Pines detect insect sex pheromones and protect themselves from infestation

Through research conducted on young Scots pine trees and Diprion pini, a sawfly common to conifer forests in the Northern Hemisphere, scientists have shown, for the first time, how trees take steps to protect themselves against insect infestation even before eggs are laid on them.

The expansion of the Oaks "chokes" the forests of the Iberian Peninsula

A study conducted by researchers at the CREAF and the Autonomous University of Barcelona demonstrates that many pine populations of the Iberian Peninsula are in decline. The study foresees a very unfavorable scenario for some pine species with predicted climate change, which would see the pines negatively affected by both the expansion of the holm-oak, as well as an increase in drought and fire.
