About this Research Topic
Over the course of evolution, forest trees have developed a wide array of physiological and metabolic responses to confront and overcome adverse conditions. Whereas responses of forest tree species to abiotic stresses have been intensively studied, their responses to biotic stresses such as pest and pathogen attacks are less understood. Filling this knowledge gap is fundamental because, both intensity and frequency of insect and pathogen outbreaks are dramatically increasing as a consequence of rapid climatic change; a fact that seriously threatens the sustainability of forests worldwide.
A large number of studies has shed light into how environmental stressors due to climate change (e.g. warming, drought, nitrogen deposition, elevated CO2 emissions) influence pests and pathogens performance (i.e. direct effects of climate change on both biotic factors). However, how such environmental stressors influence plant defensive responses which in turn determine their infestation patterns (i.e. plant-trait mediated indirect effects) is less understood. To address this topic, it is essential to provide more information about how global warming affects the physiological and metabolic defensive responses across a broad range of tree, herbivore, and pathogen species in boreal, temperate and tropical regions.
This article collection aims at assembling innovative studies that investigate the ecophysiological defensive responses of forest trees to insect and pathogen attacks. For this Article Collection, original research papers based on experimental, theoretical and simulation approaches are strongly welcomed. Additionally, given some exciting recent advances and the general interest in the field, review papers can be also accepted, in an effort to adequately summarize the state-of-the-art in the topic of the interactions between trees and insects/pathogens.
