Biology - Research Paper usageFor instance, Bellard, McCarthy and Meekins studied on genetic variation as well as biogeography of genus Alliaria petiolata in due north America in 1st January 2001. According to their findings, Alliaria petiolata varied in not only phenology, however also morphology across all the native plants in which it grew ( Bellard, McCarthy and Meekins 161). They also form extinct that Alliaria petiolata also varied in terms of seed dormancy. In their results, they also stipulate that Alliaria petiolata is a hexaploid plant species based on n=7. In tandem to Bellard, McCarthy and Meekins findings, Hanson and McCarthy also claim that Alliaria petiolata is atomic number 53 of the plant species that have contributed to the loss of many indigenous plants in North America. They assert that Alliaria petiolata is a non-indigenous plant species that belongs to Brassicaceae family (Hanson and McCarthy 68). According to them, it was first identified in North America in archean 1868. Unlike other Brassicaceae, Hanson and McCarthy spotulate that Alliaria petiolata spreads in the introduced environment very fast because of its monopolization of resources. To justify their point, they start on how it took it only 20 years to spread throughout the northeastern parts of North America. By 1991, Alliaria pestiolata had spread to Canada and was identified in 30 U.S states (Blazevic and Mastelic 607). In tandem to this, Bossodorf and Prati also found out that it is through characteristic features and adaptations that Alliaria petiolata managed to invade and successively destroy North American woodlands (Bossdorf and Prati 1). They also found out that the effects of Alliaria petiolata varied with plant species some species such as G. laciniatum was least peeled to the allelopathic interference. In their study, Meiners and Pisula also found out that invasive plant species conquer and advance successfully in introduced areas because of allelopathy. Acco rding to them,
