mtDNA recombination in a natural population [PDF]

open access: yesProceedings of the National Academy of Sciences, 1998
Variation in mtDNA has been used extensively to draw inferences in phylogenetics and population biology. In the majority of eukaryotes investigated, transmission of mtDNA is uniparental and clonal, with genotypic diversity arising from mutation alone. In other eukaryotes, the transmission of mtDNA is biparental or primarily uniparental

Natural selection and population dynamics [PDF]

open access: yesTrends in Ecology & Evolution, 2006
To what extent, and under which circumstances, are population dynamics influenced by concurrent natural selection? Density dependence and environmental stochasticity are generally expected to subsume any selective modulation of population growth rate, but theoretical considerations point to conditions under which selection can have an appreciable ...

Genetic parallelism between European flat oyster populations at the edge of their natural range

open access: yesEvolutionary Applications, 2023
Although all marine ecosystems have experienced global‐scale losses, oyster reefs have shown the greatest. Therefore, substantial efforts have been dedicated to restoration of such ecosystems during the last two decades. In Europe, several pilot projects

DIABETIC RETINOPATHY IN A NATURAL POPULATION [PDF]

open access: yesAustralian Journal of Opthalmology, 1983
AbstractMost epidemiological studies of diabetic retinopathy have been based on clinic populations. This produces a bias for the more severe cases and later stages of the disease. To avoid this bias, 1567 Micronesian adults of Nauru (82% of total adult population) were examined. Diabetic retinopathy was classified by both the World Health Organization (
