“…Invasive species are species of interest due to their ability in colonizing and distribution into new environments. Despite this interest, the influencing parameters in successful invasion are undetermined or poorly studied (Rollins et al 2013;Ueno et al 2015).…”

“…Inter Simple Sequence Repeats (ISSR) markers are simple, fast and reproducible, therefore can be a great choice for study of population genetic diversity (Wolfe et al 1998). Moreover, since this technique has been previously used for genetic structure of other invasive plants (Innis et al 2011;Ueno et al 2015;Vicente et al 2018), it is demonstrated to be suitable for such studies.…”

markers (ISSR) were used to study the genetic variability on 11 populations of this species. Genetic diversity parameters, genetic distance and gene flow were determined. Genetic variation at inter-and intra-populational level were evaluated by different methods. AMOVA and structure analyses revealed high genetic diversity within populations. Mantel test revealed a significant correlation between genetic and geographic distances. Between populations a limited gene flow was observed. It is concluded that local adaptation, low gene exchange and genetic drift can affect genetic diversity of F. convolvulus. Despite selfcompatibility of this species, it is proposed that out-crossing may be occur because of higher genetic variation among populations of this taxon.

“…To this end, further investigations focusing on the genetic basis of invasiveness can not only offer vital information for elucidating evolutionary mechanisms underlying the successful establishment of IAS, but also provide an efficient guideline for controlling and management of the IAS in the native ecosystems. Indeed, many attempts have been made to explain how the genetic variability contributes to the colonization of IAS to novel environments (Tsutsui et al, 2000; Kolbe et al, 2004; Hodgins et al, 2013; Ueno et al, 2015). For example, high level of genetic diversity is supposed to contribute high adaptability to IAS to cope with diverse stresses caused by natural selection (Ahlroth et al, 2003; Prentis et al, 2008; Wang et al, 2012; Hufbauer et al, 2013).…”

Biological invasion represents a global issue of concern due to its large negative impacts on native ecosystems and society. Elucidating the evolutionary history and genetic basis underpinning invasiveness is critical to understanding how alien species invade and adapt to novel environments. Smooth cordgrass (Spartina alterniflora, 2n = 6x = 62) is a notorious invasive species that causes heavily negative effects on native ecosystems worldwide. Here we addressed the evolutionary mechanisms underlying the invasion and dispersal history of this species along the China coast in the past decades. We employed nine microsatellites and three chloroplast fragments to investigate phylogeographic structure and genetic diversity of 11 native US and 11 invasive Chinese S. alterniflora populations. Demographic history simulation was also performed for both the native and invasive populations, respectively. Comparative genetic analyses of these natural populations revealed that although all the Chinese populations were introduced only once, high level of genetic diversity with weak geographic structure was observed. In particular, both the genetic features and mathematical simulation illustrated very recent population expansion in the Chinese populations. We found that genetic variants identified in native US populations were mixed in the Chinese populations, suggesting the recombination of these original variants during the invasion process. These genetic attributes indicate that Chinese populations might not have experienced a genetic bottleneck during the invasion process. High genetic diversity and genetic admixture might have contributed to the success of invasion of S. alterniflora in China. Our study provides a framework of how the smooth cordgrass spreads along the China coast as well as its potential genetic mechanisms underlying the invasion.

“…The genetic constitution of an invasive species changes from its native to non‐native ranges which in turn can lead to variation in genetic diversity distribution within and between populations (Gaudeul et al , Ueno et al ). The present study investigated the genetic diversity and population structure of P. hysterophorus growing in different areas of Jammu and Kashmir.…”

One of the fundamental questions in invasion biology is why an alien species successfully invades one region but fails to do so in another region. In this regard, the recently emerging molecular ecology tools have made it possible to understand the genetic basis of invasion success and/or failure of alien species in different regions. Here we report the results of studies of the population genetic structure and diversity of Parthenium hysterophorus L. – a global plant invader – from two climatically distinct Himalayan regions: Jammu and Kashmir. While P. hysterophorus has successfully invaded across the subtropical Jammu region, it failed to invade the neighbouring temperate Kashmir region. The results, based on the ISSR data, revealed that the populations from Jammu were genetically more diverse than those from Kashmir. This conclusion was further supported by cluster analysis which grouped all the five populations of P. hysterophorus from Jammu region, but clearly separated out the Kashmir population. It is plausible that this low genetic diversity of P. hysterophorus in the latter region, along with the environmental barrier (i.e. temperate climate), has so far prevented the naturalisation and wide spread of this invasive plant species in Kashmir. The research insights from the present study, therefore, have potential implications for understanding the genetic basis of plant invasions.
