Impact of Sorghum halepense (L.) Pers. on the Species Richness in Native Range

Do non-native and dominant native species carry a similar risk of invasiveness? A case study for plants in Turkey

“…For instance, among the study species, P. americana has been reported from agricultural, forest and coastal habitats but as problematic especially in arable lands, due to shading and harvesting difficulties, such as for kiwi fruit (Sezer and Kolören 2019) and tea (Terzioğlu and Ergül Bozkurt 2020). Similarly, the screened native species have also been reported in several habitats including arable lands (Yazlık and Tepe 2001;Kaçan and Boz 2015;Yazlık and Üremiş 2022). For instance, the incidence of P. australis was determined as 48% and the density as 12 plants/m 2 in traditional vineyards of Manisa province in the Aegean Region of Turkey (Kaçan and Boz 2015).…”

“…agriculture, coastal, forest: Table 2) and human influence has a high share in their spread. In this respect, the most important factors are the 'weed' status of these species in agricultural habitats combined with their competitive abilities such as morphological characteristics (Yazlık and (Bímová et al 2003), high biomass (van Kleunen et al 2010;Hejda 2013;Canavan et al 2019) and a large number of branches/tillerings (Hejda 2013;Yazlık and Üremiş 2022) were all traits associated with high invasiveness. In addition, serious problems have been reported regarding the presence of these species in their habitats (Table 2), which is a major reason for their high-risk scores, hence irrespective of their origin.…”

“…Under the challenging conditions of global change, a major task of invasion biology is to identify those high-risk species that are more likely to cause negative impacts. Usually, species that are either non-native invasive or 'expanding native' (Simberloff et al 2012;Díaz et al 2019;Essl et al 2019;Simberloff 2022;Yazlık and Üremiş 2022) and that become dominant in natural habitats may exert direct or indirect impacts on community structure and composition, species interactions and ecosystem functions, all of which can result in a 'domino effect' (Hawkins et al 2015;Pyšek et al 2017Hulme and Bernard-Verdier 2018;Díaz et al 2019;Brundu et al 2020).…”

“…Several mechanisms including the availability of free niches and increased competitive ability are involved in the invasion process by non-native species (Catford et al 2009;Hiero and Callaway 2021). Yet, several plant species within their native range behave like invasive plants (Pyšek et al 2004;Simberloff 2011;Simberloff et al 2012;Hejda et al 2021;Yazlık and Üremiş 2022). Although there is an ongoing debate as to whether the impacts of non-native invasive plants differ from those of expanding native (dominant) plants (Simberloff et al 2012(Simberloff et al , 2013Hejda et al 2021), there is solid evidence that both non-native species' invasions and the spread of dominant native species may pose threats to biodiversity and sustainability (Hejda et al 2021;Yazlık and Üremiş 2022).…”

This is also because native dominant plant species are likely to be invasive outside their native range (Pyšek et al 2009;Phillips et al 2010;Hejda et al 2021).…”
