mtDNA recombination in a natural population [PDF]
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]
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
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

CHARACTERISTICS OF WINTER ROOST AND ACTIVITY SITES OF WILD TURKEYS IN MINNESOTA
: Selection of winter microhabitats that minimize heat loss from wind and radiation can potentially reduce thermoregulatory energy requirements and increase survival of wild turkeys (Meleagris gallopavo).

DIABETIC RETINOPATHY IN A NATURAL POPULATION [PDF]
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 (
