Ground pearl (genus Margarodes), any of a group of scale insects in the family Margarodidae (order Homoptera) that have an iridescent globular body 2 to 4 mm (0.08 to 0.16 inch) in length.
One striking example of an evolved asymmetry in vertebrates comes from a group of scale-eating cichlid fishes from Lake Tanganyika.
It has been considered to be a stem group of scale insects (Hodgson and Hardy, 2013, Figure 3) or a group within Ortheziidae (Vea and Grimaldi, 2015, Figure 24).
Second-order confirmatory factorial analysis was used to verify the grouping of scales of the CPCI into two major coping families.
The analysis of the catalogues of measures involved four steps: counting occurrences and co-occurrences, normalizing and averaging, scaling, and grouping of scaled values.
However, both factors are absent in the evolutionary history of basal groups of scale insects.
This is typical of a multivariate normal distribution with a common scale parameter (or different groups of scale parameters) and a large number (say a few hundreds or thousands) of location parameters.
For example, most SNPs with values in the first group of informative scales for FST also fell into the first group of δ, with a few falling into the 2nd group of δ.
These virtues all apply to a group of modestly scaled exhibitions in and around Boston this summer.
Architecture trumps nature in a fascinating group of large-scale works installed in the main gallery.
