Higher epigenetic diversity could alleviate the loss of genetic diversity

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.

Las altas temperaturas están provocando que las lagunas y las marismas de Doñana pierdan agua rápidamente

Las altas temperaturas están provocando que las lagunas y las marismas de Doñana pierdan agua rápidamente
La superficie inundada en la marisma es de un 78% pero la profundidad es escasa. Por otra parte, sólo el 1,9% de las lagunas temporales están inundadas. Las precipitaciones crean una oportunidad para la cría de aves acuáticas, pero su éxito dependerá de la duración del agua disponible

Illegal wildlife trade, a serious problem for biodiversity and human health
A research team led by the Doñana BIological Station and the University Pablo de Olavide have detected wild-caught pets in 95% of the localities in the Neotropic and warns of the risk of zoonotic outbreaks

Urbanization and loss of woody vegetation are changing key traits of arthropod communities

Urbanization and loss of woody vegetation are changing key traits of arthropod communities
Urbanization is favouring smaller beetle species and larger spider species with greater dispersal capacity.

The loss of woody areas is linked to a decline in the duration of the activity period, a higher tolerance to drought, and less dispersal capacity in both groups.

Blood lead levels in an endangered vulture species decreased following restrictions on hunting practices

Blood lead levels in an endangered vulture species decreased following restrictions on hunting practices
Canarian Egyptian vulture was on the verge of extinction at the end of the 20th century. At that time, studies revealed that lead poisoning was a serious problem for the population’s survival. The work has been possible thanks to the monitoring carried out since 1998 by the Doñana Biological Station in collaboration with the Canarian authorities.
