Abstract Standing genetic variation in fitness-related traits is critical to determine how fast populations can adapt to climate warming but is unknown for many species. Here we show that heritable genetic variation in heat tolerance in reef-building coral populations is widespread and strongly associated with selective pressure imposed by marine heatwaves. Our findings suggest that coral populations may be adapting to warming consistent with recent increases in their upper thermal limits.
Abstract Astrocyte dysfunction has previously been linked to multiple neurodegenerative disorders including Parkinson’s disease (PD). Among their many roles, astrocytes are mediators of the brain immune response, and astrocyte reactivity is a pathological feature of PD. They are also involved in the formation and maintenance of the blood-brain barrier (BBB), but barrier integrity is compromised in people with PD.
