Recombination and clonal propagation in different populations of the lichen Lobaria pulmonaria

Article Abstract:

Six polymorphic microsatellite loci are used to investigate whether recombination is common in natural populations, and to assess if and how clonal reproduction influences the spatial genetic structure within populations of the epiphytic lichen species Lobaria pulmonaria. It was observed that the presence of recurring multilocus genotypes influenced the spatial genetic structure only within low-density population.

Testing for clonal propagation

Article Abstract:

The application of an appropriate measure of relative gene association to the characterization of sexually produced multilocus genotypes is demonstrated. The method involves obtaining an independent estimate of the relative gene association for the genotype, estimating the genotype frequency and frequencies of genes appearing in the genotype and determining the lower and upper bounds for the genotype.

Mating patterns and contemporary gene flow by pollen in a large continuous and a small isolated population of the scattered forest tree Sorbus torminalis

Article Abstract:

The article discusses about the study to analyze the effect of population size and spatial isolation on the contemporary pollen flow and mating trends of the small, isolated populations and a large, continuous population of the insect-pollinated tree types Sorbus torminalis for two years is performed.
