The potential for biological control on cryptic plant invasions

摘要: Abstract Cryptic invasions can be defined as ‘the occurrence of an invasive species or genotype that was not previously recognised alien in origin distinguished from other aliens’. Such result negative impacts on the recipient ecosystems and disturb evolutionary history native plant populations. Many cryptic have become so problematic there is a need to implement control measures. This paper explores potential for biological implemented means managing invasions. Firstly, defines different forms invasion, differentiating between interspecific intraspecific invasions; this hierarchy influences how detect, study ultimately when occur. Secondly, unique challenges associated with programmes are addressed, including: level host specificity agents, hybridisation species/lineages target weed, role enemy release presence closely related species/lineages, review stakeholder conflicts interest legislation. Biological has been shown possible, however process will more difficult complex than controlling traditional targets likely take up time resources. If these overcome, then against should able proceed maintain same standards programmes.
