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.
