Ecosphere, Volume 11, Issue 5, May 2020., 2020 Abstract Greenhouse crops are thought to be simplified ecosystems because they often consist of monocultures that are relatively isolated from their environment. However, insect pests are still able to colonize these protected crops, which threaten their yields.

Do interactions between plant roots and the rhizosphere affect parasitoid behaviour? [PDF]
, 2004 Multitrophic interactions are powerful forces shaping the structure of living communities. Plants encounter a great diversity of organisms in their environment: some of these interactions are beneficial (e.g. symbiotic fungi and insect pollinators) while
