CHANGES IN GLOBAL DNA METHYLATION UNDER CLIMATIC STRESS IN TWO RELATED GRASSES SUGGEST A POSSIBLE ROLE OF EPIGENETICS IN THE ECOLOGICAL SUCCESS OF POLYPLOIDS

Abstract Polyploidization drives the evolution of grasses and can result in epigenetic changes, which may have a role in the creation of new evolutionary lineages and ecological speciation.As such changes may be inherited, they can also influence adaptation to the environment.Populations from different regions and climates may also differ epigeneti

Abstract Background Health services have a clear role in the treatment of obesity and diseases linked to obesity but a less well-established role in prevention, particularly in hospital and community-based health services.Methods The aim of this research was to examine whether and how hospital and community-based health services incorporate adult o

Abstract Background Vector control remains the primary defense against dengue fever.Its success relies on the assumption that vector density is related to disease transmission.Two operational issues include the amount by which mosquito density should be reduced to minimize transmission and the spatio-temporal allotment of resources needed to reduce

Fear protects organisms by increasing vigilance and preparedness, and by coordinating survival responses during life-threatening encounters.The fear circuit must thus operate on multiple timescales ranging from preparatory sustained alertness to acute fight-or-flight responses.Here we studied the brain basis of sustained and acute fear using natura
