The determinants of genetic diversity in butterflies [PDF]

open access: yesNature Communications, 2019
AbstractUnder the neutral theory, genetic diversity is expected to increase with population size. While comparative analyses have consistently failed to find strong relationships between census population size and genetic diversity, a recent study across animals identified a strong correlation between propagule size and genetic diversity, suggesting ...

Inverse relationship between genetic diversity and epigenetic complexity [PDF]

open access: yes, 2008
Early studies of molecular evolution revealed a correlation between genetic distance and time of species divergence. This observation provoked the molecular clock hypothesis and in turn the ‘Neutral Theory’, which however remains an ...

Genetic Diversity of Toscana Virus [PDF]

open access: yesEmerging Infectious Diseases, 2009
Distribution of Toscana virus (TOSV) is evolving with climate change, and pathogenicity may be higher in nonexposed populations outside areas of current prevalence (Mediterranean Basin). To characterize genetic diversity of TOSV, we determined the coding sequences of isolates from Spain and France.

Climatic niche and neutral genetic diversity of the six Iberian pine species: a retrospective and prospective view [PDF]

open access: yes, 2010
Quaternary climatic fluctuations have left contrasting historical footprints on the neutral genetic diversity patterns of existing populations of different tree species.

Nation Formation and Genetic Diversity [PDF]

open access: yesSSRN Electronic Journal, 2006
This paper presents a model of nation formation in which culturally heterogeneous agents vote on the optimal level of public spending. Larger nations benefit from increasing returns in the provision of public goods, but bear the costs of greater cultural heterogeneity. This tradeoff induces agents' preferences over different geographical configurations,

Chloroplast microsatellites: measures of genetic diversity and the effect of homoplasy [PDF]

open access: yes, 2005
Chloroplast microsatellites have been widely used in population genetic studies of conifers in recent years. However, their haplotype configurations suggest that they could have high levels of homoplasy, thus limiting the power of these molecular markers.

High Genetic Diversity and Low Differentiation of Michelia coriacea (Magnoliaceae), a Critically Endangered Endemic in Southeast Yunnan, China [PDF]

open access: yes, 2012
Michelia coriacea, a critically endangered tree, has a restricted and fragmented distribution in Southeast Yunnan Province, China. The genetic diversity, genetic structure and gene flow in the three extant populations of this species were detected by 10 ...

Genetic diversity and core subset selection in ex situ seed collections of the banana crop wild relative Musa balbisiana [PDF]

open access: yes, 2019
Crop wild relatives (CWRs) play a key role in crop breeding by providing beneficial trait characteristics for improvement of related crops. CWRs are more efficiently used in breeding if the plant material is genetically characterized, but the diversity ...

Levels of genetic polymorphism: marker loci versus quantitative traits [PDF]

open access: yes, 1998
Species are the units used to measure ecological diversity and alleles are the units of genetic diversity. Genetic variation within and among species has been documented most extensively using allozyme electrophoresis.

Diversity of HLA Class I and Class II blocks and conserved extended haplotypes in Lacandon Mayans. [PDF]

open access: yes, 2020
Here we studied HLA blocks and haplotypes in a group of 218 Lacandon Maya Native American using a high-resolution next generation sequencing (NGS) method.
