Dynamics of biotic resistance to plant invasions

open access: yesBiological Reviews, EarlyView.
ABSTRACT Biotic resistance, the reduction in invasion success caused by native communities, plays an important role in the long‐term dynamics of biological invasions. A large body of empirical research on biotic resistance has accumulated since the last comprehensive review on the subject 20 years ago, enabling us to achieve a refined understanding of ...

Effects of increasing weed‐beet density on sugar‐beet yield and quality

open access: yesAnnals of Applied Biology, 1989
SummaryWeed beets are an increasing problem in many sugar‐beet crops in many countries. At present about one sugar‐beet field in four in England is infested with weed‐beet seed. Control in other crops can be achieved using selective herbicides but in sugar beet the weed beets, many of which are of annual habit, are not easily controlled and often ...
