1 de ene. de 2009 · Molecular genetic data can be used to diagnose the status of populations and provide the management information. The loss of habitats and population degradation of the tri-spine horseshoe crab, Tachypleus tridentatus, in Asia urged the need to study patterns of phylogeography and population demography for its conservation.In this study, we first reviewed the marine reserves for T. tridentatus ...
4 de ago. de 2021 · The introduction of the polymerase chain reaction to phylogeography in the early 1980s, to both nuclear and mitochondrial genes, finally allowed direct visualization at the nucleotide level to the DNA changes underlying RFLPs; although phylogeographers still struggled then with the apparently low levels of variation detectable at nuclear genes and the challenge of recombination within loci, we ...
10 de feb. de 2016 · Genetic Divergences and haplotype networks All 46 samples yielded high-quality of DNA and were successfully sequenced for the mitochondrial COI and nuclear wingless (accession numbers KR911919 ...
24 de abr. de 2016 · Phylogeography is the discipline that analyzes the spatial arrangement of genetic lineages within and among closely related species. By focusing on gene trees of neutral loci from individuals in populations, phylogeographical analyses aim to understand the historical and contemporaneous forces that have produced the current genealogical architecture of populations and species [14, 15].
Phylogeography, Demographic History, and Reserves Network of Horseshoe Crab, ... Shanks et al. 2003), and whether reserve networks can exchange recruits with long dispersal (reviewed in Palumbi et al. 2003 and Palumbi 2004). The outcomes of ecological and genetic studies are providing information about species-level connections, ...
Phylogeography is a discipline concerned with various relationships between gene genealogies—phylogenetics—and geography. The word “phylogeography” was coined in 1987, and since then the scientific literature has reflected an exploding interest in the topic. Yet, to date, no book-length treatment of this emerging field has appeared. Phylogeography: The History and Formation of Species ...
23 de abr. de 2024 · Sequence variation, genetic diversity, and genetic structure. The lengths of the rps16 and ITS sequences obtained from 391 samples of A. trifoliata were 744 bp with a 33.9% G + C content and 695 bp with a 63% G + C content, respectively. We first identified a total of 22 rps16 haplotypes (C1 ∼ C22) and 75 ITS haplotypes (R1 ∼ R75) according to 59 and 88 polymorphic sites in the rps16 and ...
