1. The factors associated with plant species’ endangerment and (conversely) invasiveness are of broad interest due to their potential value in explaining the causes and consequences of population status. While most past work has focussed on ecological variables, recent work suggests that genetic attributes may be strongly associated with plant species status. 

Interspecific variation in ploidy as a key plant trait outlining local extinction risks and community patterns in fragmented landscapes

TLDR
The objective of this study was to evaluate the phytochemical properties of polyploidy in response to the presence of E.coli in the E. coli O157:H2O 2.1.

Trait responses of invasive aquatic macrophyte congeners: colonizing diploid outperforms polyploid

TLDR
The results suggest the congeners have alternate colonization strategies, and trait responses underlying their success may change with ontogeny, and management strategies for invasive Ludwigia species should therefore be tailored for specific cytotypes and unique characteristics of their life stages.

Spatial proximity between polyploids across South American frog genera

TLDR
This work test the expectation that polyploid taxa occur more frequently in extreme or disrupted environments than their diploid counterparts, whether due to increased adaptive potential, environmental resilience or cross‐ploidy competition.

Opposing macroevolutionary and trait-mediated patterns of threat and naturalization in flowering plants

TLDR
A pronounced signature of naturalization and threat across plant families suggests that both trait syndromes have coexisted over deep evolutionary time and that neither strategy is necessarily superior to the other.

Polyploidy determines the stage of invasion: clues from Kashmir Himalayan aquatic flora

TLDR
A clear pattern is depicted that non-invasive species are disproportionately more diploids with lower ploidy ratios, while invasive plant species on the contrary exhibit higher chromosome counts, thereby being predominantly polyploids.

Hitting the right target: taxonomic challenges for, and of, plant invasions

TLDR
Modern taxonomy needs to integrate both classical and new concepts and approaches to improve the accuracy of species identification and further refine taxonomic classification at the level of populations and genotypes in the field and laboratory.

Resprouting potential of rhizome fragments from invasive macrophyte reveals superior colonization ability of the diploid congener

TLDR
Compared to previous shoot fragment studies with Ludwigia, rhizome fragments appear to have much greater growth potential, suggesting that management strategies should minimize disturbance to prevent fragmentation and dispersal of below-ground structures.

Global grass (Poaceae) success underpinned by traits facilitating colonization, persistence and habitat transformation

TLDR
A diverse set of functional traits linked to dispersal, establishment and competitive abilities are identified over the phylogeny of the Poales, spanning the grasses and their relatives, and demonstrated the accumulation of traits since monocots originated in the mid‐Cretaceous.

Geographic and genetic variation in susceptibility of Butomus umbellatus to foliar fungal pathogens

TLDR
These results demonstrate that two widespread B. umbellatus genotypes exhibit different susceptibility to pathogens and effectiveness of pathogen biological controls may depend on local conditions.

A theory of seed plant invasiveness: The first sketch

Traits of invasives reconsidered: phenotypic comparisons of introduced invasive and introduced noninvasive plant species within two closely related clades.

TLDR
Comparisons of phenological, architectural, size, and fitness traits of several introduced invasive species to introduced noninvasive species within two genera of Asteraceae suggest differences in invasiveness between closely related species is better explained as the result of complex trait interactions and specific introduction histories.

The biogeography of plant reproduction: potential determinants of species’ range sizes

TLDR
It is argued that genetic diversity, colonization ability, or a combination of both factors may influence plant species’ range sizes, and that a broader survey of plant taxa will resolve the two modes from that of the outcrossing species.

Factors Associated with Alien Plants Transitioning from Casual, to Naturalized, to Invasive

TLDR
The capacity of alien species to naturalize and become invasive evolved largely independently in several phylogenetic lineages, suggesting that a combination of species traits and other variables is likely to produce the most accurate prediction of invasions.

Threat or invasive status in legumes is related to opposite extremes of the same ecological and life‐history attributes

TLDR
The results show that species do demonstrate particular susceptibility to either fate based on their evolved traits, and that traits generally correlated with invasiveness are also those that correlate with a reduced probability of becoming threatened.

Conifers as invasive aliens: a global survey and predictive framework

TLDR
Information is summarized on naturalized and invasive conifers worldwide ( data from 40 countries, some with remote states/territories), and findings are consistent with earlier predictions made using a discriminant function derived from attributes of invasive and noninvasive Pinus species.

Plant invasion across space and time: factors affecting nonindigenous species success during four stages of invasion.

TLDR
A general framework is outlined that attempts to connect patterns of plant invasion to processes underlying these patterns at four well-established spatio-temporal stages of the invasion process: transport, colonization, establishment, and landscape spread.

Applying DNA C-values to evaluate invasiveness of angiosperms: validity and limitation

TLDR
Compared DNA 1C-values and basic genome sizes in angiosperms suggest that the selection favors polyploids in weeds at least partly because of the downsizing of basic genome size along with polyploidization.
