Exempel på monoculture

• Agroecological concepts are then introduced and applied to monocultures, intercropping and agroforestry.

• Furthermore, genes vulnerable to 'boom and bust' cycles are generally short-lived when deployed in monocultures.

• Further, genes deployed in monocultures of single cultivars may be more vulnerable to 'boom and bust' cycles.

• Especially under low input conditions, the agronomic performances of species mixtures have been reported to be superior to those of monocultures.

• In the present study, we examine possible underlying behavioural mechanisms that contribute to the difference in abundance of insects in poly- versus monocultures.

• If we have tended to see sugar and coffee as monocultures, for this period at least we are wrong.

• Both strip-crops and row intercrops can be considered more ecologically complex systems than traditional monocultures.

• A stable and balanced agrarian economy had degenerated into precarious monocultures and backwater towns.

• Much research is now directed to the vegetative propagation of high-yielding clones, despite the potential danger of growing genetically identical monocultures over wide areas.

• Therefore, grass monocultures, grass and white clover mixtures and grass, white clover and forbs mixtures were established in the field.

• The yield of cultivated plants is threatened by competition and destruction from pests, especially when grown in large-scale monocultures or with heavy fertilizer applications.

• Until now, most of the diversity studies have focused on rainforest ecosystems and have neglected monocultures like oil palm plantations.

• A fundamental question concerning crop diversification is which mechanisms determine pest population size in polycultures compared to monocultures.

• Patterns of ingestive behaviour of sheep continuously stocked on monocultures of ryegrass or white clover.

• Condensed tannin concentration of rhizomatous and nonrhizomatous birdsfoot trefoil in grazed mixtures and monocultures.
