Sentence examples for young taxa from inspiring English sources

By contrast, three genera contained a species pair or triad that lacked barcode divergence, cases that may reflect hybridization, young taxa or taxonomic over-splitting.

Price [ 3] demonstrated an inverse correlation between the divergence time of parental species and the width of avian hybrid zones, with young taxa typically having hybrid zones between 100 and 600 km wide.

Do more basal lineages have more restricted or wider distributions, compared to younger taxa?

In the genus Eleocharis, the observed C/n-values increase toward evolutionary younger taxa and show a highly significant phylogenetic signal (Table 1 Figure 1).

In addition, the density of Ty1- copia increases with evolutionarily younger taxa on the tree, whereas the density of Ty3- gypsy remains unchanged (dot blot) or slightly decreases (real-time PCR).

The cladocerans, Daphnia parvula Fordyce, 1901 and Daphnia retrocurva Forbes, 1882 (Fig. 1), provide an opportunity to study the role of ecological factors in promoting rapid divergence in potentially young lacustrine taxa with a mixed breeding system.

Additionally, our data suggests that after the divergence of the main mammalian taxa, young species-specific repeats (Alu of primates, B1 and B2 of rodents, etc).

This suggests that both processes affect the age distribution reported by Neiman et al. [ 17] differently in young versus old taxa, which contrasts Neiman et al.'s conclusion about the generality of underlying process.

Furthermore, both types of parental sequences of the nrITS region could be maintained, especially in the case in young hybrid-derived taxa that have had little opportunity for concerted evolution [ 57– 57].

In all taxa, younger age classes were characterized by significantly higher percent areas of fibro-lamellar and/or parallel-fibered tissues, while older age classes showed significantly higher proportions of lamellar bone.

Incomplete lineage sorting has often been recognized as a problem in resolving phylogenies of young and closely related taxa [ 68].
