Unraveling the Complexity of the Ne/Nc Ratio for Conservation of Large and Widespread Pelagic Fish Species: Current Status and Challenges

open access: yesEvolutionary Applications
Estimating and understanding the ratio between effective population size (Ne) and census population size (Nc) are pivotal in the conservation of large marine pelagic fish species, including bony fish such as tunas and cartilaginous fish such as sharks ...

Genetic diversity and conservation in Bromeliaceae based on SSR markers [PDF]

open access: yesGenetics and Molecular Biology
Bromeliaceae has been used as a model Neotropical group to study evolutionary and diversification processes. Moreover, since large parts of the Neotropics are under anthropogenic pressure, a high percentage of possibly threatened species occurs.

The contribution of statistical physics to evolutionary biology

open access: yes, 2011
Evolutionary biology shares many concepts with statistical physics: both deal with populations, whether of molecules or organisms, and both seek to simplify evolution in very many dimensions.

Wright-fisher-like models with constant population size on average [PDF]

open access: yes, 2017
We first recall some basic facts from the theory of discrete-time Markov chains arising from two types neutral and non-neutral evolution models of population genetics with constant size.

Genetic diversity in introduced populations with Allee effect [PDF]

open access: yesarXiv, 2013
A phenomenon that strongly influences the demography of small introduced populations and thereby potentially their genetic diversity is the Allee effect, a reduction in population growth rates at small population sizes. We take a stochastic modeling approach to investigate levels of genetic diversity in populations that successfully overcame a strong ...

Stability of Underdominant Genetic Polymorphisms in Population Networks [PDF]

open access: yesarXiv, 2015
Heterozygote disadvantage is potentially a potent driver of population genetic divergence. Also referred to as underdominance, this phenomena describes a situation where a genetic heterozygote has a lower overall fitness than either homozygote. Attention so far has mostly been given to underdominance within a single population and the maintenance of ...

Exploring a Pool‐seq‐only approach for gaining population genomic insights in nonmodel species

open access: yesEcology and Evolution, 2019
Developing genomic insights is challenging in nonmodel species for which resources are often scarce and prohibitively costly. Here, we explore the potential of a recently established approach using Pool‐seq data to generate a de novo genome assembly for ...

Population genetic consequences of the Allee effect and the role of offspring-number variation [PDF]

open access: yesarXiv, 2013
A strong demographic Allee effect in which the expected population growth rate is negative below a certain critical population size can cause high extinction probabilities in small introduced populations. However, many species are repeatedly introduced to the same location and eventually one population may overcome the Allee effect by chance.

The Etruscans: A Population-Genetic Study [PDF]

open access: yesThe American Journal of Human Genetics, 2004
The origins of the Etruscans, a non-Indo-European population of preclassical Italy, are unclear. There is broad agreement that their culture developed locally, but the Etruscans' evolutionary and migrational relationships are largely unknown. In this study, we determined mitochondrial DNA sequences in multiple clones derived from bone samples of 80 ...
