AI Article Synopsis
- The study focused on two types of epiphytic cyanolichens, Nephroma laevigatum and N. parile, using microsatellite markers to explore their population structures and gene flow due to their different dispersal methods.
- Researchers identified 12 microsatellite loci for N. laevigatum and 14 for N. parile, finding that N. laevigatum had a higher range of genetic diversity due to its sexual reproduction compared to the mainly asexual N. parile.
- The new markers developed will help in understanding how reproductive strategies affect population dynamics and community structure in these two species.
Article Abstract
Premise Of The Study: Microsatellite markers were characterized for two epiphytic cyanolichens, Nephroma laevigatum and N. parile (Nephromataceae), and will be used to investigate population structure and estimate gene flow among populations of these two closely related species with contrasting dispersal modes. •
Methods And Results: Twelve and 14 microsatellite loci were characterized for N. laevigatum and N. parile, respectively. Allele number in N. laevigatum ranged from three to 13 per locus, while in N. parile there were from two to six alleles per locus. As expected, the sexually reproducing N. laevigatum had higher genetic diversity than the predominantly asexual N. parile. •
Conclusions: This new set of markers is suitable for studying population structure and providing insights into gene flow among populations and for understanding processes of diversification. Compared between the species, they will facilitate an understanding of the influence of contrasting reproductive strategies on population and community structure.

Genetic variation is expected to be influenced by the interaction between reproductive mode and dispersal traits on the one hand and environmental and habitat setting affecting establishment success on the other. We evaluated how environmental/habitat setting affects population genetic variation (i.e.
