“…This matches the information in the literature pertaining to the role of invasive plants in reducing biodiversity and leading to biotic homogenization of native plant communities [81]. Seedling establishment of X. strumarium is known to be promoted in native communities subject to human disturbance, a finding our study supports, and one reported for other exotic species in the region, such as Dodonaea viscosa in Malakand as reported by [59,82], and for P. hysterosporus in the same region by [65].…”

“…We found that seed germination rates of this species (75%) exceed those of other invasive plants, for example those reported for B. papyrifera (25%) [49]. Furthermore, the results of our discriminant analysis indicated higher sexual propagation and seed and fruit formation in this species compared to other regional invasive species as reported by [9,49,65].…”

“…Group-IV, hereafter reported as a community of X. strumarium and C. sativa, showed a distinct floristic composition, having IVI of D. innoxia (9.78%), Verbascum thapsus (5.29%) and P. hysterophorus (2.56%). The group-IV could be tentatively placed in a separate category based on its floristic composition, as recently proposed by [64] and subsequently accepted by [65]. The floristic composition of the X. strumarium and C. sativa community (Group-IV) differed from the former groups owing to the reduced IVI of some constituent species and the prominence of new species such Tagetes minuta (IVI = 2.98%) and Justicia adhatoda (IVI = 1.26%).…”

Xanthium strumarium L. is a globally successful invasive herb that has had significant negative ecological, economic and social impacts in many world regions. The present study was therefore conducted to evaluate the invasive potential and spatial distribution patterns of X. strumarium in heavily invaded plant communities of the semiarid regions of northern Pakistan. Investigations were based on data from 20 plants grown in the Herbarium at the University of Malakand, and from observations in 450 plots distributed across 45 stands representing habitats across Northern Province including open fields, hillocks and abandoned areas in both urban and rural areas. Multivariate analysis identified elevation, organic matter and organic carbon as the environmental variables most associated with communities invaded by X. strumarium. Increased soil silt was positively associated and available water was negatively associated with X. strumarium–invaded communities. These key environmental characteristics allowed us to identify four main associations: Group I: X. strumarium-C. sativa, Group II: X. strumarium-P. hysterophorus, Group III: X. strumarium-A. aspera and Group IV: X. strumarium-C. sativa. Other invasive species were observed, either exotic, such as P. hysterophorus, or indigenous, such as C. sativa and D. inoxia, often co-occurring and responding similarly to these factors. The results suggest that high temperature with drought stress could be a determinant of increasing population at lower elevations, whereas colder climates with adequate moisture are related to reduced populations at higher elevations, near the species’ upper range limits. It is recommend that the inclusion of appropriate, additional soil and climatic variables in species distribution models be implemented in order to better explain species’ ecological niches and help guide conservation and protection plans for native plant communities.

“…Parthenium (Parthenium hysterophorus L.), family Asteraceae, is a devastating and dangerous weed of many economically important crops (Ray, Gour, 2012). It is among the top ten worst weeds worldwide and is included in the world catalogue of aggressive species (Callaway, Ridenour, 2004;Kapoor, 2012;Khan et al, 2020). In 1955, it was accidentally introduced through imported food grains in the subcontinent (Hassanein et al, 2008).…”

“…Still, the current trends include biomass allocation, relative growth, and rate of assimilations ( Ullah et al, 2021 ). Invasive plants use morphological and physiological changes to adapt to shifting environmental conditions ( Khan et al, 2020 ). The biomass allocation and reproductive time variables have been demonstrated to be important predictors of plant fitness ( Claridge and Franklin, 2002 ).…”

The elevation is an important gradient across which the environmental variables and plant traits vary and is considered as a barrier to the recent global problem of plant invasion. However, certain invasive plants show plasticity traits to adapt and cope with the changes across the elevation. Silybum marianum (S. marianum) is one such invasive species widely spread in Khyber Pakhtunkhwa, Pakistan. Therefore, this study investigates the traits plasticity and invasive behaviors of this plant species across the elevation gradient. Plant functional traits (PFTs) and environmental variables were recorded in forty different low, middle, and high elevation sites. The plant shows a decrease in plant functional traits, i.e., above-ground plant height/plant, leaf length/leaf, leaf width/leaf, leaf dry weight/plant, vegetative dry weight/plant, and number of capitula/plant having the significance of p < 0.05. In contrast, the dry reproductive weight does not change significantly with elevation, while the root length increases across the elevation. The soil and environmental variables such as organic matter, lime percentage, and latitude significantly affected the PFTs. The importance value index of the species was also related to elevation and diversity indices, i.e., species richness, Shannon–Wiener diversity index, and evenness index, indicating that the invasion has strong effects on diversity. This study concludes that S. marianum has traits plasticity across the elevation and affects community diversity. Further investigation is required to understand the invasion and diversity parameters in a better way.
