Wetlands have important filter functions in landscapes but are considered to be the biggest unknowns regarding their element dynamics under global climate change.
The derivation is based on the extended Hamilton's principle and includes the effect of initial geometric imperfections (axial, curvature, and twist) on the line element dynamics.
Interspecific comparisons of overall repetitive sequence content and TE composition [1], [18] and of INE-1 element dynamics [19] in the 12 genomes do not support this explanation.
Little is known about the relationships between genome polymorphism, mobile element dynamics, and population size among animal populations.
Overall, the patterns of rearrangements may be explained by the combined influences of recombination (i.e., most likely nonhomologous and intrachromosomal), accumulated repeats, especially at intergenic regions, and to a lesser extent, mobile element dynamics.
However, Helfrich et al. note that PARIHS would be strengthened if one could describe how contextual element dynamics emerge and whether or not there are some generalizable interactional patterns [ 9].
Deciphering the complex relationship between transposable element dynamics and mode of reproduction is further complicated by events of hybridization (intra- or inter-specific) involving apomicts in diploid-polyploid-dihaploid cycles [ 10].
The mtDNA comparative analyses between close relatives of Rhizophagus spp. shows that dpo-like sequences and SIR-mediated recombinations not only enhance mtDNA reshuffling but could also lead to fragmentation, impacting mobile element dynamics in mt genomes.
Natural H. annuus × H. petiolaris hybrid populations likely served as original source populations from which the three hybrid species lineages became established and, as such, represent excellent natural laboratories for investigating the direct role of hybridization on transposable element dynamics in this group.
