Recent research on the seven most widespread forest trees in Europe has shown their ability to maintain their genetic diversity, despite millions of years of varying environmental conditions. This offers some hope as the world continues to face climate change. Phys.org reported on the studyoriginally appeared in Nature Communications.

Pascal Milesi, associate professor of plant ecology and evolution at Uppsala University, believes this is really positive: “These trees are keystone species on which many other species depend.”

The researchers focused on the genetic characteristics of these trees and were surprised to learn that they had high genetic diversity and were resilient to extreme changes in their climate, including an ice age. Milesi says they can potentially attribute the high genetic diversity to tree pollenbecause it can travel thousands of kilometers.

Due to the height of the trees and gusts of wind, tree pollen can fertilize other trees. significant distanceaccording to Allergy & Clinical Immunology. Great for biodiversity, not so much for your allergies.

“This is a welcome sign,” noted Milesi, author of the study. “Evolutionary processes that were at play in the past may also be useful in coping with today’s rapidity climate change“.

This study also supports the theory that protection pollinators is good for the environment. Preserving pollinator populations is important to humans because they protect our food supply and help maintain a healthy and diverse ecosystem. In the Amazon rainforest, pollinators have been deprived of the necessary resources, and researchers are already see alarming effects.

Trees do more than shed pollen. They also help to carbon sequestration — the process of storing carbon in vegetation, soil, etc. — as well as providing habitats for countless other species, contributing greatly to biodiversity.

As the list of threatened and extinct species continues to grow, Milesi said it’s not time to give up yet: “This study sends a positive signal about our forest and provides important information to help manage forest biodiversity in the face of climate change.
