Climate Change Alters Temperate Forest Canopies and Indirectly Reshapes Arthropod Communities

Global change challenges the adaptive potential of forests. Large-scale alterations forest canopies have been reported across Europe, and further modifications are expected in response to predicted changes drought windstorm regimes. Since dynamic interfaces between atmosphere land surface, communities canopy-dwelling insects at forefront major both direct indirect effects climate change. First, we briefly introduce factors shaping arthropod canopy temperate Second, cover significant impacts a decline on structure functioning, more specifically its contrasted insect microhabitats, trophic resources microclimates. Deleterious may be for several guilds leaf-dwelling insects. Nonetheless, could also lead transient or long-lasting resource pulses other guilds, especially saproxylic species depending deadwood substrates tree-related microhabitats.
