Higher epigenetic diversity could alleviate the loss of genetic diversity

Genetic diversity is generally considered the chief determinant of evolutionary change, but epigenetic diversity is now recognized as another layer of heritable variation with potential adaptive consequences. Epigenetic diversity could sometimes (fragmented populations, stressing habitats) alleviate the loss of genetic diversity and provide an "evolutionary backup" mechanism for wild plants. This study compares genetic and epigenetic diversity in seven congeneric species pairs with restricted and widespread distributions in southeastern Spain. Results suggest that higher epigenetic diversity could alleviate the loss of genetic diversity in some populations of endemic plants, but also other plant features can be essential to understand the relationship between genetic and epigenetic diversities. informacion[at]ebd.csic.es: Medrano et al (2020) Comparative genetic and epigenetic diversity in pairs of sympatric, closely-related plants with contrasting distribution ranges in southeastern Iberian mountains.

Predictors of pollinator service

Pollinator service is essential for successful sexual reproduction and long?term population persistence of animal?pollinated plants, and innumerable studies have shown that insufficient service by...

Long-distance dispersal by migratory waterbirds

Modern literature on plant dispersal by birds focuses mainly on the importance of frugivory and scatter-hoarding, yet recent studies show that endozoochory by migratory waterbirds is an important...
