#Plant populations within fragmented #landscapes retain persistent #genetic signatures of past demographic crashes, specifically reduced genetic diversity and increased inbreeding, which remain detectable long after the population size appears to have recovered.

Plants retain a ‘genetic memory’ of past population crashes

While past research has shown that human‑caused habitat fragmentation can harm plant populations

#Aging in #humans and the reasons that support high #lifeexpectancies are of general applied interest. Of particular research interest are so-called #supercentenarians in #Brazil. As this population is considered genetically most #diverse due to indigenous, European, and African influences. According to the paper below, the secret to aging in Brazil may lie primarily in a #genetic #predisposition.
