies based on fore wing shape in this native bee species. The grouping analysis by UPGMA revealed three distinct clusters and significant differences in fore wing size were observed (p<0.001) among populations. The three groups were also reflected in the first two principal components explaining about 60% of the total variation. These results indicate differentiation among populations, which can be regarded as unique management units. Therefore, efforts should be directed to the conservation of local populations of M. mandacaia to avoid the negative impacts of loss in pollination over plant species and environmental services.

“…It has been demonstrated that geographical distance can be correlated to wing shape variability, e.g., in Drosophila [ 59 ], Lepidoptera [ 60 ] and Melipona [ 61 ]. Yet, in the present study, we do not identify such correlation on the broad West Palearctic range of the three Melitta species.…”

Distribution and predictors of wing shape and size variability in three sister species of solitary bees

et al. 2017

Morphological traits can be highly variable over time in a particular geographical area. Different selective pressures shape those traits, which is crucial in evolutionary biology. Among these traits, insect wing morphometry has already been widely used to describe phenotypic variability at the inter-specific level. On the contrary, fewer studies have focused on intra-specific wing morphometric variability. Yet, such investigations are relevant to study potential convergences of variation that could highlight micro-evolutionary processes. The recent sampling and sequencing of three solitary bees of the genus Melitta across their entire species range provides an excellent opportunity to jointly analyse genetic and morphometric variability. In the present study, we first aim to analyse the spatial distribution of the wing shape and centroid size (used as a proxy for body size) variability. Secondly, we aim to test different potential predictors of this variability at both the intra- and inter-population levels, which includes genetic variability, but also geographic locations and distances, elevation, annual mean temperature and precipitation. The comparison of spatial distribution of intra-population morphometric diversity does not reveal any convergent pattern between species, thus undermining the assumption of a potential local and selective adaptation at the population level. Regarding intra-specific wing shape differentiation, our results reveal that some tested predictors, such as geographic and genetic distances, are associated with a significant correlation for some species. However, none of these predictors are systematically identified for the three species as an important factor that could explain the intra-specific morphometric variability. As a conclusion, for the three solitary bee species and at the scale of this study, our results clearly tend to discard the assumption of the existence of a common pattern of intra-specific signal/structure within the intra-specific wing shape and body size variability.
