There are many other examples of crop mimicry by weeds and their seeds, with the latter helping weed seeds get harvested, stored, and replanted along with crops.
These include examples of crop plants responding to environmental changes in situ and invasive plants or domesticates encountering new climate regimes as they expand their distribution [ 63- 67].
When the respondents were asked about their knowledge on "the difference in crop and forage production due to Eucalyptus woodlot in the nearby area," they were thinking about the adverse ecological impacts of Eucalyptus, for example, reduction of crop and forage production especially when Eucalyptus is planted around farm boundaries or on grazing lands.
In Africa, for example, 70percentt of crop production depends on women, yet women own less than 2percentt of the land.
The chapter provides a series of examples of crops that have been biofortified through biotechnology, including rice, banana, potato, cassava, and sorghum.
Brassica napus L. is one of the most economically important polyploid oil crops and has been broadly studied as an example of polyploid crop.
It is a classic example of a crop designed for intensive agriculture," says Richard Sanders, policy and communications director at Elm Farm Research Centre, which develops and supports sustainable land use.
Measured performance data during a 28-day closed operation period are compared with the specified functional requirements, and an example of inferring crop growth parameters from the test data is presented.
Here, we illustrate one example of how crop science can stimulate evolutionary research on genetics and mechanisms of adaptation in natural systems, and where evolutionary and ecological approaches might facilitate the search for agronomically valuable traits.
IFOAM states that "this principle roots organic agriculture within living ecological systems...for example, in the case of crops this is the living soil; for animals it is the farm ecosystem; for fish and marine organisms, the aquatic environment".
