Spatial genetic structure (SGS) in plants, namely the spatial aggregation of genetically related individuals, has been linked to several biological attributes of species, such as breeding system and life form. However, little is known about SGS in ferns, which together with lycopods are unique among land plants in having two free-living life stages.
Tree ferns
Rates of molecular evolution in tree ferns
Variation in the rates of molecular evolution among lineages (heterotachy) has been widely documented throughout the tree of life. However, the processes influencing the speed at which DNA evolves in different lineages are not well understood. Continue reading
Species diversification in scaly tree ferns
Variation in species diversity among lineages is a major feature of evolution. However, factors affecting species diversification remain largely unexplored, specially in plants. Continue reading
