European trees continue to adapt through millions of years of climate change

Good news! Nature is much more resilient to climate change than what we are supposed to believe and despite all that propaganda and demagoguery!

Keep in mind: Global Warming is a hoax and Climate Change is a religion! It is being used as a pretext by Big Government and the elite to interfere with our lives. It is among the greatest scams and scandals of the last 30 years!

"... The trees, the researchers found, were able to do this despite sharp declines in population range and numbers, especially during ice ages. ..."

From the abstract:

"The effect of past environmental changes on the demography and genetic diversity of natural populations remains a contentious issue and has rarely been investigated across multiple, phylogenetically distant species. Here, we perform comparative population genomic analyses and demographic inferences for seven widely distributed and ecologically contrasting European forest tree species based on concerted sampling of 164 populations across their natural ranges. For all seven species, the effective population size, Ne, increased or remained stable over many glacial cycles and up to 15 million years in the most extreme cases. Surprisingly, the drastic environmental changes associated with the Pleistocene glacial cycles have had little impact on the level of genetic diversity of dominant forest tree species, despite major shifts in their geographic ranges. Based on their trajectories of Ne over time, the seven tree species can be divided into three major groups, highlighting the importance of life history and range size in determining synchronous variation in genetic diversity over time. Altogether, our results indicate that forest trees have been able to retain their evolutionary potential over very long periods of time despite strong environmental changes."

Trees continue to adapt through millions of years of climate change "In some positive news, a big and broad study has found that 7 of Europe’s most common forest trees have adapted to major climatic shifts and protected their genetic diversity."

Adaptability of trees persists after millions of years of climate change (original news release) "Seven of the most common forest trees in Europe have been shown to be able to shelter their genetic diversity from major shifts in environmental conditions. This is despite their ranges having shrunk and the number of trees having fallen sharply during ice age cycles. ..."
