The morphometric variation of topotypic B. siculus with a focus on sexual dimorphism has been recently studied by Lo Valvo & Giacalone [ 40] in 354 males and 312 females.
No general framework exists, however, that extends the existing concepts and methods for studying morphometric variation of symmetric structures and biological asymmetry to all types of symmetry.
As a first approach, this study evaluated wing morphometric variation on A. calderoni of 2 localities from western Colombia, Guadalajara de Buga and San Andrés de Tumaco.
Fibre cross-sectional area (CSA) obtained from lateral dimensional measurements should consider the specific cross-sectional shape of natural fibres and its wide lengthwise morphometric variations.
We concluded that this study of traits of wild Capsicum, provides useful information of morphometric variation between wild populations that will be of value for future decision processes involved in the management and preservation of germplasm and genetic resources.
Specifically, we characterize broad patterns of morphometric variation using multivariate analysis, evaluate the extent and phylogenetic distribution of cave-associated morphologies, and discuss evolutionary, developmental, and taxonomic implications.
Beyond the patterns of morphometric variation, we therefore attempted to question the developmental processes that might be at work in this intriguing differentiation.
Furthermore, an analysis of morphometric variation in T. speciosissima sensu lato [ 12] showed that what had been considered to be a single, geographically widespread species actually comprised two allopatric, edaphically differentiated taxa: T. speciosissima on sandstones of the Sydney Basin and T. aspera on the northern granites of the Gibraltar Range (New South Wales, Australia).
Most studies of sperm morphometric variation are done in species with internal fertilization, where sexual selection can be mediated by complex mating behavior and the environment of the female reproductive tract.
