Is Poa annua a skin-changer? Annual-perennial life history shift enables the species to conquer Antarctica.

An extended lifespan of Poa annua may be of adaptive value during the invasion of harsh environments. Our aim was to investigate whether this trait is population-specific or general for the species. Individuals representing eight populations were cultivated under experimental conditions for two Antarctic growing seasons separated by polar winter conditions.

Rapid adaptation and extinction across climates in synchronized outdoor evolution experiments of .

Climate change is threatening species with extinction, and rapid evolutionary adaptation may be their only option for population rescue over short ecological timescales. However, direct observations of rapid genetic adaptation and population dynamics across climates are rare across species. To fill this gap, we conducted a replicated, globally synchronized evolution experiment with the plant for 5 years in over 30 outdoor experimental gardens with distinct climates across Europe, the Levant, and North America.

Unified system describing factors related to the eradication of an alien plant species.

Background: In the field of biological invasions science, a problem of many overlapping terms arose among eradication assessment frameworks. Additionally there is a need to construct a universally applicable eradication evaluation system. To unify the terminology and propose an eradication feasibility assessment scale we created the Unified System for assessing Eradication Feasibility (USEF) as a complex tool of factors for the analysis of eradications of alien (both invasive and candidate) plant species.

How much of the invader's genetic variability can slip between our fingers? A case study of secondary dispersal of on King George Island (Antarctica).

We studied an invasion of on King George Island (Maritime Antarctic). The remoteness of this location, its geographic isolation, and its limited human traffic provided an opportunity to trace the history of an invasion of the species. was recorded for the first time at H.
