Abstract Purpose of the Review One of the major threats to tree health, and hence the
resilience of forests and their provision of ecosystem services, is new and emerging pests …

Passive acoustic monitoring has become increasingly popular as a practical and cost-
effective way of obtaining highly reliable acoustic data in ecological research projects …

Forest canopies are complex and highly diverse environments. Their diversity is affected by
pronounced gradients in abiotic and biotic conditions, including variation in leaf chemistry …

Invertebrate herbivory is a crucial process contributing to the cycling of nutrients and energy
in terrestrial ecosystems. While the function of herbivory can decrease with land‐use …

Urbanization is an important driver of the diversity and abundance of tree‐associated insect
herbivores, but its consequences for insect herbivory are poorly understood. A likely source …

To what extent particular plant defences against herbivorous insects are constitutive or
inducible will depend on the costs and benefits in their neighbourhood. Some defensive …

Experimental studies of biotic interactions in real field conditions are essential to understand
the structure and functioning of ecological networks. The use of artificial caterpillars to mimic …

Urbanization is one of the main drivers of biotic homogenization in bird communities
worldwide. Yet, only a few studies have addressed its functional consequences on the top …

Assisted migration is a tree‐planting method where tree species or populations are
translocated with the aim of establishing more climate‐resilient forests. However, this might …

Aim Climate is a major driver of large‐scale variability in biodiversity, as a likely result of
more intense biotic interactions under warmer conditions. This idea fuelled decades of …
